Lieutenant Chask had laid the chalk line for the first charge when something with six legs refused to kneel.
It stood in the sanctuary yard beyond the split gate, a broad-backed animal under a carrying frame, while three goblins hauled at the breast strap. A woman on the wall raised one arm. Her warning crossed the ravine as three sounds at once: a raw scrape, a vibration that reached Chask’s palms through the stone, and hard little clicks that might have been pebbles striking a bowl.
The goblins stopped hauling. The animal did not move. One of them unbuckled two grain panniers and shouldered a sack himself. Only then did the beast step into the lane climbing toward the inner ruin.
“Signal discipline,” the captain said behind Chask. “Better than some companies.”
Chask sighted along her chalk. The broken causeway rose in two turns from the ravine, narrowing at the last switchback before it met the sanctuary wall. The host filled the lower turns: shields, pikes, hooded lamps, men breathing steam into the predawn dark. On the upper shelf, her six sappers had room to work only because the point company held back.
Across the wall, figures passed buckets in one direction and bundles in the other. Goblin auxiliaries, Chask classified. War-beasts under burden. Three pale shapes crawled low along a colonnade where no soldier would have chosen to put a knee. The woman on the wall was Halwen, called Mother of Monsters in every order Chask had received. The orders wanted her taken, or failing that, killed.
The captain touched the horn at his belt. “Third signal, breach. Chainhouse open by dawn.”
“The face is shedding,” Chask said. Stone grit ticked down the wall below her mark. “Give me another quarter-hour and I can seat the charge deeper.”
“Third signal, breach. Chainhouse by dawn.”
There was his answer. Chask drove the last waxed wedge around the powder crock and sent her team back along the upper shelf. The sanctuary traffic had quickened. Halwen sounded again. Rasp, buried thunder, teeth-hard clicks. Some in the yard looked up. Others kept carrying. The pale crawlers vanished under an arch. The six-legged beast turned sideways to let a handcart pass, though Halwen had not moved her arm.
The horn gave its third note.
Chask touched the fuse.
Flame ran under the clay cover. She counted to eight before the wall struck her flat.
The blast broke inward as intended, but the old masonry did not stop breaking. A seam unstitched itself down the face and crossed beneath the gate. The upper shelf kicked. Through the opening, Chask saw a paved yard buckle and a stone mouth sink by half its height. Then an ember-bright timber dropped from the breached wall into stacked brushwood. Fire climbed it at once.
Men shouted behind her. Someone dragged her by the back of her harness as blocks rained onto the causeway. She found her feet, found all six sappers moving, and found the captain already pointing through the dust.
“Inside. Chainhouse.”
“We struck a void under the gate.”
“Inside, Lieutenant. The breach is made.”
The point company went through before the smoke cleared. Chask followed because the upper approach had begun to list toward the ravine, because her people were looking at her, and because the second powder crock was already on two sappers’ shoulders.
Inside, nothing kept its proper military shape.
A goblin in a leather apron stood on a broken fountain and called numbers in rough trade speech. “Six hands to grain. No—two. Six to water. Bandage chest goes broad road.” He pointed at bearers rather than bodies, and the bearers contradicted him by pointing at their own loads. Beside the undercroft mouth, a horned woman tightened a splint on a wounded figure whose face Chask could not see. Two small goblins carried the figure’s shield away, then returned with a door to use as a litter. At the breach, four long-limbed beasts pushed into the smoke and set themselves in a bristling line against the burning brush, their backs to the soldiers still coming through, stamping out brands before they could roll into the lane. None of them looked toward Halwen.
The captain saw the line. “Skirmish screen.”
“They’re facing the fire,” Chask said.
“Chainhouse.” He pointed across the yard to a squat tower joined to the inner gate by black lengths of chain. “Second charge. Ten minutes.”
A clicking came from under Chask’s boots.
She threw herself aside. A flagstone dropped where she had stood, exposing a drop into dark air and the snapped curve of a brick vault. One of the pale crawlers clung head-down to the colonnade. Lamplight traveled over pearled skin as the figure uncovered and covered a shuttered lantern: twice, pause, once. A free hand tapped the pillar.
The goblin on the fountain shouted, “Nacre says bad roof. Or bad floor. This stone. Not all stone.”
Nacre flashed twice again and jabbed toward the chainhouse.
“Which stone?” Chask called.
Nacre tapped three quick strokes, waited, then tapped them farther along the pillar. The rhythm moved toward the tower.
The captain stepped over the hole. “Ten minutes.”
