During the rest of the year of 1914 no further sea fight took place in the North Sea nor was there any serious loss to the navy from torpedo or submarine. But on the first of January, 1915, the British ship Formidable, 15,000 tons, was struck by two torpedoes and sunk. The previous day she had left Sheerness with eight vessels of the Channel fleet and with no protection from destroyers. The night was a bright moonlight and for such vessels to be moving in line on such a night without destroyers shows gross carelessness. Out of a crew of 800 men only 201 were saved, and the rescue of this part of the crew was due to the seamanship of Captain Pillar of the trawler Providence, who managed to take most of those rescued on board his vessel.
On January 24th the German battle cruiser squadron under Rear-Admiral Hipper set sail from Wilhelmshaven. What his object was is not known. He had enlarged the mine field north of Helgoland and north of the mine field had stationed a submarine flotilla. It is likely that he was planning to induce the British fleet to follow him into the mine field, or within reach of his submarines. That same morning the British battle cruiser squadron under Vice-Admiral Sir David Beatty put to sea.
According to the official report of the English Admiral he was in command of the following vessels; battle cruisers, the Lion, Princess Royal, the Tiger, the New Zealand, and the Indomitable; light cruisers, the Southampton, the Nottingham, the Birmingham, the Lowestoft, the Arethusa, the Aurora and the Undaunted, with destroyer flotillas under Commodore Tyrwhitt. The German Admiral had with him the Seydlitz, the Moltke, the Derfflinger, the Blucher, six light cruisers and a destroyer flotilla. The English Admiral apparently had some hint of the plans of the German squadron. The night of the 23d had been foggy; in the morning, however, the wind came from the northeast and cleared off the mists. An abridgment of the official report gives a good account of the battle, sometimes called the battle of Dogger Bank:
"At 7.25 A. M. the flash of guns was observed south-southeast; shortly afterwards the report reached me from the Aurora that she was engaged with enemy ships. I immediately altered course to south-southeast, increased speed, and ordered the light cruisers and flotillas to get in touch and report movements of enemy. This order was acted upon with great promptitude, indeed my wishes had already been forestalled by the respective senior officers, and reports almost immediately followed from the Southampton, Arethusa, and Aurora as to the position and composition of the enemy. The enemy had altered their course to southeast; from now onward the light cruisers maintained touch with the enemy and kept me fully informed as to their movements. The battle cruisers worked up to full speed, steering to the southward; the wind at the time was northeast, light, with extreme visibility.
"At 7.30 A. M. the enemy were sighted on the port bow, steaming fast, steering approximately southeast, distance fourteen miles. Owing to the prompt reports received we had attained our position on the quarter of the enemy, and altered course to run parallel to them. We then settled down to a long stern chase, gradually increasing our speed until we reached 28.5 knots.
"Great credit is due to the engineer staffs of the New Zealand and Indomitable. These ships greatly exceeded their speed. At 8.52 A. M., as we had closed within 20,000 yards of the rear ship, the battle cruisers maneuvered so that guns would bear and the Lion fired a single shot which fell short. The enemy at this time were in single line ahead, with light cruisers ahead and a large number of destroyers on their starboard beam. Single shots were fired at intervals to test the range, and at 9.09 the Lion made her first hit on the Blucher, the rear ship of the German line. At 9.20 the Tiger opened fire on the Blucher, and the Lion shifted to the third in the line, this ship being hit by several salvos. The enemy returned our fire at 9.14 A. M., the Princess Royal, on coming into range, opened fire on the Blucher. The New Zealand was also within range of the Blucher which had dropped somewhat astern, and opened fire on her. The Princess Royal then shifted to the third ship in the line (Derfflinger) inflicting considerable damage on her. Our flotilla cruisers and destroyers had gradually dropped from a position, broad on our beam, to our port quarter, so as not to foul our range with their smoke. But the enemy's destroyers threatening attack, the Meteor and M division passed ahead of us.
"About 9.45 the situation was about as follows: The Blucher, the fourth in their line, showed signs of having suffered severely from gun fire, their leading ship and number three were also on fire. The enemy's destroyers emitted vast columns of smoke to screen their battle cruisers, and under cover of this the latter now appeared to have altered course to the northward to increase their distance. The battle cruisers therefore were ordered to form a line of bearing north-northwest, and proceeded at the utmost speed. Their destroyers then showed evident signs of an attempt to attack. The Lion and the Tiger opened fire upon them, and caused them to retire and resume their original course.
"At 10.48 A. M. the Blucher, which had dropped considerably astern of the enemy's line, hauled out to port, steering north with a heavy list, on fire, and apparently in a defeated condition. I consequently ordered the Indomitable to attack the enemy breaking northward. At 10.54 submarines were reported on the starboard bow, and I personally observed the wash of a periscope. I immediately turned to port. At 10.03 an injury to the Lion being reported as being incapable of immediate repair, I directed the Lion to shape course northwest.
"At 11.20 I called the Attack alongside, shifting my flag to her, and proceeded at utmost speed to rejoin the squadron. I met them at noon, retiring north-northwest. I boarded and hoisted my flag on the Princess Royal, when Captain Brock acquainted me with what had occurred since the Lion fell out of line, namely, that the Blucher had been sunk and that the enemy battle cruisers had continued their course to the eastward in a considerably damaged condition. He also informed me that a Zeppelin and a seaplane had endeavored to drop bombs on the vessels which went to the rescue of the survivors of the Blucher."
It appears from this report that as soon as the Germans sighted the British fleet they promptly turned around and fled to the southeast. This flight, before they could have known the full British strength, suggests that the German Admiral was hoping to lure the British vessels into the Helgoland trap. The British gunnery was remarkably good, shot after shot taking effect at a distance of ten miles, and that too when moving at over thirty miles an hour. Over 120 of the crew of the Blucher were rescued and more would have been rescued if it had not been for the attack upon the rescue parties by the German aircraft. The injury to the Lion was very unfortunate. Admiral Beatty handed over charge of the battle cruisers to Rear-Admiral Moore, and when he was able to overtake the squadron he found that under Admiral Moore's orders the British fleet were retiring. The British squadron at the moment of turning was seventy miles from Helgoland, and in no danger from its mine fields. What might have been a crushing victory became therefore only a partial one: the Germans lost the Blucher; the Derfflinger and the Seydlitz were badly injured, but it seems that with a little more persistence the whole German squadron might have been destroyed.
