- 118 - Pacific War - The battle of Eniwetok, February 20-27, 1944

Last time we spoke about Operation Hailstone, the continued drive upon Madang and the horrible massacre during the Indian Ocean Raid of 1944. Operation Hailstone saw what was once called the Gibraltar of the Pacific, Truk nearly annihilated. The demoralized and understrength Japanese could not hope to contest the air strikes and naval bombardment. Vice-Admiral Kobayashi Masami was held responsible for the defeat and was relieved of his command. Over on New Guinea the Australians were continuing their drive to Madang, killing and taking prisoner all the Japanese they could along the way. Then over in the Indian Ocean, Vice-Admiral Takasu Shiro unleashed a raid against allied shipping, a rarity for the Japanese. Unfortunately the raid devolved into a singular attack against the British steamer Behar. A needless and cruel massacre was performed aboard the Tone, killing 65 to a possible 100 people. Such actions would only see justice after the war.

This episode is the battle of Eniwetok

Operation Flintlock was a huge success, Kwajalien was seized incredibly fast and the invasion of Majuro saw no Japanese even on the atoll. Because of this the allied war planners had to shuffle the schedule and thus was born Operation Hailstone and the invasion of Eniwetok. Eniwetok had been originally slabbed for May, but it seemed obvious the Japanese power in the Marshalls was crumbling a lot faster than anticipated. Consequently, Admiral Nimitz knew it would be necessary to capture the atoll to give shelter to all the ships he intended to deploy westward in the drive against the Japanese inner empire. Since it now seemed Brigadier-General Thomas Watson’s 8000 reserve troops of the 22nd Marines and the 106th Regiment would no longer be required, Admirals Spruance and Hill began preparing them for the invasion of Eniwetok. 

The operation was codenamed Catchpole and the war planners would only have 12 days to prepare. Moving up the invasion of Eniwetok required stripping the new garrisons of Kwajalein Island and Roi-Namur of manpower and supplies. The landing boat crews were greens, not trained with the troops. General Watson reported “the infantry, amphibian tractors, amphibian tanks, tanks, aircraft, supporting naval ships, and most of the staffs concerned had never worked together before.” Nevertheless, the forces available for the operation would be plentiful and well equipped. Having gone through the horribly bloody assault on Tarawa, Admiral Hill was relieved to have a large number of amtracs. The Army’s 708th Provisional Amphibian Tractor Battalion would sail with 119 LVTs, most of which were the heavily armored newer models. As Hill would remark later “At Eniwetok, I felt like a millionaire, but at Tarawa, I was a pauper.”

Admiral Hill would have at his disposal 5 attack transports, 1 transport, 2 attack cargo ships, 1 cargo ship, 1 LSD, 2 APDs, 6 LCIs and 9 LSTs to carry General Watson’s Tactical Group 1, consisting of the 22nd marines and 106th regiment led by Colonel John Walker. Further support came in the form of 3 battleships, 3 heavy cruisers and 7 destroyers of Rear-Admiral Jesse Oldendorf’s task force 51.17; 3 escort carriers and 3 destroyers of Rear-Admiral Van Ragsdale task group 53.6; and Rear-Admiral Samuel Ginder’s carrier  task force 58.4. The plan was to first land two scout companies;  the Reconnaissance Company, V Amphibious Corps, against  Camellia and Canna Islands southeast of Engebi; and the scout company D, 4th Marine Tank Battalion against Zinnia Island northwest of Engebi to prevent any escape of the enemy from Engebi in that direction. The scout would secure Camellia and Canna allowing the 2nd Separate Pack Howitzer Battalion with their 75-mm pack howitzers to deploy on Camellia, and the 104th Field Artillery Battalion with their 105-mm. howitzers to deploy on Canna. The artillery would then be used to support the next day's attack against Engebi. The job of  hitting Engebi was given to the 1st and 2nd Battalions, 22nd Marines of Colonel John Walker. His 3rd Battalion would be kept in regimental reserve. The two battalions were to be supported by medium tanks of the 2nd Separate Tank Company, and a platoon from the Cannon Company, 106th Infantry, with two 105-mm, self-propelled guns. Lastly Colonel Russell Ayers’ 106th Regiment would hit Eniwetok Island; and once it was captured, the infantry would take Parry Island along with the 22nd Marines. 

Defending against them would by General Nishida’s 1st amphibious brigade; organized from the 3rd Independent Garrison Unit. It had 3 1,036-man mobile battalions, a 76-man machine-cannon unit with 6 20mm guns, 66-man tank unit with 9 Type 95 light tanks, a 243-man engineer unit, a 139-man signal unit, and 190-man medical unit. The mobile battalions had a 103-man 1st Company while the other 2 had 197 men, plus a 155-man mortar company, a 121-man artillery company with 3 75mm mountain guns, 2 37mm anti-tank guns, and a 66-man engineer platoon. These units had recently been brought over alongside his HQ.  250 IJN personnel and 1115 troops were deployed on Parry, about 692 soldiers, 500 IJN personnel and 61 men of the 61st Guard Unit would Engebi;  and only 779 troops under Lieutenant-Colonel Hashida Masahiro, commander of the 1st Mobile Battalion 

would defend Eniwetok. In the 6 weeks following the Kwajalein assault, the Japanese had been constructing defenses on the lagoon side based on reports they received from the Kwajalein attack, yet there was not enough time to make much progress. The 3 defended islands of Eniwetok Atoll had no naval-manned defenses, other than two 120mm coast defense guns and two 13.2mm twin machine-guns on Engebi's north corner. 3 75mm and 28 20mm anti-aircraft guns had been delivered, but were not even emplaced. The 1st Amphibious Brigade arrived less than a month and a half before the American would land with barely any time to dig in. While significant construction materials had been delivered, there was not nearly enough time to make much progress. Defenses would be mainly dugouts, trenches, and foxholes. The brigade deployed its infantry weapons more or less equally. Engebi was expected to be the most heavily defended, but instead the most troops were actually on Parry.

On February 15th, Hill’s scout group sailed out from Kwajalein lagoon while Operation Hailstorm smashed Truk. Meanwhile Ginder’s carriers proceeded directly to Eniwetok and on February 16th launched a series of preliminary strikes. The strike completely destroyed all the buildings upon the atoll, neutralized her airfield and destroyed 14 aircraft on the ground. Naval bombardment of Engebi, Eniwetok, Parry and Japtan Islands began in the early morning hours of February 17, and was joined by more air strikes after dawn. Simultaneously, Hill’s force arrived off Eniwetok’s southeast coast. As the surface ship bombarded the islands, amtracs launched and landed by 1:30pm against Camellia and Canna. After securing Canna and Camellia by 2pm, the Reconnaissance Company landed, against no opposition, on the 3 islands northwest of Camellia and on 2 small unnamed islands west of Canna. These landings were made to offer security to the artillery units against possible Japanese infiltration during the night.

Hill then landed his 2 artillery battalion to support the invasion of Engebi. Engebi’s total weapon strength came to 2 flame throwers, 13 grenade dispatchers, 12 light machine guns, 4 heavy machine guns, 2 37-mm. guns, 1 50-mm. mortar, 11 81-mm. mortars, 1 20-mm. automatic gun, 2 20-mm. cannons, 2 mountain guns, 3 light tanks, and 2 12-cm. coast defense guns. Colonel Yano predicted that a heavy bombardment would precede the amphibious landings, he accordingly planned to concentrate his defensive system on the lagoon shore of this triangularly shaped island. The Japanese defenders were ordered to "...lure the enemy to the water's edge and then annihilate him with withering fire and continuous attacks." Most of the prepared defenses and over half of the brigade detachment were concentrated at the center of the lagoon shore. The approach to this strong point was flanked by the fire of 2 75-mm. mountain guns on the northwest corner and 2 20-mm. machine cannon in the southern part of the concentration itself, as well as 2 37-mm. guns emplaced on the southern tip. Frontal fire could be delivered by the 20-mm. automatic guns and the three tanks, each mounting 37-mm. guns.

Hill deployed UDT-1 frogmen to first clear obstacles and mines while D Company , 4th Tank Battalion secured Zinnia and 4 other islets west of Engebi in the early morning of February 18. At 6:55 Colorado and Louisville began shelling the northern and eastern part of Enegbi. Tennessee and Pennsylvania moved at dawn to deliver close-range destructive fire against beach defenses from flanking positions on each side of the boat lanes. At 7:20 destroyers, Phelps and Hall, moved into position as direct support ships, but because of the smoke and dust rising from the island, Hall was unable to fire. Just before 8:00 the naval guns ceased fire to allow a half-hour air strike to take place. This was completed ahead of schedule and naval fire was resumed at 8:11 and increased steadily in intensity until just before the first troops landed. Shortly after the air strike was lifted, artillery on Canna and Camellia joined the naval guns and began to fire on the beaches at maximum rate until just after the first wave landed at 8:44, whereupon the artillery barrage was lifted inland to the center of the island for another five minutes. Thereafter, because of the smallness of the island, very few call missions were fired.

All of the gunfire detonated the main ammunition dump on Engebi as Colonel Walker’s amtracs made their way to the island covered by LCI gunboats. Many of the LCI rockets fell short forcing some amtracs off course, while quite a few would break down as they had been worn out by the attack on Kwajalein. Despite the technical difficulties, the first assault waves hit the beaches at 8:43. The 2nd Battalion hit Beach Blue 3 with G Company  on the left, F Company  in the center and e Company  on the right; and the 1st Battalion hit Beach White 1 with B Company  on the left, A Company  in the center and C Company  on the right. On the left, the 2nd Battalion pushed forward rapidly, bypassing isolated points of resistance and quickly overran the airfield by 10:30. F Company managed to swing towards Weasel Point on the west corner with remarkable speed. On the right, the 1st Battalion quickly split up with A Company  advancing north to New Point and C Company  towards Skunk Point on the southeast corner. 

The Japanese put up a stiff fight against them, as their spider-hole defenses on the gap between the 2 companies were covered by the dense brush and palms. As a result, the 3rd Battalion would land at Beach White 1 at 09:55 and quickly advanced with tanks to clear the various tunnels and covered foxholes that resisted them. The Japanese were slowly forced northward along the island's eastern shore, eventually becoming isolated and cut down. By 1:10, Weasel and Newt Points had been cleared; and at 2:50, about 6 hours after the initial landing, General Watson declared the island secured. 6 minutes later, C Company captured Skunk Point; and by 6:30, the 1st Battalion secured their half of Engebi. The assault had been executed so fast that even the veteran IJA defenders were unable to offer any meaningful organized resistance. Bypassed Japanese troops and infiltrators did cause difficulties through the night, but mopping-up continued and Engebi was formally secured at 8:00 on February 19. American losses were 85 dead and missing and 521 wounded against the 1280 Japanese killed and 16 taken prisoner.

 

For the assault against Eniwetok, new intelligence indicated that the island was more heavily defended than expected, so Watson would reinforce the 106th Regiment with Walker’s reserve 3rd Battalion and some Marine tanks. What they would be facing on Eniwetok was a total of 2 flame throwers, 13 grenade dischargers, 12 light machine guns, 2 heavy machine guns, 1 50-mm. mortar, 11 81-mm. mortars, 1 20-mm. automatic gun, 3 20-mm. cannons, and 3 light tanks. The Eniwetok garrison was divided into 5 forces, 3 on the lagoon shore, 1 placed so as to cut off the narrow eastern neck of the island, and 1 to be held in reserve. The 3 lagoon shore forces were to place their weapons so as to obtain interlocking bands of fire over the surface of the lagoon. The force in the east was to protect the rear of the 3 lagoon shore forces from any American units landing on the northern tip of the island. The reserve force was placed to the rear of the forces on the lagoon shore, near the western tip of the island. The defenses of the island consisted mostly of foxholes and trenches, which were better constructed and better camouflaged than those at Parry. After the capture of Kwajalein, the Japanese had begun construction of concrete pillboxes on the southwest tip of the island and had dug additional foxholes. Land mines were also found on Eniwetok.

Colonel Ayers’ new plan was to land his two battalions abreast. 1st Battalion would land on the right on Yellow Beach 2 and was charged with making the main effort to the west to clear the lower end of the island. The 3rd Battalion would land on Yellow Beach 1 and form a covering line just east of a road that bisected the island from the lagoon to the ocean shore. For the assault, the infantrymen lacked field artillery support; and although Eniwetok had also been subjected to naval bombardment on February 18, it had only received a fraction of the bombardment targeted against Engebi and Parry. A total of 1,179.7 tons of naval shells had been fired on Engebi, 944.4 tons were to be used on Parry, but Eniwetok received only 204.6 tons altogether.

At 8:10am on the 19th, carrier planes began to bomb and strafe the beaches and LCI gunboats followed this up with a last-minute rocket attack against the landing areas. Meanwhile, although the arrival of the marine tanks was delayed by choppy seas and a 9-foot embankment just inland halted the amphibian tanks, but the Americans would manage to hit the Yellow beaches at 9:16. The 3rd Battalion landed on Beach Yellow 1 with L Company on the left, K Company on the right, and I Company following as reserve. Upon landing, L Company, followed by I Company pivoted east along the pier while K Company  pushed across the island to reach the opposite coast at 10:30. On the right, however, the 1st Battalion encountered dense spider-hole defenses as C and B Companies attempted to push across the island while A Company  attacked southwest along the coast. By noon,  the front line of the 1st Battalion was in the shape of an S, extending from the lagoon to the ocean. 

The Japanese at this point made a bit of an unexpected move. As the Americans penetrated further inland, the Japanese began abandoning their positions and launched a 400 man counterattack. The Japanese managed to break through before getting completely cut down causing some havoc, but by 12:45 were beaten back. The American casualties were very high during the fight. Because of the strong resistance, Ayers ordered his 3rd battalion to attack east and for the reserves marines to land and relieve the left half of the 1st battalion's lion. The American attack to the west resumed with A Company  on the right wing making slow progress through the enemy positions near the lagoon, but the mingled elements of C and B Companies even after being reorganized and supported by 3 Cannon Company guns, could not push through the line taken up by the enemy at the end of his counterattack. Although it steadily reduced the Japanese positions, the attacking force was unable to move forward.

By 2:25, the 3rd Battalion, 22nd Marines landed, passing through Ayers’ 1st Battalion one hour later. Both battalions then launched a concerted attack towards the southwest end at 3:15, yet the Marines would soon lag behind, their advance delayed by the rugged terrain and the lack of adequate illumination and tank support. While the fight for Eniwetok was underway, the Amphibious Reconnaissance Company occupied Japtan by nightfall after first securing 10 unoccupied islets on the atoll's eastern rim while the scout tank battalion secured eight islets on Eniwetok’s eastern rim, successfully subduing the enemy resistance on Rigilli. This would allow Watson to have some much-needed artillery support for the attack against Parry.

On Parry the Japanese were able to construct very few installations and gun positions above ground in the short time that the brigade was there. With very few exceptions, the defenses consisted mostly of foxholes and trenches. These fell into two categories, the old and the new. The old foxholes and trenches were located on the ocean side, were well constructed, and often lined with rocks or coconut logs. Relying on their estimate of American amphibious tactics as demonstrated at Tarawa, the Japanese had recently undertaken heavier defenses on the lagoon side. These were freshly and hastily constructed, and therefore much inferior. All entrenchments were well camouflaged. A typical strong point consisted of a spider-web pattern of entrenchments. In the center of the web was a large personnel shelter lined and covered with coconut logs. Strips of corrugated iron and a thick layer of sand were placed over the log roof. The center was surrounded by a circle of foxholes ten to fifteen feet apart, mostly roofed over with corrugated iron. These holes were connected with one another by narrow trenches or tunnels. The trenches and tunnels on the outer edge of the web were in turn joined by radial trenches and tunnels to the shelter or control foxhole in the center of the position. The entire web was extremely well camouflaged and very difficult to locate. Parry was honeycombed with positions of this sort.

Back to the action to deny the enemy an opportunity for the customary aggressive night tactics, Ayers ordered  a night attack at 6:50. At 3:33 on February 20, Ayers’ 1st Battalion therefore managed to reach the western end of the island, though the Marines were still 100 yards to their left rear. The Japanese, meanwhile, attempted to probe and infiltrate through the night, finally counterattacking at 09:10. The 3rd Battalion, 22d Marines, found one of the main enemy defenses, manned by a strong and determined force, at the southwestern corner of the island in its zone. A combined force of light and medium tanks, 5 guns from the Cannon Company, 106th Infantry, and a supporting rifle company from the 1st Battalion, 106th Infantry, joined the Marines in destroying the enemy during the day. The 1st Battalion, 106th Infantry, mopped up its zone. The next day, after the withdrawal of the Marines, the battalion ran a line across the island from the pier and mopped up to the western end. A Company , at the right, finished first and returned to the battalion area near the landing beach. B Company , in the center, reached the end of the island a little later and then went for a swim. C Company , on the ocean side, found 22 of the enemy in hiding and destroyed them in a firefight that sent some bullets over the heads of B Companies swimmers. B Company  came out of the water, dressed, and rejoined the fight. The western end of Eniwetok Island was finally clear of Japanese. By 2:45, the stronghold was finally reduced and the western end of Eniwetok was at last secured.

To the east, Ayers’ 3rd Battalion also attempted to continue its attack during the night, but this proved futile as the troops lacked the confidence and experience for such a difficult task. As such, the battalion halted at 4:30, about a third of the way from the island's north end. They resumed their attack at 7:00 on the 21st, finally reached the north end at 4:30. The island was finally declared secure at 5:21, with the Americans losing 37 killed and 94 wounded against 800 Japanese killed and 23 taken prisoner. Because action had been bogged down at Eniwetok, the assault on Parry was delayed until the island was reduced and Walker’s 3rd Battalion could re-embark as the regimental reserve. In the meantime, aerial, naval and artillery shells had pounded Parry for three days . Naval bombardment dropped on Parry totaled 944.4 tons, considerably more than the weight delivered on Eniwetok Island; the weight of artillery shells came to 245 tons, and aerial bombs added 99 tons more. Meanwhile while the rest of the 22nd Marines were brought from Engebi to southern Eniwetok.

By this point the expedition was running low on ammunition and weapons. Naval and artillery shells were carefully apportioned. From all the ships, available grenades and demolition charges were gathered. To supplement them, 775 grenades and 1,500 percussion caps were flown in from Kwajalein while the attack was in progress. Other units surrendered BAR's and rifles to equip the 22nd Marines. In addition, the Marines had found the M1 carbine, with which many men had armed themselves, to be a less than effective combat weapon, and M1 rifles and Browning Automatic rifles were redistributed from 106th Infantry units to replace them.

For the last assault of the operation Catchpole, Walker planned was to land two battalions abreast directly against the defenders’ strongpoints; and after seizing the beachhead, tanks and infantry were to press forward to the ocean side of the island. Battleships Tennessee and Pennsylvania took positions only 1,500 yards north of the landing area and not only mauled it with their big guns but also hit it with their 40-mm. automatic weapons batteries. From the other side of the boat lanes, the heavy cruisers Indianapolis and Louisville and the destroyer Hailey also fired. Smoke and dust blew out over the lagoon without masking the target for the battleships but with serious consequences for the other three warships and for the landing craft that started ashore at 8:45. 3 LCI’s that approached through the haze with the first wave to fire rockets were hit by 5-inch shells from Hailey, killing 13 and wounding 47. Some LVTs landed outside the designated beaches, thus widening the front and making necessary the suspension of artillery fire in their vicinity. Other tractors crisscrossed or fell behind, so that the landing teams had difficulty in reorganizing on the beaches. While the tractors made their 15-minute run from the line of departure, two formations of planes bombed Parry in the last of 219 sorties made during the 6 days of action at Eniwetok Atoll. This time they only bombed the island, omitting strafing runs because of the type of defense trench systems on Parry Island.At 09:00, Walker’s 1st battalion landed at 09.00hrs on Green 1 just north of the island's central portion, with Companies B, C, and A in line left to right. It was 200yds too far south, only landing on the extreme south edge of its assigned beach.

The 2nd Battalions landed at 9.00 on Green 2 near Parry's northwest corner, but 200yds farther south than intended, with part of the battalion landing on about two-thirds of Green 3 to the south. Mines were encountered on the beach, causing some casualties. In the line were, from left to right, companies G, F, and E. The first troops struck Green Beaches 2 and 3 at 9:00, with a wave of tractors and one of LCM's carrying medium tanks directly behind them. Heavy machine gun and mortar fire greeted the marines at the water's edge. As they tried to form an assault line, enfilading machine gun fire also struck them from a concealed position on the pier at the right. The machine guns were silenced by grenades and by shells from the amphibian tanks. Then the assault passed inland. Some of the enemy in trenches and foxholes in the dune line on the beach, men who had survived the bombardment, were overcome in hand-to-hand fighting. Thankfully, shells from the amphibian tanks managed to silence the Japanese guns, which allowed the Americans to move inland and to land their medium tanks behind the battalions.

The defense plans for Parry outlined that about one half of the troops were disposed at the water's edge, where they were to be grouped into strong points about 140 feet apart. The defense of the beaches was to be supported by mountain guns, 20-mm. automatic guns, and other weapons. The mountain guns and 20-mm's were to fire first. Light and heavy machine guns were to fire on landing craft before and after they reached the underwater obstacles. Next, mortars and grenade throwers were to deliver concentrated fire against the enemy at the beaches and were to cover the sectors between fortified areas and strong points. To facilitate the employment of artillery and heavy weapons, the order called for fields of fire to be cleared through coconut groves. The order gave quite explicit instructions for measures against tanks: "Destroy enemy tanks when they are stopped by obstacles by means of hollow charge anti-tank rifle grenades, close-in attack, land mines, water mines, and Molotov cocktails. Especially at night, have a part of the force attack them." The order made it very clear that the brigade was not expected to survive an American assault once it had established a beachhead. Any troops remaining after the Americans had landed in force were to assemble in a central area. Then, the order continued, "...sick and wounded who cannot endure the battle will commit suicide. [Others]... will reorganize, return to battle as a unit, and die fighting.”

3 dug-in Japanese light tanks decided to attack, rather than earlier when the infantry were vulnerable. Yet the Shermans immediately destroyed them before they inflicted any damage, so Walker’s battalions would be allowed to push forward against the retreating enemy. While Companies G and F swung left to reach the north end by 1:30, E Company  drove straight across to reach the ocean shore by 12:00. Then, as the Marines were consolidating, a group of 200 Japanese were discovered marching north and were wiped out within minutes.

Over on the right, B Company reached the ocean coast at 11:55, while Companies C and A swung south and  successfully reached Valentine Pier by 1:30. Walker’s reserve 3rd Battalion  landed at 10:00, immediately advancing south while clearing bypassed enemy pockets. After artillery bombardment, the attack south was launched at 1:30. Pressing through thick underbrush, both battalions achieved rapid progress as they overran a series of trench and foxhole defenses. The battalions were 450 yards from the island's southern tip when they halted for the night.Walker decided to declare the end of enemy resistance at 19:30, radioing Brigadier General Walker, "I present you with the island of Parry at 7.30."

The Only slight enemy activity that existed anymore was occasional sniping, which would be swiftly cleared by 09:30 on February 23. For the capture of Parry, Marine casualties were 73 dead and missing and 261 wounded against 1300 Japanese killed, including General Nishida, and 66 captured. In total, American casualties during the Battle of Eniwetok came to 313 killed, 879 wounded and 77 missing. The Japanese had lost their entire garrison, with 3380 killed and 105 captured. Between March 7 and April 5, Walker would then conduct Operation Flintlock Jr., carrying 29 successful landings, securing 14 mostly unoccupied atolls and killing over 100 Japanese at the cost of two Marines killed. Other detachments would finally occupy the Erikub, Aur and Ujelang Atolls by the end of April, leaving only Mille, Maloelap, Jaluit and Wotje bypassed and unoccupied, in addition to the Japanese presence at Kosrae, Wake and Nauru. 

Over on Jaluit Rear-Admiral Masuda Nisuke commanded the 13,000 personnel and beginning on March 4th, the 4th Marine Base Defense Aircraft Wing, headquartered on Majuro, and the 7th Air Force commenced a concerted campaign to neutralize the Japanese garrisons, which continued until the war's end. Navy Aviation and Army Air Forces had previously destroyed most Japanese aircraft on these islands. The 13,000 tons of aerial-delivered ordnance, coupled with frequent naval shelling, killed 2,564 Japanese and 4,876 died of disease and starvation; the Marines sprayed oil over the garrisons' gardens. Fighter-bomber units deploying to the Pacific would first serve in this role, perfecting their bombing techniques before moving forward to support other operations as new units replaced them. The Japanese survivors would finally surrender on September 2, 1945.

As the American commander took stock of what they had achieved in the Marshalls, their confidence and self-assurance rose to new heights. In less than 3 months’ time, the tragic and costly lessons of Tarawa had been refined and integrated into amphibious planning and doctrine, and the results had been tremendous. To the extent that further improvement was needed, it was in the details of execution rather than any deficiency in the plans themselves. Holland Smith concluded in his final report, “In the attack of coral atolls, very few recommendations can be made to improve upon the basic techniques previously recommended and utilized in Flintlock.” Over in Tokyo there was shock and incomprehension at the speed and ‘low cost’ of the US victory over the Marshall Islands. The implications for Japan’s future were dire. As Ichiro Koyose, the permanent Director of Japan’s Imperial Rule Association said in an address, “The Marshall Islands are the frontporch entrance to Tokyo … The enemy is probably finally thinking of some such thing as bombing Tokyo in deadly earnest …” Yet that is it for today on the Marshall Island front as we are going to be diving back into Burma.

The Japanese had launched their main offensive on the Arakan at the start of February, successfully infiltrating through the British positions to cut off their rear. By cutting the Indians' supply lines off, the Japanese expected to force them back into disarray; but these were not the same men they had been fighting for years. The Indian troops were better trained and ready to put up a real fight. This was seen when they faced Japanese attack after attack, using their all-round defensive brigade boxes, also referred to as "baby tortoise" or "beehive" tactics. This baffled Japanese,and soon they would leave the invaders effectively encircled and running out of supplies, as they themselves depended on what supplies could trickle to them over jungle trails. With increasing 'fanatical' desperation, the Japanese  began to press home attacks seeking to secure vitally needed stockpiled supplies of food, arms and ammunition upon which their offensive depended. In the Sinzweya area, the 112th Regiment made a night attack on the 9th, successfully breaking through the southwest corner of the enemy's perimeter defense in the Sinzweya Basin. Although the Regiment was successful in firing an ammunition dump and doing great damage, the enemy's employment of tanks forced it to draw back without further exploiting the breakthrough. On the morning of the 10th, Major General Sakurai met Colonel Tanabashi on Hill 315, due northeast of Sinzweya, and encouraged him to press the enemy more aggressively. The failure of the 112th to achieve a signal success appeared, however, to have so depressed morale that the Regiment was reluctant to repeat its attack.

The 7th Indian Division, kept its morale high despite the intense fighting, rapidly mounting casualties and increasing exhaustion. They continued to fight on until the advanced Japanese units had exhausted their own food and ammunition. Whenever possible, the British-Indian troops also struck back against Japanese positions and harried their already tenuous supply lines. Furthermore, the massive firepower of the British mountain, field and medium artillery inflicted massive casualties on the attacking Japanese infantry. Firing from positions within each brigade box, carefully concerted artillery fire plans thus rained death upon Japanese troops scattered in the jungle throughout the divisional area. As such, the 71st Brigade would successfully recaptured Taung Bazaar on February 10, and was steadily advancing southwards towards the Ngakyedauk Pass.

That same day, General Giffard realized that there was no possibility of 15th Corps being able to reach the Indin-Rathedaung line before the pre-monsoon swell made amphibious operations impossible, so he recommended canceling the Akyab assault. He placed the 36th Indian Division under the 14th Army, allotted the 50th Brigade to 4th Corps and ordered the 25th Indian Division towards Chittagong. General Slim, however, realized that the Japanese plans had miscarried, so he directed General Christison to resume the offensive against the Tunnels-Buthidaung position as soon as he had cleared the land communications to his forward divisions. 

 

Consequently, as the 29th Brigade of the36th division was arriving at Bawli, Christison sent the bulk of the 26th Indian Division to destroy the enemy in the Kalapanzin valley behind the 7th Division. By the13th, patrols from both divisions successfully linked up near Taung Bazar; but at the same time, the Japanese were bringing reinforcements for their attacks at Sinzweya. The Japanese offensive reached its climax on February 14 when General Sakurai called for an all-out attack that evening. The attack was courageous and managed to achieve some initial gains, but it was also uncoordinated, suicidal and unsuccessful, ending with the Indians reinforcing the Admin Box the following day. Meanwhile elements of the 5th Indian Division, regrouped and battered away against a heavily fortified Japanese roadblock at the summit of the Ngakyedauk Pass. Thus, the Japanese tactical and administrative position quickly went from bad to worse around Sinzweya, as pressure steadily mounted against its vastly outnumbered troops.

After a few days of bitter fighting the Japanese finally abandoedn their positions at Kyaukyit and Pyinshe Kala and began occupying areas covering the routes back to their main positions.  By the 20th, the strength of the Japanese striking force had  shrunk to 400 men increasingly-debilitated by lack of sleep and shortages of food. On the 23th, after a short but sharp fight, a battalion of 89th Brigade from the east and 123rd Brigade from the west linked up at Ngakyedauk Pass and by evening had firmly secured it. The following day, as soon as the 500 casualties from Sinzweya had been evacuated, the pass was opened to normal traffic and air supply of the 7th Division ceased. As Geoffrey Evans later wrote with obvious pride: “For eighteen days the British and Indian troops, most of them belonging to the administrative services, had withstood the determined attacks of trained Japanese infantry supported by guns and air. It spoke volumes for the war in which the junior leaders had carried out their task and the stout-heartedness of their men.”

At this point, General Hanaya recognized the inevitable and ordered the Ha-Go offensive to be abandoned. The shattered remnants of Sakurai’s command subsequently withdrawing in small parties. The last attack on Sinzweya, made on the 22nd, ended in failure. On the following night, acting on his own responsibility, Colonel Tanabashi withdrew his main force to Kreingyaung, leaving the 8th Company of the 112th Infantry at Ngakyedauk Pass and the 2nd Battalion of the 112th on a small hill south of Sinzweya. Upon receiving a report of Tanabashi's withdrawal, Major General Sakurai was really pissed off but realized that the move was undoubtedly inevitable, being forced by lack of food and supplies. At the suggestion of General Sakurai, the Division commander determined to suspend the offensive and ordered the Sakurai Unit to withdraw to the line of the Buthidaung-Maungdaw Road. Moving units into the line to cover the withdrawal, the movement south began on the night of 24 February and was completed by 1 March. The 1st Battalion of the 213th Infantry, which had been holding positions in the vicinity of the road between Ngangyaung and Maunghnama since 6 February, left its positions on the night of the 25th and, after breaking through the enemy lines, returned safely on 3 March.

Many units were trapped, however, between units of the 26th and 36th Divisions advancing from the north and 5th Division from the east through the Ngakyedauk Pass upon the anvil of the boxes. In the end, the Battle of Ngakyedauk Pass cost 15th Corps 3506 casualties, but it also marked the turning point in the Burma Front. The Japanese lost 3106 killed and 2229 wounded, in what would be the first time that they met well trained British-Indian formations in battle and the first time that their enveloping tactics, aimed at cutting their opponents' line of communications, failed to produce the results they expected. Not only had operation HA-GO been an abysmal failure, but it materially undermined the Japanese ability to resist further British attacks. By March 5th, the 15th Corps had completely recovered and resumed its own offensive against the now disorganized and weakened Japanese forces in Arakan. Although the Japanese staged a remarkable recovery and still offered dogged resistance, the 5th Division would capture Razabil on March 12th and the 7th Division would seize Buthidaung and later mop up the Letwedet Fortress in late March.

The battle in the Marshalls absolutely shocked the Japanese in its speed, efficiency and low cost for the American forces. Now the Japanese feared the Americans would soon be in range to hit the home islands with their dreaded bombers. In the Burma Front, the former Japanese super soldiers were now realizing the Indian Army could no longer be pushed around.

- 117 - Pacific War - Operation Hailstone: the Smashing of Truk , February 13-20, 1944

Last time we spoke about Operation Flintlock, the invasion of Kwajalein. The Americans had unleashed an incredible amount of air, sea and land forces against the Marshall Islands. The amphibious invasion of most of the islands saw little resistance, but on Kwajalein they would meet a determined enemy. The Americans achieved strategic surprise; artillery preparation, naval gunfire, and aerial bombardment had successfully softened up the target in a fashion unexcelled at any other time in the Pacific War; the ship-to-shore movement had been conducted expeditiously and without too many hiccups; supplies flowed ashore and to the front lines relatively smoothly and without interruption; the infantry-engineer teams assisted by tanks moved steadily clearing the enemy from shelters and pillboxes; and American casualties had been fairly light. Altogether, the battle for Kwajalein represented the ideal for all military operations. Then we covered a bit of the Burma front where the allies unleashing an offensive, while the Japanese unleashed Operation HA-GO.

This episode is Operation Hailstone: the Smashing of Truk

If you are still hungry for some more history related content, over on my channel, the Pacific War Channel you can find a few videos all the way from the Opium Wars of the 1800’s until the end of the Pacific War in 1945. 

For those who came rushing over to see the scene at Kwajalein descriptions given were comically noted as “a hell of a Spruance Haircut, with some Mitscher shampoo”. Looking down at Roi and Namur a F6F pilot recalled “ it looked like “the moon,” or “plowed ground.” The beach and roads were strewn with the charred and misshapen remains of equipment, tanks, and armored vehicles. I don’t think there was a stick of anything standing. It looked just completely beaten up.” A sailor who visited one of the captured atolls had observed “palms were shredded where shells and bomb fragments had made direct hits, leaving stumps that looked like old-fashioned shaving brushes stuck, bristles up, in the sand”. Holland Smith was greatly annoyed by the number of sightseers who came to Kwajalein stating. a “regular tourist haunt. . . . The big army and navy brass from Pearl Harbor descended on us like flies. The photographers had a gala day snapping pictures against the background of shelled buildings, while visiting brass hunted for samurai swords and other souvenirs.” 

Meanwhile a single battalion was assigned to capture Majuro, and their battle would consist of walking up some beaches completely unopposed. The Japanese garrison had pulled out a week earlier. Admiral Hill declared the atoll secure only 2 hours after landings were made. Its huge anchorage would accommodate all the mobile floating logistical assets of Service Squadron 10 and for the time being became the principal advance base for the 5th fleet. Jaluit, Mille, Wotje and Maloelap, which had sizable Japanese garrisons, would not be invaded by the Allied forces. Since the Japanese were cut off from outside assistance, the garrisons were doing no harm to the Allied effort, so they would be left alone, thus saving many American and Japanese lives by not forcing the issue. 

But Eniwetok Atoll would not be bypassed, because she held the second largest lagoon in the Marshall Islands. As Admiral Nimitz and his commanders considered the repercussions of their surprising quick and low cost victory, they soon elected to accelerate the schedule of future operations in the region. Eniwetok had been originally slabbed for May, but it seemed obvious the Japanese power in the Marshalls was crumbling a lot faster than anticipated. Consequently, Admiral Nimitz knew it would be necessary to capture the atoll to give shelter to all the ships he intended to deploy westward in the drive against the Japanese inner empire. Since it now seemed Brigadier-General Thomas Watson’s 8000 reserve troops of the 22nd Marines and the 106th Regiment would no longer be required, Admirals Spruance and Hill began preparing them for the invasion of Eniwetok. However Eniwetok was within Truk’s air combat radius, thus to hit Eniwetok, they would first have to neutralize what was called the Gibraltar of the Pacific, Truk.

Prior to WW2, Truk was neither well developed nor well defended. Although the US feared the Japanese had been fortifying Truk for nearly two decades; in truth, the Japanese largely ignored Truk after capturing it during WW1. When the Pacific War started on December 7, 1941, only a few coastal batteries and naval minefields added since November 1939 covered the passes into Truk Lagoon. Few other defenses, including inadequate anti-aircraft artillery, protected it. To the US Navy, Truk appeared impregnable and sailors spoke the name in awe‑struck tones. This was because Truk needed few artificial defenses to make it virtually impregnable to surface invasion. Truk was a naturally sheltered and easily defended anchorage, large enough to accommodate the entire IJN and out of range of enemy naval guns. Their defense, however, depended on the air garrison, one of the strongest in Japan’s Southeast Pacific theater. Dangerous long‑range reconnaissance flights flown by B‑24s from bases in the Gilberts in December 1943 managed to bring back photos that allowed intelligence officers to map out the air bases and the various anchorages in the lagoon. Analysts thus began to realize there was not as much there as expected. And thus Operations Catchpole and Hailstone were born. Catchpole would be the invasion of Eniwetok while Hailstone would be the neutralization of Truk and as a secondary objective, to discern if Truk could be bypassed similarly as Rabaul or Maloelap  was.

Operation Hailstone would be bigger than December’s raid against Kwajalein. Vice-Admiral Raymond Spruance’s 5th fleet would deploy Task Group 50.9 and three of Task Force 58’s four fast carrier task groups. Task Force 50 was under Spruance himself while Admiral Mitscher had command over the carrier task force. Spruance would also had overall command over the operation. Fleet carriers Enterprise, Yorktown, Essex, Intrepid, and Bunker Hill and light carriers, Belleau Wood, Cabot, and Monterey would be launched aircraft in the operation. Admiral Lea would control a fast striking force consisting of light carrier Cowpens, and battleships Iowa, New Jersey, Massachusetts, Alabama, South Dakota and North Carolina. 10 submarines would be lurking like sharks around Truk independently seeing if they could possibly intercept some IJN forces or rescue down US pilots during the attack. To prepare for the operation, on February 4th a lone PB4Y Liberator launched off Torokina’s airfield to carry out reconnaissance of Truk. The photos indicated that Truk Lagoon held a battleship, two aircraft carriers, six heavy cruisers and four light cruisers, 20 destroyers, and 12 submarines. The PB4Y was spotted and fired on by warships in the harbor and several fighters were launched to intercept, but only one, a floatplane fighter, came close enough to open fire. The pilot managed to high tail it out of there safely. 

The American reconnaissance flight alerted Admiral Koga that they could expect a heavy raid at any moment, so he ordered all his warships to depart the lagoon before February 21st, the date they predicted the Americans would hit. The departure was extremely hasty. 2 auxiliary aircraft carriers had just arrived at Truk the previous month. When the departure order came, they haphazardly unloaded their aircraft in order to leave quickly. The aircraft were left parked nose-to-tail on airport aprons and taxiways. Cargo ships equally hastily unloaded stores so they could leave. Fuel barges were drained to top off the tanks of the Combined Fleet’s major units. They had to be tediously refilled from tankers, a task made difficult by choppy seas kicked up by rough weather between February 13 and 15. On February 12, most of the Combined Fleet’s major units left Truk for Palau. The light cruiser Agano, previously damaged and under repair, could not depart until February 16. Its departure was so late that it would be caught and sunk by the newly arrived US submarine screen. Other ships were still preparing to leave, their departure delayed by bad weather and slow refueling.

