The Pacific War - week by week

- 88 - Pacific War - The Mysterious Battle of the Pips, July 25 - 1 August, 1943

Last time we spoke about the allied drive to Munda and General Sasaki’s major counter offensive. General Wing began the drive upon Munda Point, but General Sasaki predicted many of the routes the Americans would take and ordered his forces to create tedious roadblocks and defensive positions to foil their advances. The allied progress was brutally slow, despite having the enormous advantage in artillery, naval and aerial bombardment support. The Japanese pillboxes were proving to be devastating to the allied infantry, requiring tanks to be brought over to New Georgia. When things began to halt, suddenly General Sasaki performed a counter offensive seeing a daring attack directed at the headquarters of the 43rd division. The attack nearly broke the lines of communications, but luckily the Fijian commandos outperformed the japanese at their own game of night fighting. Lastly the IJN suffered terrible losses to allied aircraft collapsing their reinforcement efforts.

The battles in New Guinea and New Georgia were particularly bloody, in all honesty things had begun to really escalate when you look at it from a numerical point of view. Over on Green Hell, General Savige had just seized Mubo, the Pimple, Green Hill and Observation hill taking them out of Japanese hands. The Japanese had withdrawn to Komiatum while simultaneously trying to defend the Bobdubi ridge area against Brigadier Hammer’s 15th brigade. General Savige, still unaware Salamaua was not the main target and in fact was being used as a deception to cover for Lae, continued his offensive, hoping to drive the enemy north of the Francisco River.

Over on the other side, General Nakano’s 1st battalion of the 80th regiment had managed to  push Companies B and A off their ambush position on the Bench Cut Track. They were forced to withdraw towards Gwaibolom by July 10th. Meanwhile to the south Major Warfe launched an attack along Goodview junction. Captain Wally Meares of C platoon marched up Stephens Track while Captain John Winterflood’s B platoon took Walpoles track. Lt Hugh Egan created a blocking position using just 7 men around 800 meters south of Goodview Junction. The platoons went to work advancing down the steep ridges dislodging Japanese from outposts. Captain Meares platoon were continuing along the Stephens track when they suddenly encountered strong resistance from some Japanese who took a position along the Tambu Saddle which is at a junction between Stephens track and the Mule track. After engaging the Japanese, the platoon was forced to bypass them moving along the Mule track towards the Komiatum track where they ran into more Japanese. Meares men killed 13 Japanese on the Mule track before deciding to withdraw back to the Stephens track and dug in.

The Japanese had surprised Warfe’s men. The forces they were running into were mainly the 1st and 2nd companies of the 66th battalion along with Araki’s HQ staff who had been on the run from Mubo to Komiatum. The Japanese tried to press on with a counter attack aimed at Winterflood’s B platoon. The Japanese tossed mortar and machine gun fire, but received terrible losses to the commandos, forced to pull back up Walpole track. The next day Warfe ordered Winterflood’s platoon to make a frontal assault, but quickly found themselves pinned down by machine gun fire and during the night received a heavy counter attack that forced them to dig in. The Japanese continued to block the way, covering their withdrawal further east, but all the mayhem prompted General Savige to relieve the commandos by tossing up companies C and B of the 2/5th who adopted the name Bennett force as they were led by Captain Cam Bennett. The rest of the 2/5th marched up the Buigap.

Meanwhile General Herring was dealing with a supply issue for the 3rd Australian division. The 3rd division was too far from the coast and thus had been relying on supply via airdrops, which we have seen during this series to not be particularly accurate and quite inadequate. The supply problems mounted more when the decision was made to target Lae as such a campaign required building up reserve dumps. Warfe’s men were critically low on supplies; the 58/59th had nearly used up all the supplies they received, being brought up via the Missim Track and from airdrops. Getting further and further away from the source of supplies and with declining carrier capacity, Warfe’s men were reaching starvation point. Further back, Companies A and C of the 2/6th battalion got drafted the job of moving the supplies from Mubo to Buigap creek. General Herring considered it extremely difficult, but not impossible to maintain further units in the Salamaua area, if they were closer to the coasts. To solve the problem General Herring designated Tambu Bay as a new coastal base for supplies and it would also help as an artillery position.

And thus, the 3rd battalion, 162nd regiment of Major Archibald Roosevelt landed at Nassau Bay back on July 12th commencing with their coastal advance. They were accompanied by Brigadier General Ralph Coane’s artillery that had landed prior to them. Yet their advance would begin in an extremely confused and chaotic manner. The question of command was at the core of the issue, General Fuller had decided to separate units such as Archibald Roosevelts from the MacKechnie Force, and thus they were now placed under the command of the Coane Force. General Herring was forced to intervene, placing the Coane Force under General Savige. At the same time, Colonel MacKechnie was relieved of his command because Fuller felt that he had favored the Australians over the Americans. To dig depper into this mess, what occurred was General Savige and Colonel MacKechnie were both unaware that two-thirds of the 162nd regiment had been allocated to the Coane Force when General Herring sent the a confusing message to try and clarify things “all units MACK force are under operational control of 3 Aust Div”. Troubles began at Moten ordered Major Roosevelt to advance north, but Roosevelt had also been told by General Fuller that he was not under Australian command. Thus Roosevelt bluntly replied to Moten “For your information I obey no orders except those from my immediate superior”. Then MacKechnie tried to smooth things over with Moten when he was informed of Fuller’s position. He apologized for Roosevelt’s message, and tried to speak about how great all the Australian/American cooperation was going. Fuller and Herring then tried to clarify the situation by placing the Coane Force under General Savige, but Fuller also decided to dismiss MacKechnie, mostly because he had relinquished command of his men to the Australians and thus had failed to protect American interests. As I say on my personnel channel, often when talking about China’s Warlords in the 1920’s, this is some kindergarten bullshit.

Back to the action at hand, the Coane Force was being aided by a Papuan company who were scouting ahead of the Americans. They managed to confirm that Tambu Bay and the Dot Inlet were occupied and fortified by the Japanese. A platoon of the 5th Sasebo SNLF and the 3rd battalion, 66th regiment were holding a position on Tambu Bay while the remnants of the 3rd battalion, 102nd regiment were on a ridge overlooking the bay, which would later be named Roosevelt Ridge. On July 18th, Roosevelt led the troops with Companies L and I taking the lead, guided by two Papuan platoons. L Company with a Papuan company advanced along an inland track while K Company likewise did so along the coast. K Companies’s Papuan guides hit a Japanese outpost south of Boisi on July 18th. On the morning of the 20th, the Papuan platoon managed to kill four Japanese before K Company helped destroy the outpost. By the 20th they seized Boisi and Roosevelt with the others approached the Tambu bay. Roosevelt had Coane’s artillery support, they brought up four 25 pounders of the 2/6th Australian field regiment originally placed at Nassau Bay along with 2 batteries of the 218th American field artillery battalion, 8 75mm guns from north Salus, a battery of the 205th American field artillery battalion and 4 105mm guns. Under the cover the artillery they attacked the enemy, but they were met with heavy mortar fire coming from Roosevelt Ridge. Roosevelt Ridge extended westwards from the sea for nearly 2000 yards, forming kind of bulwark that shielded the northern end of Tambu Bay. Thus Tambu Bay could not be secured unless the ridge was taken first. The Australian broadcasting commission correspondent, Peter Hemery described the ridge like this “a piece of old style razer blade jutting into the sea”. According to some Japanese sources they had this to say of it “The area around Boisi had a lay of land most suitable to the arrest of the enemy advancing northward along the coast”

General Nakano had also decided to reinforce the ridge with 250 men of the 1st battalion, 115th regiment, but of course this came at the coast of Salamaua’s defense. By this point the bulk of the 102nd regiment was at the Malolo-buang coastal area and the bulk of the 115th regiment, the 2nd Maizuru SNLF, two companies of the 5th Sasebo SNLF and the 14th field artillery regiment were at Salamaua, around 150 men in total. On the other side, after the fall of Mubo Brigadier Moten had the men advance north. The Bennet Force took over Goodview Junction; Companies A and D of the 2/5th advanced to Mount Tambu. Mount Tambu was the highest feature along the route between Mubo and Salamaua. It consisted of a series of razorback ridges covered in dense jungle, ideal for camouflage pillboxes. Its area was defended by roughly 700 Japanese from the 2nd and 3rd battalions of the 66th regiment led by Lt Colonel Fukuzo Kimura and Major Sakai Sugiyama. On July 16th, Captain Mick Walter led 60 men of Company A up the steep track leading to the south crest of Mount Tambu. Walter led the men to storm the two forward knolls, taking the Japanese by complete surprise. The two knolls were captured, but during the night the Japanese counterattacked in force. The Japanese crawled up the knolls through some heavy undergrowth before they unleashed mortars and mountain gun fire. Walters men however had captured some Japanese pillboxes upon the two knolls and thus the turn tables. 8 counterattacks were tossed at Walters men, each repulsed with heavy losses, around 39 casualties for the Australians and 350 for the Japanese. The following day, D company came up to help the Australian defenders, bringing much needed mortars. They dug in on a knoll around 300 yards back on the track. Alongside D company also came much needed supplies and an additional platoon to reinforce his men who he deployed on his western flank. 

On July 18th, Walter ordered an advance going northwest in an attempt to secure the southern portion of Mount Tambu. The advance was spearheaded by Lance Corporal Jackson who alongside his comrades tossed grenades into a Japanese pillbox. Jackson then stormed inside killing 3 Japanese with this Tommy gun. Alongside Jackson, mortar and mountain gun fire aided Walters men to gain 80 additional yards, securing the southern portion of Mount Tambu. They could advance no further however as it became much more difficult from this position as the Japanese basically were encircling them upon razer back ridge to their north. Walter would write later on “we dug in on the new ground and shortened our perimeter to the narrowing plateau”. For this action the Australians paid with 6 lives, 13 wounded while the Japanese lost 82. At this point Walter had D company with one of his platoon holding the western flank; A company held the northern knoll and two platoons from D company held the eastern knolls.

The Japanese had been devastated, losing hundreds of men and allied artillery was becoming a nightmare. Captain Newman’s C Company of the 162nd battalion had come to a junction of the Buigap and Bui Eo. From there a reconnaissance patrol found suitable artillery positions northwest of the junction. With the help of native carriers and 80 men of the 2/6th battalion, two guns were hauled over the Buigap track and by July 17th another 4 guns of the American 218th battalion were hauled up from the southern arm of the Bitoi river to Green Hill. From these positions the allies could smash multiple Japanese defensive positions. General Nakano realized Mount Tambu was an essential component of General Muroya’s defensive line so he sent the remainder of the 3rd battalion, 66th regiment to reinforce Colonel Araki’s men.

Then during the early hours of July 19th a large earth tremor startled the Australian defenders. It was the prelude to an assault led by Captain Kunizo Hatsugai’s 9th company of the 66th regiment. They had crept up silently managing to get behind the southern knolls then suddenly charged up under the cover of darkness. But the defenders had their guard up and were not taken by surprise. A Bren gunner managed to knock out one of the Japanese raiders machine guns with a lucky hit in the dark. As the Japanese scrambled to try and recover it they were met with fire causing severe casualties. The Japanese surprise attack was a failure, forcing them to withdraw by first light, leaving 21 dead across the knoll. While this raid was occuring, Walters men were also repelling a series of attacks against the Northern Knoll. During these attacks, Walter was injured. Luckily for Walter and his company, they were relieved on the 19th by D Company. Another American unit, C Company of the 1st battalion, 162nd regiment led by Captain Delmar Newman also arrived to take up a position on the southern knolls. Until july 23rd, the Australians limited their actions to patrols. On the 20th, Bennet led a patrol making contact with a strong Japanese position on the Walpole track; Another company led by Morse found a Japanese position in the Goodview area dug within 100 yards of their own. Meanwhile the Japanese also limited their actions to a few patrols proding Mount Tambu for weaknesses.

 

On July 23rd Moten ordered the 2/5th battalion to attack the remaining Japanese positions on the Tambu Knoll, but it was the most heavily fortified yet. Basically it was like a castle keep, complete with a ravine for a moat, near vertical walls and deep tunnels going through the knoll. Mount Tambu’s peak held  10 log reinforce bunkers connected by the tunnels which could shelter half a battalion or so. They also had a chain of weapon pits set up on lower ledges. Later on when investigating the entire system, the allies found weapon pits to be around 4 logs thick, interconnected by crawl trenches. Many of these weapon puts had been carefully sited within the roots of large trees, making them impervious to allied artillery fire. The tunnel entrances were dug into the side of the peak directly behind the defensive positions, allowing the defenders to storm out from their shelters underground within seconds. It was these kind of ingenious defensive works that would be built upon later on in the war to create absolute nightmares for the allies.

 

Moten had not carried out a thorough reconnaissance of the Japanese positions prior to ordering the attack and thus many of his subordinates elected to make a frontal assault instead of encircling them. D company took the center for the frontal attack while to the left were the 16th platoon led by Sergeant Alvin ‘Hungry’ Williams and the 18th platoon led by Lt Bernard Leonads; and A company advanced along a Caffins track heading for the western flank of Mount Tambu to try and cut off the main Japanese supply route going back to Komiatum. 15 minutes before they charged, Australian and American artillery and mortars fired upon Mount Tambu. Two Australian mountain guns fired 90 rounds while the 4 75mm American guns fired 60 per gun from Green hill. D company began their attack around midday, trying to drive a wedge between two lines of pillboxes. Corporal John Smith laid cover fire as Captain Lin Cameron crept forward, getting within 15 yards of the pill boxes on the left side of the track. Cameron counted around 7 pill boxes in two lines of defense going across both sides of the track. The steep slopes on both sides gave little venues of approach, allowing around just a platoon at a time. There was also sharpened bamboo pickets on the left flank, leading Cameron to believe that an attack was expected there.

 

The Japanese knowingly let two platoons reach their line of forward pillboxes before unleashing hell upon them. The casualties were terrible. As Cameron recounted, “we were within 20 meters of the enemy bunkers before all hell let loose”. One of the men in the forward sections was killed outright, Cameron was wounded, his right elbow was shattered by a machine gun bullet. As he saw his men hesitate, he screamed out “forward! Get stuck into them!” With his right arm now useless and his eyesight dimming, Cameron handed command over to Lt Martin. Despite the horror, the Australians pressed on. Corporal Carey led his depleted platoon forward in a great dash and swept the outer ring of the Japanese pillboxes. On his left were Leonards men who stormed two pillboxes before heavy enfilade fire pinned them down. Then the 17th platoon led by Corporal John Smith charged up Mount Tambu from behind with their bayonets fixed. Smith screamed out “follow me!” as he charged. 3 other men out of the 11 managed to keep up with Smith, but soon Japanese grenades began to rain down on them. The grenades caught them just as they passed a third line of pillboxes. Smith was hit, but he kept charging and when he reached the peak of Mount Tambu with his back to the enemy he screamed “come on boys! come on boys!”. Without additional support and with no indication A company were making progress over on the left flank, the 4 men on the peak were forced to withdraw. The gallant Smith had to be dragged down and would die from severe wounds two days later. Smith was decorated for bravery in Syria in 1941, when he cleared out 3 machine gun nests at a roadblock and despite being wounded during the battle of Wau he still had gas left in the tank for some more.

 

Scouts had made their way towards the Tambu saddle track and spotted Japanese soldiers, around 125 of them a full company or so. The scouts quickly realized they were outnumbered, thus when the artillery began to open up and Walter’s company moved in for the attack across the saddle, no sooner then they started the enemy halted them in their tracks. Walter had no choice but to withdraw around 500 yards south east as the Japanese were too strong. Walter’s inability to make progress in the west ultimately ruined the entire attack. Despite the defeat, Companies A and D had done very well against such a heavily fortified position.

 

Meanwhile, Warfe and his men were marching when they discovered Ambush Knoll had come back under the hands of some Japanese from the 2nd battalion, 66th regiment. On July 15th, Warfes commandos launched an attack, with C Platoon performing a frontal assault along the narrow ridge top track. There were 16 men in the attack and they found themselves face to face with well dug in Japanese. The Japanese were behind a bamboo barricade with some pillboxes scattered about. The platoon got within 50 feet of the main barricade, but the Japanese fire was too much and casualties were mounting quickly. Meanwhile B Platoon was maneuvering around the Japanese eastern flank. At 5:30 B Platoon began attacking the eastern side of the knoll. The men got behind an enemy pillbox covering the track from Orodubi, but the Japanese quickly saw the Australians and began tossing grenades at them. Despite the resistance, B Platoon managed cut off the Japanese supply line to Ambush Knoll. With their supply lines cut the Japanese were forced to withdraw

 

With Ambush Knoll back under allied control, Brigadier Hammer ordered A company of the 58/59th battalion to depart Gwaibolom and attack Orodubi from its southern flank. Even with the help of the 58/59th company, the commando’s yet again failed to dislodge the Japanese. On the night of July 19th, fresh troops of the 1st company, 80th battalion used the light of the full moon to come up the ridge. This became a staging point for them to attack Ambush Knoll, seeing artillery fire beginning in the morning to support their attack. Warfe’s commandos were manning the trenches on Ambush Knoll, turning the tables on the Japanese and inflicting heavy casualties upon them. The Japanese were forced to retreat. The next day Warfe reinforced Ambush Knoll with two Vickers guns, which gave the Japanese a nasty surprise when they attacked again. On the 20th, the Japanese opened fire with mortars and artillery before charging the ridge. They managed to get as far as to cut the Australian lines of communication, but were ultimately repealed once again. Over 14 consecutive attacks would be made on the 20th, and even more on the 21st, but it all came to nothing, Warfe’s commandos held their ground. Facing such pressure from the Japanese, Hammer still felt the greater weight of their attention was directed at Bobdubi and not towards Tambu, believing it to all be a consequence of Moton’s lack of progress. General Savige decided to order Motens 2/6th battalion to take responsibility over Bobdubi ridge. The 2/6th then came across the Japanese rear near the slopes of Ambush Knoll and began harassing them. On the 22nd the Japanese tried yet again to attack Ambush Knoll, but were beaten back firmly, forcing them to finally withdraw to Sugarcane Ridge. By July 23rd, Warfes’ exhausted commandos earned a relief by the 2/6th and were sent to relieve A company at Gwaibolom, while A company advanced north. The 2/6th likewise would advance north. But now we are moving away from the troubles of New Guinea and heading back up north to the frigid Aleutians.

After the successful seizure of Attu, now Admiral Kinkaid and General Buckner needed to plan the invasion of Kiska. Kiska was the last Japanese bulwark in the Aleutians and held an incredible underground city. There were miles of tunnels, buried ammunition dumps, barracks,  3 hospitals, dental clinics, mess halls, machine shops, warehouses, photo labs, telephone rooms, all shoved and shored with wood. Ventilation pipes connected the maze of caves and tunnels, with Japanese troops wearing great fur lined coats busy at work. The Americans had experienced hell, on Attu, over 2872 Japanese had been killed or committed suicide, just 28 men were captured and it cost 549 american lives, 1148 wounded and nearly another 2000 ill or battered by harsh climate. The American leadership expected Kiska to be another hellscape and did not want to come at it lightly. The 7th division led by Brigadier General Archibald Arnolrd, Buckner’s 4th regiment, the 87th Mountain infantry regiment, the 13th Canadian Brigade, consisting of the 6th Canadian division led by Major General George Pearkes, the Canadian Fusiliers regiment, the 1st battalion of Winnipeg grenadiers, the Rocky Mountain rangers regiment and e Regiment de Hull along with the 1st Special Service Force led by Colonel Robert Frederick were to be part of the invasion of Kiska, codenamed Operation Cottage. Unfortunately, the actual invasion will not be happening in this episode, you will actually have to wait  weeks for that one, but I just so happened to have recently done a podcast with a Canadian Military Historian named Brad St.Croix from the Youtube channel OTD Military History, the same gentleman who I interviewed for this series about the battle of Hong Kong. The podcast we recently did was on the Canadian experience of the Pacific War and the battle of Kiska is 1/3rd of it, so if you are, impatient and want to learn some neat stuff about how Canadians had to change their entire military organization and use American equipment for the battle of Kiska, check out my Youtube channel, the Pacific War channel for the full episode. 

Now the last time we spoke about Kiska, the Japanese were forced to perform a bit of a miracle to evacuate their boys. After Attu had fallen, Rear Admiral Akiyama Monzo alongside 6000 men were ordered to evacuate Kiska. To try and do this, the Japanese began by sending 13 I-class submarines of the 1st submarine squadron of Rear Admiral Kouda Takeo. Despite these Type C submarines being enormous in size, they could only carry around 150 men per trip, thus it would have took 40 successful journey’s to evacuate the entire Kiska garrison. With the US Navy fully decked out with sonar, this was not going to be a walk in the park. The efforts had begun on May 27th and by July, the submarines had managed to get 800 men safely back to Japan, but lost 300 due to american attacks. 

Meanwhile Admiral Giffen had a considerable armada to work with consisting of a trio of older battleships; the Mississippi, Idaho and New Mexico, a quintet of cruisers; Louisville, Portland, San Francisco, Santa Fe and Wichita and 9 destroyers. He was ordered to bombard Kiska who already had been smashed with aerial attacks all throughout June and early July. On July 6th, Giffen steamed towards Kiska with 4 cruisers and 4 destroyers and bombarded the island for 22nd minutes causing a handful of casualties. It was not all that impressive, but it convinced Admiral Kawase that the Americans were about to invade Kiska at any moment.Admiral Kawase Shiro realized the futility of the submarine effort and was forced to come up with a new plan. Kawase came up with a bold plan, he was going to wait for a night when a thick fog was occurring and would take a surface fleet to sneak over into the Aleutians to assault enemy warships and evacuate all the remaining men on Kiska in a single go. To be blunt, it was a dumb idea. The American warships were equipped with radar that would pick up any surface ship with ease despite any type of fog, but what was about to occur can only be described as spectacular and bizarre. 

Rear Admiral Kimura, the victor of the battle of the bismarck sea, would lead the force and he had at his disposal Destroyer Squadron 1: consisting of Yugumo, Kazagumo, Asagumo, Akigumo, Usugumo, Hibiki (one of my favorite whiskeys), Shimakaze, Samidare, Naganami, Wakaba, Hatsushimo and light cruisers Abukuma and Kiso. In close support of these there was also a covering force consisting of heavy cruisers Nachi, Maya, light cruiser Tama and destroyers Nokaze and Namikaze. The large convoy force departed from Paramushiro on July 7th with Takeo’s 1st submarine squadron performing reconnaissance. The covering force departed Paramushiro on July 10th and by July 12th the fleet was around 500 miles south of Kiska. When they took up this assembly position, the sailors were in despair to see the fog was quite low. While it did not matter for warships with radar, Kimura knew full well what allied aircraft could do to his forces if they were not better concealed. Thus he elected to wait until the fog reappaered to cover his force. But the weather did not change, the skies remained clear forcing him to head back on July 15th. Meanwhile on Kiska, Rear Admiral Monzo was frantically ordering his troops to lay out a road from the underground base to the harbor piers to help facilitate the impending evacuation. All of the Japanese on Kiska felt an impending doom placed upon them. If the Americans landed first, it was all but over for them.

Luckily, Japanese weather stations reported a dense fog would emerge over Kiska by July 25th, and unlike here in Montreal Canada, I guess these weather reporters are accurate. Kimura once again departed Paramushiro on July 22nd, accompanied by Admiral Kawase aboard cruiser Tama. Yet a few days prior, on July 19th, Admiral Kinkaid had ordered Admiral Giffen to bombard Kiska again. This time Giffen took a two pronged naval attack force consisting of battleships Mississippi and Idaho, cruisers Portland, Wichita, San Francisco, Louisville, Santa Fe and destroyers Abner Read, Farragut, Monaghan, Perry, Aylwin, Bache, Hughes, Morris and Mustin. Giffen’s force reached Kiska on July 22nd and his ships smashed the island with 424000 lbs of high explosive shells. Just an hour later, a PBY suddenly detached with her radar 7 radar pips southwest of Attu. The PBY maintained contact for around 6 hours before low fuel forced her to return to base. These radar pips alarmed Admiral Kinkaid which was being reported in conjunction with a massive increase in Japanese radio activity on Kiska. Kinkaid believed a major Japanese fleet had just entered Aleutian waters, most likely a reinforcement convoy. Kinkaid immediately ordered Rear Admirals Giffen and Griffin to intercept the suspected enemy. However, by doing this he had also done something extremely favorable for the Japanese, he had left Kiska Harbor open and unguarded. Kinkaid dispatched a quartet of PT boats to try and provide a makeshift blockade, but the terrible weather forced the smaller vessels to return to port as trying to dash over to Kiska would probably see them all sunk.

While this was occurring, Kimura’s ships were traveling through the dense fog separately. The fog prevented the Americans from intercepting them initially, and having failed to make contact with the enemy, Kinkaid became nervous the Japanese might escape the blockade and ordered the force to return to Kiska at maximum speed on July 25th. The American ships dutifully turned back while Kinkaid sent the Oiler Pecos out to meet them for refueling. By dusk of the 25th, the American ships were around 90 miles from Kiska, when the fog had all but disappeared showing a cloudless sky. Kimura’s vessels seeing their fog betray them, all reunited as a single force, now bearing 400 miles south of the American warships. At precisely 12:43am on July 26th the American warships picked up 7 strong radar pips around 15 miles northeast. It was Mississippi’s SG radar that first picked them up, the American destroyers were actually unable to detect any pips on their radar due to the curvature of the ocean's surface at such a distance. The New Mexico, Portland, San Francisco and Wichita began picking up the same radar pips. The radar pips zigzagged across the sea surface, changing direction in much the same way ships attempting to evade detection might. The ships were being detected all at different angles, verifying to the Americans there were physical presences of some kind occupying definite points in space. On top of this, the immobile radar signature of Kiska’s volcano at a range of 78 miles appeared clearly the entire time, verifying the validity of the pips moving with a fixed landmark. The radar pips converged 22,000 yards ahead of the Americans forcing them to spring into action.

