A remarkable set of six photographs, showing the Hartlepool steamship Longscar, being stopped and sunk by the German submarine UC-21, on February 14th, 1917. The Longscar was a 2,700 ton steamship built at the William Gray shipyard in West Hartlepool in 1903 for Thomas W. Willis, a well-known West Hartlepool shipowner. She was stopped and sunk in the Bay of Biscay while on passage from Nantes to Bilbao in ballast, fortunately with no casualties.
The photographs, from an album compiled by one of the U-boat's crew, have kindly been shared with this project by Mr. Martin Spaldin.
