Join Janet Johnson, State Museum Curator of Archaeology to learn about an unusual discovery from the Delaware River.
Cleanup efforts by a local yacht club following Hurricane Sandy in 2012, led to the discovery of a cheval-de-frise near Bristol, Bucks County, Pennsylvania. The Pennsylvania Committee of Safety authorized the use of Chevaux-de-frise (plural), a submerged defensive obstruction, during the Revolutionary War (1775-1783) as protection against British troops advancing on Philadelphia. Historic maps indicate their placement in the Delaware River near Fort Mifflin, south of the city. However, this single cheval-de-frise was recovered nearly thirty miles north of Philadelphia where it lay hidden for almost 240 years. It’s massive size, just under 30 feet long, and 13.6 inches in diameter with a large iron spike is an important story of our past and our efforts to defend the colony. Curator Janet Johnson will discuss her research of this significant artifact and the preservation of this unique discovery.
