Researchers at a Revolutionary War battlefield in New Jersey have unearthed a mass grave holding the remains of around a dozen Hessian mercenaries who died during the Battle of Red Bank in 1777.
Volunteer diggers also unearthed a number of treasures, including weapons and a rare 1776 King George III gold guinea coin.
The burial site was discovered on June 26 when a volunteer amateur archaeologist uncovered a human femur (thigh bone) during the excavation of a defensive trench at Fort Mercer, which is part of Red Bank Battlefield Park(opens in new tab) in Gloucester County, southern New Jersey.
