Inscription: "In June 1863, Gen. Robert E. Lee led the Army of Northern Virginia through gaps in the nearby Blue Ridge Mountains and into the Shenandoah Valley to invade the North. Maj. Gen. J.E.B. Stuart's cavalry corps screened the army from Federal observation. The Union cavalry commander, Brig. Gen. Alfred Pleasonton attempted to break through Stuart's screen, and fought three sharp engagements along this road. They included the Battles of Aldie (17 June), Middleburg (19 June), and Upperville (21 June). Stuart fell back westward under Pleasonton's pressure but kept the Federal cavalry east of the gaps."
