"Go and see what it is," said the admiral; "we must put out to sea with one engine." At that moment the chief engineer came up, looking white and scared, and said, in a low, shaking voice:

"Monsieur, the crank shaft of the starboard engine has splintered as though it had been made of glass. We are disabled!"

"Nom de Dieu!" exclaimed the admiral. "What is that you say?—disabled? and the tide setting in. Then we are lost. A few minutes will take us within range of the guns on the Canal and at Cuxhaven, and in an hour we may be ashore. There is no hope of repairs, I suppose?"

"Impossible, Monsieur l'Amiral. It would take weeks in the best dockyard in France to repair the damage."

"Then," said the admiral, turning to the commander, who was standing beside him, "we must do what we can. We will not be lost for nothing. Let everything be ready to return the fire of the forts as soon as we are within range."

By this time the German officers on the forts had noted with amazement, not unmixed with satisfaction, that some unaccountable accident had happened to the great French battleship. She was not under steam, she was not steering, she was simply drifting in with the tide as helplessly as a barrel. The tide was setting dead in towards the mouth of the Canal, and the commander of the great fort at Brunsbüttel, making certain of her surrender or destruction, ordered three of his heaviest guns, monsters capable of throwing a nine-hundred-pound shell to a distance of nearly fourteen miles, to prepare for action. They were mounted on disappearing carriages worked by hydraulic machinery.

The guns were already loaded, the mechanism was set in motion, and the giants rose slowly till their muzzles grinned over the glacis of the fort. Then, without any warning, the framework of one of the carriages cracked and splintered in all directions, the huge gun came back with a terrific crash on to the concrete floor of the emplacement, and, to the amazement of officers and gunners, broke into three pieces as if it had been made of glass instead of the finest steel that Krupp could produce.

Officers and men stared at each other in silent amazement. Were even the guns and their machinery affected by this strange languor which had been afflicting both men and animals for the last day or two? Instinctively they drew away from the other gun; but the Charles Martel was now well within range, and Colonel Von Altenau saw that it was his duty not to allow her to come any closer. In fact, he was almost surprised to see that she had not already opened fire upon the fort, so he ordered the centre gun to be trained on her and fired.

As the lanyard was pulled, those on board the battleship saw a vivid burst of flame, and the roar of an explosion came dully across the water, but no shell followed it. The admiral immediately came to the conclusion that some accident had happened in the fort, and he ordered his two forward 13-inch guns to send a couple of shells into it. He went into the conning-tower, and as soon as he received the signal that the guns were ready and laid, he pressed the electric button which should have sent the sparks through the charges. Nothing happened, and the guns remained silent.

Then he called down the speaking-tube connecting the conning-tower with the barbette:
