The second agent, Mary Elizabeth Bowser, was part of a Union spy ring known as "the Richmond underground," directed by Elizabeth Van Lew, whose family was well respected and well connected socially in Richmond. While not hiding her Union loyalties, Van Lew affected behavior that made her appear harmless and eccentric to Confederate authorities. After the war, she traveled to Washington and obtained all the official records from the War Department related to her activities and destroyed them. Thus, details on Bowser's specific activities are sparse.
