- 107 - Pacific War - Fall of Wareo , December 5-12, 1943

The Pacific War - week by week

Last time we spoke about the learning process after the success, a very bloody one at that, of Operation galvanic, the continued operations in New Guinea, Bougainville and the naval battle of Cape St George. Galvanic was an extremely bloody experiment, one that would teach the allies bitter lessons of what to expect from the new phenomenon of “island hoping warfare” against the Japanese. On Bougainville, Japanese roadblocks were crushed and the Americans were extending their perimeters and advancing further inland. The IJN sought to help the IJA bolster Buka and this led to an absolutely disastrous engagement against Captain Burkes destroyer squadron. Burke won a near flawless victory. Then over on New Guinea, after the seizure of Sattelberg, the Australians were now beginning a new offensive heading north along the eastern coast. The Australians were in hot pursuit of the fleeing Japanese.

This episode is Fall of Wareo

After their latest defeat at the battle of Sattelberg, Lt General Shigeru Katagiri had his men begin the long retreat towards Madang. In response General Wootten launched a two pronged offensive aimed at Wareo and Gusika. By the end of November they captured Gusika with ease effectively cutting off the Japanese supply route to Wareo. “All that remained of the 20th Division in this area consisted of abandoned foxholes, entrenchments, ammunition and ration dumps, equipment, weapons, camps, medical aid posts and graves.” The advance continued, on December 1st, the 2/43rd’s tanks were blasting through Horace’s Ears. The tanks blasted out the light opposition and soon the 2/43rd were occupying Horace’s Jaws, Nose and Western Ear. Meanwhile the 2/15th attacked Nongora, but were unable to defeat its defenders and had to pull back. A company of the 2/23rd smashed the last line of opposition south of Kunako village allowing for its seizure. Over at the Kalueng river, after a artillery bombardment, the 2/28th sent Lt Rooke’s with a patrol to check out the Lagoon who advanced without any opposition. Later in the afternoon the Australian scouts pushed south around 600 yards and began to hear the sounds of digging and chopping. They killed a Japanese and wounded another advancing further southwest to avoid what was assumed to be an enemy position. Towards dusk a strong Japanese patrol ran into them causing a small firefight. Rooke had his men dig in for the night while he climbed up a tree to observe the Japanese northeast of them. Rook then sent two volunteers, Privates Hutton and Wadel to try and slip back to the battalion HQ to get help, both men were killed trying. At 8pm Rooke’s patrol snuck out under the cover of rain and darkness to dig in closer to Kalueng.

On December 2nd, while the 2/43rd consolidated all of Horace, they also began advancing towards the Lakes against slight opposition. Then some of the tanks were attacked by Japanese 75mm guns from atop some high ground to the north of a lake at around 200 yards. The 2/15th would find Nongora abandoned on the 2nd and seized what was once the 79th’s regimental HQ. At Kuanko, patrols of the 2/23rd would find the Japanese held a formidable position along a ridge near Peak Hill. At 8:30am the Japanese began firing machines guns upon the Kuanko area, only to be replied with Australian mortar and artillery. At dusk the Japanese suddenly charged using bombs made of gelignite that caused large blasts, but did little damage. The Japanese charge had surprised the forward Australian units who pulled back, thus the Japanese were able to seize ground north of Kuanko. It was a serious situation, so the Australians decided to launch a night attack. The leading platoons lost several men while charging the Japanese throwing grenades and explosives. The men of the 80th regiment however held their ground and repealed the Australian assault inflicting heavy casualties upon them.

For the past two days, Brigadier Edgars three battalions had been receiving training from AIF battalions about jungle fighting. Wootten then decided to attach AIF experienced jungle fighting units to Edgar’s battalions in an advisory role. Now the 20th, 24th and 26th brigades would each supply the 29th/46th, 37th/52nd and 22nd battalions with teams consisting of 3 officers, 9 NCO’s, 9 Privates all capable of leading sections. These men would be advancing up the coast towards Fortification Point, with the 20th brigade held back in reserve. To support this advance a new beachhead was required at the mouth of the Kalueng to supply them by sea. Men went to work removing all the underwater and hardwood obstacles, so a bridge could be built over the Kalueng to allow the tanks and jeeps to cross. Edgar sent the 22nd battalion on the 3rd to capture some high ground north and west of Gusika to secure the new beachhead. At 10:15am, Captain McFadden, Guild and Martin led companies across the Kalueng to assault some features held by Japanese. They were held back by heavy machine gun fire and quickly called in artillery support that blasted the Japanese positions until 12:45pm. After that the companies continued their attack, but without success. Then Guild’s company seized a knoll around a mile northwest of Gusika while Martins company pushed frontally and McFadden’s formed a circle around the Japanese. By 5pm the companies and artillery managed to dislodge the Japanese allowing the 22nd battalion to establish their bridgehead.

