The aerial photograph of the modern York Flour Mills, Inc. is courtesy of Microsoft Virtual Earth, and shows the location of one of the old P.A. & S. Small mills nestled between the railroad and the Codorus Creek. In 1863, the railroad line was the Northern Central's tracks that led from Baltimore to Harrisburg, and Confederate troops camped in and around the mill yard. Armed guards made sure no one broke into the mill.
Earlier in the war, thousands of Union soldiers crossed by the landmark mill on troop trains headed south to join what became the Army of the Potomac.