Chask sent two sappers to probe ahead with their setting rods. She took the crock around the broken pavement herself. The crack beneath the yard traced the line of the half-collapsed undercroft, the void their first charge had found and punished. Smoke pressed down from the burning wall. People vanished into it carrying water, returned empty, and chose new work when the bucket line failed.
At the chainhouse door, Halwen barred their way.
She was taller than Chask had judged from the wall and older than the army broadsheets made her, with cropped gray hair and a soot-black coat laced tight at one wrist. Nothing crowned her. A ring of keys hung at her hip beside a mason’s plumb bob. When she spoke, the first word tore into a rasp, a low tremor rolled beneath it, and clicks crowded its end.
“No powder here.” The words were human words, but strained through the three noises until Chask had to fit them together from pieces.
Around them, several refugees moved at the rasp. A few ducked. One covered a lamp. Most did neither. The long-limbed rearguard at the fire shifted when the low vibration reached them, then settled again by watching one another.
“Stand aside,” the captain said. “The gate mechanism is military property under seizure.”
Halwen’s next breath clicked hard enough to fleck blood onto her lip. “Your blast broke the broad road.”
Behind her, the chainhouse floor was crowded with winding drums, brake levers, and stone counterweights. The inner gate’s chains wound onto the main drum; the largest chain ran apart from them, down through a slot toward the undercroft mouth. Families were moving through the room, some toward a narrow stair, others down a ramp wide enough for the six-legged beast. Not troops awaiting orders. Traffic under pressure.
Chask set down her end of the crock. “Where does the broad road pass under this floor?”
Halwen looked at the setting rods and then at the captain’s sword. “Away from you.”
“If the crack has crossed its roof—”
“Away.” She kept one hand on the doorframe, and the hand was shaking.
The apron-wearing goblin shoved between two sappers with a crate against his chest, making for the ramp.
“Kritt.” Halwen’s voice split his name into scrape, pulse, and one hard click. She caught the frame when her balance went.
“Salt, lamp oil, medicine,” Kritt told her. “Grain stays.”
“North bins first. Winter—”
“North burns in four minutes. Winter weighs nine hundred.” He dropped the crate beside the ramp. “No.”
He turned his back on her and pointed two goblins toward the medicine chest. One went. The other shook her head, lifted a small child from beneath the winding drum, and took the stair instead. Kritt swore, revised his count on his fingers, and waved a pair of larger bearers into the empty place.
The captain drew a red cord from the powder crock and put it in the nearest sapper’s hand. “Place it on the main drum.” His eyes went to Halwen, to the blood on her lip and the hand on the frame. “When the charge is seated, Lieutenant, you will secure the woman.”
Chask crouched at the floor crack without answering. Air moved through it, pulling smoke downward. She put two fingers to the stone and felt a steady tremor: feet, many of them, passing below. The broad road ran directly under the chainhouse.
“Not the drum,” Chask said. “We need the foundation.”
Halwen’s gaze sharpened. The captain only nodded. A foundation charge was ordinary practice against a gate tower.
“Show me the ramp line,” Chask said to Halwen.
“You’d follow—” The clicks buried the rest. Halwen wiped her lip with the back of her wrist and did not try again.
“This crack is over your road,” Chask said. “I can feel your people walking under it. I need to know how far it runs.”
The captain cut in. “Eight minutes.” He went out into the smoke, calling for the point company.
Halwen pushed away from the frame and turned to the room. Her voice went out over the drums and the crowded ramp in its three torn pieces. “Big ones. Ramp.” A click caught in her throat; she spat red. “Small. With Nacre. West passage—” She shook her head. “Shut. Kitchen door. Mine.”
A horned bearer swung a handcart toward the ramp. Two goblins looked up at the stair and stayed where they were. Most of the room went on carrying as if nothing had sounded.
“How many on the ramp?” Chask asked.
Halwen did not look at her. Kritt rounded on Halwen from the medicine chest, counting at her on his fingers. “Broad road, forty-two walking, seven carried, three frames. Crawlway had thirty. Then Nacre changed the line. Now more small to Nacre?” He opened his hand at her, empty. “Count went bad.”
As if to demonstrate, the six-legged beast entered the chainhouse with only one pannier left. A goblin tried to strap the medicine crate onto the vacant side. The beast folded all six legs and flattened its ears. When the goblin tugged, it rolled enough to pin the loose harness under its weight.
Kritt slapped both palms against his thighs. “It says one side pulls wrong.”
