Vintage, 2002 Autographed Tucker traces her life from her birth as a slave near Independence, Missouri, to her service in Company A, 38th U.S. Infantry, one of the six black units formed following the Civil War. Cathy Williams remains the only known African American woman to have served as a Buffalo Soldier in the Indian Wars. Though over 400 women served in the Civil War posing as male soldiers, Williams was the first African American woman to enlist and the only documented woman to serve in the United States Army, while disguised as a man, during the Indian Wars.
