At last count, nearly 2,400 people can claim that their lives were saved by a U.S. submarine during World War II. Of that number, 523 Allied aviators could claim that distinction after crashing their aircraft into the sea and being saved by a submarine operating in the "Lifeguard League." The remaining number were a collection of other military and civilian personnel, each with a story to tell and now able to tell their grand-children. Some of those rescued went on to retire as senior military officers including U.S. Navy Admirals, some back to missionary work, some to manage large companies in later years, some to philanthropic endeavors to pay everyone back for saving their lives. Appendix A is an intensely-researched index of nearly 2,200 names of those saved.
