Across The Reef: The Marine Assault of Tarawa

In August 1943, to meet in secret with Major General Julian C. Smith and his principal staff officers of the 2d Marine Division, Vice Admiral Raymond A. Spruance, commanding the Central Pacific Force, flew to New Zealand from Pearl Harbor. Spruance told the Marines to prepare for an amphibious assault against Japanese positions in the Gilbert Islands in November.

The Marines knew about the Gilberts. The 2d Raider Battalion under Lieutenant Colonel Evans F. Carlson had attacked Makin Atoll a year earlier. Subsequent intelligence reports warned that the Japanese had fortified Betio Island in Tarawa Atoll, where elite forces guarded a new bomber strip. Spruance said Betio would be the prime target for the 2d Marine Division.
