Also called the Battle of Dabney’s Mill. On February 5, 1865, Gregg's Union cavalry division moved towards Ream's Station and the Dinwiddie Court House. Their mission was to raid and cut off Confederate supply trains. He was supported by Union General Warren's V Corps who took up a blocking position to stop any Confederate interference. Major General Andrew A. Humphreys's II Corps moved west to cover V Corps' right flank. That night, two more divisions reinforced the Union positions. But the raid was unsuccessful. As Gregg's cavalry was returning they were attacked by Confederate divisions led by Generals John Pegram and William Mahone. The Union advance was stopped although General Pelgram was killed in the battle. But the Union Army gained more territory as the line was now extended to Hatcher's run. Total casualties in the action were 2,700.
