Robert P. Patterson became Secretary of War on 27 September 1945, after serving with Henry Stimson for five years, first as assistant and later as under secretary. Intimately concerned with racial matters in the early years of the war, Patterson later became involved in war procurement, a specialty far removed from the complex and controversial racial situation that faced the Army. Now as secretary he once again assumed an active role in the Army's black manpower problems and quickly responded to McCloy's request for a policy review.[6-2] In accordance with Patterson's oral instructions, General Marshall appointed a board, under the chairmanship of Lt. Gen. Alvan C. Gillem, Jr., which met on 1 October 1945. Three days later a formal directive signed by the Deputy Chief of Staff and approved by the Secretary of War ordered the board to "prepare a policy for the use of the authorized Negro manpower potential during the postwar period including the complete development of the means required to derive the maximum efficiency from the full authorized manpower of the nation in the event of a national emergency."[6-3] On this group, to be known as the Gillem Board, would fall the responsibility for formulating a policy, preparing a directive, and planning the use of Negroes in the postwar Army.
