Who were the Harlem Hellfighters and what was their impact?​

The 369th Infantry Regiment, "Harlem Hellfighters," were a unit made of African Americans (to be PC) and were well known for their ferociousness in battle. They fought in both WW1 and WW2, and they spent the most time in combat in WW1 than any other unit (remember, America joined the war in 1917!)

Their effect on the war effort couldn't be understated, that even the Germans acknowledged them, referring to them as "Höllenkämpfer" (German for Hell Fighters) and earned the nickname "Men of Bronze" by the French (Hommes de Bronze).
