- 89 - Pacific War - Fall of Munda, August 1-8, 1943

Last time we spoke about the drive to Lae and Salamaua on New Guinea and the mysterious battle of the Pips. The boys on Green Hell were having a hell of a time trying to capture Mount Tambu. The Japanese had made a pillbox nightmare around Mount Tambu and reclaimed Ambush Knoll. Ambush Knoll was once again taken by the allies, by Warfe’s commandos to be exact, but Mount Tambu was proving to be a much tougher nut to crack. Then in the frigid northern waters of the Aluetians, the allies had just successfully retaken Attu, but at a horrifying cost. The heavy cost convinced the allies, Kiska would be a similar bloody affair so they sought some Canadian help for its invasion. Yet before the invasion would occur one of the strangest battle of WW2 happened, the mysterious battle of the pips. The Americans found themselves firing at ghosts. But today we are venturing over to New Georgia.

This episode is the Fall of Munda

The New Georgia campaign in many ways was akin to Guadalcanal. The Americans had suddenly invaded the island, landing numerous troops before the Japanese could coordinate a way to thwart them. Once the troops were landed, then the Japanese decided to react, and by react I mean tossing troops of their own on the island to dislodge the Americans. But just like with the Guadalcanal campaign, the war of transportation was not one the IJN could seemingly win against the Americans. By 2nd of July US forces led by the US 43rd Division, held an overwhelming advantage of 15,000 troops compared to 9,000 Japanese, who had landed at Zannana with a view to attacking westwards towards Munda Point. It was a battle that took far longer than the Allies had envisaged. Stubborn Japanese resistance and their ability to infiltrate US lines and cut supplies meant an advance at a snail’s pace, despite their control of the air and sea. Yet while the Americans were chipping away, bit by bit at the outskirts of New Georgia, the real defensive position was of course, Munda. Up until this point Major General Minoru Sasaki had done a great job of delaying the Americans while pulling his forces back to make a stand at Munda. Indeed the Americans had a terrible time fighting the Japanese and mother nature, as Sergeant Antony Coulis described one advance thus “We alternatively crawled up and down greasy ridges. We forded numerous jungle streams and swam three of them. The repeated torture of plunging into icy streams; the chopping away of endless underbrush and foliage; the continuous drizzle of rain; the days without hot food or drink; the mosquitoes tormenting us at night. It was sheer physical torture …”

Sasaki had constructed a barrage of defensive entrenchments around the airport around Munda to halt the US advance. As Admiral Halsey recalled “Rugged as jungle fighting is by now we should have been within reach of our objective, the airfield. Something was wrong.” The now deceased Admiral Isoroku Yamamoto’s plan to turn the Solomons into a killing machine in order to force the United States to parley for a negotiated peace, seemed to be working. With the battle turning into a stalemate, on 15 July Halsey sent the famously tough Major-General Oscar Griswold, of the 14th Army Corps to New Georgia. Major-General John Hester, who had turned down help from the Marines, was relieved from command of the 43rd Division and replaced by Guadalcanal veteran Major-General John Hodge.

A Landing Craft Tank Captain named Jack Johnson  described the operation as a “screw-up. General Hester was army. I had him aboard one time. He was a little fart. He wore these high lace-up boots and carried a riding crop.” However, a lot of the blame would be placed on Rear-Admiral Turner, the commander of the amphibious forces who had insisted that Hester should retain divisional command as well as overall command of the landing operations.It also did not help that the 43rd “National Guard Division” were untested in battle. Griswold would find them in a state of near psychological collapse, prompting him to request reinforcements from the 37th division.

The 37th division was led by General Beightler who was manning Reincke Ridge while to the south near the beach were the 43rd division under General Hester's command until the 29th and the 25th division of General Lawton Collins. Additionally Marine tanks of the 10th defense battalion from Rendova were arriving to replace recent losses and they would be critically needed to face the nightmarish Japanese pillboxes the Americans would be facing.

