Not until all her stores were exhausted and she was sick with a fever would Clara Barton leave the battle-field of Antietam; then, dragging herself to the train, she went back to Washington to be taken care of until she was better. When at last she was strong enough to work again she went to see her friend Quartermaster-General Rucker, and told him that if she had had five wagons she would have had enough supplies for all the wounded at Antietam. With an expression of intense admiration on his soldierly face as he watched the brave volunteer nurse, he declared: "You shall have enough next time!" The promise was made good. Having recognized the value of her efficient services, the Government assisted in every way, making it possible for her to carry on her work on the battle-fields and in military camps and hospitals in the best way. Clara Barton!--Only the men who lay wounded or dying on the battle-field knew the thrill and the comfort that the name carried. Again and again her life was in danger--once at Antietam, when stooping to give a drink of water to an injured boy, a bullet whizzed between them. It ended the life of the poor lad, but only tore a hole in Clara Barton's sleeve. And so, again and again, it seemed as if a special Providence protected her from death or injury. At Fredericksburg, when the dead, starving and wounded lay frozen on the ground, and there was no effective organization for proper relief, with swift, silent efficiency Clara Barton moved among them, having the snow cleared away and under the banks finding famished, frozen figures which were once men. She rushed to have an old chimney torn down and built fire-blocks, over which she soon had kettles full of coffee and gruel steaming. As she was bending over a wounded rebel, he whispered to her: "Lady, you have been kind to me ... every street of the city is covered by our cannon. When your entire army has reached the other side of the Rappahannock, they will find Fredericksburg only a slaughter-pen. Not a regiment will escape. Do not go over, for you will go to certain death." She thanked him for the kindly warning and later told of the call that came to her to go across the river, and what happened. She says: "At ten o'clock of the battle day when the rebel fire was hottest, the shells rolling down every street, and the bridge under the heavy cannonade, a courier dashed over, and, rushing up the steps of the house where I was, placed in my hand a crumpled, bloody piece of paper, a request from the lion-hearted old surgeon on the opposite shore, establishing his hospitals in the very jaws of death: "'Come to me,' he wrote. 'Your place is here.'
