While attempting once again to destroy the Weldon Railroad in early January 1865 and engaging the CSA again at Hatcher's Run on February 6, the 91st Pennsylvania sustained further casualties, including Capt. John Edgar, Jr., who was killed, and Lt. William H. Frailey, who was wounded. In addition, Capt. George P. Finney was captured, as were several other members of the regiment. Then, while fighting at Dabney's Mill in the Second Battle of Hatcher's Run and the Battle of Gravelly Run in late March, the regiment lost 14 more men, including Capt. Hope. During the fighting at Five Forks and Sailor's Creek, the regiment had less costly successes, however, and was able to assist in the capture of supply wagons and CSA troops while driving the larger body of the CSA toward the Appomattox Court House. While there, the 91st Pennsylvanians witnessed the formal surrender on April 9, 1865 of the Confederate States Army by Gen. Robert E. Lee.
