U-513 attacked and sank SS
Lord Strathcona and SS
Saganaga. Twenty-nine sailors aboard
Saganaga died. Right after the attack,
U-513 left the area following
Evelyn B again. On 2 November at 3 a.m., the waters off Bell Island saw a second attack, this time executed by . Commanded by Friedrich Wissmann, the U-boat was at the southern end of Bell Island in an area known as "The Tickle," also known as Wabana Anchorage. Over the course of an hour, she fired a
torpedo at the 3,000-
gross register ton Anna T. The torpedo missed and went under SS
Flydingdale which then exploded towards the loading dock. This explosion startled many in Bell Island. Wissman fired twice more. The torpedoes went straight towards SS
Rose Castle, and the ship immediately sank, killing twenty-eight men. The
Free French ship
Paris Lyon Marseille 27 was also attacked, and right after being struck, sank with 12 of her crew aboard.
U-518 then escaped even though there were two
patrol vessels nearby. The whole attack lasted ten minutes. The Governor of Newfoundland,
Sir Humphrey Walwyn, was angered by these sinkings. Upon his return to St. John's, he called the Chief of Staff, Captain F. L. Houghton, and said "It was madness to let ships lie unprotected." ==Aftermath==