Admiral Giffen called for the entire fleet to turn left to intercept the pips on their southerly heading and in the hopes of foiling a possible torpedo attack. All of the American ships turned their guns to fire salvo’s into the night. Great flame lances stabbed into the darkness as destroyers launched volleys of torpedoes and radar plotters frantically calculated salvo corrections. For 67 minutes the Americans tracked the 7 radar pips firing wildly at them. At 1:30am the Mississippi’s log recorded zig-zags and a 20 degree course change, but not a single sailor saw an enemy ship. Cruisers San Francisco and Santa Fe registered shell splashes, but never an enemy target.  75 miles over on Kiska, the Japanese were watching a spectacle. From their point of view it was like a night-time light show over the horizon. By 2:22am the radar pips thinned, faded and vanished completely. During the morning surface ships and aircraft fanned out looking for wreckage, ships, floating papers, oil slick, anything to indicate something was even out there! The American warships reported no return fire, it was as if they faced ghosts. With a lack of fuel and ammunition, the US ships began refueling on the 28th and resumed their blockade of Kiska.

What famously has become known as the battle of the Pips left the US Navy with a mystery that remains unsolved to this very day. The radar equipment was operating at times where there was a cloudless night with no fog, zero reasons for false radar echoes. An Aleutian crab fishing captain named Captain George Fulton may have solved the mystery in 1991 when he managed to duplicate the radar signatures observed during the battle by using his radar on a natural phenomenon common to the area. He presented his findings to the Alaska War Symposium in 1993 in a letter “I […] duplicated the Battle of the Pips using color radar. Sure enough there were blips on the tube and their density changed from red to orange to yellow and finally to black, providing an exact replication of the Battle of the Pips. What you described fits exactly the […] pattern of dense flocks of mutton birds or dusky shearwaters […] As mutton birds fly they veer left and right. This accounts for the zigzagging that was reported on the radar logs” Captain Fulton further went on to say how these huge flocks continue until they see large schools of fish, such as pollack. When the birds see them they begin landing on the sea surface then dive for their prey. This maneuver causes them to vanish from radar screens entirely. In the 1990s Aleutian fishing crews use this trait to locate large concentration of pollack, identifying the blips by their zigzagging motion and cast their nets accordingly. Were the Japanese saved by shearwater birds?

Another answer came from the US Navy who officially stated that atmospheric echoes, a sort of phenomena caused the radar pips, that explanation has been highly contested. Its also been speculated that the American radar pips were 7 IJN submarines running reconnaissance. What we do know is Kimura made it to Kiska on the 28th undetected and unharmed while the US warships were enroute miles back. No American ships were anywhere near Kiska on the 28th. Admiral Kimura pulled the ships into Kiska anchorage and evacuated the entire remaining forces on the island, all 5183 men onto 8 vessels all within 55 minutes. The Japanese soldiers made sure to spend their last moments on the island setting up a plethora of booby traps. Four days later Kimura and Kawase were back in Paramushiro, successfully evacuating Kiska without firing a single shot. The Americans had no idea the evacuation occurred. In the words of one disgruntled American Colonel after the Kiska ordeal ““How I hate those bastards but I've got to give them credit for the most masterly evacuation by any army at any time and I'm not forgetting Dunkirk”

The drive to Lae and Salamaua rages on New Guinea as the American Navy in the frigid northern seas fought perhaps a ghost ship army. Or perhaps some pesky birds looking for tasty pollock saved the entire Japanese garrison on the island of Kiska. 

- 87 - Pacific War - Drive on Munda point, July 18-25, 1943

Last time we spoke about the allied offensive against Mubo and the naval battle of Kolombangara. The Australians and Americans were continuing the drive towards Salamaua and Lae, but in their way was the once heavily fortified area of Mubo. Because of intricate diversionary attacks in multiple places, the Japanese gradually lifting their defensive positions in Mubo, until the time was ripe for the allies to seize it. The Pimple, Green Hill and Observation hill, places that caused suffering and hardship were finally seized, Mubo was secured. Over in the Solomons, the New Georgia campaign was continuing, forcing the Japanese to make another daring Tokyo Express run like they did at the battle of Kula Gulf. Yet again Admiral Ainsworth went out to face the enemy, completely ignorant of their torpedo capabilities and he paid for it dearly. Today we are going to continue these stories.

This episode is the Drive on Munda Point

Today we are starting with the main drive towards Munda. We are picking up from last time where General Wing had finally begun his main advance on Munda on July 9th. Now the landings had occurred on July 2nd, from then on the Americans were busy making another landings such as at Rice Anchorage, getting forces to assembly points and trying to hinder any efforts by the Japanese to reinforce Munda. If you were looking down upon a map it would basically look like multiple forces taking up positions that cut off trails and ports that extend towards Munda. Everyone had a unique task and a time table, but as we all know not everything goes according to plan. When General Wing ordered the main advance, two infantry regiments were greatly delayed, those being the 172nd who moved a grand total of 1100 yards and the 169th who made zero ground at all. The war planners had not considered how difficult it would be for ground forces to travel the single narrow tracks, dense jungles, mangroves, creeks, ridges and ravines. The men found navigation difficult and whenever the terrain seemed to narrow they found Japanese defenses. The 172nd were ordered by Major Genera Hester to carry out flanking maneuvers against a roadblock set up by the 9th company, 3rd battalion, 229th regiment while the 169th attacked them frontally. They were supported by heavy artillery, naval bombardment and aerial bombing. But General Sasaki correctly predicted the American commanders intentions and responded to them rather quickly with his own counter flanking maneuvers. His forward area was held by Japanese snipers, well concealed in baskets in trees whom employed rifles that gave little to no muzzle flashes, something that was turning into a real trait of the Japanese. 

The 172nd progressed a few hundreds yards with its 1st battalion leading the way, the 2nd behind them and the 3rd following from a distance. They were assaulting a point where the Munda trail intersected another trail running southwest to a beach and southwest of this were the native villages of Ilangana and Laiana. The Japanese managed to keep them 1500 yards away with this defenses. The Artillery was not working to dislodge the Japanese from their roadblock and during the night the Japanese were reinforced with some units of the 11th company who took up some high ground later called Reincke Ridge. This made things ever worse for the inexperienced and pretty brutally shaken 169th who had the unfortunate job of meeting them in a front assault.

Things were becoming even worse for General Wing. Despite the slow progress, the American forces had actually overstretched their logistics by July 10th. The 118th engineer battalion had been making some good progress building a jeep trail going from Zanana to the Barike River. They relied on information provided by native scouts, and the engineers built the trail over high dry ground, averaging around half a mile or so per day. But the 5 foot deep fast running stream east of the Barike caused a ton of soft mud, not  very engineer friendly. To get the ground firm enough for footbridges and such they were forces to swing the road northward parallel to the river for over 2 miles. This gap between the end and front of the road meant near half of the combat troops were forced to carry forward ammunition, food, water and other supplies and let us not forget everyone who gets sick or wounded needed to be carried back on the same roadways. Again, logistics are not as sexy as the combat and don’t usually get much time of day, but its important for any war effort, hell look at Russia today.

To solve his logistical headache, General Hester decided to divert the 172nd infantry regiment south towards Laiana, while the 169th would continue their miserable advance up the Munda trail. Now Laiana was just 500 yards east of the main Japanese defensive line at Ilangana, currently held by the 2nd and 3rd battalion of the 229th regiment and 2nd independent Quick-fire battalion all under the command of Colonel Hirata Genjiro. The 172nd would have the support of the 3rd battalion, 103rd regiment and 8 M3 Stuart tanks of the 9th defense battalion who were expected to land at Laiana by July 13th.

On the morning of the 11th, the 172nd began turning south wading through knee deep mud and having the Japanese fire mortars upon them. By midway they had advanced 450 yards when they came across some Japanese bill boxes. While this was going on the 169th were pushing against the Japanese upon the high ground leading to a stalemate. Because of this Colonel Temple Holland replaced Colonel Eason as commander of the 169th and Colonel Frederick Reincke took command of its 3rd battalion which was being led by Major William Stebbins. On July 12th the Colonel Holland began a plan calling for the 1st battalion to attack frontally while the 2nd battalion enveloped the Japanese left flank. The 3rd battalion who were in reserve were released to engage the enemy, but the entire thing bogged down immediately as units became intermingled with the 172nd who were on their way to Laiana.

Meanwhile Rear Admiral Aaron Merrill with task force 36 was ordered to depart Ironbottom Sounds and provide naval bombardment from the Blanche Channel in coordination with heavy artillery in Rendova and aerial bombing from AirSols. Merrill took 4 light cruisers Columbia, Cleveland, Denver and Montpelier into the narrow channel while his two destroyers Farenholt and Buchanen took up a position near the Munda Bar to shell the Kokenggolo Hill Area. Merrills force fired 8600 shells for 40 minutes, which did clear the jungle in front of the advancing troops, but ultimately did little else as they were forced to fire a mile in front of the American positions, but within that mile were the said Japanese defenses. As you can imagine, the boys on the ground were all too excited to now advance, only to find the same unhampered enemy facing them. The 1st battalion, 169th regiment managed to gain about 300 yards; the 2nd battalion received enfilading fire from a ridge to the north, unable to progress and the 3rd battalion assaulted the southern ridge for several hours enjoying some artillery and aerial support. To the south the 172nd were stuck in front of the pill boxes. These pill boxes were not made out of concrete, but instead coconut logs and coral, pretty ingenious stuff. They ranged from 10-12 feet square, with 3-4 layers of logs banked with 6-8 feet of weathered coral. Their ceilings were usually around 10 feet from the floor, dug into the earth so that 2-4 feet of the pill box projected above the ground. Each had several firing slits for riflemen or machine guns. Outside the pill boxes were foxholes, and trenches connected all positions. All of this was well camouflage using earth, grass, vines, palm fronds and such, leading Americans to stumble onto a pill box without even noticing it. One remark made by the 43rd division after coming across them was that they had an easier time smelling them than seeing them. So if you ever watched classic Pacific War films or the Pacific Series and wondered how some of these pill boxes were made, there you go. 

On the morning of the 13th Colonel Holland requested some aerial support and he got some at 10am. 12 Dauntless dropped 1000 pound daisy cutters upon some smoke markers laid out by the 169th. The dive bombers manage to hit the target perfectly before Holland ordered the men to charge. The 2nd battalion went through the center, while the 1st battalion took the right and the 3rd battalion took the left. They hit the north and south ridges trying to envelop the Japanese. E and F companies of the 2nd battalion ran into heavy machine gun fire, causing a halt. The 1st battalion tried to climb the north ridge but were obstructed by a ton of felled trees and craters due to the bombing. The Japanese who survived the bombardments opened fire from their pillboxes keeping the Americans in check. The charging Americans now without artillery or mortar support tried to push forward with rifle and bayonet, seeing many killed upon the crest or wounded. Company B would lose 3 of its 4 officers alone. The 3rd battalion now led by Colonel Reincke fought for some hours managing to progress 500 yards into the Japanese lines securing the south ridge. They fought pillbox through pillbox, it was a terribly bloody affair, resulting in 100 casualties. When they took the ridge they held the position, beating back several counterattacks during the night, to which the men named the ridge Reincke. Soon the 1st and 2nd battalions took up positions on the 3rds flanks securing Reincke ridge, while the Japanese concentrated on the northern ridge and to the west they held a higher ground called Horseshoe hill.

Meanwhile the 172nd had their lines of communication cut off in their rear by the Japanese forcing them to quicken up the pace as they were running low on food. They made it to Laiana beach in the late afternoon successfully securing the beach and organizing defensive positions. The following morning General Hester landed the 3rd battalion, 103rd regiment and the tanks to back them up at Laiana. This came also with some much needed supplies for the worn out men. Having supplied the men to the southern beach, now the men in the northern front required resupply. Reinckes men were tossing back more counterattacks. One morning Japanese artillery fired upon the ridge bursting a tree that killed 4 men and wounded 23. Alongside this 5 men were reported to have a case of shell shock, 7 others war neurosis. Machine gun fire claimed 2 men, wounded another 5. At 8pm artillery began again killing another 8 men and wounding 26. There were no medical officers with the battalion, leaving medics to do what they could. Despite the hardship the 3rd battalion held their ground, and gradually the Japanese evacuated the northern ridge which the 2nd battalion quickly seized.

By July 15th, the 4rd divisions engineers had managed to complete the jeep trail from Laiana to the 169th area. Telephone lines crews began to lay underwater cables between Zanana, Laiana and General Barkers artillery teams. Engineers also finished a bridge over the Barike on the 12th and on the 14th had extended the trail within 500 yards of the 169th front lines. Supply lines were finally being secured, and more importantly the wounded would be able to be safely transported. By July 17th, the 43rd division had 90 deaths, 636 wounded in actions and over 1000 cases of sickness ranging from the ever present friend malaria, but also diarrhea, dysentery and such. As mentioned, cases of psychological problems were also very apparent. Half of the 43rd division were suffering war neurosis, which we call today Combat Stress Reaction “CSR”. This is an acute reaction from the stress of war that causes the combatant to feel fatigued, have slower reactions, be indecisive, and can become disconnected from one's surroundings. It’s classic psychological trauma, kind of similar to what I assume many of you listeners would think of as PTSD, but it is not the same thing, PTSD can see durations lasting months if not even years, while CSR has a short duration. Small tidbit of info since my first degree is in neuroscience, a fairly recent study in the later 2000’s was done to look at the issue of CSR, shellshock and such from a neurological point of view. The idea was to figure out if specific physical damage was being done to parts of the brain during blast trauma that caused combat stress reactions. The reason the study was done was because the symptoms from such maladies often overlap with things you see in traumatic brain injuries, anyways was interesting reading back in my uni days.

As pointed out by historian Samuel Eliot Morison, it seemed General Hester’s choice of sending the 172nd infantry regiment south, had greatly exposed the inexperienced 169th. In his words “This was perhaps the worst blunder in the most unintelligently waged land campaign of the Pacific war (with the possible exception of Okinawa). Laiana should have been chosen as the initial beachhead; if it was now required, the 172nd should have been withdrawn from Zanana and landed at Laiana under naval gunfire and air support. Or Hester might have made the landing with his reserves then waiting at Rendova. As it was, General Sasaki interpreted the move correctly and by nightfall had brought both advances to a standstill.” In order to break the deadlock that was occurring, some of the command structure would be reorganized. This coincided with half of the 4rd division being knocked out of commission, prompting General Hester to request reinforcements for the drive against Munda.

General Harmon performed a inspection of the situation and reported back to Admiral Halsey on Guadalcanal. He advised sending forward General Oscar Griswold of the 14th corps with a forward echelon of staff so he could begin building up the administrative, supply and planning for the future New Georgia occupation force. Once Munda had fallen, this would allow General Hester to carry on against Vila. Harmon justified this by stating Hesters force was too small to do it, but there was another rationale. By doing this it would relegate Admiral Turner to a supporting role, whom the army and marines were resenting because of what they deemed to be his meddling of ground operations. Admiral Turner opposed the idea, and Halsey replied to Harmon he could simply increase Hester’s staff. This prompted Harmon to fly back to COMSOPAC HQ on Noumea to personally talk to Halsey and force the issue.

Griswold showed up at midnight on the 15th assuming command of the occupational force, leaving Hester to focus on the actions of his 43rd divisions offensive. Griswold began his new task by directing Major General Robert Beightler to the rest of the 37th division to New Georgia alongsideColonel Collins 161st regiment of his 25th division. Over at Zanana, the 1st battalion of the 145th regiment arrived at 5pm, which Colonel Holland tossed up to help reinforce the 169th.Now that Admiral Turner was relieved as commander of the South Pacific Amphibious force, his new orders were to take command of the central pacific offensives, replacing Admiral Wilkinson.

Now General Hester was preparing for a corps level offensive, but it would take over 10 days to build up and in the meantime the Japanese began to prepare a major counter offensive. On July 16 and 17 some small attacks were performed against the Ilangana line, supported now by the newly arrived tanks, but a lack of coordination between the 172nd regiments infantry and tanks led to only a bit of gain. Nonetheless the tanks did help against the pillboxes. The tanks took up a wedge formation and used their 37mm guns with high explosive shells to dislodge the panicking Japanese trying to fight back with their machine guns from many of the forward pillboxes. However the Japanese were only phased by the arrival of the tanks for about a day as on July 18th they started to employ anti tank strategies to great effect. The Japanese defenders began tossing a mixture of mines, molotov cocktails and flame-throwers, forcing Griswold to withdraw the remaining tanks and ordered the transportation of the 10th defense battalions tanks to reinforce them. 

Meanwhile the 169th regiment were advancing southwest towards Kelley Hill located 400 yards southwest of Reincke Ridge. They faced little opposition, but would soon see wave after wave of Japanese counterattacks to dislodge them. On the other side, the 1st and 3rd battalions of Colonel Tomonari’s 13th regiment had arrived at the scene and managed to bypass Colonel Liversedge’s roadblock. General Sasaki planned to toss Tomonari around the American’s right flank near the east bridge over the Barike river. From there they could advance upon Zanana Beach. By July 14th, the 1th regiment were marching to the upper Barike, but the men lacked maps and were hacking their own trail. Tomonari said of this  “If we had to go round and round in circles in the jungle, not having been able to find the enemy, nor having been able to help the 229th Regiment and let them die, it would really hurt the reputation the 13th Infantry Regiment had had for a long time, since the Sino- and Russo-Japan War. That was why most soldiers were feeling the pressure. Finally meeting the enemy at that point was like meeting Buddha in hell.” It would take them  days to march through the thick jungle. On the night of July 17th, Tomonari and the men found a jeep trail heading towards General Hesters HQ on Zanana Beach. He ordered his men to attack the area which at this time was being guarded by a platoon of the 4rd reconnaissance troops and 70 Fijian commandos led by Captain David Williams. General Hester was not at the HQ at this time he was at Laiana, but Generals Wing and Barker were. The Japanese launched simultaneous raids against the engineer and medical bivouacs and 43rd divisional command post. At the same time Captain Kojima of the 229th regiment launched an attack against Kelley Hill on the 18th. At 10am Japanese machine guns north of Kelley opened fire as riflement charged the its western slope. The 1st battalion fired upon the charging Japanese as the 3rd battalion fired upon the machine gunners to the north. The Japanese assault was threatening to break the line. Many of the Japanese managed to crawl within grenade tossing distance of the northern line of the 1st battalion, but mortar fire forced them back. It was an extremely bloody attack and the 1st battalion reported finding 102 dead Japanse upon the slopes at daybreak. Another predawn attack was launched by the 2nd battalion 229th infantry against the 3rd battalion, 103rd infantry but they repulsed it. The attacks were done to prevent the American troops there from helping the Zanana defenders. If all went well, Sasaki could destroy the 43rd divisions rear installations cutting off major lines of communications to the surrounding front line forces.

Tomonari’s raids however were chaotic and disorderly. Rather than a organized assault, it fell into a series of separate smaller raids allowing the few reconnaissance and Fijian commandos to fend off the invaders. The reconnaissance forces repelled the attacks upon the engineer and medical bivouacs while the Fijian commandos manned a perimeter alongside Headquarters personnel such as drivers, medical orderlies, clerks, everyone grabbed a rifle despite many not even using one since basic training. The Fijians had better eyesight at night than anyone else and showcased their abilities to the Japanese who were certainly not used to being contested in this field of expertise. Tafa a Tongan, was firing from his foxhole when a Japanese officer wielding a katana and a grenade in the other hand charged at him. Tafa used his Owen gun to mow the man down killing him. The Japanese officer was found later to be carrying documents showcasing the full strength of the Japanese force and details of their mission. The Japanese were screaming as they charged from all directions as the close quarters melee raged on. The Japanese managed to infiltrate the perimeter multiple times, destroying communications equipment, but they could not reach the most important part of the area, General Barkers artillery. Barker unleashed a tight box barrage from extremely close range to devastating effect. The Japanese had no other option than to flee up the jeep trail they came from. Tomonari had his surviving forces erect some road blocks for the next 3 days, but Sasaki’s hopes of knocking out the 43rd divisions HQ were thwarted.

Having survived the major counter offensive, the 148th regiment was quickly landed at Zanana on the 18th and were soon sent over to Reincke Ridge to relieve the poor 169th regiment. Colonel Stuart Baxter of the 148th regiment was surprised by the roadblocks as Griswold never warned him about them. His advance parties were ambushed leading to 2 deaths and some wounded. During the night the Japanese were found drunk off looted whiskey they had taken from a rations dump near the bridge on the Barike. There was a clash where a platoon from the 169th were bringing wounded men down. The drunken Japanese managed to kill many of the wounded men being carried on litters alongside 2 medics. The bridge henceforth was called “Butchers bridge”. The next morning at 8am, Baxter sent his 1st battalion and his HQ up the jeep road to fight the Japanese, but as they went up it seemed the Japanese had withdrawn. Baxters men crossed the east bridge without incident, but as they went further up the road suddenly Japanese machine guns opened up on them. A company lost over a dozen men to this ambush and soon the Japanese were attacking his flanks forcing Baxter to dig in. By July 21st the Japanese would finally depart the area allowing the 148th regiment to relieve the 169th.

As for the 169th, they were sent over to Rendova and General Beightler took command of the 37th division whom he reshuffled for an offensive. A 1300 yard line was formed north of Ilangana with Hester’s 43rd division to the south and Beightler’s 37th division to the north. By this point Hester moved his 43rd divisional command post from Zanana to Laiana where many trails were created to help with the supply lines. Griswold now planned to start an offensive on July 25th, opening up with a naval, artillery and aerial bombardment, before the infantry and tanks performed a frontal assault upon the Japanese line. The 43rd division would hit from the left to take Lambete plantation and its airfield while the 37th division would hit from the right against Bibilo Hill, thus enveloping the Japanese north of the airfield.

Meanwhile, Colonel Currin’s 4th Raiders had secured the Enogai inlet, allowing Liversedge to launch his attack against Bairoko. For the attack on Bairoko, Liversedge planned to use the 1st and 4th Raiders along the ENogai-Bairoko trail to hit the Japanese frontally, while the 3rd battalion, 148th regiment would take the Triri-Bairoko trail to hit their southern flank. Liversedge appeared to have expected aerial bombing support, but did not request or failed to request the air support in time. On the morning of the 20th, the forces began their advance. At 10:00am, Colonel Griffiths 1st Raiders ran into some Japanese outposts manned by just a handful of Japanese. They fired upon them sending them fleeing, as they continued their advance they soon came across a larger force. Eventually they were forced to a halt as they came upon the Japanese main defensive line at around Noon. Commander Okumura Saburo had created 4 successive lines of mutually supporting pillboxes on low parallel ridges running north to south. Meanwhile the 4th raiders advanced within 300 yards short of the shore of Bairoko harbor meeting the Japanese lines of defense.

At 2:30pm, Griffiths D company managed to break into the first line of defense, but an hour later, Okumura ordered heavy mortar fire from the ridges pushing the Americans back and turning the area into a killing field. The 1st raiders were unable to move forward, now resting their hopes on the 4th raiders making a breakthrough in the south. The 4th raiders ran into the Japanese main line during the midday and were not making any progress. Liversedge called the forces at the front and consequently ordered the two raider battalions to take up defensive positions further east on some high ground. The raiders had suffered 200 casualties before they retired to the south shores of Leland Lagoon. The next day, reinforcements came over from Enogai along with air support. At 9:50am 24 Dauntless, 25 Avengers and 8 B-25’s swooped in to bomb Bairoko. This was followed up at noon by 37 Avengers, 6 B-25s, then at 4pm 48 Dauntless and 25 Avengers. 130 tons of bombs his Bairoko alongside an estimated 24,000 rounds of machine gun bullets. Liversedge ordered the men to sit tight and hold their positions for now along a line stretching from Enogai, Triri and Rice Anchorage. 

Meanwhile, after the victory during the battle of Kolombangara, Admiral Samejima formed a new Night battle unit, consisting of  Heavy cruisers Kumano, Suzuya and Chokai; light cruiser Sendai; and destroyers Yugure, Kiyonami, Yukikaze and Hamakaze, led by Admiral Nishimura. Their unit was given the task of harassing American transportation efforts. Rear Admiral Ijuin Matsuji was now commanding the reinforcement unit who were going to make a run on the 17th, but this was greatly hampered by an American air strike against Buin. On the 17th, 7 B-24s, 32 P-38’s and P-40’s, 37 Dauntless, 36 Avengers and 64 Wildcats and Corsairs hit Buin. 48 Zeros began to take off from Kahili, but they could not scramble fast enough as the Americans bombed the shipping, setting a cargo ship on fire, before the Hatsuyuki took a direct hit to her forward magazine sinking her and 3 other destroyers were damaged. 13 Zeros were shot down while the Americans lost 6 aircraft. Many of Ijuins transports received some minor damage delaying his departure. On July 19th, Nishimura attempted a reinforcement run to New Georgia, but his force was intercepted northwest of Kolombangara by a pack of Avengers. Nishimura’s ships scattered at high speed upon seeing the enemy aircraft, but Yugure was successfully torpedoed and sank as a result. The Kiyonami stuck behind to grab survivors. Meanwhile cruisers Chokai and Kumano were also heavily damaged. The Kiyonami was later attacked by 8 B-25’s who bombed her at masthead level, leaving her dead in the water. The B-25’s also attacked the transports doing some minor damage to the Matsuzuki and Minazuki. 582 men, 102 tons of supplies and 60 drums of fuel were successfully delivered, but the terrible losses led to the newly formed Night Battle unit to be canned.

