every day, running on her schnorkel, surfacing for just one hour per day at 23:00, later reduced to 15 minutes. Colin Three weeks into her voyage, Jebsen saw a target he could not refuse. The Colin, formerly an Italian freighter taken over by American authorities and registered in Panama, was slowly steaming unescorted in the North Atlantic following engine failure. Three torpedoes sank her before U-859 went on her way southwards. The boat's voyage continued smoothly for the next two months, and she rounded the Cape of Good Hope and entered the Indian Ocean without further trouble. On 5 July she was spotted by a Lockheed Ventura aircraft, which swooped down on the boat only to be brought down by the anti-aircraft guns. There were no survivors from the aircraft's crew. One rating of U-859 was killed and one officer seriously injured. (Other sources say the attacking plane was a Catalina anti-submarine-plane). John Barry Her second victim was her most famous, and became one of the most famous treasure shipwrecks of the Twentieth Century. The unescorted Liberty ship was transporting a cargo of 3 million silver one-riyal coins from Aden to Ras Tanura in the Persian Gulf as part of an American government agreement with the Saudi royal family; the silver coins had been minted in America for Saudi monarch King Abdul Aziz Al-Saud and were stacked in huge boxes in the hold, and went down with the ship when she was torpedoed at , about south of the entrance to the Arabian Sea. A massive salvage operation in 1994 succeeded in retrieving many of the lost coins. Troilus Three days later another unescorted merchantman, the British Troilus was also sunk, with six hands drowned. Fate On 23 September 1944 U-859 was running on the surface, within of Penang and the end of her voyage, when she was intercepted in the Malacca Straits by the British submarine , which had been forewarned of her arrival date and route by decrypted German signals. In difficult conditions with a heavy swell running and a second U-boat thought to be lurking, Trenchants commander Arthur Hezlet carried out a snap attack using his stern torpedo tubes, hitting U-859 amidships. The U-boat sank immediately in of water with several compartments flooded, and 47 men drowned, including her commander. Twenty of the crew did manage to escape however, opening the hatch in the relatively shallow sea