In front of the Americans was a complex of camouflaged and mutually supporting pillboxes and fortifications amidst thick jungle. These defenses dominated several high features including Shimizu Hill, Horseshoe Hill, Kelley Hill and Reincke Ridge. They were made out of crushed coral and coconut logs dug several feet into the ground, with just a small portion poking out for their machine gunners and riflemen. It was these types of defenses that had plagued Hesters assaults. Across a frontage of around 3200 yards, Sasaki had established a series of these defenses along a northwestern axis going from the beach to Ilangana. Before the offensive could be kicked off, 161st regiment led by Colonel James Dalton discovered the Japanese held the Bartley ridge due east of Horseshoe hill. Their reconnaissance indicated double-logged pillboxes. Bartley ridge would be the most forward of the defensive positions and thus needed to be seized first. 

To meet the enemy Sasaki ordered Colonel Tomonari’s forces to launch a second counterattack against whatever allied forces showed up on the northern flank and he also requested the recently landed Yano battalion to reinforce the northern flank. However Tomonari’s men had suffered tremendous casualties and he was still trying to rally the scattered men along the rugged highlands. Meanwhile Colonel Yano was only able to send his 7th company to take up a position northwest of the 3rd battalion holding Sankaku hill, because his other men were needed to defend Vila. Because of this Sasaki ordered the depleted 1st battalion, 229th regiment to reinforce the Ilangana line. Colonel Hirata placed the 1st battalion along the line between Sato’s 2nd battalion and Kojima’s 3rd, which would turn out to be a key position.

The offensive kicked off at first light on July 25th. Commander Arleigh Burke took 7 destroyers through the Blanche Channel and bombarded the Lambete plantation for 43 minutes firing more than 4000 5 inch shells. Nearly at the same time, the new commander of AriSols, Brigadier General Than Twining sent 171 bombers and 100 fighters to hit Munda, the largest air strike thus far in the area. As Burke’s destroyers were firing 5 inch shells, B-24’s and B-17’s led the air attack, followed by B-25’s, Dauntless and Avengers. It was described by many eyewitnesses as “the greatest show on earth”. The Japanese were only able to toss back 57 Zeros at 9:40am who were intercepted quickly by a Rendova patrol of 29 fighters who shot down 6 zeros and lost 4 of their own. But from 6:30-7am, the 254 aircraft managed to drop 500,800 lbs of fragmentation and high explosive bombs over the target area, a roughly 1500 by 250 yard strip. The result was enormous clouds of smoke hanging all over Munda, but Japanese casualties were considerably light.

As the bombardment was quieting down, Griswold unleashed the ground forces supported by the 43rd divisions artillery who were firing more than 2150 105mm howitzer shells and 1182 155mm howitzer shells. Colonel Brown's 103rd regiment advanced upon Ilangana point while the 172nd tried to envelop Shimizu Hill, supported by 5 tanks. The 172nd tossed their 2nd and 3rd battalions around the left and right of Shimizu hill, but by 10am, even with the 5 tanks the Japanese pillboxes had halted them in their tracks. 3 of the tanks were disabled because of vapor lock and a ton of time was wasted by infantry trying to extricate them. THe 3rd battalion on the lefthand side, tried to fight through machine gun and mortar fire, but found it impossible. The men tried to move around the pillboxes but found themselves fired upon by other machine gun positions. The 2nd battalion, 103rd regiment attacked in the center of the 43rd divisions zone and managed to progress 300 yards against lighter opposition. bY 10:40am Company E managed to advance 500 yards and by noon reached a beach near Terere. As Company E tried hastily to create a defendable position, the Japanese moved behind them cutting their telephone lines back to the battalion HQ.

Seeing the opening, General Hester tossed in some of his reserves in the form of Ramsey’s 3rd battalion, 169th regiment. They were ordered to charge through the same gap made by 3 Company. But as they marched towards the gap they were met with enfilade fire from the southern part of Shimizu hill and from some pillboxes to the south. The 169th were unable to exploit the gap and now E company was forced to pull back lest they be encircled and annihilated. To the north, Beightler kept his 145th and 148th regiments in reserve until Bartley ridge was neutralized. Dalton sent I Company to contain the Japanese pocket by attacking it frontally while the 1st battalion and rest of the 3rd battalion performed a double envelopment. The 1st battalion went around the left while the 3rd took the right, seeing both driving southward and northward for 200 yards. The 1st battalion led by Lt Colonel Slaftcho Katsarky advanced 700 yards with only light opposition, but over on the other side the 3rd battalion of Lt Colonel David Buchanan were halted at the offset by heavy machine gun fire. By the 2nd of the day the 3rd battalion would establish itself in a containing position north,south and east of Bartley ridge. E Company had to be taken out of reserve and sent into the line on some high ground due north of Bartley ridge to secure the right flank of the 161st zone. The 1st battalion advanced a further 400 yards west of Bartley and took up a position on a small rise northeast of Horseshoe hill.