Of those ships trapped still at Truk were the 4th fleet of Vice-Admiral Kobayashi Masami, consisting of light cruiser Naka; destroyers Maikaze and Oite, alongside some units of the 8th Fleet and several transports. There were also various auxiliary, destroyer, repair ships, transports and the 6th Fleet of Vice-Admiral Takagi Takeo headquarters. On February 5th, Admiral Hill learnt he would be commanding the Eniwetok expeditionary forces and have less than two weeks to prepare them. Moving up the invasion of Eniwetok required stripping the new garrisons of Kwajalein and Roi-Namur of manpower and supplies. The landing boat crews were green and had no real training with the troops. As recalled by General Watson “the infantry, amphibian tractors, amphibian tanks, tanks, aircraft, supporting naval ships, and most of the staffs concerned had never worked together before.” Yet we will be talking about Eniwetok in the next episode so we will be diving straight into Hailstone.

Operation Hailstone had been long on American drawing board. On December 26, 1943, Admiral Nimitz had informed King that he thought the operation would become feasible by the following April, but he pledged to do it earlier if circumstances allowed: “Much depends on extent of damage inflicted on enemy in all areas in next 2 months.” Located 669 miles southwest of Eniwetok, Truk was a colossal atoll, it held a cluster of around a dozen islands near the center of its lagoon. Around 2000 Micronesian natives lived on the islands, mostly in thatch huts on grassy plains and beaches. There was a sense of dread amongst the aviators and crewmen of the task forces assigned to the operation. They were to attack the “mystery base”, Truk had acquired a reputation as an unassailable fortress. It was thought to be a major hub of Japanese airpower, defended by hundreds of crack pilots in Zeros. The task forces sortied westward on February 12th and no Japanese would bother their approach. The carriers got to their assembly point 90 miles northeast of Dublon before sunrise on February 17th. AT 4:43am the operation kicked off when 5 fleet carriers launched 72 Hellcats to go knock out the enemy air power prior to sending in the bombers. This was a new technique Admiral Mitscher had concocted himself. The Japanese were caught completely unprepared, no Japanese aircraft were in the air when radar picked up the incoming aircraft. The IJN's 22nd and 26th Air Flotilla's were on shore leave and their radar had difficulty detecting low flying aircraft, a weakness allied intelligence exploited. Despite this, the Japanese tossed 90 aircraft, half of which attempted to intercept the US fighters without coordination. 

Within minutes of combat, 30 Japanese fighters were shot down, by the end of the engagement a total of 55 would fall. The Americans lost 4 Hellcats, and at least one according to VF-6 pilot Alex Vraciu was a victim of friendly fire. “There were dog fights all over the place. I even saw one of our Hellcats shoot another Hellcat down. It was a great deflection shot but . . . one of our guys just shot first before being sure and this other poor pilot was forced to parachute out. In the course of the action, I saw a number of Japanese parachutes in the air.” The American pilots had expected to be facing 200 Japanese aircraft. According to estimates given in postwar interrogations, the Japanese had 68 operational airplanes on the Moen field; 27 on the Dublon field; 20 on Eten and 46 on Param, for a total of 161. Parked on the big field at Eten were some 180 aircraft that were damaged, most grounded for lack of spare parts, or immobilized for lack of aircrews. Most of these would be destroyed on the ground. Although Admiral Koga anticipated the American move against Truk, air and naval forces were not on the alert when the American planes suddenly appeared overhead. According to Masataka Chihaya, a staff officer with the 4 Fleet, the pilots, ground personnel, and ships’ crews had been kept in 24hr readiness since the overflight of the 2 marine PB4Ys two weeks earlier, and had reached a state of collective exhaustion.

Another factor to the catastrophe was that of morale and even discipline had eroded since the withdrawal of the heavy warships. Pilots had refused to climb into their cockpits when ordered, many had gone absent without leave. The atoll’s commander, Vice Admiral Masami Kobayashi, had apparently concluded that the American fleet was still engaged in the Marshalls, and authorized a downgrade in the alert level. On February 16, many pilots and other personnel had left their barracks for R&R. The morning of the American raid found a large proportion of Truk’s aviators asleep in the atoll’s largest town, on the island of Dublon, having partied pretty hard into the night at local drinking establishments. Their only means of returning to their airfield on the island of Eten was by ferry, and the ferry could not accommodate all of them at once. Many aircraft, both on Eten and on the airfields of Moen and Param islands, had also been disarmed and drained of fuel. Kobayashi’s ignominious failure to keep his forces on alert put an end to his naval career; he was relieved of command and then forced to retire from active service.

Having swept the skies of opposition by 6:00am, the Hellcats began strafing the seaplane base at Dublon and the airfields on Moen, Eten, and Param, successfully destroying another 40 aircraft on the ground. As the fighter sweep was ending, 18 Avengers emerged dropping their payloads onto the airfields,  neutralizing Truks air power. As such, the living hell created by strafing and bombs saw a total of 125 operational aircraft and 110 air arsenal aircraft get destroyed or seriously damaged on the ground. With Truk’s air power neutralized, the next American objective was to hit the shipping in the lagoon, so the carriers then began launching full deckload strikes, staggering the launches so that there were aircraft over Truk virtually continuously for the rest of the day. James D. Ramage, flying a VB-10 Dauntless, noted that several Zeros flew by him without offering combat. He assumed that they were dispirited by the one-sided results of the air fight and were determined to survive it. It was a syndrome that had become increasingly common during the later stages of the South Pacific air campaign. 

Due to the lack of air cover or warning, many merchant ships were caught at anchor with only the islands' anti-aircraft guns for defense. At 07:30, the first shipping began to be attacked. Yorktown’s bombers rapidly sinking the cargo ship Fujikawa Maru and then bombing the submarine tender Rio de Janeiro Maru was hit by 1,000lb bombs dropped by Yorktown SBD Dauntlesses east of Uman. It stayed afloat, but sank the next day. Another submarine tender, the Heian Maru, headquarters of Vice-Admiral Takagi Takeo was hit twice , but the ship would successfully survive the relentless American attacks, then offloading Takagi on Dublon after sunset. By 9:23am, Lee’s battleships, heavy cruisers and destroyers came in to try and catch escaping ships. Some Japanese vessels attempted to flee via the atoll's North Pass; but were bottled up by the aerial attack and by Lee’s warships, most of them would be successfully sunk by 13:00. 

The famed marine fighter ace Major Gregory “Pappy” Boyington, of the Black Sheep squadron VMF-214, had been shot down and captured off Rabaul a week before Hailstone. Alongside other POW’s he was flown into Truk while the raid was developing. As the Betty bomber carrying them rolled to a stop, Pappy and his fellow prisoners were thrown out onto the airstrip. They looked up and were shocked to see an F6F Hellcat flying low over the airfield, walking .50-caliber fire across  parked planes. The bomber from which they had just been ejected went up in a sheet of flame. The Americans were shoved into a pit by the side of the airfield, and watched the action overhead and cheered for the attackers. Pappy recalled this “There was so much excitement I couldn’t do any differently. I just had to see those Nip planes, some of the light planes like the Zeros, jump off the ground from the explosion of our bombs and come down “cl-l-l-lang,” just like a sack of bolts and nuts. The planes caught on fire and the ammunition in them began going off. There were 20-mm cannon shells and 7.7’s bouncing and ricocheting all around this pit. Some of these hot pieces we tossed back out of the pit with our hands”.

Enterprise dive-bombers dropped 1,000-pound armor-piercing bombs on targets chosen from the aerial photos taken earlier. The planes hurtled down through flak bursts and smashed the stationary ships. A bomb hit the stern of the 13,000-ton Hoyo Maru. The 7,000-ton aviation stores ship Kiyozumi Maru and lit her up. A VT-6 Avenger flew low over the ammunition ship, the Aikoku Maru, and landed a bomb dead-center amidships. The target went up in a huge, rolling ball of flame that engulfed the plane and destroyed it. The shockwave was powerful enough to rock Lieutenant Ramage’s aircraft, more than 2,000 feet overhead. “It was, I think, the biggest explosion I’ve ever seen, other than the atomic bombs. It was just an enormous blast.” 5 ships managed to escape the carnage within the lagoon. The light cruiser Katori, auxiliary cruiser Akagi Maru, destroyers Maikaze and Nowaki, and the small trawler, Shonan Maru. Unfortunately for them they ran directly into Lee’s force at 1:30pm. Only the destroyer Nowaki managed to outrun the Americans as she fired a spread of torpedoes trying to keep the Americans at a distance.

Spruance was ultimately the one who ordered the surface ships to come into the combat area and this resulted in close calls for friendly fire. Mitscher would continuously order pilots to hold back their payloads against fleeing ships and wait for identification first. Many of the aviators would accuse Spruance of seeking to have “the big guns” get their taste of the blood. But the big guns would basically only finish off some crippled ships. Minneapolis and New Orleans sank two immobilized ships with 3-4 salvos. Meanwhile the USS New Jersey nearly took two torpedo hits from a sinking IJN destroyer. American ships came to the ailing IJN vessel trying to pick up survivors, but almost all the Japanese sailors took their own lives. The Iowa would take a bomb hit from a Japanese aircraft, but suffered little damage. If one or more of the American surface ships were hit by torpedoes, it may have very well cost Spruance his command. The ordinarily conservative fleet commander had behaved with impulsive bravado, and it seems for no better reason than a blackshoe’s inborn desire to claim a piece of the action for the big guns. Admiral Sherman’s tactful conclusion was that “this expedition accomplished little and only complicated the attacks by the carrier planes.” Lieutenant Ramage was less gentle: “So the big battleships finally drew blood against a cruiser that was almost dead in the water. It must have been a great victory.”

The death toll for the first day of Hailstone was more than 20 Japanese ships sunk, but the fun was not over. 6-7 Radar-equipped B5Ns capable of tracking ships at night launched perhaps from Rabaul or Saipan, hunting for the US carriers. They were spotted on radar as they approached the US ships. Night fighters attempted to intercept them, but were unable to find them in the darkness. The task force maneuvered to avoid the incoming bombers, which would have worked if the Japanese were using aircraft blindly flying a standard search pattern. However, the radar-equipped Nakajimas detected the course change and continued to home in on the carriers. Between 7:00 and 10:00, the aircraft made several approaches to the US ships, but were kept at a distance by heavy radar-directed anti-aircraft fire. The Yorktown launched a night fighter F4U Corsair at 9:20 to intercept a particularly persistent Nakajima, vectoring the fighter towards the torpedo bomber. But for once, the Japanese used radar to better advantage than the US, so the Corsair never made contact with the Nakajima. The Nakajima was then able to press its attack, launching a torpedo at the USS Intrepid. It struck near the starboard quarter, jamming the rudder, killing 11 aboard, and wounding 17. The B5N that dropped the torpedo apparently escaped unharmed. Intrepid was in no danger of sinking, but made her way to Majuro to be safe.

The Americans then launched their own night attack on Japanese shipping in Truk Atoll. At 2:00 am, the USS Enterprise launched a flight of 12 radar-equipped Avengers to attack the surviving Japanese ships in Truk Lagoon. Each aircraft was armed with 4 500-pound bombs. The concept of performing a low-altitude night attack, with the planes guided to the targets by radar alone, had been studied and discussed but never attempted before. It required the pilots to navigate to Truk on instruments alone. Once over the lagoon, they circled over the anchorages until radar echoes provided an image of the targets. The mission would be a tactical breakthrough, unprecedented in the annals of aviation or naval history. Lieutenant Commander William I. Martin, who trained the airmen, recalled “Radar displays at that time required an operator to do a great deal of interpreting. It was like learning a new language. Instead of it being a polar plot, looking down on it like a map, the cathode ray tube just gave indications that there was an object out there. After considerable practice, a radar operator could determine that there was a ship there and its approximate size. You related the blip on the radar scope to the image of the ship”. In about 30 minutes, the Avengers made 25 passes over Dublon and Eten, scoring 13 direct hits on ships, two on rocky islets mistaken for ships and seven near misses. As a result, around 12 vessels were sunk during the attack, including the Heian Maru. It was a remarkable performance by a dozen aircraft in the US Navy’s first carrier-launched night attack. 

The following dawn, Mitscher sent another fighter sweep, though it would not be very effective as the Japanese had basically no surviving aircraft in the area. 200 aircraft \ met negligible air opposition over the atoll as they worked over the remaining targets at their leisure. Hundreds of incendiaries were dropped on smoking airfields, parking areas, and hangars. The bombers paid special attention to the fuel tank farms, which had been spared on the first day in order to prevent smoke from obscuring visibility. By noon, Japanese resistance was almost non-existent and there were no more worthwhile targets, so Spruance and Mitscher decided to call a halt to the attacks, as it was considered that Truk no longer posed a threat to the Eniwetok invasion. 

Hailstone cost the Americans 12 fighters, 7 torpedo bombers, 6 dive bombers and 2 floatplanes. 29 aircrew died; and 28 sailors died aboard the Intrepid. The operation had been one of the most smashing carrier raids of the Pacific war. Though most of Japan’s heavy naval units had fled the lagoon, the Americans had sunk three light cruisers, four destroyers, three auxiliary or training cruisers, and six other naval auxiliaries. In addition, around 30 merchant ships were sent to the bottom of the lagoon, including 5 precious oil tankers. The total shipping losses approached 200,000 tons and many of those vessels had been laden with munitions and other supplies that could not be recovered. 17,000 tons of fuel went up in the attack, at a time when fuel was running very short for the Japanese. The Japanese lost 249 aircraft, most on the ground. As Rear Admiral Samuel Eliot Morison would later write, “Courage and determination the Navy had shown from the first, but in the Marshalls it demonstrated mastery of the art of amphibious warfare; of combining air, surface, submarine and ground forces to project fighting power irresistibly across the seas. The strike on Truk demonstrated a virtual revolution in naval warfare; the aircraft carrier emerged as the capital ship of the future, with unlimited potentialities.”

The IJN Combined Fleet would never return to Truk; the 4th Fleet headquarters remained at Truk, but its warships left; and the transports carrying the 52nd Division to Truk, some of which had arrived on February 19, hastily unloaded and quickly departed. Vice-Admiral Kobayashi Masami was held responsible for the defeat and would consequently be relieved of his command, never to return to active duty. But that's it for the Marshall Islands campaign for now as we are shifting over to the south pacific. 

In preparation for the invasion of the Admiralty Islands, the allies first would need to seize the Green islands, situated 117 miles southeast of Rabaul. Admiral Halsey had been tasked with landing General Barrowclough’s 3rd New Zealand Division consisting of the 14th Brigade; Special Army Tank Squadron; 17th Field Regiment; 29th Light Anti-Aircraft Regiment; 144th Independent Battery; 53rd Anti-Tank Battery; 967th Coast Artillery Battalion; Naval Base Unit No. 11 and other supporting units. Halsey assigned Admiral Wilkinson to command the operations. He would transport the men in 3 echelons using a plethora of Destroyers, Destroyer Transports and countless landing crafts. AirSols would be providing coverage alongside Admiral Merrill’s Task force 39 consisting of light cruisers Cleveland, Columbia and Montpelier; and destroyers Charles Ausburne, Dyson, Stanly, Spence and Converse. There would also be Admiral Ainsworths Task force 38.

Wilkinsons echelons departed Vella Lavella and the Treasury islands On February 12th and 13th. They met near Bougainville and together advanced towards the departure line off Barahun Island. The Americans expected Rabaul’s airforce to be greatly depleted by this point, but the convoy was still harassed by 15 Vals and 17 Zeros during the night of February 14th. 10 vals managed to score a hit and 3 near misses against cruiser St Louis, killing 23 men and causing moderate damage. The bombers also tried attacking the landing craft, but apart from a near miss on LST-446, the landing would proceed quickly and smoothly. The landing craft began taking off on the morning of February 15th as AirSols fighters gained air supremacy over the skies of Nissan Island. 32 fighters form Squadron 14, RNZAF, commanded by Squadron Leader S. G. Quill, and Squadrons 1 and 18, commanded by Squadron Leader J. A. Oldfield, both kept 18 aircraft continuously over the island until dusk, flying sorties from the airfields at Empress Augusta Bay.  12 Japanese bombers would be reported shot down. This was the last air opposition encountered during Operation Squarepeg. With such a numerous  fleet sending thousands of troops ashore with impunity only 115 miles from Rabaul proved AirSols was a force to be reckoned with. Ferried ashore in LCIs and LCVPs, into the lagoon in southern Barahun Island, the troops would disembark at several landing beaches around the Pokonian and Tangalan Plantations. 

Within just 2 hours, about 5800 New Zealanders were ashore. Patrols were then sent out, and carrying parties began moving stores off the beaches further inland. As the beachhead was established, there was only a brief resistance from several Japanese barges around Sirot Island, before a perimeter was established. By nightfall, in addition to the aforementioned troops, Wilkinson had also landed 58 jeeps, 67 trucks, 44 guns, 8 Valentine tanks, 426 tons of petrol in drums, 2000 gallons of fresh water in tins, and 267 tons of rations. The following day, as the Kiwis fanned out along Nissan Island, about 21 Japanese were encountered on Sirot. Late that afternoon, natives reported that an unspecified number of Japanese had taken refuge on the densely wooded island of Sirot, and the task of clearing the island was assigned to B Company, led by Captain D. Dalton. The Japanese were swiftly dealt with, but the Kiwi’s would suffer 5 deaths and 3 wounded in the firefight.

On February 18, patrols from the 37th Battalion reached the northern tip of Nissan Island and reported it clear while the 30th and 35th Battalions dealt with a large group of Japanese at the south point of the island. The Kiwis accidentally came upon the remaining Japanese garrison on 20 February, in an area previously declared clear by patrols. It was along the coast near a few deserted native huts passing as the village of Tanaheran on the map. On February 19, the remaining 100-man Japanese garrison signed off on their radio ‘We are charging the enemy and beginning radio silence’.The Kiwi’s suffered 3 deaths and 11 wounded. The Japanese had been overwhelmed and annihilated. The next day the second echelon of Admiral Fort arrived. Organized resistance had ceased. In total, 120 Japanese had been killed against the 13 killed and 24 wounded of the Allied forces. 

With the Green Islands under their control, the Allied forces now needed to do something about the 1200 friendly native Melanesians whose taro gardens and coconut groves were about to be turned into airfields. The answer was a temporary evacuation to Guadalcanal. This was explained to the natives' head men, and, as the Melanesians are born rovers, the prospect of a boat ride to the Solomons and free food there was highly pleasing. Accordingly, "Grandpa" Roger Cutler's LSTs of the Second Echelon took on the function, new even for Love-Sugar-Tares, of evacuating natives; and so well was this done that by the time the flotilla of Melanesian Mayflowers reached Guadalcanal the 1147 embarked had increased to 1148. The Green Islands would prove to be a very useful link in the strangling of Rabaul, with a PT base immediately opening on February 17 and with a new fighter strip being completed by March 4, which for the first time put Kavieng within range of AirSols fighters and bombers. But now we have to shift over to the boys in New Guinea.

The last time we were in New Guinea, the Australians were in hot pursuit of General Nakano’s men. On February 3rd, the 30th battalion of Lieutenant-Colonel William Parry-Okeden had set off from Singor to take over for the 4th battalion at Crossington. The next day, the Australians reached Nemau and the day after that established a new supply beach at Butubutu. On that same day orders came in stating all commanders must make every endeavor to capture prisoners. This prompted Cameron to call off the Papuans from leading the advance and sent the leading Papuan platoon to reconnoiter the inland trails while the infantry led the advance on the right. The men advanced sluggishly as a result of the mixture of muddy tracks and enemy corpses. They reached Roinji 1 on the 6th then Roinji 2 on the 7th. During the afternoon the Papuans reached Gali 1 where they managed to kill 24 Japanese stragglers and captured 3 prisoners. Each day the Papuans killed on average 10-15 Japanese, but it was not until the 8th when they encountered a real Japanese rearguard at Weber Point. The Papuans performed a frontal assault killing 53 Japanese and captured another 4 prisoners. By the night on February 9, the leading company was 2000 yards west of Malalamai and 3500 yards from the American’s most forward outpost at Yagomai when they fought another larger group of Japanese. 61 Japanese were killed and 9 prisoners taken in the day; and on February 10, the 30th Battalion at last reached Yagomai. Here they finally linked with the American force at Saidor. It was decided that the 5th Division would not operate west of the Yaut, so Brigadier Cameron was instructed to mop up the Tapen and Nokopo areas. Meanwhile, the 35th Battalion advanced towards Bwana, where they killed 31 Japanese.

On the 18th, the Australians killed 40 Japanese at Gabutamon and another 142 in the Tapen area; 3 days later, they attacked Wandiluk, where they killed 57 Japanese. After the 22nd, the pursuit was largely carried on by the Papuans towards Nokopo. During this time until March 1st, the 8th Brigade reported killing 734 Japanese, found 1793 dead and took 48 prisoners. The Australians and Papuan had suffered 3 deaths and 5 wounded. Despite his losses, General Nakano and his men had yet again cheated death. In a letter on 21st March Lt General Frank Berryman wrote: "About 8,000 semi-starved, ill equipped and dispirited Japanese bypassed Saidor. It was disappointing that the fruits of victory were not fully reaped, and that once again the remnants of 51st Division escaped our clutches." Meanwhile General Morshead had been planning to relieve the 7th division with the fresh 11th division Major-General Allan Boase. But General Vasey convinced him instead to let him take over the drive on Madang by the end of January. Now the 58th/59th Battalion relieved the 2/10th in the right-hand sector from 4100 through Crater Hill and Kankirei Saddle to Cam's Hill, with the task of patrolling the area east of Cam's Hill, the headwaters of the Mosa River, and forward along the upper Mindjim River Valley to Paipa 2. The 57th/60th relieved the 2/9th on the left with positions on the 4100 Feature, the Protheros and Shaggy Ridge, and the task of patrolling forward from Canning's Saddle along the high ground west of the Mindjim. The 24th Battalion relieved the 2/12th in reserve. 

Now Brigadier Hammer had the task of patrolling forward from the Kankirei Saddle. As typical for New Guinea, the terrain facing them would be formidable. Hammer had this to say in a report "The country in the Finisterre Ranges is rugged, steep, precipitous and covered with dense rain forest. It rains heavily almost every day thus making living conditions uncomfortable. By day it is hot, by night three blankets are necessary. There is, therefore, a constant battle with mud, slush, rain and cold. To allow freedom of movement over this mud it was necessary to corduroy every track in the area." By late February Hammer dispatched a number of small patrols towards Amuson and Saipa 2. On the right flank Lt Brewster with a patrol from the 58th/59th investigated the valley of the Mosa River as far as Amuson, and returned after 4 days reporting the area was clear. In the central area a patrol from the 57th/60th brushed with an enemy patrol near Saipa 2, with some support from the guns of the 4th Field Regiment. On the 28th a patrol from the 57th/60th, led by Lt Besier, attacked Saipa 2 three times with supporting artillery fire, but all attempts to enter the village were repulsed. On February 26, the 58th/59th Battalion was instructed to establish a company patrol base on Amuson and send out a platoon reconnaissance patrol to the coast in the Mindjim-Melamu area, which managed to establish some observation posts overlooking Astrolabe Bay in early March. Hammer also sent the 57th/60th Battalion to the Paipa area in preparation for an attack on Saipa 2. 

Meanwhile, after the conclusion of Operation Dexterity on February 10th General Krueger handed command to Major-General William Gill over the Saidor area and he began to bring the remaining elements of his 32nd division.  Gill then began plans for a secondary landing at the Yalau Plantation, around 30 miles west of Saidor. He hoped to establish a new forward base there and possibly intercept enemy stragglers trying to bypass the Saidor area.The 2nd battalion, 126th regiment led by Lt Colonel Oliver O. Dixon successfully landed on March 5th. 54 landing crafts unloaded 1348 within 9 waves, seeing little to no opposition. As men patrolled east and west from Yalau, they encountered and killed a few Japanese and found many already dead. They would reach Bau Plantation on March 9th, where they ran into a detachment of General Nakai’s 3rd battalion, 239th regiment. But yet again we must not shift our attention somewhere we have not been in quite some time, the Indian Ocean. 

The Commander in Chief, Southwest Area Fleet, Vice-Admiral Takasu Shiro had decided to dispatch heavy cruisers Aoba, Chikuma, and Tone, under the command of Rear-Admiral Sakonju Naomasa, to raid Allied shipping on the main route between Aden and Fremantle. Departing the Lingga Islands on February 27, the heavy cruisers were escorted by light cruisers Kinu and Ōi and 3 destroyers through the Sunda Strait. The raiders were also supported by 10 medium bombers and 3-4 seaplanes based in Sumatra and west Java which conducted patrols in the direction of Ceylon. 3-4 submarines from the 8th Flotilla also monitored Allied shipping movements near Ceylon, the Maldive Islands and Chagos Archipelago. On March 6th the allies detected the force near the Lombok Strait. Fearing a possible attack, Western Australia was reinforced and the British Eastern Fleet was diverted.

On the morning of March 9th, Sakonju’s cruiser came across the 6200 ton British steamer Behar between Fremantle and Colombo. Upon sighting the Japanese ships, Behar's Captain Maurice Symons, ordered that his radio operator transmit the "RRR" code in order to notify other ships and Allied bases that the merchant ship was being attacked by surface raiders. Tone's signals room picked up the message,. The Tone then began signaling repeatedly to the Behar to surrender, but the Behar continued to flee, prompting the cruiser to open fire. Behar was hit a few times to her prow and stern, killing 3 crewmembers. Within 5 minutes Behar’s crew and passengers began abandoning ship as she sank. 104-108 survivors were rescued by the Tone. Following the attack, Sakonju believed it was too dangerous to continue raiding as Behar had sent out a distress signal. So he turned back, reaching Tanjung Priok on March 15th. 

Shortly after the Behar survivors were rescued, Sakonju sent a radio message to Tone's commanding officer, Captain Mayuzumi Haruo, reprimanding him for taking non-essential personnel prisoner and not capturing the merchant ship. In this message Sakonju ordered that the survivors be killed. Mayuzumi was unwilling to do so, however, as he felt that this would violate his Christian religious beliefs. His executive officer, Commander Mii Junsuke, also opposed killing the prisoners deeming it dishonorable. Mayuzumi radioed a request to Sakonju that the prisoners be put ashore, but this was rejected. The captain then visited Aoba to argue his case, but Sakonju remained unmoved and told Mayuzumi to "obey my orders". Despite his misgivings, Mayuzumi ultimately decided to kill the prisoners. On the night of March 18, all the prisoners on board Tone were beheaded by several of the cruiser's officers. Mayuzumi watched the killings from the ship's bridge but Mii refused to take part. The number of the crew to be executed was between 65 and at least 100. Following the massacre 15-36 survivors were transferred to Aoba. The party sent to Aoba included Symonds, the Behar's chief officer and several of the senior officers as well as both of the ship's female passengers. All of this group were later landed at Tanjung Priok.

After the war, the Allies prosecuted the officers responsible for the murders on board the Tone. Vice Admiral Takasu died from disease in September 1944, but Sakonju was tried by the British in 1947 at Hong Kong and sentenced to death and executed 21 January 1948. Mayuzumi was convicted for his role in the killings and sentenced to 7 years imprisonment. Sakonju stated in his affidavit that he was 'retaliating against the execution and inhuman treatment of Japanese prisoners by the allies in Guadalcanal'. Mayuzumi stated in his defense that he was following Sakonju's orders. Mayuzumi received a light sentence due to his repeated requests for clemency for the prisoner's lives.

Operation Hailstone saw what was once called the Gibraltar of the Pacific, Truk nearly annihilated. She could no longer be counted upon to thwart allied sea and air units in the region. The Australians on New Guinea were not letting up on the retreating Japanese and a terrible and needless massacre took place in the Indian Ocean.

 

- 116 - Pacific War - The Fall of Kwajalein , February 6-13, 1944

Last time we spoke about Operation Flintlock, the invasion of the Marshall islands. The allies brought overwhelming power against the Marshalls, unleashing the simultaneous invasions of numerous islands in an attempt to strike at the heart of the island chain at Kwajalein. The horror of the Gilbert Island campaign plagued the minds of the commanders who hoped to thwart such carnage. Airstrikes, naval bombardments and massive amounts of land based artillery smashed the Japanese defenders into submission before amphibious assaults were made. Countless islands such as Roi-Namur fell one by one as the Americans secured places to deploy further artillery to forces the ultimate submission of the defenses on Kwajalein. The casualties were light, but the fight for Kwajalein would soon descend into a bitter struggle, for the Japanese were not going to give up their stronghold without a good fight.

This episode is The Fall of Kwajalein

Operation Flintlock went off with a bang, and was initially a grand success. Aerial bombing, followed by naval bombardment and then land based artillery was smashing the Japanese defenders into submission. One by one the islands were falling into the Americans hands. On the second day of the battle, Roi-Namur, the northern objective was seized. Yet the stronghold of Kwajalein would provide much more of a fight. Back on the morning of January 28th Admiral Frederick Sherman’s Task Force 58.3 landed a knockout blow against Kwajalein’s airfield. Dawn saw a Hellcat fighter sweep ensure the airfield would not be tossing any further action before the amphibious assault occurred. The next day Sherman’s force hit Eniwetok with the same kind of treatment. Sherman’s carriers would remain off Eniwetok for 3 days while his aircraft smashed its airfields and ground installations. On the third say not much was left, just heaps of rubble and a few scattered palm trees stripped of their foliage. Sherman’s airmen reported “they could not find any targets on the ground or in the lagoon that seemed worth bombing, and the island looked like a desert waste.” The warships came in on the 31st just off Roi and at 6:51am, Admiral Conolly maneuvered Maryland 2000 yards away from the northern beaches before unleashing 16 inch guns. As Holland Smith put it “So close that his guns almost poked their muzzles into Japanese positions.” By 7:15am the naval guns went silent as carrier planes came swooping in. Then 127mm artillery from Roi began firing, alongside cruisers and destroyers. Return fire occurred, but for a very short amount of time as they were snuffed out. Admiral Truman Hedding recalled “We learned a lot about softening up these islands before we sent the Marines in. We really worked that place over. They developed a tactic called the ‘Spruance haircut.’ We just knocked everything down; there wasn’t even a palm tree left.” 

The Kwajalein atoll islands were hit with 15,000 tons of bombs and naval shells in 72hrs. Admiral Turner would make a Churchillian statement about the event “Never in the history of human conflict has so much been thrown by so many at so few.” Then transports carrying nearly 64,000 men of the 4th marine division and the 7th army division were launched at Ivan, Jacob, Allen, Andrew, Albert and Abraham islands. Once they were secured, the marines set up artillery batteries. The 7th infantry division was assigned the task of taking the banana shaped Kwajalein island as their colleagues set up 105mm and 155mm howitzers on nearby Roi-Namur. The 32nd and 184th regiments landed on the lagoon side at 9:30am on February 1st, first encountered only feeble and intermittent resistance. The eastern half of the island was secured in quick time, as the bombardments had certainly inflicted heavy casualties upon the enemy. The army moved slowly and methodically, advancing cautiously against the Japanese fixed positions. Soon they reached Carl Road, where they were met with an impressive defense system consisting of an anti-tank ditch on the south and a long rifle trench on the north.

As February 2nd came on, so did another wide scale smashing of the Japanese. Artillery fire on Carlson Island and from the 32nd Regiments Cannon Company in the Wart Area coordinated with the tank and infantry movements. While the new assault units were moving up, the enemy in Corn Strong Point were kept under heavy artillery bombardment and were isolated from possible reinforcements by naval gunfire. Enemy guns that were still active in the northeastern end of the island were struck by dive bombers. The jump-off was ordered for 12:45. A series of delays deferred this crucial attack over an hour. To assemble the staff and coordinate the plans for employing tanks, artillery, and infantry while the 3d Battalion made its approach march, proved difficult to arrange. The time for the assault had passed before the planning difficulties were resolved. Then came notice of an air strike to be made at 1:15pm later postponed, on Admiral Turner's order, to 1:30, thus necessitating the suspension of all artillery fire. Since the attack on Corn Strong Point was to be immediately preceded by a heavy artillery barrage, the whole operation was postponed to 2:00.

For the initial assault on the tank trap and Corn Strong Point, Colonel Logie’s 32d Infantry's 3d Battalion was ordered to pass through its 2nd Battalion at Carl Road and to lead the attack. These fresh troops were to be supported by the tanks of A and D comapnies, 767th Tank Battalion and, from the left flank, by the tanks of B company, which would be temporarily detached from the 184th. The tanks of A company, 767th Tank Battalion, lined up along Carl Road to fire against the strong point, while those from B company took up positions almost at right angles to that road and prepared to strike the enemy from the left flank during the first stage of the attack. One of the batteries on Carlson continued to fire during the air strike, and the Cannon Company's howitzers also laid a preparation on the target area before the advance commenced at 2pm. Then, while the artillery lifted fire to ground northeast of the target, the tanks and infantry approached the tank trap in a 225-yard advance across open ground. The tanks poured machine gun fire into the area. Thirty yards behind them the troops came forward to the shelter of the tank ditch without receiving an enemy shot. The Japanese were pinned down. The assault initially saw the Americans pin down the Japanese. While the left wing of infantry troops started to push across the wide tank barrier, the tanks on their left momentarily broke off fire from the flank. A few tanks from A company, 767th Tank Battalion, moved toward the ocean to bypass the deep ditch, and the others after a brief hesitation laid a base of fire to cover the infantry's advance. The tanks hesitated to poke out along the flimsy wooden bridge by which Wallace Road cut through the angle of the tank trap. At this stage, a concentration of white phosphorus shells commenced to fall into the area in which I company, 32nd Infantry, was moving, and countless men were burned. After hesitating briefly the infantry moved steadily to the tank ditch. There the troops remained for some time because the medium tanks pulled back claiming they could not get over the ditch.

The tanks finally broke through and began to make their way to the beach smashing pillboxes in the Corn strongpoint. An estimated 100 Japanese were killed in the area, the majority by demolition charges carried forward by engineer details while rifle and BAR men covered them. Little or no defense was put up against these tactics. The Japanese remained huddled in their shelters in spite of efforts made to coax them out to surrender. Only a single prisoner was taken in the whole area. Grenades were thrown into the shelters, and those who survived were then destroyed by demolition charges. Altogether, it took about 35 minutes to reduce Corn Strong Point once the American infantry got beyond the tank trap. Contact between the forward battalion of the 32nd Infantry and that of the 184th was temporarily lost during this fray, and K company, 32nd Infantry, moved through the left platoon of I company to establish contact firmly as soon as Corn Strong Point was taken. Advance to the Nora Road line seemed practicable within the time remaining before taking defensive positions for the night. To escape spending the night in an area too heavily wooded for security, the 3rd Battalion, 32nd Infantry, planned to advance northeast of the junction of Nora Road and Wallace Road, even though that would place its perimeter slightly forward of the 184th's front-line elements, which were resting just short of Nora Road itself.

To the north, Colonel O’Sullivan’s 2nd Battalion began advancing at 12:45 without tank support. F Company was on the right while E Company on the left along the lagoon. For the first 45 minutes no serious resistance was met. There were no tank obstacles in the area and the enemy's positions along the lagoon shore were less formidable than had been expected. At 1:30, however, the 184th had to lend its medium tanks to the 32nd Infantry as the latter moved against Corn Strong Point. This left the infantry unprotected at a time when they began to meet their first serious resistance. Without the tank support the infantry became stalled. The 184th suffered over 60 casualties by the end of the day, including the loss of F Company’s commanding officer. O’Sullivan was forced to organize night defenses just 100 yards northeast of Carl Road, which also forced Logie to pull back to the abandoned trenches of Corn for the night. Heavy casualties were suffered that day, with 11 dead and 241 wounded. Japanese prisoners reported only 200 to 300 defenders remained, so the Americans expected a banzai charge to occur during the night. General Corlett's headquarters warned, "Be alert for counterattack at anytime day or night, it's bound to come. The Jap makes his suicide counterattack at dawn on the day after his cause becomes hopeless. Watch out tomorrow morning.”

Yet there was no attach, so General Corlett prepared his men for a new assault at 07:15am. For the next day's operations, General Corlett ordered the two assault regiments: "Organize vigorous attack 0715 tomorrow… Finish the job not later than 1500 3 February. The Northern Force [at Roi-Namur] has finished the job…".

At this point the Americans on Kwajalein faced a narrow 2000 yards of island. After artillery rained down at 7am, O’Sullivans 1st battalion advanced. In the first 150 yard B Company, along the lagoon, and Company A, at the right, advanced through rubble and broken trees west of Nora Road without more than scattered rifle fire from Japanese riflemen and occasional light machine gun fire from pillboxes. Their momentum carried them on for another 75 yards with such rapidity that the prospects for swift advance seemed excellent. B Company cleaned out an air raid shelter with grenades and shot down fleeing Japanese wearing arm bands like those of the American troops. Both companies were advancing over ground that had been under American mortar fire just before the jumpoff. At 8:06 enemy opposition was reported to be weak. After 250 yards the Americans reached the Admiralty area, finding a group of shattered buildings along the lagoon shore where it was believed the Japanese HQ was. Among the ruins were several underground shelters, with great earthen mounds above them. There were also concrete blockhouses. 

Against strong resistance, B Company would not be able to advance further; A Company, meanwhile, pushed farther north and attempted to attack from the flank through the Admiralty area, but became quickly bogged down. At the same time, Logie sent forward his 3rd Battalion, with I Company rapidly advancing along the coast while K Company stopped to subdue a large concrete pillbox on the corner of the Admiralty area. By midday, I Company reached Noel Road and K Company successfully bypassed the Admiralty area. Yet behind them, there was a vertical gap including most of the Admiralty area between the two regiments. Thus, Corlett sent Logie’s 1st Battalion to cover the gap and O’Sullivan’s 2nd Battalion to swing right and continue the advance north while his 1st Battalion contained and neutralized the Admiralty area. At 3:30, the new attack was launched, with Logie’s 3rd Battalion rapidly smashing into the Nap strongpoint while O’Sullivan’s 1st Battalion concentrated on the Admiralty area and his 2nd Battalion attacked north towards Nob Pier.

E Company started its attack before those of either G Company or the 1st Battalion. At 2:40 E Company began moving northwest. Somewhat more than half an hour later E Company  crossed Noel Road, with G Company on their right. 2 medium and 2 light tanks, taken over from the 1st Battalion, moved forward with each of the companies, and each had one squad of engineer troops with demolitions. Enemy rifle fire was heavy. The men broke up into small groups, proceeding unevenly in the general direction of Nob Pier. Between 6:30 and 7:00, Captain Peter Blaettler, commander of E Company was seriously wounded. Control from the battalion command post was lost seeing the men hugging the ground to avoid sharp fire from enemy riflemen. Colonel Aulich became separated from the main part of his battalion and was to remain so until the next morning, for all intensive purposes he lost command of his unit. The 2nd Battalion's attack was pushed along the eastern side of Will Road toward Nathan Road, but as sunset approached it became evident not only that Company E would not reach Nob Pier but also that across Will Road on the left flank there was an area with many strong enemy defense positions too powerful to be occupied in the 45 minutes before dark.

