Battle of Fredericksburg
Despite winning what seemed like a lopsided battle, Lee lost men and equipment he could not afford to lose. Burnside's losses, although great, were soon replaced. Lee suffered 5,300 casualties defending Fredericksburg. Union losses were more than double. Burnside lost about 12,600 Union soldiers; killed, wounded, or missing. The Battle of Fredericksburg was depressing news to the North. But it had no lasting impact on the war. It was a boost to Confederate morale however. The spring would see a new campaign against Richmond. In January 1863, Burnside was replaced as commander of the Army of the Potomac by General Joseph Hooker. But Like Burnside, Hooker would be replaced after a single disastrous battle—the Battle of Chancellorsville. But following the Battle of Fredericksburg, the Army of the Potomac engaged in what came to be called the Mud March, an aborted attempt at a winter campaign.
