The Battle of Unison
Historical highway marker T-57_1 · Loudoun County
After the Union victory at Antietam, Md., in Sept. 1862, Pres. Abraham Lincoln ordered Gen. George McClellan and the Army of the Potomac to cross into Virginia and get between Confederate Gen. Robert E. Lee's Army of Northern Virginia and Richmond. Confederate Maj. Gen. J.E.B. Stuart and a small number of cavalrymen delayed McClellan's advance along this road, 1-3 Nov., allowing Lee time to march from the western side of the Blue Ridge and escape the trap. After this failure, Lincoln removed McClellan from command. The Unison Battlefield Historic District is listed on the Virginia Landmarks Register and the National Register of Historic Places.
