HNoMS Svenner was hit by two torpedoes fired from one of two German T-boats, either Jaguar or Moewe of 5th T Flotilla operating out of Le Havre, that managed to get within firing range. Svenner was the only Allied ship to be sunk by German naval activity on the morning of 6 June. She was struck amidships, exploded, broke in two and sank very quickly. 32 Norwegian and one British crew were killed, 185 (15 wounded) were rescued from the crew of 219. (The book D-Day by Stephen Ambrose contains a photograph, in the 16 pages of photographs after page 160, of the moment that the Svenner blew up.)
The anchor from Svenner was recovered in 2003 and now forms 'The Svenner Memorial' at Sword Beach. The memorial can be found approximately 100 yards on the sea-side of the coast road at Hermanville-sur-Mer, Normandy, France.
