'''HMS ''Monarch''''' was the second of four {{sclass|Orion|battleship|0}} [[dreadnought battleship]]s built for the [[Royal Navy]] in the early 1910s. She spent the bulk of her career assigned to the [[Home Fleet|Home]] and [[Grand Fleet]]s. Aside from participating in the failed attempt to intercept the German ships that had [[Raid on Scarborough, Hartlepool and Whitby|bombarded Scarborough, Hartlepool and Whitby]] in late 1914, the [[Battle of Jutland]] in May 1916 and the inconclusive [[Action of 19 August 1916|action of 19 August]], her service during [[World War I]] generally consisted of routine patrols and training in the [[North Sea]].

After the Grand Fleet was dissolved in early 1919, ''Monarch'' was transferred back to the Home Fleet for a few months before she was assigned to the [[Reserve Fleet (United Kingdom)|Reserve Fleet]]. The ship was listed for disposal in mid-1922, but was [[hulk (ship type)|hulked]] for use as a stationary [[training ship]]. In late 1923 ''Monarch'' was converted into a [[target ship]] and sunk in early 1925.

==Design and description==
The ''Orion''-class ships were designed in response to the beginning of the [[Anglo-German naval arms race]] and were much larger than their predecessors of the {{sclass|Colossus|battleship|||1910}} to accommodate larger, more powerful guns and heavier armour. In recognition of these improvements, the class was sometimes called [[Dreadnought#Super-dreadnoughts|"super-dreadnoughts"]]. The ships had an [[length overall|overall length]] of {{convert|581|ft|m|1}}, a [[Beam (nautical)|beam]] of {{convert|88|ft|6|in|m|1}} and a deep [[Draft (hull)|draught]] of {{convert|31|ft|3|in|m|1}}. They [[Displacement (ship)|displaced]] {{convert|21922|LT|t|lk=in}} at normal load and {{convert|25596|LT|t}} at [[deep load]] as built; by 1918 ''Monarch''{{'}}s deep displacement had increased to {{convert|28556|LT|t}}. Her crew numbered 738 officers and [[naval rating|ratings]] upon completion and 750 as of 1914.<ref name=b1>Burt, p. 136</ref>

The ''Orion'' class was powered by two sets of [[Parsons Marine Steam Turbine Company|Parsons]] [[direct-drive]] [[steam turbine]]s, each driving two shafts, using steam provided by 18 [[Yarrow boiler]]s. The turbines were rated at {{convert|27000|shp|lk=in}} and were intended to give the battleships a speed of {{convert|21|kn|lk=on}}.<ref name=p5>Parkes, p. 525</ref> During her [[sea trial]]s on 9 December 1911, ''Monarch'' reached a maximum speed of {{convert|21.9|kn}} from {{convert|32277|shp|abbr=on}}. The ships carried enough coal and [[fuel oil]] to give them a range of {{convert|6730|nmi|lk=in}} at a cruising speed of {{convert|10|kn}}.<ref>Burt, pp. 136, 139–40</ref>

===Armament and armour===
[[File:Gws monarch 01.jpg|thumb|''Monarch'' firing her [[main battery]], before 1915]]
The ''Orion'' class was equipped with 10 [[List of British ordnance terms#BL|breech-loading (BL)]] [[BL 13.5 inch Mk V naval gun|{{convert|13.5|in|mm|adj=on|sigfig=3}} Mark V guns]] in five hydraulically powered twin-[[gun turret]]s, all on the centreline. The turrets were designated 'A', 'B', 'Q', 'X' and 'Y', from front to rear. Their [[secondary armament]] consisted of 16 [[BL 4 inch naval gun Mk VII|BL {{convert|4|in|mm|adj=on|0}} Mark VII]] guns.  These guns were split evenly between the forward and aft [[superstructure]], all in single mounts. Four [[QF 3-pounder Hotchkiss|3-pounder]] ({{convert|47|mm|in|abbr=on|1|order=flip}}) [[saluting gun]]s were also carried. The ships were equipped with three [[British 21 inch torpedo|21-inch (533&nbsp;mm)]] submerged [[torpedo tube]]s, one on each [[Broadside (naval)|broadside]] and another in the [[stern]], for which 20 torpedoes were provided.<ref name=b1/>

