Maj. Gen. Harry Schmidt, commander of the Marine landing force, requested a 10-day heavy shelling of the island immediately preceding the mid-February amphibious assault. However, Rear Adm. William H.P. Blandy, commander of the Amphibious Support Force (Task Force 52), did not believe such a bombardment would allow him time to replenish his ships’ ammunition before the landings; he thus refused Schmidt’s request. Schmidt then asked for nine days of shelling; Blandy again refused and agreed to a three-day bombardment. This decision left much hard feeling among the Marines. After the war, Lieut. Gen. Holland M. “Howlin’ Mad” Smith, commander Expeditionary Troops (Task Force 56, which consisted of Schmidt’s Fifth Amphibious Corps), bitterly complained that the lack of naval gunfire had cost Marine lives during the entire Allied island campaign.
The limited bombardment had questionable success on the enemy due to the Japanese being heavily dug-in and fortified. However, many bunkers and caves were destroyed during the bombing giving it some limited success. The Japanese had been preparing for this battle since March 1944, which gave them a significant head start. By the time of the landing, about 450 American ships were located off Iwo Jima. The entire battle involved about 60,000 U.S. Marines and several thousand U.S. Navy Seabees.
