Col. Edward Harland, 8th Connecticut Infantry, Commanding.
On the morning of the 17th, Harland's Brigade moved from its position southeast of Burnside Bridge. The 11th Connecticut, deployed as skirmishers, preceded Crook's Brigade in its assault on the bridge and was repulsed with great loss. During the forenoon the remaining Regiments of the Brigade moved down the left bank of the Antietam, crossed at Snavely's Ford and, moving up the right bank of the stream, formed line on the left of the Division, Ewing's Ohio Brigade in support. At about 3 P.M., the Brigade advanced in the direction of Sharpsburg. The 8th Connecticut passed to the west of this point and the 16th Connecticut and 4th Rhode Island were in the 40 acre cornfield east, when they were attacked in flank by the right of A.P. Hill's Division and compelled to retire to the cover of the high ground near the bridge.
