First of all, thanks for the updates. I've modified my original post to reflect the additions.
Second, I have finished reading
Batfish, the Champion "Submarine-Killer" Submarine of World War II by Hughston E. Lowder and Jack Scott. This was a wonderful, wonderful book. Not too long, not too short. It doesn't repeat a bunch of the "whys" and "how-comes" that so many books do. This book is about the Batfish, period. The last chapter is really great too, which talks of how the boat was acquired by Muskogee to become a museum.
When I got to page 243 (the book has 244 pages) I read this paragraph:
"She is perhaps the only submarine in the world one can view almost from the bottom up. And with her keel four feet into the moist sand, electrolysis works like acid upon her bottom. Unless lifted onto a drydock, she'll be rusted through in twenty years or so."After reading that paragraph, I immediately flipped back to the front pages to search for a copyright date....1980!
