The Span Between Two Fires

Would two hundred armed men notice a traveling puppeteer crawling into their firing lane on his stomach? The question prickled my neck as I backed Kishi into the shadow of an undercut limestone bank, barely fifty yards north of the Ifeoma border bridge. Smoke from two converging vanguards was already tainting the river air with coal soot and dry sulfur. My only chance of keeping both armies from blowing the timber crossing into splinters was to inspect their lines before anyone pulled a lanyard.

"Stay down, old girl," I murmured, looping Kishi's lead rope around a sturdy willow root.

The mule gave a soft snort, dropping her nose into a patch of wild clover. Behind her, tucked into the dry creek bed beneath wild brambles, The Gilded Moth sat veiled under two coarse canvas tarps. With painted signboards wrapped in burlap and her brass smokestack folded flat against the roof, the wagon looked like an abandoned ditcher’s shed.

I reached under the wagon box. Pipu waited on his belly, his brass tail held at a stiff horizontal.

"Quiet paws today, little brother," I whispered.

I scooped him up, wrapping an oily rag around his rear paw-pads to deaden metal clicks against stone. The little terrier gave a faint hum from his spring casing, clockwork ears rotating toward the southern breeze. I slipped him into the deep pocket of my coat, checked my brass optical monocle, and dropped into the silt drainage ditch beside the towpath.

The ditch was cold and choked with yellowing bullrushes. Crawling through three inches of brown canal water ruined my second-best embroidered vest, but the mud banks kept me below sentry sightlines. Overhead, the rumble of iron rims against gravel and the clatter of marching boots grew louder.

Fifty yards down the winding cut, the ditch emptied into an arched masonry culvert draining the northern bridgehead. I slid inside, wading through ankle-deep silt until I reached the iron cross-grate beneath the eastern abutment.

The border bridge was a massive three-arch crossing. Heavy limestone piers anchored it into the gorge floor, supporting a broad deck of hewn cedar planks eighty feet above the water. In peacetime, grain wagons passed underneath in lazy procession. This morning, the gorge acted like an enormous stone speaking-tube, funneling every scrape of boots and shouted order down to where I crouched in the dark.

I pressed my back against the damp stone and peered through the grating.

Fifty paces to my left, on the eastern bluffs, stood Duke Oluwaseyi’s vanguard: eighty foot-soldiers in river-gray tunics kneeling behind wicker gabions, their long muskets leveled across the deck. Behind them, two polished brass six-pounders stood unlimbered on the roadway, crews standing rigid with ramrods raised.

At the head of the gray column paced Captain Danladi. His silver-plated gorget caught the morning light as he raised a battered tin megaphone.

"Hold the approach!" Danladi’s voice boomed across the river, rattling the cedar planks. "By decree of Duke Oluwaseyi, this crossing is under quarantine! Any armed carriage advancing within fifty paces of the middle pier will be treated as open insurrection!"

Across the timber span, on the western bluffs, a harsh clanking answered him.

Duke Chukwuebuka’s iron brigade had arrived. Sixty men in forge-blackened breastplates formed a wall of spiked shields. In the center sat a low, steam-driven road locomotive with iron skirts, its twin chimneys chuffing greasy smoke into the willow canopy.

An officer stepped forward carrying a square speaking-horn painted in red lead. That had to be Captain Boma.

"Save your breath for your rowboats, Danladi!" Boma barked across the water, his gravelly voice echoing off the cliffs. "Duke Chukwuebuka’s charter gives western ironmasters right-of-way over every timber span in this reach! Clear those brass toys from the eastern gate, or we drag them into the canal with our winches!"

"Advance one iron wheel onto that deck, Boma, and we sweep the planks with canister shot!" Danladi shouted back.

From up on the bluffs, the exchange sounded like the opening fanfare of war. But down in the culvert, the acoustic arch revealed an entirely different play.

The masonry channeled not only the shouted challenges, but the frantic muttering of the officers standing directly above the piers.

Danladi lowered his megaphone, shoulders sagging. "Sergeant," he rasped through the deck drainage vents. "Did the runner reach the garrison at Omu-Adu?"

