- 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.
