Edwin M. Stanton, Mathew B. Brady & Co., c. 1862

Secretary of War

Lincoln appointed Edwin M. Stanton as his second secretary of war after removing Simon Cameron from office amidst scandal on January 13, 1862. Stanton, a Democrat from Ohio, had formerly served as attorney general under President James Buchanan. Stanton initially criticized Lincoln’s conduct of the war, but he grew to respect and admire the president, who nicknamed him “Mars.”
