The whole Southern army awoke and poured down the slopes. Yes, Milroy, not believing that he was strong enough for another battle, had gone down the valley. He had fought one good battle, but he would reach Banks before he fought another. The Southern troops felt that they had won the victory, and Jackson sent a message to Richmond announcing it. Never had news come at a more opportune time. The fortunes of the South seemed to be at the lowest ebb. Richmond had heard of the great battle of Shiloh, the failure to destroy Grant and the death of Albert Sidney Johnston. New Orleans, the largest and richest city in the Confederacy, had been taken by the Northern fleet--the North was always triumphant on the water--and the mighty army of McClellan had landed on the Peninsula of Virginia for the advance on Richmond. It had seemed that the South was doomed, and the war yet scarcely a year old. But in the mountains the strange professor of mathematics had struck a blow and he might strike another. Both North and South realized anew that no one could ever tell where he was or what he might do. The great force, advancing by land to co-operate with McClellan, hesitated, and drew back. But Jackson's troops knew nothing then of what was passing in the minds of men at Washington and Richmond. They were following Milroy and that commander, wily as well as brave, was pressing his men to the utmost in order that he might escape the enemy who, he was sure, would pursue with all his power. He knew that he had fought with Stonewall Jackson and he knew the character of the Southern leader. Sherburne brought his horses through a defile into the valley and his men, now mounted, led the pursuit. Jackson in his eagerness rode with him and Harry was there, too. Behind them came the famous foot cavalry. Thus pursuer and pursued rolled down the valley, and Harry exulted when he looked at the path of the fleeing army. The traces were growing fresher and fresher. Jackson was gaining. But there were shrewd minds in Milroy's command. The Western men knew many devices of battle and the trail, and Milroy was desperately bent upon saving his force, which he knew would be overwhelmed, if overtaken by Jackson's army. Now he had recourse to a singular device. Harry, riding with Captain Sherburne, noticed that the trees were dry despite the recent rains. On the slopes of the mountains the water ran off fast, and the thickets were dry also. Then he saw a red light in the forest in front of them. General Jackson saw it at the same time. “What is that?” he exclaimed. “It looks like a forest fire, general,” replied Sherburne. “You're right, captain, and it's growing.” As they galloped forward they saw the red light expand rapidly and spread directly across their path. The whole forest was on fire. Great flames rose up the trunks of trees and leaped from bough to bough. Sparks flew in millions and vast clouds of smoke, picked up by the wind, were whirled in their faces.
