Gen Vandegrift, 1st Marine Division commander on Guadalcanal, relieved MajGen Clayton B. Vogel as IMAC commander in July 1943. He in turn was relieved as IMAC commander by MajGen Charles D. Barrett on 27 September. Gen Vandegrift was on his way home to Washington to become 18th Commandant of the Marine Corps when, on the sudden death of Gen Barrett on 8 October, he was recalled to the Pacific to resume command of IMAC and lead it in the Bougainville operation. He, in turn, was relieved by MajGen Roy S. Geiger on 9 November.
