A fierce WW2 battle at sea, unreported for more than 60 years, is revealed at the bottom of the Gulf of Thailand. There lies the US submarine Lagarto and the remains of her 86 crewmen, entombed 8,000 miles from the tiny Wisconsin town where the sub was built. This is the powerful story of the last battle of Lagarto and her crew, the families left behind with no graves to mourn, bodies to bury, and the mystery of why no one escaped from the sinking sub.
