William E. Barton The Life of Clara Barton, Founder of the American Red Cross… (1922)

But it was only when in the hush of the following day, as we glanced over that vast Aceldama, that we learned at what a fearful cost the gallant Union army had won the battle of Antietam.
Antietam! With its eight miles of camping armies, face to face; 160,000 men to spring up at dawn like the old Scot from the heather! Its miles of artillery shaking the earth like a chain of Ætnas!

The Battle of Antietam, in its effects, was a brilliant and decisive victory for the Union arms, as it was a terrible blow to the South, who had expected much from Lee's sudden and daring invasion of a loyal state; and their losses, from the time they first invaded Maryland until the end of the Battle of Antietam, were in the neighborhood of thirty thousand men.

Gen. A. P. Hill’s division, left behind by Jackson at Harpers Ferry to salvage the captured Federal property, arrived on the field and immediately entered the fight. Burnside’s troops were driven back to the heights near the bridge they had earlier taken. The Battle of Antietam was over. The next day Lee began withdrawing his army across the Potomac River.
“If I cannot whip Bobbie Lee, I will be willing to go home.”
George B. McClellan
More men were killed or wounded at Antietam on September 17, 1862, than on any other single day of the Civil War.
