The Seat of War

As commander-in-chief of the Union forces, Lincoln oversaw one of the largest military operations in history. To win the war, the North had to conquer the Confederacy, which encompassed 750,000 square miles, stretching from the Atlantic Ocean to areas west of the Mississippi River. This map features images of President Lincoln and Secretary of State William H. Seward above those of Winfield Scott (lower left), Lincoln’s original general-in-chief of the army known as “Old Fuss and Feathers,” and Scott’s successor, George B. McClellan.