Meanwhile, at 3:45 A Company 1st battalion was joined by 2 medium tanks and C Company  by 2 mediums and 2 M10 tank destroyers. At 4:05 they assaulted the western edge of the built-up Admiralty area along a 300 yard front, with A Company’s right wing somewhat south of Noel Road. 10 minutes later they advanced towards the lagoon. Will Road was crossed shortly after 4:30. The enemy was much more firmly established between the highway and the beach, in pillboxes, blockhouses, and strong shelters. Mortar fire kept the enemy down until the tanks and infantry approached. The coordinated effort of tanks, infantry, and demolition teams ran very smoothly, gradually destroying the pillboxes and blockhouses of the Admiralty area, successfully reaching the lagoon by 6pm. 

To the east, Logie’s I Company rapidly reduced the weakly-defended Nap strongpoint and then pushed forward to the objective Nathan Road with haste while the other companies made slower progress against stronger defenses and would not be able to reach their objectives before nightfall. The Japanese in the areas south of the front line, were in greater numbers than on either of the preceding nights of the Kwajalein Island operation. They prowled in the forward area all night. Some incidents occurred as far to the rear as Corn Strong Point, more than a 1000 yards from the 32nd Infantry's advanced position. Japanese came out of shelters, screaming and yelling, throwing grenades, and charging at the men in their foxholes. They fired rifles and threw grenades from buildings that offered places of advantage. In a pocket northeast of the Admiralty area, they greatly harassed the companies near them. Attacks from the north and from the lagoon shore were also attempted by enemy troops at various times during the night. Just after sunset, a bugle could be heard sounding among the enemy shelters near the base of Nob Pier, and shortly afterward a headlong counterattack by screaming Japanese was made toward E and G Companies, 184th Regiment. As the Japanese tried to cross Will Road, they were cut down to the last man. 5 more attacks were broken up before they were actually in progress by barrages along the entire front from mortars and from the supporting batteries of artillery on Carlson Island; and more attacks followed after midnight. From various positions beyond Nathan Road, enemy machine gun, mortar, and artillery fire was directed into the forward area at irregular intervals during the night, sometimes coinciding so closely with the fire from Carlson Island that Japanese monitoring of the artillery radio was suspected. Nonetheless, over 1000 yards had been gained, by February 3. The Americans estimated they had killed around 1300 Japanese, more than were expected to still be in the island, at the cost of 54 dead and 255 wounded. 

After sunset, several Japanese counterattacks and infiltration attempts were carried out against the steadfast Americans, all ending disastrously. Corlett expected to end the enemy resistance by February 4; but far too many small pockets remained in the rear and the reserve battalions were experiencing difficulties rooting them out. Corlett’s final plan was for Logie’s 1st Battalion to clear the remainder of the island, allowing  Companies C, B and A to attack through O’Sullivan’s 2nd Battalion and Logie’s 3rd Battalion. Unbeknownst to him, O’Sullivan also directed his 2nd Battalion to attack towards Nob Pier in order to complete the unfinished task of the previous day. 

At 7:15, Corlett unleashed his final attack, supported by tanks. On the east, Logie’s Companies A and B ran into a full-scale battle with the Japanese who had been bypassed the day before and who now poured heavy fire on the companies as they advanced toward the line of departure. It was not until 10:00 that the 2 1st Battalion companies reached the lines held by the 3rd Battalion. Then, the Americans successfully managed to advance 200 yards past Nathan Road, where the advance was stopped pending relief. Meanwhile, to the west, the attack of O’Sullivan’s 2nd Battalion, supported by B Company , prevented the advance of Logie’s C Company until 11:00. The Americans managed to push towards Nob Pier by 1:00, where they found no enemy resistance. Behind them, the lagoon shore continued to be mopped up, showcasing a surprising number of Japanese and Koreans surrendering. 

All forward movement of the 1st Battalion had stopped, its line consisting of a series of small, exhausted groups in a dense confusion of debris. The ground was interlaced with innumerable trenches and foul with bodies of the enemy, many of them long dead. Some of the corpses had been mangled by maneuvering tanks, adding greatly to the nauseating stench that blighted the area. Finally, at 3:45, Logie’s 2nd Battalion passed through the 1st to complete the assault along Kwajalein. These troops would successfully push to the island’s northern tip, blasting through the remaining Japanese camouflaged dugouts and ruined concrete blockhouses. 

As in every other island battle, Japanese stragglers had infiltrated the American lines through tunnels and overlooked bunkers, and the assault troops quickly learned to watch their backs. Nisei interpreters broadcast surrender appeals through loudspeakers, but there were only a few dozen takers, and most of the men who gave themselves up were Korean laborers. At long last, G Company reached Nero Point at 3:15. At 4:10 Corlett radioed to Admiral Turner: "All organized resistance… has ceased. The troops have been organized for mopping up operations." yet F Company, would still have to methodically destroy the enemy positions until they finally secured Kwajalein’s northern end at 7:20. Ken Dodson went ashore the next morning. Writing to his wife, he described a desolate landscape of “shell craters and hillocks of upturned coral. Some of the Japanese had been dead from the first bombardment, the day before we landed. Their bodies were seared and bloated, and the stench was sickening. I saw one half buried in a pillbox. You could not tell whether he had on any clothes or not. The skin was burned off his back and his head lay a few feet from his body. Another looked like a bronze statue in Golden Gate Park. He lay forward in a crouch, helmet still on, both hands holding on to a coconut log of his pillbox. There were many, many others. I lie in bed at night remembering how they looked, and that awful sweetish sickening stench of powder, and kerosene and decaying human flesh, and I wonder, after all, what war is all about. I feel sorry for those Japs in a way. They died courageously after a stubborn, last-ditch, hopeless fight. They fought for the things they had been taught to believe in, with their poor little bundles with pictures of their wives and kiddies tied to their belts. . . . They can’t tell me war is a fine and noble thing.’ Losses during the last day were 252 wounded, with 65 Japanese killed and over 100 captured. Thus, for the Battle of Kwajalein Island, the Americans suffered a total of 142 killed, 845 wounded and 2 missing, killing around 4300 Japanese and capturing another 166.

During the week after Operation Flintlock, numerous high ranking visitors descended on the battle-scarred islands of Kwajalein Atoll. Admiral Nimitz flew out from Pearl Harbor with an entourage of officers. On February 5, when fires were still burning on Kwajalein Island, he toured the blackened wastes alongside Spruance, Turner, Smith, and several other major commanders of the fleet and Amphibious Corps. Three weeks earlier Nimitz had been the guest of honor at a huge “Texas Picnic” in a Honolulu park. Walking among 40,000 sailors, soldiers, and civilians. He had pitched horseshoes, posed for photographs, and signed autographs. Afterward, the park looked as if it had been hit by a hurricane—clean-up crews had to cart away more than 50 truckloads of garbage and debris. An estimated 120,000 beer bottles had been left strewn across the grass. Now, upon setting foot on the lagoon beach at Kwajalein, Nimitz was waylaid by a mob of correspondents. “What do you think of the island?” one asked. The admiral drew a cheerful laugh by replying, “Gentlemen, it’s the worst scene of devastation I have ever witnessed—except for the Texas picnic.”

The operation had been a model one in almost every respect. The attacking force had achieved strategic surprise; artillery preparation, naval gunfire, and aerial bombardment had successfully softened up the target in a fashion unexcelled at any other time in the Pacific War; the ship-to-shore movement had been conducted expeditiously and without too many hiccups; supplies flowed ashore and to the front lines relatively smoothly and without interruption; the infantry-engineer teams assisted by tanks moved steadily clearing the enemy from shelters and pillboxes; and American casualties had been fairly light. Altogether, the battle for Kwajalein represented the ideal for all military operations.

To complete the conquest of the southern Kwajalein islands, detachments of amphibian tanks had been landed on Buster and Byron back on February 3. Troops of the 2nd Battalion, 17th Regiment landed on Burnet and Blakenship on February 4; the chain between Ashberry and Bennett was secured by February 5. On that same day, Clement, Clarence, and Clifford Islands were also secured, although on Clifton a force of 101 Japanese fought to the death. Beverly, Benson and Berlin were also secured on February 5, seeing 119 Japanese dead on the latter. Bennett fell against the 7th Reconnaissance Troop and O’Sullivan’s 3rd Battalion with 94 Japanese killed. Most importantly, Colonel Zimmerman’s 1st and 3rd Battalions landed on Burton’s Beach Orange 4. The fortifications on Burton were much lighter than those on Kwajalein, mostly machine gun positions and rifle pits. These were organized at the beaches with a concentration of dual-purpose machine guns grouped around the seaplane base in the lagoon. At the base of the south seaplane ramp was a 20-mm. antiaircraft machine gun. Near it, and between the two seaplane ramps, were two 13-mm. single-mount machine guns, three 7.7-mm. machine guns, and a concrete pillbox. Two 8-cm. dual-purpose guns were located on the ocean shore. The large number of empty machine gun emplacements would seem to indicate that the defenses of the island had not been completed at the time of the invasion. The few pillboxes found in the vicinity of the seaplane base were small, reinforced concrete shelters, each with two firing ports facing seaward. Most of the fire trenches and rifle pits were on the ocean side at the center of the island and at the north and south ends of the island. On the morning of February 3 after a heavy artillery, air and naval bombardment, the 1st Battalion traversed the southern end of the island against weak resistance and began pushing north supported by tanks, ultimately getting stopped by strong enemy resistance at Bailey Pier. 

The following morning, the assault was resumed at 0730, the main enemy resistance had shifted to the eastern side of the island. The Japanese had reoccupied four pillboxes close to the American front line on the ocean side, and were able to hold up A Company, but with the aid of self-propelled mounts, the company took the positions. During the morning, a flight of five Navy bombers made two runs over targets that had been spotted with the aid of information from a prisoner. The planes dropped a total of two and three quarters tons on an ammunition dump, a shelter, and a heavy machine gun that had an excellent field of fire across the hangar apron. Direct hits on these targets apparently disheartened the enemy. Not a single shot was fired by them at any later time during the operation. They remained buried in their dugouts until forced out or until they killed themselves. By 1130, when the 3d Battalion passed through and took up the assault, B Company  had moved about 350 yards to the southern edge of the concrete apron, and on the right A Company  was fifty to 75 yards farther back.

The 3rd Battalion continued the advance north against meager resistance, ultimately reaching Burton’s northern tip by 12:10. After this, the last of the enemy were readily mopped up; and by 3:37, the island was fully secured. During this battle, the 17th Regiment suffered 7 killed and 82 wounded while reporting 450 Japanese dead. Meanwhile, to the north, the 25th Marines led by Colonel Samuel C. Cumming occupied some 55 islands in the northern part of the atoll between February 2-7, finding absolutely no enemy resistance. With Kwajalein Atoll finally secured, the next objective in the Marshalls for Admirals Nimitz and Spruance would be Eniwetok, where Major-General Nishida Yoshimi was preparing his men to fight to the last. Yet that’s it for the Marshall islands today, as now we are traveling over to the CBI theater, where Generals Christison and Stilwell’s offensives continued. 

Now last time we left off with the gang in Burma General Liao’s 22nd division, Colonel Rothwell Brown’s 1st provisional tank group, General Merrill’s Galahad Unit alongside Chinese and American engineers were busy building the Ledo Road through the Hukawng valley. Location parties up ahead cleared a trace the width of a bulldozer and put in the center-line stakes. The final clearing averaged 150 feet. The route of the Ledo Road in some cases followed existing roads, a circumstance that did not greatly diminish the amount of clearing needed. Most clearing was by bulldozer. Combat trails and access roads were cleared to the necessary minimum that would permit heavy equipment to use them. In the valleys, the road was generally built on embankments in order to lift it above flood level. In mountainous regions, side-hill cuts were used. The road itself had about seven culverts to the mile in the mountains and five to the mile in the lowlands. These culverts were most necessary as the road was a barrier to the normal runoff of water. Surfacing was with stream-bed gravel in the valley sections and, so far as hauling permitted, natural gravel in the mountainous sections. Surfacing was about ten inches thick on the average, and from twenty to twenty-eight feet wide. Compaction was by the normal road traffic. Two regiments of Chinese engineers did pioneer construction work. There was also a combat road, a hasty improvement of the existing Kamaing Road plus the Kachin and Naga trails, that ran through Shingbwiyang, Yupbang Ga, and Taihpa Ga, then went south. The trace of the Ledo Road was moved to higher ground on the north. Forward construction units were rationed from combat supply points.

Meanwhile Vinegar Joe sought to end the campaign with a single decisive victory. He planned to deploy the 1st Tank Battalion as an armored spearhead against Maingkwan, the 1st battalion, 66th regiment, the 113th was to follow down the road to take over successive positions, while the 114th would assemble at Taihpa in reserve and the 112th was to protect the flank east of the Tanai, advancing on Mashi Daru. He expected his men to hit the enemy across their rear areas. Now January had been a very rainy month, armored warfare does not do well in mud, so it was important the terrain was dry for the offensive. Stilwell would end up on February 4th decided to shift the bulk of the 22nd division to seize Yawngbang-Lakyen line while General Sun’s 38th Division cleaned up the area south and east of the Tanai. 

Once this first phase was done, then General Liao’s 2 regiments could support an armored advance south towards Walawbum. The bad weather, however, had also delayed road work and hampered their supply lines. Stilwell biding his time, building up a reserve at Shingbwiyang and Ningam, while the men progressed their work on the Ledo Road, and built an airfield at Taihpa before launching his second phase. This unfortunately also gave enough time for General Tanaka to prepare an orderly withdrawal towards Maingkwan. During early february, General Sun’s 32nd division successfully accomplished their part of the mission, but to the southwest, the enveloping hook from the Taro Plain did not go as planned. By February 14th, the 66th regiment were beginning to arrive on the Taro Plain through heavy rain, but only the 3rd battalion of the 65th regiment managed to join them. The 66th regiment was forced to continue without the proper support until they diverted to Yawngbang Ga which they seized on the 16th. By the 18th, Stilwell and Liao personally went over to check on their regiment’s location and found the entire force was within the neighborhood of the 66th command post. It seems the utter confusion during these movements saved the Japanese, as quoted by General Tanaka: "If the Chinese 65th and 66th Infantry Regiments operating in the vicinity of Yawngbang had been prompt in closing in on our left rear flank on the 15th or 16th, as predicted, the main force of the 18th Division would have faced a grave crisis." After sorting out the confusion,  the Chinese advanced from Yawngbang Ga to Lakyen Ga. There they captured a Japanese document indicating they were withdrawing. Thus another chance to envelop the enemy had thus been lost. 

 

Meanwhile, to support Stilwell’s offensive, the two Allied long-range penetration units, the Chindits and Merrill’s Marauders, were preparing to embark on a new mission, codenamed Operation Thursday. It was to be the second Chindit expedition with the objective of mounting a long range penetration behind the Japanese who were opposing Stilwells forces in the Northern front. It was hoping the action would prevent the arrival of any reinforcements from the two Japanese divisions on the Central Front. General Hap Arnold wanted his airmen to take the Chindits behind Japanese lines, carry their supplies, evacuate their wounded and eventually fly them off, so he decided to create the 1st Air Commando Unit, under Lieutenant-Colonel Philip Cochram. The unit consisted of a squadron of P-51s; one of B-25s; 100 C4A Waco gliders; and a squadron of C-47s. Arnold spelled out the mission to Cochram and Lieutenant-Colonel John Alison, his deputy. "This man [Wingate] has really done some remarkable things. He has walked through the jungles. He has carried his supplies on mules. It takes him about six weeks to get his men through the jungle, across the rivers, and in behind the Japanese lines. The next time he goes in, I don't want him to walk. I want him to go by air. I want to make this an air operation completely independent of land transport. I want to demonstrate that you can use the air just like the navy uses the sea. You can land and maintain a force and support it in battle. I want you to go in there and take out General Wingate's wounded. We will make available the resources that you need. 'I not only want you to do that... but I want the USAAF to spearhead General Wingate's operations.' We gathered he wouldn't mind if we turned it into an air show."

The mad onion lad Wingate also wanted to created strongholds within the Japanese controlled areas that could serve as bases to receive aircrafts of all types, store  supplies, hold wounded until they could be extracted, and act as centers for locals resisting the enemy. The motto for the Stronghold, as he called it, was “No Surrender”. Meanwhile Stilwell ordered Merril to close in on Ledo by February 7th, and the last American unit would arrive to Margherita on February 9th. Merrill’s Marauders were to assemble at Ningbyen by February 21st whereupon they would envelop the 18th divisions east flank and block the Kamaing road near Shaduzap with the support of Sun’s 113th Regiment. Simultaneously Stilwell’s other troops were preparing for their attack on Maingkwan.

Further in the south General Christison’s 15th Corps was in a lot of trouble. The Japanese had been bringing in a lot of reinforcements for their forthcoming Arakan counteroffensive from both within and outside the Burma theater throughout December and January. By early February, General Hanaya had assembled his men and was ready to launch the first phase of Operation Ha-Go. General Hanaya planned to destroy the 7th Indian Division in the region east of Mayu Range using a pincer movement launched simultaneously from the north and south. After that, he would shift the main weight of his 55th Division near Ngangyaung against the 5th Indian Division in the Maungdaw region west of the Mayu Range. From there, he hoped to advance along the Kaladan valley to perform the phase of Ha-Go, named the Kaladan Operation. For this the men would advance towards Chittagong to distract attention from around Imphal and to draw the British reserves into Arakan. 

On the night of February 3, Hanaya unleashed his offensive, with several columns, under the command of Major-General Sakurai Tokutaro, commander of the 55th Infantry Group. His force secretly infiltrated through the jungle under the cover of darkness, on the left bank of the Kalapanzin river near Buthidaung, through gaps between the 7th Division’s widely separated brigades. The element of terrain and weather was paramount. Throughout the dry season a morning mist with heavy dew formed daily in the small hours and, unless cleared by rain and wind, normally persisted till well after sunrise; the noise made by the dew falling from the trees on to the dry undergrowth was loud enough to drown the sound of footsteps so that, in the jungle, movement in the early morning could be unheard as well as unseen. The tides were an important factor in planning, for at high tide many of the chaungs were unfordable. The knife-edge ridges into which the Japanese so often dug their defenses presented an unusual artillery problem. If guns were to bring effective fire to bear, they had to be sited on the line of the axis of a ridge, which was always difficult and sometimes impossible. Fire from any other angle meant that reverse slope defenses were untouched and accurate ranging was extremely difficult. The dense jungle covering the hilltops greatly restricted their use as observation points.

Using the early morning mists, Hanaya’s men shrouded their columns advance cutting deeply into the British defenses. At about 9 am the Gwalior Lancers reported to 7th Division by wireless that a column of Japanese about a hundred strong followed by another about eight hundred strong were approaching Taung Bazar. Major-General Frank Messervy immediately ordered his reserve brigade, the 89th to advance north to locate and destroy them and asked 15th Corps to speed up the arrival of the tanks. Christison ordered the 25th Dragoons to send a squadron to Sinzweya and 5th Division to send an infantry detachment to prevent infiltration over Goppe Pass. The 89th Brigade advanced north in two columns: the right column encountered the Japanese at about 4 pm near Ingyaung resulting in hand to hand fighting, and the left reached the bend of the Prein Chaung east of Preingyaung. The right column  dug in at Ingyaung and Lin babi and the left over the Prein Chaung.

Although the main force of the 1st Echelon was delayed by some confusion, the advance guard surprised the Taung Bazar garrison at 7am. Without delay, the Battalion crossed the Kalapanzin River south of Taung Bazar, using captured boats, and was followed closely by the 2nd Echelon and the 3rd Battalion of the 112th Infantry Regiment. The main body of the 1st Echelon crossed the river northwest of Taung Bazar on the morning of the 5th. By 9am Taung Bazar was overwhelmed as the Japanese forces crossed the Kalapanzin River to cut the Ngakyedauk Pass in order to isolate the 7th Division. Meanwhile the 1st Battalion, 213th Regiment headed towards Ngangyaung. The battalion advanced parallel to the Sakurai Column before moving towards Goppe Bazaar. It was held up short of its objective, however, by the leading elements of 26th Indian Division committed from army reserve on 5th February to bolster 15th Corps. Despite this local setback, the Japanese hauled their mountain guns and equipment over the Mayu Range, midway between Goppe and Ngakyedauk, before attacking administrative troops, bridges, dumps, ambushing convoys and building a roadblock on the main line of communications along the Bawli-Maungdaw road. It failed to prevent supplies reaching 5th Indian Division, however, whose ammunition, equipment and food was transported by sea to Maungdaw. Overnight the rear areas of 15th Corps were transformed into the front line with administrative troops bearing much of the burden of dealing with advancing Japanese troops. To the surprise of many officers, they displayed a determination and fighting spirit unknown a year before and took a heavy toll of the Japanese attackers bearing out Slim's direction that every man in the army should be a soldier first and a tradesman or specialist second.

The bulk of the 112th regiment led by Colonel Tanahashi Shinsaku marched towards the pass as the 2nd battalion 143rd regiment and Sakurai’s HQ advanced south. The quickly found enemy resistance near Ingyaung which delayed their advance for over 2 days. Failing to make contact with General Sakurai, the Battalion continued its advance southward, bypassing Awlanbyin. Major Gen. Sakurai and his headquarters also got involved in fighting off enemy counterattacks near Ingyaung on the 5th and 6th and due to failure of his communications, was unable to keep in touch with his units. To further support the offensive, Japanese fighters and bombers from the 5th Air Division’s 7th Air Brigade launched a heavy offensive to gian air superiority over the battlefield, using 34 fighters and 10 bombers. Between the 4th and 14th their fighters flew 350 sorties, and bombers attacked the Bawli and Briasco bridges and Sinzweya. Spitfires intercepted them but had less success than before. Japanese losses were believed to be some 14 aircraft destroyed and a number damaged, while RAF losses during the same period were around 11 fighters.

On february 5th, having made such quick progress, Hanaya ordered the 143rd regiment to advance north. The 3rd battalion, 143rd managed to infiltrate through the Indian brigades en route and joined Sakurai’s men to hit the pass. Seeing the danger, General Slim decided to reinforce Christison with the 26th Indian division led by Under General Lomax. Christison in turn ordered Lomax to move it forward to Bawli Bazar as quickly as possible. Upon their arrival at Bawli North, the 71st Brigade was then ordered to relieve the detachment from 5th Division on Goppe Pass and then attack the Japanese operating in rear of 7th Division. Likewise the 36th Indian division of Major-General F. W. Festing sped up their advance towards Chittagong while C-46 Commandos and C-47 Dakotas air dropped ammunition, food and other supplies to the front units.

On the morning of the 6th, the 112th Regiment reached the sector north of Sinzweya and overran the headquarters of the British-Indian 7th Division while the 1st Battalion cut the Ngakyedauk Pass. In a perfect position to envelop the enemy in Sinzweya, Colonel Tanahashi disregarded the vital necessity for speed and delayed for 24 hours, giving the British time to establish a perimeter defense in the Sinzweya Basin. East of the range at about 5:00am, an enemy force, estimated at battalion strength, penetrated the widely separated posts held by the company of 24th Engineer Battalion defending 7th Division Headquarters, established machine-gun posts on tracks throughout the headquarters area and broke into the signal center. In hand-to-hand fighting the attackers were driven out, but not before all communications had been cut and ciphers compromised. Tanks from Sinzweya moved to the sound of the fighting as soon as it was light but the ground prevented them from reaching the headquarters area; rain which set in about 8:30 further hampered them and they had to withdraw. At about 10:00am, the signal center was finally overrun. Messervy, unable to exercise command any longer, sent orders to all branches of his headquarters to destroy papers and equipment of value and make their way in small parties to Sinzweya. Most of them succeeded in doing so during the following 24 hours.

Major-General Frank Messervy and his staff would manage to successfully escape towards Sinzweya. Consequently, instead of ordering a general withdrawal like the Japanese expected, Christison directed the 9th Brigade to organize a defense of Sinzweya, which was the weakest link of the four isolated, self-contained all-round defensive boxes held by each brigade of the 7th Division. By the 7th, the defense of Sinzweya, also known as the Admin Box had been consolidated. The perimeter consisted of a series of small defended posts held, in the main, by administrative units, except at the south east and southwest corners where the roads entered the area. These were held by 4/8th Gurkhas and a company of 2nd West Yorkshire. There were insufficient troops to hold the whole of the Point 315 feature, and thus there was a deep reentrant between the southeast and northeast corners of the perimeter extending back to the southern end of Ammunition Hill. Most of the artillery was disposed on the southern face with attachments holding perimeter posts. The 25th Dragoons were in mobile reserve in two harbors held by a company of 3/4th Bombay Grenadiers, one each side of Ammunition Hill. The 2nd West Yorkshire constituted the infantry reserve and was located with divisional and garrison headquarters on the western side of Ammunition Hill. The main dressing station in the southwest corner was being moved to a more secure area.

During the night, the Japanese launched an assault against Sinzweya, yet the tenacious defenders managed to hold on against the fierce enemy pressure. That night, the 33rd Brigade also managed to repulse an attack against Sinohbyin, though the arrival of these reinforcements would allow Sakurai to extricate himself from Ingyaung and head to Sinzweya to take command over the assault. On February 8, all British troops east of the Mayu range were receiving supplies by air, yet the strong presence of enemy fighters disrupted the first few attempts. Eventually, British air superiority would be restored. The No. 31 Squadron and 62 Squadron were reinforced on the 10th by 194 Squadron and on the 25th by 117 Squadron, recently arrived from the Middle East. Not only were 7th and 81st Divisions kept supplied with food and ammunition, but such amenities as cigarettes, rum, mail, razor blades and newspapers were delivered by air to the troops in increasing quantities as time went on, certainly a morale booster. Throughout the battle the Strategic Air Force and 224 Group gave constant close support to 15th Corps. In addition to providing escorts for transport squadrons, Hurricanes harried road, river and coastal transport on the Japanese lines of communication to Arakan that movement by day into the area virtually ceased. Tactical bombing of enemy positions was undertaken by two Vengeance squadrons which flew no less than 269 sorties in just over a week.

The transports flew a total of 714 sorties in 5 weeks, successfully delivering nearly 2300 tons of supplies. From the night of February 8 onwards, the Admin and other boxes would also hold firm against repeated ferocious Japanese infantry night assaults, occasional air attacks and limited artillery bombardment from a handful of mountain and battalion guns by day and a medium gun firing from the nearby tunnels, thus showcasing the new spirit of the British-Indian troops. As quoted by Lieutenant-General Pownall: “We’ve learned how to fight where we stand and NOT to be frightened of the bogey of infiltration.”

Kwajalein has finally fallen, leaving the rest of the Marshalls at the mercy of the colossal allied air, land and sea forces. Within Burma, the Chinese, British, Indian and Americans were ferociously meeting the Japanese, showcasing their dominance in the theater was no longer as sure thing, now the Japanese faced a much stronger enemy. 

 

- 115 - Pacific War - Invasion of Marshalls , January 30 - February 6, 1944

Last time we spoke about the fall of Shaggy Ridge, some hardcore patrolling on New Britain and major planning for the invasion of the Marshalls. The Australians seized the Kankeiri saddle, the Prothero’s, Crater Hill and countless other features until finally at last the Japanese had been dislodged from the area. Meanwhile over on New Britain, the Americans were expanding their perimeter and unleashing wave after wave of patrols, trying to figure out where the Japanese were concentrating. It was tireless work, without any good maps in a horribly difficult climate with menacing terrain. The commanders of the central, south and southwest pacific all met to finalize big plans, that would now involved the invasion of the Marshall islands. It seems Dougey boy MacArthur was delivered some setbacks for his grand advance to the Philippines, as the Central Pacific was stealing the drivers seat. 

This episode is Operation Flintlock: The Invasion of the Marshalls

In spite of General Douglas MacArthur’s attempted hijacking of the strategic control over the Pacific campaign, by trying to have the US Navy’s Central Pacific campaign pretty much aborted, it did not pan out. MacArthur had made multiple arguments against their Central plans, stating Nimitz choice of route was “time consuming and expensive in our naval power and shipping” which was really a self-serving argument flying in the face of actual evidence. MacArthur pointed out all the problems faced during the invasion of Tarawa, such as the high casualty rates. The Marines had jumped 2500 miles from New Zealand to hit Tarawa at the cost of 4 days of fighting. Yet Australian soldiers and American GI’s would take nearly a year and a half, through nearly continuously fighting to make the 300 mile journey from Port Moresby to Madang. Operation Cartwheel proved to be extremely laborious, time consuming and costly in terms of materials and men. But from MacArthur's point of view the lives lost were largely Australian and perhaps as some Historians might point out “were politically expendable to a person like MacArthur”. Kind of a hit point to make, that one came from Francis Pike’s Hirohito’s War, go after him not me folks. It was also self evident the supply lines of ships from the west coast of the US to Nimitz Pacific fleet and their Marines, some 5000 or so miles from San Diego to Kwajalein atoll, was shorter than the long route going from the US west coast to Australia then to New Guinea, a colossal 9108 mile trip. By mid 1943 the supply line to MacArthur was nearly double that of Nimitz in distance with increased dangers of IJN submarines prowling about, though as I have said numerous times, the IJN only really figured out the capability of merchant hitting in the late years of the war.  Well in spite of all of that MacArthur gave Brigadier-General Frederick Osborn and MacArthurs trusty lackey Sutherland going to Washington to fight on his behalf against the Joint Chiefs of Staff, they elected to commit themselves to the Central Pacific thrust. It had been a strategic decision based on logistical and strategy…well logic? The 1943 Cairo conference ended just as Tarawa was captured, thus driving the nail in the coffin so to say.

The next target on the way to the Marianas was thus the Marshall islands, way back in the old days they were property of the German empire, that Japan had stolen with ease. Ever since 1938, the Japanese banned any non Japanese ships from the region, thus US intelligence was pretty lax on them. MAGIC intercepts began to give clues as to how the Japanese deployed their troops on the Marshall islands however. This led the allied war planners to leave some “to wither on the vine” like Wotje. It was decided the main target would be Kwajalein. The 380 mile lagoon made it one of the largest in the world, quite beautiful also. Some like Rear Admiral Turner, questioned the risks of going straight into the heart of the Marshall islands, calling the move “too aggressive and dangerous and reckless!” But Nimitz and Spruance were adamant, well this was before Tarawa. The bitter lessons learnt on Tarawa prompted Spruance to determine that “Kwajalein would be struck with violent, overwhelming force and swiftly applied”.

For the invasion of the Marshalls, codenamed Operation Flintlock, the first phase was to be the capture of Kwajalein, earmarked by General Corlett’s 7th division against the southern group of islands in the atoll that included Kawjalein. General Schmidt’s 4th marine division would capture Roi-Namur and the northern islands in the atoll. Furthermore prior to these attacks, Colonel Sheldon’s Sundance Landing Force would hit Majuro Atoll.

Because of the experiences gained during the invasion of the Gilberts, a far greater quantity and variety of amphibious equipment had been made available to the Central Pacific forces. Now the attack force commanders would not have to rely on the faulty communications systems of battleships to maintain proper radio liaison between ship and shore and ship and air. Two newly constructed headquarters ships, each equipped with the latest developments in radio and radar gear and unburdened by gunfire support duties, were provided for the operation. Several improvements were also made in the techniques of softening up the enemy defenses before the first troops touched shore. The US Navy changed their bombardment tactics based on the experience at Tarawa and now used armor piercing shells and fired from closer ranges. These all added would increase the quantity and accuracy of firepower to be delivered before the invasion. To provide a last-minute saturation of the beaches, two new, or rather modified, forms of older types of amphibious equipment were also introduced. The first of these was the amphibian tank LVT-A, which was just the standard amphibian tractor equipped with extra armor plating and mounting a 37-mm gun housed in a turret. The second was the LCI gunboat, an LCI converted into a gunboat by the addition of three 40-mm guns and banks of 4.5-inch rocket launchers. 

Admiral Turner’s plan called for extensive pre-landing bombardment both from surface ships and from aircraft. Most of the Marshall’s airfields had been successfully neutralized by Admiral Hoover’s aircraft over the prior months. To complete preliminary operations, Admiral Mitschers Fast Carrier force launched a heavy strike on January 29 and 30th. On the 30th, eight of Mitschers battleships, accompanied by about a dozen destroyers, were to deliver a dawn bombardment against Kwajalein Island and Roi-Namur. The object was to destroy aircraft, coast defense guns, and personnel, and to render the airfields temporarily useless. At the same time, two advance units of cruisers and destroyers from Turner's task force were to bombard the airfields at Wotje and Maloelap. These dawn bombardments were to be followed by air strikes against each of the objectives. After the strikes were completed the surface ships would again take up the bombardment and maintain a steady fire until about noon. Then on the 31st, initial landings would begin against Carlson (Enubuj), lying  northwest of Kwajalein Island; Ivan (Mellu) and Jacob (Ennuebing) Islands, lying southwest of Roi-Namur. For southern Kwajalein, three other small islands in addition to Carlson were to be captured during the preparatory phase of the operation. These were Carlos (Ennylabegan), Carter (Gea), and Cecil (Ninni) Islands, all lying north of Carlson. On some of these islands artillery could be emplaced for the main assault.

On February 1st, battleships, cruisers and destroyers would conduct a monster bombardment in support of the main landings and air strikes would begin 45 minutes before the men hit the beaches. There would be a cease to the carnage 25 minutes before to allow the smaller islands to deploy their artillery to help support the main assault. With this tremendous bombardment by aircraft, surface ships, and artillery, all to be executed before the first troops hit the shore line, it was hoped that the bitter experience of Tarawa would not be repeated.

For the attack on Kwajalein Island, Corlett decided to land on a narrow front on the beaches at the western extremity, as the reef and surf conditions were more favorable there. He had at his disposal 79 amphibian tanks and 95 amphibian tractors that would transport the first 4 waves to hit the southern beaches. The first with great secrecy would be a pre-dawn landing against Carter and Cecil islands, by one platoon of the 7th Cavalry Reconnaissance Troop. The reconnaissance troop was embarked on two high-speed transports (APD's), along with two platoons of Company B, 111th Infantry. After this the 17th regiment led by Col. Wayne C. Zimmerman would land on Carlos and Carlson islands. The 1st Battalion, 17th Infantry, would hit Carlos while the 2nd Battalion, 17th Infantry, hit Carlson. The 3rd Battalion, 17th Infantry was to be held in reserve, ready to go to the aid of either landing team. While the capture of Carlson Island was in progress, the division artillery, loaded for the most part on amphibious trucks, was to debark and proceed to a rendezvous area offshore. Upon a signal from the commander of the Carlson landing force, the guns were to be moved ashore and into position. This was all done to secure General Arnold's artillery, whom on the night of the D-day along the 145th field artillery battalions would deliver interdictory fire from Carlson on all the principal fortified areas of Kwajalein Island and place counter-battery fire on any enemy artillery that might be emplaced on Burton. They were also to fire general support missions for the infantry. Finally, the 184th on the left and 32nd Regiment on the right would land abreast and advance up the axis of the island. If things looked like they were going well enough and the reserve 17th regiment would not be necessary, they would instead capture the remaining islands of Beverly (South Gugegwe), Berlin (North Gugegwe), Benson, and Bennett (Bigej) Islands in the eastern chain.

There was a hell of a lot of fire power they would face as well. On Kwajalein, 4 12.7-cm, dual-purpose twin-mount guns were divided into batteries of 2, one located at each end of the island. Each battery was protected by 7.7-mm. and 13-mm. machine guns along the nearby beaches. Near each gun were 2 150-cm. searchlights. In addition, the northern end of the island was guarded by a twin-mount dual-purpose 13-mm machine gun on the lagoon shore. Several 7.7-mm. machine guns were in position on the western end and other heavy machine guns were scattered about the center of the island, some mounted on wooden sleds for easy movement to critical points. On the ocean shore were 6 8-cm. dual-purpose guns, divided into 2 batteries of 3 guns each. One battery was east of the tank ditch and the other was opposite the center of the airfield. The first had a 360-degree traverse and could fire either to seaward or landward. The other formed the nucleus of a strongpoint composed of a semicircle of rifle pits facing the beach supported by one heavy and one 13-mm. machine gun, and also included an observation tower, a range finder, and a 110-cm. searchlight. 2 other 8-cm. guns were in position on the lagoon shore, and the blockhouse on the main pier (Nob Pier), which jutted out into the lagoon near the northern tip of the island, had a 13-mm. dual-purpose gun on its roof and firing ports on the ground floor allowing machine guns to fire in all directions.

For the attack on Roi-Namur, Schmidt's 1st phase was to capture the 5 islets near Roi-Namur. The Ivan Landing Group was commanded by Brig. General James L. Underhill, consisting of the 25th Marines under Col. Samuel C. Cumming; the 14th Marines Artillery and Company D of the 4th Tank Battalion. They would seize Jacon and Ivan islands to allow the 3rd and 4th Battalions of the 14th Marine Regiment artillery to deploy. Then they would hit Albert, Allen and Abraham islands where the 1st and 2nd Battalions of the 14th Marine Regiment artillery would deploy. For the main landings Schmidt chose to perform a orthodox amphibious maneuver, simply landing two regiments abreast on a broad front over the lagoon shore. The 23rd marines would hit Roi’s red beach 2 and 3 and the 24th marines would hit Namur’s Green beaches 1 and 2. The 3rd and final phase would see the capture of the remaining islands in the northern Kwajaleins. 

Now that was all for the Americans, but what about the defenders? Admiral Akiyama had recently been reinforced with a number of IJA units such as the 3rd South Sea Garrison from Wake; the 1st South Seas detachment from Mille and Jaluit and the 1st Amphibious mobile brigade from Eniwetok. The reinforcements were deployed mostly on the periphery, as Kwajalien, Jaluit, Maloelap and Wotje had sizable naval garrisons already. The hub of the Japanese military in the Marshalls was at Kwajalein and its main air base at Roi. If you pull out a map, which I do hope many of you do during this entire podcast series haha, especially for Burma it gets really confusing, trust me I know your pain. You can see Kwajalein lies far to the west, with Jaluit, Mille, Maloelap and Wotje kind of acting as buffers. If you were a Japanese commander you would most likely assume any invasion attempt would hit outer islands first and leave Kwajalein as the last one. A quote from one commander, Chikataka Nakajima makes this point "There was divided opinion as to whether you would land at Jaluit or Mille. Some thought you would land on Wotje but there were few who thought you would go right to the heart of the Marshalls and take Kwajalein.”

