Operation Wikinger. Without informing the Luftwaffe, 6 German destroyers sortie into the North Sea through a narrow lane between minefields, to disrupt scouting of German warships by British fishing boats.

At 7.45 PM, destroyer Z1 Leberecht Maas is hit by two bombs and sinks (282 lives lost, 60 survivors). Destroyer Z3 Max Schultz takes evasive action, hits a mine and sinks with her crew of 308. http://www.german-navy.de/kriegsmarine/articles/feature4.html
