Shortly after the Germans had occupied Libau, Russia’s most southerly port in the Baltic, a certain mysterious submarine made her presence felt in the Mediterranean of the North. An official bulletin from Petrograd stated that the boat was British, and that she had sunk the pre-Dreadnought Pommern off Danzig on the 2nd July, 1915. The Censor in London removed the reference to the nationality of the submarine, but a little later it leaked out that E 9 had resumed operations and was responsible for the disaster. In reply to a question put by Commander Bellairs, Dr Macnamara answered that no official report had been transmitted to the Admiralty, “but from a semi-official communication received from the Russian Government it appears that the name of the officer referred to is Commander Max K. Horton, D.S.O.,” which statement was received with enthusiastic cheers by the House of Commons.

The Pommern was completed in 1907, and displaced 13,200 tons. She carried four 11–in. and fourteen 6.7–in. guns, and a crew of over seven hundred officers and men. The Pommern was the first German battleship to be sunk in the war. The coveted Order of St George (Fourth Class) was bestowed on the Commander by Tsar Nicholas. The German Government vigorously denied that a battleship had been lost, but

and all the contradictions in the world failed to resurrect the Pommern.

The energetic E boats did not remain in obscurity very long. In the following month the enemy endeavoured to secure naval control of the Gulf of Riga. Their first attempt, made on the 8th August with nine battleships, twelve cruisers, and a brave showing of torpedo-boats, was a complete failure. It was followed up eight days later by a more ambitious force. Favoured by heavy sea fog, the enemy cleared a channel through the mines and net defences at the entrance within forty-eight hours, and were then ready to penetrate farther. If we accept the assertion of the Russians, the Germans paid dearly for their adventure. Against their own losses of two gunboats and several torpedo craft they assessed those of the Germans at two cruisers, and eight torpedo-boats either sunk or badly damaged. In addition, the Moltke, a battle-cruiser, was torpedoed by E 1. She was not mortally wounded, and was towed back to harbour, where she remained until Beatty claimed her. The Huns gained nothing and lost much in this attempt to dominate the Gulf.

On the 19th August, 1916, Lieut.-Commander Robert R. Turner of E 23 attacked an enemy battleship. The vessel, a member of the Nassau family, the first type of Dreadnought to be built in a German yard, was powerfully armed with twelve 11–in., twelve 5.9–in., and sixteen 21–pdr. guns, in addition to half a dozen submerged torpedo-tubes. The displacement was 18,600 tons, and the speed 19–20 knots, but experts held that the class was a failure when compared with our own earlier Dreadnoughts.

The first torpedo fired by E 23 badly damaged the battleship. Of that there is not the slightest doubt. Five destroyers immediately went to her assistance. While these were engaged in escorting her, a second torpedo hit the target, and the officer in command of the submarine reported that he “believed she was sunk.” Then began a war of contradiction. The Germans stated that one of their submarines had attacked a British destroyer and a cruiser, both of which went down shortly afterward. They admitted that the submarine was rammed, but added the rider that she had returned to harbour ‘badly damaged.’ The question of the loss of a second U-boat was carefully hedged. “The statement can only be verified when all reports from our submarines are to hand”—an ingenious ruse. The report anent British losses was without foundation.

As in the above case, it is not always possible to ascertain the result of a shot. Many other instances of likely losses could be cited. A British submarine saw four battleships of the Kaiser class off the Danish coast. After making all ready to attack, the boat broke surface of her own accord owing to the exceedingly heavy swell. This terrible risk was run quite accidentally, but she got under again. Four torpedoes were discharged at a range of 4000 yards at the third ship in the line. Two explosions proved that the weapons had performed their tasks, and the commander was of opinion that the third and fourth ships had both been hit. He was about to verify his belief when a destroyer was heard racing in his direction, followed by others. For two hours they patrolled in search of the boat that had shot this ‘bolt from the blue.’ They failed to find her. Two depth charges nearly did, but not quite, and a sweep dragged ominously over her hull. Puzzle: Did the battleships founder? The Marineamt in Berlin knows but does not say. In fifty-one months of conflict British submarines successfully attacked forty-three enemy warships.

A British submarine, referred to in a Dutch official communication as C 55, was patrolling in the North Sea on the 27th July, 1917, when she picked up a German steamer. This was the Batavier II, of 1328 tons net, proceeding in the direction of Hamburg. The North Sea, or ‘German Ocean’ as those who dwell on its eastern fringe fondly call it, had not been darkened by a mercantile ship of that nationality for many long months, and even the Batavier II was British-built and had been captured from the Dutch. The submarine overhauled her, and after having sustained damage by gunfire, she was captured, her crew escaping in their boats. A prize crew took possession of the vessel and endeavoured to bring her to port. The idea had to be abandoned because she made so much water. The opening of her sea-cocks speedily sent her beneath the waves. Twenty-eight survivors of the steamer’s crew were subsequently landed at Texel.
