The game: Kriegsmarine by WDS
The scenario: December 7, 1939: The Night of December 6/7, the Germans ran a minelaying mission off the Hainsborough lightship with three Z-Class destroyers. One was turned back with mechanical difficulty, but the other two continued the mission.. After their mines were dropped, they were headed eastward when they spotted two British destroyers on a parallel course. After a short action, the Germans disengaged and headed home, but not before torpedoing and seriously damaging HMS Jersey.
A very small engagement, totally worth it. Played as the Germans.
