On Monday (September 1) the enemy’s cavalry appeared in the wood opposite and a raid was hourly expected. In the afternoon all the wounded men were sent off and the danger became so imminent that Mrs. Fales thought best to leave, although she only went for stores. I begged to be excused from accompanying her, as the ambulances were up to the fields for more, and I knew I should never leave a wounded man there if I were taken prisoner forty times. At six o’clock it commenced to thunder and lighten and all at once the artillery began to play, joined by the musketry about two miles distant. We sat down in our tent and waited to see them break in, but Reno’s forces held them back. The old 21st Massachusetts lay between us and the enemy and they could not pass. God only knows who was lost, I do not, for the next day all fell back. Poor Kearny, Stephen, and Webster were brought in, and in the afternoon Kearny’s and Heintzelman’s divisions fell back through our camp on their way to Alexandria. We knew this was the last. We put the thousand wounded men we then had into the train. I took one carload of them and Mrs. M. another. The men took to the horses. We steamed off, and two hours later there was no Fairfax Station. We reached Alexandria at ten o’clock at night, and, oh, the repast which met those poor men at the train. The people of the island are the most noble I ever saw or heard of. I stood in my car and fed the men till they could eat no more. Then the people would take us home and feed us, and after that we came home. I had slept one and one half hours since Saturday night and I am well and strong and wait to go again if I have need. Immediately after the second Bull Run, or Manassas, followed the battle of Chantilly. It was a woeful battle for the Federal cause. The Confederates were completely successful. Pope’s army retreated to Washington in almost as great a state of panic as had characterized the army of McDowell in the previous year. Nothing saved Washington from capture but the fact that the Confederate forces had been so reduced by continuous fighting that they were unable to take advantage of their success. But they had captured the Federal wagon trains; had inflicted far greater losses than they had themselves endured, and were in so confident a frame of mind that Lee immediately prepared to cross the Potomac, invade the North, and bring the war, as he hoped, to a speedy end. It was under these conditions that Clara Barton continued her education at the battle-front. Among many other experiences on the field of Chantilly, Miss Barton recalled these incidents:
