In March 1943 Allied reconnaissance aircraft spot a Japanese convoy carrying troops and supplies to Lae. These will reinforce Japanese forces fighting a gruelling battle against American and Australian forces in the jungles of New Guinea. Over two days, coordinated Allied air attacks devastate the force, sinking all eight transports and four destroyers. Thousands of Japanese troops are lost, and the defeat cripples Japans ability to reinforce its positions in New Guinea. The battle showcases the growing dominance of Allied air power, the effectiveness of new attack tactics, and mark a critical step in the Allied drive toward victory in the Southwest Pacific campaign.
