Milne Bay is a large bay inMilne Bay Province, south-easternmostPapua New Guinea. More than 35 km (22 mi) long and over 15 km (9 mi) wide, Milne Bay is a sheltered deep-water harbor accessible viaWard Hunt Strait. It is surrounded by the heavily woodedStirling Range to the north and south, and on the northern shore, a narrow coastal strip, soggy withsago andmangrove swamps.[1] The bay is named afterSir Alexander Milne.

DuringWorld War II, the area was the site of theBattle of Milne Bay in 1942 and by late 1943 it became the major support base,Naval Base Milne Bay, for theNew Guinea campaign through the development ofFinschhafen as an advanced base after that area was secured in theHuon Peninsula campaign. By January 1944 about 140 vessels were in harbor due to congestion at the facilities.
Congestion was relieved by opening of a port at Finschhafen and extensive improvements at Milne Bay.[5] Malaria was a major problem in New Guinea and Milne Bay was particularly hard hit with incidents of the disease hitting at a rate of 4,000 cases per 1,000 troops per year and estimated 12,000 man-days a month lost time.[6]
There were three planes ditched off the island in 1943, aP-38H Lightning, a P-38F Lightning, and aB-24D Liberator "The Leila Belle" (MIA).[7]
