A glance at the casualties will show this.

They were remarkable.

General Lawton, division commander, was wounded and carried from the field; Colonel Douglas, brigade commander, was killed; Colonel Walker, also commanding brigade, was disabled; Lawton's brigade lost five hundred and fifty-four killed and wounded out of eleven hundred and fifty, and five out of six regimental commanders.

Hayes's brigade lost three hundred and twenty-three out of five hundred and fifty, and all the regimental commanders.

Walker's brigade lost two hundred and twenty-eight out of less than seven hundred, and three out of four regimental commanders; and, of the staff-officers of the division, scarcely one remained.
In an hour after dawn, this heavy slaughter had been effected in Ewell's division, and the detailed statement which we have given will best show the stubborn resistance offered by the Southern troops.
Still, they were unable to hold their ground, and fell back at last in disorder before General Hooker, who pressed forward to seize the Hagerstown road and crush the whole Confederate left.