The three most heavily defended islands were Roi-Namur, Kwajalein and Burton in that order of strength. The defenses of Roi-Namur were organized around a series of seven strong points, 4 on Roi and 3 on Namur, all on the ocean side. Starting from the southwest tip of Roi, the first was located along the southern shore of the west coast. The second and third were to the south and north of the northwest taxi circle. The fourth was on both sides of the wire and stone barriers next to the northeast taxi circle. The fifth, sixth, and seventh were on the northwest, north, and east tips of Namur, respectively. From the lagoon side the approaches were covered mostly by nothing heavier than 7.7-mm. machine guns. Wire entanglements were found at two points—on the beach around the northeast taxi circle on Roi, and on the narrow bit of land connecting Roi with Namur. The beach around the northeast taxi circle also boasted a tank obstacle in the form of large rocks jutting out of a rock wall. Anti-tank ditches had been dug throughout the two islands. On Kwajalein, there was a concrete sea wall along most of the ocean shore and around the northern and western ends of the island. The section at the northern end had posts set into it, probably to act as a tank barricade. East of the area cleared for the airfield was a tank ditch extending halfway across the island, and three smaller tank ditches ran between the ocean shore and the road in the vicinity of the airfield. The lagoon shore was protected by a two-strand barbed-wire fence at the water's edge. The large tank ditch was supported by trenches, rifle pits, and machine guns.

At this point in the war, the Japanese tactical doctrine still stressed beach-line defense that would hinder a proper defense in depth. The Japanese doctrine to fortify beaches would gradually change as a result of the Gilbert-Marshall campaign. IJA General HQ research groups abandoned beach defenses for internal defenses to thwart naval and aerial bombardments, but also to favor concealed positions to thwart flamethrower and grenade attacks. Actually to side track just a bit, there is a book I rather like “The Battle for Okinawa” by Colonel Hiromichi Yahara. If you are interested in how some of the Japanese commanders decided to change to defense in depth, Colonel Yahara was a good case study and the book is interesting. Akiyama had roughly 5000 men on Kwajalein. 930 of these were IJA units, the 1st Company, 3rd Mobile Battalion, plus 2nd and 4th Companies of the 2nd Mobile Battalion of the 1st Amphibious Mobile Brigade. The IJA forces were led by Colonel Asu Tarokichi, commander of the 2nd Mobile Battalion. There also was 250 SNLF of the Yokosuka 4th; 1150 naval troops from the 61st Guard Unit and Akiyama’s headquarters. The rest were not considered combat effective, mostly comprising laborers and logistical units. Most of these units were at Kwajalein itself, with some 345 troops and over 2000 air personnel of the 24th Air Flotilla at Roi-Namur. Three lookout stations were also established on Bennett, Carter and Carlos Islands while an air unit of the 952nd and 160 men defended Burton.

By January 20th, all the preparations were complete in the Hawaiian islands for the grand invasion of the Marshalls. 2 days later, the task forces departed. At dawn on the 29th, the 4 task groups of Task Force 58 and the Neutralization Group arrived to their first assembly positions Aircraft carriers Enterprise, Yorktown, and Belleau Wood successfully neutralized Taroa while while Essex, Intrepid, and Cabot bombed and strafed Roi-Namur. Aircraft from Essex, Intrepid, and Cabot bucked northeasterly winds to bomb and strafe once more the important airfield at that base. Ninety-two enemy planes were based on Roi airfield when the attack developed. Command of the air was seized by American planes at the outset and after 8am, no enemy planes were seen airborne over Roi-Namur. Numerous hits were made on runways, hangars, fuel dumps, and gun positions. Additionally, carriers Saratoga, Princeton, and Langley sent multiple strikes against Wotje, managing to neutralize its airfield. Finally Admiral Sherman’s carriers Cowpens, Monterey, and Bunker Hill launched strikes against Kwajalein. Her airfield and buildings were bombed on the first strike, then she was subjected to strafing and bombing. During the evening Admiral Sherman's group moved northwestward toward Eniwetok to be in position to launch an attack at dawn of D minus 1.

It was not just the navy that smashed the Marshalls, the Army also got a taste. At Kwajalein one flight of seven B-24s dropped fifteen tons of bombs on Roi-Namur and three more tons on Kwajalein Island during the morning and early afternoon. As the carrier planes retired at dusk another seven heavy bombers arrived for a night attack, dropping twenty tons of bombs on Kwajalein Island. At Wotje, flying through heavy overcast, one flight of three B-24s dropped seven tons of bombs, causing fires and damaging the runways. A few hours later a flight of nine B-25s dropped three tons of bombs on the island in a low-level attack and strafed and sank a small cargo vessel in the lagoon. During this late attack carrier planes from the task force mistakenly intercepted the B-25s and shot down two before it was realized they were American planes. Maloelap, Jaluit, and Mille also received land-based attacks during the day. At Taroa, two and a half tons of bombs were dropped by B-25s, which then joined carrier planes in strafing the island. At Jaluit, attack bombers and fighters dropped seven tons of bombs and afterwards strafed the island. Mille was covered all day by twenty fighters, flying in flights of four. Planes that had been scheduled to strike these targets but that were unable to get through because of weather or mechanical difficulty flew over Mille on the way back to American bases in the Gilberts and dropped their bomb loads on the islands of that atoll.The Neutralization group shelled Wotje and Maloelap, leaving the last operational airfield on Eniwetok. Sherman’s fighters and bombers hit the atoll during the morning of the 30th, destroying nearly all its buildings and runways, though a few aircraft managed to escape. The rest of the day would see more carrier strikes and surface bombardments against the Marshalls’ atolls while the landing forces made their final approach towards Kwajalein.

Meanwhile, Admiral Hill’s attack group detached from the main task force, heading for Majuro Atoll. At 11pm 1st Lt. Harvey C. Weeks led a recon platoon on rubber boats to Calalin island, becoming the first Americans to land on any territory the Japanese had possessed prior to WW2. The rest of the recon company led by Captain James Jones landed on Dalap, Uliga and Darrit Islands. Finally, Majuro Island itself. They would find the Japanese had abandoned the atoll perhaps over a year earlier. At the same time Sheldon’s landing force occupied Darrit and Dalop without any opposition and the 1st defense battalion soon arrived to take up garrison duties. To the northwest, the Destroyer transports Overton carrying Troop A and Manley carrying Troop B raced past Turners task force to hit Carter and Cecil islands. Troop B successfully landed on Carter at 6:20am, rapidly securing the island after killing her 20 defenders. Troop A accidently landed on Chauncey Islet at 5:45am and upon realizing they had landed on the wrong island, they left a detachment of 61 infantrymen and then re-embarked at 9:29am. Finally, Troop A landed on Cecil at 12:35pm, finding zero opposition there. On Chauncey, however, the Americans discovered a force of over 100 Japanese hidden in the islet’s center. Half of the enemy force was killed but the Americans would eventually have to withdraw after losing two men. The desperate Japanese would continue to resist until eventually being annihilated a few days later. With the lagoon’s entrance secured, Colonel Zimmerman transferred his two assault battalions to amphibious tractors and sent them towards Carlos and Carlson Islands. 

While Kwajalein, Burton and everly islands were under heavy bombardment, the 1st battalion, 17th regiment landed on Carlos unopposed at 9:10am. From there they quickly attacked the 25 man garrison. To their south, the 2nd battalion landed on the northeastern end of Carlson at 9:12am under some heavy artillery fire coming out of Kwajalein that was quickly suppressed by air and naval bombardment. The men expected fierce resistance, but the Japanese fled, leaving 21 Koreans to be taken prisoner. Honestly pretty good outcome for those poor Koreans. Then General Arnold landed his 5 artillery battalions who got their guns ready by nightfall. Further north, Brigadier Generals James Underhill began operations against Ivan and Jacob islands to secure even more artillery positions. After the preparatory bombardment the marines got aboard their amtracs with a lot of difficulty.

Before the operation, landing team commanders had estimated that their debarkation interval would be about sixty minutes, but this did not pan out. Once the troops were loaded in their assigned landing craft they had to make their way through choppy seas to the LST area for transfer to amphibian tractors. At this juncture all semblance of control broke down. Landing craft were about two hours late in reaching the LST area. Choppy seas and a headwind were partly responsible for the delays. Boat control officers left the tractors in frantic search for the landing craft and failed to return in time to lead the LVTs to the line of departure. Tractors were damaged or swamped while milling around their mother LSTs waiting for the troops to show up. Radios in LVTs were drowned out. One LST weighed anchor and shifted position before completing the disembarkation of all its tractors. The elevator on another broke down so that those LVTs loaded on the topside deck could not be disembarked on time. In short, almost every conceivable mishap occurred to delay and foul up what, under even the best of circumstances, was a complicated maneuver.

Despite the issues, by 9:17 the amtracs were surging forward while LCI gunboats fired rocket barrages. B Company of the 25th marines hit Jacobs at 9:52, easily overrunning the island within 15 minutes. Ivan island had a much rougher surf alongside bad reef conditions that slowed down the amtracs. Company D, 4th light tank battalion managed to land at 9:55am, with Company C of the 25th marines landing on the opposite side of the shore at 10:15am followed by Company A. They linked up and began advancing inland, rapidly destroying a token defense force and securing the entire island by 11:45.

During the early afternoon, the 3rd battalion, 14th marines landed at Jacob Island aboard LVT’s, while the 4th battalion landed on Ivan aboard LCMs. At this point the lagoon entrance was secured, so the 2nd and 3rd battalions, 25th marines re-embarked to land on Albert and Allen. Rough seas delayed them, but the marines were once again on the move. LCI gunboats performed rocket barrages as the 3rd battalion landed on Albert at 3:12, while the 2nd battalion hit Allen 3 minutes later. Both islets were quickly cleared, while G Company landed on the unoccupied Andrew island. The 3rd battalion then assaulted Abraham island at 6:24, securing it by 7:15. With that, the Americans had secured a chain surrounding Roi-Namur and the first phase of the operation was done. Now the Americans would perform the main landings.

Late during the night, Arnolds artillery and Turner’s warships bombarded Kwajalein and Burton while 3 destroyers kept up a barrage upon Roi-Namur. Under the cover of darkness, frogmen of Underwater Demolition Team 1 scouted Roi-Namur and UDT 2 scouted Kwajalein’s beaches. These men made sure there were no obstacles or mines in the way of their landing objectives. This was the first use of UDT’s during the Pacific War. Early on February 1st Kwajalein was hit with an unprecedented bombardment. During one period two shells per second were hitting specific targets or areas in the path of the assault troops. The 14-inch naval shells of the battleships were most effective in piercing and destroying reinforced concrete structures. From the cruisers and destroyers, 8-inch and 5-inch shells ploughed into bunkers and tore up the thick growth of pandanus and palm trees. All together that day, nearly 7,000 14-inch, 8-inch, and 5-inch shells were fired by supporting naval vessels at Kwajalein Island alone, and the bulk of these were expended against the main beaches before the landing. The field artillery on Carlson also joined in the preparatory fire. Its total ammunition expenditure against Kwajalein was about 29,000 rounds. The results of all this expenditure of explosives were devastating. The damage was so intensive that it is impossible to determine the relative effectiveness of the three types of bombardment. The area inland of Red Beaches was reduced almost completely to rubble. Concrete emplacements were shattered, coconut trees smashed and flattened, the ground pock-marked with large craters, coral ripped to splinters. From the carriers Enterprise, Yorktown, Belleau Wood, Manila Bay, Corregidor, and Coral Sea eighteen dive bombers and fifteen torpedo bombers struck the western part of Kwajalein Island while as many fighters strafed the area with machine guns and rockets. All together ninety-six sorties were flown from the carriers in support of the troop landing on Kwajalein Island. As one observer reported, "The entire island looked as if it had been picked up to 20,000 feet and then dropped.”

After 36000 rounds of naval gunfire and artillery, along with sizable air attacks, pummeled the island, LCI gunboats were on the move, tossing rockets into the mix. At 9am, Turner unleashing his landing force. Colonel Curtis O’Sullivans 184th regiment headed towards Beach Red 1, while Colonel Marc Logie’s 32nd regiment hit Beach Red 2. Each beach was covered by a strongpoint, though these were mostly obliterated, with only a few pillboxes surviving. Both regiments landed at 9:30am, finding weak opposition, allowing their artillery support to start smashing 200 yards ahead of their positions. The americans were met with light mortars and automatic fire from some surviving pillboxes, but many were able to take shelter behind the wrecked ruins of a seawall. Meanwhile as more Amtracs pulled up they were hampered by wreckage and debris, causing a congestion. The reefs also hindered where they could approach, but by 11:22 the first four waves of both battalions were ashore, all with 15 minutes. They then began to advance inland against light resistance. Logie’s 1st battalion managed to reach the western edge of the west area by 11:30. Meanwhile O’Sullivan’s 3rd Battalion came face to face with a network of several pillboxes still containing live Japanese in spite of the heavy preliminary bombardment. These were silenced in short order in a series of almost simultaneous actions in which many varieties of weapons were used. Two infantrymen of Company K, Pvt. Parvee Rasberry and Pfc. Paul Roper had landed near the left of Red Beach 1 and had run about 25 yards inland when they came under fire from one of the pillboxes in the area. Quickly taking shelter in a shell hole, they started lobbing grenades at the enemy position about fifteen yards ahead. The Japanese merely threw the grenades back and the volley kept up until a flame thrower was brought forward. That, too, proved ineffective; the flames only hit the box and bounced back. Finally, Private Rasberry got out of his foxhole, crawled to within about five yards of the pillbox and threw in a white phosphorus smoke grenade. This flushed several Japanese from their cover into open positions where they could be taken under rifle fire. Those who weren't hit ran back to the pillbox. Rasberry threw white phosphorous grenades until he had none left, by which time about eight of the enemy had been killed. At this juncture, T. Sgt. Graydon Kickul of Company L was able to crawl up to the pillbox and on top of it. He emptied his M1 rifle into it, killing the remainder of the Japanese inside. To make doubly certain that the job was done, an amphibian tank was then brought forward to fire both its flame thrower and its 37-mm. gun into the aperture.

Meanwhile Logie’s 1st battalion got within 250 yards of Wilma road by 12:20. An hour later they fell upon a network of pillboxes. To the north O’Sullivan’s 3rd battalion ran into tough resistance again, but managed to link up with Logie’s men at Wilma Road by 2:50pm. Behind the battalions were follow up battalions who mopped up the area and the reserves secured the beachheads. Logie and O’Sullivans men then fought their way to Kwajaleins airfield. Lucky for them the Japanese had not established a defensive line across the width of the island, instead the bulk of them retired eastward, for their commander Admiral Akiyama had run into an early tragedy. Akiyama had left his bunker to observe the front line and was killed by an artillery shell. At 3:25, the 1st battalion was relieved by the 2nd battalion who began attack against the strongpoint at Canary

Some of these positions, which extended along each side of Wallace Road, were defended by Japanese who ducked and crawled through rubble heaps and bunkers in such a way that Lt. John L. Young, commanding Company E, became convinced that they were using connecting tunnels. For an hour the fighting persisted, but not more than ten enemy dead could be counted above ground. Company E continued through a litter of small works, moving so slowly that it was necessary to commit Company F, which undertook a flanking movement at the left. The maneuver was intended to cut the strong point off, but the company promptly ran into fire that slowed its advance to about fifty yards in thirty minutes. It then became clear that the whole movement had been stopped. The attack was consequently broken off at 1800 and defensive positions were organized for the night. To the north, O’Sullivan’s 3rd Battalion ran into large underground shelters and defenses. Their advance was temporarily blocked by a fuel dump ignited by artillery fire, but they eventually pushed on another 500 yards before halting at 18:00 for the night. 

Meanwhile Logie’s 2nd battalion broke off their attack halfway up the length of an unfinished runway and dug in for the night. 

By the end of February 1st, approximately 450 of the dead Japanese were counted  in the zone of the 184th, and this regiment also was responsible for the capture of ten of the eleven prisoners taken. A large share of the enemy casualties was attributed to the heavy bombardment from ships and aircraft and from artillery based on Carlson. Estimates made by assault troops and by others, including doctors following the assault, indicated that the preparatory bombardment caused from 50 to 75 percent of all Japanese casualties on Kwajalein Island. It truly was a colossal bombardment. The Americans suffered 21 deaths and 87 wounded.

Over on Roi-Namur, Admiral Conolly’s LSTs entered the lagoon at first light to provide the amtracs an easier ride. Naval ships, artillery and aircraft began smashing the island. The marines saw some delays, but Colonel Colonel Louis Jones’ 23rd Marines began their run to Roi at 11:50. Covering them, amphibian tanks sought hull defilade positions and concentrated their 37mm fire on the Wendy Point blockhouse, which could deliver flanking fire on the assault waves. The 1st and 2nd Battalions hit the beaches at 11:57 landed and immediately began to push 300 yards inland. Meanwhile Colonel Franklin Hart’s 24th Marines bound for Namur were assigned the tractors of the 10th Amphibian Tractor Battalion that had participated in the preceding day's actions. The troubles that had beset the 10th Amphibian Tractor Battalion on D-Day were titanic. They had been launched too far from the line of departure in the first place. They had to buck adverse winds and unexpectedly choppy seas. Radio failures had tremendously complicated the problem of control, causing still further delay and much unnecessary travel through the water. All of this spelled excessive fuel consumption and many of the tractors ran out of gas before the day was over. For an LVT to run out of fuel in a choppy sea was usually disastrous. This model, the LVT-2, shipped water easily and its bilge pumps could not be manually operated. Thus, when the gasoline supply was gone the vehicle could not be pumped out and usually sank. In addition, many of the tractors of the 10th Battalion had not been released from their duties on D-Day until after dark, were unable to get back to their mother LSTs for refueling, and had spent the night on various outlying islands. Thus, as the hour for descending on Namur approached, the 24th Marines could muster only 62 of the 110 tractors that had been assigned to them and a hurried call was sent out for LCVPs to make up the difference. After some scrambling, the 2nd and 3rd battalions were reorganized and on their way to Namur.

Hart’s 2nd battalion hit Beach Green 2 at 11:55. They faced anti-tank ditches across the narrow beach, causing a large congestion. Hart’s 3rd battalion made it to Green 1 at 12 and his K and I companies immediately advanced north. Meanwhile Jone’s battalions secured Wendy Point facing no opposition. Encourage by the lack of resistance, the Marines began a rather disordered dash across the island. The stormed across the runway without orders and all guns blazing. Tanks and infantry hastily charged in the disorder, successfully driving the surviving and terrified Japanese north. Jones managed to gain control over his units and brought them back to assembly points to coordinate further attacks. The “re-assault” of Roi kicked off at 3:30 against a dazed enemy still trying to recover from the first attack. The 2nd battalion pushed north towards Estelle point while the 3rd battalion hit Nancy point. Enemy resistance was being rapidly annihilated, Estelle point was secure by 5pm, while Nancy Point would be taken by 6pm. After Nancy point was secured, Jones declared Roi secure.

Meanwhile Harts F company unknowingly breached a torpedo warhead bunker and began throwing satchel charges into the hole. The structure was obliterated by a massive explosion that would detonate two other ammunition bunkers nearby. Blocks of concrete, palm trees, wood, torpedo warheads, and other debris rained down over the island, covering most of the island with smoke and dust. 20 Marines were killed and 100 were wounded. The enormous explosion disrupted the 2nd battalions assault, causing a delay. Hart’s 3rd battalion enjoyed more success, but heavier resistance as the Japanese defenders took advantage of all the rubble and dense brush tossed around to hide behind. By 7:30pm, Hart ordered his men to dig in and during the night the Japanese began their classic infiltration tactics. The green troops amongst the men began indiscriminately firing throughout the night. The next morning, light tanks broke a Japanese counter attack, as the Marines advanced 50 yards. Hart then launched his main attack at 9am,with the 3rd Battalion rapidly securing Nora Point by 11:00am. Tank support for the 2nd Battalion arrived an hour late, but they still managed to push towards Natalie Point by 12:15, where the two battalions linked up. Mop up operations continued in the rear, but the island was declared secure at 2:18. For their first operation, Schmidt’s 4th Marine Division suffered 206 killed, 617 wounded and 181 missing. 3472 Japanese would be found dead, with 51 captured and 40 Korean laborers surrendered. 

To the south, after aerial, artillery and naval bombardment, Corlett launched a tank supported attack at 7:15am. O’Sullivans 2nd battalion advanced north against weak resistance while Logie’s 2nd Battalion continued to fight through the Canary strongpoint. Advancing through destroyed pillboxes with tanks at the forefront, O’Sullivans men were able to reach Carl Road on the eastern end of the airfield by 10:40am. Meanwhile Logie’s men reduced the Canary and advanced rapidly until they reached the deadly Cat strongpoint. Here they faced tiers of well-concealed defensive works, taking many lives until they also reached Carl Road at 10:40. The Americans were now facing the main defensive system of the island. In front of it lay a deep tank trap, connected to long rifle trenches. Beyond this was anti-tank ditches and an elaborate organized set of defensive positions called Corn strongpoint. They were in for a hell of a time.

Operation Flintlock went off with a terrifying bang seeing the combined firepower of land, air and sea tossed against the Marshall islands. The Americans had made easy and quick work of the smaller islands, but now we're face to face with a truly formidable defensive position that was sure to cause them real headaches. 

- 114 - Pacific War - Fall of Shaggy Ridge , January 23-30, 1944

Last time we spoke about the operations HA-GO, U-GO and the continued drive against Shaggy ridge. Lt General Mutaguchi Renya sought to invade India and was continuously scheming to drag the rest of the IJA on this rather insane endeavor. Yet the allies also tossed their own operations in the Burma theater greatly disrupting the Japanese planners and achieving numerous objectives. Over in New Guinea, Vasey launched an offensive against the Kankeiri saddle, designated operation cutthroat. Meanwhile General Nakano 's men were in a dire situation with the allied seizure of Sio and Saidor. Multiple Japanese units found themselves all doing the same thing, retreating further north. It seemed no matter what defensive lines they established, the allies kept their advance over land and periodically amphibious assaults their flanks and rear. The formidable defenses region of Shaggy ridge was not going to hold up against the allied advance much longer.

The Australian advance overland and Saidor operation had paid great dividends over and above the establishment of forward military base construction. The allies had formed a giant wedge between a significant residue of the Japanese fleeing the Finschhafen area. General Adachi commanding the 18th area army was facing a nightmare. Prior to the American landing, he had visited the 51st division HQ at Kiari and then traveled overland to the 20th Division over at Sio. He was fully aware of the hardships facing both forces. Meanwhile news of the Saidor landings hit Rabaul creating a massive debate. Senior officers sought to bring over all available troops to try and retake the town. Others sought to save as many troops as possible for a defense of Wewak, considering it the next main allies target. General Imamura favored bypassing Saidor altogether and withdrawing over inland trails. Thus Adachi appointed General Nakano to take charge of the withdrawal to Madang, and ordered 8 other companies to cross the Ramu valley to Bogadjim to harass the Americans at Saidor. These were purely defensive maneuvers. The Japanese also faced the daunting task of how to evacuate large numbers of troops from the 20th and 51st divisions from the impending allied trap. Nakano took the lead getting the 20th to retreat up the coast while the 51st worked their war over the inland trails. Nakano would soon be forced to abandon the plans and ordered both to pull into the interior to retreat towards Madang, nearly 200 miles away. This would mean the exhausted, starving and sick Japanese had to battle through the jungles, ridges, rivers and other horrors of the Finisterre range. 

Meanwhile Saidor was easily secured by the 32nd division, the Australian 7th division advanced through the Ramu Valley and came face to face with Shaggy Ridge. Shaggy ridge had been transformed into a heavy fortified position with numerous nasty features such as the Kankeiri saddle, Pimple, Intermediate snipers pimple, Green snipers pimple, Prothero 1 and 2 and so forth. During the first weeks of January the Australians made very little headway against the honeycombed Japanese defenses. Their air forces were called in numerous times to plaster the ridgelines in a 3 day assault designated Operation Cutthroat. On the 18th of January, B-25s from Nadzab and Port Moresby would drop 500 lb bombs all over the defenses. On the 21st P-40s strafed and bombed the area and this was met with some reorganizing of the ground forces. The 15th and 18th brigades relieved the exhausted 21st and 25th. Brigadier F. O Chilton began the new job by opening heavy artillery up on Prothero I. Captain T. L James with the 2/2 pioneer battalion described the attack on January 20th “At 1000 hours we met 2/12 Infantry Battalion at the appointed rendezvous, where I met their CO., Lt.-CoI. C. F. Bourne. We did not stay long at the rendezvous but formed up and commenced the long approach march. It was a gruelling day. The long single file moved silently up the deep ravines, scaling cliff-faces with the aid of ropes and lawyer vines. It took us the entire day to cover the four mile approach. In one spot that was almost impossible to traverse—a steep-sided cliff—they rigged lawyer vines between trees to act as a handrail and allow us to pull ourselves up." Despite the harsh conditions and fierce resistance, the Australians got atop Canning saddle and then forded the Mene river and drew near the village.

Colonel Matsumoto’s men were now trapped between the 2/9th battalion advancing from the Pimple and the 2/12th battalion from Prothero 1. To the east there was the 2/10th battalion about a mile away from the main Japanese defensive position along the Kankeiri saddle. On the 22nd, the 2/12th dispatched D company who advanced between Prothero1 and Prothero 2. At 10:40am they began to fire their artillery upon Prothero 2 and at 11:15am a platoon tried to progress but was held down by Japanese snipers and machine gun fire. A company came through D company to advance along Shaggy ridge until 3:30 pm once they took were held down by Japanese fire. Then a single australian section rushed forward led by Bren gunner Private Bugg. His team hit a Japanese machine gun crew from just 30 yards away. He seized a toehold quickly upon Prothero 2. After some bitter fighting Prothero 2 had fallen into allied hands. Meanwhile to the south the 2/9th sent a patrol out on the 22nd who found pill-boxes at McCaughey’s knoll occupied with Japanese gunners. At 10:45am as allied artillery hit Prothero 2, Captain Taylor led a company of the 2/9th and assaulted McCaughers knoll. They were quickly pinned down, but by 1:15pm word reached them that Prothero 2 was captured and that the entire battalion was to push along Shaggy ridge. During that afternoon Taylor took his company to the western side of Shaggy ridge, getting ready for a new flanking maneuver against McCaughey’s knoll. The men fought their way up the knoll cleaning up pillbox one after another, capturing McCaugheys knoll by nightfall. It would cost them 8 men wounded.

More than 100 dead Japanese were found over the Prothero-Shaggry ridge area when mop up crews did their work. Meanwhile 2/10th kept up the pressure in the east. On the 22nd A Company led by Lt Gunn seized a foothold on Faria Ridge and, prompting the enemy by late in the afternoon, to abandon Cam's Hill, which was occupied by the 2/10th by 5.20 p.m. During the night and early morning of january 23rd, two counter attacks were launched by the Japanese.  At 2.40 the forward troops of A Company on the ridge were attacked from the south but the attack was repulsed with no casualties. After this the Australians moved down the track towards Kankeiri. Captain Haupt’s B Company of the 2/12th advanced down the track from Prothero 2. By 6pm they were atop the saddle around Crater Hill when they came across a Japanese gun position containing 150 rounds of 75mm ammunition. Half an hour later they ran into some resistance from slopes atop Crater Hill. They would pull back to the Kankeiri saddle to dig in for the night. 

The 2/10th then dispatch D company led by Captain Kumnick to advance along the Faria Ridge. They made it 1500 yards before running into a well entrenched position that held them down with machine gun fire. During the night however the Japanese abandoned their entrenchments for Cam Hill allowing the 2/10th to establish itself in a position roughy 1200 yards southeast of Crater Hill the next day. On the 24th, the 2/9th took over the responsibility for Shaggy Ridge up to Prothero 2 allowing the 2/12 to advance up Kankeiri.  Small patrols from company B of the 2/12th reached the top of Crater Hill that day finding an enemy position on the southern slopes. On the 25th, the 2/12th and 2/10th probed enemy defenses on all sides of Crater Hill looking for decent approaches to attack. This led to several skirmishes, seeing both sides suffer casualties. One patrol led by Lt Coles of the 2/2nd pioneers, surveyed the Paipa mule track along the valley of the Mindjim, firing upon small bands of retreating Japanese. The Australians gradually converged to attack Crater Hill, but Matsumoto’s defenders put up a valiant effort to repel the assaults.

On the 26, Brigadier Chilton ordered Companies C and D of the 2/9th and Companies C and B of the 2/12th to assault Crater Hill. This saw companies C and D of the 2/9th perform a outflanking maneuver to the north tip of the Mindjim valley to hit the enemy's right flank, while Companies C and B of the 2/12th held the enemy down. Captain A. Marshall's C company led off at 10.35 a.m, passing from Shaggy Ridge through Kankirei Saddle and then to the north, with Captain Taylor's D company following to provide flank protection. By midday Marshall reported that he had advanced some 600 yards and passed through several old and abandoned positions finding no enemy. Cautiously he pushed on, at 5 p.m. he reached the summit of 4100. The main enemy position was to the south between Marshall and the 2/10th and 2/12th Battalions. Leaving Taylor to occupy the summit of 4100 Marshall advanced south towards Crater Hill in an attempt to surprise the enemy from the rear . He met them about 300 yards south-east from the summit just at dusk. The leading platoon attacked along the usual razor-back but withdrew because of heavy machine-gun fire. At 7 p.m. Marshall sent Lieutenant White's platoon round the right flank but approach from this flank was also very difficult and White was killed. By the nighttime, they had successfully surrounded Matsumoto’s weakened defenders.

Matsumoto’s defenders had established extremely formidable positions and had a large number of automatic weapons at their disposal. Matsumoto was ready alongside his men to make a final stand. Basically a siege of Crater Hill began and would only end after 5 brutal days. The first two days saw Chilton order the 2/9th take responsibility for the southern slopes of 4100 and Kankeiri saddle, while the 2/12th held Protheros and Shaggy ridge, and the 2/10th maintained pressure on the south-eastern slopes of Crater Hill. Skirmishes borke out everywhere, as the artillery smashed Crater Hill. Captain Whyte of the 2/4th field regiment fired 2000 shells, shattering trees, which unfortunately created more timber obstacles for the advancing Australians. At 9.30 a.m. on the 29th, 19 Kittyhawks dive-bombed Crater Hill, followed by ten minutes of artillery fire. At 1.30 p.m. the artillery laid down a barrage and machine-gun fire covered an assault on Crater Hill from the west by Captain Daunt's company of the 2/9th . The leading platoon attempted to rush the enemy position up a very steep and open slope but the Japanese, entrenched on a razor-back, were too strong and drove them back. The Australians also had the bad luck to be shelled by their own artillery. Each time they performed an assault, the stubborn Japanese held firm. Finally on the 30th with the help of some heavy rain Matsumoto decided to evacuate during the night. Matsumoto and the remnants of his force withdrew towards Yokopi and Kubenau valley. After dawn on the 31st, Australian patrols found Crater Hill abandoned and it was a horror show. They found a ghastly mess. At least 14 dead were found and evidence of burials alongside them. The 2/9th and 2/10th advanced occupying the hill on February 1st.

With that, Shaggy Ridge and the Kankeiri saddle had finally fallen. Chilton sent out patrols to pursue the retreating Japanese and perform mop up operations. By February 6th his forces managed to seize Paipa and Amuson. The Australians had suffered 46 deaths, 147 wounded while the Japanese figures were estimated at around 500 casualties. Meanwhile, Brigadier Hammer had also carried out two operations during this time period. The first was a diversionary attack against the Spendlove Spur held by elements of the 5th company, 80th regiment. This was carried out by Captain Kennedy company of the 24th battalion, whom managed to surprise the Japanese and quickly seized Cameron’s Knoll. On January 30th, the 57/60th battalion led by Lt Colonel Robert Marston departed Ketoba and along another company led by Captain McIntosh assaulted Orgoruna, Kesa and Koba. The Australians would find Orgoruna and Kesa undefended..

Lt Marston ordered Major Barker 's 8 company to patrol Koba, and they would enter Koba on  February 1st finding nothing, so they  pushed on towards Mataloi 2 . There were signs of very recent occupation and, 200 yards along the track , they were ambushed. Barker brought heavy fire down upon the Japanese ambush position and managed to capture Koba that night. On the morning of the 3rd, about 400 yards east of Koba, Barker again struck a Japanese ambush position. They quickly outflanked the enemy who withdrew through Mataloi 2 towards Mataloi 1 . By the time Mataloi 2 was occupied at 6.30 p.m., there was not enough time to hit Mataloi 1 nor to allow adequate consolidation of Mataloi 2 before dark. At 9.30 p.m. the Japanese counter-attacked from the direction of Matalo 1, commencing the assault with a heavy mortar bombardment. As Mataloi 2 could be defended from three sides, Barker decided that he could hold the area best from high ground to the south which would also be out of range of the enemy mortars. Accordingly he ordered a withdrawal and departed with his headquarters and one platoon. Apparently the orders did not reach the other platoons who were encircled while the remainder of the company was withdrawing to Koba. Long-range enemy machine-gun fire was directed at Kesa at the same time as the counterattack developed at Mataloi 2. The 57th/60th pulled out concluding their little raid. Now Brigadier Hammer’s 15th were getting ready to pursue Matsumoto’s detachment who were fleeing to Kwato. But that is all we have for New Guinea, as were are moving back over to New Britain.

Last time we were over in New Britain, the Americans had captured Hill 660, and were unleashing patrols to try and figure out where the Japanese were concentrating. Now they sought to secure the Borgan Bay-Itni river line. Meanwhile on the other side, General Matsuda’s battered men had begun a retreat heading east via the Aisalmipua-Kakumo trail towards Kopopo. They also received reinforcements in the form of the fresh 51st reconnaissance regiment who took up the job of rearguard. The Japanese knew the terrain better than their American counterparts, thus held distinct advantages. They knew good grounds to put up defenses and how long they could hold out in such places until they should retreat. The Americans did not enjoy good maps, they had to painstakingly explore where they went. They relied on native reports on where to go, but in the end they were like explorers jumping into jungles, atop mountains and a hell of a lot of swampy terrain. The rainforests could be so dense, patrols could be moving yards from another and not know it, imagine trying to find hypothetical objectives in such places?

 

Thus an enormous amount of vital patrolling was performed, beginning on January 19th with Captain Ronald Slay’s men of L Company 1st marines. They advanced past Mt. Gulu, Langla volcano and Munlulu before heading down the saddle of Mt. Tangi. They managed to ambush a group of 20 Japanese being led by 8 armed natives, who fled east after 6 Japanese were killed. Slay took his men across the east-west government trail, only finding some Japanese telephone wire, which was severed. On the 22nd two patrols each consisting of a reinforced company departed the airdrome perimeter to converge from two directions along the trail junction Captain Slay’s men discovered. The first was elements of the 1st battalion, 1st marines led by Captain Nikolai Stevenson, the other was led by Captain Preston Parish with elements of the 7th marines who took landing crafts to Sag Sag, the terminus of the east-west Government trail. Parishes men would bivouac around 1.5 miles inland near Aipati on the 24th while Stevensons men headed south of Mt Gulu. Both patrols found no Japanese, but Parish gained some valuable intelligence from a native village, who indicated there had been several Japanese parties around.

On the 23rd, Stevenson and his men ran into a concealed machine gun crew 30 yards near Mt Langla. The Americans scrambled to fight back at an enemy they could not see. They did not lose any men, but had no idea if they hit any Japanese either. They continued their advance afterwards and would be ambushed again, this time 1500 yards south of Mt Munlulu. This time they seemed to be facing a force of platoon strength. By the 25th Stevenson and his men were pulling back to Mt Gulu and were relieved by another incoming patrol led by Captain George Hunts K Company, 1st marines. Meanwhile Parish’s patrol continued east as the natives had indicated to them where the Japanese might be retreating through. On January 27th Hunts company ran into Parish’s and both shared information and went in opposite directions hoping to hunt down nearby Japanese units. Hunt set off to the location where Parish’s men had run into a Japanese ambush previously, expecting to find at least 50 Japanese. At 7am on the 28th, Hunt’s men came across an outpost line and engaged it for hours, seeing 15 casualties. Hunt pulled his men back out of mortar range and the Japanese swarmed upon them forcing the Americans to perform some heated rearguard actions. Overall these patrols amongst others allowed the Americans to get a better picture of the terrain and concentration of the enemy.

For two weeks the American patrols searched for the enemy headquarters running into countless skirmishes, mostly against the forces of Colonel Sato Jiro. By the 27th, Matsuda had reached Kokopo and received new orders from General Sakai that he was to take the men further on towards Iboki. Colonel Sato was to again provide the rearguard. This allowed the Americans to seize Nakarop, a placed their translators had mistranslated from Japanese documents as “Egaroppu”. It had been the nerve center of General Matsuda’s operations. They found countless abandoned tents in bivouac areas, the village contained native and Japanese built structures. There was a huge sign saying "Matsuda Butai Army Command Principal Place." There were traces of elaborate radio installations recently removed containing an American-made telephone switchboard labeled "Glory Division." It would turn out Matsuda's personal quarters, however, were actually located off the main trail roughly midway between Magairapua and Nakarop, its approaches so skillfully concealed that patrols did not find it until several days later. Well camouflaged bivouac areas also infested this entire region. With the capture of Matsuda’s former headquarters, all patrols were combined into the Gilnit Group led by the legendary Colonel Chesty Puller. Puller pointed his force in the direction of the Borgen Bay-Itni River to clear it out. They departed Agulupulla on January the 30th as the 5th Marines relieved the 2nd battalion, 1st marines to attack the Iboki area. Attempts were made at leapfrogging, using landing craft to hit places hoping to trap Japanese during the advance.

The landing craft were operated by the Boat Battalion, 533d Engineer Boat and Shore Regiment, of the Army's 2d Engineer Special Brigade. They were made available to carry out the amphibious phase, and the division's little Cub artillery spotter planes for observation and liaison. Rough seas frustrated the first landing attempt at Namuramunga on February 4th, forcing two patrols from the 2nd battalion to proceed overland from Old Natamo via a coastal track. They got as far as Mambak killing a few stragglers and taking 3 prisoners. The next day another patrol landed at Aliado and advanced down the coastal track to the mouth of the Gurissa river through Kokopo and Gorissi. By the 10th of february they managed to kill 16 stragglers and grabbed 6 prisoners who they brought back to the Borgen Bay perimeter. Meanwhile the 3rd battalion advanced into Gorissi by boat on the 12th and setup a radar station. They then dispatched a patrol to the EI river on the 16, finding it impassable. Another patrol was sent to leapfrog around the Arimega Plantation on the 19th. It was seized quickly and now the Americans were very close to Iboki.

