By the afternoon of April 7, Mahone and Gordon had entrenched on high ground at Cumberland Church and soon were joined by the remainder of the Confederate Army. Upon his II Corps being shelled when they approached the Confederate line, Humphreys attacked the Confederate position bringing on the Battle of Cumberland Church. Not realizing that other Union infantry could not cross the Appomattox River at Farmville and reinforce him, Humphreys made a second futile attack when he heard the sound of battle nearby, which he thought was another Union infantry attack on the Confederate line. He had heard what has sometimes been called the Battle of Farmville rather than part of the Battle of Cumberland Church, which was an engagement between part of Crook's cavalry division and Confederate cavalry guarding a wagon train headed west. The Confederate cavalry surprised the leading Union troopers and inflicted 74 casualties, among which were many prisoners including Union Brigadier General J. Irvin Gregg. Either the Confederates drove the Union force back across the river, or coincidentally at about this time, Sheridan recalled Crook to Farmville and, in any event, Sheridan directed Crook to move his division to Prospect Station, west of Farmville. Crook's division arrived at Prospect Station about midnight.
