German submarine U-844 was a German Type IXC/40 U-boat of the Kriegsmarine, built for service during the Second World War. An extremely short-lived boat, U-844 served just ten days on her only patrol and was sunk with two other boats whilst preparing for a failed attack on a well-defended convoy within range of allied air support.
Built by the large AG Weser shipyards in Bremen, U-844 was rapidly completed and readied for service, her entire building program taking just under a year. Given to Oblt.z.S. Günther Möller, she passed her initial working-up and training schedule well, and was despatched to her first patrol in the Atlantic Ocean in the first week of October 1943 to try to stem the terrible losses being incurred by U-boats at this time.
Ten days after her departure whilst she sailed south of Iceland she received orders to attach herself to U-470 and U-964 and to proceed southwards to attack Convoy ON 206 in the North Atlantic. The boats had to travel on the surface to have any hope of reaching their target, and it was this which caused disaster, as the three submarines were spotted in broad daylight by a Consolidated Liberator aircraft, which rapidly called allies in the form of more Liberators from 59 Squadron and 86 Squadron Royal Air Force amongst other forces.
During the day long battle which followed, the anti-aircraft weapons of the boats were brought into use, downing two Liberators and killing a number of crewmen. It was not however enough to stave off the inevitable, and one by one the boats were separated and sunk, having been prevented from diving by constant attention from Allied aircraft. U-844 was eventually lost to a direct hit from a bomb dropped by a Liberator, the boat blowing to pieces and killing all 53 of her crew.
