On a dark Mediterranean night in 1943, a submariner's indiscretion saved his own life as well as the lives of his crewmates.
National stereotyping and smoking: Two habits now viewed with disdain. In fact, if you were to flaunt them openly, you would be seen as a pariah to many. Yet as a submarine officer in HMS Seraph during World War II, I saw these two behaviors save 65 men from a horrible death.
