The Battle of Kwajalein was a military engagement fought between US forces, under Rear Admiral Richmond K Turner, and the Japanese garrison, composed of 7,000 men, commanded by Monzo Akiyama, from February 1 to February 3, 1944, in the Pacific theater of operations, during the Second World War. Kwajalein is an atoll in the Marshall Islands composed of several islets, of which Kwajalein proper, located on the south, and Roi-Namur, on the north, are the biggest ones. The landing on these islands was part of the Pacific Campaign to end the Japanese imperial domination and took place more than two months after the landing at Tarawa (November 20-23, 1943).
To soften up the terrain, both Kwajalein and Roi-Namur islands were subjected to intense bombing carried out by American battleships and B-24 bombers. Having taken smaller islets lying on the periphery on January 31, the US Army 7th Infantry Division, led by Major General Charles H Corlett, landed on Kwajalein on the morning of February 1, while the 4th Marine Division proceded to land on Roi-Namur the same day. After fierce fighting, these American units managed to bring both islands under control by February 3. On Kwajalein, more than 3,000 Japanese soldiers were killed in action, while on Roi-Namur and other islets more than 3,200, with their commander Admiral Monzo Akiyama among them.
