As on the morning before, a mist arose from the Potomac and the Antietam. The sun, bright and hot, soon dispersed it. But there was no movement by either army. Dick did not hear the sound of a single shot. Warner and Pennington, recovered from their stupor, stood beside him gazing southward toward the rocks and ridges, where the Confederate army lay. “I'm thinking,” said Warner, “that they're just as much exhausted as we are. We're waiting for an attack, and they're waiting for the same. The odds are at least ninety per cent in favor of my theory. Their losses are something awful, and I don't think they can do anything against us. Look how our batteries are massed for them.” Dick was watching through his glasses, and even with their aid he could see no movement within the Southern lines. Hours passed and still neither army stirred. McClellan counted his tremendous losses, and he, too, preferred to await attack rather than offer it. His old obsession that his enemy was double his real strength seized him, and he was not willing to risk his army in a second rush upon Lee. While Dick and his comrades were waiting through the long morning hours, Lee and Jackson and his other lieutenants were deciding whether or not they should make an attack of their own. But when they studied with their glasses the Northern lines and the great batteries, they decided that it would be better not to try it. When noon came and still no shot had been fired, Colonel Winchester shook his head. “We might yet destroy the Southern army,” he said to Dick, “but I'm convinced that General McClellan will not move it.” The hot afternoon passed, and then the night came with the sound of rumbling wheels and marching men. Dick surmised that Lee was leaving the peninsula, and, crossing the Potomac in to Virginia, and that therefore tactical victory would rest with the Northern side. The noises continued all night long, but McClellan made no advance, nor did he do so the next day, while the whole Confederate army was crossing the Potomac, until nearly night. But the Winchester regiment and several more of the same skeleton character, pushing forward a little on the morning of that day, found that the last Confederate soldier was gone from Sharpsburg. Colonel Winchester and other officers were eager for the Army of the Potomac to attack the Army of Northern Virginia, while it dragged itself across the wide and dangerous ford. But McClellan delayed again, and it was sunset when Dick saw the first sign of action. A strong division with cannon crossed the river and attacked the batteries which were covering the Southern rearguard. Four guns and prisoners were taken, but when Lee heard of it he sent back Jackson, who beat off all pursuit.