With the southern advance stalling somewhat, Colonel Stuart Baxter of the 148th was ordered to help the 161st’s efforts at reducing the pocket on Bartley ridge. He performed a limited advance and his 2nd battalion led by Lt Colonel Herbert Radcliffe gained 600 yards without meeting Japanese resistance. Meeting no resistance, the 1st battalion led by Lt Colonel Vernor Hydaker took up the 2nd battalions position as they advanced further, allowing engineers of the 117th engineer battalion to construct a supply trail behind them. 

Despite all of this Griswold was frustrated by the failure of his 43rd division performance. Ultimately Griswold blamed General Hester who he wrote about in his diary that night  “I am afraid Hester is too nice for a battle soldier. He is sick and all done in. Tonight I am requesting his relief from the division.” The next day he ordered the exhausted 172nd to hold their position while the 10rd would advance 800 yards from Ilangana for Terere. To support them the artillery bombarded for over an hour, allowed the 103rd to advance with some tanks in the vanguard. A crucial component of their advance would be the 118th engineer battalion led by 2nd Lt James Olds an acting corps chemical officer, whose men were equipped with flamethrowers who went to work spilling fire over enemy pillboxes. This led to the vegetation over and around them being incarcerated in a matter of seconds and many pillboxes were simply wiped out. 

As I had said a few times in this series, the flamethrower would be one of the most devastating weapons in island hopping warfare. The flamethrower was gradually employed by both assault and mop up operations. However useful as it was, it did hold some disadvantages. The equipment as you can imagine was quite large and heavy, required the operator to get very close to the enemy positions and thus extremely vulnerable. For flamethrower personnel to be able to close the distance required rifle team protection. But what if you could alleviate these vulnerabilities by slapping a big flamethrower to a tank? Generals like Griswold and Harmon at this point began mounting flamethrowers to tanks and although it would not see the limelight at Munda, the Firetank as they would become known would become the most devastating weapon against Japanese defenses. By the midafternoon, Browns 10rd regiment managed to reduce around 74 pillboxes along a 600 yard front, successfully occupying Ilangana and continuing the coastal advance until Kia. While it was a great victory for Hester, it failed to change Griswolds mind about relieving him.

Back over in the north, Beightler ordered another assault of Bartley’s ridge. 6 light marine tanks of the 10th defense battalion led the charge at 9am. Companies L and K advanced in columns behind the tanks, tossing heavy fire from .30 caliber Browning automatic rifles (known as BAR’s for my Call of Duty world at war veterans) and 2 flamethrowers. Unfortunately for the two guys carrying the flamethrowers, they were not properly protected by their rifle teams and were killed quickly. Very much like the learning of how to perform amphibious landings, it would take time to learn how to effectively use flamethrower units. The man managed to overrun a dozen or so pillboxes, but the terrain soon forced Dalton to frantically order men to extricate stuck tanks. During the morning hours a Japanese soldier burst out of the brush and planted a magnetic mine to one of the stuck tanks disabling it. A second tank was hit in its fuel line by gunfire while the remaining tanks managed to pull back and reorganize by 11am. After 5 hours of combat, Buchanan’s 3rd battalion had lost 29 men and only progressed 200 yards and thus was forced to pull back again. 

On the 27th, Beightler committed his 2nd battalion, 145th regiment to reduce the defenders on Horseshoe hill. They managed to occupy a knoll connecting Horseshoe hill called Wing Hill, but heavy fire from Horseshoe hill eventually dislodges them. Meanwhile Colonel Tomonari finally managed to rally his men together for an attack against the 148th northern flank, while Sasaki sent a machine gun detachment, which was actually some anti-aircraft gunners to ambush the 148th engineers causing Colonel Baxter to order Companies A and D to rush over to protect them. Further south, General Hester began tossing some more aggressive actions in combination with artillery and mortar bombardments, gradually pushing the Japanese off high grounds. The 43rd division was slowly advancing yard by yard on the right flank, now reaching within 500 yards of the coast, but the 8 tanks of the 9th defense battalion were demolished in the attacks.