However the following day for the 22nd battalion would not be an idle one. A mixed force consisting of the 238th battalion, 33rd independent engineer regiment and 2nd battalion, 26th field artillery led by Major Tashiro had orders stating "the force, while avoiding any decisive engagement, will carry out successive resistance to try to delay enemy advance". The 22nd battalion had fought hard to clear the enemy positions south of the Lagoon, but their successes were few. Patrols discovered the enemy had dug in near a creek half way from Kalueng to the Lagoon. At 12pm, one of McFaddens platoons found a mine field along a track before being attacked. McFadden requested artillery support, but it failed to hit the mark. Lt Holdworths leading platoon 5 found themselves fighting hand to hand combat with some Japanese near the same track. Soon multiple platoons converged into the area forming an incoherent skirmish, while the Japanese enjoyed well established dug-in positions to face off against the multiple Australian groups. Because of the disorganizations, none of the Australian units managed to penetrate the Japanese positions.

Over along the track to Wareo, Brigadier Porter worried his 2/43rd battalion was too worn and torn, so he ordered two companies of the 2/32nd led by Colonel Scott to head up to bolster their strength. By the 3rd of december, Colonel Scott’s men began arriving to cover the 2/43rd, who were engaged in battle with multiple disabled tanks. By midday the Japanese could no longer withstand the Australian attacks and were forced to pull back 100 yards. Now Colonel Scott took command over the Lakes area, deploying his men and those of the 2/43rd up the main track half way between the Lakes and Christmas Hills. Back at Kuanko, the 2/23rd battalion were clinging on to their unfavourable position, being battered by the Japanese all the while. They were suffering from a lack of supplies, which were painstakingly being brought to them all the way from Palanko by men of the 2/24th battalion. Kuanko was seeing a firing duel involving numerous Japanese snipers, prompting Brigadier Whitehead to reinforce the position with Captain Denny’s company of the 2/24th.

On the 4th, Colonel Scott resumed the attack against the Lakes area with both his 2/32nd and 2/43rd companies becoming “exhausted and culled of semi-sick personnel”. Beginning at 7am the 4th and 24th batteries bombarded the Japanese positions along the track, an hour later this was followed up by 3 inch mortars. The Australian companies advanced parallel to the track over rough terrain, some managed to get 800 yards behind the Japanese where they began digging in. Despite being cut off the Japanese continued to resist until the cover of night allowed them to withdraw. To the west the 2/15th advanced north against Christmas Hills, but the terrain was so bad they eventually had to pull back to Nongora. At Kuanko, the 2/23rd discovered that elements of the 80th regiment had hooked around their rear during the night and were most likely trying to cut off their communications. Whitehead ordered the 2/24th company to clear the track. The 2/24th company advanced cautiously, going 75 yards south of the 2/23rds position near the main track. They began to dig in as patrols fanned out who quickly found the enemy occupying a track between Kuanko and the 2/23rd. They left the enemy unmolested for the moment as other patrols were sent to cut the Wareo-Kuanko track around Peak Hill linking up with the 2/23rd.

The next day with enough supplies carried forward, Whitehead sent the rest of the 2/24th to reinforce the flanking maneuver going west of the track between Kuanko and Peak Hill. Colonel Scott had his 2/43rd and 2/32nd advance towards Christmas Hills who only found dead men of the 79th and 80th regiment as they had pulled out during the night. There was a ton of abandoned equipment, rifles, anti-tank ditch and dumps of 81mm mortars. The men quickly dug in as some men were sent forward to try and outflank the Japanese who were just 50 yards or so beyond their new positions. The Australians found the Japanese had dug in on another ridge close to the track. On that same day, the bridge over the Kalueng was finally finished allowing the 4th brigade to advance to Fortification point, with Lt Colonel Kenneth Cusworths 29th/46th taking the vanguard. With three matildas in the front the vanguard advanced at a good pace through sporadic Japanese fire. At 10am the leading tank was disabled by a landmine south of the creek with its tracks blown off. The other two tanks were unable to cross the creek without engineering aid leaving the vanguard force to advance unsupported. Several abandoned positions were passed before they ran into significant enemy fire. Cusworth’s men were held up at the line of the first creek where the terrain turned into a large kunai field then jungle. By the afternoon the tanks were repaired and helped cross the creek, successfully brushing aside the enemy resistance allowing the Australians to advance halfway to the Lagoon. But the 238th regiment’s companies regrouped and began attacking the advancing columns using sniper fire. This eventually caused Cusworth to order his men to pull back 60 yards to dig in near the creek.

