During World War II, “Loose Lips Sink Ships” was a familiar slogan on both sides of the Atlantic at a time when German U-boats (U for unterwasserboot, submarine) were wreaking a deadly toll on cargo vessels transporting Allied supplies from North America to the beleaguered British Isles. Loose lips, of course, referred to the mention of shipping movements, destinations, cargoes or just about anything else to anyone not having a “need to know,” even apparently harmless comments to a friend like “Jack is going away on Thursday, and won’t be back for three or four weeks.” Overhearing that, a skilled enemy agent might tie it together with the knowledge that Jack is a merchant ship sailor; with a few more pieces of overheard chitchat, Jack might never return.
