 McClellan was removed from command in November in the aftermath of the 1862 midterm elections.A major contributing factor in this decision was McClellan's failure to actively pursue Lee's Army following the tactically inconclusive but strategic Union victory at the Battle of Antietam outside Sharpsburg, Maryland.McClellan never received another field command and went on to become the unsuccessful Democratic Party nominee in the 1864 presidential election against the Republican Lincoln's reelection.
