My ancestor fought with the 140th Pennsylvania volunteer Infantry Regiment which mustered into service in the summer of 1862. So it’s not just that Pennsylvania sent so many men to war, but also how quickly those units were formed. The 140th was in training into the fall and missed Antietam and Fredericksburg and didn’t see real action until spring of 1863.
