"After its organization, the regiment left New York on April 29, 1862, and proceeded to Washington. After encamping there for about three weeks it was ordered to Harper's Ferry, Va., where it arrived May 26th, in company with other troops which were hurried to that point on account of Jackson's pursuit. In June, the Seventy-eighth was assigned to Greene's Brigade of Auger's Division, Banks Corps, in which command it was present at the battles of Cedar Mountain and Second Bull Run."
Their commander, Colonel Daniel Ullmann, was captured at Cedar Mountain (9 August 1862), and spent the next 2 months at Libby Prison, Richmond.
The designation of Banks's Corps was changed to XII Corps, Army of the Potomac, with General Mansfield taking command from Banks. General Augur was wounded at Cedar Mountain, and General Greene was placed in command of the division.
On the Antietam Campaign
"Lieut. Col. Jonathan Austin commanded the Seventy-eighth at the battle of Antietam, the regiment going into action with 12 officers and 209 men. Colonel Goodrich, of the Sixtieth New York, who was in command of the brigade, was killed early in the fight, and the command devolved on Lieutenant Colonel Austin. Capt. Henry R. Stagg took charge of the regiment. Entering the action early in the morning Greene's Division was actively engaged until noon or after, having pushed its way into the woods behind the Dunker Church, where it held the most advanced position on the entire Union line, and held it for two hours or more. The Seventy-eighth fought with conspicuous gallantry, executing every movement as steadily as if on battalion drill. Capt. Peter M. Mitchell was killed, and Lieut. Peirson B. Peterson fell mortally wounded. The official report mentions "the daring and courage of Lieutenant Colonel Austin," and "the valuable services of Lieutenant McGregor of the Seventy-eighth New York, the latter having charge of the skirmishers."
