Though not a biography in the strictest sense, I just finished Indianapolis The True Story of the Worst Sea Disaster in U.S. Naval History and the Fifty-Year fight to Exonerate an Innocent Man. One of the best damn books I've read in a while. Don't let Robert Shaw's monologue in JAWS be all you know about the U.S.S. Indianapolis.
