Fifth ship in the starboard British line from the _Vanguard_ lay the great battleship _Indefatigable_, after the four “Dreadnoughts” one of the four powerful units in the fleet. Four torpedoes were fired at her by the German destroyers; three of the four missed her, two of them only by a hair’s breadth, but the fourth cut through the steel net and caught her fairly abreast of the port engine-room, about the level of the platform deck. The Germans were using their very powerful 17.7-in. Schwartzkopf torpedo, fitted with net-cutters, and carrying a charge of 265 lb. of gun-cotton, the heaviest employed in any navy, and nearly a hundred pounds heavier than that of the largest British torpedo. The effect of the explosion was terrific. Though the _Indefatigable_ had been specially constructed to resist torpedo attack, her bulkheads were not designed to withstand so great a mass of explosive, and the torpedo breached the plating of the wing compartments, the wing passage, and the coal-bunker, which lay immediately behind it. The whole structure of the ship was shaken and much injured in the neighbourhood of the explosion, and water began to pour through the shattered bulkheads into the port engine-room. The pumps got to work, but could not keep the inrush down; the ship rapidly listed to the port side, and though “out collision mat” was ordered at once, and a mat got over the huge, gaping hole in the battleship’s side, the water continued to gain. Slipping her anchors, at the order of the Admiral, the _Indefatigable_ proceeded a few hundred yards with her starboard screw to the shelving, sandy beach of Society Bank, where she dropped aground. Had the harbour works at Rosyth been complete, the value of them to the nation at this moment would have been inestimable, for there would have been plenty of time to get her into the dock which was under construction there. But in the desire to effect apparent economies the works since 1905 had been languidly pushed. The calamities of the British fleet did not end with the torpedoing of the _Indefatigable_. A few seconds later some object drifting in the water, probably a mine--though in the confusion it was impossible to say what exactly happened--struck the _Resistance_ just forward of the fore barbette. It must have drifted down inside the torpedo nets, between the hull and the network. There was an explosion of terrific violence, which rent a great breach in the side of the ship near the starboard fore torpedo tube, caused an irresistible inrush of water, and compelled her captain also to slip his anchors and beach his ship. Two of the British battle squadron were out of action in the space of less than five minutes from the opening of fire. Already the shattered remnants of the German torpedo flotilla were retiring; a single boat was steaming off as fast as she had come, but astern of her four wrecks lay in the midst of the British fleet devoid of motive power, mere helpless targets for the guns.