“It says no,” Halwen said.
Kritt stared at the blocked ramp, then kicked the harness buckle free. “No load.” He split the medicine into two canvas bags and handed them to separate bearers.
Nacre dropped from the colonnade into the doorway, landing in a low fold of limbs. Up close, Chask could see old mortar whitening their fingertips. Nacre tapped the floor, three strokes and then two, flashed the lantern at the ceiling, and pointed down the ramp.
“Three roof ribs, two broken?” Chask guessed.
Nacre went still, then struck three stones in sequence. The first rang. The next two answered dull.
There it was. The chainhouse load traveled across three ribs; two had detached from the wall. Powder set anywhere in this room would punch the remaining rib into the ramp and drop the tower after it. Forty-two walking, seven carried, three frames—bad count, still enough to bury.
Chask crossed to the west wall. The crack rose through it, passed behind the counterweight guide, and continued toward the causeway abutment. The first blast had made the whole gate complex one failing structure. Put the powder here and the release would run both ways: down through the undercroft roof and outward into the upper approach, where the point company waited.
The crack, the failed ribs, and the loaded approach were enough for any board of engineers.
The captain’s horn sounded one short note from the yard.
“Six minutes,” said one of her sappers.
“Lift the crock,” Chask ordered. “We set at the outer switchback, on the open face.”
The sapper with the red cord did not move. “Captain said the chainhouse.” Beside him, another sapper looked at the doorway the captain had gone out by.
“Then I’ll answer for it. Lift.”
Halwen caught Chask’s sleeve. Her grip was hard, her footing suddenly not. “The switchback falls across the ravine traverse.” Rasp. Vibration. Clicks. Several heads turned at the vibration; two refugees started down the ramp, while Kritt kept loading medicine. He relayed the warning with two raised fingers. Farther down the ramp, someone answered with three knocks on wood; from the yard came a shrill animal call that Halwen did not echo.
“Then clear the traverse before the fuse reaches the bend.”
“You will close our return.”
“Yes.”
Halwen’s eyes followed the largest chain down through its floor slot. Then she released Chask.
A falling lintel struck the doorway before they could move the powder. One end smashed into the floor. The other lodged against the frame, leaving a triangular gap too narrow for the crock.
Smoke swallowed the yard beyond. A soldier screamed once, then coughed. The captain’s horn repeated the short note.
Two sappers levered at the lintel. Another knelt by the crock, pulled the fuse out of its clay collar, and cut it short with his knife. A long burn on the open bend would give anyone time to stamp it out.
“I’ll take the fuse through the gap and have the groove cut before the powder gets there,” he said.
“You’ll need to pass the point company.”
“They know my coat.” He wrapped the cut fuse around his wrist, crawled under the lintel, and disappeared into smoke.
One of the lever team watched him go. “I’m not telling the captain the powder sat behind a rock.” She reset her bar deeper under the lintel. “I’ll shift it.”
The others braced with her. Chask joined them, and Kritt shouldered in at her elbow. From the yard side, hands of several shapes appeared under its edge. Kritt shouted, “On three.” A stone shifted at two; everyone heaved early. The lintel rose a hand’s breadth, and they jammed a bar under it to hold the gap.
Nacre flashed a rapid burst toward the ramp. Small figures peeled out of the ramp traffic and followed Nacre up the narrow stair: two goblins, a many-jointed refugee carrying a bundled infant, a wounded traveler walking with one arm over someone half their height. Others tested the stairwell and turned back when shoulder, horn, or carrying frame would not clear it.
At the winding drum, Halwen hauled the brake lever and failed to move it. She had meant to keep the counterweight; Chask saw that in the careful wedges, the oiled chain, and a winter stores schedule chalked beside the drum. Without its pull, the damaged undercroft gate would open only halfway.
Kritt dragged the last medicine bag to the ramp. Behind him the north roof burned through, dropping sparks into the grain bins.
“Oil?” he called.
“Leave it,” Halwen tried to say. The word was only voiceless air. No rasp, vibration, or clicks followed. She lurched against the brake stand and pressed both hands to her throat.
Kritt looked at the bins, at the ramp, and at her. “Grain stayed,” he said. “Oil too.”
He went down the ramp.
Halwen took a hammer from the wall. Chask knew what she meant to do a moment before the blow landed. The holding pin snapped. The counterweight dropped through its shaft with a roar, flinging the chain off the drum. Below, the undercroft gate crashed open; the shock tore the brake stand from its bolts and ruined every careful sequence the chainhouse had once controlled.
