1916 naval battle during World War I
The Battle of Jutland () was a naval battle between Britain's Royal Navy Grand Fleet, under Admiral Sir John Jellicoe, and the Imperial German Navy's High Seas Fleet, under Vice-Admiral Reinhard Scheer, during World War I. The battle unfolded in extensive manoeuvring and three main engagements from 31 May to 1 June 1916, off the North Sea coast of Denmark's Jutland Peninsula. It was the largest naval battle and only full-scale clash of battleships of the war, and the outcome ensured that the Royal Navy denied the German surface fleet access to the North Sea and the Atlantic for the remainder of the war, as Germany avoided all fleet-to-fleet contact thereafter. Jutland was also the last major naval battle, in any war, fought primarily by battleships.
Germany's High Seas Fleet intended to lure out, trap, and destroy a portion of the British Grand Fleet, as the German naval force was insufficient to openly engage the British fleet. This was part of a larger strategy to break the British blockade of Germany and allow German naval vessels access to the Atlantic. Britain's Royal Navy pursued a strategy of engaging and destroying the High Seas Fleet, thereby keeping German naval forces contained and away from Britain and her shipping lanes. The Germans planned to use Vice-Admiral Franz Hipper's fast scouting group of five modern battlecruisers to lure Vice-Admiral Sir David Beatty's battlecruiser squadrons into the path of the main German fleet. They stationed submarines across the likely routes of the British ships. However, the British learned from signal intercepts that a major fleet operation was likely, so on 30 May, Jellicoe sailed with the Grand Fleet to rendezvous with Beatty, passing over the German submarine picket lines while they were unprepared. The German plan had been delayed, causing further problems for their submarines, which had reached the limit of their endurance at sea.
On the afternoon of 31 May, Beatty encountered Hipper's battlecruiser force before the Germans had expected. Hipper successfully drew the British vanguard into the path of the High Seas Fleet. By the time Beatty sighted the larger force and turned back towards the British main fleet, he had lost two battlecruisers, from a force of six battlecruisers and four battleships. Beatty's withdrawal at the sight of the High Seas Fleet, which the British had not known were in the open sea, reversed the battle by drawing the Germans towards the British Grand Fleet. Between 18:30, when the sun was lowering, back-lighting the German forces, and nightfall at 20:30, the two fleets—totalling 250 ships—directly engaged twice. Fourteen British and eleven German ships sank, with a total of 9,823 casualties. After sunset Jellicoe manoeuvred to cut the Germans off from their base, hoping to continue the battle the next morning, but under the cover of darkness Scheer broke through the British light forces forming the rearguard of the Grand Fleet and returned to port.
Both sides claimed victory. The British lost more ships and over twice as many sailors but succeeded in containing the German fleet. The British press criticised the Grand Fleet's failure to force a decisive outcome, while Scheer's plan of destroying a substantial portion of the British fleet failed. The British long-term strategy of denying Germany access to the United Kingdom and Atlantic succeeded. The Germans' "fleet in being" continued to pose a threat, requiring the British to keep their battleships concentrated in the North Sea, but the battle reinforced the German policy of avoiding all fleet-to-fleet contact. At the end of 1916, after further unsuccessful attempts to reduce the Royal Navy's numerical advantage, the German Navy accepted its surface ships had been successfully contained, turning its resources to unrestricted submarine warfare for the second time (the first attempt of the war having ended with the controversy following the sinking of the RMS Lusitania) and destruction of Allied and neutral shipping, which—with the Zimmermann Telegram—by April 1917 triggered the United States of America's declaration of war on Germany. Reviews by the Royal Navy generated disagreement between supporters of Jellicoe and Beatty concerning their performance in battle; debate over this and the significance of the battle continues.

Background and planning.
German planning.
With 16 dreadnought-type battleships, compared with the Royal Navy's 28, the German High Seas Fleet stood little chance of winning a head-to-head clash. The Germans therefore adopted a divide-and-conquer strategy. They would stage raids into the North Sea and bombard the English coast, with the aim of luring out small British squadrons and pickets, which could then be destroyed by superior forces or submarines.
In January 1916, Admiral von Pohl, commander of the German fleet, fell ill. He was replaced by Scheer, who believed that the fleet had been used too defensively, had better ships and men than the British, and ought to take the war to them. According to Scheer, the German naval strategy should be:
 ;templatestyles src="Template:Blockquote/styles.css" / ;to damage the English fleet by offensive raids against the naval forces engaged in watching and blockading the German Bight, as well as by mine-laying on the British coast and submarine attack, whenever possible. After an equality of strength had been realised as a result of these operations, and all our forces had been made ready and concentrated, an attempt was to be made with our fleet to seek battle under circumstances unfavourable to the enemy.
On 25 April 1916, a decision was made by the German Imperial Admiralty to halt indiscriminate attacks by submarines on merchant shipping. This followed protests from neutral countries, notably the United States, that their nationals had been the victims of attacks. Germany agreed that future attacks would only take place in accord with internationally agreed prize rules, which required an attacker to give a warning and allow the crews of vessels time to escape, and not to attack neutral vessels at all. Scheer believed that it would not be possible to continue attacks on these terms, which took away the advantage of secret approach by submarines and left them vulnerable to even relatively small guns on the target ships. Instead, he set about deploying the submarine fleet against military vessels.
