During WWI, in the very racially segregated American Expeditionary Force (AEF), there were many instances behind the lines on the Western Front of racial attacks on African-American soldiers by bigoted whites- including summary executions at the hands of white MPs- and even 1 or 2 cases of French African colonial troops being murdered by racist white Americans. Of course, with the massive racial climate prevalent in America at that time, such racial violence was inevitable- but WI the full force oif such racial problems in the US had transferred across the Atlantic and exploded in the same way among blacks and whites behind the front lines, similar to the race riots which occurred at East St Louis and other places, or the Houston Mutiny, during 1917 ? WI also there'd been more widespread racial attacks by white American troops on French African colonials to the extent of the latter- perhaps abetted by btheir own white officers- actually actively participating in largescale retaliatory assaults on the former ? Could there have actually been race riots in French behind-the-front towns along similar lines as what happened at East St Louis and Houston, and could such disturbances have been serious enough to affect the deployment of the AEF on the battlefield against the Germans ?