 

Meanwhile Sato reached Kokopo, but did not linger long and continued on to Karai-ai by February 12th. That day the 3rd battalion, 5th marines, aware of the Japanese course, set up an advance base at Gorissi. Now 20 miles separated the Japanese rearguards from their pursuers. Sato and his men would reach Iboki by February 16th, while the Marines were fording the El river, 30 miles behind. It would take them 5 additional days to reach Karai-ai. To the south Puller’s group had reached Gilnit and Nigol on the 10th, finding no enemy. These actions saw the Americans secure the western half of New Britain. 2 days later, Company B of the 1st Marines landed on Rooke Island where they set up a radar installation. They also had to patrol the islands to see if any Japanese remained upon it. They fanned out, running into native villages who offered them fresh fruit. They would come across machine gun emplacements, abandoned bivouac areas and some medical stations, but no Japanese. The enemy had clearly evacuated the island

 

All the way back over at the Arawe area, Major Komori had received new radios on February 5th enabling him to resume communications with the 17th divisional HQ. He received a gloomy report  “At present, the airfield is covered with grass 4 to 5 [feet] high. The airfield, 200 m [sic] in width 800 m in length, will be serviceable only for small airplanes. However, it will take quite some time to develop it. Consequently, I believe that it will not be of great value.” Knowing about Matsuda’s withdrawal, he began casting envious eyes in the same direction. On February 8, he hinted more broadly to that effect: “As has been reported, the value of Merkus airfield is so insignificant that it seems the enemy has no intention of using it… Due to damage sustained by enemy bombardments and to the increased number of patients, it becomes more and more difficult to carry out the present mission… It is my opinion that as the days pass, replenishment of supplies will become more and more difficult and fighting strength will be further diminished; our new line will be cut off and consequently leave us with no alternative but self-destruction.” Divisional HQhowever was not pleased with this and sent a telegraphic response the following day ordering him curtly to continue his mission. Komori would write in his diary that day "Wondered what to do about the order all night long. Could not sleep last night… I felt dizzy all day today." Fortunately for Komori, on February 17th Sato was ordered to occupy key positions at the Aria river’s mouth to help supply him by land. This allowed Komori to begin his retreat north on the 24th while Sato evacuated the Iboki stores to Upmadung. Komori’s departure would be just in the nick of time as the Americans dispatched two tank platoons to clear out the airfield area on the 27th. They would find zero enemy resistance and this would put an end to the Arawe operation. And that will be all for today for New Britain as we are going to be covering some big allied planning. 

 

Over in the southwest and south Pacific Areas, General Douglas MacArthur continued his plan to drive back towards the Philippines. This would be done via amphibious operations along the north coast of New Guinea. His next main target was the Vogelkop Peninsula, then the Palau Islands, then the invasion of Mindanao. This would also see the Japanese lines of communications to the Dutch East Indies cut off. Yet before all of this he needed to capture the Hansa Bay area of northeastern New Guinea and then Hollandia in the Dutch part of New Guinea. This action would allow his forces to bypass the Japanese stronghold at Wewak. Meanwhile there were the ongoing efforts to reduce Rabaul, and to continue that he still had to capture the Admiralty Island and Kavieng, which would completely cut off Rabaul. The planners for the south, southwest and central Pacific Areas met at Pearl Harbor on January 28th. However the Joint Chiefs of Staff decided to delay MacArthur’s invasion of the Admiralties and Kavieng pushed it to April 1st. They had determined it was better to prioritize the invasion of the Marshall islands in the central pacific. This delay would further delay most of the southwest pacific operations along the New Guinea coast.

Meanwhile Admiral Kusaka and General Imamura had sent the bulk of the 230th regiment and the recently arrived 1st independent mixed regiment to New Ireland. The 2nd battalion, 1st independent mixed regiment was sent to the Admiralties on January 25th, joining up with Colonel Ezaki Yoshio’s 51st transport regiment. Then the 1st battalion, 229th regiment was sent to the Admiralties on february 2nd. These were last ditch efforts by the Japanese to secure a very desperate lifeline for Rabaul. No offensive could be mounted for at least 3 months, thus the Japanese were given ample time to reinforce and strengthen their defenses.

Admiral Halsey also had plans to invade the St Matthias Islands as a preliminary for the attack upon Kavieng, and this like MacArthur's plans were thrown into disarray. In view of all of this MacArthur suggested to Halsey a new plan, codenamed Operation Squarepeg, to seize the Green Islands and establish a new PT boat and or air base there. With that in hand they could project air and naval power further against Rabaul and perhaps even as far as Truk. However many of the officers did not believe any of this would significantly isolate Kavieng and Rabaul. Furthermore, they believed it doubtful that fighters stationed at a base in the Green Islands would even be able to cover Kavieng. Admiral Wilkinson, with the backing of Admiral Fitch and General Geiger, suggested that the proposal be abandoned, and that plans be laid for a landing either at Borpop or Boang Island. On 28 December, however, after analyzing the situation, Colonel William E. Riley, Admiral Halsey's War Plans officer, made the following observation: “There is no doubt but that the occupation of this area [Borpop] and the utilization of air facilities thereat would assist materially in the neutralization of both Rabaul and Kavieng. However, the grave possibility that such an operation would result in the employment of approximately two divisions and additional naval support, not now available and will--in all probability--not be made available in time for this type intermediate operation, makes it necessary to eliminate Borpop as a possible intermediate operation… Though Green Island is not as far advanced as Boang Island, yet it is quite possible to provide fighter cover for strikes on Kavieng. In addition, dive bombers, based on Green Island, can operate most effectively against shipping at Kavieng.”Thus Halsey elected to go ahead with Operation Squarepeg anyway because a fighter umbrella could be tossed over the Green Islands during an amphibious invasion, something that would not be possible for Boang or Borbop.

Halsey’s staff went to work planning the amphibious landing. It would be carried out by elements of General Barrowclough’s 3rd New Zealand Division. PT 176 and PT 178 of Lieutenant-Commander LeRoy Taylor’s Torokina Squadron conducted hydrographic reconnaissance of the islands on January 10th and discovered the southern channels near Barahun island were the most suitable. 300 men of the 30th New Zealand battalion led by Lt Colonel Frederick Cornwall got aboard the APDs Talbot, Waters and Dickerson, covered by the destroyers Fullam, Bennet, Guest and Hudson led by Captain Ralph Earle. They landed on Nissan Island and performed a survey finding a promising airfield site. They also discovered there were no more than 100 Japanese at a relay station alongside 1200 native Melanesians. Pretty sure I said this before in the series, but I will repeat it. Melanesians are one of the predominant indigenous inhabitants of the Melanesian islands that are found in the area spanning New Guinea to the Fiji Islands. Something pretty neat about them, along with some indigenous Australians, they are the few groups of non-Europeans to have blond hair. The Melanesians were so friendly to the New Zealanders and so hostile to the Japanese that it was decided to omit the usual preliminary naval and aerial bombardment for the landings. 

Now over in the Central Pacific plans to invade the Marshall were underway, even before the successful liberation of the Gilberts. The operation was codenamed Operation Flintlock, and Admiral Nimitz assigned the 4th Marine division, reinforced with the 22nd marine regiment and Army’s 7th division to train intensively for amphibious warfare. They were deemed Tactical Group 1, led by Brigadier General Thomas Watson. They would be backed up by a whopping 23 aircraft carriers, 15 battleships, 18 cruisers and 109 destroyers. Yet things had certainly changed since 1942, the American Navy was packing overwhelming heat. Admiral Spruance, now commander of the 5th fleet, would hold the highest operational command for Operation Flintlock. Admiral Turner would be commanding task force 51 and the Joint Expeditionary Fleet and General Holland Smith would be commanding all the expeditionary troops. General Smith's position in the chain of command in relation to Admiral Turner was made much clearer than it had been during the Gilberts operation. Simply put he was put in direct command of all landing forces and garrison forces once they were ashore. The troop commanders of each of the landing forces, the 7th and 4th Marine Divisions, were expressly placed under Smith until such time as Admiral Spruance should determine that the capture and occupation phase of the operation had been completed. However, Smith's authority as commander of expeditionary troops had one limitation. It was recognized that "the employment of troops, including the reserve troops engaged in the seizure of objectives, is subject to the capabilities of the surface units to land and support them," thus any directives issued by Smith as to major landings or as to major changes in tactical plans had to have the approval of Turner before they could be issued. To this extent, the expeditionary troops commander was still subordinate to Turner. They would also be supported by Rear Admiral Marc Mitscher’s fast carrier force, task force 58 and Admiral Hoovers land based air forces, including the 7th air force and other Navy air forces. So yeah, America was coming in overkill.

Nimitz’s original plan was to advance into the Marshalls by simultaneously hitting Kwajalein, Maloelap and Wotje. Together these contained 65% of the aircraft facilities in the island group, leaving the 35% remainder on Jaluit and Mille. Jaluit and Mille could be neutralized and bypassed. Yet after facing the difficulties during the Gilberts operation, Nimitz decided to also bypass Maloelap and Wotje as well, so he could concentrate all his forces against Kwajalein. General Smith and Admirals Spruance and Turner opposed this, arguing that sailing into Kwajalein would be too exposed if Maloelap and Wotje were left unoccupied. 

Nimitz 'new plan would see General Corlett’s 7th division hit the southern group of islands in the atoll, including Kwajalein island, while Major General Harry Schmidt’s 4th marines would hit Roi-Namur and the other northern islands of the atoll. Task Force 52, would transport the 7th Division while Rear Admiral Richard Conollys task force 53 transported the 4th marines. After some meetings, Spruance managed to secure the invasion of Majuro, which would be carried out by Lt Colonel Frederick Sheldon’s “Sundance” Landing Force. They consisted of the 5th amphibious corps reconnaissance company, the 2nd battalion, 106th regiment and the 1st defense battalion. Spruance wanted to make the atoll a fleet base, so airfields could be constructed to help cover the line of communications to Kwajalein. To support the main landings, Mitschers fast carrier force was going to smash the enemy aircraft and air facilities at Wotje, Maloelap, Roi-Namur and Kwajalein while his vessels simultaneously coordinated with Turners cruisers and Rear Admiral Ernest Small’s Neutralization group task force 50.15 to naval bombard them as well. The main threat that needed to be neutralized quickly was Eniwetoks airfield. Meanwhile Hoover’s land based aircraft would help neutralize Mille and Jaluit and help smash the other islands and shipping.

Throughout November and December, two atolls would receive more attacks than the others. Mille closest to the Gilberts, thus much more accessible, earned the lionshare of attention. Maloelap with its large air facilities had to be kept under constant surveillance and attack, thus she came second. Beginning on December 23rd, aircraft based out of the Gilberts began increasing air strikes against the Marshalls.  On Mille between November 24th to December 18th, 106 heavy bombers dropped 122 tons of bombs over the runways and facilities. The next week bombers and fighters began attacking Mille’s fuel dumps, leveled all buildings, destroyed 11 grounded aircraft and another 13 in the air. Mille was neutralized and the Japanese would abandon its airfield by January. The damage dished out to Maloelap was extensive, but not as crippling. Her runways were not entirely put out of operation. From January 11th to the 25th, B-25’s destroyed her ground installations, but still her airfield remained operational. On January 26, 9 B-25s, followed by 12 P-40s, flew into Taroa for a low-level attack. The B-25s destroyed 9 interceptors on the ground and 5 more after they were airborne. The control tower and two other buildings on the airfield were set afire and four tons of bombs were dropped in fuel dump and dispersal areas, starting large fires. As the B-25s left the target to return to Makin they were chased by about 15 Japanese fighters. 30 miles south of Maloelap the 12 P-40s met the bomber formation and immediately engaged the enemy fighters, destroying11 of them and severely damaging 2 more. The strike of January 26 was decisive. Practically all of the remaining enemy air strength at Maloelap had been destroyed, and the once formidable base was rendered almost powerless to defend itself against air strikes,  thus neutralized. Jaluit was subjected to 15 attacks reduced to rubble and Wotje was hit 14 times suffering extensive damage.

Meanwhile Admiral Pownalls task force 58.1 and 58.3 consisting of 6 fast carriers, 5 heavy cruisers, 2 light cruisers, 3 of the new class of anti aircraft cruisers, and 12 destroyers hit Kwajalein on December 5th. That day saw her attacked by over 246 aircraft. As a result 19 Japanese interceptors and 4 bombers were destroyed at Roi-Namur, 7 cargo ships were destroyed at Kwajalein and extensive damage was inflicted upon both bases. Simultaneously, 29 aircraft hit Wotje where they destroyed 5 grounded aircraft, set fire to hangers, machine ships and barracks. Japanese interceptors attacked Pownall’s carriers, though they were unable to inflict serious damage. Following these attacks, Hoover’s aircraft continued to smash Kwajalein, tossing 10 attacks, dropping nearly 210 tons of bombs on the atoll. Roi-Namurs airfield still remained operation by January 29th however, though she only had 35 aircraft on Roi-Namur; 10 reconnaissance planes on Kwajalein; 13 aircraft on Maloelap; 12 on Wotje and 15 on Eniwetok. The Japanese did not have any effective air force to defend the Marshalls any more. The feeling of the men on the islands, was doom.

Finally the Australians had taken the formidable position known as Shaggy Ridge. The Japanese continued the harrowing marches going north as their enemy would not let up. In the Marshalls the IJA and IJN personnel were inflicted the full might of American’s wartime productivity, and they all knew Uncle Sam was coming to pay them a visit soon. 

- 113 - Pacific War - The Battle for Shaggy Ridge , January 16-23, 1944

Last time we spoke about the landing at Saidor and continuation of advances upon New Guinea and New Britain. Operation Michaelmas was a huge success, isolating countless Japanese and threatening those trying to retreat further north. Taking advantage of the new front on New Guinea, the Australians began pushing more so upon the features across Shaggy Ridge and towards Sio. General Adachi frantically shifted units around in an effort to plug up the multiple advancing allied units, but in the end there was little to be done as the Japanese were pushed further and further north. Features were taken upon Shaggy Ridge and Sio fell nearly uncontested. Over in New Britain, General Rupertus triumphed over the Airdrome and his Marines were expanding their perimeters. Katayama made a bold attack against an enemy he overestimated at it certainly did not pan out for his men at suicide creek.

A while back I covered the start of the Chinese-Indian offensive into the Hukawng Valley and Arakan regions. When I did so it was almost entirely from the allied viewpoint, but what of the IJA war planners? The Burma campaign has been arguably a complete disaster for the allies, the Japanese steamrolled all the way through, claiming vast amounts of territory and key cities and ports, so what really did they need to do but garrison it all? After Wingate unleashed operation Longcloth, the relatively idle Japanese raised the idea of potentially attacking India. Lt General Mutaguchi Renya, the victor of the Singapore campaign in 1942 was made a commander in Burma and wargamed the possibility of attacking India to try and earn support from his superiors at Tokyo General HQ. It was his belief, they could brush past the British in Assam and reach the gateway into India, and he expected the Indians to rise up and greet them with open arms. A lot of money and effort had been spent on Subhas Chandra Bose and his Indian National Army. The fall of India would be an absolutely devastating blow to the British Empire in Asia and in 1942 there was even the belief the Japanese could link up with their German allies in the middle east. But that was 1942, before Stalingrad and Kursk, 1944 was a very very different geopolitical situation. This however did not stop Mutaguchi from continuing his plans to invade India. Lt General Hanaya Tadashi, commanding the Arakan front was given the task of convincing the British that the counterattack in Arakan was the appearance of the main army earmarked to conquer India, thus leading General Slim to send up reserves from Imphal. The operation was codenamed HA-GO and it was intended to be a fent to mask the real attack upon Imphal designated Operation U-GO. Now let me dig a bit deeper into how this all came about.

Until now, General Stilwell had been able to build much of the Ledo Road practically unmolested. Yet by early August, General Kawabe Mazakazu’s Burma Area Army was preparing for a counter offensive. Kawabe actually did not trust Mutaguchi and suspected the man was harboring megalomaniac designs to invade India, which he was 100% right about. The “counter offensive” was really just the beginnings of Operation U-GO and it had been sold to Tokyo HQ as a pre-emptive strike to disable the 14th Army and make it unable to invade Burma. Thus General Mutaguchi’s 15th Army was given the task of destroying any hostile elements in the Imphal region and to establish a strong defensive line. From December 22nd to the 26th, Mutaguchi held a conference pushing for the possibility of launching Operation U-GO and developed detailed missions for each division which would participate by means of a war game. At the same time Kawabe sold the operation HA-GO the diversionary attack in Arakan, with Lt General Hanaya Tadashi’s 55th Division earmarked to pin down as many of the enemy’s units as possible and to draw the British reserves away from the main offensive. 

When General Christisons offensive kicked off, this forced Kawabe to reinforce Hanaya with the 54th division, and this in turn established the 29th Army under the command of General Sakurai on January 6th. The 29th Army was under the overall command of the Burma Area Army, and its HQ was initially situated in Moulmein. It was assigned to defend the coastal region of Arakan and the lower Irrawaddy valley and consisted at first of the 55th Division in Arakan, the 54th Division in reserve in Prome, and various garrison units including the 24th Independent Mixed Brigade in Moulmein. It also controlled the 11th Shipping Detachment of Major-General Suzuki Gisaburo, consisting of the 11th Shipping Engineer Regiment and the 3rd Sea Transport Battalion. It had roughly 1,105 men, 85 large landing barges, 54 small landing barges, 47 motored sampans, two armored boats, 10 fishing boats, one messenger boat and one speed boat. The 11th Shipping Detachment was stationed at Taungup and its main supply depot was at Prome.

Meanwhile after the capture of Maungdaw, the 5th Indian division of Major General Harold Briggs was ordered to attack the main Japanese defenses at Razabil. Razabil’s defenses were quite formidable, it dominating the crossroads and road linking Maungdaw with the Tunnels and Buthidaung located 3 miles eastwards, forming the 15th Indian Corps immediate objective following Maungdaw's capture. It was dubbed by its Japanese commander “The Golden Fortress of the Mayu Range”. It was centered on the railway tunnels running through the Mayu Range and at Point 551 to the east with a further forward position at Point 1301. These powerful defenses, built carefully exploiting the rugged mountainous terrain, were tunneled deep into the hills and consisted of bunkers, trenches and other fire positions located amidst dense jungle and camouflaged with customary Japanese skill. The main outworks at Letwedet to the east and at Razabil to the west of the Mayu Range were major fortresses in their own right, requiring careful reduction before the main position could be tackled. With both bastions in direct line of sight from the Tunnels, accurate supporting artillery could be called down with ease, moreover, adding to the problems already facing troops assaulting trenches and bunkers dug into the hillsides invulnerable to all but direct hits by medium artillery.

The offensive against Razabil was codenamed Operation Jonathan, but it would be delayed until the corps artillery became available. At the same time the 7th Indian division seized the initiative on January 18th and launched an attack against the 55th division’s position between Letwedet and Htindaw. The 9th company, 143rd infantry regiment was defending a hill east of Htindaw and stood their ground against repeated attacks until January 24th. The Japanese strongpoints were well dug in on the tops of narrow ridges. On January 26th, Major General Briggs ordered the 161st brigade, with support in the form of Lee-Grant tanks, artillery and aerial bombardment to attack the Tortoise defended by 1st battalion, 143rd regiment in the Razabil area. The Tortoise was a horseshoe defensive position that dominated the highway. It was an elaborate system of bunkers, trenches and all the typical Japanese goodies. For the boys in Burma it would be the first time for most to face such a thing, as Slim wrote in his memories “This was the first time we had assaulted an elaborate, carefully prepared position that the Japanese meant to hold to the last."  

The attack opened up with 12 Vultee Vengeance dive bombers of the 3rd Tactical air force, 12 Mitchell medium bombers and 16 Liberator heavy bombers of the Strategic air force followed up by even more dive bombers. It was a visually spectacular event and to those observing from the ground looked devastating. However little to no damage was inflicted on the strongly constructed Japanese defenses burrowed so deeply into the hillsides. Similarly the mountain artillery regiment and batter from a field regiment did little damage with their bombardment as well. The Japanese had simply pulled back 1000 yards during the bombardments and by the time the allies surged forward came back to man their positions. When the Indians began their assault, the fire coming down the steep and jungle clad hillsides was absolutely devastating. The Lee-Grant tanks fired from the valley floor and managed to destroy all the identified bunkers, but the exposed Indian troops suffered massive casualties. It was virtually impossible to keep the defenders heads down long enough to advance even 50 yards towards the summit. Things got even worse when the men reached the defensive lines for the Lee-Grant tanks had to lift their fire lest they hit their own men. By the end of the day, only a toehold had been secured over the lower slopes of Razabil ridge. 

The assault carried on for 3 more days, with intense tank and artillery fire from different directions supporting the infantry as closely as possible. The only immediate effect of the bombardment and indirect fire by 25 pounders and 3.7 howitzers was to destroy the vegetation over the hillsides, thus exposing more and more of the Japanese defensive works. During the intense battle, the Lee-Grant medium tank proved itself a real solution in providing effective covering fire for infantry and soon new techniques were evolving. The Japanese defenses were mainly built over the summit of steep, thick, jungle covered hills and the Lee-Grants provided fire support from positions in the paddy fields below them. Their 75mm guns effectively destroyed or at the least neutralized bunker positions. A procedure was quickly developed for providing cover during the last stages of infantry assaults. Tanks would use high explosive shells to clear the vegetation, than delayed action high explosive shells to break up the front of visible bunkers, then armor piercing shells to enable the infantry to advance close behind the creeping barrage as shrapnel was not flying everywhere. All combined this showed the potential of armor vehicles in jungle warfare, when most claimed they had little practical use in such climats. Despite such developments, the casualties were mounting, little progress was being made.

On January 28th, the 123rd brigade attacked Japanese positions on the secondary hill of Wrencat and its smaller neighbor hill Wrenkitten, probably the best hill names I have read on this podcast as of yet haha. These were located on the lower western foothills of the Mayu range. They were extremely steep, cone shaped features with fortified circular trenches around their heads, bunkers, and bamboo jungle. Firing from positions on the valley floor the Lee-Grants and 5.5 inch artillery were able to destroy the bunkers and switch to armor piercing rounds to perform creeping barrages for the infantry. Despite the tank and artillery support, the Japanese were throwing a ton of mortar, grenade and machine gun fire. An officer of the 123rd brigade involved in the fight had this to say 'It appears from our experience that consolidation on the objective which normally consists of a series of deeply constructed bunkers connected one with the other is extremely difficult in the very limited time that the enemy allow.' The failures against the Tortoise and Wrencat, prompted General Christison to call off the attack against Razabil by January30th. Christison regrouped his corps artillery and tanks to instead support the 7th divisions assault against Buthidaung and Letwedet.

 

Meanwhile further to the north, General Tanaka had brought 6300 men of the 55th and 56th regiments to the Hukawng valley by early January. He wanted to counterattack in strength, but General Mutaguchi believed he could not spare additional motor transport units to give the necessary logistical support to the 18th division since preparations were already going on for operation U-GO. Thus, Tanaka ordered his men to perform a delaying action down the Hukawng valley with the primary objective of holding Kamaing, the ridge line separating Hukawng valley from Mogaung valley. Tanaka weighed his orders and the looming monsoon season that hit the area in May or June. Against Tanaka, Stilwell sought to continue his offensive after successfully taking Yupbang Ga. Stilwell now looked towards Taihpa Ga and convinced both General Wingate and Admiral Mountbatten to unleash the Galahad long penetration unit into the Hukawng valley.

 

On January 4, 1944, Frank Merrill abruptly relieved a disappointed Brink. Despite having a background with cavalry, like Brink, Merrill understood the Japanese strength, but unlike Brink he respected the chain of command. General Sun met with Stilwell and and it was agreed the bulk of the 114th regiment should swing widely around Tanaka’s left flank while the 113th regiment wheeled to the south to hit Tanaka’s front along the Tanai Hka. Further north the 2nd battalion ,112th regiment would also advance east across the Tarung Hka to secure Warang Ga; the 65th regiment would continue their advance towards Taro, fording the Tanai river by January 9th; south of Kantau, the 3rd battalion, 114th regiment ran into two Japanese companies. The jungle made it difficult for the Chinese forces to organize themselves. The battalion split into 4 fragments and no two of them were in contact. The supporting 6th battery could not fire until fields of fire were cut and while that was being carried out, the Japanese companies performed infiltration maneuvers and quickly surrounded the battery. Fighting for their guns and lives between the 9th and 11th of January the Chinese cannoneers managed to save both. The battalion was nearly wiped out from these Japanese tactics, but thankfully on January 12th, the regimental HQ arrived and reformed the battalion to launch a concerted attack that managed to gradually push back the Japanese. 3 days later the 2nd battalion arrived allowing the 114th regiment to force a crossing of the Sanip Hka by January 16th.

 

Meanwhile the 1st battalion, 113th regiment forded the Tarung river near Yupbang Ga and sent patrols north to occupy Tabawng GA on January 13th. From there they advanced southeast to Kaduja Ga then to Brangbram Hka where they formed a line extending to the junction with the Tanai bank by mid january. On January 21st, the Chinese broke through the Japanese lines north of Brangbram Hka and made it to Ningru Ha less than one mile downstream from Taihpa Ga. Simultaneously, the battered 112th regiment swung wide going north east to Warang Ga. By the end of January the 113th continued their advance upon Taihpa Ga where they would meet stronger Japanese resistance. They began fighting within 1,500 yards of Taihpa Ga. Artillery support, the 4th and 5th Batteries, was then brought up. The next 1,000 yards between the 113th regiment and Taihpa Ga took two days to cross; then they spent a week in what was called "preparations for attack." General Sun's men were now approaching the Japanese strongpoint in the area, and Japanese resistance was more freely offered, with heavy shelling by 75- and 150-mm. pieces. At Taihpa Ga, the Kamaing Road crossed the Tanai on a long gravel bar which bullock carts could use quite well. At this point was the village itself, a humble collection of bashas, long since burnt out. About 800 yards upstream was a ferry across a stretch of fairly deep water. The Japanese used this ferry to bring supplies across the Tanai, rather than the vulnerable and easily spotted gravel bar. Here they had their strongpoint, well prepared and stubbornly defended.

 

Further to the west, the 65th regiment advance was much slower than expected for Stilwell.  Upon reaching the Hukawng Valley, the 65th's commander, despite means more than ample for his mission, contracted the same lethargy that had hastened the demise of the 112th Regiment. Stilwell was greatly frustrated by the delay a few more weeks with Colonel Fu, so he ordered Colonel Liao to relieve him. Stilwell wrote in his diary "Told Liao this included division commanders unless they watched their step. Also that Fu really should be shot. Liao took it OK though it shook him up." On January 22, General Sun was told about this affair, but the news softened somewhat by the presentation of a silk banner for the victory at Yupbang Ga, a dramatic contrast of the respective awards for lethargy and vigor. Having made his point, and hoping that he had given the Chinese a healthy shock, Stilwell restored Fu to his command by January 26. Fu's later performance in combat was rated as excellent.

 

The Chinese managed to encircle the passive 3rd battalion, 55th regiment on January 23rd, and by the 25th the last Japanese pockets were wiped out. On the 26th the Chinese reached Ahawk Hka and on the 28th crossed the Taro river and occupied Taro on the 30th. This effectively cut behind Tanaka’s flank. The bulk of the 112th now was close enough to the 113th to aid them so Sun began an attack against Taihpa Ga on the 30th. The Japanese held on stubbornly for days and would quietly withdrew on the night of February 4th. Tanaka concluded the loss of the Taro plain meant "the failure of the whole division in its operations along the Tanai". Thus Tanaka decided there was no point in continuing the fighting there. Over at Sanip, Sun ordered the 3rd battalion, 114th regiment to rest. However Stilwell thought this was close to disobedience of his orders,  because he wanted Sun to move quickly and cut behind the 18th Division. On January 13, he had spoken very bluntly to Sun, asking him what orders he gave the 114th Regiment and if there had been any word from Chongqing to slow the operation. Stilwell told Sun that if he could not exercise the commands that Peanut had given him, he would resign and report the whole affair to the US Government. "Regardless of what anyone else may say, I assure you that my report will be fully believed in Washington." General Sun was confronted with the prospect that Chinese lethargy in north Burma might mean withdrawal of all US help from China. Stilwell, Sun was told, had been alone in his fight to convince the United States that the Chinese Army was worth helping. "If I am double-crossed by the people I am trying to help I am through for good and I will recommend very radical measures." Stilwell closed by saying that he had done his part; would Sun reciprocate? But despite Stilwell's arguments and threats, General Sun did not meet Stilwell's ideas of how a dynamic field commander should conduct himself.

Thus the 114th gradually began to dislodge the Japanese from their positions along the river bank, taking care to annihilate all pockets behind. Stilwell was satisfied with the progress of his offensive and established the northern combat area command on February 1st. This organization would be led by Brigadier General Haydon Boatner and would include American, British and Indian units entering North Burma. But that is all for the wild Burma front as we now need to travel over to New Guinea.

 

Last time we were in New Guinea, Brigadier Chilton’s 18th brigade had just completed their advance upon Shaggy Ridge and Brigadier Hammer’s 15th brigade had just relieved the 25th brigade on January 7th. Thus two brigades were flown in and two were flown out, showcasing how far the allied New Guinea air forces had increased their efficiency during the war. The New Guinea force was now under the command of General Milford, though Vasey still retained his task of  "contain hostile forces in the Bogadjim-Ramu area by vigorous action of fighting patrols against enemy posts”. The division's role was still to prevent enemy penetration into the Ramu-Markham valley from Madang and protect the Gusap airfield and the various radar installations the instruction added that the division would "create the impression of offensive operations against Bogadjim Road by vigorous local minor offensive action". This was to be done by holding in strength with two brigades a "line of localities" from Toms' Post on the right to the Mene River on the left, the boundary between the 18th on the right and the 15th on the left being a line from Bebei through Herald Hill to Kankirei Saddle. In addition the 18th Brigade would "by raids and harassing tactics ensure that no major Jap withdrawal takes place undetected and occupy the Mindjim-Faria divide and the high ground to the north and south of it as the administrative position permits". The 15th Brigade would hold the Yogia-Mene River area, delay any enemy advance up the Ramu from the Evapia River, patrol to the Solu River, and deny the 5800 and 5500 Features to the enemy. 

 

Despite this, Vasey was preparing to assault the Kankirei saddle with the fresh 18th brigade. Designated Operation Cutthroat, the seizure of the Kankieri saddle and ultimately that of Shaggy Ridge, Vasey planned to launch an attack against Mount Prothero which was being defended by the 6th company, 78th regiment. He would attack it from the south, preceded by a diversionary attack against Cam’s saddle. Brigadier Chilton realized however, that frontal attacks along Shaggy Ridge would not be able to achieve surprise, so he instead wanted to attempt a wide encircling maneuver on the left flank via Canning’s saddle to attack Prothero directly. The 18th brigade spent the early part of January patrolling to see if it was possible to advance through Canning’s saddle to Prothero 1 while simultaneously and stealthily building a road to Canning’s in preparation for the coming offensive.

 

The possibility of occupying Prothero from Canning's Saddle had been suggested to Chilton by Lt-Colonel Lang of the 2/2nd Pioneers, after a patrol performed by Captain McInnes. Captain McInnes had found an approach along a steep, razor backed spur within a short distance of Prothero’s summit where they could hear Japanese. Meanwhile the 2/9th battalion had sent a patrol that found a possible track from McGullough’s ridge vie Geyton’s Hill to the Mene River. Going up the river bed led one to Canning’s saddle. Two companies of the 2/12th spent a few days constructing a track going to the Mene River and they took special precautions to prevent the enemy from finding out. Reconnaissance patrols in general were careful to avoid contact with the enemy and so was the case around Prothero. The jeep track was hurriedly pushed to Guy's Post, existing tracks were improved and shorter and better tracks constructed to improve the supply routes to Shaggy Ridge and Mainstream; reserves of supplies in forward areas were built up, thus enabling a concentration of as many natives as possible to carry for the attacking battalion on the left, and arrangements were made for a limited air dropping at Canning's Saddle at an appropriate time.

 

To support the upcoming attack, 9 long and two short 25 pounders of the 2/4th field regiment were brought up along with 7000 shells. The guns had to be dragged forward to the Lakes-Guy’s Post area. Lt Colonel Charles Bourne’s 2/12th battalion was to head the attack. Chilton also planned to have Lt Colonel Charles Geard’s 2/10th battalion perform a diversionary attack through Cam’s saddle. After Protharo 1 was captured, the 2/10th were to exploit north to Kankieri and south to the Mainstream area; while Lt Colonel Clement Cummins 2/9th battalion attacked northwest along Shaggy Ridge to join up with the 2/12th. By January 18th, the 4000 yard track to Geyton’s Hill was complete, allowing the 18th brigade to advance. On that same day, B-25 Mitchell bombers unleashed their cannons and bombed the enemy positions at the junction of Mainstream, the Faria and Shaggy ridge. They dropped 60 delayed action bombs over the Faria river valley and some modified Mitchells sporting 75mm cannons mounted on their chins fired upon the crest of ridges. This cannon, the same used by Sherman tanks, was quite a formidable weapon in the air. To enable its fire, the nose of the B-25G model had to be shortened and the cannon breech positioned behind the pilot from where it could be loaded by the navigator for firing. To fire it the pilot would press a button on his control wheel. The weapon would prove inefficient against shipping, but it would be a lot more successful at hitting ground targets. Over three successive days from 18 to 20 January the Mitchells flew 180 sorties against Shaggy Ridge, firing 135 rounds of 75 mm at the ridge as well as dropping around 200 tons of bombs. The aircraft also fired about 90,000 rounds of .50 caliber. The machine-gun salvos were particularly devastating. From his accompanying Boomerang, Alex Miller-Randle recalled ‘Mitchells strip the trees of Shaggy Ridge clean and shatter the limbs and trunks to matchsticks’.

 

D-day was the 20th, seeing the 2/10th on the right and 2/12th on the left. Captain Kumnicks company of the 2/10th advanced to Grassy Patch and over on the left a party of the 2/12th led by Major Fraser took vanguard. All of the preliminary actions were completed back on the 19th when Captain Gunn’s A company of the 2/10th advanced from Tom’s Post for Sprogg’s ridge via a Japanese mule track. Later Captain Humnicks D company would use the same track. On the left the 2/12th battalion and B and D company of the 2/2nd Pioneers advanced along the new line of communication to Geyton’s. At 8:45am Captain Gunn’s company advanced from Sprogg’s ridge to attack Cam’s Saddle, followed 30 minutes later by Captain Kumnick’s company. Operation Cutthroat opened up with artillery and B-25 mitchell bombardments against the Protheros and Kankirei Saddle. By 11 a .m. Captain Gunn was 300 yards from an enemy position on Cam's Saddle while artillery shelled the position until 12.30 pm when the Australians found that the enemy had withdrawn.

 

Farther on, Captain Gunn’s men would be pinned down by Japanese defending the western end of the saddle as Japanese patrols ambushed a signal line party 500 yards behind. Gunn initially tried to outflank the enemy, but then withdrew 200 yards and dug in for the night astride the mule track. At the same time, the 2/12th battalion reached Canning’s Saddle by 3:30pm. The next morning, the 2/12th began to silently creep along the razor back ridge towards Prothero 1 with Cameron’s C Company taking the lead. At this point Fraser had Captain Cameron’s C Company, Captain Geason’s A Company  and Captain Thomas’s D company enveloping the ridge. They nearly achieved surprise, but the Japanese discovered their advance and rapidly turned their mountain gun upon them causing many casualties. Despite the mountain guns fire, Lt Braithwaites 8th Platoon charged the Japanese and captured the mountain gun upon Prothero 1. The action cost 11 Australian lives with another 44 wounded. The 2/12th had thus captured the key point in the Japanese defenses upon Shaggy Ridge. After the loss of the mountain gun position, Colonel Matsumoto ordered his men to pull back closer to Kankirei. In the process the 2/10th were able to capture Cam’s Saddle. On that same day the 2/9th began their attack, sending A Company to envelope the Green Sniper’s Pimple defended by a platoon of the 78th regiment. A Company managed to seize the position using stealth and would be met by failed counterattacks. By the end of the day the Japanese defenders were now sandwiched between the 2/9th to the south and the 2/12th to the north, while the 2/10th were advancing from the east.

 

Way further to the east, General Nakano’s men were in an even more dire situation. After the evacuation of Sio, the Japanese were forced to retreat day and night under heavy rainfall, hindered by rough terrain and allied aerial attacks. Lieutenant General Yoshihara Kane, Chief of Staff of the 18th Army, recalled this of the march: “The most wearing part was that with these ranges, when they climbed to the craggy summit they had to descend and then climb again, and the mountains seemed to continue indefinitely, until they were at the extreme of exhaustion. Especially when they trod the frost of Nokobo Peak they were overwhelmed by cold and hunger. At times they had to make ropes out of vines and rattan and adopt "rock-climbing" methods; or they crawled and slipped on the steep slopes; or on the waterless mountain roads they cut moss in their potatoes and steamed them. In this manner, for three months, looking down at the enemy beneath their feet, they continued their move. Another thing which made the journey difficult was the valley streams, which were not usually very dangerous. At times, however, there was a violent squall, for which the Finisterres are famous during the rainy season; then these valley streams for the time being flowed swiftly and became cataracts. Then there were many people drowned... General Shoge was swept away by one of these streams on one occasion but fortunately managed to grasp the branch of a tree which was near the bank and was able to save one of his nine lives.”

 

The men were malnourished, fatigued, but kept going day by day anticipating an abundant food supply at Gali. When they reached Gali in late January they would find nothing there. This anguish was just the beginning. The base had been shelled by allied warships and bombed by allied aircraft. General Muroya was injured on January 17th during the bombardment. Luckily for the Japanese there was no offensive towards Gali. Since the Saidor landing, General Martin’s men were busy expanding the perimeter with outposts extending towards Sel and Bilau. Martin was reinforced with the 1st and 3rd battalions of the 128th regiment on January 16th. Although Martin believed launching an eastern attack upon the withdrawing enemy would provide an excellent opportunity to destroy some of their divisions, General Kreuger refused to permit such a thing. This was because the 32nd division was required for an upcoming offensive in the Hansa Bay area.

 

Meanwhile General Nakai had brought the bulk of his detachment over to the Mot River area and established a strong outpost on Gabumi. Nakai also sent the 3rd battalion 239th regiment to Bilau to try and contest the control of its outpost. On January 12, the Japanese attacked Biliau, forcing the Americans to retreat behind the river. 30 Americans then tried to retake the outpost the following day but were repelled by the Japanese. On January 15th, the Japanese withdrew, allowing the 1st Battalion, 128th Regiment to occupy it on January 20. Another Japanese attack on January 26 would force them to retreat; and two days later, the Americans were successfully ambushed when they tried to reoccupy the outpost. Nakano’s men had thus successfully carried out a fighting withdrawal from Lae. They had suffered horribly for it, crossing unbelievable difficult terrain, with basically no supplies, apart from what meager amounts could be airdropped or brought over via submarine. Yet now they needed to break through towards Madang, and there were 3 possible options of doing so. Number 1, they could advance along the coast, but this one was disregarded immediately because they would have to break directly through the new American defenses. Number 2, codenamed A would be an advance inland through Cabutamon, Monara, Sibog and Bilau towards Mindiri. Option 3 codenamed B was an advance even further inland crossing over the foothills of the Finisterre, through Nokopo, Kwembum, Yugayuga, Gabumi and Singor towards Mindiri. Nakano elected to send the 20th division over plan A while his division would advance in 3 echelons over plan B.

