With the death of Lieutenant-General Buckner on 18 June 1945, Roy S Geiger assumed command of Tenth Army, the only Marine officer to command a field army, while retaining command of IIIAC. The next day he was promoted to Lieutenant-General. General Buckner had expressly picked Geiger to assume command in the event of his death. Five days later, Geiger was relieved by Lieutenant-General Joseph W. Stilwell.
