At 20.38 hours on 24 Aug, 1940, the HMS Penzance (L 28) (Cdr Allan John Wavish +), escorting the convoy SC-1, was hit by one torpedo from U-37 and sank in a few minutes southwest of Iceland. When the depth charges of the sinking sloop exploded the U-boat was slightly damaged by the detonations. Seven survivors were picked up by a merchant from the convoy, the Blairmore, but she was also sunk by U-37 during the night. The survivors were rescued by the Swedish merchant Eknaren (Master Erik Kallstrom) and landed at Baltimore.
