Orders from the Capital

Why had the southern toll-clerks permitted a twelve-ton iron engine onto a bridge they had spent sixty years claiming was unsafe? Knight-Constable Ifeanyichukwu-eke stood by the iron-banded left wheel of the grand timber siege-engine, his hand resting on the pommel of his broadsword while sulfurous steam hissed through the decking seams beneath his boots. Chief Clerk Nwoye had haggled at dawn over axle-timber fees and groats for the draft beasts, forcing Ifeanyichukwu-eke to fling down a silver torque just to clear three light carts and thirty foot soldiers. Yet before the northern portcullis dropped, a captain in the rear-guard, defying Ifeanyichukwu-eke's strict order to leave the heavy timber wains along the cliff wall, had driven this monstrous war-wagon onto the span behind them without paying a brass bit. Now, his three supply carts and this rogue machine sat stranded between two barred gates, and the ground was turning warm.

The wheel stood hub-deep over the fourth vertebra. Where petrified bone should have formed a continuous, fossilized arch, a fissure four inches wide split the white road deck from rail to rail.

"Who gave the order to drive these?" Ifeanyichukwu-eke asked.

Master Drayman Madu wiped grease across his forehead with a dirty sleeve. He pointed a scarred thumb toward the axle. "The beasts were balking, Captain. The left rear hub caught the ledge when the bridge dipped. We had twelve draft beasts straining in the traces and two carts behind us pressing the tongue. If we halted on the seam, the tongue would have snapped."

"So you drove thirty-six wedges of green spruce into the spinal seam of the Great Span."

"Soft spruce gives, Captain," Madu muttered, squinting down into the boiling fog below the deck. "Oak would have split the bone."

"Soft spruce rots in tallow," Ifeanyichukwu-eke said. He nudged the nearest wedge with the brass toe of his boot. The white resin in the timber was already blistering, turning brown where thin, yellow marrow-sweat wept out of the fracture. A reek like boiled horn and stagnant river mud rose between the planks. "Spruce holds nothing. It compresses under ten hundredweight. You have wedged twelve tons of southern timber and cast iron over an open vent."

Further north, past the fifth rib, the mortar-mason Ebele-oma was shouting at two teamsters who had failed to secure their oxen to the center guide-rail. Her voice carried thin and sharp against the rising dusk wind, swallowed periodically by the canyon's hollow whistle. She had warned him at midday that the span was rejecting metal, showing him her marrow-pitted blade after his own spearman fell into the mist. Now, looking down at his stirrup leather, Ifeanyichukwu-eke saw the iron buckles flecked with the same caustic grey powder.

Hoofbeats rattled across the bone deck from the south.

A solitary rider on a sweat-lathered roan navigated the narrow aisle between the baggage carts. The courier wore the red woolen surcoat of the Southern Duchy's courier service, but his leather boots were splashed with grey mud from the low road, and his mount had blood running from its bit.

The horse skidded to a halt ten paces from the stalled engine. Its nostrils flared wide, catching the stench of the boiling marrow, and it backed toward the outer timber railing until the rider sawed the reins savagely to the left.

"Knight-Constable?" the courier gasped. He swung down from the stirrup, stumbling as his heels struck the calcified decking. "Urgent dispatch from the southern command tent. By hand of Chief Clerk Nwoye's forward runners."

"The northern portcullis is dropped," Ifeanyichukwu-eke said, not moving from the wheel. "The crossing is closed. Why has your master sent a horse onto a quarantine deck?"

The courier unbuckled a brass cylinder from his hip and held it out with a shaking hand. "Orders, Captain. From Arch-Marshal Okoye's headquarters at the southern approach. The marshal demands to know why the vanguard halted before the northern abutment."

Ifeanyichukwu-eke took the cylinder. The wax seal bore the charging bull of the Southern Duchy, stamped cleanly in red beeswax. But as he turned the brass tube in his palm, his thumb caught the hem of the courier's saddlecloth. Beneath the quilted wool, tied to the cinch with greasy cord, hung a second cylinder. It was made of lead, dipped in black pitch, and bore no heraldic stamp.

"What is that?" Ifeanyichukwu-eke asked.

The courier reached for the lead tube, his fingers jerking back as Ifeanyichukwu-eke stepped between him and the horse. "Personal effects, sir. My private manifest."

"Clerks carry manifests in cedar boxes," Ifeanyichukwu-eke said. "Only division marshals carry pitch-dipped lead. It keeps out wet marrow and burning brine."

