German submarine U-875 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. 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
