History
During the Gettysburg Campaign in the American Civil War, the Battle of Fairfield played an important role in securing the Fairfield pass and the Hagerstown Road, enabling Robert E. Lee's Army of Northern Virginia to retreat through Fairfield towards the Potomac River. The actual fighting near Fairfield was between elements of the 6th United States Cavalry under Major Samuel Starr, and elements of General "Grumble" Jones' Brigade of Virginia Cavalry. The Union casualties were treated in the town of Fairfield, specifically in the homes of Mrs. Sarah Amanda Blythe, Rufus Christian Swope, and in what is now St. John's Lutheran Church.
