Doyle, you might want to drop Chambersburg. See below fro Wickipedia. Stan
"During the American Civil War on October 11, 1862, Confederate Maj. Gen. J.E.B. Stuart and his cavalrymen looted Chambersburg during a raid into the North. During the early days of the 1863 Gettysburg Campaign, a Virginia cavalry brigade under Brig. Gen. Albert G. Jenkins occupied the town and burned several warehouses and Cumberland Valley Railroad structures and a nearby bridge. Later, much of the Army of Northern Virginia passed through Chambersburg en route to Carlisle and Gettysburg, and Robert E. Lee established his headquarters at a nearby farm.

The following year, Chambersburg was invaded for a third time, as cavalry dispatched from the Shenandoah Valley by Jubal Early arrived. On July 30, 1864, a large portion of the town was burned down under orders from Brig. Gen. John McCausland for failing to provide a ransom of $500,000 in US currency, or $100,000 in gold."

It does appear that the first time only military targets were hit. Lee apparently din't burn anything, and the last time they didn't pay the ransome. Stan
