First Army Corps.

Maj. Gen. Joseph Hooker, Commanding.
September 16, 1862.

The First Army Corps moved from its bivouac near Keedysville at 2 p.m. on Sept 16. Doubleday's Division crossed the Antietam at Pry's Ford; Rickett's and Meade's Divisions at the upper bridge.

The divisions advanced in parallel columns, in a westerly direction, until 6 p.m., when Meade's Division encountered the enemy near the East Woods.

The corps was then formed in line of battle, facing south and south-west, Meade's Division in the center, somewhat advanced. Doubleday's Division on the right and Ricketts' Division on the left in supporting distance.

The fighting ceased on account of darkness at about 6:30 p.m.

5. Major General Joseph Hooker (1814-1879)
At Antietam, his corps launched the first assault of the bloodiest day in American history, driving south into the corps of Lt. Gen. Stonewall Jackson, where they fought each other to a standstill. Hooker, aggressive and inspiring to his men, left the battle early in the morning with a foot wound. He asserted that the battle would have been a decisive Union victory if he had managed to stay on the field, but General McClellan's caution once again failed the Northern troops and Lee's much smaller army eluded destruction.
