As Hooker moved to crush Lee’s army, however, Lee learned of an unprotected route through the woods that might allow him to unleash a surprise assault on his enemy’s right flank. Departing from basic military doctrine — never divide your force in the face of a superior enemy — Lee sent General Stonewall Jackson and 30,000 troops on a day-long forced march to set up the flank attack. It was a dangerous risk: Lee was left with barely 15,000 men to hold off the Federal advance. He deceived and stalled Hooker by feigning an assault — buying the time needed for Jackson to organize and launch his surprise attack.

That afternoon, May 2nd, Jackson’s troops charged screaming from the forest and struck Hooker’s right flank a mighty blow that sent the Federal XI Corps reeling in retreat. Instead of the success he had proudly predicted, Hooker was dealt the same humiliating defeat that Lee had inflicted on the previous Federal army commanders. It was a might victory for Lee and Jackson, but it was a costly one: Stonewall Jackson would soon die of complications from battle wounds suffered at Chancellorsville. Looming ahead, too, was the battle of Gettysburg and the death of Southern dreams. For the moment, however, the Army of Northern Virginia was again victorious. As he moved among his army near the blazing Chancellor house the next morning, General Lee was mobbed by his cheering troops. Again, they had done the impossible. Again, they had turned back the invader. The triumph at Chancellorsville was Robert E. Lee’s supreme moment.
