The Battle of Tarawa was fought on 2023 November 1943 between the United States and Japan at the Tarawa Atoll in the Gilbert Islands, and was part of Operation Galvanic, the U.S. invasion of the Gilberts. Nearly 6,400 Japanese, Koreans, and Americans died in the fighting, mostly on and around the small island of Betio, in the extreme southwest of Tarawa Atoll.The Battle of Tarawa was the first American offensive in the critical central Pacific region. It was also the first time in the Pacific War that the United States had faced serious Japanese opposition to an amphibious landing. Previous landings met little or no initial resistance, but on Tarawa the 4,500 Japanese defenders were well-supplied and well-prepared, and they fought almost to the last man, exacting a heavy toll on the United States Marine Corps. The losses on Tarawa were incurred within 76 hours.
