At the time of the Tondern raid, Von Butlar was flying from there, one of the two Zeppelins destroyed being that which he commanded. As he speaks little, if any, English, the following account is a free translation of the story he related to us in German of what occurred on that occasion. "We always recognized," he said, "from the time that we learned that the British were developing swift flying-machine carriers, that Tondern was especially vulnerable to an attack of this kind, and we prepared against it as best we could. We had expected, however, that it would come in the form of a raid by seaplanes, which would, of course, have been comparatively heavy and slow, and which would have had to return to the sea to land, and against these our defence would probably have been effective. Where we deceived ourselves was in underrating the risks that your men were willing to take, such as, for instance, that of landing in the sea in an ordinary aeroplane on the chance of being picked up in the comparatively short time such a machine will float."
"We were not prepared for such a raid at any time, but especially at the moment at which it occurred. We had had a protecting flight of light fighting aeroplanes at Tondern, but the landing ground had never been properly levelled. There had been many accidents, and a number of the machines were always disabled. This trouble became so bad toward the middle of last summer that it was finally decided to withdraw the protecting flight, which was badly needed at the moment elsewhere, until the landing ground had been improved. As usual, your Admiralty seem to have learned of this within a few hours and to have decided to take advantage of it at once. From the way your machines were flying when they appeared, I am practically certain that they felt sure of being opposed by nothing worse than gun-fire.
"We received warning, of course, when the raiding planes were still over the sea, but, unless some of the machines at once sent up from the coastal stations could stop them, there was nothing for us to do but to give them the warmest reception we could with the anti-aircraft guns, in which we were fairly strong. Our gunners were well trained, and if your planes had kept high, as they would have done if they had been expecting a strong attack by a superior force of protecting machines, they would most probably have been prevented from doing much harm, instead of just about wiping the station off the map, as they did.
"When we had the warning, most of those without special duties went to the abri, which had been provided at all stations for use in case of raids. But I was so concerned over the danger to my own ship that I remained outside. It was quite light by the time they appeared. At first they were flying high, but while they were still small specks I saw them begin to plane down, as though following a pre-arranged plan. It was all over in a minute or two after that. Part of them headed for one shed and part for the other. Diving with their engines all out—or so it seemed—they came over with the combined speed from their drop and the pull of their propellers. Down they came, till they seemed to be going to ram the sheds. Then, one after another, they flattened out and passed lengthwise over their targets at a height of about forty metres, kicking loose bombs as they went.
"Our guns simply had no chance at all with them. In fact, one of the guns came pretty near to getting knocked out itself. It was so reckless a piece of work that I couldn't help noticing it, even while my own airship was beginning to burst into flames. One of the pilots, it seems, must have found that he had a bomb or two left at about the same time he spotted the position of one of the guns that was firing at him. Banking steeply, round he came, dived straight at the battery, letting go a bomb as his sight came on when he was no more than fifteen metres above it. Then he waved his hand and dashed off after the other machines, which were already scattering to avoid the German planes beginning to converge on them from all directions. It was one of the finest examples of nerve I ever saw.
"The precaution we had taken of opening the doors of the main shed saved it from total destruction, for the airships, instead of exploding, only burned comparatively slowly; but Tondern, as an air station, had practically ceased to exist from that moment."

THROUGH THE CANAL TO THE BALTIC
The Hercules and her four escorting destroyers (the latter having been scattered during the last few days to various ports and air stations in connection with the inspection being pushed all along the German North Sea coast) were to have rendezvoused at Brunsbüttel by dark of the 10th, in order to be ready to start through the Kiel Canal at daybreak the following morning. At the appointed time, however, only the Viceroy, which had pushed through that morning with the "air" party en route to the Zeppelin station at Tondern, was on hand. The Hercules, which had got under weigh from Wilhelmshaven during the forenoon, reported that she had been compelled to anchor off the Elbe estuary on account of the thickness of the fog, and the Verdun, coming on from her visit to Borkum and Heligoland, had been delayed from a similar cause. The Vidette and Venetia, which were helping the "shipping" and "warship" parties get around the harbours of Bremen and Hamburg, signalled that their work was still uncompleted and that they would have to proceed later to Kiel "on their own."
