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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

 

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

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

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

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

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

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

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

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

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

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

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

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