The ''Orion''s were protected by a [[waterline]] {{convert|12|in|adj=on|0}} [[armoured belt]] that extended between the end [[barbette]]s. Their [[deck (ship)|deck]]s ranged in thickness between {{convert|1|in|0}} and 4 inches with the thickest portions protecting the steering gear in the stern. The [[main battery]] turret faces were {{convert|11|in|0}} thick, and the turrets were supported by {{convert|10|in|0|adj=mid|-thick}} barbettes.<ref>Burt, pp. 134, 136, 139</ref>

===Modifications===
In 1914 the shelter-deck guns were enclosed in [[casemate#Single casemates (1889 onwards)|casemates]]<ref name=b40>Friedman, p. 123</ref> and a [[fire-control director]] was installed sometime in 1914, before August, on a platform below the [[Top (sailing ship)|spotting top]].<ref name="dread">{{cite web|title=H.M.S. Monarch (1910)|url=http://www.dreadnoughtproject.org/tfs/index.php/H.M.S._Monarch_(1911)|publisher=The Dreadnought Project|access-date=9 March 2017}}</ref> By October 1914, a pair of {{convert|3|in|0|adj=on}} [[anti-aircraft gun|anti-aircraft (AA) guns]] had been installed. Additional deck armour was added after the Battle of Jutland in May 1916. Around the same time, three 4-inch guns were removed from the aft superstructure and the ship was modified to operate [[kite balloon]]s. A [[Flight deck#Early|flying-off platform]] was mounted on 'B' turret's roof and extended onto the gun barrels during 1917–1918. A high-angle rangefinder was fitted in the forward superstructure by 1921.<ref>Burt, pp. 140, 142; Friedman, pp. 123, 198–200, 205</ref>

==Construction and career==

''Monarch'', named after a [[third-rate]] [[ship of the line]], [[HMS Monarch (1747)|''Monarque'']], that had been captured from the French in 1747,<ref name=s2>Silverstone, p. 252</ref> was the third ship of her name to serve in the Royal Navy.<ref>Colledge, p. 231</ref> The ship was [[laid down]] by [[Armstrong Whitworth]] at their shipyard in [[Elswick, Tyne and Wear|Elswick]] on 1 April 1910 and [[Ceremonial ship launching|launched]] on 30 March 1911.<ref name=g8>Preston, p. 28</ref> She was completed on 31 March 1912, [[Ship commissioning|commissioned]] with a partial crew on 16 April and fully commissioned on 27 April.<ref name=b6/> Including her armament, her cost is variously quoted at [[pound sterling|£]]1,888,736<ref name=b1/> or £1,886,912.<ref name=p5/> ''Monarch'' was assigned to the 2nd [[Division (naval)|division]] of the Home Fleet which was redesignated as the [[2nd Battle Squadron (United Kingdom)|2nd Battle Squadron]] (BS) on 1 May.<ref name=b6>Burt, p. 146</ref> The ship, together with her [[sister ship]]s {{HMS|Thunderer|1911|2}} and {{HMS|Orion|1910|2}}, participated in the [[Fleet Review, Royal Navy|Parliamentary Naval Review]] on 9 July at [[Spithead]]. They then participated in training manoeuvres. The three sisters were present with the 2nd BS to receive the [[President of France]], [[Raymond Poincaré]], at Spithead on 24 June 1913 and then participated in the annual fleet manoeuvres in August.<ref name=b60>Burt, pp. 146, 148, 150</ref>
[[File:British Battleships of the First World War Q39652.jpg|thumb|''Monarch'' entering [[Portsmouth]] harbour, 1913]]

