Battle of Chancellorsville
After the Battle of Fredericksburg the Union army was in a state of confusion. The Army of the Potomac was commanded by Major general Ambrose Burnside. But his generals were in near open revolt against Burnside feeling he was unfit to command. Burnside even seemed to agree with them. He had refused command of the Army of the Potomac twice saying he was not up to the job. Finally, President Abraham Lincoln agreed and replaced Burnside with General Joseph Hooker. Hooker managed to restore the health and morale of his army within a few weeks. He proudly called them "the finest army on the planet."
