Design and description
The Sentinel-class ships were one of four classes of scout cruisers ordered by the Admiralty in 1902–1903 and 1903–1904 Naval Programmes. These ships were intended to work with destroyer flotillas, leading their torpedo attacks and backing them up when attacked by other destroyers, although they quickly became less useful as destroyer speeds increased before the First World War. They had a length between perpendiculars of 360 feet (109.7 m), a beam of 40 feet (12.2 m) and a draught of 14 feet 39 inches (5.3 m) at deep load. The ships displaced 2,895 long tons (2,941 t) at normal load and 3,100 long tons (3,150 t) at deep load. Their crew consisted of 289 officers and ratings. [1]
The ships were powered by a pair of three-cylinder triple-expansion steam engines, each driving one shaft, using steam provided by a dozen Vickers Express water-tube boilers. The engines were designed to produce a total of 16,500 indicated horsepower (12,300 kW) which was intended to give a maximum speed of 25 knots (46 km/h; 29 mph). [2] When Sentinel ran her sea trials, she reached a speed of 25.1 knots (46.5 km/h; 28.9 mph) from 16,433 ihp (12,254 kW) for eight hours. [3] The Sentinel-class cruisers carried enough coal to give them a range of 2,460 nautical miles (4,560 km; 2,830 mi) at 10 knots (19 km/h; 12 mph). [4]
The main armament of the Sentinel class consisted of ten quick-firing (QF) 12-pounder 3 in (76 mm) 18-cwt guns. [Note 1] [5] Three guns were mounted abreast on the forecastle and the quarterdeck, with the remaining four guns positioned port and starboard amidships. They also carried eight 3-pounder Hotchkiss guns and two above-water 18-inch (450 mm) torpedo tubes, one on each broadside. The ships' protective deck armour ranged in thickness from 0.625 to 1.5 inches (16 to 38 mm) and the conning tower had armour 3 inches (76 mm) inches thick. [2]
Career
Sentinel was laid down by Vickers Limited at their shipyard in Barrow-in-Furness on 8 June 1903, launched on 19 April 1904 and completed in April 1905. [6] She was originally to be named HMS Inchkeith, but was renamed in 1903, prior to launching. [7] Not long after completion, two additional 12-pounder guns were added and the 3-pounder guns were replaced with six QF 6-pounder Hotchkiss guns. [2] The ship began her career with the 3rd Cruiser Squadron in the Mediterranean in 1906, before being recalled to join the Channel Fleet, and then reduced to reserve in the Home Fleet from 1907. In February 1910 she was recommissioned as the leader of the 5th Destroyer Flotilla at Chatham and refitted there in June. [8] About 1911–1912, her main guns were replaced by nine 4-inch (102 mm) guns, arranged four on each broadside and the remaining gun on the quarterdeck. [9] After another refit in 1912 at HM Dockyard, Devonport, Sentinel was assigned to the 3rd Light Cruiser Squadron in 1913 for the annual manoeuvres and was then transferred to lead the 9th Destroyer Flotilla at Portsmouth. The ship joined the 6th Destroyer Flotilla at Dover later that year. [8]
After the start of the First World War in August 1914, Sentinel was serving with the 8th Destroyer Flotilla in the Firth of Forth. In 1915 she was temporarily assigned with 6th Light Cruiser Squadron in the Humber to defend against Zeppelin raids, before she was transferred to the Mediterranean and then to the Aegean in 1918. Later that year, Sentinel was part of the squadron sent through the Dardanelles to undertake duties in the Black Sea, where Britain was becoming involved in the Russian Civil War. The ship paid off in April 1919 at Sheerness and served as a mechanic’s training ship at Chatham from July 1920 until the end of 1922 before being sold for scrap in January 1923. [8]
HMS Carnarvon was one of six Devonshire-class armoured cruisers built for the Royal Navy in the first decade of the 20th century. She was assigned to the 3rd Cruiser Squadron of the Mediterranean Fleet upon completion in 1905 and was transferred to the 2nd Cruiser Squadron of the Atlantic Fleet in 1907. She was assigned to the reserve Third Fleet in 1909 and became flagship of the 5th Cruiser Squadron of the reserve Second Fleet in 1912.
The Boadicea-class cruiser was a pair of scout cruisers built for the Royal Navy in the first decade of the 20th century. They were the first class of this type to be fitted with steam turbine machinery. Upon completion in 1909–10, the sister ships served as flotilla leaders for destroyer flotillas of the First Fleet until 1913 when they were assigned to battleship squadrons. When the First World War began in August 1914, they remained with their squadrons as the First Fleet was incorporated into the Grand Fleet, although they changed squadrons over the course of the war. Both ships were present during the Battle of Jutland in mid-1916, but neither fired a shot. They were converted into minelayers the following year and both ships laid minefields in early 1918 in addition to other missions. The sisters were reduced to reserve in 1919 and sold for scrap in 1921 and 1926.
