On the morning of the 17th a breeze from the south swept up the valley, rolling dark clouds upon the mountains. There was a light fog upon the Antietam. Long before daylight the word, which roused the men from sleep, passed along the lines of Hooker's divisions. Without a drum-beat or bugle-call the soldiers rose, shook the dewdrops from their locks, rolled their blankets, and ate their breakfast.

The pickets of the two armies were so near each other that each could hear the rustle of the corn as they paced to and fro amid the rows. Occasionally there was a shot. Once, in the night, there was a volley beyond the woods towards Muma's. General Hooker was asleep in a barn near Hoffman's. He sprang to his feet, stood by the door, and listened. "We have no troops in that direction. They are shooting at nothing," he said, and lay down once more.

HOOKER'S ATTACK.

Five o'clock. It is hardly daylight, as the pickets, straining their sight, bringing their muskets to a level with their eyes, aim at the dusky forms stirring amid the corn-leaves, and renew the contest. There are bright flashes from the strip of woods, and from the ridge behind Poffenberger's. The first Rebel shell bursts in the Sixth Wisconsin, prostrating eight men. Hooker's guns, in the edge of the woods west of Hoffman's, are quick to respond.

Meade's division, composed of Seymour's, Magilton's, and Anderson's brigades, was in the center of Hooker's corps, and also in the advance. Doubleday was on the right, and Ricketts behind Meade.

The order was given to Meade to move on, and to Ricketts and Doubleday to keep within close supporting distance. The direction taken by Meade brought him through the strip of woods northeast of Miller's house. Lawton's division of Jackson's corps held the ground by Miller's house, with Ripley, of D. H. Hill's division, joining on the narrow road north of Muma's, a quarter of a mile in front of the church.

At this early hour, before any movement was made, Tuft, Langner, Von Kleizer, Weaver, Weed, and Benjamin, with twenty-pounder Parrott guns, planted on the hills east of the Antietam, between the center and lower bridges, opened upon Lee's lines, throwing shells and solid shot into Sharpsburg, and upon D. H. Hill on Rulet's farm. "It enfiladed my line, and was a damaging fire,"[62] says Stonewall Jackson, who brought up his batteries of heavy guns,—Prague's, Carpenter's, Raine's, Brokenbrough's, Caskie's, and Wooding's batteries.

Meade's men went cheerily to the work. They began at long range to give their volleys; they were in the hollow, northeast of Miller's. Lawton's troops looked down upon them from their shelter beneath the trees and behind the hills.

The Reserves began to drop beneath the galling fire. Hooker rode up to them upon a powerful white horse. The bullets flew past him, cutting down the corn, and bursting shells sprinkled him with earth; but he was calm amid it all, directing the troops and holding them up to the work by his mighty will.

Nearer to the woods now, shorter the range, more deadly the fire. Ricketts came up on the left with Duryea's and Christian's brigades.
