The Bureau of Naval Personnel concluded that, since many units were substantially or wholly manned by Negroes, black officers could be used without undue difficulty, and when Secretary Knox, prodded by Stevenson, turned to the bureau, it recommended that the Navy (p. 082) commission twelve line and ten staff officers from a selected list of enlisted men.[3-76] Admiral King endorsed the bureau's recommendation and on 15 December 1943 Knox approved it, although he conditioned his approval by saying: "After you have commissioned the twenty-two officers you suggest, I think this matter should again be reviewed before any additional colored officers are commissioned."[3-77] [Footnote 3-76: Memo, SecNav for Chief, NavPers, 20 Nov 43, 54-1-50; Memo, Chief, NavPers, for SecNav, 2 Dec 43, sub: Negro Officers. Both in GenRecsNav.] [Footnote 3-77: Memo, SecNav for Rear Adm Jacobs, 15 Dec 43, quoted in "BuPers Hist," p. 33.] On 1 January 1944 the first sixteen black officer candidates, selected from among qualified enlisted applicants, entered Great Lakes for segregated training. All sixteen survived the course, but only twelve were commissioned. In the last week of the course, three candidates were returned to the ranks, not because they had failed but because the Bureau of Naval Personnel had suddenly decided to limit the number of black officers in this first group to twelve. The twelve entered the U.S. Naval Reserve as line officers on 17 March. A thirteenth man, the only candidate who lacked a college degree, was made a warrant officer because of his outstanding work in the course. Two of the twelve new ensigns were assigned to the faculty at Hampton training school, four others to yard and harbor craft duty, and the rest to training duty at Great Lakes. All carried the label "Deck Officers Limited--only," a designation usually reserved for officers whose physical or educational deficiencies kept them from performing all the duties of a line officer. The Bureau of Naval Personnel never explained why the men were placed in this category, but it was clear that none of them lacked the physical requirements of a line officer and all had had business or professional careers in civil life. Operating duplicate training facilities for officer candidates was costly, and the bureau decided shortly after the first group of black candidates was trained that future candidates of both races would be trained together. By early summer ten more Negroes, this time civilians with special professional qualifications, had been trained with whites and were commissioned as staff officers in the Medical, Dental, Chaplain, Civil Engineer, and Supply Corps. These twenty-two men were the first of some sixty Negroes to be commissioned during the war.
