The Cumberland Valley played a significant role in America’s Civil War. When the war began, local residents rushed to join the Union army. Area families made deep sacrifices for the war effort culminating with the Confederate invasion of PA in summer 1863. Southern troops passed through the valley, occupied communities, skirmished with militia and sometimes even shelled towns.
