- 94 - Pacific War - Operation Postern, September 5-12, 1943

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.

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