 

On January 23rd, the 51st division departed Gali along the B route while the 1st battalion, 115th regiment and General Katagiri’s 20th division would advance along the A route. Katagiri’s 80th regiment and 20th engineer regiment tried the best they could, but the march was only advancing a single kilometer per day. Katagiri’s troops had to cut through dense jungle and were facing strong enemy patrols along their route. Facing greater difficulties than expected, Katagiri decided to follow Nakano’s 51st division along the A route in the end. Yet unbeknownst to him, the 3rd battalion, 126th regiment had just established new outposts at Sibog and Paramusi on January 22nd. From there they were sending out patrols to Langani and Sindaman. The Americans still could not break through Nakai’s defenses at Gabumi giving the Japanese some relief. The bulk of Nakano’s forces were withdrawing smoothly, seeing just sporadic harassment from American patrols. On the 1st of February, the 1st battalion, 115th regiment finally made contact with Nakai’s forces at Gabumi while the bulk of the 51st division advanced through Yugayuga. A week later, Nakano himself reached Gabumi and began advancing towards Madang. By the 16th of February, the 1st battalion, 115th regiment reached Madang and the 20th division had successfully pulled out of Gabumi.

 

Late February would see 1667 men in total arrive at Madang, 5469 would reach Singor and 1235 would reach Gabumi. Thus 80% of Nakano’s strength had effectively withdrawn. Nakai also managed to collect 500 patients that had been abandoned at Yugayuga and brought them over to Madang by March 1st. It seemed once again, Nakano’s men had escaped doom. On the other side, Brigadier Cameron had begun his advance towards Saidor on January 25th. His 4th battalion led by Lt Colonel Percy Crosky, with a Papuan company reached Kiari on January 28th. Without taking a break they continued towards Singor the next day, then Malasanga and Crossingtown by the 31st.

The Japanese were slowly but surely losing their hold over Shaggy Ridge. With the loss of the vital artillery position it was just a matter of time before the Australians took over the area, meanwhile Nakano’s great retreat was a success, but one does not win a war moving backwards. 

- 112 - Pacific War - Ledo Road Offensive , January 9-16, 1944

Last time we spoke about the landing at Saidor and the drive against Sio. The Australians were still advancing across Shaggy Ridge when General MacArthur unleashed an amphibious assault against Saidor to cut off the Japanese escape and isolate Sio. Numerous features were seized up the large ridge and the Americans successfully amphibiously assaulted Saidor and seized their airfield. General Adachi placed the 51st and 20th divisions under the command of General Nakano, who was tasked with advancing to Gali to try and secure a new supply point. Meanwhile efforts were made to try and contain the new threat in Saidor while simultaneously holding back the Australians in the south. Over on new britain the airdrome was seized as Colonel Katayama launched a failed counter attack against the Marines. The Marines tossed back the attack and began their own advance further inland.

The Americans had landed at Cape Gloucester, Saidor and were carrying out massive attacks against Rabaul. As we had seen previously, on November 5th, aided by bad weather, a surprise air raid was made by the USS Saratoga and Princeton, led by Rear-Admiral Frederick Sherman that inflicted heavy damage to 4 cruisers within the harbor; Maya’s engine room was smashed by a bomb killing over 70 men; a 500 lb bomb hit Mogami; Takao took 2 500 lb bomb hits while 3 500 lb bombs narrowly missed Atago killing 23 seamen and caused severe damage to the ship’s plating. 2 other cruisers and 3 destroyers also suffered light damage. Captain George Chandler flying a P-38 fighter pilot described how “There were B-24 bombers up high and B-25 bombers attacking right down on the deck dropping ‘frag’ bombs on the airplanes along the runways … we did our best work at high altitude, but we also took part in combat a thousand feet off the ground.”

The devastation caused Admiral Miniechi Koga to withdraw his forces to Truk, thus ending the IJN threat to Bougainville. A Japanese naval officer would later admit that they had given up on Bougainville mainly because of “the serious damage received by several Second Fleet cruisers at Rabaul by carrier attack …” The successful  raid against Rabaul left Halsey ecstatic. “It is real music to me and opens the stops for a funeral dirge for Tojo’s Rabaul.” On November 8th, reinforcements led by Rear-admiral Alfred Montgomery task force 38, with the new fleet carriers USS Bunker Hill, Essex and Independence. With the added carrier strength on November 11th, a follow up air raid was made seeing the IJN cruiser Agano torpedoed and badly damaged, while 35 Japanese aircraft out of 120 launched in a counter attack against the carrier force were shot down. Montgomery would not lose a single ship. Admiral Koga’s decision to send carrier pilots to bolster Rabaul had quite literally blown up in his face. Koga’s air fleet had lost 43 of its 82 Zeros, 38 of its 34 Vals, 34 of its 40 Kates and 6 Judy spotter planes. Over 86 of his 192 experienced pilots and crew had perished, and he had only inflicted minimal damage to Nimitz fleet, it was a disaster. Yet the fantastical reports from Japanese pilots kept pouring in, claiming the air battles over Bougainville were infact won by the IJN air forces. Newspapers in Japan reported victories that added up to the destruction of 5 American battleships, 10 carriers, 19 cruisers and 7 destroyers. The reality was the destruction of 2 cruisers, the USS Birmingham and Denver.

By mid november Vice Admiral Kusaka was finding it difficult to sustain attacks against allied convoys feeding supplies to Empress Augusta Bay. On November 12th, Rabaul only had 113 Zero’s of which only 59 were operational. Crews were suffering from malaria and other diseases, no one was granted rest as they were limited in personnel and under constant attack. The quality of ground crews and pilots was deteriorating every week. 

From November 12 through December 16, the daytime skies over the Gazelle Peninsula remained relatively quiet, as the US carrier forces had departed to support operations in the Central Pacific. AirSols received a new commander on the November 20th, Major General Ralph Mitchell who continued to support operations in Bougainville and General Kenney’s Fifth Air Force was supporting preparations for the landings in western New Britain. The lull gave Admiral Kusaka a brief opportunity to recuperate as replacements began to arrive from the Marshalls and Truk. The Imperial Japanese Navy would take six months to replenish its carrier pilots with less well-trained and inexperienced replacements. In the meantime the carrier fleet itself, Japan’s most expensive and precious strategic asset, was forced to remain idle in Truk as Nimitz began his island hop through the Central Pacific

Meanwhile the Torokina airfield had become crude but operational. The Seabees had created a single 4750 foot by 200 foot strip. It lacked taxiways, hardstands and buildings, but by December 10th it could launch aircraft. Soon the Seabees would carve 2 additional landing trips in the jungle 3 miles further inland. The first would be a mile long, the second 8000 feet or so for bombers. Unlike the Japanese airfields on the Gazelle Peninsula which would take more than a year to complete, both of these American airfields took a month. You often hear, especially from marine veterans of the pacific, praise for the Seabees, such a colossal advantage in logistics paved the way to victory.

A massive fighter sweep was launched on December 17 consisting of 32 Corsairs, 24 F6Fs, and 24 RNZAF Kittyhawks from airfields at New Georgia and Vella Lavella who rendezvoused at Torokina, topped off their fuel tanks, and hit  Rabaul. The strike was led by Major Greg “Pappy” Boyington, the commanding officer of Marine Fighter Squadron 214, better known by its nickname, the "Black Sheep Squadron". The three types of aircraft had different flying characteristics and different cruising speeds. The Kittyhawks, slowest of the bunch, took off first. The plan was for them to come in at 15,000ft, and lure out the Japanese. Next came the Hellcats, flying above the Kittyhawks. And the last were the Corsairs, who flew top cover. It was a long flight over open water, calculated to make the pilot of a single-engine aircraft nervous. If the engine failed it was a long swim home. They were intercepted by 35 Zeros, with the Kittyhawks getting the first jump on them. After the Kittyhawks made their first pass, shooting down a Japanese fighter, the advantage switched over to the more agile  Zeros. The Kittyhawk squadron leader’s plane was fatally damaged and a second Kittyhawk went down after colliding with a Zero. Remarkably, both pilots survived. Meanwhile the Hellcats and Corsairs, at high altitudes, were coming up empty. The Corsairs circled Lakunai field finding no targets. Pilot Boyington exchanged insults with an English-speaking Japanese officer over the radio, but despite his challenges found no targets in the air. When all aircraft returned to base, the score was even. Two Kittyhawks and two Zeros were lost; one each due to the collision and one shot down by both sides.

It was a rather disappointing fighter sweep, but would become just one of many against Rabual over the course of the next 3 weeks. The next raid came two days later seeing 48 B-24s launched, but 32 were forced turned back. The remaining 16 bombers escorted by 51 were intercepted by 94 Japanese fighters, yet they also suffered from the bad weather. Less than half made contact with the enemy. In the resulting fight, 5 Zeros were shot down and 10 allied aircraft were lost, but only two were shot down. The other eight were due to a mid-air collision and landing mishaps, all near home. The weather persisted to be so bad, it was only on the 23rd another sortie could be launched. B-24s escorted by Corsairs and Hellcats bombed Lakunai. Radar gave the Japanese some early warning and nearly 100 Zeros were scrambled. 60 made contact with the bombers after they hit Lakunai. No bombers were lost, but 2 Corsairs were shot down in the ensuing dogfights. Yet the Americans had a twist, they followed up the raid with a fighter sweep of 48 Corsairs. They arrived 15 minutes after the bombers left, surprising the airborne Japanese fighters, most of whom lacked radios. 6 Zeros were shot down, several others damaged and only 2 Corsairs lost. 

2 days later, another fighter sweep preceded by bombers was launched claiming 18 aircraft kills, but it was probably closer to 5. In comparison the Japanese pilots would claim 55 kills, a number greater than the american force sent. On the 27 another sweep was launched against Cape Gloucester downing 7 Japanese aircraft for one American. 28 Corsairs returned the next day but this time the Japanese held the advantage, sandwiching the Marines between 2 large groups of Zeros. 3 Corsairs were shot down, but so were 3 Zeros, with 2 others badly damaged. On 30th 36 Liberators escorted by 20 Hellcats and 20 Corsairs, bombed Rabaul. 1 B-24 was lost on the raid, hit by antiaircraft fire. No air combat occurred. On New Years day 15 B-24s and 68 escorting fighters met heavy fighter opposition. 40 Zeros had been sent to Rabaul from Truk, manned by veteran pilots. 1 B-24 was shot down, and two others badly damaged. On January 2 48 US fighters raided and on the 3rd another 44. The two sweeps took out a handful of fighters. The last sweep was on the 5th seeing another 2 zeros downed.

Meanwhile back on December 24th, Admiral Sherman’s task force 37 raided Kavieng. The operation had two purposes, 1) was to distract attention from the landings at Cape Gloucester and 2) to interdict sea traffic between Truk and Rabaul. The 5000-ton naval transport Tenyru Maru was sunk and several other ships were damaged. After this task force 37 made several raids against Kavieng through January 4th. They managed to shoot down 10 Japanese fighters, damaged IJN cruiser Noshiro and destroyers Fumizuki and Satsuki. On Janaury 6th, the bomber strip at Piva became operational, thus Rabaul was now within range of allied light and medium bombers, basically it was pounding time.

 

On January 7th, 16 Avengers and 24 Dauntless raided Tobera airfield. From medium altitudes the Avengers dropped 2000lb pounds smashing the paved runways. The Japanese managed to shoot down 3 fighters and one dauntless, but Tobera was temporarily not operational. It was the first time any Rabaul airbase was neutralized from bomb damage. This would be followed up on the 11th by a low level attack against Vunakanau by B-25’s, damaging 8 parked aircraft. Then on the 14th, Simpson Harbor was attacked by 16 Avengers , 36 Dauntless and fighter escorts. The Japanese tossed 84 fighters but the allies held such a tight formation it was difficult to get at the bombers. 2 bombers were lost before reaching Lakunai; 1 to a mid-air collision and 1 to antiaircraft fire. When the Allied aircraft finally arrived, clouds shielded Lakunai so the bombers switched to targeting the ships in Simpson Harbor. The Avengers carried 2,000lb bombs, limiting their effectiveness. Regardless, they landed hits on the 15,400-ton-displacement oiler Naruto, and thus ended its goal of becoming the Hokage. . . sorry folks could not resist that one. The destroyer Matsukaze was also damaged alongside 5 other vessels. 

 

AirSols came back to hit simpson harbor and blanche bay 3 days later sinking  the Komaki Maru, Kosei Maru, Yamayuri Maru, Hakkai Maru and Iwate Maru. To take down the combined 30,000 tons of shipping AirSols lost 8 P-38s, 1 Hellcat, 1 F4U, 1 Avenger, and 1 Dauntless. The rest of January saw so many raids, sometimes 2-3 on the same day, thus I can’t spend the entire podcast listing their actions, but the losses were brutal. For the Americans they would lose 23 aircraft between January 23rd-30th, for the Japanese it was around 37. By the end of the month, Rabaul was being bled dry of planes, thus the rest was withdrawn to Truk with around 40 pilots. To make up for the withdrawal, Admiral Koga brought over the air groups of carriers Junyo, Hiyo and Ryuho on the 25th adding 62 zeros, 18 vals and 18 kates to Admiral Kusakas dwindling forces. Does that not sound like performing the exact same action that saw such devastating losses in late december to early january? Yes, yes it does. 

 

Moving over to New Britain, General Shepherd had just smashed the Japanese positions along Suicide Creek. While seizing Suicide Creek some Americans captured a Japanese dispatch saying “It is essential that we conceal the intention that we are maintaining positions on Aogiri Ridge. Concerning the occupation of this position, it is necessary that Aogiri Yama is maintained.” While making arrangements for the Japanese assault against Target Hill one, Lieutenant Abe had occasion sent field dispatches to Warrant Officer Kiyoshi Yamaguchi, one of his platoon leaders. The dispatch mentioned command post locations, hour of attack, and other orders. Yamaguchi, with that seemingly incredible indifference to basic security which the Japanese so often demonstrated, simply stuck the dispatch in his pocket and carried it with him to the assault. Marines found it on his body the following morning, thereby gaining their first inkling of the existence of a terrain feature which appeared as such on none of their maps but upon which the Japanese appeared to place great importance, for reasons not yet clear.

Aoigiri Ridge was not in the American maps and it was currently held by the 2nd battalion, 53rd regiment and 2nd battalion, 141st regiment. Behind the ridge was a wide trail leading to Magairapua, connecting Matsuda’s HQ with Borgen Bay. The trail was heavily used and concealed extremely well from American aircraft. Back over at the American lines, by January 5th, the 3rd battalion, 7th marines had pulled back into the reserve, allowing the weapons company, 7th marines to occupy the extreme left along the shore to prepare for Shepherds offensive against Hill 150. The new formation launched their attack at 11am on the 6th. Tanks surged forward to smash a roadblock held by the 2nd battalion, 141st regiment on the left trail. Artillery was deployed on a nearby hill hitting the Japanese lines as A company tried to break through but was quickly pinned down by the roadblock. The tanks eventually burst through the roadblock sending the Japanese packing.

 

The americans advanced through the increasingly swampy terrain, facing weaker resistance. B company crossed a small stream and stormed Hill 150 during the afternoon, securing it. Further right, C company and the 3rd battalion, 5th marines were surprised to be held up by extremely heavy fire from the until then unknown feature, Aogiri ridge. The men had no other choice than to pull back to a safe distance to dig in as they reported back the presence of the heavily fortified position. The Japanese would unleash carnage upon the men for 2 days whenever they tried to press forward. On the 7th the commanding officer of the 3rd battalion, 5th Marines, was wounded and replaced by Lt Colonel Lewis Walt. The next day, Walk’s men were cautiously inching forward under heavy enemy fire through dense jungle, when they first encountered the ground rising in steepness. At this point Walt realized the feature had to be Aogiri Ridge. 

 

On the 9th, the assault battalions resumed their attacks, this time with heavy artillery support against Aogiri ridge. Walt was reinforced with Companies K and L from the 7th marines, but the advance was extremely slow and painful. Two Japanese bunkers were knocked out with white phosphorus grenades, but that ended the limited gains. Walt personally began pushing a 37mm gun excruciating foot by foot up Aogiri ridge, firing a volley of canisters every few feet. Somehow he managed to get the gun up the steep slope into a decent position to sweep the ridge, allowing the gain of a foothold on the crest of Aogiri. The loss of the ridge was a huge threat to Matsuda and Katayama’s positions, so the latter decided to throw his reserves in a desperate but ferocious counterattack.

 

At 1:15am on the 10th, Katayama sent his recently arrived 3rd battalion to attack the reverse slope. However the Marines held firm and would end up repelling 5 consecutive banzai charges with a fury and persistence unparalleled in the campaign. On the 4th try a Japanese major and two company officers succeeded in knifing through the Marine cordon almost to Colonel Walt's fox hole, 50 yards behind the front line. At that instant one of two short rounds in a 60-round artillery barrage burst in a tall tree almost directly overhead, and the major died there, sword in one hand and a pistol in the other. The 5th charge was blunted by artillery and the Japanese finally cut their losses and pulled back. The Japanese had suffered immense casualties, seeing all 3 of their battalions depleted, forcing Katayama to pull off Aogiri ridge that very night. The morning of the 10th saw Walk’s men securing the feature and then discovering the vital Magairapua trail. The marines went to work mopping up the area until January 12th, whereupon Shepherd planned to seize Hill 660. The feature was guarded by the 6th company, 141st regiment supported by a number of guns of the 30th machine cannon company. The fresh 3rd battalion, 7th marines, led by lt colonel Henry Buse Jr were to perform the main assault, with the 1st battalion extending the perimeter behind them. To help the effort, the weapons company,7th marines of Captain Buckley would begin constructing a roadblock between the eastern base of Hill 660 to the shore of Borgen Bay, hoping to cut off the defenders escape route.

 

At 08:00am on the 13th, after artillery, mortars and the 5th Air Force performed a bombardment of the area, the last Marine offensive commenced. A intricate system of small arms and automatic weapon positions going up the summit unleashed fire upon the marines, quickly pinning down I company. L Company attempted swinging to the right, but were also pinned down. Engineers worked a light tank forward far enough to place fire across a gorge demolishing the more troublesome enemy weapons. By late afternoon, together with artillery supporting fire, the pinned-down companies were rescued and withdrawn for the night. Meanwhile the Weapons company worked with their bulldozer, by 1030 they had skirted the eastern base of the hill and set up an all-around perimeter. There they dug in clearing fields of fire for about 60 yards to both north and south, placing their half-tracks and tanks in supporting positions. The only opposition they encountered during the advance was by two Japanese machine guns and emplaced near the summit of the hill. With all said and done they successfully cut off the Japanese line of retreat. 

On the morning of the 14th, the 3rd battalion resumed their assault, with their leading companies advancing to the right working their way up. One unit nearly got atop the crest before coming under fire from heavy machine guns. They got to a position where they could bring 60mm mortars to bear, and went to work neutralizing the machine gun positions before a final surge carried them across the summit. The Japanese fled down the crest heading east, coming straight into the line of fire of the Weapons company below. The result was a terrible rout, seeing many escape to the safety of the swamps to the hills southeast. By the end of the 14th, the marines had seized Hill 660 and were performing mop up operations through the following day. At 5:30am on the 16th, Katayama ordered the 6th and 11th companies, 141st regiment to counter attack Hill 660. Soon the marines were face to face with a large banzai charge, seeing the fighting getting up close and personal. But small arms, rifles, 60mm mortars and 81mm artillery broke the Japanese. Over 110 Japanese bodies would be found after the fight. This ended Shepherds offensive, as the remnants of Colonel Sumiya’s forces began to arrive to the Borgen Bay area. Over the next few days, the exhausted 7th marines were relieved by the 5th marines and 2nd battalion, 1st marines who had recently been recalled after completing their mission at Green Beach. 

After suffering the defeated in Borgen Bay, General Sakai decided to order the 1st battalion, 54th regiment to reinforce Talasea and for Matsuda to launch a last ditch effort, a suicidal one at that, to obliterate the enemy. But the men were in no condition for such an offensive, thus Katayama elected to postpone it for now. Since every man was needed for the defense of Borgen Bay, Colonel Sato took the remainder of his commander and departed Rooke Island to join the main body. Now that Hill 660 was secured, the Americans began a new method of patrolling; this time their patrols would specifically seek out and destroy what was presumed to be exhausted Japanese units, before the division would attack the defensive line at Borgen Bay-Itni river. Yet that is it for new Britian, as we are going to be traveling over to the CBI theater.

Between November 22 to December the 1st, two conference were held between the Allied leaders. The first was the Cairo or “sextant” conference on November 22-26th, between President FDR, Sir Winston Churchill and Chiang Kai-shek. The second was held in Tehran on November 28-December 1st between FDR, Churchill and Joseph Stalin. You might be asking, why did they all not meet up together. The crux of it was the Soviet-Japanese neutrality Pact and to a lesser extent, though probably not in Chiang Kai-Shek's mind, Stalin was aiding the CCP. Because the Soviets had not declared war on the Japanese, it would not look to good if they met with the leader of China, likewise Chiang Kai-shek was not too forthcoming to meet with Stalin. The easy fix was to just have two different conferences. Overall the conferences did not really touch too much upon the Pacific war. But Stalin did promise to declare war on Japan within ninety days after the end of the European War. In return he demanded military and logistical concessions in Manchuria, maintenance of Outer Mongolia under Soviet control as well as sovereignty over the Kuril Islands that stretched from north of Japan to Russia’s Kamchatka Peninsula. When Chiang Kai-shek heard about this he had suspicious and noted “The influence of this conference on China will be great. I hope Roosevelt isn’t plotting with Churchill and Stalin against me.” Soon his suspicion would turn to anger when he discovered there were secret protocols relating to Manchuria.  Stalin had made some assurances to Mao Zedong that once the Soviets were in the war against Japan, they would have forces to bear down into China to help tip the scale for the CCP against the NRA. Yet after the war, it would seem promises made by Joseph Stalin were not always kept. 

Another important aspect of the conferences was the British decision to cancel Operation Buccaneer, the invasion of the Andaman Islands, because Admiral Mountbatten’s landing crafts were required for landings in southern france. The Joint chiefs of staff were livid at this, because it came at the same time the Japanese were reinforcing Burma. FDR overruled them and agreed to the British decision and this in turn greatly pissed off Chiang Kai-Shek. Yet at the same time, the Cairo declaration had lifted up the morale for the Chinese army and people to continue their war against the Japanese. The declarations made by the Tehran conference implied publicly that the CBI theater was all but abandoned to the mercy of Japan’s air and land forces. Thus it would be no coincidence the Japanese thought it ripe to launch an all-out offensive against China. 

In the meantime, the rather aggressive Admiral Mountbatten was trying to salvage what he could of the situation. To try and please Chiang Kai-Shek, he proposed Operation Pigstick. The operation was something Mountbatten had wargamed a bit, it was to be a landing on the southern Mayu peninsula aimed at hitting Akyab. He began assigning landing craft for the amphibious operation, only to be immediately slapped down by Alanbrooke and told to return 3 fast tank landing crafts that were direly needed for operations against Italy. Mountbatten hoped to retain 2 slower tank landing craft, but Cunningham requested them. Pigstick was to be 2 divisions plus 2 brigades who would be used in a southward advance down the peninsula and 1 division in an amphibious assault aimed at surrounding and destroying not less than 20,000 Japanese. An additional landing similar to PIGSTICK, could perhaps be launched in the Ramree-Cheduba area, could take staging areas that would put 15 Corps within reach of Rangoon. Speaking of Ramree, if any of you have heard this kind of myth about over 1000 Japanese being eaten by crocodiles on that island, over on my personal channel the pacific war channel I did a full investigation into the so called “ramree island massacre” story. A little sad about its performance not going to lie. Dramatically improved my lackluster animation skills for it, came out really well and I did a silly impersonation at the beginning, anyways check it out its a fun one!

Alongside Pigstick, Mountbatten changed the Tarzan operation into Operation Gripfast, calling for an offensive on north and central Burma with an airborne landing at Indaw to sever the Japanese line of communications to Myitkyina. But now Chiang Kai-Shek was very wary of anything British, so he rejected the plans on December 19th. Alongside pissing off Chiang Kai-Shek, his estranged wife, Joseph Stilwell was also again angry with the British, particularly Mountbatten. At one point Mountbatten proposed moving certain American units into the Hukawng valley to help the offensive there and Stillwell burst out ‘I should like it placed on record that I am responsible for the training of all American forces in this theatre and I am the person to decide when they are adequately trained and can move forward.’ Mountbatten replied: ‘I accept that in principle, but would remind you that these troops are being trained under British officers. I am responsible for operations and will decide when units move into the fighting lines. In other words, general, I should like to place on record that I am Supreme Commander out here and what I say goes.’ Stilwell took it good-humouredly and laughed. ‘We none of us dispute that,’”. That day Stilwell wrote a letter to his wife, referring scathingly to Mountbatten as ‘the glamour boy. He doesn’t wear well and I begin to wonder if he knows his stuff. Enormous staff, endless walla-walla but damn little fighting . . . And of course the Peanut is unchanged. The jungle is a refuge from them both.’

The men would all share some screaming matches against another, until Stilwell would shock everyone by exclaiming “I am prepared to come under General Slim’s operational control until I get to Kamaing.” It was a truly bizarre idea, Mountbatten asked how such a thing would work, and both Slim and Stilwell asked to discuss the matter amongst themselves. The two men would agree on tactical essentials such as getting more Chinese divisions for the Ledo force and to use the Chindits to assist in hitting Myitkyina. Slim and Stilwell shook hands and Stilwell said to him ‘I would fight under a corporal as long as he would let me fight.’ Slim would later reflecte ‘In practice this illogical command set-up worked surprisingly well. My method with Stilwell was based on what I had learnt of him in the Retreat – to send him the minimum of written instructions, but, whenever I wanted anything, to fly over and discuss it with him, alone. Stilwell, talking things over quietly with no one else present, was a much easier and more likeable person than Vinegar Joe with an audience. Alone, I never found him unreasonable or obstructive. I think I told him to do something he did not approve of on only two or three occasions, and on each he conformed, I will not say willingly, but with good grace.’ In the end Operation Pigstick never became a reality, because the landing crafts were needed for the Italian campaign and thus the hope of meeting Chiang Kai-sheks continued demand for an amphibious operation was gone. It was almost like the British never intended to go through with such a thing in the first place, woops that is just my opinion.

Meanwhile the British-Indian command elected to start a new operation in Arakan. The brutal hard-won lessons of 1st Arakan battle had been absorbed in India Command, with senior British officers determined to avoid similar mistakes. The new operation was the subject of meticulous reconnaissance, planning, and rehearsals. A series of lectures, war games, models of the grounds and syndicate discussions were held for commanders, staff and regimental officers whom carefully considered countering Japanese offensive tactics and assaulting prepared defensive positions like those witnessed at Donbaik. A carefully planned programme of continuous, progressive and intensive training was put in hand for all corps and divisional fighting, support and administrative troops to practice necessary skills, including using brigade boxes, aerial resupply and the infiltration and envelop- ment of enemy positions. This comprehensive training programme culminated in intensive rehearsals and combined arms training with artillery, tanks and close support aircraft carried out near Lohardaga, over ground resembling Arakan, simulating attacks on mock Japanese defensive positions on jungle-clad hills.

General Auchinleck assigned the 15th corps, reconstituted at Ranchi with the 3 best trained divisions available: Major-General Harold Briggs’ 5th Indian Division; Major-General Frank Messervy’s 7th Indian Division and Major-General Christopher Woolner’s 81st West African Division.The 26th Indian Division formed the corps reserve. Command of the 15th corps would be given to Lt General Philip Christison. The plan called for the 5th and 7th Indian divisions to advance along the summit of the Mayu range towards Maungdaw and Buthidaung while the 5th and 6th west african brigades would provide flanking protection. On November 1st, the 2 Indian divisions began their advance and by mid november would make contact with a Japanese outpost.As the 7th Indian division advanced astride the Kalapanzin River they ran into stiff resistance. Efforts to dislodge Japanese defenders near Awlanbyin and Letwedet, showcased the formidable difficulties that attacking Japanese defensive bunker positions presented. Most were built on razor-back ridges, through which were burrowed fire positions, affording a limited approach, while the reverse slopes protected troops from view and bombardment. With the precipitous Goppe Pass initially only suitable for porters, pack transport and pack artillery, 7th Indian Division quickly devised other methods to overcome enemy defenses, since normal stereotyped, set-piece attacks stood little chance of success without supporting field artillery. Aircraft proved an ineffective substitute, moreover, with dive-bombing having only a transitory effect since the broken terrain and dense jungle absorbed blast leaving defenses and morale largely intact unless a lucky direct hit was made. The Indian forces began to infiltrate and bypass the well-entrenched Japanese defenses, giving the impression they would soon unleash a frontal attack upon them at any moment. General Messervy’s would say of the action  “'We will undoubtedly have a Neapolitan sandwich of British - Japs - British, but it will be one made by ourselves, and with the initiative in our hands it will soon be transformed to British - British - Jap.” They were gaining ground and with it valuable combat experience. On the night of November 30th, the 15th Indian Corps commenced large-scale operations to drive in the Japanese outpost line astride the Mayu Range. A series of brisk skirmishes were fought by 33rd Indian Infantry Brigade on the jungle-cloaked ridges south of Awlanbyin quickly evicting small determined parties of Japanese infantry from carefully prepared platoon and company defensive localities. This was by no means an easy task since most heavily camouflaged positions were built atop steep hillsides overlooking paddy fields that provided an open field of five and difficult going for advancing troops. Earlier directions about infiltration paid off in practice. An attack on Awlanbyin west redoubt from the rear through thick jungle achieved complete surprise. Although a neighboring Japanese position initially held out, its garrison withdrew on 2nd December after being cut off. The 33rd Brigade columns  crossed the Ngakyedauk Chaung and occupied the area from Ngakyedauk village to the ridge about 1.5 miles north-west of Sinohbyin village. By December3rd, they extended the area of operation to the hills overlooking Maungyithaung and Sinohbyin. The 89th Brigade, meanwhile, pushed forward down Tatmin Chaung and established forward positions on the hills south of the chaung, one mile west of Tatmingyaungywa. By mid-month, 7th Indian Division had reached the main enemy positions covering the Tunnels and Buthidaung, and the opening of the Ngakyedauk Pass to wheeled traffic in late December considerably eased resupply and allowed the divisional artillery to join the formation. However, both the Indian divisions were under orders not to get engaged in serious fighting with the Japanese, so the advance stopped there.

It is also important to note, in November 1943,  Spitfires were deployed in Bengal for the first time. The 615th and 617th squadrons were based in Chittagong to protect the vital port and also to cover the Arakan. Within one month, the Spitfires destroyed four Japanese photographic reconnaissance aircraft. Previously, the Dinah’s range, speed and height had enabled them to fly with impunity over the Allied forward bases and the Hurricanes were unable to catch them. The Japanese reacted by sending out fighter sweeps in order to test the Spitfires and whittle down Spitfire strength. However, by the end of December, the Japanese lost 22 aircraft, another 33 were damaged, and the Allied loss was only 13 aircraft. The greatest air battle occurred on the last day of 1943. On that day, No. 136 Squadron destroyed 12 and damaged 11 when a mixed force of Japanese fighters and bombers attempted to attack the light naval force along the Arakan Coast. The Japanese carried out one strategic attack when on 5 December 1943, 60 bombers and fighters, including some naval aircraft, in two waves bombed Calcutta. The Japanese lost two aircraft and another five were damaged. The three and a half squadrons of Hurricane fighters, including half a squadron of night fighters which were defending the area lost five aircraft and another six were damaged. 

To the west the 5th Indian Division had also encountered stiffening resistance from Japanese outposts as it advanced southwards along the coastal plain towards Maungdaw, through the foothills further north and along the spine of the jungle-clad Mayu Mountains. They soon discovered that overcoming Japanese bunker defenses presented particular difficulties. As the division would report "The great difficulty in attacking Jap "hill top" positions lies in the concealment of the actual bunker or weapon pit' one brigade commander later wrote, and in the practical impossibility of deploying attacking troops in thick jungle, particularly where the approach runs along the top of a razor backed ridge.' In each case, patrols infiltrated between these localities isolated them from supplies and reinforcements with the result that Japanese normally gave up ground without a contest. A newsletter prepared by the HQ of 5th Indian Division reported: 'The only way to deal with the Jap def positions is by INFILTRATION. Recent experience has shown that the Jap has produced nothing new in def tactics... It is almost physically impossible in hilly and thick country to have every post covered by another, the posts can be eliminated piece- meal by infiltration tactics.' After the outline of the main Japanese defenses became apparent this approach was also increasingly applied at brigade level. At the end of December 1943, the 5th Indian Division held the area from the sea to the crest of the Mayu Peninsula and the 7th Indian Division moved into the Kalapanzin Valley. By the end of the month they reached Maungdaw.

The advancing 5th Indian Division discovered that frontal assaults could not be completely avoided, however, when Japanese troops were determined to stay put. During this advance, the 161st Brigade moved to the high ground to the northeast of Bakkagona about five miles to the north of Razabil. On 30th December, 161st Indian Infantry Brigade assaulted Point 124, but the 4/7th Rajputs were held up by dense jungle and heavy mortar and machine fire and suffered heavy casualties. For six days assaults continued with the forward infantry regularly reaching the Japanese defenses before being driven off by showers of hand grenades and supporting machine-gun from every other enemy defensive position within range. Only after a 'policy of strangulation, starvation, and attrition was adopted', did its defenders withdraw. The 5th Indian Division immediately began probing the main Razabil defenses, while its 123rd Indian Infantry Brigade patrolled the western foothills of the Mayu Range and northern side of Razabil, particularly two hill positions dubbed Wrencat and Wrenkitten. To do so an indirect approach was again advocated by Major-General Harold Briggs in note on tactical policy issued on 4th January, stressing the importance of patrolling to identify positions held by the Japanese and infiltration to seize vital ground in their flanks or rear that would either provoke Japanese counterattacks or force a withdrawal.

Meanwhile Stilwell arrived to Shingbwiyang on December 21st and assumed command of the Chinese forces in India. To relive the trapped battalion of the 112th regiment at Yupbang Ga, Stilwell and General Sun planned to send the entire 114th regiment to break the Japanese center at Yupang Ga to rescue the 112th, then hook north to envelope the northern fragment of the Japanese defensive line. On December 24th, they unleashed artillery and launched the infantry into the Japanese lines. The 114th regiment managed to envelop the Japanese right flank by the afternoon and soon a breakthrough emerged allowing for them to make contact with the 112th. Sun’s men then surrounded the Japanese pocket during the night and would wipe them out the next morning. And thus the Chinese had gained their first victory at Yupbang Ha, though the Japanese still held the river crossing, so Stilwell began plans for another assault set after Christmas. On December 28th, Sun ordered 3 battalions to attack the north, while the 1st battalion, 112th regiment would sweep to the right, getting behind the 3 Japanese outer strongpoints. The chinese forces rapidly broke the Japanese outer defenses creating a breach while the 1st battalion, 114th regiment broke through the river defensive line. The Japanese tossed a large counterattack, but it would be repelled by the night time. Now Yupbang Ga was in allied hands as the surviving Japanese companies split into smaller groups trying to hold out for many days.

With the fall of Yupbang Ga, the Japanese were forced to withdraw from Sharaw Ga as well, so elements of the 2rd battalion, 113th Regiment were be able to seize it by December 30. In the meantime, as the 22nd Division’s 65th Regiment had been sent towards the Taro Plain to try and secure the southern flank, the 2nd and 3rd Battalions of the 114th Regiment had been sent south to cross the Tanai Hka at the Kantau ford in an effort to cut off the enemy withdrawal line. By the end of 1943, with the loss of 315 killed and 429 wounded, Sun’s 38th Division had gained complete control of the Tarung Hka.

Things were deteriorating for the Japanese on New Britain as American Marines were seizing features and gradually pushing them into Borgan Bay. Within the CBI theater a ton of drama amongst the high commanders was surprisingly not resulting in disaster, as operations in Burma were kicking off with great results. Perhaps Burma could be saved.

- 111 - Pacific War - Landing at Saidor , January 2-9, 1944

Last time we spoke about Operation Backhander, the landings at Cape Gloucester. General Douglas MacArthur unleashed another cog in the machine that was his drive back to the Philippines. The 1st Marines under General Rupertus were back in the action, spearheading the landings at Cape Gloucester. The landings were successful and multiple allied units began advancing towards the airdrome.  Colonel Sumiya realized the futility of attempting a defense upon the open ground against American armor, so he pulled his units away towards Razorback Hill from which they could launch harassment maneuvers against the new American perimeter. Over on New Guinea the Australians continued their drive towards Sio, pushing the Japanese even further north in the process. The Japanese were being attacked in multiple places without the ability to contest them everywhere. What would the Japanese commanders do to establish a proper defense?

Last week we left off with General Nakai unleashing a counteroffensive against Kesawai. The counteroffensive was successful at pushing the Australian commando’s out of the area to prevent them from encroaching upon Madang. These actions worried General Vasey who thought the Japanese might follow them up with an offensive against Dumpu. Vasey elected to carry out a punitive attack along Shaggy Ridge. Perhaps a refresher as I think I did once describe it, but Shaggy Ridge is located six miles north of Dumpu. The razorback ridge has one elevation of more than 5,000 feet, running roughly southeast to northwest. The highest point on the ridge is known as the Kankirei Saddle. There are also three high elevations along the ridge that the Australians named the Pimple, the Intermediate Snipers' Pimple, and the Green Sniper's Pimple. The Japanese had constructed four miles of defenses along the northern part of the ridge. These positions dominated the trail along which the Australians would eventually have to cross. The trail was narrow, only two to three feet wide, and there were drops on either side of 300 to 500 feet. The Japanese had also constructed a rough road on the coast side to a point between the Mindjim and Faria Rivers, making supply to the defenders much easier. The Pimples were the strong points, and the Japanese had built fortified posts with machine guns and deep trenches on each.

Vasey’s punitive force consisted of the 2/16th battalion under the temporary command of Major Garth Symington. Patrols had been sent to figure out decent approaches for an attack against the Pimple, but everything indicated there was only a narrow path to perform a frontal assault from. Thus Symington planned to assault the Pimple and exploit for about 400 yards along the ridge with Captain Christian’s B Company while Captain Anderson’s D Company maneuvered behind to consolidate the ground gained. Fortunately Symington would be receiving aerial support from the American 41st Squadron and Australian No. 4 Squadron, artillery support from the 8th battery and 54th battery and back up from the 2/27th battalion who would launch a diversionary attack against the Japanese along the Faria River and Mainstream area.

