The Marines on Iwo Island continued to drive forward on the afternoon of March 10. By 1800 the 4th Division had made substantial advances along most of its front and one of its patrols had reached the beach on the easternmost point of the island. Enemy resistance appeared to be decreasing at numerous points along the lines. Army and Navy aircraft continued to attack enemy positions and fleet surface units provided close gunfire support.
Corsair fighters of the 4th Marine Aircraft Wing bombed and strafed docks, small craft, and defense positions on Ponape in the eastern Carolines on March 10.