"No sign of him, Captain," an older voice answered from the battery. "Roads north are empty. If Chukwuebuka’s steam wagon charges, our brass tubes will only bounce round-shot off their skirt-plates. We don't have enough iron bolts to crack that boiler."

"Then don't touch that lanyard unless they roll past the middle timber," Danladi muttered, wiping his brow. "The Duke swore in his dispatches that Chukwuebuka has an iron engine hidden in the trees that throws liquid fire. If we fire first and provoke it, we won't live to see noon."

On the opposite bank, through the gap between the bridge timbers, Captain Boma’s voice carried to his engineer.

"How much pressure in that tank, Garba?" Boma demanded.

"Barely forty pounds, Captain," the engineer hissed back. "The injector valve is leaking tallow. If I push the draft fan, the boiler flues choke before we reach the center planks. We can’t push a charge across."

"Keep the horn blowing," Boma whispered harshly. "Do not let them see the pressure needle drop. Duke Oluwaseyi has sixty rifled field guns marching down from the locks. If they realize we are running on spit and cold water, they will blow this bridge into kindling before our main regiment crosses the ridges."

I rested my chin against the cold iron grate, my chest tight. Neither captain wanted a battle. They were two terrified men holding empty hands, bluffing each other with noisy iron because their masters had filled their heads with nightmares of secret weapons. If either turned back, his duke would hang him for treason. If either stepped forward, the other would fire out of sheer panic.

In my pocket, Pipu shifted his weight. His balance wheel gave a sharp, metallic ping that rang against the brick conduit.

"Easy, copper-ears," I murmured, sliding my thumb into the pocket. I touched a dab of cold mutton fat against the escapement teeth, smoothing the vibration before the sound could travel up the stone. Pipu settled back, giving a contented mechanical shudder.

I looked out along the gorge. Morning mist was trapped between the sheer limestone walls, hovering over the water like a thick down quilt. Because the southern cliff rose thirty feet higher than the bridge deck, the wind draft curled backward off the stone face, creating a slow, circular eddy of river vapor between the two bluff positions.

It was an amphitheater built by nature itself. If a projection source were placed fifty yards upstream in the sunken dry wash, the widening brass baffle I had filed this morning could blanket that entire pocket of circulating fog without casting a single telltale beam toward the road. A luminous image cast into that cold eddy would seem to step directly out of the river, fifty paces above the water, blocking both bridgeheads at once.

Between the captive river mist and the widened dispersion baffle, the stage was ready.

Then the sharp snap of dry pine echoed from the eastern gun platform.

Directly above my culvert, an eighteen-year-old artillery loader in a gray tunic had stepped out from behind a gabion. His hands shook so violently that his brass ramrod clattered against the wheel hub. In his right hand, he held a glowing slow-match cord, its tip smoldering red in the morning gloom.

"Sir!" the boy gasped, voice cracking with terror as the western steam engine blew a loud vent of white exhaust. "They’re building pressure! The iron snout is turning toward the battery!"

"Hold your fire, boy!" Danladi yelled, but his voice was drowned by the hiss of the opposing boiler.

The young loader froze, the glowing slow-match cord clutched in a trembling fist three paces back from the breech. The ember flared cherry-red in the river draft, the boy shivering so violently his knees knocked against the carriage cheek, his white-knuckled grip caught between the captain's shout and the iron beast across the planks. The standoff hung on a fraying thread, but neither officer had given the final word.

There was no time to reason with two frightened commanders across eighty feet of open air, and no time to fetch help from the valley. If the bridge was going to survive the morning, the fear on those bluffs needed an answer larger than cannons.

I backed out of the culvert on silent elbows, slipping through the cold canal reeds until the steep mud banks hid the bridge towers behind me.

In the sunken wash fifty yards upstream, the world was still quiet. Kishi stood peacefully under the brambles, grinding clover between her molars while the distant shouting bounced harmlessly over her long ears. Beside her, beneath the coarse tarps of The Gilded Moth, the projector's brass fittings held the chill of dawn, smelling faintly of clean pine resin and cured iron.

I pulled back the canvas, letting my fingers rest against the cold valve wheel. Above the gorge, the circular bank of river mist continued its slow, silent rotation between the cliffs, an eighty-foot wall of white vapor waiting for the lantern to wake.
