- 76 - Pacific War - Operation Postern, the drive to Salamaua, May 2-9, 1943

Last time we spoke about actions in New Guinea and the Japanese counteroffensive in Arakan. The good ol boys down unda were getting ready to launch a major offensive aimed to seize Lae and Salamaua. The Australian and American forces gradually built up enough strength to commence the offensive and high command decided to launch some feints, such as at Mubo to distract the Japanese from their real intentions. Over in Arakan, Irwins disaster was still paying dividends to the Japanese as General Koga launched a massive counterattack. Things were continuing to get worse for the British in Burma, though General Slim was beginning to make improvements. Lastly the British began a propaganda campaign to boost morale in the far east using the mad onion man Wingates recent adventure with the Chindits. Things were looking rough in the CBI theater.  This episode is the Operation Postern, the drive to Salamaua Welcome to the Pacific War Podcast Week by Week, I am your dutiful host Craig Watson.

You’ve heard me say it a few times, but because we do this series in the week by week format sometimes we get into these messy weeks where either not much occurs or too much occurs. Regardless this episode is about multiple ongoing operations that culminate into the drive upon Salamaua and for the sake of coherency I am going to have to summarize a lot of what occurred in the south west pacific area for early 1943.  General Blamey devised a plan to capture Lae, codenamed Operation Postern. General MacArthur approved of the plan, which was quite complex and reflected the growing power of the allied forces in the southwest pacific. Blamey moved to New Guinea to take overall charge, reverting Herring to commander of the 1st corps, responsible for tactical operations. The key to quick success lay in convincing General Adachi, that Salamaua was the primary target for any major offensive. To accomplish this, it was necessary for the Australian and American forces to press upon the Japanese around the Salamaua area, but not Salamaua.  Operation Postern was preceded by three simultaneous operations occurring in the South west pacific area and the south pacific area. Together the three operations helped set up the conditions necessary to allow for an amphibious landing at Lae, by tying up the Japanese ground, naval and airpower in the region alongside creating important feints. The invasion of New Georgia was the first of these operations carried out by Admiral Bull Halsey and the 1st raider battalion. That offensive codenamed operation Toenails took up a lot of the Japanese ground, sea and air forces and would gradually see the allies capturing Munda. The 2nd was operation Chronicle, the seizure of Kiriwina and Woodlark islands located just northeast of Milne Bay. With their seizure, the allies were able to create new forward airfields from which to launch air strikes against Rabaul and provide air cover for multiple other operations in the region. Lastly the third operation was to be an assault on Nassau Bay, which we will talk about a bit later. Now back to the ground forces.   The 8th Area Army at Rabaul sent Genera