On the 29th, the 1st battalion, 169th regiment had to be brought over from Rendova to take up a position between the 103rd and 172nd regiments. Alongside 4 tanks from the 10th defense battalion and some engineers wielding flamethrowers, Hester now had enough hardened forces to push the Japanese. Because of the continuous fighting, all the American regiments were becoming veterans. Pockets of Japanese that would have once held back an entire american battalion, possibly even a regiment were not being reducing quickly and efficiently. The technique for reducing pillboxes, whether it be from isolating them or overwhelming them was becoming mastered. Broken down this process began with a complete non-combative reconnaissance of the Japanese defenses. This was followed up by a reconnaissance in force, usually by a platoon with extra units who would uncover a portion of the Japanese positions. The assault consisted of  parts: preparing an artillery bombardment usually consisting of mortars, firing off the bombardment, then storming in. The bombardments usually got rid of the brush and foliage improving visibility so the enemy could be targeted and damaged. If done efficiently, the Japanese would flee their pillboxes to take refuge. Flamethrowers and tanks made the process a lot easier for the finishing touch part. Soon the Japanese were being pushed to the crest of Shimizu hill. However while Hester was definitely picking things up better with the 43rd division, Griswold was determined to relieve him of command, feeling the man had exhausted himself. Now Major General John Hodge would take over the 43rd.

Meanwhile to the north, the Beightlers 161st regiment infiltrated abandoned pillboxes on Bartley ridge near its crest. Over on Horseshoe Hill the Japanese were being hit with heavy bombardments while the 2nd battalion reoccupied Wing Hill and Companies G and F crept their way up the crest of the hill. However once near the crest they began to be pinned down by machine gun fire. The 1st battalion was hitting the hill from the southeast meeting heavy fire as well and they managed to reach 15 yards on top of the crest before being halted. By 5:30pm, the 2nd battalion was forced to withdraw to the foot of the hill, but two companies from the 1st battalion dug in on the crest. The americans lost 24 men died with 40 wounded.

On the other side, during the night, Tomonari’s main forces of 400 men arrived ready to attack at dawn. They attempted to move behind the rear of the 148th as Baxter’s troops were advancing to Bibilo Hill. Baxter’s force was spread out quite thinly across 1500 or so yards and they happened to be around 800 yards west of their main regimental ration and ammunition dump. The Japanese from a high ground position began firing down upon them with machine guns, rifles and grenades as forward units stormed the rations and ammunition dump. A ragtag group of service company soldiers rush over to defend the dumb returning fire upon the Japanese. Major Frank Hipp of the 148th took command of the force managing to hold back the Japanese. However as a result of this near catastrophe, Beightler ordered Baxter to withdraw on the 29th. Beightler believed the enemy was coming through a gap between the 148th and 161st greatly worrying him. 

Back over at Horseshoe hill, Companies G and F reached the crest while E company was hitting its northern side, supported by machine gun crews from H company. The fighting for the north side resulted in hand to hand combat seeing E company make some progress. But by nightfall the 2nd battalion again was again withdrawing down the hill. The actions ended disastrously, as the men were hit hard as they withdrew down the hill taking enormous casualties and gaining nothing in the process. On the 30th, Bartley Ridge and Shimizu Hill remained in Japanese hands as Beightler and Hodge were reorganizing their exhausted forces. That morning, Baxter finally began his withdrawal, miserably under heavy rain, with Tomonari’s troops harassing them with ambushes. The ambushes caused Baxter to order the men to dig in around the supply dump and that night saw numerous soldiers dying for water begin to use their helmets as rain catchers. The next day the 148th attempted another break through, but Tomonari’s machine gun crews hammered them back towards the supply dump for another night.

