In November the Seventh moved to Fort Sedgwick, also known as Fort Hell as it was the closest fort at Petersburg to the Confederate line. The men lived underground in shelters known as “bombproofs” to escape the murderous fire outside. The Seventh remained here until April 2, 1865, when they helped storm into Petersburg and then pursued Lee to Appomattox Court House. The original regiment was mustered out of the service on June 9, 1864, while the recruits were mustered out on July 13, 1865. 1,282 men served in the Seventh Rhode Island; 220 died. On March 13, 1865 General Ulysses S. Grant formally gave his permission for the Seventh Rhode Island Volunteers to paint the following engagements upon their colors where they had fought and died: Fredericksburg, Vicksburg, Jackson, Spotsylvania, North Anna, Cold Harbor, Petersburg, Weldon Railroad, Poplar Spring Church, and Hatcher’s Run.