On the 22nd another reinforcement convoy consisting of Seaplane tender Nishin and destroyers Arashi, Isokaze and Hagikaze made a run to Bougainville led by Rear Admiral Osugi Morkazu. They were carrying 630 men of the South Seas 4th guard unit, 22 tanks and 8 artillery pieces. They were intercepted by a huge force consisting of 12 B-24’s, 16 Dauntless, 18 Avengers, escorted by 134 fighters flown by US army, Marine and New Zealanders. The Nisshin was devastated by bombs, torpedoes and strafing attacks leading her to sink within 14 minutes from the start of the interception. Of her 633 crewmen and 630 troops onboard, only 178 would be rescued later on by destroyers who faced considerable attacks from aircraft doing so. Despite the rather insane levels of allied aircraft attacks, General Imamura continued to commit more forces to the defense of the Central Solomons now assigning the elite 2nd battalion, 230th regiment “Yano Battalion” led by Lt COlonel Yano Keiji to reinforce Vila. They were sent aboard the destroyers Yukikaze, Mikazuki and Hamakaze on the night of the 23rd. Instead of sailing through the slot, they used the Wilson straight which was very fortunate as Admiral Merrill was coming up the slot with a large task force to supply Liversedge at Enogai. At Least the poor Japanese transports dodge one bullet.

The American drive upon Munda was seeing significant delays as the Japanese proved themselves very capable at defense, especially in pillboxes. However the battles to reinforce New Georgia were costing the Japanese defeats or pyrrhic victories. 

- 86 - Pacific War - Fall of Mubo & battle of Kolombangara, July 11-18, 1943

Last time we spoke about the amphibious assaults in New Georgia, New Guinea and the naval battle of Kula Gulf. The boys on New Guinea were edging ever closer to their objective of Lae while drawing the Japanese attention elsewhere. In the Solomons, Admiral Kusaka tossed as many aircraft as he could to thwart the multiple allied landings, but it was to no avail. Having depleted his airpower, now he turned to the navy to see if they could reinforce New Georgia before another Guadalcanal situation occurred. Rear Admiral Teruo Akiyama was given the task of launching a Tokyo Express to New Georgia while also trying to give some fight to the enemy. Aboard his flagship the Niizuka, Akiyama did indeed give a fight to the Americans, showcasing a brand new type of radar and the ever trusty type 93 long lance torpedoes. The Japanese landed a few of their boys and now the real fight for New Georgia would begin. 

This episode is the Fall of Mubo & battle of Kolombangara

So the past few weeks we have been chaotically juggling multiple events across the Solomons and New Guinea and this week it shall be no different. So let's first jump into New Guinea. General MacArthur’s forces managed to pull off the Nassau Bay landing, getting General Savige some much needed reinforcements on his eastern flank and a new supply route. Now the landing at Nassau Bay was part of an ongoing operation codenamed Doublet, aimed at dislodging the Japanese from Bobdubi and Mubo. Taking these were necessary for the future push against Lae and Salamaua. Mubo held an airfield and its capture would greatly facilitate troop movements towards Salamaua. The movement in the interior towards Mubo was complicated by rough terrain. There were a series of ridges that could be defended sternly by the Japanese. As we have seen for weeks, Roosevelt ridge, the pimple, Green Hill, Observation hill, Lababia ridge and Bitoi ridge proved to be very heavily defended. For the Japanese headquarters, all of the allied offensives were confusing as to where exactly the main target was to be. General Nakano remained confident, Salamaua was the main target and he acted accordingly by beefing up the defense there. He ordered Major General Chuichi Muroya, the commander of the 51st infantry division to fortify and defend Salamaua. As part of this, he also ordered Muroya to dispatch around 1000 men to halt American forces trying to move up the coast towards Lake Salus.

Now by July 2nd Brigadier Moten’s plan was for the 2/6th and 2/5th battalions to take Mubo and Observation hill. While the new Taylor Force would capture Bitoi ridge and then the ridge between Bui Alang and Bui Kumbul Creeks. After this the forces would link up and the Japanese lines of communications along the Buigap Creek would be severed. While this was going on the 15th brigade who was working in conjunction with the newly landed troops, were performing an offensive directed at reducing the Japanese presence around Lae and Salamaua. Part of this offensive involved the inexperienced 58th/59th battalion who had a hell of a time facing the Japanese at Bobdubi ridge. The 58th/59th battalion were two previous militia battalions from Victoria. Initially they were a defensive force in Australia, not meant to go to places like New Guinea, but as they say times were tough. They got a taste of hand to hand combat in late june and while they did not make much progress, they still impacted the campaign, forcing General Muroya to request reinforcements so he could maintain a firm defense for the approaches to Salamaua. Nakano made it clear Bobdubi was of grave importance stating “this location is the last key point in the defense of Salamaua”. Muroya received Major Otoichi Jinno’s 1st and 3rd companies of the 80th battalion. They marched through the Coconuts area to Bobdubi bringing with them 2 mountain guns of the 26th field artillery regiment. Meanwhile Colonel Araki his 1st battalion over to the Old Vickers position. By early July Muroya now held 5 infantry companies, around 500 men strong in all. But with all the activity hitting the north, Araki became worried and ultimately decided to move his regimental HQ and 1st battalion to Komiatum, leaving only his 2nd battalion to hold Mubo. 

On July 4th, Brigadier Heathcote Hammer took command of the 15th brigade. He was a veteran of the second battle of El Alamein, one of the most iconic battles of WW2, yours truly actually wrote quite a large episode for Kings and Generals on that one, and I think by the time this podcast comes out it should as well. Anyways Hammer had taken a German bullet right through both of his cheeks, but he did not lose a single tooth in the process, I guess lucky on that count. He earned a distinguished service order for his time in the middle east and in june of 1943 was promoted to Brigadier and given command of the 15th brigade. He was considered one of the most original and magnetic leaders of the Australian Infantry. “Hard as Nails” was said to be his motto, and “as you train, so you fight” his creed. When the 58/59th battalion stalled, he was tossed into the thick of it. Now do remember he was coming directly off the victory at Alamein, so he was I guess you can call it “desert minded” when he was tossed into the unforgivable jungles of New Guinea. He would have to deal with completely different terrain, different types of troops and a different enemy than the Italians and Germans.

Another result of the delays at Bobdubi saw General Saviege dispatched Major Warfe’s commands over to stop the Japanese from escaping Mubo. On July the 5th, General Savige ordered Hammer to send the company towards Tambu Saddle and Goodview Junction where they could cut off the Komiatum Track, thus preventing the Japanese from escaping Mubo to the north. Meanwhile B Company were on the Bench Cut Track carrying out ambush attacks. The two mountain guns brought up to the old vickers position were sporadically hitting Australian positions to their misery. C Company was performing a diversionary attack, while D Company was trying to capture the Coconuts and were successful at taking its northern region by nightfall on July 6th. The next day, the 80th regiment were pushing the 58/59th battalion back as air attacks from 6 Bostens hit the Old vickers allowing C Company to charge in with further support from D Company’s mortars. The men charged up the steep ridge into Japanese machine gun nets and pillboxes. Likewise the 1st company of the 80th regiment with support of the 1st battalion, 66th regiment were launching counterattacks out of Komiatum. The Japanese managed to ambush some Australian supply lines inflicting casualties. On July 9th, the Australians tried to charge again into the Old Vickers, through a Sugarcane Knoll, but it went the exact same as last time, the machine gun nests and pillboxes were simply too much. Bobdubi ridge proved a tough nut to crack, but all of the activity was causing more and more Japanese units to move away from Mubo. By this point Mubo was being defended by 950 men and of those 770 were front line soldiers of the 66th regiment and the 14th field artillery regiment.

And so the time was ripe to hit Mubo. Moten tossed Companies A and B from the 2/6th and C Company from the 2/5th towards Buiapal Creek; C Company of the 2/6th at Lababia ridge; D company of the 2/6th at the Saddle and the remainder of the 2/5th battalion into reserve. Warfe’s commands went to work cutting off the escape route along the Komiatum track at Goodview Junction, but his forward units were spotted by Japanese patrols. As the commandos approached the area the Japanese came down from Orodubi ambushing them at Ambush Knoll…because of course its named that, silly Aussies, and this resulted in some lost supplies. Hammer was determined not to be thwarted by any delays so he ordered Warfe to launch a counterattack immediately. The Commandos were able to push the enemy back and reclaim their lost supplies, some of which were mortars and machine guns. On the night of the 6th, Warfe was ordered to leave a force to secure Wells junction while the rest of his men would proceed to cut off the escape route.

During the morning of July 7ty, Moten’s leading companies were wading through waste deep water in the Buiapal Creek due south of Observation Hill. The allied assault against Mubo was set to begin at 9:30am on the 7th, with Mitchell bombers coming in to strafe Kitchen Creek, Woody Island and Observation Hill. After this some Botsons and liberators would likewise bomb and strafe the same targets. The view from the ground was quite the spectacle for Moten’s men. It looked like the entirety of the Mubo valley was being enveloped in thick black smoke and flames as the bombers dropped their payloads. Over 159 bombers and fighters dropped 109 tons of bombs over the Mubo area. Even if the bombs did not directly cause casualties among the Japanese in the area, it still caused chaos.

Once the air attacks dissipated, the ground forces opened up their artillery and charged. A company of the 2/5th advanced without encountered any opposition, successfully climbing the northern slopes of Observation Hill. The southern slopes proved much more difficult with the Japanese putting up a fight against B company. B Company were forced to take a defensive position in a Kunai patch southwest of the slopes of Observation Hill. During this time, the Artillery over at the beaches of Nassau Bay were being moved further inland and would arrive at Napier by July 8th. This allowed Taylor Force to have the guns necessary to launch an assault of Bitoi ridge. Taylors men managed to get to the southern slopes of the ridge by 3pm while A Company touching its forward crest. B Company likewise broke through to the north and got to a point between Kitchen and Bui Savella Creek. A Company attempted another assault against Observation Hill but was repelled again, prompting Captain Dexter’s D company to be sent to reinforce them. July 9th saw numerous patrol clashes as the Australians prodded deeper and deeper into the area. In the afternoon the Japanese sent a strong counterattack against the 2/5th companies seeing fierce fighting. As noted by Arthur Pearson of D company “In most cases we were firing blind, but sometimes we were abl to pick up the smoke from their rifles”. Pearson  at one point jumped into a weapon pit, trying to draw the Japanese fire his way. A bullet came at him, piercing the stock butt of his rifle, before slamming into one of the soldiers beside him killing the man. Pearson had no idea where the bullet had come from and frantically fired into the jungle hoping to hit the Japanese sniper. The next day saw a lot of the same, more patrol clashed. On the 10th, B Company engaged the enemy around Kitchen Creek. Meanwhile US infantry had cut the main track north of Bui Alang Creek on the 9th. The Americans began advancing down to Buigap Creek, then south to the Komiatum Track by July 10th, before hitting Buigap where they drove off a bunch of Japanese. The Americans now guessed the Japanese on Mubo were using a route north east along the Buikumbul to withdraw to Mount Tambu. With the Australian and now Americans infiltrating the sector, General Nakano ordered the Mubo garrison to pull out on the 11th, back over to Komiatum. To mask their withdrawal the Japanese planned to begin moving after sundown. By July 13th, they made their way along the Saddle to Mount Tambu, but the Americans had spotted them and gave them hell using artillery. The Japanese got out, but suffered many casualties doing so.

On July the 12th, with the Japanese leaving the area, the Australians seized the Pimple, Green Hill and Observation hill with little opposition. Thus the allies had finally driven the Japanese out of their positions near Mubo, but they had also allowed them to escape. It turned out to be quite the fiasco with General Savige and Herring both believing they controlled the US troops of the 162nd, but in truth General Fuller refused to relinquish command to either. This confusion helped the Japanese squeeze out, though they did suffer 313 deaths and 981 casualties. The Australians received around 300 casualties. Mubo had fallen, its airfield was captured, mop up operations would go on for sometime, but most of the Japanese outposts were cleared. The path to Salamaua and Lae was ever closer. But now we are heading east over to the Solomons.

General Wing’s 172nd and 169th regiments were assembling at Zanana by July 6th. Their task now was to advance along the Barike River towards Munda. Meanwhile on the northern coast of New Georgia Colonel Liversedge’s men successfully landed at Rice Anchorage by July 5th. His force was the 1st Marine Raider battalion, the 3rd battalion, 148th infantry and Companies K and L from the 145th infantry. His men began their advance south towards what is known as the Dragons peninsula. At the same time, as a result of the battle of Kula Gulf, the Japanese were able to land some men of the 13th regiment over at Vila. Defending Vila were forces led by Colonel Tomonari Satoshi. With more men on hand, General Sasaki intended to move the troops via barge through Bairoko so they could reinforce Munda. Sasaki had already brought his 3rd battalion, 229th regiment from Vila using barges. He was lucky the first time but now he felt the Americans would try to attack the airfield directly, perhaps by setting up artillery on the nearby Hopei island. Roviana island likewise could be used as a staging area for amphibious tanks to charge over. Thus Sasaki brought over some 8cm dual purpose guns and 13mm anti aircraft machine guns to try and defend the beaches. He also ordered Major Sato’s 2nd battalion of the 229th regiment to dig some anti-tank ditches along the beach with the intent to smash any enemy tanks at the waters edge. He received word of the landings made at Zanana on July 3rd, prompting him to quickly reinforce his eastern line that ran north from Ilangana point. By July 6th, he had the 3rd battalion, 229th regiment and Sato’s 2nd battalion holding positions along the the Ilangana line with a roadblock position held by a company who were using felled trees and barbed wire in front of Barike. Sasaki also had at his disposal a company of the Kure 6th SNLF led by Commander Okumura Saburo at Bairoko with a small detachment of the 2nd battalion, 13th infantry led by Major Obashi Takeo. 

Meanwhile General Wing managed to get most of his 172nd regiment to the mouth of the Barike, but the 2nd battalion of the 169th remained on Rendova and the 1st and 3rd battalions were moving inland towards the Japanese roadblock. Unfortunately for the 3rd battalion, they had not found the roadblock by the night of july 6th and dug in just a bit east of it. They did not establish a good perimeter for their fox holes, there were no trip wires or barbed wires anywhere. Thus when the darkness came, so did the Japanese from the roadblock. The Japanese performed their classic infiltration tactics. The men in the foxholes began to hear random screaming, the odd firing of rifles all around them. The Japanese began to infiltrate their perimeter with one soldier reported that Japanese troops were approaching while calling out company code names in English. It was a brutal night to be sure. The shaken men of the 3rd battalion advanced with I company leading the way. They found themselves running into Japanese machine gun positions by 10:55pm around the Munda trail. They retaliated with mortars and machine guns, but could not properly see where the enemy was. Luckily B company from the 172nd showed up attacking the roadblock from the rear. In the carnage 3 platoon leaders were wounded, K Companies commander was killed, no progress was being made. Firing lanes were drawn out, the Americans were trying to find the enemy but their muzzle blasts were tiny. Some of the Americans tossed grenades, but they could not get close enough to effectively do it. By 3:30 the 3rd battalion withdrew from what they called “blood hill” to dig in for the night, but the Japanese continued to harass them. According to the 169th infantry “it was a sleepless night spend under continued harassment from enemy patrols speaking English, making horror noises, firing weapons, throwing hand grenades, swinging machetes and jumping into foxholes with knives” 

On the 8th, the roadblock was overrun costing the 3rd battalion, 169th regiment and B company of the 172nd 6 deaths and 13 wounded. The next day the 169th finally got to their assembly point at the Barike line, while Colonel Liversedge and his men were crossing the Tamaku river. Colonel Liversedge planned to send Colonel Griffiths 1st Raiders with 2 companies of the 145th regiment to swing around the west shore of the Enogai Inlet prior to assaulting Bairoko while the 3rd battalion, 148th regiment would advance over to the Munda-Bairoko trail to cut off Munda from reinforcements. Liversedge estimated taking the Enogai Inlet and cutting off the trail would be done by July 8th, and it was critical it was done speedily as his men only had 3 days rations on hand. In the late afternoon of the 7th, the 148th managed to reach the trail and created a roadblock the following day. Griffiths team and secured the villages of Triri and Maranusa, clashing with a few Japanese patrols along the way. After capturing the villages the men came across some Japanese documents showcasing the defense plan for Enogai. On the 8th, the Raiders moved out of Triri enroute to Enogai only to run into an impassable mangrove swamp. Meanwhile Major Obashi launched a counterattack against Triri which would be eventually repelled. Griffith got the men to resume the advance using another trail west of the swamp and found themselves around Leland Lagoon where they clashed with some Japanese. 

The morning of the 9th, saw General Wings main advance began. At 5am General Barkers 3 battalions of artillery positioned on both shores of the Honiavasa passage and some 155mms on Rendova opened fire on Munda. The artillery put several thousand rounds of 105mm and 155mm high explosives upon Munda. This was followed up by a naval bombardment by the USS Farenholt, Buchanan, McCalla and Ralph Talbot who were firing from the Blanche Channel, showering Munda with over 2000 5 inch shells. Then on top of all that 107 Dauntless and Avengers dropped 79 tons of bombs over Munda, Enogai and Bairoko harbor beginning at 8:30am. The Japanese recorded that the area was lit up as if it were daytime. The 172nd regiment forded the Barike, the 169th was unable to move because of the battle against the Japanese roadblock.

On the night of July 6th, Admiral Samejima sent the rest of the troops that were supposed to be transported during the battle of Kula Gulf, the 2nd battalion of the 13th regiment, some 1200 men. They were aboard 4 destroyers, the Matsukaze, Yunagi, Mikazuki and Satsuki escorted by the cruisers Sendai and Chokai and 4 other destroyers the Yukikaze, Hamakaze, Tanikaze and Yugure. They only saw some harassment from a small strike force consisting of 5 PBY’s as they made their way to Vila and safely returned. Admiral Kusaka requested some naval reinforcements from the Combined Fleet, so Admiral Kogo send Admiral Nishimura’s Cruiser division 7, arriving on the 11th. Alongside this, Rear Admiral Izaki Shunji came over with light cruiser Jintsu and destroyer Kiyonami, taking command of the reinforcement unit.

Back on land, the Kure 6th’s batteries were firing upon Rice Anchorage prompting Griffith to begin the assault of the Enogai Inlet. Supported by mortars, B Company stormed the village of Baekineru. The Japanese began withdrawing from Enogai allowing the Americans to seize it by the 11th. This came just in time as the Raiders had run out of food and water. The raiders had paid heavily, suffering 47 deaths, 80 wounded and 4 men missing. The Kure 6th SNLF would report 81 deaths and a platoon of 50 men lost. The heavy losses forced Liversedge to request the 4th raiders be landed for the capture of Bairoko, but they would only arrive on the 18th. Meanwhile Colonel Tomonari brought forward his 1st and 3rd battalion to Bairoko to help reinforce Munda. At around 4pm, the 3rd battalion led by Colonel Takabayashi attacked the American roadblock, nearly dislodging them. By nightfall the Japanese took up a position on a ridge to the 148th’s northern flank. There was a series of counterattacks until the next day saw a bit of a stalemate, then the morning after that the Japanese backed off. The 148th regiment would hold onto the roadblock for more than a week, but would quickly run low on food. It mattered not however as the Japanese just advanced along another trail further west, prompting Liversedge to order the roadblock abandoned on July 17th.

Now Admiral Kusaka wanted to reinforce the important volcanic island of Kolombangara. Kolombangara was a perfectly round stratovolcanic cone soaring out of the sea to an altitude of 5800 feet. The Japanese had a garrison at Vila airfield on the islands southern shore. The island was often to put men and supplies upon barges that would make nighttime transits across the straits to Munda point. Kusaka sought to toss another 1200 troops, Major Yamada Tadaichi’s 2nd battalion, 45th regiment and the 8th battery, 6th field artillery. Transporting them would be Matsukaze, Yunagi, Minazuki and Satsuki coming from Buin, escorted by Admiral Izaki’s aboard the Jintsu alongside 5 destroyers Mikazuki, Yukikaze, Hamakaze, Kiyonami and Yugure coming from Rubaul. Unfortunately for the IJN, allied coastwatchers saw reported their movement and Admiral Halsey responded by ordered Admiral Ainsworth and task force 18 to intercept them. Ainsworth had light cruisers USS Honolulu, St Louis, the Royal New Zealand light cruisers HMNZS Leander; destroyers USS Nicholas, O’Bannon, Taylor, Jenkins, Radford, Ralph Talbot, Buchanan, Maury, Woodworth and Gwin. Half of Ainsworth’s forces came from Captain Ryan’s Destroyer squadron 12 who were quite inexperienced. Ainsworths set up his force making his vanguard the Nicholas followed by O’Bannon, Taylor, Jenkins and Radford. Honolulu, Leander and St Louis followed in the center. Ainsworth specifically placed Leander in the middle because she held inferior radar, he preferred St Louis to take the lead out of the Cruisers. Ryan’s destroyers would take up the rear with Ralph Talbot, followed by Buchanen, Maury, Woodworth and Gwin. By 5pm task force 18 was sailing once again for the Kula Gulf.

Task Force 18 had left Tulagi at 5pm on July 12th under clear skies and calm seas. As they passed Savo Island, Ainsworth took a course along the west coast of Santa Isabel island hoping to use it to hide his force from Japan reconnaissance aircraft. At 12:35am a PBY reported the course and composition of Izaki’s force, and Ainsworth heading in for the intercept. As the two forces were converging, Izaki dispatched his Destroyer transport through Vella Gulf to unload the troops but at 1am he was alerted of the approaching enemy. It was actually the Americans who established radar content first, but the Japanese gained visual contact by 1:08am

As the two forces converged, Izaki sent his destroyer transports through Vella Gulf; yet by 01:00, the Americans detected his force. However it was actually the Japanese who detected the Americans first for almost 2 hours or so because of the electromagnetic impulses the American radar systems emitted. The Japanese crews had managed to gain a fairly accurate picture of Ainsworths disposition. At 1:08 the Japanese made visual contact and were the first to attack, launching 29 torpedoes by 1:14am. Ainsworth’s vanguard increased speed to engage the Japanese with their torpedoes while the cruisers turned to deploy their main batters and engage to starboard. Ainsworth yet again ignorant of the type 93 long lance capabilities had no idea the fish were already in the water coming towards his force as they watched the Japanese destroyers turn away. The American destroyers tossed 19 Mark 15 torpedoes, but the Japanese were over 10,000 yards away and turning north thus completely wasted the volley. When the Japanese were 10,000 yards or so Ainsworth cruisers began opening fire, concentrating on the Jintsu.

When the Japanese column closed to 10,000 yards at 01:12, Ainsworth ordered his cruisers to open fire, concentrating on the Jintsu which was leading. Honolulu and St Louis fired an incredible amount of shells for 18 minutes at 1100 and 1360 6 inch rounds joined by 350 5in rounds. The Leander fired 160 6 inch rounds. The Jintsu was hit first to her rudder, then her bridge killing Izaki, followed by 10 or more shells to her engineering spaces. She was a doomed burning ship, that came to a dead drift quickly. The Americans then launched another volley of torpedoes, 21 in all, but they would all fail to hit a mark. By this time, the Japanese torpedoes were finally arriving. Leander was hit at 1:22 forcing Ainsworth to detach Radford and Jenkins to help her limp away. The rest of Ainsworth forces managed to avoid the torpedoes.

While this was occurring the destroyer transports had successfully unloaded the 1200 troops and were moving north to withdraw with Izaki’s other destroyers. The Japanese were not running away however, they were getting to a safe position to reload torpedoes and re-engage. After finishing off the Jintsu at 1:45, Ainsworth ordered the force to pursue the enemy going northwest. They made radar contact again at 1:56, but Ainsworth doubted the blips to be the enemy, but rather his vanguard ships. Instead of opening fire, Ainsworth attempted making contact with the vanguard force and began firing starshells, this would prove to be a fatal error. The Japanese launched another volley of 31 torpedoes. At 2:08 the first to be hit was St Louis, it opened her bow, next Gwin was hit near her No 2 engine room; Honolulu was third receiving a hit to her starboard bow at 2:11, with another hitting her stern without exploding. Honolulu’s rudder jammed and she nearly smashed into Gwin coming within 50 yards of her. That effectively ended the battle as Ainsworth ordered the task force to withdraw back to Tulagi. The Gwin had lost 61 men and was forced to be scuttled, Leander lost 28, the Jintsu 482 and another Japanese Admiral was dead. 21 survivors of the Jintsu were rescued later on by the I-180, a few others were picked up by American ships. The Japanese had won a tactical victory and demonstrated yet again their superior night fighting techniques. But it was a pyrrhic victory in many ways as well, the Americans could afford to lose ships, the Japanese could not.

 

After the defeat, Admiral Nimitz decided to change tactics and not confine anymore cruisers to the Solomons as they could not hope to chase the IJN destroyers and their troublesome torpedoes were a major threat. Nimitz wrote a letter to Halsey suggesting that a well trained squadron of 2100 ton Fletcher class destroyers would be better suited to such waters rather than cruises. Halsey argued despite the Japanese having superior torpedoes, he believed Ainsworth’s night battle plan A, that had employed SG radar with radar directed gunnery were still superior to anything the IJN had. He thought the solution “appears to be the greatest volume and weight of gunfire that can be incorporated into a highly maneuverable unit–and a unit that is certainly not appreciably weaker than the enemy unit.” Regardless Halsey went to work designating two squadrons of 2100 ton destroyers to take over New Georgia operations and would not risk anymore of his cruisers going up the Slot on any more missions.

The New Guinea and New Georgia campaigns were seeing gradual progress for the allies, but the naval battles were much less to be desired. While the Japanese were earning some victories, they were rather pyrrhic in nature as American production was winning the day.

- 85 - Pacific War - The battle of Kula Gulf, July 4-11, 1943

Last time we spoke about the amphibious assaults for Operations Chronicle and Toenails. General Douglas MacArthur finally performed his landings at Nassau Bay, Woodlark and Kiriwina islands. Woodlark and Kiriwina proved to be cake walks, while Nassau Bay proved a tougher nut to crack. Then over in the Solomons, Admiral Halsey unleashed his landings at Wickham Anchorage, Segi Point, Viru Harbor and Rendova. Now the Japanese were more alert to the invasions and offered some resistance, although ultimately Sasaki would order many forces to simply withdraw from the invaders. Admiral Kusaka tossed a ton of airpower at the incoming allies only to lose a disastrous quarter of his air fleet, forcing him to ask his Army colleague Immamura for additional support. However with all of these landings came a large amount of allied warships to bring them, and such actions could only bring about one conclusion, another naval battle for the pacific war.

