During the Battle of Saipan, the 2nd Marine Division's scout company performed a series of special missions with 4th Marine Division's scout company, which included a recon detachment with 1st Battalion, 9th Marine Regiment (1/9). Seizing the summit of Mount Tapochau, the highest point on the island, they later repulsed a Japanese counterattack. Both Admiral Richmond K. Turner and General Holland M. Smith declared Saipan secured on July 9, 1944.
