Finished O'Kane's "Wahoo" and "Clear the Bridge". Both excellent books.
Just started "War in the Boats" by William Ruhe. So far so good. His description of life on the S-boats in 1942 is pretty incredible.
A over cautious captain, mechanical difficulties, the heat, sleeping in bunks near vents where the batteries vent their gases during the charge, not to mention the 1/2 inch puddle of sweat left over from the previous occupant, wondering if the boat will hold to together at the "deep submergence" of 135 feet, and cockroaches.
