World War II: Japan successfully withdrew its troops from Guadalcanal.

World War II or the Second World War was a global conflict between two coalitions: the Allies and the Axis powers. Nearly all of the world's countries participated, with many nations mobilising all resources in pursuit of total war. Tanks and aircraft played major roles, enabling the strategic bombing of cities and delivery of the first and only nuclear weapons ever used in war. World War II is the deadliest conflict in history, causing the death of 70 to 85 million people, more than half of whom were civilians. Millions died in genocides, including the Holocaust, and by massacres, starvation, and disease. After the Allied victory, Germany, Austria, Japan, and Korea were occupied, and German and Japanese leaders were tried for war crimes.

Operation Ke was the largely successful withdrawal of Japanese forces from Guadalcanal, concluding the Guadalcanal Campaign of World War II. The operation took place between 14 January and 7 February 1943, and involved both Imperial Japanese Army (IJA) and Imperial Japanese Navy (IJN) forces under the overall direction of the Japanese Imperial General Headquarters (IGH). Commanders of the operation included Isoroku Yamamoto and Hitoshi Imamura.

Guadalcanal is the principal island in Guadalcanal Province of Solomon Islands, located in the southwestern Pacific Ocean, northeast of Australia. It is the largest island in the Solomons by area and the second-largest by population. The island is mainly covered in dense tropical rainforest and has a mountainous hinterland.
