The Second Battle of Ream's Station (also Reams or Reams's) was fought during the Siege of Petersburg in the American Civil War on August 25, 1864, in Dinwiddie County, Virginia. A Union force under Maj. Gen. Winfield S. Hancock began destroying part of the Weldon Railroad, which was a vital supply line for Gen. Robert E. Lee's Confederate army in Petersburg, Virginia. Lee sent a force under Lt. Gen. A. P. Hill to challenge Hancock and the Confederates were able to rout the Union troops from their fortifications at Reams Station.
