The shells began to crash into the ranks of the Virginians and the ten thousand on their flanks. Men fell in hundreds and now the batteries on Little Round Top added to the storm of fire. The clouds of smoke gathered again, but the wind presently scattered them and Harry, waiting in agony, saw Pickett's division marching straight ahead, never faltering. But he groaned when he saw that there was trouble on the flanks. The men of Pettigrew, exhausted by the great efforts they had already made in the battle, wavered and lost ground. Another division was driven back by a heavy flank attack. Others were lost in the vast banks of smoke that at times filled the valley. Only the Virginians kept unbroken ranks and a straight course for the Union center. Pickett paused a few moments at the burning house for the others to get in touch with him, but they could not do so, and he marched on, with Cemetery Hill now only two hundred yards away. The covering fire of the Southern cannon had ceased long since. It would have been as dangerous now to friend as to foe. Harry, watching through his glasses, uttered another cry. Pickett and his men were marching alone at the hill. Half of them it seemed to him were gone already, but the other half never paused. The fire of a hundred guns had been poured upon them, as they advanced that deadly mile, but with ranks still even they rushed straight at their mark, the Union center. Then Harry saw all the slopes and the crest of Cemetery Hill blaze with fire. The Virginians were near enough for the rifles now, and the bullets came in sheets. Harry saw it, and he groaned aloud. He no longer had any hope for those brave men. The charge could not succeed! Yet he saw them rush into the Union ranks and disappear. A group in gray, still cleaving through the multitude, reappeared far up the slope, and then burst, a little band of a few dozen men, into the very heart of the Union center, the point to which they had been sent. A battle raged for a few minutes under the clump of trees where Hancock had stood directing. There Armistead, who had led them, his hat on the point of his sword, fell dead among the Northern guns, and Cushing, his brave foe who commanded the battery, died beside him. All the others fell quickly or were taken. A few hundreds on the slopes cut their way back through the Union army and reached their own. Pickett, preserved by some miracle, was among them. Harry gasped and threw down his glasses. Now he knew that the words Shepard had spoken to him the night before at the spring were true. The Southern invasion had been rolled back forever. He looked at General Lee, who on foot had been watching the charge. The impenetrable mask was gone for a moment, and his face expressed deep emotion. Then the great soul reasserted itself and mounting his horse went forward to meet the fugitives and encourage them. He rode back and forth among them, and Harry heard him say once:
