First Brigade

In the Army of the Potomac's Twelfth Corps, First Division, First Brigade under Col. Archibald L. McDougall, composed of the 5th and 20th Connecticut, 3d Maryland, 123d and 145th New York, and 46th Pennsylvania Infantry, marched from Littlestown on July 1 and, when within two miles of Gettysburg, advanced on Wolf Hill, then occupied by a Confederate force, before retiring and bivouacking until morning. On July 2 it crossed Rock Creek in the morning and formed in two lines on Culp's Hill to the right of Second Division, with the rear line behind a stone wall and the front line forty yards in front, where breastworks were immediately constructed. Late in the day it went to support the Third Corps line and after dark returned to find the works and woods in the rear in possession of Major Gen. Johnson's Confederate Division. At daylight on July 3, with the artillery and infantry of the corps, the brigade attacked Major Gen. Johnson's Division, which had been reinforced from Major Gen. Early's and Major Gen. Rodes's Divisions, and at 10.30 a.m. recaptured the works after a fierce contest; in the afternoon it was sent to support the Second Corps. On July 4, the 123d New York, 5th Connecticut, and 46th Pennsylvania, with the regiments of Third Brigade and a battery, made a reconnaissance in the morning in front and to the town of Gettysburg under Col. S. Colgrove and Major Gen. H.W. Slocum and found no Confederate forces. Casualties were 1 officer and 11 men killed, 4 officers and 56 men wounded, and 1 officer and 7 men captured or missing, for a total of 80.