===World War I===
Between 17 and 20 July 1914, ''Monarch'' took part in a test [[mobilisation]] and fleet review as part of the British response to the [[July Crisis]]. Arriving in [[Isle of Portland|Portland]] on 25 July, she was ordered to proceed with the rest of the Home Fleet to [[Scapa Flow]] four days later<ref name=b60/> to safeguard the fleet from a possible surprise attack by the [[Imperial German Navy]].<ref>Massie, p. 19</ref> Following the outbreak of World War I in August, the Home Fleet was reorganised as the [[Grand Fleet]], and placed under the command of [[Admiral (Royal Navy)|Admiral]] Sir [[John Jellicoe, 1st Earl Jellicoe|John Jellicoe]].<ref>Preston, p. 32</ref> On 8 August, ''Monarch'' was conducting gunnery practice south-east of [[Fair Isle]] when she was unsuccessfully attacked by a [[submarine]]-fired torpedo. This was probably a false alarm as the area was too far to the west of the German [[U-boat]]s' patrol zones to be likely.<ref>Goldrick, p. 89</ref> {{SMU|U-15|Germany|6}}, however, has been suggested as a candidate for the attack, although the boat was sunk the following day with the loss of all hands and the truth will never be known.<ref>Showell, p. 41</ref>
[[File:2nd Battle Squadron.jpg|thumb|left|The 2nd BS sailing through the [[Solent]], about 1914. From left to right, {{HMS|King George V|1911|2}}, ''Thunderer'', ''Monarch'', and {{HMS|Conqueror|1911|2}}]]
Repeated reports of submarines in Scapa Flow led Jellicoe to conclude that the defences there were inadequate and he ordered that the Grand Fleet be dispersed to other bases until the defences be reinforced. On 16 {{nat|October the 2nd}} BS was sent to [[Loch na Keal]] on the western coast of Scotland. The [[squadron (naval)|squadron]] departed for gunnery practice off the northern coast of Ireland on the morning of 27 October and the dreadnought {{HMS|Audacious|1912|2}} struck a [[naval mine|mine]], laid a few days earlier by the German [[armed merchant cruiser]] {{SS|Berlin|1908|6}}. Thinking that the ship had been torpedoed by a submarine, the other dreadnoughts were ordered away from the area, while smaller ships rendered assistance. On the evening of 22 November 1914, the Grand Fleet conducted a fruitless sweep in the southern half of the [[North Sea]]; ''Monarch'' stood with the main body in support of [[Vice-Admiral (Royal Navy)|Vice-Admiral]] [[David Beatty, 1st Earl Beatty|David Beatty]]'s [[1st Battlecruiser Squadron]]. The fleet was back in port in Scapa Flow by 27 November.<ref>Goldrick, p. 156; Jellicoe, pp. 143–44, 148, 163–65</ref>

==== Bombardment of Scarborough, Hartlepool, and Whitby ====
{{main|Raid on Scarborough, Hartlepool and Whitby}}
The Royal Navy's [[Room 40]] had [[Signals intelligence|intercepted and decrypted German radio traffic]] containing plans for a German attack on [[Scarborough, North Yorkshire|Scarborough]], [[Hartlepool]] and [[Whitby]] in mid-December using the four [[battlecruiser]]s of ''[[Konteradmiral]]'' (Rear-Admiral) [[Franz von Hipper]]'s [[I Scouting Group]]. The radio messages did not mention that the [[High Seas Fleet]] with fourteen dreadnoughts and eight [[pre-dreadnought]]s would reinforce Hipper. The ships of both sides departed their bases on 15 December, with the British intending to ambush the German ships on their return voyage. They mustered the six dreadnoughts of Vice-Admiral [[Sir George Warrender, 7th Baronet|Sir George Warrender]]'s 2nd BS, including ''Monarch'' and her [[sister ship]]s, ''Orion'' and ''Conqueror'', and Beatty's four battlecruisers.<ref>Tarrant, pp. 28–30</ref>

The screening forces of each side blundered into each other during the early morning darkness and heavy weather of 16 December. The Germans got the better of the initial exchange of fire, severely damaging several British [[destroyer]]s, but Admiral [[Friedrich von Ingenohl]], commander of the High Seas Fleet, ordered his ships to turn away, concerned about the possibility of a massed attack by British destroyers in the dawn's light. A series of miscommunications and mistakes by the British allowed Hipper's ships to avoid an engagement with Beatty's forces.<ref>Goldrick, pp. 200–14</ref>

====1915–1916====
[[File:Battleship HMS Monarch - IWM Q 75217.jpg|thumb|''Monarch'' in the Portsmouth area, a [[Short Type 184]] overhead]]
The Grand Fleet conducted another fruitless sweep of the North Sea in late December and, while trying to enter Scapa Flow in a [[Beaufort scale|Force 8]] [[gale]] and minimal visibility, ''Monarch'' was accidentally [[naval ram|rammed]] by ''Conqueror'' on 27 December. The former had to unexpectedly manoeuvre to avoid a [[guardship]] at the entrance and ''Conqueror'' could not avoid her. ''Monarch'' suffered moderate damage to her [[stern]] and received temporary repairs at Scapa before proceeding to [[HMNB Devonport|Devonport]] for full repairs on 4 January 1915, rejoining the Grand Fleet on 20 January.<ref>Burt, pp. 146, 148; Goldrick, p. 242</ref>

