Inscription.
By the summer of 1861, the Union recognized Darnestown as an ideal location for establishing a major division headquarters. The town was strategically situated at the intersection of roads leading to the Chesapeake and Ohio Canal and to Washington, D. C., and it was not far from the fords of the Potomac River.

President Lincoln and his generals feared that if Confederate troops crossed the Potomac River into Montgomery County, they might invade the Nation's capital from the north.

As a result of its location, the rural village of Darnestown and its citizens saw Union and Confederate movements throughout the Civil War.

Union Troops at Darnestown
Federal forces established a main line of defense and headquarters for three brigades of General McClellan's Army of the Potomac, under the command of Major General Nathaniel P. Banks. The patience, loyalties, and resources of Darnestown were soon tested with the coming of an entire Union division. The encampment lasted from August to December 1861. The 18,000 Union troops that doubled the total population of Montgomery County were camped on farmland around Darnestown at Seneca Creek, and in smaller encampments from Harpers Ferry to Muddy Branch.
