Black soldiers were often the victims of gross discrimination that transcended their difficulties with the Army's administration. For instance, black soldiers, particularly those from more integrated regions of the country, resented local ordinances governing transportation and recreation facilities that put them at a great disadvantage in the important matters of leave and amusement. Infractions of local rules were inevitable and led to heightened racial tension and recurring violence.[2-54] At times black soldiers themselves, reflecting the low morale and lack of discipline in their units, instigated the violence. Whoever the culprits, the Army's files are replete with cases of discrimination charged, investigations launched, and exonerations issued or reforms ordered.[2-55] An incredible amount of time and effort went into handling these cases during the darkest days of the war--cases growing out of a policy (p. 039) created in the name of military efficiency.

For an extended discussion of this subject, see Lee, _Employment of Negro Troops_, ch XI-XIII.] Nor was the violence limited to the United States. Racial friction also developed in Great Britain where some American troops, resenting their black countrymen's social acceptance by the British, tried to export Jim Crow by forcing the segregation of recreational facilities. Appreciating the treatment they were receiving from the British, the black soldiers fought back, and the clashes grew at times to riot proportions. General Davis considered discrimination and prejudice the cause of trouble, but he placed the immediate blame on local commanders. Many commanders, convinced that they had little jurisdiction over racial disputes in the civilian community or simply refusing to accept responsibility, delegated the task of keeping order to their noncommissioned officers and military police.[2-56] These men, rarely experienced in handling racial disturbances and often prejudiced against black soldiers, usually managed to exacerbate the situation.
