Soon afterward, Lion lost her remaining dynamo to the rising water, which knocked out all remaining light and power. At 11:02, Beatty had flags hoisted signalling "course north-east", to bring his ships back to their pursuit of Hipper, and "attack the rear of the enemy". Rear-Admiral Sir Gordon Moore – temporarily commanding the squadron from – thought the signals meant to attack Blücher, which was about to the north-east, and ordered the four other battlecruisers away from the pursuit of Hipper's main force to engage. Beatty tried to correct the mistake, but he was so far behind the leading battlecruisers that his signals could not be read in the smoke and haze. Beatty transferred to the destroyer at 11:50 and set off in pursuit of his battlecruisers, reaching them shortly before Blücher sank. He boarded Princess Royal at 12:20 and ordered the ships to pursue the main German force. This order was rescinded when it became clear that the time lost in sinking Blücher meant the rest of Hipper's battlecruisers would reach friendly waters before they could be caught. Beatty's battlecruisers turned for home, catching up to Lion, which was limping along at . Princess Royal hit Derfflinger once, but only damaged two armour plates and caused a coal bunker to flood. She hit Blücher at least twice, including the shot that crippled her, out of a total of 271 shells fired during the battle, a hit rate of only 0.7%. By way of contrast, her sister made four hits out of 243 shells fired, a rate of 1.6%. She also fired two 13.5-inch shrapnel shells at the German airship L 5 as its crew attempted to bomb the sinking Blücher, mistaking it for a British ship, despite the fact that the maximum elevation of those guns was only 20°. Princess Royal was not damaged during the battle. Battle of Jutland On 31 May 1916, Princess Royal was flagship of the 1st BCS under Beatty's overall command; they had put to sea with the rest of the Battlecruiser Fleet to intercept a sortie by the High Seas Fleet into the North Sea. The British had decoded the German radio messages, and left their bases before the Germans put to sea. Hipper's battlecruisers spotted the Battlecruiser Fleet to their west at 15:20, but Beatty's ships did not see the Germans to their east for another 10 minutes. At 15:32, Beatty ordered
