The battle of Chancellorsville was a major battle that occurred from 27 April to 6 May 1863. The Union Army under the command of Major General Joseph “Fighting Joe" Hooker attacked the Confederate Army under the command of General Robert E. Lee near the town of Chancellorsville, Virginia. Major General Hooker, commanded approximately 130,000 men. General Lee was in command of the Confederate Army of approximately 60,000 men.
