Fleet. At 6:20, Beatty's destroyer screen came into contact with the German torpedo boat V155. This began a confused 2-hour battle between the British destroyers and the German cruiser and destroyer screen, frequently at very close range. At the time of the first encounter, the Kaiser-class battleships were less than 10 miles away from the 6 British dreadnoughts; this was well within firing range, but in the darkness, neither British nor German admiral were aware of the composition of their opponents' fleets. Admiral Ingenohl, loathe to disobey the Kaiser's order to not risk the battlefleet without his express approval, concluded that his forces were engaging the screen of the entire Grand Fleet, and so 10 minutes after the first contact, he ordered a turn to port on a south-east course. Continued attacks delayed the turn, but by 6:42, it had been carried out. For about 40 minutes, the two fleets were steaming on a parallel course. At 7:20, Ingenohl ordered a further turn to port, which put his ships on a course for German waters. Bombardment of Yarmouth and Lowestoft The Kaiser-class ships took part in another raid on the English coast, again as support for the German battlecruiser force in I Scouting Group. The battlecruisers left the Jade Estuary at 10:55 on 24 April 1916, and the rest of the High Seas Fleet followed at 13:40. The battlecruiser struck a mine while en route to the target, and had to withdraw. The other battlecruisers bombarded the town of Lowestoft largely without incident, but during the approach to Yarmouth, they encountered the British cruisers of the Harwich Force. A short artillery duel ensued before the Harwich Force withdrew. Reports of British submarines in the area prompted the retreat of I Scouting Group. At this point, Admiral Reinhard Scheer, who had been warned of the sortie of the Grand Fleet from its base in Scapa Flow, also withdrew to safer German waters. Battle of Jutland Four of the ships participated in the fleet sortie that resulted in the battle of Jutland on 31 May–1 June 1916. The operation was a repeat of earlier plans that intended to draw out a portion of the Grand Fleet and destroy it. Kaiser, Kaiserin, Prinzregent Luitpold, and Friedrich der Grosse, Scheer's flagship, made up VI Division of III Battle Squadron. III Battle Squadron was the first of three battleship units; however, the König-class battleships of
