engagement as the arrival of reinforcements engaging with Lee's infantry, Humphreys ordered another futile attack, which was repulsed by the Confederates. Colonel (Brevet Brigadier General) John Irvin Gregg was taken prisoner by the Confederates in the cavalry engagement. Since no reinforcements could quickly reach Humphreys and night was approaching, Humphreys ordered no further attacks. The II Corps had at least 571 casualties in the Battle at Cumberland Church and the cavalry had 74 in what is sometimes called the Battle of Farmville. Confederate casualties are unknown but have been estimated to be about half the number of the Union casualties. The National Park Service gives the number of Confederate casualties as 255. Realizing that the Union forces could close in on his men at Cumberland Church, General Robert E. Lee withdrew his army in another night march to the west at about 11:00 p.m. Although the Confederates held back the Union Army at Cumberland Church and had fewer casualties, they were delayed in their march, which helped other Union forces south of the Appomattox River to pass them and cut them off at the Battle of Appomattox Court House. Background Retreat from Sailor's Creek Because of the need to reduce steep grades in the vicinity of Farmville, the South Side Railroad crossed from the south side of the Appomattox River to the north side over the High Bridge east of Farmville, about from Rice's Station. From High Bridge, the railroad ran parallel to the north bank of the river until it reached Farmville, Virginia, to the southwest. At Farmville, the railroad crossed back to the south side of the river and proceeded to the west. The railroad bridge at Farmville also had an adjacent wagon bridge. After the Battle of Sailor's Creek, Confederate Lieutenant General Richard H. Anderson and Major General John B. Gordon and the defeated survivors of their corps headed for the South Side Railroad's High Bridge and the wagon bridge below it to cross to the presumed relative safety of the north side of the Appomattox River. After fighting unsuccessfully to destroy the bridges after themselves, Gordon and his men followed the route of the railroad over the High Bridge, along the north bank of the river, and back to the south side of the river over the bridges at Farmville to obtain rations and then immediately return to the north side of the river from Farmville.
