HMS Duncan was the lead ship of the six-ship Duncan class of Royal Navy pre-dreadnought battleships. Commissioned in 1903, she served with the Mediterranean Fleet until 1905, at which she was transferred to the Channel Fleet. Damaged in a collision with HMS Albion in late 1905, she was damaged again when she ran aground off Lundy Island. After a further stint with the Mediterranean Fleet, in 1913 she was assigned to the 6th Battle Squadron and based at Portsmouth, where she served as a gunnery training ship.

Duncan was being refitted when World War I broke out. When the refit was completed, she conducted operations as part of the Northern Patrol, and served with her sister ships in the Channel Fleet. She left the squadron in February 1915 for a further refit after which she was assigned to the 9th Cruiser Squadron on the Finisterre-Azores-Madeira Station. In late 1915, she returned once again to the Mediterranean, conducting operations in support of the Italian Navy and then against Greek royalists. From 1917, she spent the remainder of the war in England waters as a reserve ship and was decommissioned in 1919.

Technical description

HMS Duncan was laid down by Thames Ironworks and Shipbuilding Company, Leamouth, on 10 July 1899, and launched on 21 March 1901 by Mrs. Hills, wife of Mr. Arnold Hills, chairman of the company.[5] She left the Victoria Dock for Chatham in May 1902,[6] for armament and trials, and was completed in October 1903.[1]

Duncan and her five sister battleships of the Duncan class were ordered in response to large French and Russian building programmes,[2] including an emphasis on fast battleships in the Russian programme;[7] they were designed as smaller, more lightly armored, and faster versions of the preceding Formidable class.[2] As it turned out, the Russian ships were not as heavily armed as initially feared, and the Duncans proved to be quite superior in their balance of speed, firepower, and protection.[7]

Armour layout was similar to that of London, with reduced thickness in the barbettes and belt.[2]

Duncan and her sisters had machinery capable of 3,000 indicated horsepower (2,200 kW) more than the Formidables and Londons and were the first British battleships with 4-cylinder triple-expansion engines. They also had a modified hull form to improve speed. The ships had a reputation as good steamers, with a designed speed of 19 knots (35 km/h; 22 mph) and an operational speed of 18 knots (33 km/h; 21 mph),[2] good steering at all speeds, and an easy roll. They were the fastest battleships in the Royal Navy when completed, and the fastest pre-dreadnoughts ever built other than the Swiftsure-class Swiftsure and Triumph.[8]

They had the same armament as and a smaller displacement than the Formidables and Londons.[2]

Like all predreadnoughts, Duncan was outclassed by the dreadnought battleships that began to appear in 1906, but she nonetheless continued to perform front-line duties up through the early part of World War I.

Operational history

Pre-World War I

HMS Duncan commissioned at Chatham Dockyard on 8 October 1903 for Mediterranean Fleet service. She transferred to the Channel Fleet in February 1905. On 26 September 1905, she collided with the battleship HMS Albion at Lerwick, suffering hull damage including a hole in her side below the waterline, rudder damage, and the loss of her sternwalk. She suffered another mishap on 23 July 1906, when she grounded off Lundy Island during unsuccessful operations to salvage the battleship HMS Montagu.[9]

Duncan transferred to the Atlantic Fleet in February 1907, and underwent a refit at Gibraltar from November 1907 to February 1908. On 1 December 1908, Duncan transferred to the Mediterranean Fleet to serve as Second Flagship. She underwent a refit at Malta in 1909. Under a fleet reorganisation on 1 May 1912, the Mediterranean Fleet became the 4th Battle Squadron, Home Fleet, and changed its base from Malta to Gibraltar; Duncan thus became a unit of the squadron at Gibraltar.[10]

On 27 May 1913, Duncan recommissioned at Chatham with a nucleus crew and was assigned to the 6th Battle Squadron in the Second Fleet at Portsmouth, where she served as a gunnery training ship in the commissioned reserve. She began a refit at Chatham in May 1914.[10]

World War I

Duncan was still undergoing her refit when World War I began in August 1914.[10] Plans originally called for Duncan and battleships Agamemnon, Albemarle, Cornwallis, Exmouth, Russell, and Vengeance to form the 6th Battle Squadron in wartime and serve in the Channel Fleet, where the squadron was to patrol the English Channel and cover the movement of the British Expeditionary Force to France. However, plans also existed for the 6th Battle Squadron to be assigned to the Grand Fleet, and, when the war began, the Commander-in-Chief, Grand Fleet, Admiral Sir John Jellicoe, requested that Duncan and her four surviving sister ships of the Duncan class (Albemarle, Cornwallis, Exmouth, and Russell) be assigned to the 3rd Battle Squadron in the Grand Fleet for patrol duties to make up for the Grand Fleet's shortage of cruisers. Accordingly, the 6th Battle Squadron was abolished temporarily, and, upon completion of her refit in September 1914, Duncan joined the 3rd Battle Squadron at Scapa Flow, where she joined the Grand Fleet's cruisers on duty in the Northern Patrol.[11]

Duncan and her four Duncan-class sisters, as well as the battleships of the King Edward VII class, temporarily were transferred to the Channel Fleet on 2 November 1914 to reinforce that fleet in the face of Imperial German Navy activity in the Channel Fleet's area. On 13 November 1914, the King Edward VII-class ships returned to the Grand Fleet, but Duncan and her sister ships stayed in the Channel Fleet, where they reconstituted the 6th Battle Squadron on 14 November 1914. This squadron was given a mission of bombarding German submarine bases on the coast of Belgium, and was based at Portland, although it transferred to Dover immediately on 14 November 1914. However, due a lack of antisubmarine defenses at Dover, the squadron returned to Portland on 19 November 1914.[12]

The 6th Battle Squadron returned to Dover in December 1914, then transferred to Sheerness on 30 December 1914 to relieve the 5th Battle Squadron there in guarding against a German invasion of the United Kingdom.[13]

Between January and May 1915, the 6th Battle Squadron was dispersed. Duncan left the squadron in February 1915 to be reduced to reserve for a refit at Chatham that lasted until July 1915. She recommissioned at Chatham on 19 July 1915 and was attached to the 9th Cruiser Squadron on the Finisterre-Azores-Madeira Station.[14]

In August 1915, Duncan transferred to the 2nd Detached Squadron in the Adriatic Sea. The squadron had been organized in May 1915 to reinforce the Italian Navy against the Austro-Hungarian Navy after Italy declared war on Austria-Hungary. Duncan was based at Taranto, Italy, during this service.[10]

In June 1916, Duncan transferred to the 3rd Detached Squadron in the Aegean Sea, based at Salonika. From October to December 1916, she participated in operations against Greek royalists, and landed Royal Marines at Athens on 1 December 1916. She returned to the Adriatic Squadron in January 1917.[10]

Decommissioning and reserve

In February 1917, Duncan returned to the United Kingdom and paid off at Sheerness to provide crews for antisubmarine vessels. She was in reserve at Sheerness until April 1917, when she moved to Chatham for a refit. Upon completion of her refit in January 1918, she remained in reserve at Chatham, serving as an accommodation ship.[10]


Duncan was placed on the disposal list in March 1919, and was sold for scrapping to Stanlee Shipbreaking Company Limited, Dover, on 18 February 1920. She was towed to Dover for scrapping in June 1920.[10]
