The M.-L.'s were at the tail of the flotilla. Their rôle would come last. It was imperative that they should be preserved intact until the critical moment. Their motors had to be kept absolutely in tune, for engine trouble meant disaster, not only to the crippled M.-L., but possibly to her consorts. An hour and a half sped. Slowly, yet in perfect order, the strange assembly of warships lessened the distance between them and the invisible Belgian coast. Already the glare of the hostile search-lights could be discerned. "Another three hours, my lad, and we'll be seeing life," declared Farnborough; "and death," he added in an undertone. Almost as he spoke, a general wireless signal was sent from the Flagship. Decoded, the orders were brief and explicit: "Operations abandoned owing to adverse weather conditions. Ships to return to Dover." CHAPTER XI The Lone Air-Raider Apart from the actual fact that he was a prisoner, Alec Seton's captivity on the Mole at Zeebrugge was far from irksome. He had an almost uninterrupted view of the interior of the harbour, and seaward his range of vision in clear weather embraced a wide arc of the horizon. So confident were the Huns of the impossibility of Seton's escape that they allowed him to see almost everything that was going on, his gaolers actually pointing out various details, and gloating over the effects upon their prisoner. It was only when a bombardment or a raid was expected that the seaward window, or rather aperture, was closed. This was effected by lowering a heavy slab of metal, after the fashion of an old-time gun-port. It was a precaution against signalling on the part of the captive. But without light or matches, or even a looking-glass as a heliograph, it was difficult to see how Seton could have accomplished the feat. His food was poor and meagre. This was hardly the fault of the Huns, since the admirable blockade by the Allied fleets had already reduced Germany to the verge of starvation. Generally speaking, the demeanour of his guards was harsh and tyrannical. Misled by their officers, the rank and file of the Boche armies believed that Germany was already within measurable distance of emerging triumphant from the world-wide contest. This, to a great extent, explained the domineering manner of Seton's guards, although there were some who, guessing the truth, bore in mind possible consequences should the relative positions of captor and captive be reversed.
