When Captain William H. Boyd's 43 man company of First New York Cavalry probed the Confederate advance near Greencastle, they lost one man killed in the brief fight. Corporal William H. Rihl, a twenty-year old Philadelphia gardener, was killed instantly with a rifle shot to the head, the first Union soldier to die in Pennsylvania.  Confederates buried Rihl in a shallow grave but local citizens removed his body for a proper burial in the Lutheran Churchyard. In 1886, a memorial was dedicated where he fell and his remains were returned to rest there. (By John Osborne) 

The rapid Confederate advance reached Greencastle in Franklin County around noon.  Soon after, a forty-three man company of First New York Cavalry led by Captain William H. Boyd appeared and made a small, bold charge to determine the strength of the enemy losing one man, Corporal William H. Rihl, killed and one man wounded.  Boyd and his men had been escorting the retreating Winchester garrison and during the invasion occupied themselves with harassing Lee's advance and gathering intelligence.  (By John Osborne)

The first two divisions of General Richard Ewell's Second Corps of the Army of Northern Virginia, commanded by Generals Early and Rodes crossed the Potomac into Maryland on Saturday and Sunday. The other division followed on Monday under General Edward Johnson. Early and Rodes linked up with the cavalry division of General A.G. Jenkins at Hagerstown early that same day and then marched north to begin in earnest the invasion of Pennsylvania, reaching Greencastle in Franklin County by mid-day.  (By John Osborne) 

Confederate cavalry under General Albert Jenkins advanced into Pennsylvania chasing the garrison from Winchester.  He had occupied Chambersburg during the night before and soon set about burning the nearby railroad bridge of the Cumberland Valley Railroad at Scotland. Jenkins pulled back to Hagerstown, Maryland to rejoin the Army of Northern Virginia and marched back into Pennsylvania with the main invasion.  (By John Osborne)

Just before midnight, Confederate cavalrymen of General Jenkins' division entered Chambersburg, Pennsylvania. Making their headquarters at the Montgomery Hotel in the town, they remained for two nights, confiscating weapons, gathering supplies paid for in Confederate script, and rounding up African-Americans for return to the South, before making a hasty withdrawal as Union troops advanced from Harrisburg.  (By John Osborne)
