The Benwood was built in England in 1910 and later operated as a merchant freighter. During World War II, the vessel carried cargo along the U.S. East Coast.
On the night of April 9, 1942, Benwood was traveling from Tampa to Norfolk carrying phosphate rock. With German U-boats believed to be operating in the area, the ship was running without external lights. The southbound Robert C. Tuttle was doing the same. The two vessels collided, crushing Benwood’s bow. The crew abandoned ship, and Benwood was later declared a total loss.
Salvage operations continued into the 1950s. NOAA states that the wreck is believed to have been intentionally blown up to reduce its danger to navigation, and the U.S. Army also used it for aerial target practice after World War II. These events help explain the scattered wreckage divers see today.