It was hoped that, following a successful German submarine attack, fast British escorts, such as destroyers, would be tied down by anti-submarine operations. If the Germans could catch the British in the expected locations, good prospects were thought to exist of at least partially redressing the balance of forces between the fleets. "After the British sortied in response to the raiding attack force", the Royal Navy's centuries-old instincts for aggressive action could be exploited to draw its weakened units towards the main German fleet under Scheer. The hope was that Scheer would thus be able to ambush a section of the British fleet and destroy it.
Submarine deployments.
A plan was devised to station submarines offshore from British naval bases, and then stage some action that would draw out the British ships to the waiting submarines. The battlecruiser had been damaged in a previous engagement, but was due to be repaired by mid-May, so an operation was scheduled for 17 May 1916. At the start of May, difficulties with condensers were discovered on ships of the third battleship squadron, so the operation was put back to 23 May. Ten submarines—, , , , , , , , , and —were given orders first to patrol in the central North Sea between 17 and 22 May, and then to take up waiting positions. "U-43" and "U-44" were stationed in the Pentland Firth, which the Grand Fleet was likely to cross when leaving Scapa Flow, while the remainder proceeded to the Firth of Forth, awaiting battlecruisers departing Rosyth. Each boat had an allocated area, within which it could move around as necessary to avoid detection, but was instructed to keep within it. During the initial North Sea patrol the boats were instructed to sail only north–south so that any enemy who chanced to encounter one would believe it was departing or returning from operations on the west coast (which required them to pass around the north of Britain). Once at their final positions, the boats were under strict orders to avoid premature detection that might give away the operation. It was arranged that a coded signal would be transmitted to alert the submarines exactly when the operation commenced: "Take into account the enemy's forces may be putting to sea".
Additionally, "UB-27" was sent out on 20 May with instructions to work its way into the Firth of Forth past May Island. "U-46" was ordered to patrol the coast of Sunderland, which had been chosen for the diversionary attack, but because of engine problems it was unable to leave port and "U-47" was diverted to this task. On 13 May, "U-72" was sent to lay mines in the Firth of Forth; on the 23rd, "U-74" departed to lay mines in the Moray Firth; and on the 24th, "U-75" was dispatched similarly west of the Orkney Islands. "UB-21" and "UB-22" were sent to patrol the Humber, where (incorrect) reports had suggested the presence of British warships. "U-22", "U-46" and "U-67" were positioned north of Terschelling to protect against intervention by British light forces stationed at Harwich.
On 22 May 1916, it was discovered that "Seydlitz" was still not watertight after repairs and would not now be ready until the 29th. The ambush submarines were now on station and experiencing difficulties of their own: visibility near the coast was frequently poor due to fog, and sea conditions were either so calm the slightest ripple, as from the periscope, could give away their position, or so rough as to make it very hard to keep the vessel at a steady depth. The British had become aware of unusual submarine activity, and had begun counter-patrols that forced the submarines out of position. "UB-27" passed Bell Rock on the night of 23 May on its way into the Firth of Forth as planned, but was halted by engine trouble. After repairs it continued to approach, following behind merchant vessels, and reached Largo Bay on 25 May. There the boat became entangled in nets that fouled one of the propellers, forcing it to abandon the operation and return home. "U-74" was detected by four armed trawlers on 27 May and sunk south-east of Peterhead. "U-75" laid its mines off the Orkney Islands, which, although they played no part in the battle, were responsible later for sinking the cruiser carrying Lord Kitchener, the Secretary of State for War on 5 June, killing him and all but 12 of the crew. "U-72" was forced to abandon its mission without laying any mines when an oil leak meant it was leaving a visible surface trail astern.
Zeppelins.
The Germans maintained a fleet of Zeppelins that they used for aerial reconnaissance and occasional bombing raids. The planned raid on Sunderland intended to use Zeppelins to watch out for the British fleet approaching from the north, which might otherwise surprise the raiders.
By 28 May, strong north-easterly winds meant that it would not be possible to send out the Zeppelins, so the raid again had to be postponed. The submarines could only stay on station until 1 June before their supplies would be exhausted and they had to return, so a decision had to be made quickly about the raid.
It was decided to use an alternative plan, abandoning the attack on Sunderland but instead sending a patrol of battlecruisers to the Skagerrak, where it was likely they would encounter merchant ships carrying British cargo and British cruiser patrols. It was felt this could be done without air support, because the action would now be much closer to Germany, relying instead on cruiser and torpedo boat patrols for reconnaissance.
Orders for the alternative plan were issued on 28 May, although it was still hoped that last-minute improvements in the weather would allow the original plan to go ahead. The German fleet assembled in the Jade River and at Wilhelmshaven and was instructed to raise steam and be ready for action from midnight on 28 May.
By 14:00 on 30 May, the wind was still too strong and the final decision was made to use the alternative plan. The coded signal "31 May G.G.2490" was transmitted to the ships of the fleet to inform them the Skagerrak attack would start on 31
