While the Vermont Brigade breached the Confederate line on the left flank of the Union attack, to their right Colonel Thomas W. Hyde's brigade became disorganized in the darkness. Ultimately the men who maintained the attack and reached the fortifications jumped over the works and broke the Confederate line. To the right of Hyde's brigade, Colonel (Brevet Brigadier General) James M. Warner's brigade's lead regiment, the 102nd Pennsylvania Infantry, became disoriented in the near darkness and over the swampy ground after taking the rifle pits. Just after Colonels Tracy's and Hyde's men had broken the Confederate line, the 139th Pennsylvania Infantry Regiment under Major James McGregor closed the gap with the 102nd Pennsylvania Infantry and moved forward with some of their men and the 93rd Pennsylvania Infantry. Major James A. Weston later wrote that his 33rd North Carolina Infantry Regiment amounted to a mere skirmish line and was overcome by sheer force of numbers, although McGregor wrote that the Confederates appeared glad to surrender when the Pennsylvanians reached their line. With this action, half of Lane's brigade had been overcome by Getty's division.
