Before anyone gets started on claiming there were no black US combat troops during WW-1,the unit this man was with was attached to the French Army. The French were desperate for replacements for all the French troops that were killed or crippled due to the insanity of trench warfare,and were greateful to have the black Americans,and by all reports treated them well.
That man's family needs to check on why he never received any awards from the French. Chances are he was supposed to,and the paperwork got lost.
