<P> The Battle of Chancellorsville was a major battle of the American Civil War ( 1861 -- 1865 ) , and the principal engagement of the Chancellorsville Campaign . It was fought from April 30 to May 6 , 1863 , in Spotsylvania County , Virginia , near the village of Chancellorsville . Two related battles were fought nearby on May 3 in the vicinity of Fredericksburg . The campaign pitted Union Army Maj. Gen. Joseph Hooker 's Army of the Potomac against an army less than half its size , General Robert E. Lee 's Confederate Army of Northern Virginia . Chancellorsville is known as Lee 's `` perfect battle '' because his risky decision to divide his army in the presence of a much larger enemy force resulted in a significant Confederate victory . The victory , a product of Lee 's audacity and Hooker 's timid decision making , was tempered by heavy casualties , including Lt. Gen. Thomas J. `` Stonewall '' Jackson . Jackson was hit by friendly fire , requiring his left arm to be amputated ; he died of pneumonia eight days later , a loss that Lee likened to losing his right arm . </P>
