In 1865 Mary Edwards Walker received the Medal of Honor with a note that she could not be given officer's rank because she was a civilian; in 1917 the medal was taken back on that same ground. The episode follows Black physicians and women doctors through the Army's shortages, with doors opening partway and closing again once the need passed.
Sources disagree on who restored Walker's medal, on its award date, and on the number of Black surgeons in the Union Army. Whether Anderson Abbott was ever commissioned is disputed.