HMS Suffolk was one of 10 Monmouth-class armoured cruisers built for the Royal Navy in the first decade of the 20th century. Upon completion she was assigned to the 3rd Cruiser Squadron of the Mediterranean Fleet and was then assigned to the 5th Cruiser Squadron in the Mediterranean in 1909 after a lengthy refit. She returned home for another refit in 1912 and became the flagship of the 4th Cruiser Squadron on the North America and West Indies Station in 1913.
HMS Orwell was a B-class torpedo boat destroyer of the British Royal Navy. She was built by Laird, Son & Company, and served from 1900 until 1920.
HMS Berwick was one of 10 Monmouth-class armoured cruisers built for the Royal Navy in the first decade of the 20th century. She was assigned to the 2nd Cruiser Squadron of the Channel Fleet upon completion in 1903 and was transferred to the Home Fleet in 1906. She accidentally rammed and sank a British destroyer in 1908. Berwick was refitted in 1908–09 before she was transferred to the 4th Cruiser Squadron on the North America and West Indies Station later that year.
HMS Lancaster was one of 10 Monmouth-class armoured cruisers built for the Royal Navy in the first decade of the 20th century. Upon completion she was assigned to the 3rd Cruiser Squadron of the Mediterranean Fleet. She remained there until 1912 when she returned home to be placed in reserve. The ship was recommissioned in 1913 for service with the 4th Cruiser Squadron on the North America and West Indies Station. She remained there until she was assigned to the Grand Fleet in 1915. She was transferred to the Pacific in 1916 and she became flagship of the Eastern Squadron in 1918. The ship was sold for scrap in 1920.
The Active-class cruisers were a trio of scout cruisers built for the Royal Navy shortly before the First World War. They were initially assigned to the First Fleet and became destroyer flotilla leaders in 1914. Amphion and Fearless and their flotillas were assigned to the Harwich Force when the war began in August 1914. They went out on a patrol on the first day of the war and Amphion and her destroyers encountered and sank a German minelayer. On the voyage home, the cruiser struck a mine laid by the German ship and sank. She was the first ship of the Royal Navy to be sunk in the war.
HMS Blonde was the lead ship of her class of scout cruisers built for the Royal Navy in the first decade of the 20th century. She led the Seventh Destroyer Flotilla in the Mediterranean Fleet from completion until 1912. The ship was temporarily assigned to the First Destroyer Flotilla before she joined the Fourth Battle Squadron in 1913. During the First World War, Blonde was assigned to various battleship squadrons of the Grand Fleet. The ship was converted into a minelayer in 1917, but never actually laid any mines. She was reduced to reserve in 1919 and sold for scrap in 1920.
HMS Skirmisher was one of two Sentinel-class scout cruisers built for the Royal Navy during the first decade of the 20th century. Completed in 1905 the ship was placed in reserve until she was commissioned in 1907 as part of the Home Fleet. She then spent the next seven years moving on and off of active service in British waters. Skirmisher was assigned to coastal defence duties when the First World War began in 1914, although she was transferred to the Mediterranean in 1915 and then to the Aegean two years later. The ship returned home in mid-1919 and was sold for scrap in 1920.
The Sentinel-class cruisers were a pair of scout cruisers built for the Royal Navy in the first decade of the 20th century. The sister ships spent about half of the first decade of their careers in reserve and were based in home waters when on active duty. When the First World War began in August 1914 they were given coastal defence missions on the north eastern coast of Britain. The ships were transferred to the Mediterranean in 1915 and then to the Aegean in mid-1916 where they remained until the end of the war in late 1918. Skirmisher was paid off in 1919 and was scrapped the following year, but Sentinel supported the British attempt to intervene in the Russian Civil War for a few months after the end of the war. She also returned home in 1919, but served as a training ship for a few years before she was broken up in 1923.
HMS Patrol was one of two Pathfinder-class scout cruisers which served built for the Royal Navy in the first decade of the 20th century. The ship was in reserve for most of the first decade of her existence. After the beginning of the First World War in August 1914, she was assigned to coastal defence duties on the East Coast of England. Patrol was badly damaged during the German bombardment of Hartlepool in mid-December 1914 when she attempted to exit the harbour during the bombardment. After repairs were completed she remained on coast defence duties until she was transferred to the Irish Sea in 1918. The ship was paid off in 1919 and sold for scrap in 1920.
