Captain Henry D. Landis' First Philadelphia Artillery was typical of the emergency units enlisted in the state during the Confederate invasion of Pennsylvania, although distinguished by its service and personnel.  Mustered into the Army just six days before it arrived to defend Carlisle against Confederate cavalry, it contained throughout its ranks the young heirs of some of the richest and influential families in Philadelphia. The 108-man battery engaged in counter fire from the town square during the engagement. The unit mustered out on July 30, 1863. (By John Osborne)   

After finding Carlisle garrisoned and resisting his late night attack, Confederate cavalry General J.E.B. Stuart received orders after midnight to move towards Gettysburg.  He left Carlisle, still suffering from the effects of his artillery bombardment, in the early hours of the morning and marched his exhausted and hungry troops without halt, arriving at Mount Holly and then York Springs in mid-morning.  He finally rested his command at Heidlersburg, ten miles north of Gettysburg.  (By John Osborne)  

With the Union garrison of Carlisle resisting his late evening efforts to take the town, Confederate General Stuart sent Colonel Williams Wickham and his 4th Virginia to burn the Carlisle Army Barracks on the edge of town. The Virginians destroyed seven of the eleven buildings on the post and also destroyed the town's gas works in a spectacular fire.  Stuart then withdrew after midnight towards Gettysburg, reaching Boilings Springs by morning.  (By John Osborne) 

After the departure of the last Confederate troops just after dawn, Union troops began to arrived in Carlisle through the day till by evening, the borough contained two brigades of militia infantry, a unit of New York Volunteer Cavalry, and a small artillery battery.  In overall command of the barely trained Pennsylvania and New York militiamen was General William "Baldy" Smith.  The town welcomed them all with enthusiastic hospitality in the town square.  (By John Osborne)
