Battle of Rennell Island
The operation began on 14 January 1943 with the delivery of a battalion of infantry troops to Guadalcanal to act as rearguard for the evacuation. Around the same time, IJA and IJN air forces began an air superiority campaign around the Solomon Islands and New Guinea. During the air campaign, a US cruiser was sunk in the Battle of Rennell Island. Two days later, Japanese aircraft sank a US destroyer near Guadalcanal. The withdrawal was carried out on the nights of 1, 4, and 7 February by destroyers.
