Jan Lettens02/01/2013On July 17th 1944, I-166, a KD5 type submarine, was torpedoed and sunk by the British submarine HMS Telemachus in the Strait of Malacca.

One torpedo hits the stern of I-166, causing a violent explosion. The submarine sinks in 130 feet of water.

88 sailors were killed in the explosion. Ten others, including Lt. Suwa and the navigating officer, are blown overboard. Seven hours later they are picked up by Malayan fishermen
