Just to keep witt company:
The Battle of Saipan was a battle of the Pacific campaign of World War II, fought on the island of Saipan in the Mariana Islands from 15 June–9 July 1944. The Allied invasion fleet embarking the expeditionary forces left Pearl Harbor on 5 June 1944, the day before Operation Overlord in Europe was launched. The U.S. 2nd Marine Division, 4th Marine Division, and the Army’s 27th Infantry Division, commanded by Lieutenant General Holland Smith, defeated the 43rd Division of the Imperial Japanese Army, commanded by Lieutenant General Yoshitsugu Saito….
… The victory would prove to be one of the most important strategic moments during the war in the Pacific Theater, as the Japanese mainland was now within striking distance of United States’ B-29 bombers.