At this point Sasaki received new orders instructing him to keep the supply lines to Kolombanagara secure. He elected to prepare his men to withdraw to a new defensive line that would be anchored at Kokenggolo Hill to the right, running east of Bibilo hill towards the Munda-Bairoko trail, then it would pass north to Hachiman Hill. Yano and his battalion were ordered to come over from Kolombangara to take up a position at Sankaku hill; Hirata’s 229th regiment would hold Kokenggolo Hill and Tomonari would take up a position at Hachiman Hill. These orders came after the Japanese defenders had suffered tremendous losses over days of fighting. In truth the Japanese defensive line was formidable facing the American 14th corps, and indeed the Americans had been held back for a long time. But the Americans brought terrible power, their naval, artillery and aerial bombing was constant and hammered the Japanese. By late July most of the Japanese emplacements near Munda were in shambles. Rifle companies that were typically 170 men strong had shrunken significantly, some down as low as 20 men. The 229th regiment numbered only 1245 effective men. The hospitals could not hope to care for all the sick and wounded as constant shelling rained hell from above. Aside from the sick and wounded, as a major result of the shelling, many men were suffering nervous disorders, to use the old term shell shock, but today we’d call it  Combat Stress Reaction “CSR”. To compensate for the losses, Colonel Hirata simply ordered his men of the 229th to kill 10 americans for every Japanese and to do so to the death. That’s the kind of, I guess what the Japanese at the time would call fighting spirit, something that made the Japanese armed forces during WW2 unique, perhaps rather tragically. 

General Imamura decided to reinforce Vila with the 3rd battalion, 23rd regiment and six companies to buff up the 1th and 229th regiments. This freed up the Yano battalion to take up their new position on the new defensive line. Yet still in the meantime, Japanese were still defending Shimizu and Horseshoe Hill to give the rest of the forces time to withdraw. On the 31st Major Francis Carberry’s 2nd Battalion, 161st charged up Bartley ridge finding no resistance. Then at 4:45pm the 15th field artillery began firing on Horseshoe Hill while the American forces near its crest tried to dislodge the Japanese. Again they were unsuccessful. By the afternoon Japanese were withdrawing from the Ilagana line, covered by fire from Horseshoe hill. During the night Tomonari led his men to withdraw, but a Avenger spotted his force fleeing through a valley overheard and called in an artillery strike. One of the shells hit Tomonari’s HQ killing a lot of his staff and nearly him. Tomonari’s force had to abandon a lot of equipment, but by dawn of August 1st they had managed to assemble at Kokenggolo and Bibilo Hills. His 2nd battalion alongside Hara’s quick fire battalion went into the tunnels of Kokenggolo Hill while the rest of the 1st and 3rd battalions dug in on Bibilo Hill. 

Baxter received a message over radio on the 1st of August from General Beightler “time is precious, you must move, get going haste is essential”. The order was to get every man Baxter had and take Shimizu hill. Baxter rallied Companies A, E, B and G into a skirmish line with bayonets fixed and charged at 850am. By 9:30am the exhausted Americans reached Katsarsky’s position where they handed the weary men fresh water and some hot food. Shimizu hill was theres. Meanwhile the 103rd regiment began their own attack. Hodge sent Companies E, F and G to march upon Lambeti which they did, finding no opposition. The rest of the 43rd found no opposition as they marched across Shimizu Hill, by 3pm they advanced 700 yards. Beightlers men captured Horseshoe Hill without firing a shot and as darkness fell on the 1st of august, Griswold ordered a general advance for the next day. Admiral Wilkinson brought a convoy bearing fresh troops of the 27th regiment to aid Beightlers right flank, but it took them until August the 3rd to get into combat assembly.