This episode is the Battle of Kula Gulf

Before we jump into the naval battle of Kula Gulf a lot was occurring in New Guinea and the Solomons. Over in the Bobdubi front, the Australian 15th brigade under the temporary command of Colonel Guinn were preparing for the main offensive, hoping to trap the Japanese defending Mubo. To support the Nassau Bay landing, Colonel Guinn ordered the untested 58/59th battalion to advance upon the Japanese high ground position at the Old Vicker’s, Coconuts and Bobdubi area. They would be marching from Orodubi to the Coconuts while Major Warfe’s commandos would raid Malolo and Kela. Company A and C of the 58/59th would make the initial attack seeing A attacking Gwaibolom and C the Old Vicker’s position. Following close behind them was B company who were to advance across the ridge to gain control over the Bench Cut Track. D Company were to be held in reserve at the Kunda-vine. On June 26th, A company set off from Missim heading towards their forming up point at Namling. On the 28th, the other remaining companies made departed Meares Camp heading for the New Bobdubi kunda bridge. The next day 17 of Warfe’s commandos were ambushed by 30 Japanese. They managed to escape, but were forced to abandon a Bren gun. By the night of June 29th, the 58th/59th crossed the Francisco River and began preparations for the launch of the main attack which would occur the next morning. The next morning saw lackluster allied air strikes against Gwaibolom, Salamua, Old Vickers and the Coconut area. Companies B and C left their start up point of Uliap Creek, seeing C attack Buggert village, just a bit south of the Old Vickers position being held at this time by a company of the 115th regiment led by Lt Ogawa Takeshi. They successfully outlanked the Japanese and captured the village, suffering only 2 casualties for their efforts. From there the Australians assaulted the Old Vickers position, but the Japanese defenders repealed them right back to Buggert village. The Japanese defenders had well established positions, hiding in dugouts 40 feet down from the top. The failure to seize the Old Vickers position, prevented B Company from reaching their objective, the Bench Cut Track and now they were being met with Mortar fire as they crossed the ridge.

Meanwhile A Company began their assault on Orodubi, but anticipating booby-traps the men had left on the Bench Cut Track around 70 yards south of Orodubi, they chose to climb a 40 foot kunai slope to join the main track just 10 yards within the enemy. Around 80 men of Company 10 led by Lt Gunji Toshio saw the Australians doing this and promptly began tossing grenades at close range and fired down upon them. The Australians were forced to flee back to Namling as a result. The next day it was decided they would use a platoon to contain Orodubi while the others bypassed it to go onwards and capture Gwaibolom and Erskine Creek, which they managed to do by July 2nd. While this was occurring, B Company was trying to find another way across the ridge, but were failing to do so. So on July 2nd, they were ordered to move across the ridge via the newly established positions at Gwaibolom and Erskine Creek, and would reach the Komiatum Track / bench track junction where they would prepare an ambush by the 3rd. At around 5pm on the 3rd, B company managed to ambush a party of 20 Japanese trying to move towards Old Vickers and this quickly fell into hand to hand combat killing half the Japanese and one of their officers.

Meanwhile Colonel MacKechnie’s men were fighting to keep their beachhead alive at Nassau Bay. AA and C Companies had fought through the night against Japanese until their 300 yard perimeter was secured. At dawn on June 30th, C company began advancing south to find the Papuan infantry battalion who were around Cape Dinga. C Company made their way to a place just due west of Cape Dinga, following the Tabali River, while A Company was patrolling north and south of an arm of the Bitoi river where they ran into the 3rd battalion, 102nd regiment. A Company backed by some other units attempted to hit the Japanese western flank, but they were overwhelmed and forced to turn back. It would actually be Amphibian engineers who would save the day, who came in at the last minute to help A company out just as the Japanese tossed a banzai charge at them. Upon receiving word of the Japanese attacks, C company rushed over to join A by 3pm. Yet unbeknownst to them, the Japanese were not actually trying to break through, they were trying to withdraw by crossing the Tabali river. General Nakano had ordered them to withdraw to a new position at Lake Salus when he heard word over 1000 men had landed at Nassau Bay. Nakano also had ordered the 3rd battalion of the 66th regiment to send 150 men to march south from Salamua to help out in the Nassau Bay area. These men were tasked with carrying out only limited attacks against the allied forces around Nassau Bay, such as delaying actions to help the Nassau Bay garrison withdraw towards Lake Salus. Nakano was also coordinating with Colonel Araki who was now operating out of an HQ in Mubo, he had likewise brought forces over to Mubo from Salamua. 

As for the Papuan infantry, they were marching north and they ran into the 3rd battalion, 102nd regiment around Cape Dinga as well. They managed to attack their rear killing at least 26 Japanese who were holding out in a bunker. After this they continued their march to the Nassau Bay beachhead.

At around 4:30pm C company began sending reports that they were seeing some Japanese crossing over the Tabali River just south of their position. They were ordered to return to the beachhead perimeter to take the southern flank, but before they were able the Japanese attacked their rear taking 5 men and a platoon commander.

Around the beachhead a hastily prepared defensive line was established by an ad hoc force of Engineers, Australian infantry and Headquarters personnel. As the night fell on, C company reached the southern part of the perimeter, quickly taking up positions. The Japanese began a series of attacks throughout the entire night from all sides using machine guns, grenades, mortar and rifle fire. Smaller parties of Japanese were trying to infiltrate positions. It was a terrifying experience for the defenders who would dub it “guy fawkes night”. Many of the men had itchy fingers which led to tragic accidental casualties throughout the night. It was a pitch black night and the noises of the jungle and Japanese screaming stuff in english unnerved the allied forces. The Japanese had tossed a ton of stuff into the perimeter trying to get the allies to use up their own munitions in response. As a result the allied forces had 18 deaths and 27 wounded several of which were the result of friendly fire. The Japanese it seems to have around 50 deaths during the night.

Back over in the north, on June 30th, Captain Dexter was leading forward a number of patrols in preparation for an assault upon Duali. However as they advanced they ran into a Japanese ambush along the Bitoi track, thus canceling their planned assault. The next day, Brigadier Moten ordered Dexter’s exhausted men to move forward regardless. With some support of Beaufighters strafing the Japanese positions, the Australians charged straight through the enemy positions, and to their shock they found them abandoned. As Dexter recalled ‘We advanced through the Japanese position with fixed bayonets and searched the scrub on each side. Everywhere was evidence of a hasty evacuation, dropped equipment and personal rice bags, and evidence of extensive bomb damage. But of the Japs, no sign.’ Thus Dexter and his men captured the mouth of the Bitoi by early afternoon.

Shortly after the capture, Dexter made contact with MacKechnie who was busy expanding his perimeter northwards. By nightfall, PT boats led by Lt Commander Barry Atkins covered the landing of 11 landing craft full of reinforcements. The PT boats staffed nearby villages to cause a lot of ruckus, hoping to dissuade nearby Japanese from firing on the vulnerable landing craft. The reinforcements were mostly from B company who had failed to land during the third wave. On July 2nd, Moten began to pressure MacKechnie, stating he had to get his troops moving inland at once. Thus MacKechnie decided to leave C company to defend the perimeter while Lt Colonel Harold Taylor would lead the rest of the men towards Napier. Luckily for the men, 4 75mm pack howitzer m1 artillery guns had been unloaded that night with the reinforcements giving them ample firepower. The gun were positioned on the beach and immediately went to work shelling targets at the mouth of the Tabali River, Cape Dinga and the area between Duali and the Bito River’s southern arm.

On July the 3rd, the men now designated the Taylor Force accompanied by Dexter’s company were marching for Napier, but their march was a slow one as the jungles were thick and they were carrying heavy equipment. While this was occurring the 3rd battalions of the 102nd and 66th regiments were consolidating around Lake Salus looking to create a defensive position. The coastal area however proved to be too difficult to fortify, so they moved over the Tambu where they joined a SNLF platoon of the 5th Sasebo to make a position there.

At this point General Savige decided to send the Papuans north along the coast to keep pressuring the enemy’s retreat. By the 4th, Taylor Force had taken a position at Napier and were now under the direct command of Moten’s 17th brigade. Back over on the beaches at Nassau Bay a total of 1477 troops had been landed, thus securing the beachhead. Dexters company marched back over to Guadagasal taking a coastal route, getting themselves ready for a future assault against Mubo slated for July 7th. MacKechnie believed the loss of some of his landing craft had greatly delayed the entire operation, perhaps up to 3 weeks. He did not think he would be able to move artillery or large quantities of supplies further inland. He also did not think it was tactically sound to leave his base, as the Japanese proved to be quite a nuisance in the area. Orders from the top were demanding a artillery road be built, but his troops at the assembly area would probably run out of rations in a day or two and he had no native carriers on hand. In his words "To be very frank we have been in a very precarious position down here for several days and my sending the rifle troops inland was contrary to my own best judgment. Troops had gone inland stripped to the bone. Without heavy weapons and mortar and machine-gun ammunition. "Therefore, these troops who are up there now are in no position to embark upon an offensive mission until we are able to get food, ammunition and additional weapons up to them." In response to the situation, on July 6th, Moten ordered 1000 rations and 100 boy loads of ammunition…god you have to love the australians, boy-loads haha. Anyways this was to be dropped over Napier.

Moving over to the Solomons, Admiral Halsey had successfully occupied Rendova, Segi point, Viru Harbor and Wickham anchorage forcing the smaller number of Japanese to withdraw to their main base at Munda. Admiral Kusaka tossed a series of air strikes against the invaders, suffering horrible losses whereupon he had to request General Immamura reinforce him with the 21st air flotilla at Saipan and from the 6th air division.

For the battle of Munda, Admiral Halsey had assembled the largest air force ever assembled in the Solomon islands campaign. It was a force that was needed as the Japanese in Rabaul tossed every bomber that was available to try and thwart the US amphibious invasion. The June air battles had greatly depleted the Japanese air power, but they were not done. On July 1st the Japanese hit Kahili using 6 Vals and 34 Zeros. They were trying to knock out the 3rd battalion, 103rd infantry who were unloading at Poko plantation on the west coast of Rendova. However they were met by 20 P-40’s and F4Fs that ripped them to pieces taking down 3 Vals, 5 Zeros and losing 5 P-40’s in the process. Although the allies were scoring massively high success against the Japanese in ratios, by this point it reached 7 to 1, they were still unable to sustain round the clock 32 fighter or more CAP. To do this required a total of 96 operational aircraft and after 10 days of fighting in the skies over New Georgia the pilots were also becoming increasingly exhausted. Colonel Merrill Twining requested more P-38 Lightnings, the aircraft that had become the most comfortable fighter to those in the south pacific by this point. But Hap’s Arnold over in Washington was heavily committing forces for General Patton and Montgomery’s invasion of Sicily at the time so he had to deny this request. As Arnold stated back “every trained unit must be thrown against the German until he is beaten”. 

Regardless, with Rendova secured, General Hester was landing the bulk of his forces for the final push against Munda. The unloading process had been heavily hampered by poor planning and a failure to allocate adequate personnel for beach control and unloading duties however. To clear the new beachhead and distribute the combat stores, infantrymen were detailed to carry out the work. When transports carrying the next echelon arrived, many of the boats grounded offshore and had to be unloaded manually by troops wading ashore. On July 2nd, Admiral Kusaka coordinating with General Itahana formed a combined strike led by Major Endo Misao consisting of 18 Ki-21 bombers, 23 Ki-43’s and Ki-61s with 29 Zero escort. Unfortunately for the allies, Admiral Mitscher had recalled the Rendova patrol due to bad weather, so a total of 18 Ki-21 bombers came to the scene unmolested and hit the congested area around the harbor. The strike caused 200 or so casualties, mostly upon the 2nd battalion, 172nd, the 24th seabees, the 9th defense battalion and staff officers of various headquarters. The strike also knocked out a lot of equipment and supplies.

With the failure of the June air battles to hold back the allied invasion, Admiral Koga turned to the Navy for the task of providing new supplies to the defenders at Munda Point. The Tokyo Express was back in business, a convoy of 10 destroyers were sent to New Gerogia led by Rear Teruo Akiyama aboard his flagship Niizuki. His force was ordered to attack Rendova and he had with him the old Yubari, Yunagi, Mikazuki who would operate south of the Treasuries as a diversion, while Niizuki, Amagiri, Hatsuyuki, Nagatsuki, Satsuki, Mikazuki and Mochizuki would hit the allied shipping and shell the harbor. The Japanese destroyers were spotted right away, but bad weather prevented 3 American strike forces consisting of PBY’s and B-25’s from hitting the incoming enemy. In the meantime, Akiyama closed in on the southern tip of Rendova. She circled the island and opened fire on a point due west of the harbor. The bombardment was quite ineffective, but some allied PT boats rushed in to attack her which caused a wild 10 minute mini battle seeing 2 of them running aground.

On the ground, General Hester ordered the 1st battalion, 172nd regiment and A company of the 169th regiment now designated Southern Landing Group to land at Zanana beach. Led by General Wing on the afternoon of the 2nd they made a crossing over Blanche Channel using 16 landing crafts. With the support of Brigadier General Harold Barkers artillery they successfully formed a perimeter. Now the Japanese air and naval attacks were worrying Halsey. He expected the Japanese to launch a major counterlanding with substantial forces perhaps on the 3rd. Therefore he ordered Admiral Ainsworth to lay in wait off the west coast of Rendova for the enemy. However July the 3rd would not bring an enemy, this was because General Imamura and Admiral Kusaka agreed with the lack of air and naval forces on hand at this time they could not perform such a feat, to the disgust of General Sasaki who had assumed command over the defense for Munda on the 2nd. Sasaki was so adamant about landing reinforcements at around midnight on July 3rd he proposed violating orders to simply make a counter landing using the 13th regiment and Ota’s barges. He had a crazy idea to simply bring the vessels in and mix them with the American landing craft who were making rountrips to the mainland through the Honiavasa passage. He thought even if half his forces perished, the attack would be worth it. Ota objected to this on the grounds the barges would be needed for other transports scheduled for July 4th and 5th, apparently this made Sasaki visibly upset, who adjourned the meeting and left the room. Ota pushed Sasaki to write his plans down and submit them to Rabaul, which he did, and Rabaul squashed it immediately. 

On July 3rd the Japanese performed an unsuccessful fighter sweep over Rendova and the next day reconnaissance reported the island was secured by the Americans who had heavily reinforced it with anti aircraft guns and radar. They also reported landings on Zanana and that it looked like Rice Anchorage would be next, thus cutting off Japanese reinforcements from coming down the Munda trail from Bairoko. Imamura and Kusaka had to wait for an accumulation of forces to bring reinforcements to New Georgia; they had no intention of losing it like Guadalcanal. 4000 soldiers of the 13th and 45th regiments were earmarked for departure. Kusaka ordered Itahana to launch another combined strike, this time aimed at Roviana island. However the Japanese were intercepted by 32 F4F’s causing the loss of 6 Ki-21s, 3 Ki-43’s and a zero without a single loss for the Americans. This would be the fateful end of the joint air operations as Itahana needed to take his forces to help the Salamaua area. Luckily for Kusaka he received reinforcements in the form of the 201st Kokutai from the 25th flotilla which would allow him to gradually rebuild his air strength by mid july.

Meanwhile Admiral Turner had assigned 7 destroyer transports, 2 fast minesweepers and 4 Destroyers to carry the 1st raider battalion, the 3rd battalion, 145th infantry regiment and the 3rd battalion, 148th infantry regiment of the 37th division led by Colonel Liversedge into the Kula Gulf. Their escort cover was Ainsworth task group 36.1 consisting of the Cruisers Honolulu, St Louis, Helena and destroyers Nicholas, O’Bannon, Strong and Chevalier. They were also tasked with bombarding Vila and Bairoko. On July 4th, Ainsworth led the group up the slot while the Rear Admiral Teruo Akiyama’s Tokyo Express were on their way to Vila carrying 1300 troops of the 13th regiment towards Vila.

At around midnight Ainsworth entered Kula Gulf carefully avoiding the mindfield laid back in May. His force proceeded to shell Vila, but they failed to detect the Japanese who were heading south. The Japanese detected the Americans at 12:15 thanks to their brand new radar system; the 1-shiki 2-go radar which was outfitted on the Niizuki. The IJN were eager to test out the radar so they fastened it to the flagship of Destroyer squadron 3. Oh how the turn tables as they say. The radar indicated they were heavily outnumbered, so Akiyama decided to abort the mission, but before doing so he ordered 14 torpedoes to be launched at a range of 10 miles. The type 93 long lance torpedo remained the best weapons of the kind in the Pacific theater and one his destroyer Strong at 12:43 practically cutting her in two. Can’t stress it enough what an immense advantage Japan had over the Americans in terms of torpedo power during the first half of the war, hell if any of you play World of Warships, you know Japanese DD is base as hell. 

When the torpedo hit, the Japanese were already heading back up the Slot and Ainsworth thought he was being attacked by IJN submarines. Thus while Liversedge’s men were landing on the southside of the Pundokono River, Ainsworth dispatched destroyers O’Bannon and Chevalier to rescue the survivors of Strong. The Strong was settling fast off the Enogai inlet. When Chevalier and O’Bannon came to the scene picking up survivors a gun duel emerged between them and some batteries on Enogai. By 1:22am Chevalier had 239 men come aboard before her commander said it was time to go. His ship was getting battered by the batteries and he unfortunately was forced to ram the Strong to keep it from capsizing which ripped a 10 foot fash in Chevaliers bow. A near miss from one of Enogai’s guns had opened her seams aft and another shell knocked out her NO 3 gun mount. When Chevalier was pulling away from the Strong, breaking her in two in the process, 3 of Strong’s depth charges went off under Chevalier lifted the entire boat out of the water causing her to flood in forward sections, talk about bad luck.

Over in Rice Anchorage, despite the terrible stormy weather and some gunfire from Enogai, Turner ordered the transport group to clear the Gulf by 7am so they could quickly unload their cargo. 300 men of the 148th regiment landed further north at Kobukobu inlet because of the terrible weather. It would take them until July 7th to meet up with the main body. Though the USS Strong had been sunk, the Tokyo Express failed her run, thus Akiyama elected to bring the bulk of his shipment to Vila the following night, but this time he brought 10 destroyers; Niizuki, Suzukaze, Tanikaze, Mocizuki, Mikazuki, Hamakaze, Amagiri, Hacujuki, Nagacuki and Sacuki. Halsey got advance word of this and ordered Ainsworth to return to Kula Gulf to wait for the Japanese to show up. Halsey also reinforced him with destroyers Jenkins and Radford. Ainsworth went into this with a simple but ultimately flawed plan. He overestimated the capabilities of radar guided 6 inch guns against fast moving targets. On top of that he seemed to be totally ignorant of the IJN’s Type 93 Long Lance torpedo’s capabilities. His plan was to wait passively until radar detected the enemy than he would toss his cruisers at the enemy using their 6 inch guns, hoping to fire over 8,000 yards or so. He believed that was the effective Japanese torpedo range, why he believed this I do not know. For his destroyers, they would launch torpedoes at the enemy.

 

Akiyama’s Tokyo Express departed Buin after sundown divided into a covering force of 3 destroyers in the front and the main bulk behind them. Around midnight on July 6th, Ainsworth’s force were just northwest off New Georgia, entering the mouth of the Kula Gulf. The Japanese were also arriving to the Kula Gulf whereupon they detached the first transport unit to land 1600 troops. By 1:06am, Niizuki’s radar detected Ainsworth’s force, but this time Akiyama was prepared for a fight. Akiyama detached his second transport unit at 1:43am and 7 minutes later American radar picked up the Japanese. Ainsworth took his force in closer until the enemy was 7000 yards away. Then at 1:56am at around a range of 6800 yards the Americans Cruisers began to open fire. Akiyama quickly recalled the second transport unit before he engaged the enemy. Unluckily for Akiyama the Americans concentrated their fire upon the Niizuki which was pulverized quickly. She became a burning wreck before she was sunk by 6 inch shell fire taking Rear Admiral Akiyama’s life alongside 300 sailors. Within 20 minutes the Americans would fire 612 shells, 6 of which smashed the Niizuki.

 

Despite the loss of of their commander, the well drilled torpedo crews pulled off a salvo of 16 torpedoes at the American gun flashes. Ainsworth ignorant of the long lance range could do little to avoid it. The light cruiser USS Helena was the first to be struck, her bow was blown off virtually up to the number 2 turret, nearly cracking her in two as she sank taking 190 of her 1177 crew with her. St Louis was hit by a torpedo that fortunately did not detonate and another nearly missed Honolulu. The Japanese fled as fast as they could for Buin as Ainsworth directed his two remaining cruisers to shell the second transport unit. Of the four destroyers in this group, Amagiri escaped with minor damage, while Hatsuyuki was hit by 2 6inch shells, but luckily for her they were duds and she limped away. Nagatsuki was hit by a single 6 inch shell to her rear ship which would force her to run aground near Bambari Harbor. The next morning she would be destroyed by American aircraft.

At 3:30am, Ainsworth ordered his forces to return to Tulagi as he dispatched the Radford and O’Bannon to pick up survivors while Nicholas chased the fleeing Japanese. The Japanese dispatched Amagiri to pick up their survivors and she would be intercepted by Nicholas taking 4 hits before she made her retreat. While this was going on the First transport unit completed unloading its 1600 troops and bolted through the Blackett Strait and Kula Gulf. The Japanese had managed to land their reinforcements and sunk the USS Strong and Helena, so they considered it a tactical victory, though the loss of the Niizuki and her commander was terrible. The battle for New Georgia was nowhere near done.

The landings and early offensives were well on their way on New Georgia and the drive upon Lae was closing in. The Battle of Kula Gulf gave the Americans a bloody nose and now the Japanese had more forces at their disposal to try and dislodge the Americans from New Georgia.

- 84 - Pacific War - Invasion of New Georgia, June 27 - July 4, 1943

Last time we spoke about the extensive plans involved in Operation Cartwheel. The allies were crossing their T’s and dotting their I’s. MacArthur was getting closer to unleashing Operation Chronicle, the invasion of Woodlark and Kiriwina islands. MacArthur’s Navy, that being the 7th amphibious fleet are now prime and ready to go. Over in the Solomons, Admiral Halsey’s Operation Toenails likewise had finalized their plans for a full scale invasion of New Georgia. The invasion would consist of multiple amphibious assaults done by countless units all with important missions. It was to be a extraordinary complex operation that would showcase to the Japanese how far American production had come and just how doomed the empire of the rising sun was. In the words of a great wizard “The board is set, the pieces are moving. We come to it at last, the great battle of our time”

This episode is the Invasion of New Georgia

I do want to just start off with a bit of an apology. I am well aware the past few episodes have been extremely heavy on the planning rather than the doing as they say. Again this is the reality of the week by week schedule and this podcast as I hope all of you know follows the Youtube series almost to a T, well almost, I do like to wander off now and then. But today I assure you we are diving into the fray of battle. Ever since the conclusion of operation KE and the allied victory at the Bismarck Sea, the war in the South Pacific had gotten a bit more quiet, but certainly tense. Both sides were looking at another, expecting a major offensive to kick off at any moment. But it would be the allies who would kick off everything by unleashing the start of Operation Cartwheel. The opening shots of Cartwheel would begin with the invasion of Woodlark and Kiriwana islands just off the southeast coast of New Guinea and due south of New Britain.

Colonel MacKechnie’s 162nd regiment continued to prepare their Nassau bay landings just 11 miles south of Salamaua. Ever since April of that year their 1st battalion had been carrying intensive amphibious training at Morobe Harbor. They were being reinforced with the 532nd engineer shore regiment, 542nd engineer amphibian regiment, the 592nd engineer boat regiment under Brigadier William Heavey and with a Papuan infantry battalion who had marched to Buso by mid june. Under orders not to proceed any further north, the spent their time carrying out long-range patrols, gaining valuable intelligence on the enemy. From their intelligence, MacKechnie believed there were about 75 Japanese near the mouth of the Bitoi river, an outpost or two along the beach at Nassau Bay and about 300 Japanese on Cape Dinga which also held an outpost. MacKechnie decided to use Mageri point as a staging base, which held an excellent beach 12 miles north of Morobe with good cover for their landing crafts.They had with them 2 LCMS, 2 captured Japanese barges and 29 Higgens boats. To further augment them, 4 PT boats were assigned to help transport the men, around 150 of them from Morobe.

In the meantime, Brigadier Moten planned to send Captain Dexter’s D company who had just achieved an incredible victory at Lababia ridge where they repelled a Japanese force 10 times their size to march to the Bitoi rivers mouth to divert Japanese attention away from Nassau bay. On top of this one of their platoon’s led by Lt Dave Burke would guide the Americans to the landing beach. Now operation Chronicle was expected to go unopposed, though Krueger did not tell his men that. The Woodlark group consisted of Colonel Cunningham’s 112th cavalry regiment while Kiriwina would receive Colonel Herndon’s 158th regiment. Admiral Barbey’s 7th Amphibious force with the support of Admiral Carpender’s 7th fleet would transport them.

On June the 20th, Krueger set up the 6th Army HQ at Milne Bay. The 6th Army was codenamed the Alamo Force as it assumed control of the majority of US Army units involved in operation Cartwheel. General Kruegers command was actually a bit awkward. Instead of operations being conducted directly by the 6th army, the Alamo force, which was purely an operational entity, basically administration, was in charge…and it was directly under the control of Douglas MacArthur. So as you can imagine for Krueger …well it was like having two of the same hat kind of? In his own words "the inherent difficulties faced by my dual headquarters in planning and administration were aggravated by the command setup, which was a novel one to say the least." Thus Alamo force was on New Guinea while the main body of the 6th Army HQ, the real one was in Brisbane until February 1944, when upon they were merged together. Yes this was a sneaky maneuver by MacArthur to seize control. Ever since the Buna campaign, MacArthur was increasingly unhappy with having to depend primarily on Australian troops. Although on the surface he look to be in a great harmonious relationship with Blamey, in truth MacArthur was extremely critical of the man and the Australians in general. Alamo Force was his way of wedging himself into the chief role for planning and conducting the later stages of the war, thus bypassing Blamey as the allied ground force commander. 

