The collapse was neither loud nor total. It was a wet, sucking thud.
Captain Kroll’s black warhorse drove its forelegs into what looked like a firm earthen ramp, expecting packed clay. Instead, sixteen hundred pounds of armored destrier and rider plunged straight into an underground pocket of liquid lime slurry and loose river silt.
The crust gave way with the sound of a boot pulling out of a bog.
The stallion sank to its chest in half a heartbeat. It let out a scared, bubbling whinny, thrashing its heavy hindquarters. But the motion only melted the soaked silt further. Within seconds, the horse was wedged up to its saddle girth in warm, frothing white mud.
“Ambush,” a sergeant shouted from the second rank. “The ground is hollow.”
Two more cavalrymen, unable to check their forward driving force in the narrow hall, plowed directly into the collapsing berm.
Their mounts plunged sideways into the backup drainage drain pits. Horses shrieked, flailing in the thick, milky burning lime powder wash. Meanwhile, their riders were thrown over the pommels, crashing into the gravel in an ear-splitting clatter of blackened plate and chainmail.
Behind them, the rear ranks panicked.
Horses reared, iron shoes slipping on the icy approach road. Crossbowmen cursed as their mounts collided in the narrow twelve-pace gap between the wetland and the ditch.
“Form line,” Skag screamed from the rear, waving his sword wildly. “Archers, shoot the low roof wall. Shoot them down.”
On the narrow high walkway, Kenneth Drake raised his hand. Twelve guard post archers stepped to the arrow slits, heavy hunting bows drawn to the cheek, feathers touching their ears.
“Target the horses, Kenneth?” Kenneth muttered, his knuckles trembling on the release. “One volley into that tangle and none of them ride home.”
“Hold your fire, Kenneth,” Giles commanded sharply.
Kenneth lowered his bow half an inch, staring at Giles. “Lord Giles. They came to burn our home.”
“They came to fulfill an ill-advised subcontractor agreement,” Giles said. “We don’t execute human labor assets when a non-lethal settlement is exactly superior. Look at them. They’re locked still.”
Giles stepped onto the forward timber projection above the gate. He looked down into the churning mud pit.
Captain Kroll had scrambled free of his saddle, but he was stuck waist-deep in the thick lime slurry. The skin-burning wash had soaked through his boiled-leather faulds. Every time he tried to heave a leg out, the suction pulled him down another three inches.
Six other hired blades lay groaning on the gravel bank, winded from their falls. Behind them, fourteen horses were hopelessly bogged, their eyes rolling white with terror.
Giles cleared his throat.
“Captain Kroll,” Giles said, his voice level and clear. “You’re experiencing nearby soil liquefaction induced by a loose high-pressure backfill trench. The slurry consists of calcium hydroxide, soaked river silt, and water. It’s non-toxic, but highly bitter-salt. If you remain in that pit for twenty minutes, the lye will cause chemical dermatitis and your boots will dissolve.”
Kroll wiped white slurry from his eyes, spitting grit. He looked up at Giles, then at the twelve heavy arrow points aimed directly at his throat from twenty yards away.
“You trapped us,” Kroll wheezed, his teeth gritted against the burning lye. “A witch-hole in the road.”
“It’s a loose wastewater overflow sump,” Giles corrected. “I warned you about the earth-measuring boundary. Now, here is your town ultimatum.”
Giles pointed with his boxwood folding rule.
“Drop your broadswords. Unstring your heavy steel crossbows. Instruct your rear ranks to dismount and ground their arms. If you comply, my crews will bring block-and-tackle rigging, pull your horses from the mud, and wash them with fresh river water before the lime burns their hocks. Plus, your men will receive hot parsnip porridge and dry wool blankets in our sick room.”
Kroll stared at him through mud-crusted eyelashes. “And if we refuse?”
“If you refuse, we leave you in the sump,” Giles said calmly. “The surrounding heat is twenty-four degrees and falling. In two hours, the mud freezes solid. You’ll become a permanent crushing foundation element for our southern roadway.”
Kroll swallowed hard. He looked at his thrashing stallion, whose nostrils were flared in desperate tiredness. Then he looked back at the cold, steady eyes of the land-mapper on the wall.
“We surrender,” Kroll yelled, throwing his mud-soaked broadsword onto the gravel. “Guard post, ground arms. Ground your steel.”
A clatter of iron swords and heavy steel crossbows echoed along the approach road as the shaken hired blades dropped their weapons into the snow.
From the rear of the column, a shrill shriek of backstabbing broke the silence.
“Cowards,” Court guard Skag roared, his face white with terror. “Traitors. I’ll have you all hanged at Fort Harrowgate.”
Skag wheeled his gray gelding, slammed his spurs into its flanks, and bolted south. But the gelding had taken only five strides before its hooves struck the slick, frozen clay of the bypass swale. The horse lost its footing, crashed onto its side, and threw Skag into a thick bramble patch.
Skag scrambled to his feet, bleeding from scratches across his nose. He looked back at the thirty armed convicts watching him from the ditch. Then he sprinted on foot into the rising blizzard. He wept in terror.
“Shall I send an arrow after him, my lord?” Kenneth asked, sighting along his shaft.
“Let him walk,” Giles said, pocketing his rule. “Fort Harrowgate is forty miles south through an active wolf hall. His survival probability without a mount is under eighteen percent. Bram, get the recovery tackles. We have fourteen horses to rescue.”
* * *
The recovery operation took three hours of grueling, careful labor.
