Fifteen days. That is how close U-183 came to surviving the Second World War. On 23 April 1945, as Allied forces closed in on Berlin and the Third Reich crumbled, a torpedo from the American submarine USS Besugo struck the German boat in the Java Sea, sending her to the bottom with forty-seven of her forty-eight crew. The war she had been built to fight was already lost. But U-183 had never fought the war most U-boats knew -- the freezing convoy battles of the North Atlantic, the cat-and-mouse games with British destroyers. Her war had played out in the tropics, in waters most Germans could barely find on a map, operating from a Japanese-held port on the other side of the world.

Commissioned on 1 April 1942, U-183 was a Type IXC/40, one of the Kriegsmarine's long-range workhorses. At 76.76 meters long with a surface range of nearly 14,000 nautical miles, these boats were designed to reach targets that the smaller Type VIIs could not. She carried twenty-t...

In the summer of 1943, Germany launched one of the war's more audacious naval operations: sending U-boats around the Cape of Good Hope to operate from Japanese bases in Southeast Asia. These were the Monsun boats -- named for the monsoon winds they would encounter -- and U-183 sa...

For nearly two years, U-183 operated from Penang and conducted six war patrols in the Indian Ocean. The hunting was sparser than the Atlantic -- fewer convoys, longer transits, vast empty stretches of water. In March 1944, she scored her most notable attack, torpedoing the Britis...

By April 1945, the war in Europe had weeks left. Hitler was in his bunker. The Western Allies had crossed the Rhine. The Soviet army was closing on Berlin. None of this mattered to U-183, operating thousands of miles away in the Java Sea with whatever orders still reached her thr...

For decades, U-183 lay undisturbed on the seabed. Then, in November 2013, divers located a wreck believed to be either U-183 or another vessel in the area. The discovery reportedly revealed seventeen skeletons still inside the hull, a reminder that these wrecks are not just artif...
