Silent War (board game).

[Kapitänleutnant Erwin]

To call Silent War a game is akin to calling the priesthood a hobby. Prepare to undergo some serious indoctrination--this game really tries to replicate every aspect of the entire war. There are provisions for aircraft attacks, surface gun attacks, repairs, circular running torpedoes, special missions, Ultra intercepts, wolfpacks... just about any situation you can imagine that is historically based.