Though the tanks were essential at pushing away the enemy, they also were causing significant delayed as they continued to run into tank ditches and mines. On December 6th, Cusworth resumed his advance along two tracks leading to the inland side of the Lagoon. Woodpecker and light machine guns pelted the Australian columns inflicting heavy casualties. On the left track the Australians fought a Japanese position upon Bald Hill near the northern end of the Lagoon. The leading platoons had to charge through artillery and machine gun posts, but they managed to dislodge the Japanese who were hastily fleeing. The Japanese fought like lions, but there was little they could do against superior artillery and tank supported infantry. The best the Japanese could hope for was to continuously fight delaying actions while trying to avoid decisive engagements.

General Katagiri lacked manpower, supplies even physical strength to fight the advancing Australians off. His units in the mountain and coastal areas were essentially cut off from the frontlines. The were relying heavily on Submarines and barges to move the meagre supplies that came from sea, and these were at the mercy of PT boat patrols. Overland the Japanese were failing to recruit native carriers because the Allies were extremely successful at bringing them to their side. Katagiri had no choice he ordered a gradual withdrawal from Wareo, lest it become a massacre. The 79th regiment began pulling back towards Lakona to reinforce the coastal area.

Colonel Scott ordered an artillery bombardment to kick off December 6th before sending his men to assault Christmas Hills. His men were able to easily seize the eastern slope near the top, but now faced Japanese defensive lines on the western slopes less than 100 yards away. Colonel Hayashia received orders to abandon the positions during the night and as was becoming a routine, Scotts men found them abandoned the next morning. Meanwhile the 2/23rd discovered the enemy in front of them had likewise pulled out during the night. The 2/24th began cutting the track between Kaunko-Kwatingkoo and Kuanko-Wareo. During the afternoon the 2/23rd and 2/24th coordinated an assault to take Peak Hill. The 2/23rd performed a diversionary attack at 5pm using 25 pounders as the 2/24th stormed Peak Hills western slopes. By 6:45 the 2/24th were digging in on the western slopes and when darkness fell the 80th regiment began withdrawing from Peak Hill, allowing the Australians to seize the feature entirely by the morning.

At this point the 2/23rd passed through the 2/24th position to hit the last Japanese defensive positions located 600 yards away from Wareo. Along the way the 2/24th discovered that Kwatingkoo was still held strongly by the enemy. The village still had at least 4 machine gun posts and mortars. The Japanese were only performing delaying actions as by December 8th the mountain area was finally abandoned altogether. The 2/24th occupied Kwatingkoo and the 2/23rd Wareo, quickly hoisted the Australian flag on the high ridge in the area. The fighting had cost the Japanese 451 dead, with 1 captured. For the Australians, they suffered 47 dead and 322 wounded. Knowing the Japanese were just going to take up more defensive positions, the 2/24th were ordered to pursue them as quickly as possible towards Bazuluo and east of the Christmas Hills area. The acting Japanese rearguard, units of the 2nd battalion, 79th regiment took up a position at a 2200 feature ambushing the Australians at every point possible. The Japanese rearguard would perform a delaying action against the 2/24th and 2/32nd battalions until December 12th, gradually pushed northwards. Their efforts earned them severe losses, but also valuable time for Katagiri to pull the forces back and assemble new positions.