During the morning of December 27th, the assault began with 16 Kittyhawks and two Boomerangs bombing the Pimple followed by artillery. Dive bombing, strafing and artillery fire was intense causing reverberation and roars that could be heard up and down the Ramu Valley. An hour later, B Company’s leading platoon departed their startline under the foliage of the rainforest to scale the rock face leading to the pimple. Although the bombardment was stunning, the dazed Japanese defenders quickly responded to the invaders by tossing grenades from the well sited pillboxes atop the pimple. The Australians dashed forward and wiped out the forward pillbox, securing their toehold on the ridge. With the artillery firing further forward the Australians were soon able to capture the second pimple feature just 100 yards ahead, successfully clearing the Japanese from their entrenchments. However at this point, B company came across a strong rock bunker. They first allowed the artillery to smash it, then they tossed grenades while trying to outflank the defenders. A Japanese defender refusing to surrender, covered the entrance to his pillbox with a groundsheet and for about two hours flicked away the grenades thrown at him before they could explode. Eventually he was blasted out when a grenade was tied to the end of a bamboo pole which was poked into the pit, the pin being pulled out by a length of string. More than 100 grenades were thrown during the day at the rock bunker in front of the second pimple. As hard as they tried it was impossible to outflank as the sides of the razorback guarding the bunker were almost perpendicular. Christian was forced to pull B company back and dig in on the second pimple.

Meanwhile, D company came up to relieve the exhausted men of B company. To deal with the bunker menace, Australian Pioneers chiseled a track along the cliff face towards it and designed a special bomb consisting of a grenade placed in a chemical and sealed in a field ration tin. During the morning of the 28th, D company advanced over their newly cut track and hurled the new bombs successfully blowing up the enemy bunker. While this was occurring, Lt Scott’s 18th Platoon was advancing down the eastern slope of Shaggy Ridge attempting a encircling maneuver against the third pimple. At 10.50 a.m Scott reported being at the base of the third pimple and a quarter of an hour later the artillery and mortars began firing smoke to cover his Platoon’s advance. At the foot of the objective Scott ordered his platoon sergeant, Longman, to take a small party of Owen gunners up the third pimple. Under heavy enemy machine-gun fire Longman and three men charged an enemy machine-gun post near the top. Two of his men were wounded but Longman and the other man continued to advance upon the enemy post and eventually silenced it with Owen-gun fire. To reach the enemy post they had to pull themselves up a steep slope with one hand and fire their Owens with the other. Still under heavy fire from other enemy posts the two men covered the evacuation of the two wounded and neutralized the fire of another enemy post 40 yards away which was opposing the advance of the rest of the platoon, led by the wounded Scott, up the cliff face. Nine minutes after Longman led the first assault, Scott was in possession of the third pimple and was covering the advance of Lieutenant McCaughey's 16 Platoon to the fourth and highest pimple, later named McCaughey's Knoll, farther along the ridge. The two platoons then dug in on the newly-won ground. During the afternoon, the battered Japanese attempted a counterattack but were easily repelled, suffering a total of 28 dead during the battle against Symington’s three killed and eight wounded.

 

After the pimples were captured, the fighting fell into a series of artillery duels and patrol skirmishes. With the Pimples in hand the Australians could observe Madang. Vasey at this time acquired further support from General MacArthur who relieved his exhausted brigades with the 18th and 15th brigades. Meanwhile General Adachi sensed key points in the Madang area were not defended well enough, so he ordered the bulk of the 41st division to advance from Wewak to Madang. In early december, the 2nd battalion, 237th regiment and 2nd mountain artillery battalion of the 41st group were deployed at Karkar island. However the movement of the rest of the division was sent to the Gogol area and was heavily delayed by storms that caused numerous rivers to overflow. But now we are shifting gears and heading over to the Huon Peninsula where a new allied landing was about to occur. 

 

In early December, General MacArthur finally decided to act upon a suggestion put forward by his assistant chief of staff Lt General Stephen Chamberlain. Chamberlain argued Saidor on the south side of the Huon Peninsula should be occupied in order to construct an advanced air and naval base. MacArthur waited until two days before the Arawe expedition, before giving orders to Krueger to prepare plans for a landing against Saidor. Because of limited landing craft the landings would need to be pushed until January 2nd. The operation was code named Michelmas and initially it was thought the 503rd parachute infantry could be airdropped over Saidor, but a limited number of aircraft killed this one in the crib. Thus the 32nd division who had been earmarked for the canceled Gasmata landings were chosen for the task. The general outline for the operation was discussed at a conference held on Goodenough island on December 20th attended to be Barbey, Major General William Gill, Whitehead commanding the 32nd division, Colonel Clarence Martin commanding the 126th regiment and other staff officers. Allied intelligence reports indicated the Japanese had few forces in the Saidor region. Nevertheless, the plans called for landings in force on three beaches codenamed Red, White and Blue on the west shore of Dekay’s bay.

 

If the Americans could successfully seize Saidor, this would cut the Japanese retreat from Finschhafen and therefore would trap another Japanese division at Sio. Krueger selected the 126th Regiment for the task after they were rebuilt following the Battle of Buna-Gona and retrained in amphibious warfare. Brigadier-General Clarence Martin would act as the commander of the new Michaelmas task force. MacArthur did not have much time to carry out ground reconnaissance, thus the 3 beaches selected were chosen primarily from aerial photograph data. They would prove to be quite narrow, rocky and exposed to heavy seas. Because the allied intelligence indicated few Japanese forces in the area, MacArthur elected not to perform a preliminary aerial bombardment. 

Admiral Barbey’s amphibious force were now well experienced veterans with amphibious landings, so the last minute notice did not hinder them too much. On January the 1st, Martin’s men were tossed onto 9 APD’s, 17 LCI’s and two LST’s supported by 9 of Barbey’s Destroyers and Admiral Crutchley’s Cruiser force, hoping to intercept some IJN forces. Yet Crutchley would be disappointed as Admiral Koga had his hands full with something cooking up at Rabaul and Kavieng and could not afford to dispense units to Saidor. What could hinder the landings was air forces from the IJA at Wewak, though they were considerably weakened with just 39 fighters, 17 light bombers and 7 heavy bombers available after so many allied air strikes.

 

The landings went off smoothly. The beaches were hit by more than 2000 shells within 20 minutes prior to the first LCV landings at around 7am. Two battalions of the 126th landed abreast without opposition and quickly established a perimeter. Soon a 3rd battalion passed through and extended the perimeter further left upon high ground, just southwest of an unserviceable airfield. Captain Meredith Muggins, who played a key role in the capture of Sanananda, recalled his impressions of this seemingly uneventful landing: 

 

“When we landed at Saidor it was an amazing sight. There were dozens of warships bombarding the coast. The sound was like a rolling thunder and the smoke hung along the ground. As we approached the beach, air attacks began. Heavy bombers dropped their load of high explosive from a few thousand feet. Then came in the B-25 strafers shooting everything in sight, clobbering positions. Behind them came fighters to give the Japs a final working over. There was very little opposition when we landed. We found a few wandering around in shell shock. What a contrast from the days at Buna and Sanananda, only a year before, when we were fighting with rifles, grenades, and rocks!”

 

Thus 8000 troops were landed ashore by the end of the day. The only real resistance came in the form of some air raids from Wewak beginning at 4pm. 9 Japanese Nakajima Ki-49 (Helen) aircraft, escorted by up to 20 Zeros and Kawasaki Ki-61 (Tony) fighters bombed the beach area at 4:30pm. There were three more air raids during the night, and 49 over the course of the month, but most were quite small. Thus on Januaruy the 3rd MacArthur triumphantly stated  “We have seized Saidor on the north coast of New Guinea. In a combined operation of ground, sea and air forces, elements of the Sixth Army landed at three beaches under cover of heavy air and naval bombardment. The enemy was surprised both strategically and tactically and the landings were accomplished without loss. The harbour and airfields are in our firm grasp. Enemy forces on the north coast between Sixth Army and the advancing Australians are trapped with no source of supply and face disintegration and destruction.” The Saidor area and her landing strip were in allied hands and further men and supplies would be brought over without enemy interference.

 

Over on the Japanese side, General Adachi had the understrength and exhausted 51st division garrisoning Sio while the 20th division was retreating from the Finschhafen area. On December 30th, Adachi arrived to Kiari where he ordered the 51st to advance to Bogia, once the 20th had arrived at Sio. Since mid December, some units, such as the bulk of the 66th regiment had already made it to Bogia, where they could be rehabilitated, leaving just the 3rd composite battalion of the 66th regiment, the 3rd battalion HQ, the 10th company and one machine gun company to garrison Gali under the leadership of General Muroya. Just as Adachi was preparing to depart on January 2nd, he received word of the allied landing at Saidor which effectively opened up a new and important threat against his isolated forces. Adachi believed it was now useless to hold on to Sio and the Vitiaz Strait, since enemy troops were also landed on New Britain. Furthermore his main base at Madang was now vulnerable.

Thus Adachi placed General Nakano in command of both divisions now designated the Nakano force and ordered him to advance the forces to Gali by submarine to try and secure the new key supply point while the Shoge detachment would delay the Australian advance to Sio. Nakano would therefore have to break through or bypass Saidor overland to arrive safely at Madang. Additionally the 41st division was ordered to depart Wewak immediately and advance overland towards Madang. General Nakai was given orders to advance his detachment towards Saidor to try and contain the American advance as long as possible and this would only leave the 2nd battalion, 78th regiment under Colonel Matsumoto Matsujiro on the Kankirei Saddle-Shaggy Ridge area.  On January 3rd, Lt General Goro Mano was flown directly to Alexishafen to assume command of all units in the Madang region, including the Matsumoto detachment.

Back over in Saidor, the Americans began to send patrols and an outpost was setup at Sel on January the 5th while the 3rd battalion, 126th regiment skirmished with other American patrols at Teterei and Biliau. General Muroya managed to secure Gali without much difficulty. Meanwhile, upon receiving the news of the Saidor landing, Brigadier Windeyer’s 20th Brigade continued their advance, expecting the march to be a lot easier. After fording the Sanga River on January 3rd, the 2/17th battalion advanced to the Sazomu river while fighting off elements of Colonel Miyake’s rearguard. At this point General Katagiri’s forces were in a full retreat towards Kiari, only performing some rearguard against around Kelanoa. Thus the 2/17th advance went pretty much undisturbed as they reached the Dallman River on January 6th. Kelanoa offered more defensible positions, so Windeyer cautiously sent some patrols to scout the area out, trying to avoid unnecessary casualties. 

At 8 a.m. on the 8th the 2/17th resumed their advance and half an hour later their leading company was met with some fire from a track junction. There seemed to be about 40 determined Japanese with four machine-guns holding the area. The Australians killed 8 Japanese and lost 2 in the process with another 2 wounded. As the company could make no headway without further casualties they withdrew to a kunai patch south-east of the track junction so that artillery mortars and machine-guns could hit the Japanese. The position was hit with mortar heavily causing the Japanese to withdraw during the night. The next day at 9:30am the Australian battalion advanced through the position finding abandoned pill boxes, foxholes and several dead Japanese. Later during the day, a group of 30 heavily armed Japanese fire upon the battalion 1500 yards from the Buri River. The Australians unleashed artillery, mortars and machine guns upon them until 4pm when some tanks arrived forcing the Japanese to flee.

 

Meanwhile the Japanese were able to repair 12 barges which were quickly used to evacuate wounded towards Gali. Unfortunately, allied PT boats were lurking in the area like sharks. The PT boats unsuccessfully attacked Adachi’s submarine that was bringing him back over to Madang but managed to destroy one barge carrying 100 wounded near Herwath Point and damaged others. Most of the wounded would reach Gali by the 10th and 20th division advanced past Kiari on the 9th and were drawing closer to Gali. The 2/17th crossed the Buri River on the 10th and reached the Kapugara river the next day without opposition. General Nakano departed Kiari with his division heading for Gali. It was now only the Shoge detachment that stood in the path of the Australians. The Shoge detachment received orders on January 13th to withdraw towards Sio using an exhausting inland route going from Nambariwa to Nokopo. The Australians would soon enter the ruins of Nambariwa finding the Japanese had destroyed numerous large dumps. Nambariwa had been the principal Japanese supply base for the Finschhafen area, both banks of its river had been barge loading points. There were numerous facilities such as barge workshops, engineer store dumps, hospital areas and bivouac areas. By January 15th the Australian forces would occupy Sio uncontested.

 

General Wootten’s 9th division had completed its mission and it would be their last action in New Guinea. Wootten had received word in early January that the 8th Brigade led by Brigadier Claude Cameron was being brought over to Finschhafen to relieve the 24th Brigade. Now with the fall of Sio, General Berryman ordered the 5th division now under the command of Major General Alan Ramsay to take over the forward area. Mop up operations would continue for a week, until the 4th battalion, 8th brigade and 5th division officially took over Sio. The advance from Fortification Point to Sio saw the 20th Brigade suffer 3 deaths, 13 wounded and 958 sick from malaria, mosquitoes remaining a larger foe than the Japanese as usual. The 20th brigade had marched 50 miles in 24 days and counted a total of 303 dead Japanese and captured 22. Within the 4 months campaign going back to September 22nd, Wootten’s 9th division had suffered 283 deaths and 744 wounded, but estimated they killed 3099 Japanese, captured 39 and inflicted around 4644 wounded. Now we are heading back to the boys on New Britain.

With the airdrome secured and a strong defensive perimeter surrounding it, General Rupertus radioed the commander of the 6th Army “First Marine Division presents to you as an early New Year gift the complete airdome of Cape Gloucester. Situation well in hand due to fighting spirit of troops, the usual Marine luck and the help of God…” General Krueger expressed himself as "delighted." At his advance headquarters at Port Moresby General Douglas MacArthur, presented the airdrome to the people of the United States with his compliments and sent Rupertus the following dispatch: “I extend my heartiest congratulations to your officers and men. I am filled with pride and gratitude by their resourceful determination in capturing Cape Gloucester. Your gallant Division has maintained the immortal record of the Marine Corps and covered itself with glory.” General Rupertus raised the US flag on an improvised staff above the main strip with simple ceremonies on December 31. Soon American engineers were being brought over to repair the airfield as the Japanese sent nightly air raids to hamper these efforts. The Japanese still held several operational airfields within range, but their efforts to bomb the Americans positions were hampered by terrible weather. They also never massed air forces to attack in great strength, thus the damage was always minor and easily repairable.

To the east, assistant commander of the 1st Marines, Brigadier General Lemuel Shepherd assumed command of the forces within the Yellow Beach perimeter. Due to the lack of Japanese resistance around the airdrome, the Marine commanders were convinced General Matsuda was retaining the bulk of his strength in the Borgen Bay area, thus leaving Colonel Sumiya out to dry. Shepherd elected to take his force and use them to clear up the Borgen Bay area. On January 1st he proposed to hold fast on the left and center of the Yellow Beach perimeter, while his right line consisting of the 3rd battalions of the 7th and 5th Marines would advance southeast. On the other side, Colonel Katayama had just arrived at Magairapua with his 2nd battalion on January 1st. It seems at this point Matsuda made an error. Perhaps its because he was essentially a transportation expert rather than a combat leader, perhaps it was due to his failed initial attacks, but he decided to place Katayama in command of all the forces in the Brogen Bay area. Now designated the Katayama detachment, these forces were the 2nd battalion, 53rd regiment and 2nd and 3rd battalions 141st regiment.There would also soon be Major Tatsumi Asaschichi’s 3rd Battalion who were still en route from Nigol and Cape Bushing.

Katayama first tackled his command by underestimating his enemy’s strength. Katayama ordered an offensive in force against Target Hill to be led by Captain Mukai Toyoji’s 2nd battalion, 141st regiment. Major Takabe Shinichi’s 2nd Battalion, 53rd Regiment, would attack the center of the marine perimeter to confuse the Americans and prevent them from reinforcing the hill. At this time Target Hill was being defended by the 1st Battalion, 7th Marines, more particularly their A Company . This unit was deployed with its 1st Platoon defending the area on the left between the beach and swamp, the 2nd Platoon holding a series of strong points on such dry ground as could be found in the swamp itself, and only the 3rd Platoon on the hill proper. Unbeknownst to Katayama, Shepherd had begun his offensive at 10:00am on the 2nd. The 3rd Battalion, 7th Marines, under the temporary command of Lieutenant-Colonel Lewis B. Puller and 3rd Battalion, 5th Marinesunder the command of Lieutenant-Colonel David S. MacDougal were advancing abreast southeast towards Suicide Creek.

The terrain they were traversing was particularly brutal. The 3rd battalion had to hack their way through the jungle going some 300 yards where they would come across well prepared Japanese positions. The 5th battalion had a longer distance to travel, but would encounter less resistance at the early phase. The 5th battalion attempted an encircling movement from the west, the assault troops soon encountered the face of the same Japanese pocket that was holding up the 3rd battalion and were halted in turn. As a result, the attacking lines on the night of 2 January, and throughout 3 January, resembled a huge letter "U", with the enemy strong point contained on three sides.

Recognizing Suicide Creek was a major obstacle, the Japanese had sited their positions skillfully to cover it. Time after time Marines attempted crossings, only to be fired upon from invisible positions. The Japanese had become experts at field fortifications.  The jungle curtailed both their attackers' freedom of movement and enhanced their own concealment: Marines would need get within just a few feet of the emplacements in order to locate them, by which time few were left alive to spot them for others. Even their lack of fortification materials--cement and steel reinforcing--reacted in favor of the Japanese, for the earth-and-log bunkers which they improvised were too soft-surfaced to detonate bazooka rockets, the heaviest weapons the infantry was capable of bringing to the point of contact. To support these bunkers, they had dug deep foxholes between and under the flaring buttress roots of the giant trees characteristic of the region, camouflaging them with foliage and cutting cunningly interlocking fire lanes. Artillery and mortar shells and air bombs were all but useless in reaching these positions, owing to the fantastically high forest cover that usually caused tree bursts, to which the deeply dug-in enemy was virtually invulnerable. The marines gradually surrounded the well prepared positions of the 2nd battalion, 53rd regiment during the night, but they could do little else as each attack brought failure. 

 

Under the cover of darkness and Marine mortar fire, Katayama’s assault troops and engineers hacked their way to the lower slopes of Target Hill. They did their best not to make any noise as they attempted scaling it, but the Marine defenders heard them. On January 3rd  they launched their attack, unleashing artillery, mortar and 20mm machine cannon fire from below the hill. However most of the artillery missed the hill altogether, and the 20mm cannon fire was not causing much damage. Company D's mortars replied from their positions behind the hill, but the high angle of fire precluded effective damage to the advance enemy elements which had actually worked their way to positions about 20 feet from the Marines' front emplacements by then. Katayama’s 5th company leading the assault fought bravely and with great determination, but against the steep terrain and inadequate support, against a very alert enemy proved too much for them. By dawn the attack had died down and the 5th company was virtually annihilated. Further to the west, the 53rd regiments secondary attack had achieved little more and suffered heavily for it. The Japanese were now trying to resist Shepherds attacks along the Suicide Creek while engineers of the 17th Marines were building a corduroy causeway across the coastal swamp to enable tanks to come into the action. By the morning of the 4th, following a 15 minute artillery bombardment, the first Sherman wallowed through the shallow water and mounted itself on the opposite bank. Soon the other Shermans followed and their 75mm guns began to absolutely devastate the Japanese emplacements from point blank range. Shepherd’s assault battalions surged forward across their whole front, encountering no further opposition. Encouraged by the victory and the apparent death or withdrawal of all Japanese in contact to the immediate front, General Shepherd ordered the advance to continue, changing direction to south-southeast. Meanwhile, the 2d Battalion, 7th Marines, pinched out by the successful sweep of its former front and the tying-in of 3rd battalion and  1st battalion on their left, executed a wide swing inland, made contact with the right of 3rd battalion, 5th marines extending the line westward. By the nightfall, Shepherd held a 4 battalion strong front against Katayama’s positions at Aogiri Ridge and Hill 150.

Operation Michaelmas, the landings at Saidor were a great success, forcing General Adachi to shift numerous units around, scrambling to remedy the situation. Yet with so many Japanese units trapped, isolated and continuing to retreat north, would they ever be able to halt the allied advance?

Last time we spoke about the aftermath of the Arawe landing and the drive towards Sio. The Komori detachment did everything they could to bottle up the new American beachhead at Arawe. Meanwhile after the fall of Wareo, the Australians decided it was time to drive towards Sio. General Katagiri had just got his men to Sio, but would have little time to prepare defenses as the Australians were quick on their heels. Likewise the Australians were also expanding past Dumpu, seeing multiple patrols fan out, probing for where the Japanese were massing their forces. In Tokyo, Hideki Tojo invited Japan’s allies for the east asian conference, reiterating Pan-Asia unity against the west. Yet for all the talk, in reality Japan sought to dominate its Asian allies, really as a means to an end. In Cairo the allies held a conference of their own, trying to keep Chiang Kai-Shek in the fold.

General Douglas MacArthur faced daunting challenges during the Pacific War. One of these challenges was in the shape of Rabaul, one of Japan’s strong points from which she exerted force in the region. To neutralize Rabaul, MacArthur sought to seize some airfields in Western New Britain, but to do this would also require securing control over the Vitiaz strait between New Britain and New Guinea. General HQ sought to use airfields at Cape Gloucester and on the south coast to help neutralize Rabaul. Thus Operation Dexterity was born. It was to be twin landings against originally Gasmata, but then for necessity changed to Arawe and Cape Gloucester. This was but a cog in the major plan within MacArthur’s mind to return to the Philippines, one could argue within a greater plan for the white house.

The landings at Arawe were largely successful and with that in hand General Krueger felt his Alamo Force could now launch operation backhander. The battle-hardened 1st Marine division was earmarked for the landings against Cape Gloucester. It was to be their first action after a prolonged period of rest and recuperation in South Australia following their heroic campaign on Guadalcanal. The 1st marines were now under the command of Major-General Rupertus. You probably could not ask for better men for the job, they were well refreshed physically, mentally and militarily. They had acquired an enormous amount of experience on Guadalcanal and with it a high degree of morale. The marines began training with the new types of landing crafts available to them, things they did not have during the Gaudalcanal days.

Meanwhile Krueger carried out a programme of reconnaissance based on aerial photography, mosaics, older maps and some amphibious patrolling. There were 3 Australian officers who played key roles aiding in the effort. The first was Major John V. Mather, AIF, a former labor contractor in the Solomons who had been attached to the 1st Division for the Guadalcanal operation. He remained an integral component of the D-2 Section, where his proficiency with Pidgin English and grasp of native psychology proved most useful. The second was Sub-Lieutenant Andrew Kirkwall-Smith, RANVR, one of the versatile islanders who could turn his hand to nearly anything, and who had been a coastwatcher in the Cape Gloucester region at the time the Japanese first moved in. The third man and the one most more familiar with the ground and inhabitants was the Reverend William G. Wiedeman, who had operated the Anglican Mission at Sag Sag for several years prior to the war and, like Kirkwall-Smith, he was a commissioned Navy lieutenant to give military status to his present activities.

A number of amphibious patrols was performed by the Alamo scouts. The first patrol was led by 1st Lieutenant John D. Bradbeer, who set out for New Britain's western coast by PT boat on September 24th. Around midnight, he cut the motors off on his PT boat around a mile off Grass Point, and his scouts paddled in from there in an inflated rubber boat, landing on a beach at the mouth of the second stream to the south at 0100 on the 25th. After hiding their craft with great care, they proceeded inland through dense secondary jungle growth up the western slopes of Mt. Tangi. There they found enemy defenses in the vicinity of Aisega. After this they turned northward heading through heavy foliage to the upper Gima River and there interrogated the inhabitants. The natives had been excluded from the airdrome area and the coast since the previous July, but they had some information to impart. There was a motor road connected Ongaia and the airdrome, and 12 to 14 Anti aircraft guns were emplaced between these two points; radio stations were located at Aisega, the airdrome, Sakar Island and Rooke Island; barge traffic was heavy on the Itni River and along the coast. Relations between the native population and the Japanese had deteriorated to a low level, although a few quislings still operated in the area. The natives related that the enemy expected an invasion of the Cape Gloucester region. Finally, they retraced their steps; and in the early morning hours of 6 October the Alamo Scouts climbed on board the waiting torpedo boat and returned to Goodenough Island to make their report.

The next significant patrol was carried out on the night of 14 October by Captain W. A. Money, AIF, two other Australians, a Marine sergeant and six natives went ashore about one mile south of Higgins Point on Rooke and remained there until the early hours of 26 October. Captain Money reported there were few Japanese on the island, which doubtlessly influenced the later decision to defer a landing there. Shortly before midnight on November 20th two PT boats throttled down to a halt just south of Dorf Point on New Britain's west coast. Eleven men aboard had the general mission of reconnoitering the beach for an offensive landing, but more specifically they were to study beach approaches, beach conditions and inland terrain between Potni and Sumeru. They were commanded by Major Mather. With plans carefully laid the men stealthily made their way ashore, but luck under such conditions could not always hold up, and the Japanese became aware of the patrol's presence almost as soon as it reached the beach. Thirty minutes after leaving the PT boats, they were back on board, but in that time they had obtained enough information to declare the beach unfavorable for a landing operation. The significant patrol occurred on the night of 21 December, and was done to study two beaches at Tauali. Once again Major Mather acted as overall commander. Splitting the patrol into two seven-man groups, Bradbeer took the first on a reconnaissance of "South Beach" while First Lieutenant Joseph A. Fournier of the 1st Marines took the other for a look at "North Beach." The patrol recommended the latter as the more favorable of the two for a landing. It was duly labeled Green Beach, and 2d Battalion, 1st Marines, made its D-Day amphibious operation there. Such amphibious patrolling helped Krueger figure out where not to land.

Meanwhile the 7th fleet had just come under the command of Admiral Kinkaid and was assigned the naval responsibility for the Gloucester landing. Admiral Barbey would have at his disposal 12 destroyers, taking the USS Conyngham as his flagship, 3 minesweepers, 10 APDs, 16 LCIs and 24 LSTs for the main landings; with another two destroyers 14 LCMs, 12 LCTs and two rocket DUKWs for the secondary landing on Beach Green at Tauali. Covering them would by Admiral Crutchley’s task force 74 consisting of 4 cruisers, 8 destroyers and two rocket LCI’s.

The 1st echelon carried by the APDs Stringham, Crosby, Kilty, Dent and Ward was the 3rd Battalion, 7th Marines; and APDs Brooks, Gilmer, Sands, Humphreys and Noa would carry the 1st Battalion, 7th Marines. The 2nd Echelon of six LCIs would carry the 2nd Battalion, 7th Marines; and four LCIs for the 3rd Battalion, 1st Marines. The 3rd Echelon was seven LSTs, each carrying 500 troops of 1st Marines and 150 tons of supply, escorted by destroyers Drayton, Lamson, Mugford and Bagley. The 4th Echelon was seven LSTs, each carrying 480 troops of 1st and 7th Marines and 150 tons of supply The 5th Echelon was five LSTs, each carrying 240 troops of 12th Defense Battalion and 250 tons of supply. And the 6th Echelon was five LSTs, each carrying 250 Marine engineers and 250 tons of supply.

 

For air support, General Kenney assigned Brigadier-General Frederic Smith’s 1st Air Task Force (FATF). The FATF contained about ⅓ of all the squadrons in the allied air force. It had flown fighter and bomber missions for all ground operations excluding those in the Ramu valley. To support the coming offensive, between November 19th to December 13th, 1241 tons of bombs were dropped over Brogen Bay. For the next 11 days, daylight bombings were intensified with over 1207 bomber sorties being performed, dropping more than 2684 tons of bombs.Their favored point of attack was Target Hill because it was so easily discerned. Gun positions at the airstrip were also given attention, with eighty 2,000-lb. bombs being dropped on 17 December. A few direct hits were claimed on gun positions. Bunkers and supply dumps, protected from view by the lush jungle growth, were fairly safe from air attacks, but the lines of supply suffered heavily. Daylight runs were not all that was performed, simultaneously the allies introduced harassing night tactics as well, to keep the enemy under additional mental strain. You see the Japanese anti-aircraft teams and pilots tried to sleep at night, but the B-24’s would continuously drop bombs, grenades and even beer bottles over bivouac areas simply to keep them dazed.

 

On December 21st, a final rehearsal was carried out at Cape Sudest and 3 days later, Colonel Julian Frisbie’s 7th marines boarded Barbey’s vessels at Buna Harbor. On Christmas day at 6am the convoy was moving. At 4pm the convoy rendezvous with Colonel William Whaling’s 1st marines at Cape Cretin while the 2nd battalion reinforced with H battery of the 11th marines proceeded to Beach Green in their own smaller convoy. 

 

However, as they made their way towards their objective, the main convoy was spotted by a Japanese reconnaissance plane. The convoy would arrive at its destination unmolested. Commander of the southeast area fleet, Admiral Jinichi Kusaka had incorrectly assessed the convoy was bound for Arawe bearing reinforcements and as a result ordered a heavy air strike against the Arawe area instead of Cape Gloucester. At 6am on the 26th Crutchley’s cruisers and destroyers began a naval bombardment followed up an hour later with Smith’s B-24’s, B-25’s and A-20’s. The 5th air force had tossed B-24’s from Dobadura who dropped their payloads all the way from Target Hill to Cape Gloucester. The B-25 medium bombers followed this dropping their heavier loads and the A-20’s focused on the landing areas making sure to strafe the beaches until the first wave would be just 500 yards away.

 

For the next hour and a half the landing craft launched towards the beaches. Two LCI’s outfitted with multiple rocket launchers led the first wave. A considerable amount of smoke screen was set over the area, hindering some of the landing craft from finding their marks. One group carrying elements of the 3rd battalion, 7th marines missed their beach altogether and hit the shore some 300 yards further west. The 3rd battalion led by Lt Colonel William Williams landed at Yellow at 7:46, with Lt Colonel John Weber’s 1st battalion doing the same at Yellow 2. The men charged down the lowered ramps of their LCVP’s seeing marines find unmanned trenches, abandoned guns and a handful of scared shipping engineers cowering in dugouts, too stunned by the naval and aerial bombardments to fight or flee. 

 

The allies had achieved tactical surprise as Matsuda was not expecting an invasion to come to these beaches. Major-General Iwao Matsuda’s had deployed his 53rd regiment around the Tsurubu airdrome and Natamo Point. Storming forward, the 3rd battalion reached a region known as the “damp plat” which according to one Marine “was 'damp' up to your neck”. To the Japanese this was known as “swamp forest” and it held some of the most treacherous terrain, thus the Japanese did not expect the enemy to come by it. The forward momentum was beginning to peter out as men were wading through thick mud, with vines tearing at their bodies. A heavy congestion hit the beaches, greatly hamping the unloading process. As the men advanced, trees literally fell around them, rotten to the core from the bombing. The first marine casualty would actually be a result of a falling tree.

 

Meanwhile the 1st battalion advanced towards Target Hill and Silimati Point. Company B seized their key elevation points by noon. Behind these men came the first echelon of LSTs bearing the 2nd battalion led by Lt Colonel Odell Conoley. They beached their LCI’s and drove straight inland some 900 yards through mud and water all the way up to the center of the new beachhead perimeter on a patch of dry ground. At 2:30 after the LST’s were pulling out a force of 25 Vals and 63 Zeros emerged at low altitude who made a very fast bombing and strafe run against the beaches and shipping. The back and forth firing from the Japanese aircraft and allied forces was intense.  A formation of FATF B-25s, coming in at treetop level, suddenly found themselves snarled up with the Japanese flight almost directly over the beach. In the excitement, two were shot down by friendly fire and two seriously damaged before the gunners aboard the LSTs could cool their trigger fingers. Possibly because they wanted to jettison their explosives, or possibly because they mistook their target, the B-25s then proceeded to bomb and strafe the Silimati point position occupied by 1st Battalion, 11th Marines, killing one officer and wounding 14 enlisted Marines. One correspondent had this to say "the most inexcusable small scale blunder of the war." The Japanese attacked Barbey’s vessels covering the retreat of the first echelon of LSTs tangling with allied CAP. The destroyer Brownson was sunk, destroyers Lamson, Shaw and Mugford were damaged and two LSTs were driven off. 13 vals and 4 zeros were destroyed, for the allies it was 4 fighters and 3 B-25’s. Meanwhile the 3rd battalion was still securing its right flank as Whaling’s 1st Marines supported by Sherman tanks were coming up behind on LCI’s. Their commander landed at 10:15 with the division command post in operation ashore within the hour as the 1st marines drove towards the airdrome.

Lt Colonel Joseph Hankins 3rd battalion ran into one of Colonel Sumiya’s roadblocks. It consisted of 4 fortified bunkers with machine guns and a system of rifle trenches manned by  1st, 2nd and 1st Machine-Gun Companies of the 53rd Regiment. The assault was quickly shattered. K company lost its commander and executive officer in a matter of minutes. Everything seemed to go wrong. Bazooka rockets did not explode in the soft earth covering the bunkers; flamethrowers malfunctioned and an LVT carrying ammunition got wedged between two trees. The Japanese defenders were so amped up seeing the chaos, they rushed out of their bunkers trying to swarm the trapped LVT. They managed to kill two men manning its machine guns, but the driver refused to lose his head and skillfully drove the vehicle right over the nearest bunker providing infantry to storm behind him with grenades. The daring LVT maneuver allowed the men to take the bunkers, stealing victory out of the chaos.

Behind them was Whaling’s 1st battalion led by Lt Colonel Walker Reaves who were bogged down in the damp flat. Whaling quickly changed his plan of advance as a result. He ordered his 3rd battalion to advance in a column along the narrow shelf of firm ground while the 1st battalion covered their left rear, speeding up the progress. Yet as the 3rd battalion moved out to expand their perimeter westwards, Sumiya’s men began infiltrating unoccupied gaps, forcing Colonel Julian Frisbie to recall his Marines and wait for reserves to pull up. By nightfall Frisbies Marines had secured the beachhead. The landing was so well scheduled that the big LSTs began dropping their ramps on the beaches 40 minutes after the first assault waves had landed. By 1pm, they had unloaded and cleared the area to make way for the second echelon. However, close encroachment of the "damp flat" greatly curtailed the area available for dump dispersal and necessitated some hurried improvising by the Shore Party. According to an officer of the 1st Motor Transport Battalion: “The true cause of the traffic congestion can be attributed directly to Army personnel who manned 150 odd 6x6 trucks with preloaded cargo. These drivers had been scraped up from an artillery regiment in New Guinea and supplied with salvaged trucks into which had been loaded practically all the supplies. The trucks theoretically were to discharge their cargo at the dumps, return to the LSTs they had debarked from and return to New Guinea for the second load. The plan failed in one respect, as there were no immediate dump areas to unload the trucks in due to the "Damp Flat." It was decided to leave the cargo in the trucks until dump areas were established. This caused consternation in the ranks of the Army drivers, who consequently abandoned their trucks in an effort to get back on the LSTs… This naturally left 150 trucks stranded on the beach exits for quite a time. Eventually the trucks were unloaded by Marines and proved to be a big aid to transportation starved organizations.”

Meanwhile Whalings battalions set up their own perimeter for the night with both flanks on the beach, a technique they repeated each evening until the airdrome was captured. Further to the west Lt Colonel James Masters 2nd battalion, 1st marines with H battery of the 11th marines codenamed STONEFACE group landed at Beach Green at 8:35. By 10am they had established a perimeter; E company held the left, G company the center and F company the right. The H battery unit was unable to emplace its 75mm pack howitzer satisfactorily on the rugged jungle terrain so they reorganized themselves into 3 platoons of infantry and took up a mobile reserve at the front line. Stoneface’s task was to cut off the coastal road. When Masters men looked around they found the beach completely unoccupied, numerous positions had been abandoned with their weapons. Masters figured the defenders must have fled to the hills during the bombardment, so he ordered patrols to fan out. The only contact made that day was a small group roughly 1000 yards north of the beachhead near the village of Sumeru seeing a small firefight. Yet unbeknownst to Masters, Sumiya had sent a provisional unit consisting of elements of the 3rd and 4th companies, 53rd regiment with the 3rd battalion ,23rd field artillery regiment to drive out the marines via a secondary road east of Mount Talawe. The force was led by 1st Lt Takeda, and was thus called the Takeda Provisional battalion

For Barbey the first day saw 13,000 troops and 7600 tons of materials landed on either side of the cape. However many men had landed in swamps so dense and deep that maneuvering out of such areas was quite difficult. General Matsuda was well aware of this and seized the opportunity. Matsuda ordered Colonel Katayama to leave token garrisons at Aisega, Nigol and Cape Bushing while he brought the bulk of his 141st regiment to Magairapua, this would take until December 30th to occur. Yet Matsuda had made one mistake, he thought he was facing just 2500 men. How the 65th brigade staff came to this conclusion is unknown. Perhaps it was became the smoke screen during the landings had made visual observation limited; perhaps the loss of Target Hill so fast also limited further observation of the enemy. The Marines had achieve tactical surprise by landing on undefended beaches, but other than that, they did not do all that much on the first day, perhaps the lack of activity also factored in Matsuda’s head. The only real fight of the day had been a brief affair at the roadblock where the invaders, instead of throwing infantry frontally against powerful bunkers in the glorious banzai manner, had awaited supporting weapons to knock out the position. Perhaps to Matsuda this spelled weakness or timidity, or both. Regardless, like most Japanese commanders Matsuda was obsessed by the then-current Japanese doctrine of "annihilate-at-the-water's-edge," so he ordered his own major assault unit hurled in an all-out attack against the center of the invaders' perimeter.

Thus instead of reinforcing Sumiyas forces at the airdrome, or withdrawing forces to more defensible areas like Borgen Bay, or even waiting for Katayam’s troops to arrive, Matsuda decided to make a daring attack directly at the center of the marine perimeter with only his 2nd battalion, 52rd regiment.

 

At 3am on December 27, the Japanese attacked the sector held by the 2nd battalion, 7th marines, during one of the worst monsoon storms the Americans had ever seen. Because of the storm, many of the Japanese failed to find gaps existing on each side of the battalions flanks. Thus instead the Japanese hurled themselves frontally against very well dug in positions. By 7am, the surviving Japanese finally began to pull out, Matsuda’s men suffered 200 deaths with over 100 wounded. The Marines suffered 8 deaths and 45 wounded, added together for the day the total loss for the Americans was 28 deaths and 68 wounded. After Matsuda’s terrible defeat, Whaling’s battalions resumed their drive towards the airdrome. While they advanced in columns along the road, patrols were sent into the jungle to hunt down the enemy, but they encountered no resistance. The 1st marines were able to dig in for the night after advancing 5000 yards.

 

To the east, Frisbie’s 2nd battalion had expanded their perimeter towards the bank of Suicide Creek where they would continue to face short and sharp attacks by Matsuda’s 2nd battalion. Despite the heavy punishment he was served, Matsuda continued to believe in the destroyer-at-the-water’s edge tactics. His men began constructing defensive positions, bunkers, trenches, rifle pits and so forth, so close to the American lines the Americans could hear them doing it. Meanwhile the engineers of the 17th marines performed their own work, widening the Japanese coastal road to allow the movement of supplies. Despite their valiant work, the volume of traffic was immense, coupled with the storm made the narrow coastal road a logistical nightmare. 

