The latest of these, the "Derfflinger," was launched at Hamburg in 1914. On the outbreak of war, she was actually performing her trials, and was no doubt hurriedly completed and commissioned. She is distinguishable by the fact that all her turrets are in the centre line, an arrangement that enables the majority of her guns to fire a broadside to either flank. The main battery consists of eight 12-inch guns. The turbine engines are of the very latest pattern, and are designed for a speed of twenty-seven knots.
The "Seydlitz," a slightly larger edition of the "Moltke" and the "Goeben," is in a class by herself. She has about the same speed as the "Derfflinger," but is not so heavily armed, her largest guns not being greater than 11-inch weapons--a calibre that is unknown on board the ships of the British Navy. As far as can be ascertained, the "Seydlitz" cannot be regarded as a complete success. By reason of her great speed, her heavy batteries and thick armour belt, she consumes, when travelling at her utmost speed, an amazing amount of fuel, which could not easily be replaced if the ship were operating in distant seas.
The "Moltke" is the sister-ship of the famous "Goeben," which succeeded in escaping from the Mediterranean squadron at the beginning of the war, seeking refuge in the Bosphorus, where she hoisted the Turkish ensign. The "Moltke" was launched at Hamburg in 1910, and is considerably faster than either the "Seydlitz" or the "Derfflinger"--which can be accounted for by the fact that she is not so heavily armoured.
The last ship of the squadron, the "Blücher," is, for more reasons than one, likely to be of the greatest interest to English readers; firstly, because of the fate with which she met, and secondly, because of her history.
In the year 1908, it was known in German Naval circles that the British Admiralty was building a new class of ship, which was to combine something of the heavy batteries and armour-plate protection of a battleship with the speed of a first-class cruiser. The designs of these ships--which are now known as the "Invincible" class--were kept wholly secret; and beyond the fact that they were likely to prove a kind of combination of the Dreadnought and the cruiser, nothing concerning the details of their construction was known either at Hamburg or at Kiel.
It was none the less necessary for the German naval authorities to design and construct some kind of ship capable of holding its own against the British "Invincibles"; and the "Blücher" was the result.
It must be confessed--even by the most patriotic Junkers that ever swaggered in Unter den Linden--that she was a failure. When launched, the ship was found to be very greatly inferior to its British rivals. The "Blücher" carried twelve 8.2-inch guns as against the eight 12-inch guns of the "Invincible." Her top speed was also a good knot an hour less than that which could be accomplished by the British ships, in spite of the fact that she was no better protected and was even more expensive in regard to fuel. It is, indeed, doubtful whether this ship can rightly be called a "battle cruiser," though--to her cost--she was included in the German battle-cruiser squadron that set forth from the Bight of Heligoland, on the morning of January 24, to raid the English coast.
All these ships have a most formidable appearance. Combining, as they do, great strength with maximum speed, they are enemies not to be despised. They appear even more powerful than they are, since all lie low in the water and have enormous, stumpy funnels from which the black smoke rolls in clouds.
Captain Crouch, who was well acquainted with the ships of the German Navy, recognized them the moment he brought his telescope to bear in their direction, and saw at once the extreme danger of the situation. The German cruisers, steering due north-west, were making straight for the "Mondavia," which was already within range of the great 11-inch guns. Flight would be altogether useless, since the men-of-war were travelling at, at least, twice the pace of the tramp. Moreover, to turn back would be doubly fatal, since this would bring the "Mondavia" within range of a torpedo discharged from the submarine.
Captain Crouch was not a man who took long to make up his mind. When it was necessary to act, to take the greatest risks, he never hesitated to do so. He may already have given himself up for lost, or else he may have thought that a small chance, one last hope, remained; in any case, he put the ship about, and steaming at full speed, made straight for the U93.
