April of 1945, the Japanese military command sent its prize battleship on an impossible kamikaze mission; to defeat a large US fleet off the coast of Japan. Her name was the Yamato and she was the largest and most technologically advanced battleship in history. With guns of awesome caliber, massive armour, she was considered to be virtually unsinkable. Yet she would be sunk, in just four hours, during one of the last naval battles of World War II. This is the story of the Battleship Yamato, its creation as the flagship of Japanese naval power, its part in the battle of Midway, up to its last suicide sortie and how its recent discovery has shed light on its final moments. In 1999 a Japanese salvage crew set off on a multi-million dollar mission to find the final resting place of the pride of Japan. Three hundred and fifty meters down, the Yamato lay largely intact on the floor of the South China Sea. Some of the first ever pictures of the remains of history's largest battleship offer not only a solemn tribute to the brave sailors who died for their country, but also a clue to a mystery... what actually happened in the final moments of the Yamato?
