But it was no mere triumphal march. They met stern and desperate resistance. It was American against American. Once more the superb Northern batteries met those of the South with a fire as terrible as their own. The Union gunners willingly exposed themselves to death to save their army, and from their breastworks sixty thousand riflemen sent vast sheets of bullets.

But the Northern leader was gone. As Hooker leaned against a pillar in the portico of the Chancellor House a shell struck it over his head, the concussion being so violent that he was thrown to the floor, stunned and severely injured. He was carried away, unconscious, but the brave and able generals under him still sustained the battle, and had no thought of yielding.

The Southern army, Lee and Stuart in unison, never ceased to push the attack. The forces were now drawing closer together. The lines were shorter and deeper. The concentrated fire on both sides was appalling. Bushes and saplings fell in the Wilderness as if they had been levelled with mighty axes.

Harry saw a vast bank of fire and smoke and then he saw shooting above it pyramids and spires of flame. The Chancellor House and all the buildings near it, set on fire by the flames, were burning fiercely, springing up like torches to cast a lurid light over that scene of death and destruction. Then the woods, despite their spring sap and greenness, caught fire under the showers of exploding shells, and their flames spread along a broad front.

The defense made by the Union army was long and desperate. No men could have shown greater valor, but they had been surprised and from the first they had been outgeneralled. An important division of Hooker's army had not been able to get into the main battle. The genius of Lee gathered all his men at the point of contact and the invisible figure of Jackson still rode at the head of his men.

For five hours the battle raged, and at last the repeated charges of the Southern troops and the deadly fire of their artillery prevailed.

The Northern army, its breastworks carried by storm, was driven out of Chancellorsville and, defeated but not routed, began its slow and sullen retreat. Thirty thousand men killed or wounded attested the courage and endurance with which the two sides had fought.

The Army of the Potomac, defeated but defiant and never crushed by defeat, continued its slow retreat to Fredericksburg, and for a little space the guns were silent in the Wilderness.

The men of Hooker, although surprised and outgeneralled, had shown great courage in battle, and after the defeat of Chancellorsville the retreat was conducted with much skill. Lee had been intending to push another attack, but, as usual after the great battles of the Civil War, Chancellorsville was followed by a terrific storm. It burst over the Wilderness in violence and fury.

The thunder was so loud and the lightning so vivid that it seemed for a while as if another mighty combat were raging. Then the rain came in a deluge, and the hoofs of horses and the wheels of cannon sank so deep in the spongy soil of the Wilderness that it became practically impossible to move the army.
