After the Fredericksburg debacle, "Fighting Joe" Hooker rebuilt and reorganized the demoralized Army of the Potomac, turning it -- once again -- into a potent fighting force. His campaign at the end of April, 1863 completely out maneuvered Robert E. Lee. Yet, after fighting from May 1 to May 4, 1863 around the area known as Chancellorsville, the Army of the Potomac was once again retreating. Lee had won an important victory, but at a high cost.
