Battle of the Bismarck Sea
The ultimate goal of the Allied counter-offensives in New Guinea and the Solomon's was to capture the main Japanese base at Rabaul on New Britain.
Also, to clear the way for the eventual reconquest of the Philippines.
Recognising the threat, the Japanese continued to send land, naval, and aerial reinforcements to the area in an attempt to check the Allied advances.
The Battle of the Bismarck Sea (2–4 March 1943) took place in the South West Pacific Area (SWPA) during World War II when aircraft of the United States Army 5th Air Force and the Royal Australian Air Force attacked a Japanese convoy carrying troops to Lae, New Guinea.
Most of the Japanese task force was destroyed and Japanese troop losses were heavy.
