But the shell fell short and exploded on the slope.
"Now listen, will you!" exclaimed Harry. "That's the spirit!"
Immediately after the shell burst a Southern band began to play. And it played the merriest music, waltzes and polkas and all kinds of dances. Harry felt his feet move to the tunes, while the battle below, at its very height, roared and thundered.
But he promptly forgot the musicians as he watched the battle. He knew that the Invincibles were somewhere in that volcano of fire and smoke, and it was almost too much to hope that they would again come unhurt out of such a furious conflict. But they, too, passed quickly from his mind. The struggle would let nothing else remain there long.
He saw that the Union troops were still in the Peach Orchard and that they were pouring a deadly fire also from Little Round Top. Hancock had come to take the place of Sickles, and he was drawing every man he could to his support. The afternoon was waning, but the battle was still at its height. Men were falling by thousands, and generals, colonels, majors, officers of all kinds were falling with them. The Southerners had not encountered such resistance in any other great battle, and the ground, moreover, was against them.
Yet the grim fighter, Longstreet, never ceased to push on his brigades. The combat was now often face to face, and sharpshooters, hidden in every angle and hollow of the earth, picked off men by hundreds. The great rocky mass known as the Devil's Den was filled with Northern sharpshooters and for a long time they stung the Southern flank terribly, until a Southern battery, noticing whence the deadly stream of bullets issued, sprayed it with grape and canister until most of the sharpshooters were killed, while those who survived fled like wolves from their lairs.
The day was now passing, but Harry could see no decrease in the fury of the battle. Longstreet was still hurling his men forward, and they were met with cannon and rifle and bayonet. The Confederate line now grew more compact. The brigades were brought into closer touch, and, gathering their strength anew, they rushed forward in a charge, heavier and more desperate than any that had gone before. Generals and colonels led them in person. Barksdale, young, but with snow-white hair, was riding at the very front of the line, and he fell, dying, in the Union ranks.
The Southern charge was stopped again on the left wing of the Union army, and with the coming of the night the battle there sank, but elsewhere the South was meeting with greater success. Ewell, making a renewed and fierce attack at sunset, drove in the Northern right, and, seconded by Early, took their defenses there. But the darkness was coming fast, and although the firing went on for a long time, it ceased at last, with the two enemies still face to face and the battle drawn.
Harry, who had expected to see a glorious victory won by the setting of the sun, was deeply depressed. His youth did not keep him from seeing that very little advantage had been won in that awful conflict of the afternoon, and he saw also that the Army of the Potomac had been fighting as if it had been improved by defeat. Nor had Lee thrown in his whole force where it was needed most. If Jackson had only been there! Harry pictured his swift flank movement, his lightning stroke, and the crumpling up of the enemy. Jackson loomed larger than ever now to his disappointed and excited mind.
Harry had been all day long and far into the night on Seminary Hill. Often he had scarcely moved for an hour, and now, when the firing ceased and he stood up and tried to peer into the valley of death, he found his limbs so stiff for a minute or two that he could scarcely move. His eyes ached and his throat was raw from smoke and the fumes of burned gunpowder. But as he shook himself and stretched his muscles, he regained firmness of both mind and body.
