(September 17, 1862.)
The Brigade assisted in carrying the Burnside Bridge, and crossed it soon after 1 P.M. After the repulse of the three Divisions of Willcox, Scammon and Rodman later in the day Ferrero's and Nagle's Brigades advanced to the crest of the ridge about 420 yards east of this to check Confederate pursuit. The 48th Pennsylvania supported and relieved the 51st Pennsylvania, engaging the Confederates posted on this line and behind the stone walls right and left of this point. The engagement continued into the night, and the Regiment and Brigade bivouacked on the ground on which they had fought.
