West Manchester Township, York County, Pennsylvania

In 1799, West Manchester Township was formed from part of the western portions of Manchester Township. Farming, weaving, and milling were among the major occupations.

During the 1863 Gettysburg Campaign of the American Civil War, the township was a main thoroughfare for two invading forces of the Confederate Army. On June 28, 1863, Major General Jubal A. Early's division marched east–west through the township en route to seize York. On July 1, J.E.B. Stuart's cavalry rode north–south through the township following the Battle of Hanover on their way to Dover. West Manchester Township farmers and residents lost horses and mules to the Confederates.

The Samuel Stoner Homestead was added to the National Register of Historic Places in 1976.[5]
