Learning about discovered defense against British warships in Delaware River
Cheval-de-frise found 30 miles north of Philadelphia undetected for 240 years
Airdate: January 27, 2022
Chevaux-de-frise were spiked pole-like objects submerged in the Delaware River during the Revolutionary War to obstruct British vessels from moving on Philadelphia.
It was thought that all the Chevaux-de-frise was located south of the city to keep the British from sailing north from the Delaware Bay. However, in 2012, a local yacht club discovered a cheval-de-frix near Bristol in Buck County — 30 miles north of Philadelphia.
It had been hidden underwater for almost 240 years, in spite of its large size — almost 30 feet long and 13 and-a-half inches in diameter.
