On this day 164 years ago, President Abraham Lincoln reinstated General George B. McClellan as full commander following General John Pope’s failure at the Second Battle of Bull Run in Virginia. Previously, McClellan had served as commander of the Army of the Potomac, but after his unsuccessful attempt to capture Richmond during the Seven Days Battles in June 1862, his army was transferred to Pope's newly formed Army of Virginia.
At the Second Battle of Bull Run, Confederate General Robert E. Lee overwhelmed Pope, who failed to demonstrate effective leadership and ultimately retreated to Washington, D.C. While McClellan observed the battle, he chose not to assist Pope, even though he was nearby. As a result of this defeat, Union morale plummeted.
President Lincoln believed that McClellan was the best available general to restore the spirits of the Union forces. McClellan’s strengths lay in his ability to prepare and organize an army for combat, and Lincoln recognized these talents as essential for raising morale after the Union’s setback.
