You are all welcome. You, (Glock-A-Roo) can take credit for drawing our attention to it. I'd actually read McVay's account a while back, but I learned a whole lot more yesterday. Note that extensive previews of many of the books on the Indianapolis are readable at the links I gave. A lot of information absent in early accounts came to light in the 1990s as a result of declassification, private reinvestigation of documents, and extensive interviews of survivors and their rescuers. Here are three more accounts readable online:

• Section on Indianapolis from "Bitter Victory" - click to expand
  
• Sunk, by the author of "In Harm's Way"
  
• Charles B. McVay III: Accountability
