On September 4, 1945, the Japanese garrison surrendered to a detachment of United States Marines under the command of Brigadier General Lawson H. M. Sanderson. The garrison, having previously received news that Imperial Japan's defeat was imminent, exhumed the mass grave. The bones were moved to the U.S. cemetery that had been established on Peacock Point after the invasion. Wooden crosses were erected in preparation for the expected arrival of U.S. forces. During the initial interrogations, the Japanese claimed that the remaining 98 Americans on the island were mostly killed by an American bombing raid, though some escaped and fought to the death after being cornered on the beach at the north end of Wake Island. Several Japanese officers in American custody committed suicide over the incident, leaving written statements that incriminated Sakaibara. Sakaibara and his subordinate, lieutenant commander Tachibana, were later sentenced to death after conviction for this and other war crimes. Sakaibara was executed by hanging in Guam on June 18, 1947, while Tachibana's sentence was commuted to life in prison. The remains of the murdered civilians were exhumed and reburied at Honolulu's National Memorial Cemetery of the Pacific at section G, commonly known as Punchbowl Crater.
