The Battle of Dinwiddie Court House was fought on March 31, 1865, during the American Civil War at the end of the Richmond-Petersburg Campaign and in the beginning stage of the Appomattox Campaign. Along with the Battle of White Oak Road which was fought simultaneously on March 31, the battle involved the last offensive action by General Robert E. Lee's Confederate Army of Northern Virginia attempting to stop the progress of Lieutenant General Ulysses S. Grant's Union Army. Grant's forces were moving to cut the remaining Confederate supply lines and to force the Confederates to extend their defensive lines at Petersburg, Virginia and Richmond, Virginia to the breaking point, if not to force them into a decisive open field battle.

George Armstrong Custer was a United States Army officer and cavalry commander in the American Civil War and the American Indian Wars.
