Question: Which naval battle was the HMS Royal Oak fighting in off the North Sea coast of Denmark?

<P0-S0> The Battle of Jutland (German: "Skagerrakschlacht" , the Battle of Skagerrak) was a naval battle fought by the British Royal Navy's Grand Fleet under Admiral Sir John Jellicoe, against the Imperial German Navy's High Seas Fleet under Vice-Admiral Reinhard Scheer during the First World War. <P0-S1>  It was the largest naval battle and the only full-scale clash of battleships in that war. <P0-S2>  Jutland was the third fleet action between steel battleships, following the smaller but more decisive battles of the Yellow Sea (1904) and Tsushima (1905) during the Russo-Japanese War. <P0-S3>  Jutland was the last major battle in world history fought primarily by battleships. <P0-S4>  The battle unfolded in extensive maneuvering and three main engagements (the battlecruiser action, the fleet action and the night action), from 31 May to 1 June 1916, off the North Sea coast of Denmark's Jutland Peninsula. <SEP> <P1-S0> HMS "Queen Mary" was the last battlecruiser built by the Royal Navy before World War I. <P1-S1>  The sole member of her class, "Queen Mary" shared many features with the "Lion"-class battlecruiser s, including her eight 13.5 in guns. <P1-S2>  She was completed in 1913 and participated in the Battle of Heligoland Bight as part of the Grand Fleet in 1914. <P1-S3>  Like most of the modern British battlecruisers, she never left the North Sea during the war. <P1-S4>  As part of the 1st Battlecruiser Squadron, she attempted to intercept a German force that bombarded the North Sea coast of England in December 1914, but was unsuccessful. <P1-S5>  She was refitting in early 1915 and missed the Battle of Dogger Bank in January, but participated in the largest fleet action of the war, the Battle of Jutland in mid-1916. <P1-S6>  She was hit twice by the German battlecruiser "Derfflinger" during the early part of the battle and her magazines exploded shortly afterwards, sinking the ship. <SEP> <P2-S0>  Launched in 1914 and completed in 1916, "Royal Oak" first saw combat at the Battle of Jutland as part of the Grand Fleet. <P2-S1>  In peacetime, she served in the Atlantic, Home and Mediterranean fleets, more than once coming under accidental attack. <P2-S2>  The ship drew worldwide attention in 1928 when her senior officers were controversially court-martialled. <P2-S3>  Attempts to modernise "Royal Oak" throughout her 25-year career could not fix her fundamental lack of speed and by the start of the Second World War, she was no longer suited to front-line duty. <P2-S4> HMS "Royal Oak" was one of five "Revenge"-class battleship s built for the Royal Navy during the First World War. <SEP> <P3-S0> William Brown (8 May 1764 – 20 September 1814) was an officer of the British Royal Navy who served in increasingly senior positions during a long period from the American Revolutionary War, including the French Revolutionary War, and until the Napoleonic Wars. <P3-S1>  He began his naval career as a servant to Captain Philemon Pownoll in the frigate HMS Apollo and became a midshipman after two years. <P3-S2>  He then served on HMS Resolution with Lord Robert Manners and came home with him in HMS Andromache. <P3-S3>  He spent the next five years ashore in peacetime. <P3-S4>  After a brief time on HMS Bounty he was taken off by the First lord and moved to HMS Ariel before the Bounty sailed. <P3-S5>  He was then moved to HMS Leander, where he was commissioned by Admiral Peyton in 1788. <P3-S6>  He later captained a series of ships serving in the Mediterranean, the North Sea, the Channel Fleet and then the Mediterranean, again with lord St Vincent. <P3-S7>  He captained HMS Ajax in the Blockade of Brest and the Battle of Cape Finisterre and then at Cadiz at Nelson's personal request. <P3-S8>  After Trafalgar he had a series of shore postings as Dockyard Commissioner at Malta and Shearness before being made Commander in Chief of the Channel Islands and then Jamaica where he died.
