They were almost at the bottom where the valley opened out in grass land, and were turning northward when Harry saw two figures ahead of them among the trees. They were men in blue uniforms with rifles in their hands, and they were staring in surprise at the advancing columns in gray. But their surprise lasted only a moment. Then they lifted their rifles, fired straight at the Invincibles, and with warning shouts darted among the trees toward their own troops. "Forward, lads!" shouted Colonel Talbot. "We're within four hundred yards of the fort, and we must rush it! Officers, to your places!" Their own bugle sang stirring music, and the men gathered themselves for the forward rush. Up shot the sun, casting a sharp, vivid light over the slopes and valley. The soldiers, feeling that victory was just ahead, advanced with so much speed that the officers began to check them a little, fearing that the Invincibles would be thrown into confusion. The forest ended. Before them lay a slope, from which the bushes had been cut away and beyond were trenches, and walls of fresh earth, from which the mouths of cannon protruded. Soldiers in blue, sentinels and seekers of wood for the fires, were hurrying into the earthworks, on the crests of which stood men, dressed in the uniforms of officers. "Forward, my lads!" shouted Colonel Leonidas Talbot, who was near the front rank, brandishing his sword until the light glittered along its sharp blade. "Into the fort! Into the fort!" The sun, rising higher, flooded the slopes, the valley, and the fort with brilliant beams. Everything seemed to Harry's excited mind to stand out gigantic and magnified. Black specks began to dance in myriads before his eyes. He heard beside him the sharp, panting breath of his comrades, and the beat of many feet as they rushed on. He saw the Northern officers on the earthwork disappear, dropping down behind, and the young Southern soldiers raised a great shout of triumph which, as it sank on its dying note, was merged into a tremendous crash. The whole fort seemed to Harry to blaze with red fire, as the heavy guns were fired straight into the faces of the Invincibles. The roar of the cannon was so near that Harry, for an instant, was deafened by the crash. Then he heard groans and cries and saw men falling around him. In another moment came the swish of rifle bullets, and the ranks of the Invincibles were cut and torn with lead. The young recruits were receiving their baptism of fire and it was accompanied by many wounds and death.
