The TSS Cambria was a twin screw passenger steamship constructed in 1897 by William Denny and Brothers of Dumbarton for the London and North Western Railway. Designed to compete with the City of Dublin Steam Packet Company's high-speed vessels, she was built to enhance the railway company's maritime services, especially on routes such as Holyhead to Dublin. The vessel's twin screw configuration provided stability and efficiency, though specific dimensions and tonnage are not detailed in the provided source. Throughout her operational life, the Cambria served primarily as a passenger vessel. However, her role extended significantly during wartime. In 1914, she was requisitioned by the Admiralty and converted into an Armed Boarding Steamer, reflecting her versatility and importance. By August 1915, she had been repurposed as a hospital ship, contributing to the war effort by providing medical services. After the war, the vessel was renamed TSS Arvonia in 1919. Her service was again requisitioned during the Irish Civil War, notably in July 1922 when she was used as a troopship by the Irish Free State. During the Battle of Limerick, the Arvonia transported troops and equipment into Limerick Docks, playing a strategic role in the conflict. She was also fitted in Dublin to carry approximately 400 troops under Colonel-Commandant Christopher (Kit) O'Malley, with operations involving landing troops in Westport, County Mayo, and executing surprise landings at Passage West near Spike Island in August 1922. Further, the Arvonia was involved in prisoner transport, notably carrying prisoners from Limerick Prison, including Cornelius McNamara, to internment camps in September 1922. Her final significant act was on 17 December 1922, when Captain Henry Robinson and remaining British troops evacuated Ireland aboard her, marking the end of her service in the conflict. The vessel was scrapped in 1925, ending her maritime career. Overall, the TSS Cambria, later Arvonia, was a vessel of considerable historical significance, serving both as a passenger liner and an integral part of military operations during a turbulent period in Irish history.
