Last time we spoke about the mop up operations on New Georgia and the continued drive upon Salamaua and Lae. Munda had fallen, New Georgia was certainly a lost cause, but that did not mean there wasn’t come cleaning up to do. The Americans were stuck mopping up places like Arundel and Baanga seeing fierce Japanese resistance. Sasaki ordered his men to fight as hard as they possibly could while others made their way to evacuation points. Over on Green Hell, the Australian and American forces had just taken Mubo and Lababia ridge, prompting General Nakano to create a last line of defense in front of Salamaua. Now the allies had to cross the francisco river and face multiple hills, ridges and knolls. Forward units forded the francisco river and grabbed a few knolls catching a glimpse finally of Salamaua, but a glimpse was all they were going to get as the Japanese fought tooth and nail to push them back.

The time has come at last. For months, we have seen the Australian and American forces fight for each hill, ridge and knoll, cross over ravines, rivers, swamps, a green hell of a landscape filled with more horror than just the Japanese. From the Jungles of Way to the rugged mountains of bobdubi and Komiatum, through the endless rain, mud and death. Operation Postern was to finally be unleashed, landings at Lae and Nadzab would commence. Now back in August, Admiral Barbey and General Wooten were forced to postpone D-day for September 4. For Lae the plan called for two battalions of Brigadir Victor Windeyer’s 20th brigade to land on Red Beach; the 2/15th battalion would hit the eastern flank and the 2/17th to western flank closer to Lae. The 2/13th would hit Yellow beach; the 2/23rd battalion with a company of engineers, a field ambulance, a force of artillery and light anti-aircraft section would join the landing phase; the 26th brigade would follow up the initial landings and move right through the beachhead. The planners were concerned with possible Japanese naval action against their beachheads at night, as this had occurred at Guadalcanal and Milne Bay, so the defense of Red Beach would be coordinated with the 2/2nd machine gun battalion. Red Beach was selected as it was close to Lae, just a bit due east, but out of range of her large gun batteries. Yellow beach was further east and selected as an additional landing area to protect the eastern flank of the main beachhead that would be at red beach. The allies could not provide continuous air cover thus Brigadier Victor Windeyer’s 20th brigade would have to land and unload quick as all hell. The initial plans called for a time of landing known as “h hour” to be between 3am and 4am in line with Wooten’s request that it occur two hours during moonlight before dawn. They estimated they would need 9-10 hours for the unloading phase, the LST’s would then retract at around 1pm. However, when the landing date was postponed for September 4th, this changed everything. Now there would be no morning moon, thus H hour could not be scheduled until after sunrise to allow time for the allied navy to identify the correct beach on a coast that was covered by a low-lying swampy jungle terrain, there was no prominent landmarks it would be difficult. This delayed the landing until 6:30am, resulting in the loss of around 3 hours of unloading time. Alongside that came the decision to retract the LST’s by 11am as the allied air cover could not be guaranteed after 11am. This the unloading time was now reduced to 4.5 hours, that a hell of a lot less than they needed. It was also expected that the troops would take at least 1 to 1.5 hours to disembark leaving just 3 hours to unload supplies. Again logistics are not sexy, but this is the kind of problems needed to be overcome to win wars. So Brigadier David Whitehead’s 26th brigade was going to follow up the initial landings, moving straight through the beachhead with the 2/2nd machine gun battalion who were earmarked to guard red beach. Furthermore General Heavy’s brigade would dispatch some amphibian scouts with the 532nd engineer boat and shore regiment to go in on the first wave to establish red and yellow markers for the two beaches. To make things even more confusing, there was this enormous fringing reef along the thousand mile coastline with a few breaks. One break in the reef line near a village called Tauali was going to be marked Green beach as a back up landing area. The one and half mile of good narrow beach was to be Yellow beach 1, and yes there was a yellow beach 2, closer to Silimati. Admiral Barbey was going to employ every vessel he had; 4 Destroyer transports, the Gilmer, Humphreys, Brooks and Sands; 20 LCI’s, 18 LCT’s and 13 LSTs. From August 20-22nd Barbey had a full-scale landing rehearsal carried out at beaches on the south coast of Normanby island. The men learnt a few things from this experience. The first was that the surfacing of tracks with steel mesh was too slow to allow the vehicles to clear the beach. They decided that more stores would be loaded as bulk cargo and more labor would be provided to clear the landing crafts. Thus on August 29th, the 2/13th battalion was taken to Normanby island on destroyer transports were the men were disembarking from the LCVP’s up to their necks in water. There were major differences as you can imagine for the conditions in Australia vs New Guinea. As Patrick Bourke remarked ‘the country fringing the beach was the worst we had been in. Almost impenetrable jungle grew in waist deep swamps, crisscrossed by much deeper creeks.’ There was also a pre-emptive naval bombardment of Finschhafen as reports began to come in indicating enemy troops and supplies were being moved down the coast from Finschhafen by night. Vice Admiral Carpender ordered Captain Jesse Carter, commander of destroyer squadron 5 to sweep the Huan Gulf by night and hit Finschhafen. One of Carpenders staff noted ‘It will be worthwhile to prove the Navy is willing to pitch in, even if we get nothing but coconuts,”. On August 22nd, destroyers Perkins, Smith, Conyngham and Mahan departed Milne bay enroute for the Huon Gulf. This was the furthest allied vessels larger than PT boats had ventured along the New Guinea coast since the beginning of the pacific war. Early on August 22rd, they opened fire on Finschhafen, firing 540 rounds of 5 inch shells within 10 minutes before hauling ass out of there. It was the first naval bombardment of Japanese forces in New Guinea. As for the battle for the skies, General Kenney was preparing to launch a series of air raids against Lae to support Operation postern. On the day before the landing, 21 allies bombers would hit Lae Airfield to try and knock out their aerial capabilities. Now all of that was just for the Lae landing, we got an entire other operation to hit Nadzab, designated as Z-day which because of the postponement was changed to September 5th. 96 C-47’s, 82 carrying the regiments, 5 carrying artillery and 9 for supplies would be employed by Colonel Paul Prentiss’s 54th troop carrier wing to transport Colonel Kenneth Kinsler’s 503rd parachute regiment. Alongside this, Brigadier Eather’s 25th brigade were earmarked to be the first flown in after the initial landings. On August 31st tossed 3 battalion commanders, their operations and communications officers with supplies using a Flying fortress at a very low altitude over the drop zone. They were acting as a sort of reconnaissance and they would uncover vital information to ensure safe location markers for accurate future drops. Hell they even performed meteorological analysis to figure out the wind conditions for jump areas. Meanwhile they keep saying everyday here in montreal its gonna be sunny and its rained for 5 days straight. There would be rehearsals for the parachuting forces before September 3rd when the final plan was issued. Kinsler’s 1st battalion led by Major John Britten would hit field B with the task of securing the Nadzab airfield site before establishing a defensive perimeter and beginning work on the airfield. Meanwhile the Australian 2/2nd pioneer battalion led by Lt Colonel J.T Lang would cross the Markham to help construct a new airfield. Alongside this Kinsler’s 2nd battalion led by Lt Colonel George Jones was going to hit field A to capture the Gabsonkek area which would prevent the Japanese from advancing from the north or northwest. Kinsler’s 3rd battalion led by Lt COlonel John Tolson would hit field c to capture Gabmatzung and prevent the Japanese from advancing from the east. Furthermore Prentiss would drop 22 dummy paratroopers in the forests south of Yalu right where Japanese forces occupying Heath’s plantation would be able to see them. It was hoped this deception would delay advances towards Nadzab. By the way I took the time to educate myself a bit more on what is known as Paradummy’s, because honestly until writing this episode I had no idea it was a thing. These were burlap cases filled with straw and plant waste, they kind of look like sackboy to be honest. As you can imagine from ground level looking fairly high up they do look like real paratroopers and they often were dropped alongside real paratroopers to give them a fighting chance against enemy bullets. The more you know. After all the planning was done Barbey’s little armada departed Milne Bay on the morning of September 3rd. Their journey was uneventful as they disembarked at Buna for a short break before re-embarking in the afternoon. After this point Heavy’s Morobe base was hit by 9 Rabaul based Betty’s with 27 Zeros for escort which tried to high altitude bomb them, doing little damage. Because of the deceptive campaign against Salamaua, termed the Salamaua magnet, very few IJA forces were left guarding Lae. At Lae were Companies 10 and 11 of the 115th regiment to the right bank of the Markham; Company 6 of the 238th regiment at Markham point; the 2 machine gun company of the 238th regiment were spread between the Bunga river and Bulu River; the 15th independent engineer regiment, 2nd company of the 5th battalion of heavy field artillery, the 