Chapter 24
WHERE DAHALT BORDERED ON NORTH ULFLAN'D a scarp eighty miles long, the front face of the Teach tac Teach, overlooked the Plain of Shadows. At a place named Poelitetz, the river Tamsour, flowing down from the snows of Mount Agon, cut a chasm which allowed relatively easy access from Dahaut to the moors of North Ulfland. Poelitetz had been fortified as long as men had made war across the Elder Isles; whoever held Poelitetz controlled the peace of Far Dahaut. The Ska, upon seizing Poelitetz, began an enormous work, to guard the fortress from the west as well as the east, so that it might be totally impregnable. They had closed the defile with masonry walls thirty feet thick, leaving a passage twelve feet wide and ten feet high, controlled by three iron gates, one behind the other. Fortress and scarp showed a single impervious face to the Plain of Shadows.
The better to reconnoiter the Plain of Shadows, the Ska had started to drive a tunnel out under the plain toward a hillock overgrown with scrub oak at a distance of a quarter-mile from the base of the scarp. The tunnel was a project executed with the utmost secrecy, concealed from all but a few Ska of high rank and those who dug the tunnel, Skalings of Category Six: Intractables.
Upon arrival at Poelitetz, Aillas, Yane and Cargus were subjected to a perfunctory inquisition. Then, instead of the maiming or mutilation which they had expected, they were taken to a special barracks, where a company of forty Skalings were held in isolation: the tunnel gang. They worked ten-and-a-half-hour shifts, with three half-hour rest periods. In the barracks they were guarded by an elite platoon of Ska soldiers and allowed contact with no other persons of Poelitetz. All realized that they worked as components of a death-squad. Upon completion of the tunnel they would be killed.
With death clear and large before them, none of the Skalings worked in haste: a situation which the Ska found easier to accept than to alter. So long as reasonable progress was made, the work was allowed to go its own pace. The routine each day was identical. Each Skaling had his assigned duty. The tunnel, fifteen feet below the surface of the plain, ran through shale and compressed silt. Four men dug at the front face with picks and mattocks. Three men scooped the detritus into baskets which were loaded upon barrows and wheeled back down the tunnel to the entrance. The barrows were dumped into hoppers which were hoisted aloft by a crane, swung over a wagon, emptied, and returned below. A bellows powered by oxen walking around a windlass blew air into a leather tube, which led to the tunnel face. As the tunnel advanced, cribbing was set into place so that the overhead and the sides were lined with tarred cedar timbers. Every two or three days Ska engineers extended a pair of cords by which the direction of the tunnel was guided and with a waterlevel* measured horizontal deflection.
*The water-level comes in several forms. The Ska used a pair of wooden troughs twenty feet long with a section four inches square. Water in the troughs lay perfectly horizontal; floats at each end allowed the troughs themselves to be adjusted to the horizontal. By shifting the troughs in succession, the desired horizontal could be extended indefinitely, with an accuracy limited only by the patience of the engineer.
A Ska overseer directed the Skalings with a pair of soldiers to enforce discipline, should such control be needed. The overseer and the guards tended to remain at the open end of the tunnel, where the air was cool and fresh. By noting the rate at which the wagons were filled, the overseer could estimate the vigor at which the Skalings performed their duties. If work went well, the Skalings ate well, and drank wine with their meals. If they slacked or loitered, their rations dwindled in proportion.
Two shifts worked the tunneclass="underline" noon to midnight and midnight to noon. Neither could be said to be preferable since the Skalings never saw the sun and knew that they were never to see it again. Aillas, Cargus and Yane were assigned to the noon-midnight shift. Immediately they began to consider escape. The prospects were even more discouraging than those at Castle Sank. Barred doors and suspicious guards confined them off-duty; they worked in a tube similarly sealed against exit.
After only two days of work, Aillas told Yane and Cargus: "We can escape. It is possible."
"You are more perceptive than I," said Yane.
"Or I," said Cargus.
"There is one single difficulty. We shall need the cooperation of the entire shift. The question becomes: are any so broken that they might betray us?"
"Where would be the motive? Everyone sees his own ghost dancing ahead of him."
"Some persons are traitors by nature; they take pleasure in treachery."
The three, squatting by the wall of the chamber in which they spent the off-hours, considered their fellows, one by one. Cargus said at last: "If we share together the prospect of escape, there will be no betrayal."
"We have to assume as much," said Yane. "We have no better choice."
Fourteen men worked the shift, with another six whose duties never took them into the tunnel. Fourteen men bound themselves in a desperate compact and at once the operation began.
The tunnel now reached about two hundred yards in an easterly direction under the plain. Another two hundred yards remained, through shale, with occasionally an inexplicable ball of iron-hard blue sandstone sometimes three feet in diameter. Except for the sandstone, the ground yielded to the pick; the face moved forward ten to fifteen feet a day. A pair of carpenters installed cribbing as the tunnel advanced. They left several posts loose, so that they might be pulled to the side. In the gap thus cleared certain members of the gang dug a side-tunnel, slanting toward the surface. The dirt was shoveled into baskets, loaded aboard barrows and transported back precisely like dirt taken from the face of the tunnel. By partially closing two men into the side-tunnel, and with the rest of the men working somewhat harder, there seemed no lessening of progress. Always someone with a loaded barrow waited thirty yards from the start of the tunnel, should the overseer decide to make an inspection, in which case, the lookout jumped on the ventilation tube to warn his fellows. If necessary he was prepared to turn over his barrow, ostensibly by accident, so as to delay the overseer. Then when the overseer passed, the barrow was rolled so as to flatten the ventilation tube. The far end became so stifling that the overseer spent as little time as possible in the tunnel.
The side-tunnel, dug five feet high and three feet wide, and slanting sharply upward, went swiftly, and the diggers probed continually with cautious strokes, lest, in their zeal, they strike a great hole into the surface which might be visible from the fortress. At last they found roots, of grasses and shrubs, then dark topsoil and they knew the surface was close above.
At sunset the tunnel-Skalings took their supper in a chamber at the head of the tunnel, then returned to work.
Ten minutes later Aillas went to summon Kildred the overseer, a tall Ska of middle-age, with a scarred face, a bald head and a manner remote even for a Ska. As usual Kildred sat gaming with the guards. He looked over his shoulder at the approach of Aillas. "What now?"
"The diggers have struck a dike of blue rock. They want rock-splitters and drills."
"'Rock-splitters'? What tools are these?"
"I don't know. I just carry messages."
Kildred muttered a curse and rose to his feet. "Come; let us look at this blue dike."
He stalked into the tunnel, followed by Aillas, through the murky orange flicker of oil lamps, to the tunnel face. When he bent to look for the blue dike, Cargus struck him with an iron bar, killing him at once.
