Then with a shout the Invincibles, their officers at their head, plunged into the fire and smoke, and were lost from Harry's view. But he could not stay there long and wonder at their fate. In a few minutes he was riding to Longstreet with a message for him to bear steadily toward Hill, that the gap might be closed entirely, and as soon as possible. He galloped behind the lines, but bullets fell all around him, and often a shell tore the earth. The air had become more bitter and poisonous. Fumes from swamps seemed to mingle with the smoke and odors of burned gunpowder. His lips and his tongue were scorched. But he kept on, without exhaustion or mishap, and reached Longstreet, who had divined his message. "The line will be solid in a few minutes," he said, and while the battle was still at its height on the long front he touched hands with Hill. Then both drove forward with all their might against Hancock, rushing to the charge, with the Southern fire and recklessness of death that had proved irresistible on so many fields. The advance, despite the most desperate efforts of Hancock and his generals, was stopped. Then he was driven back. All the ground gained at so much cost was lost and the Southern troops, shouting in exultation, pushed on, pouring in a terrible rifle fire. Longstreet, in his eagerness, rode a little ahead of his troops to see the result. Turning back, he was mistaken in the smoke by his own men for a Northern cavalryman, and they fired upon him, just as Jackson had been shot down by his own troops in the dusk at Chancellorsville. The leader fell from his horse, wounded severely, and the troops advancing to victory became confused. The rumor spread that Longstreet had been killed. There was no one to give orders, and the charge stopped. Harry and a half-dozen others who had seen the accident or heard of it, galloped to Lee, who at once rode into the very thick of the command, giving personal orders and sending his aides right and left with others. The whole division was reformed under his eye, and he sent it anew to the attack. The battle now closed in with the full strength of both armies. Hancock strove to keep his place. The valiant Wadsworth had been killed already. The dense thickets largely nullified Grant's superior numbers. Lee poured everything on Hancock, who was driven from every position. Fighting furiously behind a breastwork built the night before, he was driven from that too. Often in the dense shades the soldiers met one another face to face and furious struggles hand-to-hand ensued. Bushes and trees, set on fire by the shells, burned slowly like torches put there to light up the ghastly scene of man's bravery and folly. Jenkins, a Confederate general, was killed and colonels and majors fell by the dozen. But neither side would yield, and Grant hurried help to his hard-pressed troops.
