Diver finds long-lost World War II submarine after 25 years of searching: "The hardest mission I have ever undertaken"

A veteran Greek diver specializing in locating sunken ships announced Wednesday that he has found a British submarine that disappeared during a World War II mission in 1942.

Kostas Thoctarides told state news agency ANA his team had located the wreck of HMS Triumph at a depth of 670 feet at an undisclosed location in the Aegean Sea.

The search for the submarine began in 1998 and was "the hardest mission I have ever undertaken in my life," Thoctarides said in a Facebook post. He also posted video and images of the shipwreck, showing the wooden steering wheel, compass and cannon.
