On January 31, 1917, Germany, determined to win its war of attrition against the Allies, announced it would resume unrestricted warfare in war-zone waters. Three days later, the United States broke diplomatic relations with Germany, and just hours after that the American ship Housatonic was sunk by a German U-boat.
U-Boat 110 destroyed ten vessels before it was sunk by the Royal Navy during July 1918. The Royal Navy managed to surface the sunken u-boat and were planning to return her to service. The u-boat which had a crew of around 41 poeople only had nine survivors when it was defeated in battle. The vessel went down off the coast of Hartlepool in the north east of England.
