Ship History
Built by by California Shipbuilding Corporation, Wilmington, California as EC2 class "Liberty Ship". Laid down March 10, 1943 as liberty ship SS Benjamin N. Cardozo (MCE hull 739). Launched April 5, 1943. Transferred to the U. S. Navy (USN) on April 19, 1943 and renamed USS Serpens (AK-97). Commissioned May 28, 1943 at San Diego. Assigned to Captain Magnus J. Johnson, USCGR and manned by crew from the U. S. Coast Guard (USCG).

Sinking History
On January 29, 1945 Serpens was anchored off Lunga Point on Guadalcanal and was being loaded with depth charges. Late in the evening, the ship suddenly exploded. Aboard, 193 U. S. Coast Guard (USCG) crew, 56 U. S. Army stevedores and a Public Health Service physician were killed in the blast. The force of the explosion was so great that it also killed a U.S. Army soldier ashore. Only two sailors aboard survived the incident. At the time of the explosion, the commanding oficer and enlisted men were ashore. The cause of the explosion was never determined. The sinking of the Serpens was the largest single disaster ever suffered by the U. S. Coast Guard (USCG).

Robert Brock adds:
"A ship anchored off Lunga Point on Guadalcanal exploded one night and covered the beach area and inland for several meters with debris. An article was in 'Ripleys Believe-it-or not' several years ago in which it stated that one man survived the blast and was blown through a porthole. I helped recover bodies the next day. Many of the casualties were stevedores from Fiji."

During 1944, this shipwreck was first identified by Ewan Stevenson. The bow is upside down off Lunga Point on Guadalcanal.
