The bitter Union defeat at Fredericksburg prompted President Lincoln to appoint Joseph Hooker as the next commander of the Army of the Potomac. In May 1863, Hooker maneuvered to attack Lee's army by crossing the Rapahannock further upriver and positioning himself at the Chancellorsville crossroads. Doing this could give him an opportunity to strike Lee in the rear, but the Confederate General barely managed to pivot his forces in time to face an attack. Hooker's command was nearly twice the size of Lee's but he nonetheless was beaten after Lee performed a daring movement that broke all terms of conventional warfare: dividing his army. Lee sent Stonewall Jackson's corps to attack Hooker's exposed flank, on the opposite side of the battlefield. The significant victory that followed came with a price. Among the heavy casualties was Jackson, his finest corps commander, accidentally fired on by his own troops.
