Immediately after the battles of Chancellorsville she went to United States Ford, but was not allowed to cross, and joined two Maine ladies at the hospital on the north side of the Rappahannock, where they dressed wounds until dark, slept in an ambulance, and early in the morning went to work again, but were soon warned to leave, as it was supposed that the house used as a hospital would be shelled. They left, and about half a mile farther on found the hospital of the Third and Eleventh Corps. Here the surgeon in charge urged Mrs. Husband to remain and assist him, promising her transportation. She accordingly left her ambulance and dressed wounds until midnight. By this time the army was in full retreat and passing the hospital. The surgeon forgot his promise, and taking care of himself, left her to get away as best she could. It was pitch dark and the rain pouring in torrents. She was finally offered a part of the front seat of an army (medicine) wagon, and after riding two or three miles on the horrible roads the tongue of the wagon broke, and she was compelled to sit in the drenching rain for two or three hours till the guide could bring up an ambulance, in which she reached Falmouth the next day.
The hospital of which she was lady matron was broken up at the time of this battle, but she was immediately installed in the same position in the hospital of the Third Division of the Third Corps, then filled to overflowing with the Chancellorsville wounded. Here she remained until compelled to move North with the army by Lee's raid into Pennsylvania in June and July, 1863.
On the 3d of July, the day of the last and fiercest of the Gettysburg battles, Mrs. Husband, who had been, from inability to get permission to go to the front, passing a few anxious days at Philadelphia, started for Gettysburg, determined to go to the aid and relief of the soldier boys, who, she well knew, needed her services. She reached the battle-field on the morning of the 4th by way of Westminster, in General Meade's mail-wagon. She made her way at first to the hospital of the Third Corps, and labored there till that as well as the other field hospitals were broken up, when she devoted herself to the wounded in Camp Letterman. Here she was attacked with miasmatic fever, but struggled against it with all the energy of her nature, remaining for three weeks ill in her tent. She was at length carried home, but as soon as she was convalescent, went to Camp Parole at Annapolis, as agent of the Sanitary Commission, to fill the place of Miss Clara Davis, (now Mrs. Edward Abbott), who was prostrated by severe illness induced by her severe and continued labors.