To kick off the operation, Krueger sent advance parties of the regiment groups to secure beachheads in the two islands. At 4pm on June 22nd an advance party of the 112th cavalry regiment led by Major McMains left Milne Bay aboard the destroyer transports Humphreys and Brooks bound for Woodlark. They arrived in the dead of night at Guasopa and unloaded 200 men using 6 Landing crafts. The destroyer transport departed by 4am for Milne Bay. It turned out a Australian coastwatcher, not having been informed of the landing nearly attacked the force with his locally recruited guerrillas. But upon hearing the accents of the troops he quickly realized them to be friend and not foe. The advance party went to work performing reconnaissance, establishing defenses and facilities for the incoming invasion force and clearly marked the beaches for them to land. The next day the 158th infantry regiments advance party led by Lt COlonel FLoyd Powell departed Milne Bay at 6:10 aboard the two destroyer transports. They were accompanied by a detachment of the 59th combat engineer company. They arrived to Kiriwina around midnight, taking their landing craft through a small channel that passed through a reef to the beach at Losuia, code named Red Beach. Their unloading was quite slow due to lack of experience, bringing them the threat of aerial attack by the enemy. Thus the ships were forced to depart partially loaded. 

On June 25th Operation Chronicle officially began. 2600 troops of Colonel Cunninham’s Woodlark force departed Townsville Australia aboard 6 Landing ships, a subchaser and the destroyers Bagley and Henley. As the Woodlark Force slowly and stealthily made its way, 2250 troops of Colonel Herndon’s Kiriwina Force departed Milne Bay aboard 12 Landing crafts, 2 coastal transports and were escorted by Admiral Brabeys destroyers. They successfully landed at Losuia beach at dawn on June 30th completely unopposed and the unloaded process was quite slow. Around the same time, Colonel Cunninghams force landed at Woodlark, also unopposed, but their unloading went much faster. The problem for the team at Kiriwina was an extremely spiny necklace of coral. The landing craft had grounded several hundred yards short of the beach, with only a single one passing over the sandbar to land offshore. Heavy rain and a low tide were hampering the vehicles and thus making it a nightmare. It was the complete opposite story over at woodlark. Their supplies were already loaded onto trucks which drove straight off the landing crafts allowing for an efficient unloading process so the vessels could depart before enemy air attacks might occur.

Meanwhile, B-25’s of the US 5th air force bombed Japanese strong points along the Bitoi river as A-20 Bostons hit supply dumps on the southern side of Nassau Bay on June 29th. The amphibious landing force known as MacKechnie Force departed Mort Bay at dusk on the 29th. PT boats of the 7th fleet took around 210 men of Lt Colonel Harold Taylors 1st battalion, 162nd infantry regiment while 29 of the captured Japanese barges took the 770 men of 2nd Engineer special brigade and two mechanized landing craft took the 532nd engineer boat and shore regiment to Mageri point. They landed in 3 waves and just like woodlark and Kiriwina, it went unopposed seeing all 770 safely landed at Nassau bay. The Japanese defending the immediate area were just 6 guys at an observation post, and offered only a few shouts in defiance before they fled into the jungle. 

On June 30th the men went to work clearing up the beach to create a defensive perimeter, while some units of C company marched south to link up with the incoming papuan infantry battalion. Some other patrols ran into Japanese and were turned away near the bitcoin river. Upon receiving news of the landing, General Nakano ordered the 3rd regiment of the 66th battalion to march south from Salamaua. However the Australians were also applying pressure near Bobdubi so the 3rd regiment could only carry out limited attacks on the allied forces around Nassau bay, before they would perform delaying actions to allow the Nassau garrison to withdraw towards lake salus. The Papuan battalion began attacking the rear of the Japanese 3rd regiment of the 102nd battalion around Cape Dinga causing some casualties when they stormed a Japanese bunker. Nassau Bay would see some minor Japanese air attacks but for the most part things were going smoothly, allowing the seabees to work on the new facilities and airstrips for Woodlark and Kiriwina. Now thats it for MacArthurs half, time to go over to the Solomons.

As you will remember, Admiral Haley’s plan for New Georgia consisted of 5 different landings scattered about the island. Four of these landings were to occur on June 30th. These landings were 1) Wickham Anchorage on the southeast coast of Vangunu 2) Segi Point on the southeastern tip of New Georgia 3) Viru harbor on the southwest coast of New Georgia just a few miles up from Segi and 4) Rendova Harbor on Rendova island just across the Blanche channel from Munda. As a preliminary, Halsey sought to land some reconnaissance teams. The first one to arrive was at Segi point on June 14th consisting of units from the 47th seabees tossed over by PBY’s. They began constructing landing sites for heavy equipment to come over. The next saw units go over to Viru Harbor, then Oloana Bay on Vangunu just a bit west of Wickham Anchorage, another at Rendava harbor and a last one at Rice anchorage. These teams all prepared the way for the future landing teams. However all did not go smoothly, for on June 16th over at Segi Point a dozen scouts being led by the New Zealand coastwatcher Donald Kennedy unsuccessfully ambushed a Japanese patrol. Kennedy had established a defense zone around the village of Segi used local native forces who were using scavenged weapons and they often tried to ambush and kill small Japanese patrols. This patrol they had stumbled upon was a platoon from the 4th company, 229th regiment operating around Viru harbor. They didnt manage to kill any of the Japanese, but instead alerted Colonel Sasaki of allied activity near Segi point and Viru harbor. Sasaki responded by ordered Major Hara Masao the new commander of the 1st battalion with his 3rd company and a machine gun platoon over to Viru harbor the following night. His orders read “settle things”. Luckily Hara had no idea where exactly Kennedy and his guys were so they would have difficulty finding them, but this did mean Japanese activity in the area increased. On June 20th Kennedy made an inaccurate report indicating the Japanese had landed troops in Nono Lagoon prompting Admiral Turner to react. That night Turner sent Companies O and P of Colonel Currins 4th raiders to occupy Segi Point with companies A and D of the 103rd regiment following them the next day. This meant Kennedy and his men were saved, but it also alerted the Japanese of the incoming offensive as allied destroyer transports were spotted around Wickham. This prompted Admiral Kusaka to put the Southeast Fleet on high alert, but further reconnaissance failed to find anything, thus by the 27th the IJN relaxed. This was also partly due to the fact that the IJN believed no invasions would come until late July or August.

It would only be Lt General Sasaki who believed the allies might invade as early as late June, so he had set to work preparing New Georgia’s defenses. Sasaki did not have much time, nor much capable labor as there was a large case of malaria going around. Added to this materials and equipment were hard to come by as supply missions were failing to arrive on time. The terrain on the island was quite an obstacle also. The Japanese dug into coral on the south side of their airfield and establishing communication lines towards the east. In the northern sector Sasaki placed 4 Kure 6th 14cm guns at Enogai point, but Bairoko had basically nothing. East of the airfield practically no defense existed. Sasaki managed at the last minute to construct some gun emplacements at Bairoko ingeniously using blocks of coral, something that the Japanese would really build up in later island warfare. To establish a main line east of the airfield he had the men build extremely strong bunkers to face frontal assaults across the Munda Bar. Communications would be a major issue as all they had to work with was a motor vehicle road that ran along the beach to Lambete and 1000 meters of completed road between the southeast Detachment HQ and 229th infantry HQ. Other than that there were no roads, just some trails which Sasaki described “that turned into slush ponds after rain”. To keep in contact with the troops spread everywhere, Sasaki requested they use an underground cable, but it seems he never got it. Sasaki was forced to spread his men in multiple places seeing company sized units in exposed locations at Wickham Anchorage, Viru harbor and Rendova harbor. These units would have been better used at places like ENogai, Bairoko and Ilangana.

To help with the landings, General Kenney ordered the 5th air force  to launch a heavy raid against Rabaul while Admiral Merrill’s cruisers escorted minelayers up to the Shortland islands to mine the southern entrance to Buin. Merrill’s cruisers also took the time to bombard Faisi, Ballale and the Poporang islands while he dispatched some destroyers to hit Vila. Early on june the 30th B-24’s and B-17s from AirSols hit Kahili and further raids would be made against Munda and Vila throughout the day. 

The night of June 29th was a very stormy one hindering the AirSols and 5th air forces abilities and even Merrill’s ships had difficulty carrying out their tasks. Admirals Turner and Fort departed from Guadalcanal, Tulagi and the Russels to land the forces. Two groups of infantry units code named“barracudas”; 2 companies of the 172nd regiment enroute for Rendova and Companies A and B of the 169th regiment and 1st Commando Fiji Guerillas enroute for Honiavasa went ahead of Turner aboard the faster transports Ward, Lang, Talbot and Zane. They were going to seize Rendova Harbor’s beaches and the Honiavasa passage. The convoys continued their voyage to New Georgia in the early hours of the 30th facing no difficulties and would reach their jump off points in the early morning. The Barracuda groups arrived at 2:25an, successfully landing the first infantry group at Baraulu, Honiavasa and the Sasevele islands securing their staging base. The Rendova group however got a bit lost, leading to a bit of disorder, but they landed nonetheless. 

By 6am the 43rd division begun its landing which was described by the US Marine corps official history as “hurried and having the appearance of a regatta rather than a coordinated landing, it was chaotic in the extreme”. Troops from the 103rd field artillery battalion, Marines from the 9th defense battalion and Seabees from the 24th naval construction battalion secured the beach even though Japanese sniper of the 1st rifle company, Kure 6th and 7th company, 229th regiment were making pot shots at them. There was also the appearance of Japanese Betty’s overhead who circled the landing zone, but did not attack. The Japanese reported back to their commanders “that due to the tenacious interference by enemy fighter planes, a decisive blow could not be struck against the enemy landing convoy. And that the landings were an absolutely miraculous and speedy disembarkation of the enemy”. I believe this showcases another major disparity between the allies and the Japanese, that of amphibious assaults. The allies and Japanese were on par at the beginning of the conflict, neither side understood the science per say, but particularly the American began to really study how it to do it, designing and employing multiple different vehicles to help in its efforts. Meanwhile the Japanese would do little to improve their methodology, thus from their perspective to see how the allies were doing it in mid to late 1943 probably looked like magic. General Hesters 2nd battalion, 172nd regiment quickly established a defensive perimeter around the beachhead. His men had a rough time of digging in due to the ground being heavily waterlogged, nothing like a wet foxhole eh?

Outnumbered and taken by surprise, the Japanese were gradually pushed into the interior suffering heavy casualties in the process. They initially assembled in a coconut plantation behind the initial landing beach known as the Levers plantation. They took up a position hoping to launch a counter attack on the American perimeter. However a week of heavy rain left them fighting miserably in knee deep water and eventually they could not bare it any longer so they withdrew further into the hinterland. Troops of the 172nd regiment pursued many of them shooting down several snipers and machine gun positions as they advanced towards the Pengui river. Near the river the Japanese tried to remain firm meeting the Americans with all they had, but the US mortars rained hell upon them eventually forcing them into a rout. The Japanese would scatter, many aboard makeshift rafts trying to head for the mainland. These efforts would be in vain however as American patrol vessels caught many of them.

Over on Baanga island and around Munda Japanese artillery began opening up on 4 US destroyers sailing through the Blanche channel. The USS Gwin was hit, killing 3 and wounded 7 before the USS Farenholt and Buchanan began to return fire upon the batteries neutralizing them. Just before noon a force of 27 Zeros of the 11th air fleet performed a fighter sweep over the beachhead, but it resulted in nothing more than a few delays and the loss of 4 Zeros to allied fighters. 6000 Americans were soon landed on Rendova. It was grueling work to create the beach head, in the words of the Seabees leader, Commander Roy Whittaker about the conditions his men had to work in “They ceased to look like men; they looked like slimy frogs working in some prehistoric ooze. As they sank to their knees they discarded their clothes. They slung water out of their eyes, cussed their mud-slickened hands, and somehow kept the stuff rolling ashore.” Indeed it was a hell of a time. Tons of bulky B rations, hundreds of barrels of petroleum, thousands of barrack bags filled with personnel items were piled all over the beach. People don’t often ever think about the logistics of war, its usually seen as the unsexy stuff, but it was of critical importance as we have seen countless times in this series. The Seabees were missing heavy bulldozers, army engineers, adequate medical personnel, military police, because yes boys will be boys and a lot of men were stealing stuff. It turned out the reason for a lot of the lack was because Turner loaded the operation for an unopposed landing rather than an offensive one. As reported by Lt COlonel McNenny “equipment and stores carried in the New Georgia operation were excessive. It appears the forward base must be considered as an assembly area for launching the assault.” Colonel George W. McHenry wrote in his notes, “Believe too much gear for initial landing. Stress what [is] necessary to fight and eat. Bring other up after secure.” By 3pm, most of Turners stuff was unloaded and his vessels were preparing their withdrawal.

Admiral Kusaka and General Imamura had already been alarmed by the landings at Nassau Bay, and were shocked to find out at 6:50 Rendova was seeing landings. In response they unleashed an air strike at around 3:45pm. Led by Lt Commander Nakamura Genzo, 26 Betty’s and 24 Zeros came in to attack the departing convoy. they were intercepted by 48 allied aircraft made up of F4U Corsairs and F6F Hellcats and were met with heavy anti aircraft fire. The Japanese lost a 10 Zeros and 19th Bettys in the mayhem. However a single Betty was able to release a torpedo which struck Turners flagship McCawley, killing 15 sailors and wounding 8 others. Turner luckily survived the hit and transferred his flag to Farenholt. Rear Admiral Theodore Wilkinson remained aboard the McCawley as she began being towed by the cargo ship Libra. Later in the afternoon, another Japanese wave of 21 Zeros, 9 Vals and 13 F1M Floatplanes showed up attacking the convoy. The McCawley was strafed, but managed to fight back with their anti aircraft guns shooting 3 planes down. By 6:60pm it seemed the McCawley was going to sink so Admiral Wilkinson ordered her abandoned. Later on at 8:22 a PT boat would actually misidentify the doomed McCawley as an enemy ship and torpedoed her twice, sinking her. The poor fleet tug Pawnee who was tugging her at the time narrowly was hit as well. At 5:20, 21 Zeros and 9 Vals would launch their last attack, but it was extremely disorderly and amounted to nothing. By the end of the day, AirSols had destroyed nearly a quarter of Kusaka’s air strength while only losing 17 fighters in the process. The losses were so grave, Kusaka was forced to ask Imamura to commit the 6th air division to help out in the future. When the IJN is asking the IJA for help, you know the shit has really hit the fan.

Now over to the east, Admiral Fort was performing his 3 simultaneous landings. At Wickham Anchorage, Fort was going to land Companies N and Q of the 4th raiders along with Lt Colonel Lester Browns 2nd battalion, 103rd regiment. They would touch down on a 500 yard strip of beach at Olona Bay. The 4th raiders would lead the charge heading their in the first destroyer transports, but mother nature was cruel that day leading to 6 Higgins boats getting wrecked and seeing Raiders scattered all over the area. One platoon got stranded on a reef 7 miles west of the landing point, not fun at all. Brown’s landing craft infantry meanwhile had no difficulty in landing on the marked beach. After reuniting with the scattered Raiders, Brown learnt there were enemy bases at Kearuku Village and Vuru. In response to this he sent Company E of the Raiders to hit Vuru while the bulk of his forces would capture Kearuku. The advance was slowed by rain, allowing Colonel Sasaki to send word to his men over at Wickham to withdraw to the northern coast of New Georgia as they were outnumbered and outgunned. However there was no way for them to do this as their barges were scattered in the Marovo Lagoon. Thus the Japanese found themselves under fire from the north side of the Kairuku river and by nightfall were being pushed towards Segi Point where their artillery was set up. The men defending Vuru had it worse and were easily scattered by E Company.

The next day the Japanese began unleashing their artillery, prompting Brown to request air and naval support to allow his men to hit Segi. However the support would only be able to come on July 3rd and by that time the Japanese had managed to escape. When July 3rd came, some US destroyers and 18 Dauntless dive bombers bombed Segi point. When Browns troops went in they killed 7 dazed Japanese and captured one. Because of the preemptive capture of Segi, the plans had to change in regards to Viru harbor. On the morning of june 28th, Colonel Curren ordered a single company to use rubber boats and go up the Choi river all the way to the western end of Nono Lagoon. From there the Raiders would march overland to hit the Japanese bivouacs at Tombe and Tetemara, hoping to link up with B company of the 103rd regiment. But now with Segi point taken, Currin instead left with his two companies to land at a village just a bit west of Nono Lagoon. However along the Choi river they would run into Japanese patrols, delaying them heavily. By june 30th, some of Forts destroyers would enter Viru Harbor expecting to find Currins Raiders, only to be met with 3 inch field gun fire from the Japanese at Tetemara. The destroyers left in haste and landed a company at Segi point to help the Raiders out. Currin that morning split his forces, sending P company to attack Tombe while the rest would circle west of the harbor, cross the mango river and attack Tetemara.

After marching through endless swamps, by July 1st Currin and his men were prepared to attack, but Sasaki had also decided to order the withdrawal of forces at Viru who were now marching overland towards Munda. At 8:45 the Raiders stormed Tombe, overwhelming the few defenders there. 15 minutes later, 17 Dauntless began bombing Tetemara disrupting Japanese artillery crews. An hour later the Japanese artillery opened fire against the raiders, but they fought through the rain of shells and machine gun bullets. Taking the Japanese machine gun nests caused heavy casualties. At 4pm Currin ordered a final push, seeing Tetemara taken after 30 minutes. Major Hara alongside 160 Japanese would manage to escape into the jungle, heading for Munda. Though the eastern landings saw some heavy resistance, all of the objectives were met.

The allies' successful amphibious assaults proved how far they had come and the Japanese could only look on in wonder at the marvel it was. Now the allies would keep pressing further and further north, one island at a time until the Solomons and New Guinea were liberated.

- 83 - Pacific War - Battle of Lababia Ridge, June 20-27, 1943

Last time we spoke about operation Cartwheel, developments in Green hell and some new adventures in Burma. General Douglas MacArthur had his work cut out for him as he developed his original Elkton plan into what would become Operation Cartwheel. Alongside the US Navy, MacArthur set out the blueprints for seizing parts of New Guinea and the Solomons before taking the ultimate prize that was Rabaul. The Japanese meanwhile extended their efforts to hammer allied airbases in the south pacific with lackluster results. Over on New Guinea the allied forces were drawing closer to seizing Lau, by using Salamaua as a distraction. Over in the Burma front, the disastrous Arakan campaign had resulted in some shuffling of leadership and now the Auk was working with General Slim to see if they could prepare the Indian Army for another go at the Japanese. And today we are going to be venturing back into all of these stories.

Last time we were speaking about Operation Cartwheel and part of phase one for Admiral Halsey in the Solomons was to move north from Guadalcanal to hit New Georgia code named Operation Toenails. Halsey planned to perform four simultaneous landings. One was directed at Wickham Anchorage by the 2nd battalion, 103rd regiment plus two companies from the 4th raider battalion to be led by Lt Colonel Lester Brown. Wickham would become a new landing craft layover base. A second landing would be made at Segi Point by Companies O and P of the 4th Raider battalion and Companies A and D of the 103rd regiment would garrison Segi point and its airfield afterwards. Another landing would be made at Viru Harbor by Company B of the 103rd regiment for its small craft base. And a final landing would be made at Rendova Harbor by the 172nd regiment and 24th naval construction battalion Seabees which would become a stage for further troops coming over to New Georgia before an assault on Munda was made.

The 43rd infantry division led by Major General John Hester were going to take the lead against Munda. The 43rd were actually a national guard division from Connecticut, Maine, Rhode island and Vermont who were mobilized and reorganized as a “triangular” division. This meant they were going to be 3 regiments rather than 4. They would be brought up to strength, but in reality the only real experience they by this point was some unopposed landings on the Russell islands early in 1943. They had several months to prepare for the campaign. Hester got the men to construct pill boxes modeled after the Japanese one’s found on Guadalcanal for training exercises. However the terrain found on Guadalcanal or on the Russell Islands did not really bear much resemblance to that of New Georgia. In April 1943, the 14th corps arranged for the 147th regiment, veterans of the Guadalcanal campaign who had chased the Japanese west during Operation KE to conduct several training exercises with the 43rd division. However as noted by many of the men in the regiment the terrain was not very similar to what was expected on New Georgia hampering the training. By mid june the 103rd infantry and the 169th infantry also began training exercises on Guadalcanal using landing craft.

Now you probably noticed in my listening there was mention of the 4th raiders. Two new Raider battalions were entering the fray; the 3rd Raiders led by Lt Colonel Harry Liversedge were coming over fresh from Samoa; and the 4th Raiders led by Lt Colonel James Roosevelt from Camp Pendleton of California. And yes you are probably wondering, James Roosevelt II was the eldest son of FDR. Since 1936 he had been serving as his fathers military aide, under the commission of a captain in the Marine Corps Reserve. When the war broke out in 1939 he entered active duty and starting in April of 1941 FDR sent him on a secret mission. James traveled around the world on a diplomatic mission to assure other governments that the US would soon join the war despite the official neutrality stance. He met with Chiang Kai-shek in China, King Farouk of Egypt, King George of Greece, Sir Winston CHurchill of Britain and such. After the attack on Pearl Harbor he sat right beside his father as he gave the legendary Day of Infamy speech, and soon he requested an active combat assignment. He was transferred to the Marine Raiders by January of 1942 and became the 2nd in command of the 2nd Raiders under Carlson. He took part in the Makin Island Raid in August of 1942 where he earned a Navy Cross. He had some health issues, such as flat feet, and got the special privilege of being allowed to wear sneakers while the other Marines wore boots.

On March 15th the 4 Raider battalions were reorganized as the 1st Raider regiment, stationed at Espiritu Santo with Liversedge as their commander and Carlson executive officer. Carlson infused his fire team and squad models into the raiders, while Edson molded them into a highly trained, lightly equipped force who could accomplish special missions or fill a line battalion on the fly. The 1st Raider Regiment was no guerilla outfit, though it felt like that initially. For Operation Toenails, Halsey assigned both the 1st Raiders led by Colonel Griffith and the 4th Raiders led by Lt Colonel Michael Currin, supported by the 9th defense battalion which was carrying a 155mm gun units and light tank platoon. The Navy was also sending the legendary Seabees; Acorn 7, the 24th and a single section of the 20th naval construction battalions. It can’t be said enough how much the Seabee’s brought to the table in the Pacific. During the war theSeabee's would receive 5 Navy Crosses, 33 Silver Stars and over 2000 Purple Hearts alongside numerous citations and commendations. They performed legendary deeds in the Atlantic and Pacific creating over 400 advanced bases along the 5 figurative roads to victory.

 

Lastly and quite interesting to note, the Americans would have a unique commando units of 130 Fijians known as the 1st Commando Fiji Guerillas. When the Pacific War broke out, Japan had seized numerous territory going as far south as the Solomon islands getting just 8 hours flight time away from places like Fiji. At this time Britain was too preoccupied with the Atlantic and America was scrambling to recover from Pearl Harbor. Fiji was in a critical position and for several months while the US was organizing her forces so was Fiji. Fiji possessed 2 good harbors and 2 airfields and her position on earth put her smack dab on the way between America and Australia / New Zealand. The allies knew the Japanese would love to take such a territory and thus she needed defense. Small numbers of troops were garrisoning Fiji, many from New Zealand, but she had little to spare as she became heavily committed to Africa and the Middle East. Thus the Americans came to Fiji to relieve the New Zealanders and they helped expand Fiji’s forces. The result were commando units who proved themselves uniquely equipped for combat on pacific islands like the solomons. For New Georgia the Fiji guerillas were tasked with locating enemy soldiers scattered about the island.

The eastern landing force consisted of the 1st and 2nd battalions of the 103rd regiment alongside the 4 raider battalion to be led by Colonel Daniel Hundley. Their job was to secure the lines of communication to Rendova directly across from Munda. The Western Landing Force consisted of the 172nd and 169th Regiments; 3rd Battalion, 103rd Regiment; 9th Marine Defense Battalion; 24th Naval Construction Battalion (Seabees) and 1st Commando Fiji Guerrillas, to be led by General Hester. They had the initial mission of securing the island of Rendova and afterwards the 3 islets in the Blanche Channel opposite of Munda. For the islets it would be the job of Companies A and B, 169th Regiment; and 1st Commando Fiji Guerillas. Once all of that was done, the 172nd and 169th regiments led by Brigadier General Leonard Wing would advance to Zanana through the Honiavasa passage, then take a overland route over the Barike River for the final drive upon Munda supported by destroyer bombardment. Hester also planned to use the 3rd battalion, 103rd regiment to hook around Munda’s from the west coast.

For all of these amphibious landings, Admiral Turner was in charge with his task force 31. He divided his forces into two groups; the Western Force under his personal command which would make the Rendova landings; and the Eastern Force led by Rear Admiral George Fort would perform the landings at Wickham, Segi Point and Viru Harbor. For the Rendova harbor landing, Turner employed 4 Attack transports and 2 Aka’s; during WW2 Aka’s referred to merchant ships that were modified for combat use. These took the 172nd regiment and 24th seabees over on June 30th, while Turners larger landing craft, LST’s (landing ship tank), LCT’s (Landing craft tank) and LCI’s (landing craft infantry) would move Hesters initial units over the next few days.

The Amphibious forces would be covered by Halsey’s Task Force 36 constituting of forces that had previously been under the command of Admirals Ainsworth and Merrill, destroyers, cruisers, some battleships and a few carriers. Merrill would help the landings by performing a bombardment of the Shortland islands as minelayers created minefields across the southern entrance to Bougainville, and a smaller detachment of destroyers hit Vila as a diversion. Ainsworth would get himself into position in the seas around Rendova while Admiral Fitch would grant the operation a total of 1182 aircraft, including 626 from Admiral Mitschers Airsols as cover. To gain air supremacy, 17 air missions were assigned such as PBY crews for rescue operations and last minute supply drops over New Georgia. AirSols aircraft would be assigned to New Georgia missions with a few SBDS set aside for Russell operations. Fitch also went ahead and created the New Georgia Air force commanded by General Mulcahy who would direct missions from the ground.