In the meantime August the 1st would bring with it a significant increase in artillery bombardment. The 43rd divisions artillery commander, Brigadier General Harold Barker fired 2000 rounds on the 1st, followed by 2000 more on the 2nd, an incredible 7300 rounds on the 3rd and 3600 on the 4th. The Munda area was turned into an inferno. Yano lost the commander and all platoon leaders of the 8th company; 5 officers died atop Bibilo hill; Hara Masao was killed leaving his 1st battalion to be commanded by Sato on August 2nd; the tunnels of Kokenggolo Hill were one of the few safe planes, but a direct hit collapses an entrance to Sato’s tunnel, burying him along with 60 men, requiring an entire day to dig them out. The Japanese were forced to take refuge wherever they could, preventing Sasaki from stabilizing his new defensive line. Captain Sugiura Kaju brought reinforcements from the 7th and 8th combined SNLF to Erventa where he loaded up the 3rd battalion, 23rd regiment to head for the Vella Gulf under the escort of Admiral Nishimuras cruisers Susuya, Chokai, Kumano, Sendai and destroyer Amagiri. However the naval force was intercepted by PT boats near the Blackett strait. The PT boats fired torpedoes at the Japanese destroyers, but none hit a target. Sugiura was able to land the reinforcements around Webster Cove, but the Amagiri rammed PT 109 just forward of her starboard torpedo tube ripping away the starboard aft side of the boat. Two men were killed, and one John F Kennedy, yes the future president was tossed around the cockpit of PT 109. Kennedy got the rest of the men to abandon ship around 11 in all. A few of them had serious burns and they were forced to swim for an islet 3.5 miles away known as Plum Pudding Island. Kennedy was the first to reach the island and he proceeded to help tow others to the island. The island was unoccupied, but a company of Sasebo 6th SNLF were nearby on another islet called Gizo. Seeing Japanese barges moving around, the Americans would make their way east to an island near Ferguson passage called Leorava island. It would not be until the night of August 7th when the coastwatch Lt Reginald Evans found them and helped them reach PT 157. For his courage and leadership Kennedy received the Navy and Marine Corps Medal alongside a purple heart for injuries he suffered. However the medals would pale in comparisons to the story written about the event by John Hersey for the New Yorker and Reader’s digest which would give Kennedy a strong foundation politically. 

Back to the battle, on August 2nd, Griswold’s forces advanced across the entire front and by the late afternoon the 103rd regiment had already reached the outer taxiways of Munda airfield; the 169th were approaching Bibilo Hill; and the 37th division were 700 yards ahead of Horseshoe hill. By the end of the day, the Japanese defensive line was basically Kokenggolo to Bibilo Hill and the Americans were closing in on both. The 103rd and 169th had units around the eastern end of the airfield, many men using wrecked Japanese aircraft as defendable positions. The 145th and 161st were on the eastern ridges of Bibilo hill and the 148th were about to cut the Munda-Bairoko trail. The Yano battalion’s position was taken so quickly, the Americans had failed to notice they had overrun it. Thus Yano withdrew northwards.

On August 3rd, the general advance continued and with more open terrain present, mortars became a lot more effective speeding it up. The 169th were advancing up the eastern end of Kokenggolo Hill; to the north, the 145th were advancing up the eastern ridges of Bibilo Hill the 161st were breaking through on the right and the 148th were now along the Munda-Bairoko trail. The situation was desperate that night so Sasaki was forced to order the men to withdraw yet again, now towards Zieta. Hirata’s 229th regiment was to hold their position until sundown to give everyone time, then act as a rearguard until they could withdraw to Kongo Hill. Sasaki likewise moved his HQ to the Kure 6th Farm at Zieta. The next morning brought further misery upon the Japanese in the form of an airstrike. At 7:20am 25 Dauntless, 24 Avengers and 24 B-25’s bombed Gurasai-Kindu Point, which is just due west of Munda airfield were the Japanese had constructed fortifications and emplaced many anti aircraft guns.

Griswold did not let up seeing perhaps the final push against Munda before him. Hodge’s 43rd division with marine tanks leading the way attacked Kokenggolo Hill. Beightler’s 25th division were striking against the Japanese northern flank, freeing up the 148th and 161st to advance west towards the beach. The defenders at Kokenggolo Hill offered strong resistance as they withdrew towards Kong Hill before the 161st managed to break through to the sea. The fiercest fighting would be found on Bibilo hill, where the 145th were fighting against the dug in 229th regiment. By the end of the day, both the 148th and 161st broke through to the sea north of Kokenggolo hill and the 145th nearly cleared Bibilo hill as the Japanese fled along a trail going to the Kure 6th farm. With Bibilo Hill reduced, the Japanese began abandoning Kong Hill to continue retreating northwards. 