The Pathfinder-class cruisers were a pair of scout cruisers built for the Royal Navy in the first decade of the 20th century. The sister ships spent much of the first decade of their careers in reserve. When the First World War began in August 1914 they were given coastal defence missions, Pathfinder on the coast of Scotland and Patrol on the coast of Yorkshire. The latter ship was badly damaged when the Germans bombarded Hartlepool in December. She spent the rest of the war in British waters. The ship was paid off in 1919 and sold for scrap the following year. Pathfinder was sunk by a German submarine shortly after the war began, the first sinking of a British warship during the war by a German submarine.
The Forward-class cruisers were a pair of scout cruisers built for the Royal Navy in the first decade of the 20th century. The sister ships spent much of the first decade of their careers in reserve. When the First World War began in August 1914 they were given coastal defence missions, Foresight in the English Channel and Forward on the coast of Yorkshire. The latter ship was in Hartlepool when the German bombarded it in December, but never fired a shot. The ships were transferred to the Mediterranean in 1915 and then to the Aegean in mid-1916 where they remained until 1918. They survived the war, but were scrapped shortly afterwards.
HMS Forward was the name ship of her class of two scout cruisers built for the Royal Navy in the first decade of the 20th century. The ship was in reserve for most of the first decade of her existence. After the beginning of the First World War in August 1914, she was assigned to coastal defence duties on the East Coast of England. Forward was present when the Germans bombarded Hartlepool in mid-December 1914, but played no significant role in the battle. The ship was sent to the Mediterranean in mid-1915 and was then assigned to the Aegean Sea a year later, together with her sister ship, Foresight, and remained there until the end of the war. After returning home in 1919, she was sold for scrap in 1921.
HMS Foresight was one of two Forward-class scout cruisers built for the Royal Navy during the first decade of the 20th century. The ship was in reserve for most of the first decade of her existence. After the beginning of the First World War in August 1914, she was initially assigned to the Dover Patrol and was then transferred to the 8th Destroyer Flotilla. Foresight was sent to the Mediterranean in mid-1915 and was then assigned to the Aegean Sea a year later, together with her sister ship, Forward, and remained there until the end of the war. After returning home in 1919, she was sold for scrap in 1920.
The Adventure-class cruisers were a pair of scout cruisers built for the Royal Navy in the first decade of the 20th century. The sister ships spent about half of the first decade of their careers in reserve and were based in home waters when on active duty. During this time Attentive was involved in two collisions. When the First World War began in August 1914 the ships were given coastal defence missions on the English Channel. Attentive was transferred to Ireland in mid-1915, but Adventure remained with the Dover Patrol for another three years. They were assigned convoy escort duties in the Atlantic Ocean in 1918 before being separated when Attentive was transferred to the Mediterranean and Adventure was tasked to support the British intervention in North Russia. The sisters returned home a few months after the end of the war in November 1918 and were sold for scrap in 1920.
HMS Adventure was the name ship of her class of two scout cruisers built for the Royal Navy during the first decade of the 20th century. For two years after being completed in 1905, the ship was in reserve. She was commissioned in mid-1907 as a flotilla leader in the Home Fleet. When the First World War began in August 1914, she was assigned to patrol the English Channel. In mid-1915 Adventure was transferred to Irish waters to serve as the flagship there. In early 1918, the ship escorted convoys to Gibraltar before being transferred to the Mediterranean at the end of the war. She returned home in mid-1919 and was paid off. Adventure was sold for scrap in early 1920.
HMS Attentive was one of two Adventure-class scout cruisers built for the Royal Navy during the first decade of the 20th century. Completed in 1905 the ship was placed in reserve until she was commissioned in 1907 as part of the Home Fleet. She then spent the next seven years moving on and off of active service in British waters. The ship sank one destroyer and damaged two others in collisions. Attentive was assigned to coastal defence duties when the First World War began in 1914, and spent most of the war assigned to the Dover Patrol. She played a minor role in the Zeebrugge Raid in early 1918 and was then assigned to escort convoys to Gibraltar. The ship was sent to the White Sea later in the year to support the unsuccessful North Russia intervention in the Russian Civil War. Attentive paid off at the end of 1918 and was sold for scrap in 1920.
HMS Welland was a Yarrow-built River-class destroyer ordered by the Royal Navy under the 1902 – 1903 Naval Estimates. Named after the River Welland that drains into the Wash on the English east coast, she was the first ship to carry this name in the Royal Navy.
HMS Gala was a Yarrow type River-class destroyer ordered by the Royal Navy under the 1903 – 1904 Naval Estimates. Named after the Gala Waters in the Scottish Borders area south of Edinburgh, she was the first Royal Navy ship to carry this name. She was launched on 7 January 1905 and was accidentally sunk in a collision with the cruiser Attentive on 28 April 1908.
