General Lee's army had seen great hardship. The Rebels had marched from Richmond. "One fifth of them were barefoot, one half of them in rags, and the whole of them famished," writes Pollard the Southern historian.[80] Lee was far from his supplies. He had no reinforcements at hand. His troops were much exhausted. A. P. Hill had marched with great rapidity from Harper's Ferry. Jackson's corps had suffered as severely as Hooker's. D. H. Hill had lost more than Sedgwick. Longstreet could hardly be a match for French, Richardson, and the whole of Franklin's corps. Lee, if defeated, had a great river in his rear which must be crossed at one ford, which would give McClellan the shortest line to Richmond. Sigel was in front of Washington. Heintzelman was at Alexandria. Keyes was at Yorktown. Could not these forces cut off his retreat to Richmond? He was in a perilous situation. He sent his wounded across the Potomac to Martinsburg and Winchester,--also his wagons, and made preparations for a rapid movement of his army into Virginia. [Footnote 80: Vol. II., p. 142.] Early in the morning I rode to the right, came upon the line by Poffenberger's. Rations had been served; and the troops were in position, expecting orders to move. Colonel Andrews, commanding Gordon's brigade in Mansfield's corps, was riding along the line. "How are your men, Colonel?" "All right. They had a pretty hard time yesterday; but having had a good breakfast, they feel well. We expect to advance in a few moments." I talked with the soldiers. "We gave them a good thrashing yesterday, and mean to drive them into the Potomac to-day," said one. The sharpshooters were lying in the field in front of the church. All were ready. At noon, I rode once more along the lines. Some of the batteries which had exhausted their ammunition in the battle had refilled their caissons, and were waiting orders to take position. The gunners were lying on the ground. "Do you think there will be a battle to-day?" I asked an officer. "O, yes. We shall be at it in a few minutes. We are all ready." One o'clock,--the wounded men were all removed. The flag of truce had been taken down. Two o'clock,--and no order to begin the attack. Officers were impatient. They wondered at the delay. I rode to Elk Ridge, and went up the mountain's side. Beyond Sharpsburg there was a cloud of dust. Baggage wagons were moving west. Lee's troops were in line, where they had been in the morning, but there were some indications of a retreat. At sunset, I looked once more from the mountain. The evidences had increased that Lee intended to cross the Potomac. The morning of the 19th dawned. Lee was gone! He took away all his artillery, except one iron gun and some disabled caissons and wagons. Riding now over all the field, I found many Rebel dead in the woods by the church. Among them were bodies clothed in the Union blue, lying where they fell, close up to the Rebel line.
