The Escapement (59 page)

The discussion was interrupted by the arrival of a colonel of engineers from the general's staff, who wanted to know what the hold-up was. On being told the reason, he ordered the major to think of something, and left quickly.

At this point, someone remembered the chain.

Nobody knew what it was or what it had once been used for. They'd found it in the ruins of a burnt-out transport depot beside the Lonazep road, and the most popular theory was that the Mezentines had made it for their customers in the Old Country, part of the payment for the services of the mercenaries they'd hired for the attack on Civitas Eremiae. For some reason it had never got to Lonazep; instead, it had been left in a shed, as often happens to awkward consignments, until the war overtook it and deprived it of significance and purpose. General Daurenja had read about it in some report and ordered that it should be sent to Civitas Vadanis to be broken up for scrap; it was four hundred yards long, each link weighing fifty pounds, all steel, so hard a file could scarcely cut it. The problem of shifting it had been passed around the transport executive like a hot coal until the commander of an Aram Chantat infantry division, with a point to prove in some long-forgotten argument, undertook to see to it. He sent two regiments to the depot site, where his men struggled for five days with rollers and levers to lay the chain out in a straight line. Then the regiments lined up beside the chain, and on the word of command, each man bent down and lifted up one link. It took them two days to get the chain back to the camp, at which point the commander, who'd forgotten about his undertaking, reassigned the regiments to other duties.

The major wasn't keen on the idea. For one thing, there was the obvious problem of shifting the thing. Furthermore, there was the matter of the weight, which he anticipated would burden the oxen so much that they wouldn't be able to do the job they'd been brought there for. Also, how were the yokes to be attached to the chain, and who was going to lift it up while it was being attached? In any case, the chain was, by definition, not a rigid beam; if a flexible beam would suffice, they might as well use rope and have done with it.

By now, however, the idea of the chain had taken hold in the minds of the senior engineers, who started suggesting solutions to the problems he'd raised, disagreeing with each other and all shouting at once. Why not a flexible beam, they wanted to know; and the drovers, when this question was put to them, replied that they'd specified rigid beams because that was all they'd ever used, but for all they knew a flexible beam might work, though they wouldn't be held responsible if it didn't. The stockmen disagreed fundamentally among themselves on the weight issue, one faction maintaining that an extra hundredweight or so was nothing to a good ox, the other asserting that it'd take six hundred oxen just to pull the chain. Bringing the chain and lifting it was dismissed as a trivial concern, especially by the Vadani miners. The camp was overflowing with Aram Chantat, they said, who sat around all day doing nothing while brave Vadani dug in the trenches and got shot at. Let them do it, and make themselves useful for a change.

Faced with this difference of opinion, the major referred the matter to General Daurenja, who expressed deep concern that the issue hadn't been addressed earlier, deplored the fact that they were now severely behind schedule, and ordered the major to use the chain. Taking this order as his authority, the major sent for three regiments of the Aram Chantat and an additional hundred oxen.

It was now pitch dark, and every third man in the Aram Chantat contingent was issued with a lantern, so he could walk beside the chain-carriers and light the way. The shortest, straightest route was right through the middle of the camp, and the Mezentine observers on the embankment reported that the enemy were holding some kind of festival, involving a torchlight procession. This was taken as an indication that it would be a quiet night, and four of the five artillery batteries were allowed to stand down and go home.

Shortly after midnight, when the chain was finally in place and lashed securely to the yokes with requisitioned cart-reins, a small party of sappers slipped quietly into the trench, dragging behind them trolleys mounted with large spools for paying out rope. The Mezentines' attention, what there was of it, was concentrated on the lights of the presumed festival, so they weren't observed as they fed the rope ends through the pulleys attached to the stakes they'd planted and cemented in a few days earlier. They checked the pulleys were greased and running smoothly, then led the ropes back up the trench. One end they tied to the last link of the chain. The other went round the towing hitches bolted to the fronts of the worms.

There was a young Mezentine artilleryman, Lucazo Boerzes, a member in good standing of the Wiremakers', and for some reason (his motivation has not been recorded) he decided to climb down the embankment and creep up behind the trench bank to get a closer look at the enemy festival. Anticipating trouble, or maybe simply because he was the sort of young man who made the most of any opportunity to carry a weapon, he took with him his bow, a quiver of arrows and a sword. It was later remembered that he'd been an enthusiastic member of the lunchtime archery club, and had twice scored a verified hit. Crawling most of the way, he eventually reached the head of the trench, where he'd seen a large concentration of moving lights. He was bewildered to see a long column of cattle, and his first thought was that these animals were being driven off to be slaughtered, either as part of some Aram Chantat religious ceremony or to feed the festival-goers. As he came closer, however, he couldn't help noticing that the cows (he'd never left the City before in his life, and didn't appreciate the difference between an ox and a cow) were wearing collars, which were somehow attached to what he recognised as a naval blockading chain, designed to be stretched across the mouth of a harbour to prevent ships from entering. It was, in fact, the chain he himself had worked on—his shift had drawn the bar stock from which the links had been formed—and he was entirely at a loss as to how to account for it being there, when it should have been spanning a harbour mouth somewhere in the Old Country. Fortunately, there was plenty of light, although he himself was safely outside it and therefore to all intents and purposes invisible; he carefully worked himself in closer, and saw that the chain was connected to a series of ropes lying in the trench. He couldn't help noticing too a number of large and completely unfamiliar-looking machines, also with ropes attached to them.

