K Parker: The Escapement

"Good. New orders. You need to bring down your elevation fourteen minutes, all of you."

The captain was doing mental arithmetic. "That can't be right," he said. "If we do that, we'll be shooting straight at-"

"Fourteen minutes," the Ducas repeated. "Now." The parts of a machine fulfil their various functions because they have no choice. A lever pivots a sear, which slips out of the notch cut in the underside of a roller. Unsupported, the roller gives way, releasing the slider, which shoots forward under the pressure of two springs along a close-sided keyway, driving the arrow shaft along its channel and away through the air. The arrow has no choice but to fly until it hits the target. Or a lever pivots a sear, which slips out of its notch in the roller, which releases the swinging arm, which rushes through ninety degrees, pivoting around its axis pin, until it slams into the crossbar, launching a net full of bricks, broken masonry, flints and potsherds into the air. Then the hook goes on the slider or the arm and the winch begins to turn. The tongue dances over the teeth of the ratchet as each turn drags back the slider or the arm against the furious resistance of the springs, until the sear drops into the notch on the underside of the roller, and a new arrow or a new consignment of lethal junk lands in the slot, and the lever drops, and the sear falls out. Between the spanning of the spring and the release there is only the sear, the trigger, the escapement, and once it lets go, the force is committed beyond recall.

Then the scorpion bolts lift, like a flock of rooks disturbed while feeding; they climb into the air on a lifting curve that reaches a high point, hesitates for a tiny moment, then (as though a sear has been tripped) falls in a decaying trajectory, accelerating as it slants down out of the sky. Or the hundredweight of jumbled, ballistically inefficient rubbish soars in a dissipating pattern, hangs, decays and drops, each lump spinning and twisting in the air like a falling man treading emptiness, powered by its own height and the furious pull of the ground, until it pitches… Miel Ducas had seen it all before, of course. Once upon a time, he'd watched the Mezentine artillery beat flat the Eremian army, the way the wind lays a field of corn. Once you've seen one wipeout, there's a case for saying you've seen them all. So it didn't bother him that he couldn't see what happened after the cloud of bolts lifted up into the sky. He could picture it in his mind easily enough.

Instead, he watched the Vadani cavalry pouring down over the ridge, parting into two wings as it reached the plain and surging up to surround the remaining four fifths of the Aram Chantat as they waited still and quiet for their shifts to begin. Of course, they couldn't see what was happening on the other side of the bank that shielded the artillery from the city batteries. They wouldn't have the faintest idea, until the scorpions swung round on their traverses to point straight at them.

Even so, he thought, it'd probably be a good idea to get out of the way. He walked his horse through the gap between the head-high stacks of scorpion bolts, dismounted, handed the reins to someone or other and scrambled up on to the wall, at a place where a Mezentine shot had punched a hole. What he saw was quite familiar.

"One more shot," he called out, "then a new setting."

This time, nobody questioned the order. The war council was still sitting, of course. There had been issues they wanted to discuss without General Vaatzes there. But the general came in anyway, and he had a platoon of Eremian soldiers with him.

"Your attention, please," he said. No choice at all, as he explained to them. A fifth of their men were already dead, shot or squashed by the combined fire of the Eremians and the Mezentines. The remainder were unarmed, packed close together, surrounded on three sides by the Vadani cavalry and faced on the fourth side by the allied scorpion batteries. As Ziani pointed out, if they chose to fight, there was a chance they might prevail by sheer force of numbers, eventually, but their losses would be something of the order of seventy per cent; and then they'd still have the Mezentines to contend with.

"I arranged it with Duke Valens and Chairman Psellus," he went on. He was almost too tired to speak, but the impetus of the final stage swept him along. "We all agreed that, compared with the threat you represent, our differences are relatively trivial; the sort of things we can always sort out later on, we decided, once we've got rid of you."

They were staring at him, but he really couldn't care less about that. His mind was a long way away, preoccupied with far more important issues.

"At any rate," he went on, "we've solved the supply problem-which," he added with a grin, "I created when I told Daurenja how to blow up the embankment. It was my gesture of good faith to Chairman Psellus; by using up a third of our flour reserve, I guaranteed to him that the City couldn't be taken by conventional siege and assault, because there simply wouldn't be time before our supplies ran out. He had to take my word for it that General Daurenja's secret weapon wouldn't work, but that was a foregone conclusion. I was there when it was made, and I knew it would fail. Now, of course, the supply problem's been solved, simply by virtue of the fact that there's eighty thousand less of you and twenty thousand fewer Mezentines. It was a brutal solution, but rather less so than the alternative, which was to slaughter all the Mezentines. And if you discounted that, there really wasn't any choice."

He paused for breath. He'd been talking quickly, to get it over with so he could move on. He slowed down a little as he continued:

"My deal with Psellus is as follows. We-I mean the Vadani and the Eremians-will disarm you and escort you over the mountains to the edge of the desert. Once you've crossed back to where you came from, Mezentine engineers will destroy the string of oases, so no one will ever be able to bring an army across there again." He shrugged. "I have no idea how you go about wrecking a large pool of water, but my people have the expertise, not to mention the incentive. Then, apart from the inevitable small raiding parties every so often, we'll never see or hear from you again, which is how it should be. The Mezentines will break down the City walls and undertake never to raise a standing army; and there'll be a trade agreement, we haven't worked out any details yet, but it'll mean the Mezentines will sell their goods for a fair price, and pay a substantial war indemnity; there'll also be a lot of changes in the way the Republic's run, but that's an internal matter, nothing to do with you. In return, the Vadani and the Eremians will be responsible for the City's defence." He frowned. "It's not a very good deal for any of us, and I expect it'll break down sooner or later and we'll all be back at each other's throats again before very long, but at least we'll be rid of you. It took this war to make us all realise that you're the one problem none of us can accommodate. You're a different kind of threat; you change everything."

One of the Aram Chantat said: "You realised it, though. Before the wedding, even. That's why you made it happen."

Ziani gave him a blank stare. "I'm not important," he said. "What possible relevance could one man's concerns have to the fate of nations? What I've done is end the war with the minimum of bloodshed and damage, and given the people of three countries some kind of chance of living in peace. Surely that's a leader's duty, and if it isn't, it should be."

"We misjudged you," said another. "We assumed you wanted revenge."

"I'm not a savage," Ziani replied calmly. "Only savages think like that."

He was about to dismiss them, but one of the Aram Chantat caught his eye and said, "Will you go back to your wife and daughter, and your work in the factory? Isn't that what you wanted?"
