They worked as nurses and took care of wounded soldiers.
Many nurses in the battlefield were generally nurses who took care of the wounded soldiers in casualty camps.
They enlisted to perform duties such as cooking and cleaning in the army camps.
While there were men who did these (specifically African Americans during the early years of the war), women also did these.
There were other instances of how women helped in the war, some joining the army by cross-dressing, as well as acting as informants and joining spy rings.
