When war came, Dame, aged 46, approached the recruit training station at Camp Union in Concord and offered her services to officers there. She was appointed matron of the 18th Army Corps hospital in September 1864. Her duties included supervising other nurses, and cooking for the hospital patients, often numbering in the thousands. Marston said of her: "Miss Dame was the bravest woman I ever knew. I have seen her face a cannon battery without flinching while a man took refuge behind her for safety from flying shells. She was always present when most needed." Dame's nursing duties varied as well; sometimes she would oversee supplies, other times she would investigate the sanitary conditions of other regiments. She was twice captured in battle, and released by her captors. At the
Second Battle of Bull Run, Dame was taken as a prisoner but released because she cared for
Union and
Confederate soldiers indiscriminately. In once instance,
Stonewall Jackson authorized her return to Union lines. ==Post-war life==