Master Borin brought two heavy ash sheer-legs and a double-purchase block-and-tackle from the storehouse. Working under Giles’s direction, the exiles rigged wide canvas slings beneath the bellies of the trapped warhorses.
Caleb Thorne-Wood anchored the guy-ropes to stout pine stakes driven into the frozen roadway. Six men on each haul-line heaved in steady all at once, chanting an old sapper rhythm as the wooden pulleys creaked under the huge strain.
One by one, the massive chargers were hoisted from the sucking lime slurry and deposited safely onto the dry gravel road.
Sister Teresa stood by the wash-trough with buckets of warm river water and dilute cider vinegar, scrubbing the white skin-burning mud from the horses’ legs and nostrils before the lime could blister their skin.
“Be still, noble creature,” Teresa crooned, washing the trembling flank of Kroll’s black stallion. “The white fire has passed. You’re delivered from the hands of the oppressor.”
The stallion nuzzled her shoulder, blowing warm steam against her habit.
Down at the sick room tent, Teresa inspected the dismounted hired blades. Aside from two out-of-joint shoulders, a sprained ankle, and severe skin irritation from the lime slurry, there were no mortal injuries. She washed their legs in vinegar basins and bandaged their scrapes with clean linen.
“A miracle,” an older mercenary whispered, touching his bandaged wrist. “We charged an unmortared ditch and not a man among us tasted iron.”
“It wasn’t a miracle,” Teresa informed him sternly. “It was the mercy of the Lord Master builder. Drink your bone broth and repent of your trespassing.”
Kenneth Drake walked down the stable line behind the granary. There, Dob was rubbing down the eight heavy warhorses with bundles of dry rye straw.
“Look at the bone on these beasts,” Kenneth murmured. He ran his palm down the shoulder of a bay mare. “Fourteen hands high, broad chests, iron hocks. At Dun-Krag, an officer would pay sixty silver crowns for a mount like this. Skag bought them with royal credit, and now they belong to our logistics pool.”
“They don’t belong to the guard post, Kenneth,” Giles corrected. He walked up with his wooden ruler. “They belong to the town transport division. A heavy warhorse has a tractive drawbar pull of twelve hundred pounds. Hitching four of these animals to timber sledges will increase our corduroy road construction speed by three hundred percent.”
Kroll stood by the stable door, a wool blanket over his shoulders, watching Dob work.
“My boys raised those mounts from colts,” Kroll said quietly. “If you work them on road timber, don’t gall their shoulders with green leather.”
“We use padded sheepskin collars and balance the hitch angle at fifteen degrees to minimize spine strain,” Giles replied. “In this settlement, draft animals receive the same heat and ergonomic upkeep as human labor. Tomorrow, your wagon drivers will drive them.”
Kroll looked at Giles for a long moment, then nodded once, his hard face softening. “You run a strange camp, Lord Giles. But you keep your word.”
* * *
Meanwhile, Kenneth Drake and Toby Karr conducted an inventory of the captured weaponry in the yard.
“Twenty heavy steel crossbows,” Kenneth reported, laying them across a split-log bench. “Twelve hundred quarrels with chisel-headed armor-piercing points. Eight heavy warhorses in sound health, six lighter cavalry geldings, and forty blackened broadswords. Lord Giles, this gear doubles our guard post’s defensive firepower.”
“It provides valuable defensive materiel,” Giles agreed, inspecting a captured heavy steel crossbow prod. “The spring steel in these bows is high-grade. If we ever face armored frost units, these prods can be adapted into static twisting force giant crossbows. For now, oil the gears and store them in the armory.”
Lady Millicent Croft sat behind her frame stand table in the third bunkhouse, her ledger open and her traveling sandbox ready.
She distributed wooden bowls of hot smoked-trout chowder and dry wool wraps to the twenty captives seated along the benches.
“Name, rank, and main civil trade,” Millicent demanded, dipping her steel pen.
Captain Kroll sat on a bench, wrapping his hands around the steaming bowl. He took one sip of the rich, savory broth, and his scarred shoulders visibly slumped in relief.
“Kroll,” he muttered. “Formerly master sergeant, Third Sapper Cohort of the Royal Marches. Most of my boys were road-builders and ditch-diggers before the border wars.”
Giles stepped into the bunkhouse, wiping mud from his cuffs.
“Road-builders?” Giles asked, his eyes lighting up with the intense satisfaction of a builder discovering an unexpected pool of skilled subcontractors. “Captain Kroll, your bail is officially set.”
Kroll looked up, wary. “Bail? In silver?”
“In linear yards,” Giles said. “You and your men owe this municipality two miles of crowned corduroy roadway across the southern flats. Tomorrow morning at seven, you pick up your tools.”
Kroll looked at his men, who were already scraping the bottoms of their bowls and stretching their legs near the warm stone hearth.
“Two miles of road,” Kroll said slowly. “In exchange for full bellies and no irons?”
“Ten-hour shifts,” Giles said. “Twenty-four hundred calories daily. Hot tea at ten and two. If your work meets town grade, House Croft will pay standard guild wages upon completion of the contract.”
Kroll set his bowl down and rubbed his scarred face with both hands.
“Lord Giles,” the mercenary captain muttered, “Court guard Skag told us you were an outlaw. But I’ve served three dukes and a royal legate, and not one of them ever fed a prisoner a hot meal before asking for his parole.”
“Feeding prisoners is standard labor upkeep,” Giles said. “Starved pawns exhibit a sixty percent reduction in shovel throughput. Rest well, Captain. We have two thousand yards of timber to fell before noon.”
