Expended shells and open ammunition boxes testify to the heavy supporting fire this water-cooled, .30-caliber Browning machine gun poured on the enemy as Marines advanced in the furious and difficult battle for the heights of Suribachi.
The next day, D+6, 25 February, provided little relief in terms of Japanese resistance. Small groups of Marines, accompanied by tanks, somehow made it across the runway, each man harboring the inescapable feeling he was alone in the middle of a gigantic bowling alley. Sometimes holding newly gained positions across the runway proved more deadly than the process of getting there. Resupply became nearly impossible. Tanks were invaluable; many were lost.
Schmidt this day managed to get on shore the rest of his corps artillery, two battalions of 155mm howitzers under Colonel John S. Letcher. Well-directed fire from these heavier field pieces eased some of the pressure. So did call fire from the cruisers and destroyers assigned to each maneuver unit. But the Marines expressed disappointment in their air support. The 3d Marine Division complained that the Navy’s assignment of eight fighters and eight bombers on station was “entirely inadequate.” By noon on this date General Cates sent a message to Schmidt requesting that “the Strategic Air Force in the Marianas replace Navy air support immediately.” Colonel Vernon E. Megee, now ashore as Air Commander Iwo Jima and taking some of the heat from frustrated division commanders, blamed “those little spit-kit Navy fighters up there, trying to help, never enough, never where they should be.”
In fairness, it is doubtful whether any service could have provided effective air support during the opening days of the drive north. The Air Liaison Parties with each regiment played hell trying to identify and mark targets, the Japanese maintained masterful camouflage, frontline units were often “eyeball-to-eyeball” with the enemy, and the air support request net was overloaded. The Navy squadrons rising from the decks of escort carriers improved thereafter, to the extent that their conflicting missions would permit. Subsequent strikes featured heavier bombs (up to five hundred pounds) and improved response time. A week later General Cates rated his air support “entirely satisfactory.” The battle of Iwo Jima, however, would continue to frustrate all providers of supporting arms; the Japanese almost never assembled legitimate targets in the open.
“The Japs weren’t on Iwo Jima,” said Captain Fields of the 26th Marines, “they were in Iwo Jima.”
Richard Wheeler, who survived service with the 28th Marines and later wrote two engrossing books about the battle, pointed out this phenomenon:
This was surely one of the strangest battlefields in history, with one side fighting wholly above the ground and the other operating almost wholly within it. Throughout the battle, American aerial observers marveled at the fact that one side of the field held thousands of figures, either milling around or in foxholes, while the other side seemed deserted. The strangest thing of all was that the two contestants sometimes made troop movements simultaneously in the same territory, one maneuvering on the surface and the other using tunnels beneath.
As the Marines struggled to wrest the second airfield from the Japanese, the commanding terrain features rising to the north caught their attention. Some would become known by their elevations (although there were three Hill 362s on the island), but others would take the personality and nicknames assigned by the attackers. Hence, the 4th Marine Division would spend itself attacking Hill 382, the “Amphitheater,” and “Turkey Knob” (the whole bristling complex became known as “The Meatgrinder”). The 5th Division would earn its spurs and lose most of its invaluable cadre of veteran leaders attacking Nishi Ridge and Hills 362-A and 362-B, then end the fighting in “The Gorge.” The 3d Division would focus first on Hills Peter and 199-Oboe, just north of the second airfield, then the heavily fortified Hill 362-C beyond the third airstrip, and finally the moonscape jungle of stone which would become known as “Cushman’s Pocket.”
Lieutenant Colonel Robert E. Cushman, Jr., a future Commandant, commanded the 2d Battalion, 9th Marines at Iwo Jima. Cushman and his men were veterans of heavy fighting in Guam, yet they were appalled by their first sight of the battlefield. Wrecked and burning Sherman tanks dotted the airstrips, a stream of casualties flowed to the rear, “the machine-gun fire was terrific.” Cushman mounted his troops on the surviving tanks and roared across the field. There they met the same reverse-slope defenses which had plagued the 21st Marines. Securing the adjoining two small hills—Peter and 199-Oboe—took the 3d Marine Division three more days of intensely bitter fighting.
General Schmidt, considering the 3d Division attack in the center to be his main effort, provided priority fire support from Corps artillery, and directed the other two divisions to allocate half their own regimental fire support to the center. None of the commanders was happy with this. Neither the 4th Division, taking heavy casualties in The Amphitheater as it approached Hill 382, nor the 5th Division, struggling to seize Nishi Ridge, wanted to dilute their organic fire support. Nor was General Erskine pleased with the results. The main effort, he argued, should clearly receive the main fire. Schmidt never did solve this problem. His Corps artillery was too light; he needed twice as many battalions and bigger guns—up to 8-inch howitzers, which the Marine Corps had not yet fielded. He had plenty of naval gunfire support available and used it abundantly, but unless the targets lay in ravines facing to the sea he lost the advantage of direct, observed fire.
