Major General George B. McClellan and his wife Ellen Mary Marcy are shown together in this carte de visite that was part of a collection of Maine soldier Maj. Abner B. Small of Waterville, who served in the 3rd Maine before receiving a commission in the newly formed 16th Maine Regiment.

McClellan, a graduate of the University of Pennsylvania and West Point, commanded the Army of the Potomac and served as general-in-chief of the Union armies before President Abraham Lincoln relieved him of his duties for failing to carry out orders and attack the Confederate army.

McClellan, who was popular with soldiers, ran as a Democrat against Lincoln in 1864.
