On the orders of General John Hunt Morgan, around sixty-five Confederate horsemen from the 2nd Kentucky Cavalry, led by 24-year old Captain Thomas Hines, crossed the Ohio River to gather intelligence.  Posing as Union "home guards" seeking deserters, their main mission was to gauge the amount of Confederate support in southern Indiana. They entered the towns of Paoli, Corydon, and Valeene before they were discovered and forced to run for the river.  Hines and a few of his men escaped into Kentucky, the others were captured.  (By John Osborne)

The Army of Northern Virginia moved north towards Pennsylvania behind a solid Confederate cavalry screen.  In one  of several Union attempts to penetrate this screen, a sharp cavalry battle was fought near the village of Aldie in Loudoun County, Virginia.  General Judson Kilpatrick' s Union cavalry clashed with Confederate Colonel Thomas J. Munford and his men in a four hour late afternoon fight. Munford withdrew but the cavalry screen held.  Union losses were around three hundred dead and wounded, while Munford had just over a hundred killed and injured.  (By John Osborne)
