The Battle of Jutland took place in the North Sea between the German High Seas Fleet and British Grand Fleet on the afternoon and evening of 31 May 1916, continuing sporadically through the night into the early hours of 1 June. The battle was the only direct engagement between the two fleets throughout World War I. The war had already been waged for two years without any major sea battle, and many of the people present did not expect that this patrol would end differently. Lack of experience still accounted for a number of mistakes by the combatants. The battle has been described in a number of phases, the last of which is the subject of this article.

Prelude The battle began when scouting battlecruiser forces of the two fleets met at around 1430 the first day. The British force of six battlecruisers and four fast battleships commanded by Vice-Admiral Sir David Beatty gave chase to five German battlecruisers commanded by Vice-Admiral Franz Hipper. The German ships set course back towards where they knew the main German fleet was waiting, planning to lead the British ships into a trap. Despite his numerical disadvantage, Hipper succeed in sinking two British battlecruisers during the chase. Once the German fleet came in sight, the British ships reversed course, now intending to lead the German fleet in pursuit of them back towards the main British fleet.

Despite minimal information, Admiral John Jellicoe managed to deploy his ships to good advantage across the path of the approaching German fleet, so that some success was gained in the short battle before the Germans in turn reversed course and withdrew. Vice-Admiral Reinhard Scheer was now in a difficult position, because his smaller force was cut off from Germany by the British fleet deployed across his escape route. He first attempted once again approaching the British positions, but was driven back. He then took up a position north west of the British, awaiting nightfall before making further attempts to escape.

Jellicoe declined to give chase to the German fleet after the second encounter because of the limited daylight remaining. He feared that the difficulties spotting and identifying ships in darkness would nullify his numerical advantage over the Germans, but was also confident that his deployment would prevent the Germans escaping past him in the night, and battle could be resumed the following day in conditions to his advantage. His battleships were redeployed from their battle line into closed up night cruising formation, with the battlecruisers deployed to his south west to prevent Germans passing south, and destroyers deployed behind the main fleet to intercept Germans passing to the north.

British ships had not trained for night action, but German ships had. The Germans had better searchlight control, using iris shutters which could rapidly switch on and off the light, star shell which could be fired over enemy ships to illuminate them without having to use a searchlight, which automatically presented a target for return fire. They used a system of coloured lights for recognition signals between ships, which the British could not duplicate, whereas the British used plain flashed morse signals, which the Germans were partly able to copy after once seeing them, giving some advantage when ships met. Scheer determined that his best chance was to pass the British fleet during the night.

German options Scheer had four main escape routes, which were known to both admirals. He could change course away from the British fleet to the north-east and take a route through the Skagerrak channel north of Jutland back to safety in the Baltic. Although this might avoid the British, it was the longest route and risked some of his damaged ships sinking before reaching harbour. Jellicoe discounted the route, because of these considerations but also because the other escape routes all lay to the south, and he could not guard both directions. The longer route might also allow his faster ships to catch up the following day should Scheer go that way. The next possibility was via a gap cleared through the middle of the minefields laid by both sides in the Heligoland Bight. Scheer had taken this route on the way out, but the uncertainties in knowing their precise position after the battle and locating the seaward end of the channel would make it risky as a return route.

The third choice was around the minefields to the North Frisian coast and thence east to the River Ems and Jade. This was but Jellicoe had a report of the German fleet heading west south west, which was the course for this route and it would take Scheer generally away from the British. Jellicoe believed this was the most likely route for the Germans to take, so set a course south at , faster than the German ships could manage, which should put him in a position to locate and overtake the German fleet at daylight. The shortest route of was via Horns Reef to the SSE, passing north of the minefields laid by both sides in the Heligoland Bight. It was this route which Scheer chose despite having to pass the British fleet. Although it was not Jellicoe's guess at Scheer's actions, he anticipated that the destroyers and cruisers spread out around his fleet would give warning should the Germans take this route and his general course would still allow him to intercept.Steel & Hart pp. 284–285

British deployment

The British moved into night formation at 2117. Sunset had been at 2000, with full darkness by 2100. The ships were travelling approximately SSE with the battleships in four columns apart which were intended to travel parallel courses in a compact block giving minimum opportunity for surprise torpedo attack. The western column comprised the Second Battle Squadron of eight ships commanded by Martyn Jerram. The next column one mile to the east was the Fourth Battle Squadron led by , Jellicoe's flagship. Vice-Admiral Doveton Sturdee on commanding the fourth division (a division of four ships being half a squadron of eight), was second in command of this squadron. The third column consisted of the First Battle Squadron commanded by Vice-Admiral Sir Cecil Burney from . Marlborough had been damaged by a torpedo but reported she could keep up with a speed of . This proved optimistic, with the result that the half-squadron 5th division maintained its allotted position, but Marlborough and the other three ships of the 6th division fell progressively behind. The Fifth Battle Squadron commanded from by Hugh Evan-Thomas of only three fast battleships ( having returned to port damaged after taking part in the initial battlecruiser action), took up a position between the two separating halves. At 2203 the 5th Battle Squadron reversed course for five minutes so as to fall back closer to Marlborough.Campbell p.274

