I guess you know she is an affirmative action MOH awardee for political reasons, from 1977.
“After the war, she was approved for the Medal of Honor, for her efforts to treat the wounded in battle and across enemy lines during the Civil War. Notably, the award was not expressly given for gallantry in action at that time, and in fact was the only military decoration during the Civil War. Walker is the only woman to receive the medal and one of only eight civilians to receive it. Her name was deleted from the Army Medal of Honor Roll in 1917 (along with over 900 other recipients); however, it was restored in 1977.”
May be, but doesn’t take away from her actions at the time of her service.
