Confederate reinforcements deployed into battle line at the edge of the woods behind you. Anchoring the center of this new position stood a brigade of Virginians - 2,500 strong - under the command of General Thomas J. Jackson. When told the enemy was driving the Confederates, Jackson calmly replied, "We will give them the bayonet."
Jackson's determined resistance on Henry Hill drew the attention of General Barnard Bee. Attempting to rally the remnants of his brigade, Bee shouted, "Look! There stands Jackson like a stone wall! Let us go to his assistance!" The nickname spread rapidly through the Confederate army and throughout the South. "Stonewall" Jackson was on his way to becoming a legend.
