By 15 June the 1st Marines had been in the division line for 12 straight days and sustained 500 casualties. The 5th Marines relieved it, including an intricate night-time relief of lines by 2/5 of 2/1 on 15–16 June. The 1st Marines, back in the relative safety of division reserve, received this mindless regimental rejoinder the next day: “When not otherwise occupied you will bury Jap dead in your area.”

The battle for Kunishi Ridge continued. On 17 June the 5th Marines assigned K/3/5 to support 2/5 on Kunishi. Private First Class Sledge approached the embattled escarpment with dread: “Its crest looked so much like Bloody Nose that my knees nearly buckled. I felt as though I were on Peleliu and had it all to go through again.” The fighting along the crest and its reverse slope took place at point-blank range—too close even for Sledge’s 60mm mortars. His crew then served as stretcher bearers, extremely hazardous duty. Half his company became casualties in the next 22 hours.

Extracting wounded Marines from Kunishi remained a hair-raising feat. But the seriously wounded faced another half-day of evacuation by field ambulance over bad roads subject to interdictive fire. Then the aviators stepped in with a bright idea. Engineers cleared a rough landing strip suitable for the ubiquitous “Grasshopper” observation aircraft north of Itoman. Hospital corpsmen began delivering some of the casualties from the Kunishi and Hill 69 battles to this improbable airfield. There they were tenderly inserted into the waiting Piper Cubs and flown back to field hospitals in the rear, an eight-minute flight. This was the dawn of tactical air medevacs which would save so many lives in subsequent Asian wars. In 11 days, the dauntless pilots of Marine Observation Squadrons (VMO) -3 and -7 flew out 641 casualties from the Itoman strip.

The 6th Marine Division joined the southern battlefield from its forcible seizure of the Oroku Peninsula. Colonel Roberts’ 22d Marines became the fourth USMC regiment to engage in the fighting for Kunishi. The 32d Infantry Regiment died hard, but soon the combined forces of IIIAC had swept south, overlapped Mezado Ridge, and could smell the sea along the south coast. Near Ara Saki, George Company, 2/22, raised the 6th Marine Division colors on the island’s southernmost point, just as they had done in April at Hedo Misaki in the farthest north.

The long-neglected 2d Marine Division finally got a meaningful role for at least one of its major components in the closing weeks of the campaign. Colonel Clarence R. Wallace and his 8th Marines arrived from Saipan, initially to capture two outlying islands, Iheya Shima and Aguni Shima, to provide more early warning radar sites against the kamikazes. Wallace in fact commanded a sizable force, virtually a brigade, including the attached 2d Battalion, 10th Marines (Lieutenant Colonel Richard G. Weede) and the 2d Amphibian Tractor Battalion (Major Fenlon A. Durand). General Geiger assigned the 8th Marines to the 1st Marine Division, and by 18 June they had relieved the 7th Marines and were sweeping southeastward with vigor. Private First Class Sledge recalled their appearance on the battlefield: “We scrutinized the men of the 8th Marines with that hard professional stare of old salts sizing up another outfit. Everything we saw brought forth remarks of approval.”

General Buckner also took an interest in observing the first combat deployment of the 8th Marines. Months earlier he had been favorably impressed with Colonel Wallace’s outfit during an inspection visit to Saipan. Buckner went to a forward observation post on 18 June, watching the 8th Marines advance along the valley floor. Japanese gunners on the opposite ridge saw the official party and opened up. Shells struck the nearby coral outcrop, driving a lethal splinter into the general’s chest. He died in 10 minutes, one of the few senior U.S. officers to be killed in action throughout World War II.

As previously arranged, General Roy Geiger assumed command; his third star became effective immediately. The Tenth Army remained in capable hands. Geiger became the only Marine—and the only aviator of any service—to command a field army. The soldiers on Okinawa had no qualms about this. Senior Army echelons elsewhere did. Army General Joseph Stillwell received urgent orders to Okinawa. Five days later he relieved Geiger, but by then the battle was over.