 

The next morning the Marines expected to encounter some heavy resistance. The marine artillery crews increased their rate of fire and General Kenney’s aircraft bombed Colonel Sumiya’s strongpoints. With tank support, Whaling resumed his advance at 11am, with Company I finally hitting the first enemy positions about 12:15. They ran into a Japanese strong point consisting of a system of mutually supporting bunkers and rifle trenches, well armed with anti-tank guns and 75mm guns. The way forward was littered with land mines and barbed wire. The defenders enjoyed an added advantage in the heavy jungle lying a short distance inland which limited the tanks' field of maneuver to the comparatively narrow area directly to their front, facing the flank of the Japanese position which thus became, in effect, a defense in depth for the entire extent of its east-west length: approximately 300 yards.

 

At 12:00, I Company was fired upon with small arms from the front, followed by 75mm shells along the road area. 15 minutes later the leading elements led by Captain Carl Conron began attacking the fortifications alongside the tanks. They were facing the  2nd Company, 53rd Regiment and the 1st Machine Gun Company, 53rd Regiment and the strong point was quickly nicknamed Hell’s Point. Later it would be renamed Terzi Point in honor of Company K’s commanding officer who died on the landing day. Within the heavy rain, the tanks surged forward and smashed Sumiya’s bunkers, while A company dashed to the left, emerging from kunai grass just 500 yards from the bunkers. Enjoying excellent cover, the defenders’ fire successfully stopped the American advance, although the Marines themselves also easily broke up two Japanese frontal assaults and one attempt to turn their flank. 

 

Ammunition began to run low, forcing A company to withdraw at around 3:45. Yet K Company closer to the beach held enormous firepower in the form of Sherman tanks that obliterated 12 bunkers rather quickly.  In the words of Company K’s commander: “I was given three tanks (the other two were out of action, one with engine trouble and one with a jammed breech of its 75) to accomplish this mission. I put one squad of the Second Platoon behind each tank and deployed the Third Platoon to set up a skirmish line behind the tanks. We encountered twelve huge bunkers with a minimum of twenty Japs in each. The tanks would fire point blank into the bunkers, if the Japs stayed in the bunkers they were annihilated, if they escaped out the back entrance (actually the front as they were built to defend the beach) the infantry would swarm over the bunker and kill them with rifle fire and grenades. By the time we had knocked out twelve bunkers the Second Platoon . . . were out of ammunition and had been replaced by the Third Platoon and they too were out or down to a clip of ammunition per man. I called a halt and sent for the First Platoon. By the time the First Platoon arrived and ammunition was resupplied forty-five minutes had elapsed. We continued the attack and found two more bunkers but the enemy had in the meantime escaped.” The immense power of the tanks forced the defenders to retreat. 

 

During this action the 1st marines suffered 17 deaths and 52 wounded and claimed to have counted 300 Japanese corpses. The capture of Hell’s Point enabled the Americans to establish a position at Blue Beach to reduce the distance for supplies. General Rupertus command post was also moved there by Deemer 28th. The next day the American advance was delayed until the arrival of Colonel John Seldens 5th marines. General Rupertus feared he might be outnumbered at the airdrome so he played it safe. During the fighting at Hell's Point, a curious misadventure befell Corporal Shigeto Kashida of the 1st Machine Gun Company. The trench in which he was defending suddenly caved in, burying him helpless up to the neck. An astonished Marine, observing Shigeto's apparently disembodied head blinking at him, paused to debate whether to shoot or shovel, which dilemma was resolved by the arrival of an intelligence officer who ordered the corporal disinterred and made prisoner. Shigeto painted a depressing picture of his battalion's situation, but he mentioned the original plan for the 2nd Battalion was to reinforce the 1st, something that might still be accomplished; he also mentioned the presence somewhere in the vicinity of the 141st and 142d Regiments, possibly within striking distance. Since Colonel Sumiya had conducted withdrawals following every action to date, it could be presumed that a good part of his force remained intact. Thus Rupertus was right in his belief the Japanese may have large numbers at the airdrome.

 

The 1st Battalion under Major William H. Barba and the 2nd Battalion under Lieutenant-Colonel Lewis W. Walt got aboard 9 APD’s at Cape Sudest and arrived off Cape Gloucester during the morning. However during the transit, there was a large storm that caused some confusion, leading some elements to land at Yellow 2 and others at Beach Blue. General Rupertus planned for the 1st Marines to continue their advance along the coastal road while the 5th Marines would perform a wide sweep on the left flank to attack airstrip No.2. At 3pm following the artillery and aerial bombardment, the Marines launched a fierce offensive. The 2nd battalion, 5th marines attacked simultaneously with the 1st Marines along the coast road and both ground immediately inland. Major William H. Barba's 1st Battalion was just struggling out of the swamp and jungle near the line of departure. The unexpected terrain difficulties, however, kept the plan from being carried out. Both battalions sent out patrols in an effort to establish contact, but a combination of darkness and unfamiliar territory prevented positive results. 

Supported by tanks, artillery, mortars and rocket launchers, Whaling’s 1st Battalion successfully reached the eastern end of Strip No. 2 at 5:55 and immediately commenced setting up a defensive perimeter. The 3rd battalion followed behind and extended the perimeter to the left, with Selden’s 2nd battalion arriving at 7:25pm extending the perimeter around airstrip No 1 towards the beach. It seemed Colonel Sumiya realized the futility of attempting a defense upon the open ground against American armor, so he pulled his units away towards Razorback Hill from which they could launch harassment maneuvers against the new American perimeter. The Japanese had begun firing artillery and mortars into the airdrome. The Marines, somewhat astonished by such goings-on, called for mortar and artillery support of their own. They reported that, according to their best estimates, the enemy had reoccupied the defenses in at least full company strength. 

The marines were formulating a plan to deal with the menace and the Japanese took advantage of the lull time to launch a banzai charge that failed to gain any ground. The Japanese continued their harassment, until the Marines received some tank support to launch an offensive. Platoons from different units got together to perform a sweeping maneuver, advancing 300 yards from the defensive line. They ran into bunkers, foxholes and trenches manned by Japanese. The marines mopped them up with grenades and automatic weapons, then at 11:30 suddenly all the fighting ceased. No more enemy seemed to remain near the front. The marines had suffered 13 deaths and 19 wounded, but counted 150 dead Japanese. With more tanks on hand, the Marines gradually pushed the Japanese to flee back towards Razorback Hill.

Meanwhile, because of the repeated attacks, Colonel Masters men had been patrolling, trying to pinpoint where the Japanese were concentrated. At 1:55am on December 30th, the 3rd and 4th companies of the 54th regiment had discovered an excellent approach towards the Marine perimeter. As was always the favored Japanese strategy, to concentrate force against a narrow sector, they chose to attack at this place called Coffin Corner, a natural causeway connected to ridges. The two companies attacked under the cover of a storm. The Japanese unleashed mortars and machine gun fire and quickly overran a machine gun position, but G company launched a counter attack pushing them back. The battle raged for nearly 5 hours, but by 7am it ceased. The marines had 6 deaths, 17 wounded and would count 89 Japanese dead with another 5 captured. Yet that concludes the action in Cape Gloucester for today, for now we need to jump back to New Guinea.

Back on December 8th, General Nakai commenced an offensive against Kesawai, dispatching the Saito Volunteer unit for the task. The unit had the aid of native guides who gave them detailed information on the terrain, allowing the Japanese to infiltrate behind a forward Papuan platoon led by Lt C.E Bishop. They explode all of their booby-traps, allowing the 1st battalion, 78th regiment to advance behind them into Kesawai 2 without much difficult, annihilating the Papuan platoon and securing the eastern portion of the highland. Meanwhile the 3rd battalion crossed the Boku River and captured Koropa, cutting off the commandos at Isaria; the 2nd battalion, 239th regiment crossed the Boku river and assaulted the commando position at Ketoba, but the Australians resisted until nightfall before withdrawing towards Isariba. Nakai’s enveloping maneuver was a success, forcing the commandos and Papuans to withdraw towards the Evapia River.

On December 9th, Brigadier Eather ordered A and C companies of the 2/25th battalion to advance forward as the commands pulled back towards the Mene River. Meanwhile at 7:15am at Isariba, the Japanese had begun a series of attacks. The attacks were repelled with vicker guns, grenades and a quick air strike from 20 Kittyhawks and Boomerangs that bombed and strafed the attackers. The 2/25th companies arrived at Evapia and one of their patrols managed to ambush several Japanese parties over the next few days. On December 12th, Nakai arrived at Kesawai where he ordered his 1st and 3rd battalions, 78th regiment to attack the 2/25th positions by nightfall. C Company's machine gun fire managed to halt the enemy assault from the north, but another came from the south. A Company found itself surrounded as the Japanese managed to get between the two Australian companies, firing their Woodpeckers from multiple directions. It was a 5 hour battle until the Australians repelled the enemy who gradually pulled back west.

At 5am on the 13th, the Australians were running low on ammunition and were forced to withdraw. The 2/25th advanced through think jungle and deep swamps, by 8am they had managed to get to safety after suffering 5 deaths and 14 wounded but killing an estimated 67 Japanese. The companies withdrew east of the Evapia River, rejoining the rest of their battalion. Nakai expected his enemy was attempting an offensive against Madang and ordered his men to return to their former defensive positions, leaving token garrisons at Koropa and Kesawai. Because of the heated attacked, General Vasey worried it was preliminary to something much bigger, so he ordered the 2/16th battalion to perform punitive attack along Shaggy Ridge and Eather’s 2/33rd battalion would retake Kesawai.

The 2/33rd Battalion advanced under the cover of darkness to the 5800 Feature to attack any Japanese there, and to move the Papuans across the Evapia to establish a patrol base for the Koben-Koropa-Solu River area . With three of his companies Colonel Cotton of the 2/33rd moved off an hour and a half after midnight on the 18th-19th December towards the summit of the 5800 Feature arriving just before dawn . At 2.10 p.m. a section made contact with the enemy about 700 yards south of the highest pinnacle on 5800. The patrol withdrew while the artillery fired 120 rounds. By 5 p.m. the enemy had had enough and withdrew enabling one company to occupy the pinnacle . Next day the battalion patrolled the whole area and found evidence of Japanese occupation and a hasty withdrawal.

The allies finally unleashed operation backhander, the amphibious assault of Cape Gloucester. The 1st Marines had a long rest after Guadalcanal and would now be the spearhead to reconquer New Britain. However the Japanese were not going to just roll over easily.

 

- 109 - Pacific War - Drive on Sio , December 19-26, 1943

Last time we spoke about landings against Arawe, the continuation of the Bougainville campaign and some new action in the CBI theater. Despite a rubber boat disaster, the operation against Arawe went off successfully seeing another allied landing taking the Japanese by surprise. Now the Japanese would be forced yet again to launch a counter attack hoping to dislodge the allied forces from a new beachhead. Over on Bougainville the Marines performed some assaults against hills such as Hellzapoppin ridge to expand the perimeter enough so the Army boys would have an easier time of taking over. Over in the CBI theater, the onion man Wingate was given the task of expanding his chindits and the Americans wanted their very own chindit force. Stilwell decided the time was ripe to unleash a minor offensive in Burma and soon saw what looked like a weakened Japanese perimeter was in fact very strong.

Last time we saw General Cunningham’s men successfully landing at Arawe where they hoped to build a new PT boat base. Troop A was supposed to land an hour before the main landing to cut the coastal road near Umtingalu village and Troop B would land at Pilelo island to cover the main passage to the harbor. Troop A was a disaster. Their 15 rubber boats were met with 25 mm dual purpose guns that sank 12 boats, killed 12 men and wounded another 70. Troop B was more successful landing on Pilelo and capturing the radio station before engaging in a fire fight. For the main landing at House FIreman Beach, there was little resistance. Sporadic machine gun fire was silenced by rockets as the men landed. The Japanese tossed some air strikes to hit further landings and convoys, but allied CAP managed to limit the damage. 

A few days after the landing, the Komori Detachment reached the village of Didmop along the Pulie River where they paused to reorganize and rally the incoming survivors fleeing the landing area. The difficult terrain and river crossings prevented Komori and his men from assembling into offensive positions until December 25th. Meanwhile back on the 18th, the 1st battalion, 141st regiment began an advance from the Itni region aboard 7 barges. Unfortunately for them, two LCVP’s bearing 19 men on patrol had been sent by Cunningham to Cape Peiho. The two forces ran into another and after an exchange of gunfire the US soldiers abandoned their LCVP’s and retreated back along the Arawe coast. Another patrol traveling by LCVP was also fired upon by Japanese barges near Umtingalu that same day, but was able to return to Cape Merkus.

On Christmas night, 100 men of the Komori detachment assaulted the main line of defense across the neck of the peninsula. The inexperienced American cavalrymen of the 112th managed to repel, albeit with some difficulty. The attack prompted General Cunningham to believe Komori was in charge of the lead element of a much larger force, most likely enroute from Gasmata. He therefore requested reinforcements and General Krueger responded by dispatching a company of the 158th infantry by PT Boats. Meanwhile the lack of results from the attack prompted Komori to defer further attacks until the arrival of Major Tobuse’s battalion. On the 27th, allied intelligence indicated the Japanese had retaken Meselia and Umtingalu, prompting Cunningham to withdraw all outposts and patrols within the main line of defense. The 2nd battalion, 158th regiment were sent to reinforce the beachhead while Komori and Tobuse finally made contact with another. The first order of business to contain the growing American perimeter. Both commanders believed the Americans sought to repair the unserviceable Lupin Aerodrome.

700 yards from the US line the Japanese established a series of alternate positions taking advantage of the terrain and concealment making it difficult to spot. Cunningham would remark "This is not an organized position in the accepted sense of the word, it consists apparently of shallow trenches and deep fox holes… The ground is covered with a thick green mat about 12 to 18 inches in depth which makes observation absolutely impossible… Officers and men… report that they have not seen a single Japanese and that they are unable to locate machine guns firing on them from a distance of 10 to 20 yards.” From these positions the Japanese harassed the Americans using mortar and automatic weapons fire. Whenever the Americans tried to pinpoint where the fire was coming from the Japanese would simply switch positions to another. Within these parameters only limited skirmishing was carried out for the next few days. 

On January 4th, Komori reported repulsing a strong American and two days later received his first citation from Emperor Hirohito for his heroic achievement. Meanwhile a much frustrated Cunningham began sending reports to Krueger he could not spot the enemy and was convinced continued attacks would simply result in further casualties. By January the 9th he reported 75 dead, 57 wounded and 14 missing. He requested Kreuger send him some tanks and on the 9th he received the 1st marine division's 1st tank battalion from Finschhafen. The 1st Tank Battalion had been left behind at Finschhafen because of transportation shortage and limited range for tank operations in the inhospitable terrain of the Cape Gloucester region. Eventually Rupertus would also release the rest of the tank company then in reserve at Cape Gloucester to help out.

The Marine tanks and Army infantry quickly worked out the details of how they would go about combined operations. The morning of January 16th kicked off with a squadron of B-24’s followed by another of B-25s bombing the Japanese positions. This was followed up by artillery and mortars and then two 5 tank platoons began their assault against a 500 yard front. Behind the tanks were infantry of the 158th and despite the swampy terrain and thick vegetation, the tank-infantry stormed forward. The Japanese resisted ferociously, grounding two tanks that had to be destroyed lest the Japanese seize them later. The Americans destroyed the enemy’s positions, crushing numerous automatic weapons and a 75mm mountain gun. But the Americans had no orders to hold any positions, so they destroyed and pulled back to their perimeter for the night.

The following morning the Americans resumed the attacks with flamethrowers eliminating small pockets of resistance still remaining. Komori still obsessed with defending Lupin aerodrome to the last man ordered a withdrawal, but not before radioing to the brigade HQ "fight till the glorious end to defend the airfield" which earned him a second Imperial citation on February 7. During these actions the Americans suffered 20 dead, 40 wounded and two tanks. For Komori’s men they had 116 dead and 117 wounded. For the next 3 weeks the fighting would deteriorate into a matter of patrol skirmishes, with Komori triumphantly reported back to HQ how the airfield was still in Japanese hands. The reality however was the Japanese were heavily outnumbered and lost control of the air and sea. How many men Komori commanded remains difficult to figure out as no documents were captured after the operation. It appears unlikely there were more than 1000 under his command. Early in the operation the Japanese were supplied by airdrop, often during daylight in view of the Americans. Yet as the Americans tightened their grip over the sea and air more, Komori became increasingly dependent on the trickle of supplies coming over the tortuous trail from Iboki. Carrying and distributing these supplies imposed still more of a drain on his manpower, and he withdrew his headquarters to Didmop to give more attention to this phase, leaving direct defense of the airfield to Major Tobuse. Yet that is all for Arawe for today, because we need to travel back over to New Guinea.

Wareo had fallen and now the Australians were advancing upon Fortification Point as General Katagiri’s 20th division were retreating towards the northern coast. The 20th division would arrive at Zagaheme and Orarako on the 22nd and 25th respectively. With these movements occurring the Australians now felt the time was ripe to launch an offensive against Sio. On December 20th, General Wootten ordered the 20th brigade to advance through the 4th brigade's positions and begin a rapid pursuit towards Sio. The next day, Brigadier Windeyer had his men advance towards Wandokai while Wootten was reorganizing his forces to allow the coastal advance to continue. Meanwhile the 24th brigade took over the Gusika-Wario-Sattelberg area; the 4th brigade took over the Fortification Point-Masaweng River area; the 26th brigade advance down the coast and would be ferried to the mouth of the Masaweng to support Windeyer’s advance.

The Australians enjoyed the advantage of aerial support in the form of Bostons, Mitchells, Marauders, Airacobras and Thunderbolts who continuously hammered the Japanese with bombs and strafing runs. Alongside this allied PT boats harassed the Japanese barge fleet, between the 9th and 13th they would sink 23 barges along the coast, mostly south of Sio. Despite the air and sea support the overland advances were particularly rough on the men. From fortification point to Kapugara gorge the coastal track ran along a flat kunai ledge some hundred yards wide, between the sea on each side with sharp coral terraces. They had little cover along the line of the advance. There were also few natives inhabiting the area. The men of the 20th brigade were not in great condition when they began the pursuit. They were stricken with malaria and Colonel Simpson anticipated the enemy might hit their left flank so he dispatched two companies to travel parallel with the main coastal advance and those guys had some even rougher terrain to travel. There was little water to be had along the coast and the long kunai fields increased the heat exponentially. The men occupied Hubika on the 22nd without opposition. The allied engineers would find the gorge beyond Hubika would prevent any progress by the tanks, so the troops would have to proceed without their support. By nightfall the 2/13th battalion would advance another 3000 yards facing no opposition. They got around 1500 yards past Wandokai when suddenly mortar and artillery fire rained down upon them. This was Captain Yoshikawa’s 1st battalion, 80th regiment who unleashed a bombardment for 2 hours upon the advancing Australians. Though it appeared like there was a major fight on their hands, it was only rearguard actions. Yoshikawa and his men were retreating towards Ago that night. 

Christmas would see Windeyer receive the gift of further artillery reinforcements for his advance. The 62nd battery and 2/12th field regiment came over and on Boxing day Colonel Miyake would decide to abandon Ago and continue the retreat towards Kanomi. On the night of the 26th a company from a boat battalion of the 592nd EBSR, alongside an Australian radar detachment landed on Long Island. This was Operation Sanatogen, the mission was to set up a radar station and observation post on Long Island to help with the landing at Saidor and thwart Japanese barge movements. The Japanese had never placed a garrison on Long Island, but it was used as a staging point for barges moving between Rabaul and Wewak. 

At 9am on the 27th, 18 Mitchells and 12 Bostons bombed and strafed the Walingai and Kanomi areas before Windeyers resumed his advance. The 2/13th advanced through Ago and occupied Walingai unopposed by the end of the day. The next day saw Australian patrols running into Japanese positions around Kanomi. At 11:15am a patrol of the 2/13th was fording a creek when they were fired upon. The patrol saw at least 14 Japanese retreating north around Blucher Point as they fired vicker guns and mortars upon them. During the afternoon the allied began a heavy artillery bombardment. The speed at which the Australians were advancing was providing results as the Japanese were forced to further withdraw towards Kalasa. Yet the Australians were stretching their logistical lines forcing Wootten to halt the forward units for 2 days.

The two day delay allowed General Katagiri to get his men past Kalasa and reach Sio without any hindrance. On new years eve the 2/15th resumed their advance finding slight resistance around Nanda. At 5:30pm the 2/15th were fired upon by a few bands of Japanese and responded with artillery fire forcing them away. To avoid unnecessary casualties the Australians halted at the last creek before Nanda and resumed the march on new years day. The 2/15th then passed through Kwamkwam and captured Sialum Island during the afternoon of the 2nd. Sialum lies around half way between Fortification Point and Sio and it afforded the Australians a decent area to build a large supply dump on its sheltered. Yet the advance to Sio was not the only one going on, on New Guinea.

 

Since the battle of John’s Koll and Trevor’s Ridge, General Nakai’s detachment were forced to withdraw farther back into the hills. The Nakai detachment were now clinging to Shaggy Ridge the Kankirei Saddle and the area between the Faria River, Madang and Bogadjim.

At Kankirei, Nakai dispatched Captain Ohata Masahiko’s 3rd Company of the 1st Battalion, 26th Field Artillery Regiment. General Nakai told Ohata that ‘the enemy is extremely sensitive to the use of artillery fire arms so that the artillerymen are expected to cooperate closely with the infantry men until the very end”.Ohata recalled “I realized what was expected from our commander, and he also said please take good care of your life. It took more than twenty years to train one artillery officer, but a gun is only material. We can replace the gun, but not an artilleryman.’ There is a very reasonable explanation for Nakai’s order. The IJA artillery field manual indicated their field guns were more valuable than artillerymen. In article 10 it said ‘The gun is the life of the Artillery. Therefore, the Artilleryman must live and die with the gun, and share the honor and shame together with the guns. One must continue to fight until the end’. Nakai at this time prohibited suicide and it seems was trying to save the lives of his artillerymen, lest they die for the sake of their guns.

The main Japanese position was at Shaggy Ridge, a 4 mile long spur dotted by several rocky outcrops where the Japanese troops established numerous strong points. From the Pimple, a large rocky peak rising around half way along the crest of Shaggy ridge, the Japanese found it extremely sturdy to defend. The feature often saw a mist envelope it adding to its defensive capabilities. 

As the Japanese clung to their heights, the Australians were busy developing their new main base at Dumpu. Airstrips, roads, bridge, culverts and numerous buildings were being worked on and with the recent acquisition of the Ramu valley they were also building a forward air base at Gusap. The only major offensive against Shaggy Ridge came in late October.  In accordance with Vasey's advice, Brigadier Dougherty prepared to attack the southernmost peak of Shaggy Ridge on the 20th. For three days from the 17th Dougherty’s patrols crept as near as they could, and early on the 20th, Captain Whyte the F.O.O. of the 54th Battery, directed the fire of his guns on to the Japanese position.  At midday forward units reported that they were within five yards of a four-strand barbed-wire fence; the Japanese position on a kunai covered Pinnacle was about 30 yards away. Between the enemy position and his men, there was a steep gully about 100 feet deep with precipitous slopes on both flanks . The Japanese hand cut fire lanes through the kunai and were dug in and heavily bunkered from the cliff face. Through the clever use of artillery fire, the Australians tricked the Japanese into retiring temporarily to gain shelter. The artillerymen varied the rate of fire so it was never the same, while platoons stormed specific ridges, gaining ground without casualties.To defend his western flank, General Vasey dispatched  the 2/7th to Kesawai 1 and the 2/6th to Kesawai 2.

Yet the role of the 7th division for the time being was really limited to patrol activities. On 23rd October a section of the 2/2nd Commando Squadron led by Lieutenant Doig crossed the Ramu and moved up the Urigina Track next day, seeking a way east to the Mataloi-Orgoruna area. Lt Doig entered this new territory on the 25th and by 9 a.m. trees across the track near Orgoruna suggested that the Japanese might be in possession. Between 25th and 31st October Captain Haydon's company of the 2/25th Battalion tried to reach the Japanese track between Paipa and Kankirei. After moving up the Evapia River and then through rugged unmapped country for 4 days the patrol leader was forced to return as he realized that it would be impossible for him to reach his objective without further rations. On the 29th the 2/7th Commando Squadron, an engineer, Captain Gossip of the 2/6th Field Company, and two others left to patrol a road from the Ramu Valley across the Finisterre Ranges towards the Japanese road. This patrol returned on 1st November reporting that there was no possibility of making a road from the Kesawai area towards the Japanese roadhead. 

Lieutenant Maxwell of the 2/6th Commando Squadron, performed a three-day reconnaissance towards Yokopi , walked right into an enemy defensive position on the first day out, saw five Japanese looking at him from about 20 yards away, and retired before they could fire at him.  Sergeant Berrell of the Papuan Battalion led his section, three men from the 21st Brigade, and 50 native carriers on a 13 days' patrol into the ranges to patrol enemy movement in the Kankirei area. He returned on 11th November without having found a worthwhile observation post near Kankirei. On the 20th October MacAdie sent a patrol from the 2/2nd Squadron to Josephstaal to find out whether the Japanese were there, and whether a strip could be constructed. Accompanied by Sergeant-Major England of Angau, Lieutenant Green's small patrol of five troopers, 32 native carriers and five police boys left for Sepu where it remained until setting out on the main journey on 3rd November. The route chosen by Green and England did not follow the known native tracks as the Australians wished to avoid any contact with Japanese patrols. The journey would take nine days. Over at Atemble, where the Japanese were known to be in some strength, was bypassed and, although there were tracks of Japanese horsemen at Sambanga and reports from natives that the Japanese did occasionally patrol the area between Atemble and Josephstaal and Madang, there were no encounters. On 13th November Green arrived at Josephstaal, which was not occupied and which had only been visited occasionally by small enemy patrols in recent months. The patrol returned to base on 26th November. 

 

On December 2nd a patrol of 42 men from the 2/33rd Battalion led by Lieutenant Scotts set out, urged on by Eather's hope that it would be able to blaze a track into the heart of the Japanese defenses at Kankirei from the west and get a prisoner. Moving up the Mene River Valley and across the 5500 Feature, Scott established a base on a steep ridge. The next day he moved down a spur to some native huts where the dense jungle was replaced by kunai and then crossed into another spur, where they established an observation post. Meanwhile a patrol from the 2/2nd Pioneer Battalion was attempting to observe the Kankirei Saddle area from the east. On the 7th Lieutenant White led out eight Pioneers, two Angau warrant-officers and 20 natives from Bob's Post following the Japanese Mule Track north to Toms' Post. Next day the patrol moved on along a well-surveyed track, and, about 1,500 yards beyond Toms' Post, saw a strong enemy position ahead on a high feature astride the track. On the 9th and the morning of the 10th White tried to work round to the north of the enemy position to carry out his original task, but dwindling rations, heavy rain, and rugged country forced his return to the track. Accompanied by two men White then advanced along the track but after 20 minutes he came under heavy fire. The three men ran back down the hill which they had been climbing but White was hit by machine-gun fire and fell.

All of these patrol actions helped prevent the Japanese from penetrating south and figured out generally where the Japanese were in numbers. On November 9th Vasey relieved the 21st brigade at the front with the 25th brigade. Along with this the 2/6th commando squadron and a Papuan company were sent to reinforce the front while the 2/7th command squadron was withdrawn. And with that, after nearly 10 months since Lt Rooke and his platoon of the 2/7th battalion had arrived on the airstrip at Bena, the Bena Force ceased to exist. They had 12 deaths, 16 wounded and 5 men missing but claimed to have killed over 230 Japanese. They helped build the Garoka airfield; over 78 miles of motor transport road between Bena and Garoka, Sigoiya, Asaloka and Kainantu and produced maps of completely unknown areas In his final report MacAdie wrote: “The force fulfilled its task. Every enemy patrol which crossed the Ramu River was driven back with casualties, and very determined enemy attacks were repulsed with heavy casualties. In addition the enemy lost many men in ambushes on tracks north of the Ramu River... There is no doubt that the enemy regarded this force as a menace to his flank, and little doubt that the size of the force was grossly overestimated.”

Now the 2/2nd Commando Squadron would assume the responsibility for the defense of the Bena-Garoka area. November would see the start of an intense hide and seek artillery duel. The Australian artillery was attempting to neutralize the Japanese 75mm guns. Captain Ohata’s had placed two gun emplacements on the outskirts of Shaggy ridge in a position that protected the ridgeline in the front. The first emplacement were not entirely concealed and thus quickly became a target. Fortunately the guns survived as the Australian fire hit their shields mostly. Captain Ohata thought he could conceal their muzzle flashes by firing lower. The second gun emplacement was completely covered by shelter yet Ohata would remark ‘However the footsteps of the soldiers who were coming in from the behind the position were spotted by the search airplane. We were indeed astonished by their way of finding the gun position.’ By the end of November General Nakai was preparing to hit Kesawai and counterattack towards Dumpu. In early December patrols from the 2/16th were probing Shaggy Ridge. Vasey intended to perform a diversion to attract the Japanese attention away from other pending operations in New Guinea and New Britain. An idea was floated around to have Brigadier Dougherty raid Kankirei, but that's it for New Guinea as major events were unfolding for the CBI theater.

Over in Tokyo, on November 5th and 6th the Greater East Asia Conference was being held. Attendees included Hideki Tojo for Japan, Zhang Jinghui for Manchukuo, Wang Jingwei for the Republic of China based in Nanjing, Ba Maw for Burma, Subhas Chandra Bose for Free India, Jose P Laurel for the Philippines and Wan Waithayakon for Thailand. Notable exclusions would be that of Korea and Taiwan, whom the Japanese had annexed and did not want to give any political autonomy to. There was also Vietnam and Cambodia who were not invited so as to not offend the Vichy French government who was still claiming French Indochina to be under their rule. There was also Malaya and the Dutch East Indies, but Japan figured they would be simply annexing these regions as their natural resources were now the lifeblood of the empire. Of the attendee’s, Suhas Chandra Bose was only present as an observer as India was still a British colony and the representative of Thailand under strict orders from Plaek Phibunsongkhram was to emphasize on every possible occasion that Thailand was not under Japanese domination, but in fact an allied nation. You might be asking why did Plaek Phibunsongkhram not attend such a grand event himself, well he actually feared if he were to leave Bangkok he would be ousted. 

Hideki Tojo made a grand speech, greeting each of the participants and praising the spiritual essence of Asia in opposition to the materialistic civilization of the west. To give you a taste of this meeting here are some of the dialogue amongst participants.

Tōjō Hideki stated in his speech: "It is an incontrovertible fact that the nations of Greater East Asia are bound in every respect by ties of an inseparable relationship".

Ba Maw of Burma stated: "My Asian blood has always called out to other Asians… This is not the time to think with other minds, this is the time to think with our blood, and this thinking has brought me from Burma to Japan."

Jose Laurel of the Philippines in his speech claimed that "the time has come for the Filipinos to disregard Anglo-Saxon civilization and its enervating influence… and to recapture their charm and original virtues as an Oriental people."

Subhas Chandra Bose of India declared: "If our Allies were to go down, there will be no hope for India to be free for at least 100 years".

 

Overall the meeting was characterized by praise of solidarity and condemnation of western imperialism, but in terms of how Asia was going to come together and economic development and such, there really was no meat to any of it. Tojo simply kept reiterating how great Pan-Asianism was against the evils of the white devils. Yet for all the talk of asian unity, the Japanese governments actions were anything but that. The Japanese viewed themselves as racially superior to that of the other asian nations. They saw themselves as the Great Yamato Race and that they were destined to rule over the other asian peoples, similar to a father and son relationship. To actually go off the script so to say, I happen to have covered this topic extremely thoroughly in a 4 part series I did on my patreon about General Ishiwara Kanji. You see, Hideki Tojo’s main military/political rival was Ishiwara Kanji, and all of the greater east asian stuff was literally stolen from Ishiwara.

 

Ishiwara, for those unfamiliar, is someone I believe had an unprecedented impact on global history. Ishiwara pretty much single handedly began WW2 I would argue. He was a very bizarre figure who came to the realization after WW1 that the entire world would be engulfed in what he called “the final war”. To prepare Japan against this apocalypse he believed Japan had to seize Manchuria for her resources, to empower the empire so it could face the United States. He also believed it was absolutely necessary to ally with China and that everything needed to be done to create a harmony between the two peoples. Ironically after Ishiwara caused the invasion of Manchuria, it all in his view got out of hand and he was tossed aside by people like Tojo. He spent the entire war openly criticizing Tojo and the policies of Japan while trying to create this Pan-Asian league, and Tojo simply copied what he was doing, gave it a different name and made sure to eliminate the elements about allying with China and stopping the war with her. Ishiwara is a fascinating figure and to be honest I was so happy with the 4 part series I told on my patreon I might be releasing it on my Youtube channel and on my personal podcast server soon.

 

Now back to the conference, in the words of Indian Historian Panjaj Mishara  “the Japanese had revealed how deep the roots of anti-Westernism went and how quickly Asians could seize power from their European tormentors”. Tokyo hoped that a major demonstration of Pan-Asianism would lead China to broker peace with Japan and thus join them in a war against the west. A major theme of the conference was that Chiang Kai-Shek was not a proper asian and that no Asian would ally themselves to the white devils. As you can imagine the speeches made by Tojo emphasized how evil Britain and the United states were, yet at the same time praised Nazi Germany. Here are parts of Tojo’s speech.

 

“The need of upholding international justice and of guaranteeing world peace is habitually stressed by America and Britain. They mean thereby no more and no less than the preservation of a world order of their own, based upon division and conflict in Europe and upon the perpetuation of their colonial exploitation of Asia. They sought to realize their inordinate ambition in Asia through political aggression and economic exploitation; they brought on conflict among the various peoples; they tried to destroy their racial integrity under the fair name of education and culture. Thus, they have to this day threatened constantly the existence of the nations and people of Asia, disturbed their stability, and suppressed their natural and proper development. It is because of their notion to regard East Asia as a colony that they harp upon the principles of the open door and equal opportunity simply as a convenient means of pursuing their sinister designs of aggression. While constantly keeping their own territories closed to us, the peoples of Asia, thus denying us the equality of opportunities and impeding our trade, they sought solely their own prosperity. The Anglo-American ambition of world hegemony is indeed a scourge of mankind and the root of the world’s evils.”

 

“As regards the situation in Europe, we are very glad that our ally, Germany, has still further solidified her national unity and, with conviction in modern times.

As regards the situation in Europe, we are very glad that our ally, Germany, has still further solidified her national unity and, with conviction in sure victory, is advancing to crush the United States and Britain and to construct a new Europe.

The War of Greater East Asia is truly a war to destroy evil and to make justice manifest. Ours is a righteous cause. Justice knows no enemy and we are fully convinced greater of our ultimate victory.”

 

Meanwhile the allies held the Sextant Conference in Cairo between November 22-26th. This conference established China’s status as one of the four world powers, kind of a cheeky jab at Japan and a means to sway Chiang Kai-Shek from surrendering. At the conference plans were made for an offensive in Burma codenamed Operation Champion with sub operations Tarzan and Buccaneer. Lord Mountbatten presented  three plans of action. First Operation Tarzan called for 4 Indian divisions of the British 14th army group's 15th army  to concentrate their forces in Chittagong and cross the Maungdaw-Buthidaung line in mid-January. The next year they would capture the Burmese coast in order to defend Chittagong and occupy Sittwe on the Burmese coast. Then three divisions of the 4th Army, would assemble at Imphal and move east with the objective of destroying Japanese lines of communication and advancing to Arak and various parts of Sidon in northern Burma. In March, the Chindits long-range infiltration force would be parachuted into Burma, behind the Japanese lines while the Chinese Expeditionary Force (CEF) in India would cross the Ho Kang Valley and advance eastward into Myitkyina. The Chindit special forces would then support the Chinese forces and occupy Bhamo in April, while the Yunnan Army would begin operations on March 15 and advance to Lashio in April to join the British forces at Lashio and Bhamo. In the Bay of Bengal, a massive amphibious offensive would also be launched, with 3,000 British and American long-range infiltration troops participating.

 

Operation Musket would see the capture of Cape Sumatra and Operation Buccaneer was to be an amphibious operation to seize the Andaman Islands in order to cut off the Japanese supply lines. Chiang kai-shek expressed support for Tarzan, but once again insisted for it to be coupled with a massive naval operation in the Bay of Bengal. Though the British were reluctant to do this, US pressure eventually convinced them to land on the Andamans. The Chiefs of Staff then agreed to drive Japan out of Burma and reopen land links with China, with Stilwell conducting the ground attack in the north and Mountbatten commanding the amphibious landings in the south.

 

 The American delegation told Chiang kai-shek that for the following six months, only 8900 tons of supplies could be flown to China via the Hump route each month, even though Chiang continuously pushed for 10000 tons. In the end, President Roosevelt promised to increase the airlift supply to China to 12000 tons, and also promised that B-29 Superfortress bombers would bomb Japan from Chinese bases. By the way if you are interested in the beginnings of the bombing campaigns against the Japanese home islands, please check out the podcast I did with Dave from the cold war channel over on my youtube channel. It is actually B-29’s operating in India and China that kicked it all off, and its not often talked about. 

 

Many of the resolutions and promises, would not be really implemented. Politically, many arrangements were also made for the postwar international situation. Roosevelt and Churchill supported the territorial claims of the Republic of China, such as returning Taiwan and Manchuria to the Republic of China and deciding to allow Korea to become independent "in due course". The Cairo Declaration, however, made no specific mention of the future of the Ryukyu Islands. China of course wanted them, but the US believed that the Ryukyu Islands could be left to Japan after the war if they were completely demilitarized. It was also agreed between China and the US that Lushun would be used as a public military port for the Americans after the war, and that Dalian would become a free port. Roosevelt also consulted Chiang kai-shek on the possibility of the abolition of the Japanese imperial system along with the emperor, Hirohito, but Chiang kai-shek mentioned that the cause of the war was the Japanese warlords, and that the issue could be left to the Japanese people to decide for themselves after the war. The Americans did not want France to return to Indochina and offered Chiang kai-shek control of French Indochina; but he publicly declined, as Chiang kai-shek strongly advocated the independence of Korea and wanted to assist in the independence of Vietnam. Roosevelt firmly supported Chiang kai-sheks efforts to end imperialism in East Asia. To end the conference off, on December 1, the Allies issued the Cairo Declaration, demanding Japan's unconditional surrender and the return of all occupied lands.

And so the drive to Sio was raging on, the Japanese were not being given a moment to breathe as they continued their withdrawal further north. Back over in Japan, Tojo was trying to win over China, but the allies were making sure to keep Chiang Kai-shek firmly in the fold in a 4d game of global chess.
