Early on the morning of May 2d the cannonading began its death-song and the infantry was brought into action. Before long Jackson began, with a portion of the army, to move off the field, and Hooker, observing this, believed that Lee's army was in full retreat on Richmond. This movement proved to be the undoing of Hooker's army, as Jackson was making for his right flank. It was about five o'clock in the afternoon when Jackson broke from the woods in a charge upon the unsuspecting troops of Hooker's right which was under Howard. The approach of Jackson's forces was first intimated to the Federals by the bending of shrubbery, the stampede of rabbits and squirrels, and the flocks of birds in wild flight from the woods. First appeared a few skirmishers, then the rattling of musketry and the incessant roar of cannon. On the Confederates came in their impetuous charge. The charge was so unexpected and terrific that they carried everything before them. The Federal lines were swept as by tidal waves and rolled up like a scroll. This crowning and final stroke of Jackson's military genius was the result of his own carefully worked-out plan, which had been approved by Lee. General Hooker was spending the evening at his headquarters at the Chancellor House, rejoicing, as he thought, that Jackson was in full retreat and everything appeared to be going well. Presently the roar of battle became louder and louder on his right and an officer came up at full speed to notify him that his right was being fiercely attacked, was giving away, and would soon be in utter rout. Hooker made haste to the scene of battle and passed through brigade after brigade of his forces in retreat and confusion. He was successful in having Berry re-form his division and charge the Confederates with fixed bayonets, which partly stopped the Confederates' advance. This gave the Federal artillery a few minutes to prepare itself for action. They finally succeeded in stopping the Confederate advance. The mighty turmoil was silenced as darkness gathered. The two hostile forces were concealed in the darkness watching each other. Finally, at midnight, the order, "Forward!" was given in subdued tones to Sickle's corps. They stealthily advanced upon the Confederate position and at heavy loss gained the position sought for. Between Hooker's and Sedgwick's divisions of the army stood the Confederate army flushed with the victory of the day, immediately in front of Sedgwick was Fredericksburg, beyond which loomed Marye's Heights, strongly guarded by Washington's artillery of the Confederates. These Heights were the battleground of a few months before when Burnside tried in vain to drive the Confederates from their crest.
