"No comprehensive studies have as yet been devoted to the role of Africans in the armies of the colonial powers in a variety of contexts. However, the indications are that such studies would reveal a pattern very similar to that discovered by historians who have looked at the role of black soldiers in the white-controlled armies of the U.S.A.; namely, that there was tremendous discrimination against black fighting men, even though black soldiers made great and unacknowledged contributions to important victories won by the white-officered armies of the U.S.A. and the colonial powers. Hints regarding discrimination are to be seen from regulations such as that barring African soldiers in the West African Regiment from wearing shoes and from the fact that there were actually race riots in the European campaigns, just as black troops fighting for the U.S.A. continued to riot right up to the Vietnam campaign."
