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. Wheaton's attack Wheaton's division was led by the axmen and 75 skirmishers from the 37th Massachusetts Infantry Regiment armed with Spencer repeating rifles. Colonel (Brevet Brigadier General) Oliver Edwards's brigade was on the left, next to Warner's brigade. Thicker, more secure abatis and sharpened stakes slowed Wheaton's division's advance. The Massachusetts sharpshooters were able to suppress Confederate fire to allow the pioneers to open gaps in the obstructions. Edwards's men found that a moat guarded a three-gun battery past the abatis, but soldiers from the 5th Wisconsin Infantry Regiment and 37th Massachusetts Infantry Regiment scaled the earthworks. In Edward's second line of battle, Lieutenant Colonel Elisha Hunt Rhodes led his 2nd Rhode Island Volunteer Infantry Regiment on a flanking maneuver down a wagon path where he could reform a battle line and cross the main Confederate line. The pickets in the rifle pits quickly surrendered. Rhodes spotted four cannons on the left and two more on the right. Rhodes and several men ran forward and jumped into the ditch in front of the line just as Lane's and Thomas's troops opened fire. The Union soldiers then quickly climbed up the exterior slope to the top of the earthworks before the Confederates could reload and fire, causing the Confederates to retreat from the onrushing Rhode Islanders. Lieutenant Frank S. Halliday and Corporal William Railton stopped a Confederate counterattack with a blast from one of two
