Promoted to colonel in 1937, Buckner commanded the 66th Infantry Regiment in 1937 and 1938. He was then on duty with the Civilian Conservation Corps in Alabama between 1938 and 1939, before serving as chief of staff of the 6th Infantry Division in 1939 and 1940. Buckner was promoted to brigadier general to October 1940 and to major general in August 1941. Between 1940 and 1944, he headed the Alaska Defense Command. His primary responsibility was the construction of defense facilities, but units of his command cooperated with the navy in evicting the Japanese from two of the Aleutian Islands, Attu and Kiska.
A month after being promoted to lieutenant general in May 1943, Buckner went to Hawaii to organize the new Tenth Army. He headed an army review panel that investigated the intraservice dispute over Marine Lieutenant General Holland M. Smith's relief of Army Major General Ralph Smith on Saipan. Buckner commanded the main landings on Okinawa in April 1945. Citing logistical difficulties, he rejected navy pleas that he mount a subsidiary landing on the south end of the island.
On 18 June 1945, just three days before organized Japanese resistance ended, Buckner was killed by a coral fragment sent flying by the explosion of a Japanese shell. He was the highest-ranking American officer killed by enemy fire during the war. Richard G. Stone
