At Gettysburg on 1 July, the 45th NC regiment advanced with the 2nd NC Battalion on their left, encountering and driving back the 149th Pennsylvania regiment at a steep railroad cut (the cut north of the McPherson barn, not the one made famous earlier in the morning by the 6th Wisconsin just to the east). This was about 2:15 p.m. according to my calculations. Some men in the 45th went down into the cut and helped escort some trapped Union prisoners to the rear, while the rest of the 45th NC continued to fire from their position along the northern rim of the cut, which served as an effective barrier to movement. The 149th PA advanced to the south side of the same cut about 2:40 p.m., this time forcing the 45th NC to fall back a short distance. I would estimate that the bulk of the 45th's casualties on the first day arose from these two brief but violent actions and their opponent in both instances was the 149th Pennsylvania.
