JEFFERSON, Md. (WJZ) — A team of bomb technicians from the Office of the State Fire Marshal safely disposed of a Civil War-era ordnance Monday evening after it was discovered by a Frederick County homeowner.

A homeowner on Glen Hill Court in Jefferson contacted the fire marshal’s office after another family said the cannonball was live. The family gave it to the homeowner after finding it near the Monocacy Battlefield.

The cannon call was safely removed and taken to the Beaver Creek Quarry in Hagerstown for an emergency disposal.

Maryland has a long history of military testing — most notably at Aberdeen Proving Ground in Harford County. Unexploded military ordnance sometimes will make its way to the surface.

Even Civil Ware-era devices can pose a threat.

“If you should uncover or are unsure if an unidentified object may be military ordnance, be safe rather than sorry. Stay away and call 911,” stated State Fire Marshal Brian S. Geraci “Marylanders need to be mindful that military ordnance, even vintage artifacts from previous conflicts, have the potential to explode.”