25th, 29th and 30th machine cannon companies would all be at Lae proper. Aside from the few IJA troops, Rear Admiral Fujita Ruitaro had the 7th base force, formed around the 5th Yokosuka and 5th Sasebo SNLF and the 82nd naval garrisons anti-aircraft and coastal defense units. The Japanese were having a hell of a difficult time supplying their forces at Lae. To supply the near 10,000 or so men present within the Lae-Salamaua area each month required, 150 barges carrying 1500 cubic meters of supplies. Only large type barges could manage to get through the Dampier straits rather rough sea, smaller barges were too dangerous for the task. After each passing month, the naval ships used for transports were decreasing and by May the supplies were being carried by 6 submarines, cutting the volume in half the following month. After that supplies began to be carried overland from Wewak and Madang and a new barge route was established through Sio and Finschhafen. Regardless the Japanese were barely able to keep Lae and Salamaua supplied. This saw barely 300 fit men left to guard Lae with 2650 troops, malnourished, sick, wounded or suffering tropical ailments. The Japanese did have some big guns however, 28 75mm, 4 105mm and two 155mm for the coastal defenses, but their ammunition supply was quite limited. The 155mm’s only had 30 shells a piece, while the 105mm had 50. By late July, General Adachi decided to place Major General Shoge Ryoichi in command of the defenses at Lae, talk about a shitty promotion haha. Ryoichi’s rd battalion, 238th regiment was sent first to Salamaua, then Company 6th and the 2nd machine gun company of the 238th regiment managed to reach Lae, but by the time things cooked up the rest would be stuck in Finschhafen. Therefore Rear Admiral Mori Kunizo was sent to grab command of the 7th base force in the meantime while Fujita would lead all the IJN and IJA units currently at Lae. By nightfall on September 3rd, the final voyage began. The allied vessels got to the assembly area unhindered and undetected and by 5:50am on the 4th identified the beach markers. The destroyer transports lowered the landing craft carrying the first wave while performing a 6 minute bombardment. The first landing craft hit the beach at 6:30am and at his guard post at the Japanese anti-aircraft positions overlooking the Lae airfield, private Wada Kiichi heard the sound and saw the flashes of a naval bombardment out in the Guon Gulf. He wrote this ‘Suddenly, there was a booming sound from the sea, and in a split second, I sighted red and yellow tracers come flying on a half moon ballistic arc. Where would the huge fleet land?‘Aren’t they, in fact, landing right here in Lae? ‘If I must die, I will fight with courage and die like an imperial navy man without shame.’ Brigadier Windeyer’s troops began to land at Red and Yellow beach, only meeting 30 members of the 2nd machine gun company of the 238th regiment who they brushed off around the Bulu plantation. General Kenney unleashed air raids against the Japanese airbases. At 7:45am 13 RAAF bombers, 10 Beauforts and 3 A-20 Bostons hit Gasmata; at 9am 24 Liberators hit Lae; at 9:30am 9 Mitchells hit Tuluvu on Cape Gloucester and 3 Bostons returned to hit Gasmata again in the afternoon. As the 22nd squadron War diary noted of the Gasmata raid “the strip is considered unserviceable”. The second wave approached the beach in the larger LCI’s, managing to unload 6 companies without any opposition other than some very annoying reefs near the shore. Thus two waves hit the ground uncontested, but danger did lurk in the skies above. 6 Ki-43 Osca’rs and 3 Ki-51 Sonia’s took off from Lae at 7am and 4 minutes later the Oscars began strafing 7 LCI’s carrying the 2/23rd battalion and its division HQ while the Sonia’s bombed two LCI’s. One of the bombs crashed through the main deck of LCI 339 just forward of its pilot house setting the ship on fire before it began listing to port taking on water. The LCI ran ashore and was abandoned by the crew, 10 of which were wounded. Another bomb narrowly missed LCI 341 exploding near the bottom of the vessel, blowing a large hole amidships on her port side flooding two compartments. The list to port was corrected and the LCI managed to run ashore and would be salvaged later. 9 men were killed with 45 wounded during the attack. 8 Boomerangs and 2 Wirraways came over from Tsili Tsili to aid the next echelons as they began to unload units. The LSTs began clearing the landing area by 11am. The LCT’s took a lot longer to unload than expected, they had arrived at 8am but only cleared the area over the course of 6 hours. Meanwhile, General Imamura frantically launched a strong air raid towards Law consisting of 12 Betty’s, 8 Val’s and 61 Zero’s. The 81 aircraft strong party departed Rabaul, but was soon discovered by destroyer USS Reid lingering off Cape Cretin at around 1pm. Reid’s report gave enough time for the allies to toss a counter air wave to intercept them consisting of 40 Lightnings and 20 Thunderbolts. A few vals tr…