It was at this point that Boerzes came to the conclusion that what he was looking at probably wasn't a festival at all, but something rather more sinister. He therefore crawled in closer still (according to the report; some commentators have found it hard to credit much of what follows), and actually climbed up the blind side of the nearest machine and looked inside for some clue as to its function and purpose. He saw (if the report is to be believed) a mechanism by which the weight of a heavy lead block suspended from a rope wound around a spindle turned a driveshaft connected to a gear train, which in turn drove a headstock to which were fixed four curved and twisted blades. From the shape and profile of these blades, he deduced in a sudden flash of insight that they were designed to cut and scoop earth. Furthermore, the sear that released the weight, allowing it to descend and thereby drive the mechanism, was connected to an elaborate system of wires and levers leading to a pressure point on the front of the machine, just above the tow-hitch; the implication being that when the machine crashed into a solid obstacle, such as a bank of earth, the weight would be tripped and the blades would start to turn, without the need of a human operator.

At this point (so the report states) Boerzes found himself torn between his perceived duty and his personal desire to engage the enemy and single-handedly thwart what he recognised as an entirely viable plan to breach the bank of the flooded ditch and thereby drain it. Again, his true motivation can only be guessed at; the report records that he settled himself on the top of the machine, nocked an arrow on his bowstring and started shooting.

If this is indeed what happened, it's easy to imagine the bewilderment and panic it caused. It's entirely plausible that the drovers and sappers believed they were being attacked by a sortie in force from the embankment. Allied accounts of the incident confirm the Mezentine report's assertion that at least one of Boerzes' arrows hit an ox, which shied, broke its traces and plunged into the crowd of sappers and lantern-bearers. Many of them understandably sought the nearest cover, some of them crowding behind the worms; Boerzes asserted that, having by this time run out of arrows, he killed two of them with his sword before making his escape back to the Mezentine lines. In any event, the allies halted their operations, and Boerzes, having made a frantic report to the watch captain, urged him to start an artillery bombardment at once, to smash down the posts cemented in at the foot of the trench.

The watch captain pointed out that most of the artillery crews had been sent home, and the only men available were partially trained general infantry, incapable of working the engines, let alone aiming with sufficient precision to take out the posts. Instead, having sent a message to Chairman Psellus, he took the decision to launch a sortie with the forces at his command.

Psellus' reply, forbidding him to leave his position under any circumstances, came too late, and the sortie, no more than sixty men strong, scrambled down the embankment into the flooded ditch. Since none of them had been trained to swim in armour, it was inevitable that a number of them soon got into difficulties and were drowned; others were saved by their fellows or managed somehow to get across, but the commotion they made soon drew the attention of the allied sappers, who by now had realised that they were no longer under attack and were hurrying to get the operation back on schedule.

The surviving members of the sortie, meanwhile, had reached the trench; but they were leaderless, the captain having drowned in the flooded ditch, and most of them had only a very vague idea of what the purpose of the sortie was supposed to be. Instead of breaking down the posts or cutting the ropes, they advanced slowly and warily up the trench, apparently expecting to meet a raiding party of allied infantry. Instead, they met the worms. General Daurenja, directing this stage of the operation in person, had given the order for the oxen to be led forward, pulling on the ropes fed through the pulleys at the far end of the trench and thereby drawing the worms on their wheeled carriages down the trench towards the already weakened wall of the flooded ditch. The sortie took them for some kind of siege tower and, displaying a remarkable degree of courage in the circumstances, charged them and clambered aboard. Instead of finding them full of armed men, however, they quickly realised they were unmanned, and moving at a slow but steady rate towards the ditch. The sortie's nerve finally broke; they jumped down behind the worms, still not having the wit to cut the ropes, and tried to climb out of the trench over the gabion wall. In the dark, however, they had no idea how tall it was; they appeared to have concluded that it was too high to scale without ladders, and dropped back into the trench; for some reason, it didn't seem to have occurred to them to try the other side, where there was no wall and they could have scrambled out relatively easily. As a result, they were still in the trench when the worms hit the bank and set off their blade-spinning mechanisms.

Ziani Vaatzes had of course tested a prototype before shipping the worms to the camp; it helped, as well, that the weight of the ditch-water was pressing in from the other side. Even so, the speed and efficiency with which they bored through the bank surprised everybody, including the general. The bank collapsed and the water flooded out into the trench, sweeping before it a tumbled mess of gabions, shield trolleys, fascines and other equipment. Most probably it was the debris, rather than the floodwater, that accounted for the Mezentines in the trench; only six of them escaped to report back to Psellus on the embankment. The worms, on the other hand, remained firmly tethered to the posts, cemented into the trench floor, and when the water had drained away and the first allied troops arrived at the foot of the trench, they found them substantially intact, ready for use in the next stage of the operation.

Psellus' head was still full of sleep as they bundled him, in his frayed nightgown and slippers, into the Guildhall yard, where a covered sedan chair was waiting. He protested: he hated being carried around in those things, he'd far rather walk. They ignored him as though he hadn't spoken, which put him in his place. He particularly hated it when one of the four chairmen was a few inches taller than the others. It meant that one corner of the chair was always higher, while the man diagonally opposite was taking more than his fair share of the weight, which meant he stumbled on cobbles.
