In 1940, the ship was decommissioned for passenger service and was acquired by the Italian Navy as a troopship for the war effort. At 2:00am on 19 August 1941, the Neptunia sailed from Naples in convoy with the Marco Polo, Esperia, and her sister ship, Oceania and naval escort ships bound for Tripoli.[2] Whilst on the approaches to Tripoli, at about 10:20am on 20 August the Esperia was torpedoed three times by the British submarine HMS Unique. The ship sank very quickly, whilst the other ship increased their speed to try and reach the safety as quickly as possible. Despite the speed with which the Esperia sank, over 1,100 people were rescued. The convoy reached Tripoli, entering the port at 12:30pm. On 18 September 1941 the Neptunia was sunk by the submarine HMS Upholder.[1]
