When the fighting units reached France and were receiving final training before moving up to the front line trenches, many of the officers attended various schools. The majority of such men completed the courses with high standing. One of the schools that proved a distinct success was a machine-gun school conducted by colored officers in charge of Lieut. B. A. Mosley, who made out the courses of study. The object was to make machine-gun officers out of infantry officers, giving them the principles of machine gunnery. Nearly two hundred officers and non-commissioned officers were sent from this school, which was approved by the First Corps and put on the standard of the A. E. F. schools. Under date August 27, 1918, Major John P. Bubb said of one of these schools: “In submitting reports of proficiency of captains of the 92nd Division who have recently been under my instruction, I request attention to the following facts. Certain captains, namely, Jones, Saunders, Scott, Stephens, Holland, Hollingsworth, and Granson, have done very well in their work. They are serious, dignified men of excellent caliber and are fully able to maintain the positions of trust and confidence in which they have been placed.... The balance of the class (all captains) are I believe as good as the average student who has passed through the school.” In the fourth officers’ school, opened on May 15, 1918, at Camp Dodge, there were 280 Negro candidates, which number was soon increased to more than 300. These candidates were selected principally from the units of the 92nd Division, though some came from elsewhere. This school began under the command of Lt. Col. William G. Doane, who was assisted by ten colored men, with Captain M. T. Dean as senior instructor. For the first time in America, Negro officers in large numbers were instructing soldiers in the science of modern warfare, preparing them directly to take their places as officers in the great National Army. These men served for fifteen days, when a telegram was sent from the headquarters of the 92nd calling all the officers to their regiment. Their work, however, had proved a success. The candidates were all picked men, the school was well organized, and the officers showed the greatest confidence and faith in each other.
