On June 15, 1944, during the Pacific Campaign of World War II (1939-45), U.S. Marines stormed the beaches of the strategically significant Japanese island of Saipan, with a goal of gaining a crucial air base from which the U.S. could launch its new long-range B-29 bombers directly at Japan’s home islands. Facing fierce Japanese resistance, Americans poured from their landing crafts to establish a beachhead, battle Japanese soldiers inland and force the Japanese army to retreat north. When the U.S. finally trapped the Japanese in the northern part of the island, Japanese soldiers launched a massive but futile banzai charge. On July 9, the U.S. flag was raised in victory over Saipan. [History.com]
