Carpathia was used to transfer American troops to Europe during the First World War. Among them was Frank Buckles, who became the last surviving American veteran of the war. Carpathia departed Liverpool in convoy on 15 July 1918. Shortly after 00:00 on 17 July she was torpedoed in the Celtic Sea by German submarine U-55. Of two torpedoes fired at the ship, one impacted the port side while the other penetrated the engine room, killing two firemen and three trimmers. As Carpathia began to sink by the bow, Captain William Prothero gave the orders to abandon ship. All 57 passengers (36 saloon class and 21 steerage) and 218 surviving crew members boarded the lifeboats as the Carpathia sank. U-55 surfaced and fired a third torpedo into the ship and was approaching the lifeboats when the Azalea-class sloop HMS Snowdrop arrived on the scene and drove away the submarine with gunfire then picked up the survivors from the Carpathia. Carpathia sank at 12:40. Thanks mrawesomeface123 for editing thi
