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.