On the evening of 23 January, the bulk of the Grand Fleet sailed in support of Beatty's battlecruisers, but ''Monarch'' and the rest of the fleet did not participate in the ensuing [[Battle of Dogger Bank (1915)|Battle of Dogger Bank]] the following day. On 7–10 March, the Grand Fleet conducted a sweep in the northern North Sea, during which it conducted training manoeuvres. Another such cruise took place on 16–19 March. On 11 April, the Grand Fleet conducted a patrol in the central North Sea and returned to port on 14 April; another patrol in the area took place on 17–19 April, followed by gunnery drills off [[Shetland]] on 20–21 April.<ref>Jellicoe, pp. 194–196, 206, 211–212</ref>

The Grand Fleet conducted sweeps into the central North Sea on 17–19 May and 29–31 May without encountering any German vessels. During 11–14 June, the fleet conducted gunnery practice and battle exercises west of Shetland<ref>Jellicoe, pp. 217–219, 221–222</ref> and more training off Shetland beginning on 11 July. The 2nd BS conducted gunnery practice in the [[Moray Firth]] on 2 August and then returned to Scapa Flow. On 2–5 September, the fleet went on another cruise in the northern end of the North Sea and conducted gunnery drills. Throughout the rest of the month, the Grand Fleet conducted numerous training exercises. The ship, together with the majority of the Grand Fleet, conducted another sweep into the North Sea from 13 to 15 October. Almost three weeks later, ''Monarch'' participated in another fleet training operation west of [[Orkney]] during 2–5 November and repeated the exercise at the beginning of December.<ref>Jellicoe, pp. 228, 234–235, 243, 246, 250, 253, 257–258</ref>

[[File:Orion-class BBs SP 1703.jpeg|thumb|The four ''Orion''-class battleships in [[line ahead]] formation, after 1915]]
The Grand Fleet sortied in response to an attack by German ships on British light forces near Dogger Bank on 10 February 1916, but it was recalled two days later when it became clear that no German ships larger than a destroyer were involved. The fleet departed for a cruise in the North Sea on 26 February; Jellicoe had intended to use the [[Harwich Force]] to sweep the [[Heligoland Bight]], but bad weather prevented operations in the southern North Sea. As a result, the operation was confined to the northern end of the sea. Another sweep began on 6 March, but had to be abandoned the following day as the weather grew too severe for the escorting destroyers. On the night of 25 March, ''Monarch'' and the rest of the fleet sailed from Scapa Flow to support Beatty's battlecruisers and other light forces raiding the German [[Zeppelin]] base at [[Tondern]]. By the time the Grand Fleet approached the area on 26 March, the British and German forces had already disengaged and a strong [[gale]] threatened the light craft, so the fleet was ordered to return to base. On 21 April, the Grand Fleet conducted a demonstration off [[Horns Reef]] to distract the Germans while the [[Imperial Russian Navy]] relaid its defensive [[minefields]] in the [[Baltic Sea]].<ref>Jellicoe, pp. 270–271, 275, 279–280, 284, 286</ref> The fleet returned to Scapa Flow on 24 April and refuelled before proceeding south in response to intelligence reports that the Germans were about to launch a [[Bombardment of Yarmouth and Lowestoft|raid on Lowestoft]], but only arrived in the area after the Germans had withdrawn. On 2–4 May, the fleet conducted another demonstration off Horns Reef to keep German attention focused on the North Sea.<ref>Jellicoe, pp. 286–290</ref>

====Battle of Jutland====
[[File:Map of the Battle of Jutland, 1916.svg|thumb|upright=1.7|Maps showing the manoeuvres of the British (blue) and German (red) fleets on 31 May&nbsp;– 1 June 1916|alt=The British fleet sailed from northern Britain to the east while the Germans sailed from Germany in the south; the opposing fleets met off the Danish coast]]
{{Main|Battle of Jutland}}
In an attempt to lure out and destroy a portion of the Grand Fleet, the High Seas Fleet, composed of sixteen dreadnoughts, six pre-dreadnoughts and supporting ships, departed the [[Jade Bight]] early on the morning of 31 May. The fleet sailed in concert with Hipper's five battlecruisers. Room 40 had intercepted and decrypted German radio traffic containing plans of the operation. In response the Admiralty ordered the Grand Fleet, totalling some 28 dreadnoughts and 9 battlecruisers, to sortie the night before to cut off and destroy the High Seas Fleet.<ref>Tarrant, pp. 54–55, 57–58</ref>

