HMS Ocean (1898): Lost in the Dardanelles Trying to Rescue Another Sinking Battleship

The First Big Ship Built at Devonport
HMS Ocean was laid down at Devonport Dockyard on 15 December 1897, the first large armoured warship ever built at that yard, launched on 5 July 1898 by Princess Louise, Marchioness of Lorne, and commissioned on 20 February 1900 under Captain Assheton Curzon-Howe, a Canopus-class battleship, one of six vessels built deliberately smaller, lighter and faster than earlier British battleships while retaining the same heavy main armament, a design specifically intended for service in East Asia.
China, Typhoons and a Changing Alliance
HMS Ocean served with the Mediterranean Fleet immediately after commissioning, departing Devonport on 13 March 1900 and reaching Gibraltar four days later, before transferring to the China Station in 1901 in response to the Boxer Uprising. She visited Port Lazaref on the Korean peninsula in October 1902, but suffered typhoon damage that required extensive repairs through 1903. Her entire East Asian deployment was rendered largely redundant by the Anglo-Japanese Alliance of 1902, and she and three sister ships departed Hong Kong on 7 June 1905, arriving back at Plymouth that August.
A Long Peacetime Career
HMS Ocean spent the years before the First World War moving through a series of fairly routine assignments: reserve at Chatham from 1905 to 1906, service with the Channel Fleet from 1906 to 1908, a further Mediterranean Fleet commission with fire control upgrades from 1908 to 1910, the Home Fleet's 4th Division from 1910 to 1913, and finally the 3rd Fleet at Pembroke Dock in Wales from 1913 to 1914, a genuinely long and unremarkable peacetime career for a battleship whose most consequential chapter still lay ahead.
Bombarding Al-Faw
HMS Ocean joined the 8th Battle Squadron on 14 August 1914 and was detached to Queenstown, Ireland, a week later, before deploying to the Persian Gulf that October to serve as flagship supporting operations against Basra. On 6 November she began the bombardment of Al-Faw, with a subsequent landing party capturing the fortress there without meeting any resistance, and by December ground forces had reached Al-Qurnah, prompting her reassignment elsewhere.
Defending Suez
HMS Ocean arrived at Suez on 29 December 1914 to help defend the vital canal, and on 3 and 4 February 1915, alongside the armed merchant cruiser Himalaya, supported British troops against an Ottoman attack near El Kubri, a genuinely important defensive action protecting one of the empire's most strategically vital waterways.
The Dardanelles
HMS Ocean transferred to the Dardanelles Campaign in late February 1915, taking part in bombardments on 28 February, 4 March, and again on 6 and 7 March, ahead of the major Anglo-French naval assault planned for later that month.
Lost Trying to Save Another Ship's Crew
HMS Ocean met her end on 18 March 1915, during the major Allied assault on the Dardanelles forts, when she moved to assist the disabled British battleship HMS Irresistible, which had already struck a mine and lay helpless under fire. While retrieving Irresistible's surviving crew, HMS Ocean herself was struck by an artillery shell, and at around 19:00 struck a drifting mine of her own. Her starboard coal bunkers and passageways flooded, her steering jammed hard to port, and she developed a dangerous 15-degree list to starboard. The destroyers Jed, Colne and Chelmer moved in around 19:30 to evacuate her crew along with the survivors already rescued from HMS Irresistible, and HMS Ocean, still under fire, drifted into Morto Bay and sank there unobserved by Allied forces at around 22:30 that night, a genuinely striking end for a ship lost not in the act of attacking the enemy, but in the act of trying to save another crew's lives.