On December 7th, Cusworths men were held up by heavy fire coming out of an enemy position halfway between the lagoon and Tunom River. Cusworth men had advanced far past their tank support who were continuously being bogged down by mines and tank ditches. Regardless, the Australians still enjoyed superior artillery support and continued their pursuit of the Japanese until they reached the Tunom by nightfall and dug in. The next morning, Cusworth ordered the forces to cross the river, but the 238th regiment had companies take up positions to hit them as they did. Well concealed Woodpecker guns unleashed havoc from the jungles upon the advancing Australians causing heavy casualties. The Japanese were desperate to delay the advance as much as they could to give their men a fighting chance to withdraw. Sniper fire and Woodpeckers were all they could toss back, but the Australian artillery was able to pinpoint and annihilate their positions systematically.

Along the Australian left flank, the 37th/52nd were fighting their way towards Tunom, with one company managing to get across the river against fierce resistance. During the night the Tunom defenders pull out allowing Cusworth to advance towards the mouth of Tunom by November 9th. The next day saw the 37/52nd in a very dangerous position. They were under heavy fire including artillery and it was likely the Japanese would perform a hook to cut them off. Brigadier Edgar decided to toss his 22nd battalion into the center line. The 22nd battalions advanced to a creek junction and unleashed a large mortar bombardment and upon advancing further only found dead Japanese. Along the rest of the advancing line the men were facing less and less resistance, as most of the 79th regiment were nearing Lakona.

Cusworths men accompanied by the 29th/46th and some tanks advanced further and reached the Sowi river by 1:40pm. With heavy artillery and tank support they continued on until 3pm when they found Kilingia recently abandoned. The Engineer special brigade amphibious scouts rolled up to the Kiligia area and went to work forming a new beach head. This led to a new group constituting of AASC, medical and ESB detachments being brought up by landing crafts who constructed jeep tracks to help the infantry come over and to alleviate native carriers. The Australians did not rest however, the next day saw them continue the advance, with one company of the 22nd crossing the Sowi before digging in for the night. On December 12th, the rest of the 22nd crossed the Sowi with their tank support dispersing meager Japanese resistance. The 22nd advanced over numerous creeks where Japanese took up positions. By the 14th, the 22nd managed to force the Japanese back away from the 5th creek they came across. At this point the remnants of the 238th regiment withdrew to Lakona joining a garrison forming there and sent 50 infantry towards the Masaweng River to help Hayashidas rearguard. The 37th/52nd advancing on the left flank were meeting stiff resistance, but the Japanese rearguard could do nothing against their artillery and mortars. Now the 22nd were approaching a creek near lakona and began clashing with the growing garrison in the area.

The Japanese had dug in forming a strong position, but a company of the 22nd led by Howieson hooked around a cliff trying to block the Japanese escape route. While this was going on the 37th/52nd were pushing back the rearguard forces towards the fringes of Cape Sibida. The 50 Japanese there found themselves surrounded because of Howieson’s men and had no choice but to fight to the last man. Howiesons men from the cliff position tossed grenades down upon them to horrifying effect. At 5:30 on december 16th, 5 matildas rolled in towards the Cape Sibida pocket finding the doomed Japanese with their backs to the sea. At a range of 150 yards they began to fire upon the Japanese and with 8 minutes reached the cliff where they mopped them up to the last man.

After further investigation it would turn out many Japanese had leapt off the cliffs around Cape Sibidia rather than die to the enemy. For the next day several stragglers were shot, including a few men who tried to swim out to sea heading for Sanga. 47 dead Japanese would be counted by the end of the 17th, though it was likely there were 70 or more. On the 17th, 14 more Japanese would be killed sheltering in some caves below Cape Sibida, it is theorised this was the area men had lept to the deaths. It was a decisive day, the Japanese had fought fanatically, but had lost Lakona, the pivot to their escape route. The next day the 29th/46th advanced along the coast and crossed the Sanga under a heavy artillery bombardment. The resistance from here on seemed only half hearted all the way until the Masaweng river.

Once at the Masaweng, remnants of the 238th regiment launched a counterattack forcing the Australians to dig in for the day. It seems it was the last ditch effort to delay the advance of the 4th brigade as both the 29th/46th and 37th/52nd battalions were able to reach the Masaweng unopposed on the 18th. On the 18th, Katagiri received orders from Generals Imamura and Adachi to officially cancel further operations to take back Finschhafen and to withdraw towards Sio, the very last key position on the west coast of the Vitiaz strait. For the new task at hand, Katagiri sent the 80th regiment to occupy the Ago-Kanomi area and guard the coastal area to allow the rest of the division to withdraw towards Kalasa and Sio. The rearguard would be provided by Colonel Hayashida’s 79th regiment.

