Final answer:
Henry Johnson and Neeham Roberts were awarded the Croix de Guerre by the French for their heroism in World War I, and Johnson received the Medal of Honor posthumously from the U.S.
Step-by-step explanation:
Henry Johnson and Neeham Roberts, members of the 369th Infantry Regiment, also known as the Harlem Hellfighters, were awarded the Croix de Guerre by the French government for their valor during World War I. Serving under French command, these African American soldiers experienced no segregation and fought in significant battles like the second battle of the Marne and the Meuse-Argonne offensive. Johnson's act of heroism alongside Roberts, defending against a German raid with just rifles and a bolo knife, was later recognized with the highest U.S. military decoration, the Medal of Honor, awarded posthumously.