Closing in on Operation Toenails, Halsey and Turner also decided to add a last minute landing directed at Rice Anchorage on the Kula Gulf. Designated Northern Landing Group, the landing was to be performed by the 3rd battalions, of the 145th and 148th regiments alongside the 1st raider battalion led by Colonel Harry Liversedge. This would occur on July the 4th to create a base from which the allies could launch an attack against the Enogai inlet and Bairoko harbor. By seizing these the allies could interdict Japanese supply lines and prevent reinforcement efforts for Munda. Now that is all for the plans for the Solomons, but Operation Cartwheel had other plans over on New Guinea being handled by General Douglas MacArthur and Kreuger, code named Operation Chronicle, the invasion of the Woodlark and Kiriwina islands.

The two Trobriand islands held airfields and were only 125 miles from New Britain and 200 miles from Bougainville. Capturing them would allow the allies to launch bombers with fighter escort to hit Rabaul, Kavieng and the northern solomons. It was also a great opportunity to test what was colloquially known as “MacArthur’s Navy”, officially known as the 7th amphibious force. Now Lt General Krueger had sent reconnaissance missions to the islands which indicated there were no Japanese present on them in May. Nonetheless he instructed the men to prepare for a fight and at the least to expect aerial attacks when they approached them. Kruegers plan of attack was simplistic, Colonel Julian Cunningham would lead the Woodlark force. This consisted of the 112th Cavalry Regiment; 134th Field Artillery Battalion; and 12th Defense Battalion. Also, the 20th and 60th Naval Construction Battalions and ARGUS 1. They would depart Townsville Australia on June 25th and land on Woodlark by June 30th. The Kiriwina Force would be led by Colonel Prugh Herndon consisting of the  158th Regiment; and 148th Field Artillery Battalion. They would depart from Milne Bay on June 30th and quickly land at Kiriwina that same day. To get them to the beaches, Admiral Barbey would have 4 destroyer transports, the Gilmber, Sands, Humphrey and Brooks alongside 6 LSTS, a subchaser 7 mechanized landing craft, 2 small coastal transports and a survey ship, a real hodge podge. Escorting them would be Barbey’s task force 76 consisting of the destroyers Mugford, Bagley, Conyngham, Henley and helm along with Carpenders task force 74 consisting of cruisers Australia and Jobart with destroyers Arunta and Warramunga. For aerial support they had multiple squadrons from Australian Wing 73 operating off Goodenough island.

Now on the grounds of New Guinea in mid June, Generals Savige, Herring, Berryman and Colonels Archibald MacKechnie met with Brigadier Moten to hear about his plans for the 17th brigade’s salamaua offensive. Moten laid out a 5 phase plan, phase 1 consisted of the 1st Battalion, 162nd Regiment creating a beach head at Nassau Bay, with the support of a company from the 2/6th battalion. Phase 2 would see the 2/6th reinforced by a company of the 2/5th who would capture Observation Hill and a ridge between Bui Savella and Kitchen Creeks. From there they would be able to move through Mubo Valley to Archway while American forces captured Bitoi ridge. Phase 3 would see the capture of Green Hill and the Pimple by American forces and some of the 2/6th. From there they could advance towards Komaitum and Lokanu. Phase 4 would see the 2/5th advance from Mubo through the 2/6th position to occupy Mount Tambu, linking up with the 15th brigade at Komiatum. Lastly Phase 5 would see the capture of Lokanu and Boisi, clearing the enemy away from the Francisco river area. The plan looked good to all present. But nothing was mentioned about the capture of Lae, nor the critical fact, that Salamaua needed to fall prior to Lae, lest they all lose the element of surprise for Operation Postern. This was done for security reasons, it all had to be held under wraps, but despite this General Savige remained convinced he had to capture Salamaua as soon as possible. His subordinate, Brigadier Moten was aware of the grand plan created by Blamey.

Yet while all of these allied commanders were planning, a war was still afoot and the Japanese tossed a counter offensive on the night of June 20th. The Japanese commanders had determined in late May that they needed to dislodge the Australians from Lababia Ridge. General Nakano had brought forward the 1500 men of 1st and 2nd Battalions of the 66th regiment. He concealed their movements by ordered heavy airstrikes and ordered the men to make no fires. This also allowed the exhausted 102nd infantry regiment to rotate back a bit as they had been fighting the Australians ever since the battle of Wau. On the 20th, Nakano began sending patrols made up of the 66th with a few guides from the 102nd who probed the Australian position on Lababia ridge, at that time being held by just 80 men. The Japanese patrols defused many booby traps the Australians laid out for them, made up of piano wire attached to hand grenades. However the Japanese were not too familiar with the Australian hand grenade, so instead of pocketing them to use against the enemy they simply left them. Some sporadic skirmishes occurred that day alongside some bombing missions aimed at Guadagasal, Mat Mat and the Mubo Valley. 83 Japanese aircraft caused some casualties and damage against the 2/6th and spooked a ton of native carriers. The next day the Australians would be searching for native carriers who fled, losing around 578 of them for over 3 days. This greatly delayed the movement of rations, ammunition and other supplies.

On the morning of June 21st, the 1st battalion of Araki, guided by some men of the 102nd regiment, began advancing around the eastern flank of the Australian position on Lababia, getting into position for a dawn attack set for the following day. Behind them was the 2nd battalion who were doing a similar maneuver but on the Australians left flank. The Japanese were extremely careful as they advanced having learnt bitter lessons throughout the war about how much the Australians liked to hang grenades attached to piano wire just about anywhere one would think to walk. Oh and it was not limited to fragment grenades, they hooked up thermite grenades, cans of petrol and other goodies. Now they were going to be attacking 80 men as I said, which were being led by Captain Walter Dexter’s D company. He had two platoons in a forward position on the Jap track and two others to the back guarding his HQ. Further north he set up listening posts to watch for enemy activity around the Pimple.

Dexter figured he was holding a decent enough position going on to say ”if you’ve got to fight them you’ve got to see them’. Around noon Australian patrols began to notice signs of Japanese activity along the track towards the observation post just a bit due east along the ridge. At 7:30 the telephone line to that observation post was suddenly cut and the Japanese could be seen approaching. The Australians went to work setting off booby traps that had been rigged up as early warning devices and a small firefight emerged. Then at 2pm the Japanese launched an assault from the north and north east of the Australian position, firing off mortars. The Japanese were repelled, but they came right back later in the afternoon screaming into a bayonet charge. Over the course of the afternoon 3 major attacks were made to the sound of Japanese bugles. This was a classic Japanese strategy to intimidate the enemy, but it actually aided the Australians as it warned them of the incoming attack each time. The attacks were turned back and during the night the Australians were reinforced by another platoon,  70 men of C company led by Corporal Keith Mew. As the night wore on, the Australians sent out some patrols to try and make contact with their forward positions only to find out they had been wiped out in the attacks. Meanwhile under heavy rain, the Japanese were recovering their wounded and trying to get rid of more pesky booby traps in front of the Australian positions. 

 

The next morning came screams and charging Japanese setting off booby traps all morning long. Dexter responded by ordered the men to shoot mortars and rifle grenades at anything that looked like a Japanese position. At 2pm on the 21st, the Japanese began a heavy attack on one of the forward positions held by Sergeant John Hedderman lying between the Jap track and Lababia track. The attack spread to Roach’s and Lt Edward Exton’s front sending a rain of automatic and mortar fire into the two forward platoons. A bayonet charge along the Jap track was halted within just 10 yards of the forward positions and another one to the right flank got within 20 yards before being stopped. The Australians tossed lead in all forms into the banzai charges, but no matter how much mortar, bullets and grenades were tossed, the Japanese were closing in. Sensing a breakthrough, Moten ordered forward more men from the 2/5th battalion allowing Dexter to reinforce his left flank using a small reserve he had at his HQ. They arrived at the flank just in time to repel another banzai charge. By the late afternoon the Australians had 12 dead men and 10 wounded, they were down to just 55 abled bodies, but the brunt of the Japanese attack was done. The arrival of C company allowed Dexter to reinforce his forward positions, now bolstered to 150 men. 

 

The Japanese did not give up however and continued their attack during the late afternoon. Suffering so many casualties, it looked like the Japanese might break through Exton’s position. Exton and Corporal Martine charged forward to rally their men, getting them through the brunt of another assault. By dusk the attacks began to decrease until the gradually stopped. The night saw a ton of rain, making it miserable for the Japanese who were dragging their wounded and dead comrades through booby trapped jungle. On the morning of the 22nd, Araki sent some patrols to probe Dexter’s left flank who were met by Australian sniper fire. An attack was launched against Dexter’s rear, held by Smiths platoon who overwhelmed the Japanese causing them to give up after 5 minutes. Frustrated by the lack of progress, Araki ordered his two mountain guns from the 14th artillery regiment to start shelling Lababia. However the foliage was too much and only two shells actually landed within Dexters perimeter. Thus when the Japanese recommenced their attacks they were met by the full brunt of the defenders. By night, Araki was forced to toss in the towel and he ordered the men to begin a withdrawal. To cover the retreat, Araki ordered his men to fire heavy automatic guns and motors into Dexter’s position on the morning of the 23rd. The Australians responded the same way, but then Dexter unleashed a nasty surprise. He ordered his units to mark the forward lines with smoke. Soon the RAAF send Bristol Beaufighters in who strafed the Japanese up and down the Jap Track. 

It was an incredible defense, the defenders had been outnumbered 10-1. The Japanese had received 42 dead, 131 wounded while killing 11 and wounded 12 Australians. As Moten would go on to say ‘the engagement is noteworthy and is a classic example of how well-dug-in determined troops can resist heavy attacks from a numerically superior enemy”. Dexter had been pretty much left to his own to defend Lababia and for his excellent leadership he was later awarded the Distinguished service order while some of his platoon commanders; Lt edward Exton, Laurence and Roach received Military crosses and Sergeant John Hedderman received a military medal. Dexter was praised by Moten for “taking every trick during the battle” and one of his colleagues, Captain Jo Gullet described him as“he was too exacting to be popular, although he was a thorough soldier, a good trainer of men and a painstaking tactician”. Lababia was secured, and in the next week major operations were about to begin.

Operation Cartwheel was getting its ducks all in order for a major push set on June 30th. The boys down unda fought like lions to protect Lababia ridge. Outnumbered 10-1 they proved, well dug-in positions sometimes made all the difference. 

- 82 - Pacific War - Operation Cartwheel starts rolling, June 6-20, 1943

Last time we spoke about the aftermath of the battle for Attu. The American victory over Attu meant the end of the Aleutian campaign for the Japanese, Tokyo decided to pull everyone out. Over 6000 Japanese needed evacuation from Kiska and it would be very tricky for the Japanese to get past Admiral Kinkaids blockade. Then we finished up the West Hubei offensive, with a part of it being known colloquially as the Rice Bowl Campaign. The Japanese had brutalized the Chinese, but we’re stopped short of invading Chongqing or Sichuan. Thus for the Chinese it was a victory, but at the same time the Japanese had secured exactly what they wanted, stealing vast amounts of property, notably rice. Vessels left Yichang and sailed further west through the riverways acquiring large sums of goods to help the China war cause. Today we are diving back into the south Pacific.

This episode is Operation Cartwheel starts rolling

Welcome to the Pacific War Podcast Week by Week, I am your dutiful host Craig Watson. But, before we start I want to also remind you this podcast is only made possible through the efforts of Kings and Generals over at Youtube. Perhaps you want to learn more about world war two? Kings and Generals have an assortment of episodes on world war two and much more  so go give them a look over on Youtube.

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. 

So honestly for awhile now we have been hitting the North Pacific and China theaters, which certainly was a change of pace, but as you can imagine these events do not simply move along in a vacuum. Yes a lot was going on in the other theaters and this episode is going to be tackling a lot of different events so buckle up buckos. First we are going to talk about Operation Cartwheel.

The ULTRA intelligence that brought Yamamoto’s death was not the only information the Americans received in April. A lifeboat bearing a list of the names of 40,000 active Japanese officers washed ashore after the battle of the Bismarck Sea. Using this Cryptographers were able to match each name to radio signals from Japanese army units, ensuring General MacArthurs intelligence remained as operationally up to date as it could be. At the same time William Bull Hasley showed to on April 15th to Brisbane to meet with MacArthur and the two hit it off. Halsey would later write this about their first encounter. “Five minutes after I reported, I felt as if we were lifelong friends. I have seldom seen a man who makes a quicker, stronger, more favorable impression. He was then sixty-three, but he could have passed as fifty. His hair was jet black; his eyes were clear; his carriage erect….My mental picture poses him against the background of these discussions; he is pacing his office, almost wearing a groove between his large, bare desk and the portrait of George Washington that faced it; his corncob pipe is in his hand (I rarely saw him smoke it): and he is making his points in a diction I have never heard surpassed. “ Both men would hammer out a plan on April 26th, it was a revision to MacArthur’s Elkton plan, this one would be known as Elkton III, but it was soon to be coded as Operation Cartwheel. 

The plan consisted of 13 amphibious landings in just 6 months with MacArthur and Halsey providing maximum support to each others efforts. The first phase of the plan would see MacArthur seizing Woodlark and the Kirwina islands while Hasley invaded New Georgia. Phase 2 would commence 2 months after the start of the offensive where MacArthur would capture Lae, Salamaua and Finschhafen. Phase 3 would be the seizure of the Shortland islands and Bougainville in the south pacific. In December MacArthur would seize Cape Gloucester in Western New Britain and shortly after that they would seize Rabaul. Halsey’s forces would knock out Japanese air bases on Buka, allowing MacArthurs men to clear the northwestern half of New Guinea. By January of 1944, MacArthur and Halsey figured they would be ready for the final assault on Rabaul which was their ultimate objective for victory.

MacArthur resisted sending details of their joint plan to Washington, probably fearing the Europe first obsessed chiefs of staff would veto their ambitious thrust. He told them only that he anticipated that the first move toward Woodlark and Kirwina would start in June. However this was too slow for Admiral King. King wanted his protege Admiral Nimitz to begin a thrust into the central pacific, heading through the Marshalls in November and proposed shifting the Marine 1st and 2nd divisions, the ones that fell under MacArthurs and Halsey’s command to help with the Marshalls offensive, this alongside two bomber groups promised to General Kenney. MacArthur was very pissed off and he sent a distressed message to George Marshall damning the entire central Pacific strategy as a quote “unnecessary and even wasteful diversion from what should be the main pacific strategy”,  that being MacArthur’s own.”. He added in “from a broad strategic viewpoint, I am convinced that the best course of offensive action in the Pacific is a movement from Australia through New Guinea to Mindanao. Air supremacy is essential to success, for the southwestern strategy where large numbers of land-based aircraft are utterly essential and will immediately cut the enemy lines from japan to his conquered territory to the southward. Pulling any additional heavy bombers groups would in my opinion, collapse the offensive effort in the southwest pacific area…in my judgment the offensive against Rabaul should be considered the main effort, and it should not be nullified or weakened ”.

But King was adamant. There would indeed be a thrust through the central pacific led by the navy with its main axis passing through the Marshalls and Marianas towards Japan,which might I remind you listening, bypasses the Philippines. It of course was a strategy completely at odds with MacArthurs. Marshall supported King, as did the other Joint Chiefs. But in the end MacArthurs whining forced King to relent on the transfer of the two marine divisions and the bomber groups, thus MacArthur revealed his timetable for operation Cartwheel. He told them he planned to take Kiriwna and Woodlark in the Trobriand Island around June 30th. The advance on New Georgia would start on the same date, and in September the First Cavalry and 3 Australian divisions would begin operations against the Madang-Salamaua area. Meanwhile MacArthur's 43rd division would invade southern Bougainville on October 15th, while the 1st Marines and 32nd division would invade Cape Gloucester on December 1st. 

For all of these amphibious landings, there were no serious problems when it came to shipping and landing craft….that is for Nimitz designated areas. However at the beginning of 1943, MacArthur had practically no amphibious equipment nor experts in these types of operations. The only units available to him were the Army’s engineering special boat brigade which had very few small craft. The man who would be responsible for the amphibious assaults during much of the coming campaigns was to be Rear Admiral Daniel Barbey. On January 10th, 1943 he took command of the forces that would later be designated the 7th Amphibious force. Barbey from the offset established good relations with MacArthur…because well anyone who worked with MacArthur had to. He had nearly nothing to work with in the beginning, but started with establishing bases at Toobul Bay, near the mouth of the Brisbane river and Point Stephens. MacArthur had requested more small craft and transports as early as mid 1942, but because of the European and central pacific being a priority, little had come his way. Before the equipment came, MacArthur was receiving American and Australian troops, so he got Barbey’s team to improvise. They began training the troops in debarking from larger ships down cargo nets to smaller landing craft. However Barbey had no attack transports (APA), which was the key to this kind of operation. To solve this they rigged nets from cliffs, boy that must have been fun. The first Landing ship tanks LSTs and Landing craft tanks LCTs would not arrive until mid january, and on Easter Sunday 13 Landing craft infantry’s LCI’s were delivered, giving them very little time before the first operations were to begin to train the crews on how to use them. 

Now on the other side Halsey had his own three phase operation. Part 1 saw the invasion of New Georgia, part 2 was the seizure of Buin and Rekata Bay if possible and last 3 was the seizure of Kieta and the neutralization of Buka. Phase 1 was codenamed Operation Toenails. Halsey described the operation to Nimitz as “a infiltration and staging operation”. The operation would see simultaneous landings at Wickham Anchorage to hit its landing craft base; Segi point for its airfield site; Viru Harbor for its small craft base and Rendova Harbor which would serve as a new base to stage troops for a future attack upon Munda. This would all occur on June 30th. The main force assigned to Operation Toenails was General Hester’s 43rd division. Admiral Turner and his Task Force 31 were in charge of the amphibious landings while Admiral Fitch would toss 1182 aircraft to give them aircower and Admiral’s Ainsworth and Merrill’s Task force 36 would provide further naval support.

On the other side, interservice coordination between the Japanese Generals and Admirals remained intermittent and largely ad hoc, when it was not hostile. General Imamura’s 8th area army HQ at Rabaul stood above Hyakutake’s 17th Army, comprising 3 divisions spread over the SOlomons and New Britain, and General Hatazo Adachi’s 8th Army had 3 divisions on New Guinea. Troop reinforcements were arriving in Rabaul bolstering the garrison at one point to 90,000 men. Vice Admiral Jinichi Kusaka remained in command of navy forces at Rabaul and held responsibility for the defense of the central solomons. Admiral Mineichi Koga had succeeded the slain Yamamoto as commander in chief of the combined fleet, based at Truk. Nowhere in the theater was there a blended command, the army and navy had to coordinate their operations through a meticulous process of “nemawashi / digging around the roots” for a consensus. The Japanese moved new air units into the theater, including more of the elite carrier aircrews that had trained and honed their skills prior to the war, but the loss ratios in air combat was ruining them. 

As a result of the devastating loss during the battle of the Bismarck Sea, the Japanese were forced to change plans. USAAF and RAAF aircraft based at Port Moresby and Milne Bay had slaughtered an entire convoy of Japanese transports attempting to land troops in the Lae-Slaamaua area using a new technique called “skip bombing”. Imperial General HQ set up a joint Army/Navy investigation board to study the disaster, seeing the IJA accused the IJN of being too focused on the Solomons rather than on New Guinea. The Army argued New Guinea was vital for the national defenses and proposed that if a retreat became necessary, it would be as a direct result of the navy’s lack of support. If this were to happen they would have to pull back and create a defensive line from northwest New Guinea to Timor. The Navy’s representatives argued that the Huon Peninsula must be held or its loss would swing open the western gate to Rabaul, forcing the combined fleet to withdraw from Truk. Well the fighting eventually resulted in an ultimatum with both sides agreeing the army/navy operations should focus on eastern New Guinea.

It was decided that both the army and navy would literally operate as one unit, because that would go well. The Central solomons were still under the overall responsibility of the 8th fleet, now commanded by Vice Admiral Baron Samejima Tomoshige with some IJA units placed under naval command according to agreements made between General Imamura and Admiral Kusaka. It seems the Japanese could get along once and awhile, as just like Halsey and MacArthur, Imamura and Kusaka developed a deep friendship. Both of their staffs ate lunch together once or twice a week, where southeast area affairs were discussed informally and their respective staffs got to know another personally. Kusaka went on the record to say Imamura was a very great person. Many army units would be sent to reinforce the New Georgia defenses and by late May the bulk of the 229th regiment arrived to Munda, and the 13th regiment went to Vila by late June. Imamura placed both regiments under the command of Major General Sasaki Noboru’s southeast detachment who responded directly to Samejima. Samejima’s first orders were to arrange the responsibilities between General Sasaki’s southeast detachment and Admiral Ota’s 8th combined SNLF, seeing Sasaki in charge of Munda and Ota in charge of the Enogai and Bairoko area’s. If the situation arose, command would be unified under the senior officer on New Georgia, General Sasaki. Ota would also have responsibility for coastal artillery defense, radio communications, and barge operations.

Admiral Koga in his new role as commander of the combined fleet, preemptively sent move of his forces back to the home islands in preparation to reinforce Attu. But as the fate of the Aleutians became sealed by late May, Koga decided to concentrate the combined Fleet at Truk, so it would be primed and ready for a decisive naval battle with the Americans. Without the aid of Koga’s carriers, Kusaka had launched another air counteroffensive after I-Go, this one taking place in June. The aim was yet again to prevent the Americans from invading the central solomons . Kusaka began tossing waves of Bety’s against American shipping east of San Cristobal and night raids over guadalcanal. Simultaneously he also unleashed Operation SO; a major offensive to smash allied air power in the Solomon islands; and operation SE: which targeted airfields and shipping. He sent 105 Zeros to sweep and bomb the enemy airfields with a new type of gasoline bomb. Operation SE began with 25 Val dive bombers attacking US shipping in the Guadalcanal-Tulagi area and Operation SO began on June 7th with 81 Zeros led by Lt Commander Shindo Saburo assaulting the Russels. However the Russel group ran right into 104 allied fighters who shot down 9 Zeros. A follow up attack was made on the 12th with 74 Zeros led by Lt Miyano Zenjiro, this time the Japanese lost 7 fighters but took down 6 American. As usual the Japanese pilots made wild claims, stating the first attack saw 41 American fights shot down and the second attack 24. 

Kusaka launched the main attack of Operation SE on June 16th led by Lt commander Saburo consisting of 24 Vals and 70 Zero escorts who swung south of the Russells, turning at Beaufort Bay. Yet again they were intercepted, this time by 74 allied fighters over BEaufort Bay and the ensuing ari battle rolled over the mountainous spine of guadalcanal. This time the Japanese lost 15 Zeros and 13 Vals while only shooting down 6 allied fighters. The Japanese lost first rate pilots such as Lt Miyano who had scored a total of 16 kills during the war. Again Japanese veteran pilots were being bled dry severely affecting the nation's airpower. Despite their waves being intercepted nearly every time, the Vals were able to press through with their attacks and managed to hit the cargo ships Caleno and LST-340. But such results were hardly worth the cost, so Kusaka began to urgently request reinforcements. The carrier Ryhuo would lend her bombers to replace the lost ones, arriving on the 2nd of July. The losses taught the Japanese pilots some bitter lessons and never again would the fly over guadalcanal during daylight as the American CAP was far to powerful.

Over in New Guinea, General Blamey was laying out his plan for the capture of Lae, codenamed Operation Postern which was approved by MacArthurs headquarters. Before the allies would invade Woodlark and Kiriwana, MacArthur proscribed the seizure of Lae and the Markham and Ramu valley. The Markham operations were to be based on Port Moresby while the north coast operations would be staged from Buna and Milne Bay. The invasion of Woodlark and Kiriwana islands codenamed Operation Chronicle would be entrusted to Lt General Walter Kruegers 6th army. The islands northeast of the Papuan coast would allow the allies to have air bases closer to Japanese targets in the Solomons and around Rabaul, thus Blamey had devised his plan to secure the northeastern part of New Guinea. The first phase of his plan was Lae and the Markham and Ramu Valleys; the 2nd phase was to seize a shore base within 60 miles of Lae, he chose Nassau Bay. Nassau Bay would help with the supply problems in the Wau-Mubo-Bobdubi area, as all the supplies were being flown in from Port Moresby. The mountains were serious obstacles for transport aircraft, not to mention the Japanese fighters that could spring out of nearby Lae. Taking Nassau Bay would greatly shorting supply lines for allied troops fighting in the Salamaua region and also allow a junction to be made with General Saviges forces operating at Mubo

The 162nd American Regiment led by Colonel Archibald MacKechnie would help hit Nassau Bay, they would be known as the MacKechnie force. They would seize the high ground around Goodiew Junction and Mount Tambu and the ridges running down therefrom to the sea, allowing the Australians to link up with the 15th brigade at Bobdubi and the American landing force at Nassau. D-day for the Nassau Landing was set for June 30th and it was all going to act as a feint, hoping to lure Japanese forces from Lae to Salamaua. 

Now the last time we left off in New Guinea, General Savige had launched a limited offensive against the Japanese at Mubo and Bobdubi ridge. General Nakano was certain Salamaua was the main allied target and this prompting him on the 29th to order Major General Chuichi Muroya to lead the 51st division to fortify it. In the process Muroya’s men expelled Warfe’s commandos from the northern ridge. To the east of Mubo, Brigadier Moten was trying to take the Pimple, but his 17th brigade would be performing more patrolling than actual attacks throughout the later half of May. Eventually Savige would relieve the exhausted 2/7th battalion with the 2/6th battalion led by Lt Colonel Frederick Wood who would begin an advance on May the 27th. Meanwhile Nakano had brought more reinforcements to defend Mubo and launched a strong counterattack in early May, nearly breaking through towards the main Australian camp at Lababia ridge. On May 23rd Nakano received two battalions of the 66th regiment and began to work out a plan for assembling supplies and ammunition in the Mubo area to prepare for an offensive. Men would move at night in a single file along the narrow jungle trails carrying the materials by hand, through mud and rain. The main train was a slope on Komiatum ridge known to the Japanese as Regret Hill as the hard working soldiers became more exhausted with each passing day marching along it. The Japanese sought to clear out Lababia ridge as far as Guadagasal, thus securing Mubo.

