I've been working on a story for more than fifty years. I've started and stopped dozens of times but this time I am going to end it but with a conclusion that I can only guess at. I heard the tale when I was about 15. It was told in bits and pieces over a period of ten days or so. After the trip ended I never saw the tale teller again. There was precious little doubt in my mind that I was hearing a true tale as it unfolded; some things you just cannot fake. Absolute horror is one of them. I wrote the story in about 1960 and told a few friends that it was true. Several friends said "BS." I tried to research the events while I was in college but details were sketchy and, as I learned about 5 years ago, absolutely WRONG. With the information available today I am absolutely convinced that my tale is true even though, at this late date, I have no way to prove it. I must call it fiction. My question is, can I add historical data before or after the story to lend weight to my tale? The historical event is the sinking of the U-166 in the Gulf of Mexico in 1942. All hands died--except one.
