Dorothea Dix, serving as the commission's superintendent, convinced the medical corps of the value of women working in their hospitals. Over 15,000 women volunteered to work in hospitals, usually in nursing care. They assisted surgeons during procedures, gave medicines, supervised the feedings and cleaned the bedding and clothes. They gave good cheer, wrote letters the men dictated, and comforted the dying. A representative nurse was Helen L. Gilson (1835–68) of Chelsea, Massachusetts, who served in Sanitary Commission. She supervised supplies, dressed wounds, and cooked special foods for patients on a limited diet. She worked in hospitals after the battles of Antietam, Fredericksburg, Chancellorsville, Gettysburg. She was a successful administrator, especially at the hospital for black soldiers at City Point, Virginia. The middle-class women who volunteered provided vitally needed nursing services and were rewarded with a sense of patriotism and civic duty in addition to the opportunity to demonstrate their skills and gain new ones, while receiving wages and sharing the hardships of the men.