The 19th brought an intense artillery barrage as Cusworth’s men were hitting Hayashida’s main line. The Australians were met with a strong rain of fire and were unable to break through. Only the matildas were able to make some progress, but they were quickly held back by a steep ravine. On the left flank the 37th/52nd crossed the Masaweng unopposed during the day and marched to the southern slopes of FOrtification Hill by nightfall. This action forced Hayashia to withdraw during the night, the unpleasant routine his men had endured for days at this point. Facing no further resistance the 29th/46th and 37/52nd battalions occupied Fortification Hill. The 4th brigade had suffered 65 deaths and 146 wounded during their pursuit. For the Japanese it was a staggering 420 deaths, 6 prisoners and another 136 bodies would be found later having died of disease, malnutrition and suicide. However now we need to take a little detour over to the boys on Bougainville.

Last time we were talking about Bougainville, General Geiger had expanded his perimeter. The army troops on the left flank had reached their final inland line back on November 25th. The line was adjusted at this point. In the front were the 21st marines taking up various positions on high grounds, though a lot of the terrain was swampy. Artillery units were moved forward into better positions to support the frontline positions better. Every avenue of approach to the defensive perimeter was covered in length. Meanwhile daily patrols from platoon to company strength, fanned out of the perimeter scouring the area for Japanese outposts to the east and north. They would find countless abandoned outposts. An order was issued on November 28th that no further movements were to be carried out until December.

The line was now anchored in the north by Hill 1000 and extended southward paralleling the Torokina River to Hills 600 and 500. This denied the Japanese access to any high ground that would allow them to use artillery against the airfields and beachhead. To protect their general advance from any Japanese surprise attacks against their right flank, Geiger planned to launch a raid against the village of Koiari to the south. Geiger selected the 1st parachute battalion of Major Richard Fagan, reinforced with M Company of the 3rd Raiders. Their task was to launch a surprise attack against a Japanese position near Koiari, blow up any supply dumps they found, disrupt communications and harass the enemy as far into the interior as the East-West trail. A landing reconnaissance was carried out on November 27th, reporting no enemy anywhere near the target area, however these reports were unfortunately wrong. The paratroopers got aboard some LCM’s and LCVP’s at 4am on the 29th and would find themselves tossed nearly in the center of a Japanese supply dump. Major Fagan had estimated they would be opposed by at least 1200 Japanese, most likely the Japanese 6th transport regiment and elements of the 23rd infantry regiment.

Luckily for Fagans men, the Japanese were just as surprised as them. Fagans men quickly overran the dump and established a perimeter extending 200 yards inland. The Japanese then responded by tossing mortar, machine gun and rifle fire at the marine beachhead. Artillery from Torokina began to help the marines as they were met with a series of enemy charges through the night. The second landing party landed further south to meet up with the main party, but in the process would suffer 13 casualties. Fagan sent word to HQ that things were getting very hot and they needed to pull out quickly. He estimated 1200 Japanese would be storming his beachhead. Geiger fearing his mens annihilation quickly formed a rescue operation, though communications broke with Fagan.

The Japanese continued to toss attacks at the beachhead, but were kept at bay by gunfire from 155mm guns of the 3rd defense battalion. Meanwhile the craft used to get the paratroopers over were sent to rescue them, but they were hindered by Japanese artillery. This prompted Geiger to send an LCI gunboat and the destroyers Fullam, Lradner and Landsdowne which had just come back from convoy duties. During the night the Japanese began surrounding the beachhead firing into their perimeter. The 155mm “long toms” continued to offer a shield for the marines, barely managing to keep the Japanese pinned down. The paratroopers were running out of ammunition when just in the nick of time the boats arrived to the scene and all the boys were picked up by 8:40pm.

In the end the raid was a complete failure, the Americans suffered 15 deaths, 99 wounded and 7 were missing out of a force of 614 that went over. They estimated they had caused 291 casualties upon the enemies, but there was no way to really gauge this. Nearly all the damage dealt to the enemy was done via artillery and naval bombardment, pretty much making the raid a complete waste of time.

Over on Green Hell, the Japanese yet again found themselves on the run with the Australians biting at their heels. Wareo had fallen, now all that remained was Sio, but the Japanese would be no means make it a walk in the park for the allies. Over on Bougainville, the Americans proved once in awhile they could mess up to.
