As the improved military bearing and efficiency of black trainees and the subsequent impressive performance of the two new infantry battalions would suggest, the reports on the Grafenwohr training were optimistic and the lessons drawn ambitious. They prompted Huebner on 1 December 1947 to establish a permanent training center at Kitzingen Air Base.[8-26] Essentially, he was trying to combine both drill and constant supervision with a broad-based educational program. Trainees received basic military training for six hours daily and academic instruction up to the twelfth grade level for two hours more. The command ordered all black replacements and casuals arriving from the United States to the training center for classifying and training as required. Eventually all black units in Europe were to be rotated through Kitzingen for unit refresher and individual instruction. As each company completed the course at Kitzingen, the command assigned academic instructors to continue an on-duty educational program in the field. A soldier was required to participate in the educational program until he passed the general education development test for high school level or until he clearly demonstrated that he could not profit from further instruction. [Footnote 8-26: The training center had already moved from Grafenwohr to larger quarters at Mannheim Koafestal, Germany.] Washington was quick to perceive the merit of the European program, and Paul reported widespread approval "from all concerned."[8-27] The program quickly produced some impressive statistics. Thousands of (p. 218) soldiers--at the peak in 1950 more than 62 percent of all Negroes in the command--were enrolled in the military training course at Kitzingen or in on-duty educational programs organized in over two-thirds of the black companies throughout the command. By June 1950 the program had over 2,900 students and 200 instructors. A year later, the European commander estimated that since the program began some 1,169 Negroes had completed fifth grade in his schools, 2,150 had finished grade school, and 418 had passed the high school equivalency test.[8-28] The experiment had a practical and long-lasting effect on the Army. For example, in 1950 a sampling of three black units showed that after undergoing training at Kitzingen and in their own units the men scored an average of twenty points higher in Army classification tests. According to a 1950 European Command estimate, the command's education program was producing some of the finest trained black troops in the Army.

Walter White, however, supported the program. See Interv, author with Huebner.]
