The Harlem Hell Fighters
One group of men who served on the front lines was the 369th infantry of the 93rd division, a group of African American soldiers better known as the Harlem Hellfighters and Men of Bronze, nicknames given to them by the French. These men were known for their fierce combat, fighting longer and harder than any other infantry. The tenacity and toughness of the Harlem Hellfighters continue with us today as we remember and honor their lives and the lives of all who valiantly served in the military.
