That would have been during the wind up of the Buna-Gona battles.In the summer of '42, after the Coral Sea Battle put a stop to the japs attemptto take Port Moresby by sea, they attempted to take it by land across the Owen Stanely Mts.They came across the Kokoda Trail and got within 30 miles of Moresby.The Aussie 7th and 9th Divs. and the U.S. 32 Div. stopped them and drove them back. The 41st Div. entered the fray, I belive, in the fall of '42.It all ended in the Buno-Gona Sanananda Point battles. That campaign was supplied entirely by air.The 3rd Bomb. Gp. gave air support to the ground troops thru out the campaign. In late Feb. '43 the japs tried to bring a convoy down from Rabaul on New Britain to reinforce Lae with 6000 ground troops.That resulted in the Bismark Sea Battle the first couple days of March.That was strictly an Airforce operation, the 3rd playing a major part with their recently converted B-25 and A-20 low level straffer skip bombers.The convoy was destroyed, 6000 troops dumped in the drink.For all practical purposes that ended the jap advance in the S.W. Pacific and started our two year trek back to the P.I.
