Dr. Mary Walker gave her services on the field as surgeon, winning an acknowledged reputation in the Second corps, army of the Potomac, for professional superiority. She applied for a commission as assistant surgeon, but was refused by Surgeon-General Hammond because of her sex. Dr. Walker suffered imprisonment in Castle Thunder, Richmond, having been taken prisoner. The special correspondent of the _N. Y. Tribune_, Headquarters Army of the Potomac, Sept. 15, 1863, said: "She applied to both Surgeon-Generals Finlay and Hammond for a commission as assistant surgeon. Her competence was attested and approved, yet as the Army Regulations did not authorize the employment of women as surgeons, her petition was denied. A Senator from New York, with an enlightenment which did him honor, urged her appointment to the Secretary of War, but without success."

He walked through the dreary hall, and looked in on the wide, vacant rooms, and passing to the front, stood for some time gazing out over the beautiful panorama, with its one great feature, the new dome of the old capitol, surmounted by a bronze statue of Liberty armed, and with her back to him, gazing seaward. From this he passed to the garden, and looked over the line of the officers' graves that bound its sides, saw the dying flowers and wilted borders and leaf strewn walks, and continuing after a slight pause, he stopped on the edge of the field where the sixteen thousand Union soldiers lie buried in lines, as if they had lain down after a review to be interred in their places. Some negroes were at work here raking up the falling leaves, and one old man stopped suddenly and stared at the visitor as if struck mute with astonishment. He continued to gaze in this way until the stranger, walking slowly, regained his horse and rode away, when he dropped his rake and said to his companions: "Shuah as de Lord, men, dat was ole Massa Lee!"
