The main result of the Battle of Chancellorsville, fought from April 30 to May 6, 1863, was a Confederate victory but at a high cost.

General Robert E. Lee's army defeated a much larger Union force led by General Joseph Hooker in a stunning tactical maneuver that showcased Lee's military genius. However, the victory came with the tragic loss of General Stonewall Jackson, who was accidentally shot by his own troops and later died from complications. This battle, while a significant Confederate win, ultimately weakened Lee’s forces and foreshadowed the challenges they would face at Gettysburg.