He caught the courier by the collar of his surcoat and dragged him against the wagon's iron rim. The man was light, barely twenty winters old, his collarbone sharp through the linen tunic. With his left hand, Ifeanyichukwu-eke drew his skinning knife and severed the cord binding the lead cylinder to the saddle cinch.

"That carries the Arch-Marshal's private mark," the courier whispered, his eyes darting toward the southern approach where the fog was turning violet in the evening chill. "If you break the pitch, it is mutiny under the March Law. You must sign the voucher first. Three copper farthings for the crossing fee, plus the hazard stamp. Chief Clerk Nwoye made me swear on the ledger."

Ifeanyichukwu-eke let the boy go. He looked down at the boy's bridle. The brass rosettes on the cheek-straps were turning green where marrow vapors drifted from the crack, the metal sloughing away in fine flakes.

"Tell Nwoye to bill the canyon," Ifeanyichukwu-eke said.

He slit the black pitch with the tip of his knife and twisted the lead cap. Inside lay a single roll of goat-skin vellum, stiff with mutton grease to repel moisture.

Ifeanyichukwu-eke unrolled the sheet against the timber wagon bed.

The parchment was penned in the cramped, angular hand of the southern chancellery and counter-signed with Arch-Marshal Okoye's private signet in black wax. It had not been drafted this morning. The date on the margins was seven days old, stamped before the vanguard had ever departed the capital muster-grounds.

To the Forward Battery Commanders:

The northern ribcage exhibits extensive sub-surface necrosis. Advise all heavy artillery and timber towers to proceed at maximum draft across ribs four through nine. Should the bridge deck fail under transit, northern access will be permanently denied to the Northern League. If the dormant entity reacts to the localized weight, observe the emergence pattern from the southern redoubt. Under no circumstance may the baggage train reverse direction or relieve the load upon the vertebrae.

The grease on the vellum chilled his fingertips.

They had never been an invasion force. They were forty tons of lead, timber, and iron swung like a hammer against an ancient eggshell, sent to see whether the shell cracked or hatched. The southern court had not gambled on their victory; the ministers had calculated the price of a trapped vanguard and thirty soldiers against the destruction of the northern trade route.

For twelve years he had served the Duke of Ozu-South, believing every road built of bone was an altar to order. The discipline he took pride in was nothing more than an executioner's blindfold.

Ifeanyichukwu-eke rolled the vellum tight and shoved it inside his leather brigandine.

"Madu," he said.

The master drayman was leaning over the spruce wedges, watching white froth bubble from the seam. "Captain?"

"Cut the traces."

Madu blinked, his mouth dropping open. "Cut them? We have twelve draft beasts hitched to the tongue. This engine cost three hundred silver talents to cast in the capital foundry. If we drop the tongue, the wagon cannot be moved without a derrick."

"I did not tell you to move it," Ifeanyichukwu-eke said. His voice was level, stripped of the military bark he had used since dawn. "Cut the harness collars. Lead the horses south toward the gatehouse. Form the infantry into ranks of two along the dorsal ridge where the bone is six feet thick. Leave the war-wagon."

Two men-at-arms in heavy brigandines stepped forward from the escort. "Captain, the Arch-Marshal's guards at the south approach have the gate locked. They will not admit unlimbered teams without an order from the chancellery."

"Then they can explain to twelve draft horses why the road is closed," Ifeanyichukwu-eke said. He took an axe from the wagon rack and swung it down onto the heavy hemp trace of the lead horse. The oiled rope parted with a dry slap.

The great dray horse lurched forward, startled by the sudden release of tension. Madu grabbed its halter, cursing under his breath as three teamsters scrambled with their knives, slashing through the trace chains and leather straps that bound the team to the iron tongue. One by one, the heavy horses were backed out of the yoke and led south into the dusk.

Then the weight began to shift.

Without the twelve horses leaning into the collar to brace the tongue, the full twelve-ton mass of the siege engine settled backward onto its rear iron axle. The iron tires bit into the calcified surface directly above the four-inch fissure.

A sound like green ice snapping under a sled runner echoed up through the timbers.

The thirty-six spruce wedges did not slip; they crushed. The soft green wood flattened into fibrous pulp under the sheer, unmoving iron tonnage. A cloud of fine bone dust and yellowish marrow steam burst from the fissure, spraying the hem of Ifeanyichukwu-eke's cloak. Beneath the iron tires, the petrified bone began to grind, sinking half an inch into the yawning hollow below.
