Woodbury, founded in 1683 by Henry Wood, is the oldest municipality in the county. The municipality of National Park hosts the site of the Revolutionary War Battle of Red Bank where Fort Mercer once stood. It is now the site of Red Bank Battlefield Park and the remains of HMS Augusta laid there until they were moved and subsequently re-sunk in Gloucester City on their way to Philadelphia. During the colonial era, Gloucester County's main economic activity was agriculture. Woodbury was the site of the county courthouse, the county jail, a Quaker meeting house (still in existence), and an inn (on the current location of Woodbury Crossings). Because of the county's many creeks leading to the Delaware River and the Atlantic Ocean, smuggling was very common.
