In the Guadalcanal Campaign of the Second World War, the Allies reversed the gains of Imperial Japan in the southwest Pacific. U.S. forces had inflicted heavy losses on the Imperial Japanese Navy at the Battle of Midway in June 1942, but Japan had remained on the offensive, pushing into the Solomon Islands from Rabaul and threatening supply lines to Australia and New Zealand. In August 1942, U.S. Marines landed on Guadalcanal in the southern Solomon Islands. The Japanese had occupied the islands since May, and were building an airfield (later named Henderson Field). The Allies overwhelmed the surprised Japanese defenders and captured the airfield. The Japanese attempted to retake it but were defeated in the Naval Battle of Guadalcanal in early November. They abandoned their campaign in December, and evacuated their remaining forces on 7 February 1943. The Allied victories on Guadalcanal, and in New Guinea, marked the transition from defensive operations to a series of offensives that culminated in the Japanese surrender in 1945. (Full article...)