Halwen fell to one knee. No warning followed. Silence, and the curse with it.
The six-legged beast rose at the sound of the opening gate and went down the ramp. It carried one pannier, no driver. The rearguard came backward from the fire in pairs, one dragging an injured companion, another staying until the last stragglers were past. At the undercroft mouth, the horned healer shoved the door-litter ahead and turned back for someone Chask could not see.
Chask’s sappers shouldered the powder and turned for the lifted gap. Halwen pushed herself up and pointed the other way, at the old kitchen door in the back wall. Beyond it a ledge ran along the ravine. The route she had kept for herself.
“That comes out at the switchback?” Chask asked.
Halwen nodded once.
They carried the crock out by the kitchen door.
The ledge met the upper switchback behind the waiting point company. Below, refugees spilled from the wrenched-open undercroft gate and divided. Nacre’s smaller group emerged farther down through a crack in the ravine wall, their shuttered light blinking over bad footholds. Broad-bodied beasts took the exposed traverse in single file. The wounded went between them where the path widened. Kritt had stopped at the far turn to throw medicine bags across a washout one at a time; when someone reached back for him, he bared his teeth and threw the second bag instead.
Chask sent two sappers to move the point company up the shelf toward the breach, out of the fall line. She set the charge against the unsupported face of the switchback. Here the blast could spend itself into open air. Here the falling shelf would tear away the host’s only road up and cover the traverse after the last refugee crossed it.
The captain came through the smoke with four soldiers. “The chainhouse, Lieutenant.”
Chask packed clay around the crock and did not look up.
“The chainhouse was the objective.”
Her hands kept working. The captain’s eyes went to the people below. “You are cutting pursuit.”
“I am cutting a failed load path before the host puts another five hundred men on it.”
He reached for the fuse. Halwen stepped between them with the hammer hanging from one hand. No one gathered at her back. Nacre was gone. Kritt was below. The rearguard had made its own retreat.
The captain drew his sword.
Chask looked down the traverse. The six-legged beast had stopped at the washout. No handler pulled it. It tested the edge with one forefoot, withdrew, then climbed upslope on a narrower line no cart could use. Of the beasts behind, two followed, one waited for the door-litter to pass, and another turned down toward the water.
The last rearguard pair cleared the fall line.
“Fuse,” Chask said.
Her sapper struck the match.
The captain put the sword point against Chask’s breastplate, but the fuse was already spitting into its clay groove. His four soldiers looked from it to the tilting stone under their boots. One retreated toward the sanctuary. Two followed. The fourth seized the captain’s arm without asking leave and pulled.
They ran.
Chask caught Halwen when the ledge pitched beneath them. Halwen struck her hand away, found the wall, and ran on her own. Behind them, the switchback lifted with a flat orange flash. The outer curve broke into three vast slabs and went down. Dust filled the ravine. Stone hammered stone, then dwindled to a patter.
When the air cleared enough to breathe, the road from the host ended in empty space.
Below, no single column moved away. Nacre’s lights descended along the narrow cleft until rock hid them. Kritt and the litter bearers took the watercourse. The six-legged beast and two others climbed the bare slope. Halwen stood on the ruined wall above them, swaying, one hand clamped to her throat, and watched each route until it emptied.
The host sounded advance from the lower switchback. The note met the break and became confused shouting. Ropes would come. Timber would come. Rebuilding the approach would take hours.
The captain found Chask beside the breach. Dust had grayed his face. “You will account for that charge.”
Her sappers came in by twos from their positions. The man who had carried the cut fuse returned without it, his coat torn at one elbow. Among the six were burns, torn sleeves, and a shoulder held stiff. All were walking.
“The chainhouse foundation had lost two of three supporting ribs,” Chask said. “Detonation there would have collapsed the undercroft vault and displaced the approach abutment under our own troops. I relocated to the nearest unsupported face with an open vent.”
Below them, the host tried another horn sequence. Halwen climbed down the outer face of the wall without looking at Chask. The captain watched her until she reached the ravine floor. His four soldiers watched him. He gave no order. Kritt had come back up the watercourse with the litter, and he waited only long enough to hand her one end. She wrenched it from him and set off at a pace that made him trot to keep his end level. Together they followed the watercourse out of sight.
“You will repeat that exactly,” the captain said.
“Yes, sir,” Chask said.
She checked the crack running from the chainhouse to the new edge of the road. It was still widening. She raised her setting rod and sent the point company back into the yard.