The battlecruisers commanded by Beatty were stationed fifteen miles WSW of Iron Duke, which it was anticipated would put them in a good position to intercept German ships. Their position meant that at 2130–2200 they were positioned unbeknownst to either side ahead of and leading the German battlefleet.Bennett p.128

The British fleet included smaller vessels used for screening and scouting purposes. The first Light Cruiser Squadron (LCS) commanded by Commodore Edwyn Alexander-Sinclair and the third LCS commanded by Rear-Admiral Trevylyan Napier were ordered to accompany Beatty. William Goodenough's second Light Cruiser Squadron was stationed north of Burney's 1BS, behind the fleet.Bennett p. 128 The fourth LCS commanded by Commodore Charles Edward Le Mesurier was placed ahead of the fleet, and the Second Cruiser Squadron commanded by Rear-Admiral Herbert Heath was stationed east of the battleships.Campbell P.274

The destroyers attached to the fleet were ordered to take stations approximately five miles behind. Jellicoe stated he had three reasons for their placement: to guard against surprise attack by German torpedo boats, to attack any major German ships should they attempt to pass the fleet, and to keep the destroyers clear of major British ships. Jellicoe recognised that identifying ships in the dark was difficult and wanted to ensure there could be no confusion by keeping his destroyers away from the British capital vessels. However, his orders at the time failed to make clear to the destroyers the position of other British vessels, so that in fact considerable confusion did arise later when the destroyers encountered large vessels. Overall control of the destroyers was given to Commodore Hawksley on the light cruiser , but individual destroyer flotillas were inexperienced in joint operations, particularly at night. The principal weapon of the destroyer was the torpedo, and this was most effective if used in salvoes fired from several ships at once, making it hard for enemy ships to dodge every torpedo.

At 2205 the minelayer was detached from the fleet and ordered to lay her mines off Horns Reef, in anticipation that German ships might attempt to flee in that direction.Bennett p.129

German deployment The German fleet continued in a similar deployment to that which it had used during the day, a single column in line ahead. At 2125 Scheer ordered his fleet to a course of 142 degrees. SMS Westfalen was slow in responding, so Scheer issued an adjusted course of 137 degrees at 2146. Westfalen misinterpreted the signal and thus turned to 156 degrees, finally turning to 133 degrees as instructed at 2232. At 2300 the course to head directly for the Horns Reef light ship was set at 130 degrees and Westfalen had complied by 2320.

Scheer felt it inadvisable for the relatively weak II Battle Squadron of pre-dreadnought battleships to remain at the head of the German line, where they had ended up after the multiple course reversals of the day and they were ordered to move to the rear. The manoeuvre was delayed since at 2130 SMS Hannover now leading the pre-dreadnought squadron sighted four large ships ahead, and a light inadvertently showing on the mast of of the 2nd British Cruiser squadron. Once the British ships had passed ahead, the II squadron turned north at 2150 and took station at the rear at 2210. Progress of the whole line was delayed slightly by the repositioning so that it fell back more to the north of the British ships. Westfalen at the head of the 1st Battle Squadron now led the revised column of battleships, followed by the III Battle Squadron and then the pre-dreadnought II Battle Squadron.Tarrant pp. 204–205

The II Scouting Group of cruisers was placed ahead of the battleships, while the IV Scouting Group was similarly placed to starboard.Steel & Hart p. 288 The IV SG under Commodore Ludwig von Reuter mistook its position in the dark, so ending up on the port side of the battle line rather than starboard.Tarrant p.205, 211

The battlecruisers were ordered to take positions at the rear behind II Squadron, because of their severe battle damage. Admiral Hipper had been forced to leave his flagship SMS Lützow and had some trouble boarding another ship in the course of the battle. At 2115 he boarded SMS Moltke and again assumed command, initially mistakenly ordering the ships to move to the head of the column. Only SMS Seydlitz and Moltke could immediately comply: SMS Derfflinger had too many holes to travel at speed, and SMS Von der Tann needed to clean ash from her boilers forcing her to steam slowly. When Derfflinger and Von der Tann drew abreast of the flagship SMS Friedrich der Grosse, Scheer once again ordered them to the rear. The two joined the end of the German column, but Seydlitz and Moltke remained out of position initially ahead of the fleet and had to move independently through the British fleet.Steel & Hart pp. 288–289 Lützow proceeded southwards behind the fleet for the first couple of hours of the night at the best speed she could manage, seven knots, but eventually sank at 0145.Campbell p.276
