This old grist mill on the banks of the Big Conewago Creek in extreme southern Washington Township, York County, Pennsylvania, has a long and storied history, including playing a role in feeding Confederate troops in the Gettysburg Campaign during the American Civil War. Known for many years as the "Eisenhart Mill" for a post-war owner, during the War Between the States, the mill was owned and operated by a miller named Emanuel Butt.
On June 28, 1863, Confederate troops of the veteran division of Major General Jubal A. Early marched through Adams County to East Berlin and subsequently camped in nearby York County at the hamlet of Big Mount. Along the way, dozens of residents were victimized by foraging patrols which were seeking supplies, food, and, most of all, fresh horses and mules.