On June 3rd, allied patrols discovered Nakano had reoccupied Markham point which forced Savige to keep the bulk of the 24th away from the action at Bobdubi and Mubo. From their camp at the bank of the Markham Savige ordered patrols to investigate the Nadzab area. On June 14th, a 3 man patrol came across friendly natives at the village of Gabsonkek who informed them of the Japanese activity in the area. They said "that the Japs come to the village every day between 10:00 and 12:00 hours taking everything in sight—pigs, fowls, fruit, etc., without paying; they take native girls back to Lae if they can catch them. The guides would not proceed farther to Ngasawapum because Japan man come up Big Road, cut us off", and they would not go to Narakapor because they claimed there were too many Japs and two big guns". The patrol went back to camp by the 18th informing command. A second patrol was made, led by Lt Dave Burke who forded the Tabali River to get to Nassau Bay. Their report indicated the area was suitable for landing and road construction. To further prepare for the American landings, the Australians began building a footbridge over the Bitoi River and blazed a track up to Bitoi Ridge. On Lababia Ridge the main defensive position withdrew to a junction on the Jap Tracks where it would be easier to counter enemy encirclement attempts.

Reports came in from forward platoons that there was considerable enemy activity along the Komiatum-Mubo track. This was Nakano’s 66th regiment carrying the food and ammunition in preparation for the upcoming offensive. In response to this, Savige ordered Brigadier Frank Hosking of the 15th brigade to assume command of the Bobdubi ridge area and to begin harassing the Japanese supply route. Meanwhile the 58th/59th battalion relieved the 2/3rd independent company at Hote and a party of Warfe’s commando’s were sent to attack the Komiatum-Mubo track. However disaster struck as the Australians ran into their own booby-traps on June 16th suffering a number of casualties. By June 20th, the commando’s established ambush positions along a ridge near the junction of Stephens Track and the Komiatum Track. They successfully ambushed some Japanese later that day, killing a few men and capturing valuable documents about the arrival of Nakano’s 66th regiment. However by this point Nakano’s units were already assembling in front of Lababia ridge and the offensive was about to begin. Now we gotta finish up the episode talking about some developments in India.

After the disastrous first Arakan Campaign, Marshal Wavell was to receive a promotion, and by promotion I mean he was kicked upstairs as they say, succeeded Lord Linlithgow as the new Viceroy of India. But until then he began looking into training his forces in jungle warfare as the bitter lessons learned at Arakan proved the men were very unprepared. Wavell also wanted to investigate what the hell had happened during the disaster, so he sent Major General Roland Richardson in late May to head a infantry committee at New Delhi for the task. The committee’s report about the Arakan campaign found the troops fighting spirit was fundamentally sound, but the major problems that affected their combat performance were more about the over expansion of the army in India. The army mobilization had been rushed, they barely met basic training and the supplying of their sheer numbers was a catastrophe. There were also issues regarding their low status, inferior pay for the infantry, which further deprived them of skilled and well educated recruits.  Yet above all else the Infantry committee found their lack of jungle training to be the most egregious issue. As observed “This is the most urgent problem facing us, and one which requires prompt and energetic action if results are to be produced in time for the winter campaigning season.” The lack of jungle training severely undermined their ability to fight efficiently and ultimately led to the breakdown of infantry battalions in the Arakan. And of course there was the ever present unseen enemy, that of malaria, alongside an assortment of other ailments that were wreaking havoc on the men.

But many of these problems could not be tackled until June 20th, when General Claude Auchinleck was officially appointed as the new Commander in Chief in India. For General Slim this was excellent news and certainly worked in his favor alongside the sacking of Irwin. The “Auk” as he was called, had always been a Slim supporter and was the one who recommended him to Wavell for advancement when Wavell was Commander in Chief of the middle east back in 1941. The Auk had wanted to retain Slim in the middle east and fought hard to dissuade Wavell from taking him over to Burma. Churchill never held Wavell ever in high regard and was tired of his quasi-academic effusions and preferred a “fighting general” in Burma. Alongside the Auk, Irwin was replaced with General George Giffard, and Slim had this to say of the replacement. 

“The new Army Commander had a great effect on me. A tall, goodlooking man in the late fifties, who had obviously kept himself physically and mentally in first-class condition, there was nothing dramatic about him in either appearance or speech. He abhorred the theatrical, and was one of the very few generals, indeed men in any position, I have known who really disliked publicity . . . But there was much more to General Giffard than good taste, good manners and unselfishness. He understood the fundamentals of war – that soldiers must be trained before they can fight, fed before they can march, and relieved before they are worn out. He understood that front-line commanders should be spared responsibilities in the rear, and that soundness of organization and administration is worth more than specious short-cuts to victory”

Auckinleck went to work from the offset of his new command by improving the welfare, health and feeding of the Indian army to foster improved morale. General Giffard as the new commander of the Eastern Army had Major General Temple Gurdon to oversee some reforms for training and the development of new doctrines. A lot of effort was made to conduct intensive collective training under jungle conditions. The men would train near Nasik, Ranchi, Dehradun and in the Jhansi-Nowgong-lalitpur region. Commanders low to high were given a chance at handling units to improve standards of staff work, practice combined army tactics and build team spirit. Auchinleck also initiated a policy of active patrolling at Assam and Arakan to gather intelligence and maintain touch with the Japanese as to destroy the feeling that they were super soldiers.

A lot of chess pieces were moved around the board this week. Bitter lessons had been learnt in multiple theaters of the war and now it came time to reorganize and try new things to ultimately bring the war against Japan to a closer end. 

- 80 - Pacific War - The rice bowl campaign, May 30 - June 6, 1943

 

/Last time we spoke about the fall of Attu. The Americans had to fight both the Japanese and a very cruel mother nature to claim the frigid island of Attu. The Americans gradually seized every hill, ridge and razer edge crest as the pushed the Japanese into Chichagof Harbor. Once the Japanese had their backs to the sea and nowhere left to withdraw, Colonel Yamasaki decided they would go out in ablaze of glory. Nearly 1000 screaming Japanese performed a suicidal Banzai charge towards the American artillery positions, hoping to unleash the enemies guns upon them. Yamasaki received an M1 Garand Bullet as the rest of his men killed themselves en masse clutching grenades to their chests. It was a horrifying conclusion fit to make the last Samurai Saigo Takamori proud. Now the Americans turned their gaze back east upon the isolated Kiska. 

This episode is the Rice Bowl Campaign

Welcome to the Pacific War Podcast Week by Week, I am your dutiful host Craig Watson. But, before we start I want to also remind you this podcast is only made possible through the efforts of Kings and Generals over at Youtube. Perhaps you want to learn more about world war two? Kings and Generals have an assortment of episodes on world war two and much more  so go give them a look over on Youtube.

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. 

We left off with the fall of Attu to the Americans. Colonel Yamasaki’s doomed garrison made one last banzai charge into oblivion, leaving piles of their dead over the island. The Americans had suffered substantial casualties, making the battle of Attu the costliest ground battle as of now fought in the Pacific. In the words of General Bucker “[The Japanese proved to be a] tough fighter, with great physical endurance and fortitude. He was not afraid to die.”  A number of lessons were learnt from the battle, including new landing techniques, and the necessity for rubberized, thoroughly waterproofed boots. The men on Attu had been given expensive, thick and insulated leather hunting boots, but these became absolutely useless once soaked in water. After Attu, improved winter kits emerged, and cases of hypothermia, frostbite or trench foot would become very rare among American soldiers even during bitterly cold campaigns in Italy and France. The Americans also learnt how masterful the Japanese were at creating concealed defensive works and at infiltration tactics.

The American forces got to see first hand how weather and terrain could pose the greatest threat to success. The Hourglass Division, owing to its initial desert training, was not prepared for Attu conditions, which demanded cold weather and mountain warfare expertise, clothing and equipment. In addition to being inadequately clothed, they failed to take care of themselves on the battlefield. The 7th Provisional Scout Battalion was only able to muster 40 men to walk after five days of action. In contrast, the 30-man detachment of Alaska Scouts, recruited because of their outdoors skills and experienced in Alaska conditions, lost one man killed in action, two wounded and one man with a slight case of trench foot. These type of lessons would prove very useful in future operations, to point out two, the future Italian and France campaigns which held some cold territories. 

As the battle of Attu was coming to a close, Tokyo issued a directive on May 21st for the evacuation of Kiska’s 6000 man garrison led by Rear-Admiral Akiyama Monzo. The evacuation was going to be done using 13 I-class submarines from the1st submarine squadron of Rear-Admiral Kouda Takeo. But by early June Takeo would already realize the danger of using his force for such a task as one of his submarines would be sunk at Attu. There was a call to use surface ships if the weather permitted it and continuous calls to rush over to evacuate the Attu garrison, but the American naval blockade put an end to that idea and worse now it seemed the Northern Kuriles were in danger. Now Tokyo sought the deployment of fighters and anti-aircraft units to provide air defense and shore batteries to thwart an amphibious invasion of the Kuriles.

The Japanese had a daunting task laid before to them. In contrast to the relatively weak American naval forces deployed at the battle of the Komondorski islands, Admiral Kinkaids blockade and bombardment forces included the a trio of older battleships; the Mississippi, Idaho and New Mexico, a quintet of cruisers; Louisville, Portland, San Francisco, Santa Fe and Wichita and 9 destroyers. This powerful fleet showed up on July 19th under the joint command of Rear Admirals Robert C Giffen and Robert M Griffen, very close names there lol. Other destroyers and submarine chasers were operating in separate smaller commands within the region. Admiral Kawase Shiro took over IJN operations in the Aleutians and North Pacific following Hosogaya’s removal from command and thus found himself stuck with rescuing Kiska’s garrison from the teeth of a very powerful American blockade. Lacking the fleet strength to punch a hole in the blockade, thus Kawase had turned to submarines.

The 12 submarines under Takeo were Type C’s, heavily armed with torpedoes, deck guns and measured 358 feet long. Kawase’s first plan was to try and slip submarines through the blockade, but despite being large, the submarines could barely carry 150 men each, thus it would require 40 successful journeys to remove the entire garrison. With most American warships now equipped with sonar, this represented a hell of a risk, forcing Kawase to look towards other options. While the submarines would make runs as soon as possible, Kawase had to plan a surface evacuation.

The Japanese submarine evacuation of Kiska began on May 27th with the first submarine, the I-7 arriving at Kiska with food, ammunition and a radio beacon. She could only carry 60 passengers, which was reserved for the sick and wounded alongside 28 boxes of ashes for those who had died on the island and 4 tons of spent shell cartridges. A few more submarines managed to make the trek and evacuated a few hundred men from Kiska, but then the Japanese luck changed for the worse. The I-24 captained by Hanabusa Hiroshi, entered Kiska harbor in early June taking aboard 150 soldiers. On the night of the 10th, she was trying to slip away but as she was passing 40 miles north of Shemya Island, American sonar aboard the USS Larchmont, A pc-461 Class Submarine chaser pinged. Lt Wallace Cornell ordered is crew to depth charge the enemy submarine tossing 5 of them into the water. The Americans blasted the I-24 to the surface. Then Cornell ordered the Larchmont to put the pedal to the metal flooring the 450 ton sub chaser to ram the 2554 ton I-24. Larchmont rode up and over the submarine splashing into the sea on the far side. Upon seeing they failed to ram her, Cornell’s men began pounding the vulnerable I-24 with shells, before turning around to try ramming her again. This time the Larchmouth smashing into the I-24’s conning tower, fatally damaging the submarine. She sank stern-first into the black, frigid sea killing her 104 man crew and the 150 soldiers she was bearing.

Three days later, the destroyer USS Frazier sank the I-31 taking down her entire crew and the 150 soldiers she was evacuating. Out of 800 total men the submarine forces got off the island, 300 of them died to American attacks. As the summer would continue, combat and operational losses would see the destruction of 8 out of the original 13 submarines, leaving Takeo with 5. Kawase recognized the futility of the submarine operation and was forced to turn to his surface plan which would unfold in late july.

While all of this was going on, the Americans invaded the islands of Shemya and Agattu. Brigadier General John Copeland led elements of General Buckner’s 4th regiment and Colonel Talley’s 18th Engineers to land on Shemya during a tough storm. The Americans quickly surveyed the island to see if they could construct an airfield to accommodate a brand new experimental aircraft, the most iconic one of the Pacific War, the B-29 Superfortress heavy bomber. She had been in the works since 1938 and her objective would soon be long range bombing missions against the Japanese home islands. With their usual blinding speed, the American Engineers made the Attu air station operational by June 8th, then Shemya’s two weeks later. Alongside this the 11th air force would be reinforced with squadrons of the new PV-1 Ventura bomber, equipped with the latest airborne radar, which was capable of giving a clear picture of topographical contours that would be extremely useful while flying through the arctic weather and at night. Admiral Kinkaid would likewise shuffle his ships around to improve the blockade and General Butler’s airforce would spend most of June smashing Kiska with bombs. They would fly a total of 407 bombing sorties, though the Japanese arsenal of 70 anti-air batteries would give them a hell of a time doing so.

Completely uncontested the Americans would make unopposed landings on Semisopochmoi and the Rat Islands, covered only by PT boats. With these newly acquired airfields such as Attu and Shemya and the new aircraft on hand, the Americans were in sufficient range to bomb Paramushiro, Japan’s Gibraltar-like base guarded its northern approach. The first raid against Paramushiro would occur on July 10, with 6 B-24’s launching from Attu, but suddenly getting redirected to hit 4 Japanese wooden transports trying to breakthrough the naval blockade for Kiska. Although the American pilots successfully sunk 2 of them, they would not have enough fuel to continue on to hit Paramushiro. Another attempt would be made on Jul 18th seeing 6 B-24’s inflicting minimal damage upon Paramushiro, but it showed the Japanese their home soil was no longer safe from American bombers.

Tokyo was forced to reinforce the Kuriles and Hokkaido taking up valuable resources in men, guns, ships, aircraft and such from other places they were needed like the Solomons. Because of their large success, Buckner and Kinkaid saw significant budget increases and now the Joint Chiefs were seriously thinking about invading the Japanese home islands from the Aleutians. They went as far as to create plans with 1945 designated as the year they would invade Japan. Now we are shifting away from the north pacific to dive back into the situation of the second sino-japanese war.

The last time we were in China, the battle of West Hubei was raging on, with the 11th army of General Yokoyama invading south of the Yangtze River. Now Yokoyama would press on against the southwest portion of Yichang where the Chinese 11th division was defending Shipai Fortress; the 18th division was at Changyang and the 24th and 36th independent engineer battalions were at Yuyangkuan. The Chinese 11th division was led by General Hu Lien who held a considerably well defended fortress at Shipai, but also its approach which was the dangerous Xiling gorge. All combined, these defended the approach to Chongqing and Sichuan. Because of its vital importance, Commander Chen Cheng ordered Hu Lien to defend Shipai fortress to the death. By May 18th, the second phase of the IJA operation came to its conclusion, thus Yokoyama decided to concentrate his 13th division near Quanshuiwan, and his 3rd division backed by the Nozoe detachment near Shuangjingsi. This was in preparation for the third phase of the operation, a final drive against the Chinese defenses between Yichang and Yidu.

The IJA 13th Division began to move north while the 3rd and Nozoe detachment advanced south of Yichang to cross the Qingjiang river. The Japanese found many Chinese defensive positions along the way, but by this point the Chinese had been so brutally battered over the past month, they were still dazed and confused, thus easily brushed aside. The 18th army would manage to hinder the Japanese advance, forcing Yokoyama to redirect 3 battalions of the 39th division to join the offensive. By May 22nd, the 39th forded the Yangtze and joined up with the 3rd and Nozoe detachment to assault Changyang. As the Japanese forces approached Shipai Fortress from three directions, Commander Chen Cheng and General Sun Lianzhong tossed the 94th and 32nd armies to try and stop the Japanese advance at Yuyangkuan. Chen Cheng’s plan was to box in Yokoyama’s forward units at Yuyuangkuan, but instead the Japanese began dispersing and clashing with the Chinese 18th army at Changyang alongside Yuyangkuan by May 23rd. The defenders still jarred from the offensives were routing left right and center.

Fortunately the Chinese would manage to pull themselves together to reorganize a new defensive position to the right of the Shipai Fortress. Their last line of defense was to be at Muchiaochi, in front of Congqing and Sichuan, held by the 34th division. The Japanese were relentless as they continued their advance and by the end of May 26th they reached the defensive line. At this point Yokoyama had achieved his objectives as the vessels at Yichang could now advance towards Yueyang without facing resistance. He quickly ordered 53 steamers to navigate the river on the 27th, but then they were met with an expected enemy, the Major General Chennault's Flying Tigers.

During May of 1943, as we have seen, the Japanese launched a ground offensive targeting areas like DongDongting Lake and the Yangtze River region. The objectives were clear to the allies, the Japanese were seizing the colloquially called “rice bowl” region, right during harvest season. As the ground fighting intensified it became clear that the CHinese land forces desperately needed aerial support.

To counter the Japanese, the recently created 14th airforce as of march 10th 1943 led by Chennault and the Chinese 4th air group tossed P-40E’s and P-43’s to try and support the Chinese ground forces. On MAy 14th, Japanese reconnaissance covered Kweilin and Lingling, estimating the US order of battle was 24 P-40s, 8 B-24’s, 3 B-25’s, 1 P-38 and 1 P-43. It was also noted that the Chinese had advanced to Liangshan where their 4th air group was located. 

The 4th air group went into action by May 19th with 8 P-40E’s, 4 P-43’s, alongside some A-29 Hudson bombers. The Chinese bombed the Japanese ground forces meeting some intense anti-aircraft gunfire back. Deputy group commander Xu Baoyun, flying a P-40E was shot down by Japanese anti-aircraft gunfire in the process. The next morning the Japanese bombed Liangshan by surprise giving the 4th air group no chance to retaliate. From May 19th-June 6th, the Chinese Air Forces would fly 336 fighter and 88 bomber sorties over the battle zone claiming to have shot down 31 Japanese aircraft. The 4th air group missing their chance to confront the Japanese on May 29th, when they fly from Liangshan to cover Chongqing due to a false alarm. While they were absent, 10 Japanese fighters strafed the field followed an hour later by 9 Japanese bombers with fighter escorts. On May 31st, 9 P-43’s escorted 5 A-29s to attack the ferry crossing between Yichang and Yidu, but in doing so they would miss the most intense action of the campaign.

On the same day Lt Colonel John Alison, an American ace alongside 2 USAAF wingmen led 7 P-40s from the 4th air group to escort 9 B-24 bombers over to Yichang. It was Alison’s last mission in China and the ace hoped to add to his record of kills. The allied airforce bombed and strafed Japanese ground forces but also got into dogfights with Japanese air forces. Alison’s aircraft was badly shot up by Captain Ohtsubo Yasuto the leader of the 1st Chutai squadron of the 33rd. Lt Tsang Hsu-Lan nicknamed “Bulldog” took his No.2304 P-40 to swing behind Ohtsubo as he was firing upon Alison and managed to shot his aircraft down, saving Alison’s life. Tsang was awarded a American Silver Star and the highest medals China could offer.

On June 6th the 14 K-43’s and 8 light bombers attacked Liangshan. 13 Chinese P-40’s led by COlonel Li Hsiang-Yang were returning from a mission to Liangshan and were landing as the Japanese approached. Captain Chow Chin-kai, commander of the 23rd squadron and a veteran of many years of combat, directed the ground crews to take defensive measures and then apparently climbed into a P-66 Vanguard. Without time to adjust his parachute, check his fuel nor even buckle his seatbelt he gunned the engine. While the Japanese strafed the field, Chow went directly for the bombers, claiming 3 destroyed. Chow received the Blue Sky White Sun award personally from Chiang Kai-shek for this action. Yet despite his heroism, 12 P-40’s and a fleet trainer were destroyed on the grounds of Liangshan.

What became known as the Rice Bowl Campaign took a heavy toll on the CAF. In addition to their loses in combat and on the ground suffered most by P-40’s, many other aircraft suffered from operational damage. After the campaign the operational CAF aircrafts would number 6 out of 7 A -29s, 5 out of 10 SB-3s, 3 out of 5 P-40E’s, 6 out of 9 P-43s and 39 out of 46 P-66’s. The 14th airforce played a small role overall in the Rice Bowl campaign and thus their losses were quite minimal.

Meanwhile at the Shipai Fortress, Hu Lien faced direct attacks from the IJA 68th regiment on May 28th. Told to fight to the death, the defenders managed to repel each enemy assault inflicting significant casualties upon the invaders. Hu Lien would personally led the troops at all times in their efforts to dig in and build fortifications. To the right flank the 3rd and 39th divisions charged against new positions manned by exhausted soldiers of the 18th army, who resisted as much as they could. However they were simply no match for the full might of two Japanese divisions and soon two Chinese companies were annihilated as the rest pulled back. General Luo Guangwen of the 18th Chinese division boldly decided to counterattack, launching a rain of grenade and mortar fire over the 3rd and 39ht divisions halting their advance. Although aided by artillery and aerial bombardment, the Japanese were still pressing hard against the defenders.

The Chinese 94th and 32nd armies then arrived to the scene, and the 94th army went to work successfully blocking the advance of the 13th division near Dayanxiang. This forced the Japanese to cross the dangerous Tianzhu Mountain which would claim much of their equipment. Further down the road, the 13th division was also ambushed by concealed forces of the 32nd army, managing to inflict hundreds of casualties upon them. Because of the increased losses, Yokoyama ordered the Noji detachment at Yichang to cross the Yangtze to assault Shipai Fortress frontally in a last ditch effort to break Hu Lien’s lines. On the 29th, the Noji detachment launched its attack, breaking through Hu Lien’s line at Qiuqianping, inflicting sever casualties upon the 11th division which was forced to retreat towards the bay.

By the end of the 29th, the 18th Army’s other units were also withdrawing, leaving Hu Lien alone to face the brunt of the enemies advance. But by the point the Japanese had suffered tremendous losses and the steamers at Yichang had already arrived to Shishou, thus Yokoyama feared he was overstretched and that his forces might get trapped by Chinese units moving to Changyang. Thus not wanting to see things fall apart, Yokoyama ordered an end to the operation on the 29th and preparing his forces for a withdrawal. But the next day the 13th division decided to press an attack upon Muchiaochi, not knowing the 32nd Army had set up another ambush for them there. The Chinese unleashed artillery on the Japanese inflicting more casualties on the already battered division. Meanwhile the isolated 11th division was repealed the combined attacks of the 3rd and 39th divisions, repelling 10 consecutive attacks throughout the day, leaving the bay area full of dead Japanese. on the 31th the Japanese began their withdrawal as more and more Chinese reinforcements were arriving for a massive counterattack. While the 3rd and 39th divisions managed to avoid battles as they crossed the Yangtze at Yichang, the battered 13th division was heading towards Yidu and was trapped by the 32nd army at Changyang by June 3rd. The 13th division would manage to break free and flee towards Gongan, but the division which was earmarked to depart for the Pacific, lost so many men they would be forced to remain in China. Yokoyama was forced to send the 17th independent mixed brigade who had already managed to withdraw to Shishou to rescue the 13th division. They arrived to Gongan on June 5th, and fight a long series of battles to help the remnants of the 13th division to limp back to Shishou by June 8th.

With the Japanese operation concluded, Commander Chen Cheng and General Sun Lianzhong would successfully recapture most of the lost territory and begin rebuilding defensive lines as they did. The Japanese claimed to have suffered 3500 casualties with 771 dead and 2746 wounded, though it should be noted other sources claim their losses were considerably higher, as the 13th division was practically destroyed, the 17th mixed brigade, 3rd and 39th divisions were also severely damaged indicating losses possibly in the tens of thousands. The losses were so grave, the Japanese would not be able to start another offensive in China until the end of the year. Thus the gateway to Chongqing and Sichuan were held, paraded as a grand victory by the Chinese. As I indicated in a previous episode however,  Historians such as Barbara W. Tuchman suggest "the Japanese withdrew without pursuit from what appeared to have been a training and foraging offensive to collect rice and river shipping." In other words, the Rice Bowl campaign as it became known, basically saw the Japanese stealing the bowl of rice for 1943. 

Now we are not done just yet, there is some action going on in the Solomons. The Japanese had just conducted Operation I-Go and despite their pilots extremely overexaggerated claims, it truly was a lackluster offensive. Alongside this the legendary Admiral, Isoroku Yamamoto had been assassinated on April 18th, shattering Japanese morale. Nonetheless the show had to go on as they say and now Admiral Kusaka would need to reorganize, repair and reinforce his air forces in preparation for the next expected American offensive in the Solomons. Kusaka was reinforced with the 12th Air Fleet; consisting of the 24th and 27th Air Flotillas. The 11th Air Fleet meanwhile, would be reinforced with the 25th Air Flotilla  holding 60 Zeros, 10 J1N1s and 50 G4Ms. Kusaka’s 26th Air Flotilla, who should have been relieved, would be forced to fight on for the duration of the campaign against Rabaul; but the 21st Air Flotilla would be sent to Saipan for rehabilitation.

Now since the evacuation of Guadalcanal, the Japanese had created a new defensive line with Rekata bay being the hub for the Santa Isabel defense line and Munda the hub for New Georgia with its forward post at Wickham anchorage. This meant forward bases needed to be reinforced, so Santa Isabel received the 7th Combined Special Naval Landing Force of Rear-Admiral Katsuno Minoru, consisting of the Kure 7th SNLF and the 3rd Battalion, 23rd Regiment. New Georgia received the 2nd battalion, 229th regiment of Captain Iwabuchi Sanji, the 41st antiaircraft battalion, the 4th, 10th and 22nd construction units who went to Munda, the 1st battalion, 229th regiment and 1st machine-gun company who would go to Wickham anchorage. Kusaka envisioned the main defense force to be Rear Admiral Ota Minoru’s 8th combined SNLF. This consisted of the Kure 6th and Yokosuka 7th who had recently been converted into heavy artillery units originally set to for hitting the Americans on Guadalcanal. Other support, rifle companies and heavy weapons compies made up the rest of the SNLF force. By late January Ota’s force began its movement to New Georgia, arrived to Munda by the end of the month, though a large air strike rocked them on January 29th sinking 75 barge loads of valuable cargo. The Japanese sent various forces to occupy Vila and Rekata Bay in January where bases would be developed. 

