November 5, 1862 - Maj. Gen. George B. McClellan (right) is removed from command of the Army of the Potomac. A veteran of the Mexican-American War, McClellan quickly gained notice during the Civil War for several minor victories in western Virginia. Elevated to lead Union forces around Washington, he proved a superb organizer and created the Army of the Potomac. A cautious and timid field commander, he often believed that he was outnumbered and frequently clashed with Pres. Abraham Lincoln. Defeated on the Peninsula in the summer of 1862, he failed to crush Gen. Robert E. Lee at Antietam that September. Relieved in November, "Little Mac" ran for president in 1864, but was defeated by Lincoln.