On 31 May, ''Monarch'', under the command of [[Captain (Royal Navy)|Captain]] [[George Borrett]], was the sixth ship from the head of the [[battle line]] after deployment.<ref>Corbett, frontispiece map and p. 428</ref> During the first stage of the general engagement, the ship fired three [[salvo]]s of [[Armor-piercing shot and shell|armour-piercing, capped (APC)]] shells from her main guns at a group of five battleships at 18:32, scoring one hit on the dreadnought {{SMS|König}} that knocked out a {{convert|15|cm|1|adj=on}} gun, temporarily disabled three boilers and started several small fires.<ref group=Note>The times used in this section are in [[Universal Time|UT]], which is one hour behind [[Central European Time|CET]], which is often used in German works.</ref> At 19:14, she engaged the battlecruiser {{SMS|Lützow}} at a range of {{convert|17300|-|18450|yd|m}} with five salvos of APC shells and claimed to [[wikt:straddle|straddle]] her with the last two salvos. ''Lützow'' was also fired at by ''Orion'' during this time and was hit five times between the sisters. They knocked out two of her main guns, temporarily knocked out the power to the sternmost turret and caused a fair amount of flooding. This was the last time that ''Monarch'' fired her guns during the battle, having expended a total of fifty-three 13.5-inch APC shells.<ref>Campbell, pp. 156, 188, 193, 209, 218–20, 346–47</ref>

====Subsequent activity====
[[File:HMS Monarch Q 74177.jpg|thumb|''Monarch'' at anchor in Scapa Flow, June 1917]]
The Grand Fleet sortied on 18 August to ambush the High Seas Fleet while it advanced into the southern North Sea, but a series of miscommunications and mistakes prevented Jellicoe from intercepting the German fleet before it returned to port. Two light cruisers were sunk by German [[U-boat]]s during the operation, prompting Jellicoe to decide to not risk the major units of the fleet south of 55° 30' North due to the prevalence of German submarines and mines. The [[British Admiralty|Admiralty]] concurred and stipulated that the Grand Fleet would not sortie unless the German fleet was attempting an invasion of Britain or there was a strong possibility it could be forced into an engagement under suitable conditions.<ref>Halpern, pp. 330–32</ref>

In April 1918, the High Seas Fleet again sortied, to attack British convoys to Norway. They enforced strict wireless silence during the operation, which prevented Room 40 cryptanalysts from warning the new commander of the Grand Fleet, Admiral Beatty. The British only learned of the operation after an accident aboard the battlecruiser {{SMS|Moltke}} forced her to break radio silence to inform the German commander of her condition. Beatty then ordered the Grand Fleet to sea to intercept the Germans, but he was not able to reach the High Seas Fleet before it turned back for Germany.<ref>Halpern, pp. 418–20</ref> The ship was present at [[Rosyth]], Scotland, when the High Seas Fleet surrendered there on 21 November<ref>{{cite web|title=Operation ZZ|url=http://www.dreadnoughtproject.org/tfs/index.php/Operation_ZZ|publisher=The Dreadnought Project|access-date=10 March 2017}}</ref> and she remained part of the 2nd BS through 1 March 1919.<ref>{{cite web|title=Supplement to the Monthly Navy List Showing the Organisation of the Fleet, Flag Officer's Commands, &c.|url=http://digital.nls.uk/british-military-lists/pageturner.cfm?id=92419634&mode=fullsize|website=National Library of Scotland|publisher=Admiralty|date=1 March 1919|access-date=17 March 2017|page=10}}{{Dead link|date=December 2025 |bot=InternetArchiveBot }}</ref>

On 5 May 1922, ''Monarch'' was [[paid off]] and placed on the disposal list in accordance with the terms of the [[Washington Naval Treaty]]. Put up for sale in August, the ship was later withdrawn and attached to the gunnery school at {{HMS|Vernon|shore establishment|2}} as a [[hulk (ship type)|hulk]].<ref>Burt, p. 148</ref>

She was attacked by a wave of [[Royal Air Force]] bombers, which scored several hits; this was followed by four {{sclass2|C|cruiser|0}} [[light cruiser]]s firing six-inch (152-mm) shells, and the destroyer {{HMS|Vectis|D51|2}}, using her 4-inch guns. For the finale, the fast battleships {{HMS|Hood|51|2}} and {{HMS|Repulse|1916|2}} and the five {{sclass|Revenge|battleship|2}}s opened fire with their 15-inch (381-mm) guns.
