Book excerpt: A pictorial history of US assaults on these Japanese-occupied islands during World War II. This book in the Images of War series covers the dramatic events that befell both the Gilbert and Ellice Pacific island groups using a wealth of photos and informed text. Soon after the attack on Pearl Harbor in December 1941, the Gilbert Islands were occupied by the Japanese, who built a seaplane base at Butaritari. In August 1942 this base was attacked by the US 2nd Raider Battalion, also known as Carlson’s Raiders. As a result the base was reinforced and a second built at Apamama. Betio Island on the Tarawa Atoll became the main Japanese strong point. Operation Galvanic, the US assault on Butaritari, Apamama, and Betio, was launched in November 1943 by the 2nd Marine Division and the 27th Infantry Division. While short in duration, the Betio battle has the dubious distinction of being the most costly in US Marine Corps history. Enriched by the author’s in-depth knowledge and access to superb contemporary images, this book is ideal for both historians and anyone interested in the Pacific War. “An excellent overview of the battle for the Gilberts.” —Air Power History
