The German torpedo boat T26 was one of fifteen Type 39 torpedo boats built for the Kriegsmarine during World War II. Completed in early 1943, the boat was transferred to France in August. T26 helped to lay a minefield in the English Channel the following month, and later escorted a blockade runner through the Bay of Biscay. She participated in the Battle of Sept-Îles in October and was sunk two months later by a British light cruiser during the Battle of the Bay of Biscay.

HMS Limbourne (L57) was a Hunt-class escort destroyer, operated by the Royal Navy. She was sunk in action, off German-occupied Guernsey, on 23 October 1943.
