He listened intently while the threat posed by the New Men was explained to him, now and then—as had always been his habit—making notes in neat, crowded script. His manner was just as Toller had remembered it—precise and meticulous, a reassurance that there was no difficulty which could not be overcome by the orderly application of reason.
“There you have it,” Chakkell said to Zavotle. “What do you think of this notion of establishing permanently manned fortresses in the weightless zone?” He had disliked the idea of having to consult a lowly captain, but had acquiesced to Toller’s request and had even—an indication of how seriously he regarded the situation—invited Zavotle to be seated at the table with him. Now he was eyeing the newcomer critically, with something of the air of a schoolmaster eager to fault a pupil’s performance.
Zavotle sat very straight, aware that he was on trial, and spoke firmly. “It can be done, Majesty. In fact, it must be done—we have no other recourse.”
“I see. And what about attaching two balloons to one long gondola?”
“With respect to Lord Toller, I don’t like it, Majesty,” Zavotle said, glancing at Toller. “The gondola would have to be very long to accommodate two balloons, and I think there would be serious control problems.”
“So you would advocate using one monstrous balloon?”
“No, Majesty—that would introduce an entirely new set of difficulties. No doubt they could be overcome in time, but we have no time to spare.”
Chakkell looked impatient. “What then? Have you something in mind, captain, or do you content yourself with deciding what cannot be done?”
“I believe we should continue to use the size of balloon with which we are experienced,” Zavotle said, not losing his composure. “The sky fortresses should be built in sections, taken aloft in sections—and assembled in the weightless zone.”
Chakkell stared hard at Zavotle, his expression slowly changing to one of mingled astonishment and respect. “Of course! Of course! There is no other way to proceed.”
Toller felt a pang of vicarious pride as the new concept flooded his mind, bringing with it a series of giddy images. “Good man, liven,” he breathed. “I knew we had need of you—though my gut freezes when I think about the kind of labour involved. Even with the knowledge that he was well tethered a man would be powerfully distracted by the sight of thousands of miles of thin air below him.”
“Many would be quite unable to concentrate their minds,” Zavotle said, nodding, “but the work would be kept to the absolute minimum. I envisage circular sections held together by simple clamps and sealed with mastic. A fortress might be constructed of three such sections.”
“Before we concern ourselves with details, I must know how many of these sky fortresses will be needed,” Chakkell said. “The more I think about it the more doubts plague me about the feasibility of the entire scheme. If one neglects volume and treats the weightless zone as a flat disk midway between the worlds, there are millions of square miles to defend—and I fail to see how it can be done. Even if I had the resources of old Kolcorron at my disposal I would be unable to construct the number of fortresses required. A thousand, would you say? Five thousand?”
Zavotle looked at Toller, giving him the opportunity to reply, and Toller responded with a slight shake of his head. The objection expressed by the King seemed to him a valid one, and although he could tell by Zavotle’s unperturbed expression that an answer existed he was for the moment unable to deduce it by himself.
“Majesty, we are not required to defend the entire area of the zone,” Zavotle said. “The two worlds have a common atmosphere, but it is shaped like an hourglass, with a slender waist. Skyships have to remain close to the centre of that waist—in a narrow bridge of air, so to speak—and that is where we will wait for the Landers. I do not know how determined they will be to press ahead with their invasion, but when we destroy the first of their ships the others may try to pass us by at a safe distance. To do that they would need to venture so far outside the air bridge that their crews would lose consciousness and then they would asphyxiate.”
“I begin to form an affection for you, Zavotle,” Chakkell said, half-smiling. “So, how many fortresses would you say?”
“Not many, Majesty. Perhaps as few as ten or twelve in the initial phase, while we have the advantage of surprise; perhaps a hundred later on, if the Landers begin to introduce effective counter-measures.” Zavotle again glanced at Toller, obviously trying to draw him back into the discussion. “I cannot be more precise at this stage. Much depends on the distance at which we can spot an ascending ship, but—as Lord Toller will testify—the eye becomes abnormally keen in the high air. Much will also depend on the effective range of our weaponry, but my expertise in that field is minuscule compared to Lord Toller’s. Perhaps he should say…”
“Continue without me for the present,” Toller said comfortably, appreciating Zavotle’s motives. “I find your discourse both interesting and instructive.”
“Your Lord Toller,” Chakkell whispered to Zavotle, “is so sure of himself that he has no fear of gifted and promising subordinates. Now, I have another and more prosaic difficulty for your consideration—one I fear you will not be able to magic away so quickly.”
“Majesty?”
“It is many years since I controlled the production of the Migration fleet, but I recall very clearly that the only material light enough and strong enough for the manufacture of skyship envelopes is linen.” Chakkell paused and frowned, dispelling the trace of levity which had crept into the proceedings.
“You may not be aware of this, but the flax seeds we brought from Land have not taken well in the soil of Overland. Only a few acres here and there produce a useful crop, and much of the yield has already gone into airships which are currently in service. In your considered opinion, could the material of those airship envelopes be cut up and restitched to form skyship balloons?”
“No!” Toller and Zavotle spoke simultaneously, but once again Toller—whose reply had been a reflex—was at a loss for a constructive answer. He was reminded of the fact that Chakkell was not King because of an accident of birth, that he had a phenomenally detailed knowledge of those aspects of agriculture, manufacture and trade which were the true foundation of a nation’s power. And again he chose to remain silent, transferring all responsibility to Zavotle. He was both surprised and impressed when Zavotle responded with a calm smile.
“The balloons must be made from new, perfect material, Majesty,” he said, “but not many will be required. The ambush strategy devised by Lord Toller is a good one, and it is fortunate for us that, in the circumstances envisaged, balloons would be an encumbrance, a serious handicap.”
Chakkell’s frown deepened. “We seem to be parting company, Zavotle. What are you saying?”
“Majesty, we are talking about a new kind of warfare, but some ancient principles must prevail. It is essential for us to remain out of sight of the enemy for as long as possible, until he has blundered into our trap. That being the case, balloons —which are so huge that they can be seen for many miles in the purity of a weightless zone—would become a liability. The fortresses would function more efficiently without them.”