On February 27, Choiseul coast watchers spotted Kirikawa Maru carrying two 14cm guns, four 8cm dual-purpose guns, 600 tons of ammunition and supplies, and SNLF personnel as the ship and its two escorts cleared the Shortlands. A PBY and the coast watchers reported their course, and a COMAIRSOLS strike force of fourteen SBDs, with an escort of twenty-four fighters, caught them three miles off the northeast tip of Vella Lavella. The escort took on the thirteen Zeros and two F1Ms flying cover, and in the fight that followed each side lost two aircraft. The SBDs went about their business with deadly effect; a surviving Japanese medical officer later wrote that the bombs were exploding in the ship like a fireworks exhibition at Ryōgoku Bridge in Tokyo. This would force the Japanese to yet again rely on the good ol Tokyo express much to their dismay. Alongside that the battle of Blackett strait on March 6th forced the Japanese to avoid the Kula gulf and instead op for the Fergusson passage. Through march to May the Japanese would suffer only one loss, the sea truck Gisho Maru, thus the new route seemed to be successful. However with all of the shuffling by both sides it seemed evident, a new bloody campaign was about to be unleashed in the Solomons.

The Japanese struck hard into the heart of China’s Rice Bowl Region. Both the Chinese and Japanese lost significant amounts of men to the bloody campaign, Chongqing and Sichuan were safe, but in the end the Japanese had secured their objectives.

 

- 79 - Pacific War - Fall of Attu, May 23-30, 1943

Last time we spoke about the battle of Attu. The American forces were gradually taking the high grounds from the Japanese. The stalemate at Jarmin’s pass had caused severe casualties upon the Americans, but they managed to get the Japanese to withdraw from the Pass by May 17th. Jarmin’s Pass would receive its name after Captain John Jarmin and his platoon died fighting atop it on May 14th. We also spoke about the silent service and how the Mark 14 torpedo was gradually fixed so the submariners would be better equipped to strangle Japan of her lifeblood, her merchant fleet. Lastly we spoke about the horrifying Changjiao Massacre that occurred during the West Hubei Offensive and the plight of the common Chinese people during the brutal second sino-japanese war. But today we are going to finish up the story of the battle for Attu. 

This episode is the Fall of Attu

So we left off in the Frigid Northern island of Attu on May 16th, with General Brown being relieved of command of the 7th division by the Aleutian veteran Brigadier General Eugene Landrum. Given the evidence on hand today, it seems Brown had really irritated Admiral Kinkaid and his other military superiors, coupled with miscommunication or better said lack of. The misunderstandings that arose saw Brown kicked out, but before he departed he had the chance to speak to Landrum. Landrum was shocked when he saw the situation for what it really was and sympathized with Brown. He ordered all of Brown's plans to continue as they were. 

Now back on Attu, the Northern Force of Colonel Culin was making a major breakthrough by cutting off Lt’s Goto and Honna and their forces in Jarmin Pass. They were forced to abandon their positions during the night of the 16th, slipping away and successfully eluding all the American forces as they joined Colonel Yamasaki’s main body at Chichagof. The following morning the Americans failed to realize off the bat that they were no longer facing any Japanese atop Jarmin Pass, as a result of the thick fog. Eventually the lack of bullets coming down upon them brought the realization that the brutal massacre valley struggled which had to this point claimed 1100 American casualties had ended.

Over in the south Colonel Wayne Zimmerman walked atop the crest of Jarmin pass where he stumbled upon the corpse of Captain John Jarmin and the bodies of his comrades surrounded by mangled bodies of dead Japanese. The pass which was called Massacre-Holtz pass was renamed after Jarmin who died on the 14th. The pass would receive a renaming There was an eerie silence over the pass that day. On May 18th the various Americans forces finally established contact through Jarmin Pass and now looked towards Chichagof where the Japanese were looking to make a stand. Despite successfully dislodging them, the Japanese had managed to withdraw in order, establishing yet again well-prepared defenses on the jagged heights of Chichagof Valley. 

Landrum decided to give the men another day to recuperate and plan out their attack and as he noted later “I know this country and my heart bled for the boys. I had to send them up there. I know how cold and bitter it was on the mountains. But I knew death was bitterer.”.On May 18th the American officers got together to formulate a plan to assault the Japanese. Colonel Culin would lead one Pincer and Colonel Zimmerman the other, this was part of Major General Browns original plan. Zimmerman's 2nd battalions, of the 17th and 32nd infantry with the 3rd battalion of the 17th infantry in reserve would seize Clevesy pass. Once that was taken, the Southern force would then advance down Jim Fish Valley to seize Sarana Nose on the right side and Buffalo Ridge on the left thus securing the approaches to Chichagof harbor. Culin’s Northern Force and the 1st battalion of the 4th regiment would capture the northern slopes of Prendergast ridge in preparation for the final assault against Chichagof. Culin and Zimmerman shuffled their more exhausted units into reserve, allowing fresher troops to take the lead. Meanwhile in his Kingfisher Colonel Eareckson flew reconnaissance missions almost constantly, scouting, coordinating and occasionally dropping messages to isolated units he could find. Eareckson relayed targets back to the bomber units so they could try to hit the enemy who had been alluding them heavily for days because of the deep fog. Colonel Talley’s Engineers were also at work, building a road towards Engineer hill to help move the artillery piece further inland. Admiral Rockwell also sent a force of PT boats to carry further supplies ashore, hoping to reduce the enormous traffic jam of supplies along the beaches.

During the night of May 18th, Zimmerman and Culin sent scouts to probe the enemy defenses at Clevesy Pass. On the morning of the 19th, the offensive began, with Zimmerman sending his 2nd battalion 17th regiment to hit Clevesy pass supported by an artillery barrage and Culin sent his two battalions against the Chichagof heights. By noon, the 2nd battalion, 32nd regiment joined the southern attack. Culins advance finds out the Japanese position at the Chichagof heights are quite formidable. Lt Honna has taken a position at a place called Point Able, a mountain blocking the Southern forces advance. Lt Honna who spoke perfect english notably would be spending the fighting at Point Able lobbing elaborate insults and taunts at the American invaders. For Zimmerman’s men, they had the support of a ton of artillery and some aerial bombardments to soften up Clevesy Pass allowing the men to capture a toehold on the high grounds. However Zimmerman’s men quickly found themselves embroiled in a major battle, as Dr. Paul Tatsuguchi tells us via his diary “The hard fighting of our 303rd Battalion in Massacre Bay is fierce and it is to our advantage. Have captured enemy weapons and used that to fight enemy closing under fog.” Lt Honna and his 303rd independent battalion fought like madmen to hold Point Able. The next day, Zimmerman sent some companies to perform an early morning attack to seize Cold Mountain while the Japanese reigned machinegun fire upon them. By noon the American attacks had reduced the Japanese to a force of 50 men upon Nees Point who were tossing back continuous american attacks. Meanwhile Culins men were fighting their way inch by inch over bloodstained hills. By the end of the 20th, they gained a few hundreds yards. Also on the 20th, the 1st battalion, 4th regiment entered the fray, hitting Clevesy pass and beginning their ascension to Prendergast ridge. General Buckner’s men were able to reach the top of the ridges the following night before turning their advance towards Sarana-Holtz Pass.

The USS Nassau launched its final mission of the day, sending some Wildcats to bomb and strafe the Japanese positions in the Chichagof Harbor in the afternoon. Again we hear from Dr. Tatsuguchi’s diary “Was strafed when noon, amputating a patient’s arm. It is the first time since moving over to Chichagof Harbor that I went in an air raid shelter… Nervousness of our CO is severe and he has said his last word to his officers and NCOs-that he will die tomorrow – gave all his articles away. Hasty chap this fellow. The officers on the front are doing a fine job. Everyone who heard this became desperate and things became disorderly.” After hitting the Japanese the USS Nassau left for Adak having lost 5 pilots and 8 aircraft to the bitter frigid weather. The next day, General Buckner came over to Attu to support his 4th regiment and had Colonel Eareckson fly him up Massacre Valley to look around Point Able. Buckner apparently even manned the aircrafts machine gun strafing the Japanese trenches. That day Eareckson’s bombers managed to destroy every building in Chichagof village. Eareckson himself would later that day walk over to the frontlines, borrow a rifle from an infantry man and proceeded to shoot at Point Able. For this he was rewarded with an enemy bullet that wounded him. Buckner would get him a Purple Heart to pin to his chest and a firm kick in his ass upon saying “for being where you had no business being”. I think in Eareckson's defense, a General manning a machine gun on an aircraft was just as hilariously improper. 

Zimmermans men continued to push up the mountains against the Japanese, and during the nightfall Company E of the 32nd regiment made a daring charge up the slopes of Point Able ferociously wiping out Honna company down to the last man. Honna would die from a gunshot wound having fought to the bitter end. To the north, Culins man successfully captured Hill 4, leading towards Prendergast ridge, when General Landrum suddenly ordered them to instead support the Southern Forces advance upon Fish Hook ridge. Fish Hook Ridge overlooked Chichagof harbor still held by Colonel Yamasaki who was suffering daily artillery and aerial bombardments. Yamasaki’s men were ordered to hold the beach at all cost. To the left was Jim Fish Valley and Sarana Nose to the right. The defenses on both sides of the entrance to the harbor rendered a direct approach upon Chichagof harbor quite difficult.

 

Sailed from the west, Admiral Kawase was performing reconnaissance around the Komadorski islands and reported back that the size of the American fleet at Attu was enormous. It seems this report finally sunk in with Tokyo HQ, because they made their decision to evacuate the aleutian garrisons via submarine, thus ending anymore reinforcing. The following day, 19 G4M bombers launched from Paramushiro, and through the fog found a patch of clear sky over Holtz Bay where they dropped packages over Chichagof Harbor before they attacked the American vessels. They lost two Betty’s for their efforts inflicting basically no damage upon the American warships.

On the morning of May 22nd, Zimmermans forces ran into the remnants of the 303rd battalions, the 4th company and a few survivors of the 2nd company on Sarana Nose. Zimmerman ordered his reserve 3rd battalion, 17th regiment to hit the peak after the big guns got to smash it for 30 minutes. The big guns referred to 32 heavy machineguns, 14 37 mm anti-tank guns, 23 81mm mortars, a section of 75mm pack howitzers and 4 batteries of 105mm howitzers, a lot of shock and aye. THe bombardment devastated the entrenched Japanese allowing the men to take Sarana Nose with relative ease, annihilating the handful of Japanese. Meanwhile on the left flank, the 4th regiment advanced upon Prendergast Ridge supported by artillery. To the north, Culin attacks stalled due to heavy resistance, so Landrum ordered him to hold his position. Despite Landrums recent broken leg he assumed personally command of the southern force. 

May 22nd’s aerial photos showed that leading a direct assault up the valley floor would bring the southern force into an inferno of lead from the surrounding ridges that overlooked the valley. So instead they would secure Fish Hook Ridge first. Fish Hook ridge was a rugged semicircular snow covered, knife edge ridge which bent like a fish hook around 2 miles towards Chichagof Harbor. The Japanese had made a defensive line of snow trenches, rifle pits and machine gun nests connected by snow tunnels along the slopes of Washburn and Newman Peaks. These extended further south to the slopes of Brewer Peak, Buffalo ridge and to the floor of Jim Fish Valley. The entire defensive line blocked the Holtz-Sarana and Holtz-Chichagof passes and the entrance to Jim Fish Valley.

Zimmerman sent his 2nd battalion, 32nd regiment to seize a high plateau to the left side of Jim fish valley. Again, before his men charged up the plateau, artillery made sure to pound the area, and again the Americans would find mangled survivors. At this point the Japanese situation was dire. They were desperately low on food, isolated and fighting a battle of attrition against an enemy enjoying every advantage. Yamasaki and his men were trapped behind their innermost defensive perimeter, but his delaying action left him in possession of a defensive firepower more concentrated than before. Despite the hundreds of casualties they had suffered, Yamasaki now counted with more soldiers to defend each yard of ground.

May 23rd began with a heavy fog and very snowy weather, preventing Zimmermans men from launching their main attack. He was only able to send the  2nd Battalion, 17th Regiment and 2nd Battalion, 32nd Regiment to relieve the exhausted 4th Regiment. Company A of the 4th infantry had a horrible experience when 9 Japanese machine gun nests with attached riflemen pinned them down. Then an unexpected event occurred as told to us by Lt Winfield Mapes “quite suddenly a lone figure jumped up and ran across the open snow towards the nearest Jap hole. He had an M1 and bunch of hand grenades. He threw a grenade into the first hole and began firing. He moved right on into the circle of Jap holes around the machine gun. Deliberately, he walked up the edge of the holes one by one, […] then […] tossed a grenade. Nine times he did this […] [Private Fred M.] Barnett is just a guy […] who said, “Hell, I just got all fed-up and disgusted; and decided I'd get the damn thing over with,” and voiced the words of a nation” When Barnett reappeared he walked calmly downhill signaled the two companies to advance. Barnett had charged nine successive Japanese emplacements, wiping them all out without taking a scratch. Private Barnett received the distinguished service cross for his actions. 

Other smaller units probed the ridge, but all were stopped by Japanese resistance on Buffalo Ridge. To the west, Culins men were pressing towards a junction beneath Fish Hook ridge, finally linking up again with the southern force, planning to coordinate an offensive the next morning. That day, General Butler’s P-38 Lightnings intercepted a wave of 16 Betty’s managing to shot down 9 of them while losing 2 Lightnings in the process. Because of these large losses, the Japanese would not commit anymore airforces from Paramushiro.

On the morning of May 24th, a coordinated assault against the ridge began. The 2nd Battalion, 17th Infantry of the Southern Force moved over the southern slopes of Prendergast Ridge, while the 3rd Battalion, 32nd Infantry, plus two companies from the 1st Battalion, 32nd Infantry, advanced along the northern slopes. Heavy Japanese machine-gun fire, repelled both forces back to their lines of departure on Prendergast Ridge as they attempted to negotiate their way across the “Bahai Bowl.” The 2nd Battalion, 32nd Infantry Regiment and 3rd Battalion, 17th Infantry Regiment advanced up Jim Fish Valley where Japanese fire from Buffalo Ridge halted them near the southern end of Lake Cories.

The Americans were fighting for every inch of snow and ice covered muskeg they advanced upon and the casualties were mounting heavily. Dr.Tatsuguchi’s diary tells us“Naval gun firing, aerial bombardment, trench warfare, the worst is yet to come. The enemy is constructing a position. Bn. Commander died at Umanose [Fish Hook Ridge]. They cannot accommodate their patients. It has been said that at Massacre Bay district, the road coming through sector unit headquarters is isolated. Am suffering from diarrhea and feel dizzy.” Aerial and artillery bombardment was carried out the entire day, unfortunately a bit too much so, as some friendly fire occurred, yet again the fog a constant enemy. Eventually Landrum was forced to order the 4th regiment to reinforce the southern advance because of the intense resistance. By the end of the day two companies of Culins 3rd battalion, 32nd regiment managed to get into the Holtz-Sarana Pass. 

Meanwhile the American Engineers had built up the road to Engineer Hill allowing Landrum to order every artillery piece available to be brought along it up to Massacre Valley. On the 25th, artillery and aerial bombardments soften up the approaches for the 3rd battalion, 32nd infantry on the left and the 2nd battalion, 17th regiment on the right against the pass. While this assault began, the 2nd battalion, 32nd infantry and the 3rd battalion, 17th infantry resumed their assault but were met with intense resistance from the Japanese along Buffalo ridge. The defenders as usual enjoyed extremely good concealment, utilizing fresh snow to their advantage making them practically invisible. The 2nd Battalion, 17th Infantry supported by the 1st Battalion, 4th Battalion charged through snow and bullets, seizing Newman Peak, which overlooked the pass. By nightfall, Zimmerman controlled the base of the ridge with some isolated slopes in the hands of scattered companies. It was at this point the logistics for the Americans took a turn for the worse. They were not much further from their beach landings areas and the supplies were trickling up slower and slower. This was an indication that time was of the essence, the longer the battle went on, the more the chances were that logistical issues would strangle them.

When May 26th rolled around, with it came some clear weather giving the American airforces a chance to bomb the defensive lines with rare precision. Again from Dr. Tatsuguchi’s diary we receive this “Hit by naval gun firing, it felt like the Missumi barracks blew up and things lit up tremendously. Consciousness becomes vague. One tent burn down by a hit from incendiary bombs. Strafing planes hit the next room, two hits from a 50 caliber shell, one stopped in the ceiling and the other penetrated. My room is an awful mess from sand and pebbles that have come from the roof. First Lt. from medical corps is wounded. There was a ceremony to grant the Imperial Edict. The last line of Umanose [Fish Hook Ridge] was broken through. No hope for reinforcements. Will die for the cause of Imperial Edict.” Culin sent forces to secure the Holtz-Sarana Pass gradually pushing back the concealed defenders, foxhole by foxhole. Company K advance up a 2500 foot crest of Washburn Peak and found themselves face to face with Japanese trenches. Private Joe Martinez with his rifle in hand decided to walk into the enemy fire as he tossed grenades killing 5 Japanese. He managed to reach the crest of the ridge before collapsing from a mortal gunshot wound he received over 50 yards further down the hill. He was posthumously awarded with the medal of honor, the only one earned on Attu. The Northern force eventually overwhelmed the Japanese snow trenches and seized the northwestern portion of Fish Hook.

The only remaining obstacle now in the war were the trapped Japanese upon Buffalo ridge. The 4th regiment advanced along Fish Hook ridge, pushing the Japanese all the way to the summit of West Peak by the end of May 26th. The next day the weather turned around on them, with frigid slush like weather and the typical foggy concealment aiding the Japanese. Yamasaki took the advantage by dispatching reinforcements. Zimmerman’s reinforced the advance against Buffalo ridge, tossing the 2nd battalion, 32nd infantry and companies C & D from the regiments 1st battalion alongside a lot of artillery support. But yet again the Japanese held firm, successfully halting the American advance just 200 yards from the ridges crest.

On the 28th, another assault was launched against Buffalo Ridge supported by artillery. This time, the 2nd battalion, 32nd regiment managed to reach the top of the ridge facing significantly less resistance. Yard by yard the Americans seized most of Buffalo ridge by the end of the day. While that was going on, the forces advancing along Jim Fish Valley reached the southern portion of Lake Cories where they established a defensive position to hold up for the night. Landrum expected the 29th to be the final offensive to take Chichagof. The Americans now dominated the high grounds. The 1st battalion, 17th infantry held the Holtz Bay area; the 3rd battalion, 32nd infantry were atop Fish Hook Ridge; 1st battalion 4th infantry held positions along the Holtz Bay-Sarana Pass and atop West Peak; the 2nd battalion, 17th infantry and 1st/2nd battalions of the 32nd occupied Buffalo Ridge; and the 3rd battalion, 17th infantry held Jim Fish Valley. 4 75mm mountain guns and a battery of 105mm howitzers were placed on Hogback ridge while 60 artilleryman took up spotting positions on Engineer hill to direct the bombardments. Everything was in place for a final battle. The Japanese had their backs to the sea, crammed into a crowded area of low flat ground counting only 800 soldiers left. Two Japanese soldiers had been captured a day earlier and they confessed the remaining strength of their garrison. This prompted Landrum to order leaflets dropped over the Japanese positions. The leaflets carried a message from General Landrum to Colonel Yamasaki informing him of his hopeless situation and asking for his unconditional surrender. Landrum also added in “that the Japanese soldierly conduct thus far had been worthy of the highest military tradition”. Landrum asked Yamasaki to send a delegation to the American lines under a white flag. Landrum was trying to avoid the senseless slaughter, hoping Yamasaki might prove himself to be different from the countless other Japanese commanders who chose to resist to the last man. Landrum also was trying to prod the common Japanese soldiers to see if they would surrender in the face of the inevitable. Yamasaki ordered all paper burnt and personally oversaw all his wounded men given a fatal dose of morphine and their comrades showered the dying men with grenades.

The Japanese, knowing full well the submarines originally set to come rescue them were no longer coming, the American destroyer picket line was preventing this. There was nowhere to pull back to, but the Japanese did not surrender, no Yamasaki chose to go out in a blaze of glory, fit to make the late Saigo Takamori proud. Yamasaki took his ancestral katana, while his men fixed bayonets. They were going to banzai charge at the weakest point in the American lines during the night, the Jim Fish Valley floor. They hoped this suicidal thrust might see a breakthrough upon which they could charge towards the American position at Engineer hill, hoping to capture their artillery to bear down upon them and to destroy their supplies. If they could manage to destroy the american supplies, they could theoretically then flee into the southern mountains where they might delay the americans enough to be rescued.

The slim hope of victory depended on lightning speed, defeat would see their complete annihilation. By nightfall Yamasaki got his men ready, the 1st company and remnant of the other 2 companies of the 303rd independent battalion took the left flank, Yamasaki, his HQ and non-combat forces too a rear position and the remnants of the 83rd independent battalion took the right flank.

In the early morning of May 29th, nearly a thousand screaming Japanese charged, as described by Nisei interpreter Peter Nakao later on “ It was pitch black when the enemy began the banzai attack. […] All of a sudden, the enemy was upon us. We could not see anything in the darkness except for tracer bullets flying in every direction. […] Leaving bayonetted dead and wounded behind them, the Japanese went past us and continued to the medic unit station to our rear. Then they headed for the ammunition dump behind the medics”

The Japanese had smashed into the reserve Company B, 32nd regiment. The inexperienced men of that company had set up camp dead-center in Chichagof Valley, and had also withdrawn to the rear during the night to make breakfast, so their deserted positions where quickly overwhelmed and they fled for their lives to Buffalo ridge. Yamasaki let them flee and took his men in the direction of Engineer Hill. Yamasaki’s timing was brilliant, he had taken the Americans by surprise and his forces were sweeping up the base of Engineer hill easily getting past the enfilading fire from the ridges by daybreak. The Japanese savagely swarmed a field hospital, exterminating all the sick and wounded men inside along with its chaplain. 12 Americans in a tent outside survived the horror by pretending to be dead, though they were severely trampled upon twice by charging Japanese.

At this point the American initial shock and panic had worn off and General Archibald Arnold rallied the men. He set to work organizing artillerymen, engineers and service troops to establish hidden defensive positions. They lacked automatic weapons, but the ragtag force consisting mostly of the 50th engineers met the charging Japanese with grenades and M1 Garand bullets. Eventually the 4th regiment came forward with automatic weapons successfully slowing down the Japanese banzai charge. The Engineers then fixed their bayonets and engaged the Japanese in hand to hand combat forcing them to fall back. Yamasaki was gunned down by an M1 Garand bullet and his men were unable to maintain the momentum. Nearly half of the Japanese, now isolated and surrounded began pulling the pins of their grenades as they held them to their chests, 500 men committed suicide en masse. Several Americans witnessed the Japanese squatting in a thick shadowy cluster in the first weak gray light of morning  seeping through the fog, with one man standing and appearing to speak to the others. The thumps of their detonating grenades and agonized cries of dying men created a crescendo, that died away leaving the grounds littered with disemboweled bodies. American reporter Robert Sherroid described the scene as such “The explosive charge blasted away their vital organs. Probably one in four held a grenade against his head. There were many headless Jap bodies between Massacre [Bay] and Chichagof. Sometimes the grenade split the head in half, leaving the right face on one shoulder, the left face on the other. […] Two bodies were burned to crisps, one atop the other, fused into one charred hump” After the battle was over, the Americans erected a wooden interpretive sign at the foot of Clevesy Pass honoring Yamasaki, a rare gesture considering the intensity of the war at the time. 

The battle of Attu was done. The Americans found and interred 2351 corpses, but guessed hundreds more Japanese bodies were buried all over the place. They took 28 prisoners in all, mostly men knocked unconscious by shell explosions or too badly wounded to kill themselves. Scouring the landscape over the following days, a few dozen more Japanese were found hiding in foxholes, often in small groups. The US soldiers called upon them to surrender, but these men usually killed themselves with grenades or opened fire to receive a bullet back. Two Japanese gave themselves up willing however. One was from San Francisco, the other, a short, fat and good humored man dubbed “the Japanese 8-ball”, by the GI’s was treated kindly and even allowed to eat in the mess tents. PFC Howard Sparrs described the 8-Balls capture as such “ [Private Emerson] Burgett pulled out a Jap battle flag which he held up in front of the little fellow. The Jap shook his head violently in the negative and gestured so not a doubt remained – “Take it away!” The inner pockets of his coat revealed an assorted, and incidentally excellent, collection of […] pornography […] on silk handkerchiefs. The little Jap smiled innocently as Burgett gazed appraisingly over the collection (which, by the way, he pocketed)” 

The Japanese lost approximately 2850 men dead, the Americans had 549 deaths, 1148 wounded and around 2100 evacuated due to frostbite, trench foot, hypothermia and other ailments. A number of lessons were learnt from the battle, including new landing techniques, and the necessity for rubberized, thoroughly waterproofed boots. Can’t express the importance of that last one enough, I once got a black toe in my stupid youth drinking outdoors with some friends in like -35 degree weather in bad boots, does not end well. The men on Attu had been given expensive, thick and insulated leather hunting boots, but these become absolutely useless once soaked in water. After Attu, improved winter kits emerged, and cases of hypothermia, frostbite or trench foot would become very rare among American soldiers even during bitterly cold campaigns in Italy and France.

The bitter and bloody and cold campaign for Attu was now finally over. Colonel Yamasaki decided to go out in a blaze of glory with his men, in a fashion that would make the last samurai Saigo Takamori proud.