Griswold’s 43rd division tossed mortars, infantry and tanks across Kokenggolo Hill driving away the last of the Japanese from tunnels, bunkers and pillboxes. Their forces soon crossed the western part of the Munda airfield. General Wing grabbed a military telephone and called General Hodge from Bibilo Hill stating “Munda is yours at 2:10 today”. Inturn Griswold radioed the good news over to Admiral Halsey "...Our ground forces today wrested Munda from the Japs and present it to you… as the sole owner…" Halsey then replied with "a custody receipt for Munda… Keep 'em dying." Munda had fallen at long last. The Americans had suffered  4994 casualties since July 2nd, the Japanese had 4683 death with a untold amount of wounded.

With Munda captured, Tomonari was ordered to withdraw to Kolombangara to take command of the Vila defenses while Sasaki would move his HQ to Bairoko then move by barge to Vila as well. The 3rd battalion, 23rd regiment was deployed at Baanga island to cover the Japanese withdrawal using mountain guns. Admiral Ota’s SNLF marines were to defend Arundel island. While these forces made their retreat, Admiral Samejima elected to carry out another reinforcement run. He would transport the Mikami battalion and on August the 6th with Admiral Ijuin carrying two other companies of replacements to Buin, Sugiura was once again sailing for Kolombangara. Sugiura had the destroyers Hagikaze, Kawakaze and Arashi while Ijuin had the destroyer Shigure. Meanwhile Admiral Wilkinson received reports from a PBY that sighted Sugiura’s ships passing by the Buka Passage, so he ordered Commander Frederick Moosbrugger to depart Tulagi and sweep the Vella Gulf. Moosbrugger had the destroyers Stack, Sterret, Lang, Dunlap, Craven and Maury. He sailed south of Rendova to enter the Vella Gulf. He took his time going 15 knots to create as little wake as possible so Japanese floatplanes would not spot him and he was northwest of the coast of Kolombanaga by 11:25pm. Moosbrugger’s plan  was to divide his force into two formations; a torpedo division consisting of Dunlap, Craven and Maury, and a Gun division consisting of Lang Sterett and Stack. The torpedo group would attack first once rader contact was made while the Gun group would cut across the bows of the enemy and open fire as the torpedo’s were expected to hit.

This was to be the first time in the Solomons campaign that the US navy planned to use torpedo’s as its primary weapon. All 6 of Moosbruggers destroyers held SG radar, but much more importantly at this time an advancement had been made to fix the idiotic mark 14 torpedoes. The defective magnetic exploder was fixed and the settings that made them run too deep was fixed. Admiral King was responsible for the first fix while Moosebrugger on his own accord ordered the torpedoes to be set at a minimum running depth of 5 feet. Sugiura knew fell well he most likely did not hold the element of surprise, but he was prepared to fight as he entered the Vella Gulf with his destroyer Hagikaze in the lead. Moosebruggers force was passing through the Gizo strait before turning southeast towards Blackett strait. Then the Americans turned north up the gulf with the torpedo group leading the way during the dark hours when at 11:33 Dunlaps radar made a contact, bearing 19700 yards away.

Moosbrugger immediately changed course to close in and began to line-up his torpedo attacks. For once the Japanese lookouts failed to spot the Americans, most likely due to a lack of moonlight. At 11:41 at a range of around 4500 yards Moosebrugger fired 22 torpedoes and at 11:46 turned his ships 90 degrees as the Gun group made a course to cross Sugiuras T. aT At 11:42 Sugiura’s lookouts spotted the American ships silhouettes and torpedo wakes, but it was too late. At 11:45 7 out of the 22 torpedoes found targets. Two torpedoes hit Hagikaze, 3 hit Arashia and 2 hit Kawakaze. Hagikaze was hit aft her engine room bringing her to a stop; Arashia’s machinery spaces were destroyed and Kawakaze was hit under her bridge detonating her forward magazine sending her ablaze. Shigure would be found later to have been hit by a torpedo which failed to explode. The 3 destroyers were disabled and burning wrecks. The Japanese fired 8 torpedoes in return, none finding a target as they frantically tried to turn northwards to escape. The Gun group opened fire sinking the 3 crippling destroyers in the course of an hour killing 820 of the 940 troops on board. The Japanese would later send 4 large barges to try and rescue survivors with around 310 out of 1520 Japanese sailors and soldiers being rescued including Sugiura. The IJN received a night action defeat which also killed and prevented reinforcements for New Georgia. The American torpedoes would soon strike fear into the IJN.
