The Raid on Makin Island (17–18 August 1942) was an attack by the United States Marine Corps Raiders on Japanese military forces on Makin Island (now known as Butaritari) in the Pacific Ocean. The aim was to destroy Imperial Japanese installations, take prisoners, gain intelligence on the Gilbert Islands area, and divert Japanese attention and reinforcements from the Allied landings on Guadalcanal and Tulagi. Only the first of these objectives was achieved, but the raid did boost morale and provide a test for Raider tactics.
