The Koh Tao wrecks
Tottori Maru
The Gulf of Siam was invaded by patrol SubSoWesPac to the end of the Second World War. The interior of the Gulf has long been marked off limits for submarine patrols because the military thought dotted with mines. But in March 1945 patrols in the Gulf were taken over by the British submarine TRADEWIND. In April, the HARDHEAD covered the approaches of Bangkok in May 1945, the submarine Baya, LAGARTO and HAMMERHEAD entered the Gulf and found targets. Working as a team with the Baya for attacks on convoys, the LAGARTO was lost and Baya was damaged by cons more important measures than expected. However the HAMMERHEAD sank a small freighter off the Malaysian coast on May 6, and in the same area trickled TOTTORI MARU, a passenger cargo 5,973 tons May 15 After that, the traffic between Siam and Singapore has been "reduced to almost nothing." (excerpt from the book "UNITED STATES SUBMARINE OPERATIONS IN WORLD WAR II" by Theodore Roscoe 1949). The wreck lies on its starboard side in 58 meters of water. The highest part of the wreck is 40 meters with a length of 150m and a tonnage of 5-7000 tons. The ship is damaged starboard side environment. More extensive research is required but is suspected to share the coordinates identified by the submarine Hammerhead it could well be the Tottori Maru, a "hell ship" used to transport prisoners of war allies
