Building a Viking Empire with Modern Industry-Chapter 246: Byzantine Cataphracts?

The Anatolian Plains

The smoke from the burning Abbasid fortress drifted thick and low across the sun-baked plains of the Anatolian frontier.

The clatter of the Byzantine Cataphracts filled the air as the massive cavalry force continued its methodical advance. At the vanguard sat Strategos Bardas, watching the subjugation of the fortress from the elevated vantage point of his armored warhorse.

Miles of wooden carts groaned under the weight of the morning’s plunder. Columns of chained prisoners were being marched out of the city gates, flanked by Byzantine infantrymen. Bardas wiped a layer of pale dust from his breastplate and surveyed the victory.

It had been a brief, brutal siege, and the remaining Abbasid garrisons in the region were collapsing with predictable efficiency.

A few yards away, the enslaved Arab garrison commander, Emir Tariq, knelt in the churning mud. His armor had been stripped, and his hands were bound tightly behind his back. He did not weep, though his face was bruised and streaked with coagulated blood.

He looked up at the mounted Strategos,

"We have surrendered the city," Tariq said, "We offer no further resistance. I ask only that you honor the terms of surrender and spare the non-combatants."

Bardas looked down at the defeated Emir, his expression flat and thoroughly unimpressed.

"Terms are dictated to those who have the power to refuse them," Bardas replied calmly. He motioned to his guards. "Put the wounded to the sword. Process the rest for the slave markets in Constantinople. We march within the hour."

Tariq lunged forward with a desperate cry, but a guardsman stepped in, delivering a swift, crushing blow to the Emir’s shoulder with the haft of a spear. Tariq collapsed into the dirt, gasping in pain as he was dragged away toward the holding pens.

Bardas turned his horse back toward the main column. "Dress the lines!" he called out to his heralds. "We push forward. The Caliphate is broken, and Baghdad is unprotected."

The Roman Cataphract was the undisputed heavy shock force of its era.

Both the selectively bred warhorses and their elite riders were encased entirely in overlapping steel lamellar plates. When thirty thousand of these heavy cavalrymen charged in a synchronized wedge formation, the sheer kinetic weight of the assault could shatter the most disciplined infantry lines in moments. For centuries, traditional spear walls and archer formations had proven wholly inadequate against the sheer mass of a Cataphract charge. Bardas knew this, and he intended to ride that momentum all the way to the Abbasid capital.

As the army formed up, a young Byzantine lieutenant named Leon rode up alongside the Strategos. Leon looked exhausted. His wide eyes constantly scanned the shimmering, heat-distorted horizon, and a sheen of sweat coated his neck beneath his heavy helmet.

"My Lord Strategos," Leon began, holding up a rolled parchment map. "Our forward scouts have returned. The Abbasids have entirely abandoned the regional fortifications ahead. They have retreated into the distant hills, leaving the main valley pass completely open."

Bardas raised an eyebrow. "Then the path is clear. Why do you look like a man stepping onto the gallows, Tribune?"

"Because we are overextending, sir," Leon urged, pointing a gauntleted finger toward the vast expanse of flat terrain ahead. "By pushing our heavy cavalry this deep into the valley, we are stretching our supply lines dangerously thin. The enemy is offering no resistance and leaving the perfect terrain for a cavalry charge entirely undefended. It is too convenient. We should halt, consolidate our gains, and establish a defensive perimeter before entering that pass."

Bardas let out a short, dismissive breath. "Consolidate? The enemy is routing, Tribune. They abandon the plains because they know they cannot withstand a heavy cavalry charge on open ground. That valley is a tactical gift. It gives us the unobstructed terrain we need to maintain formation and build charging speed. If we stop to dig trenches like frightened infantrymen, we give the Caliphate time to regroup."

Leon bowed his head, recognizing the finality in his commander’s voice. He fell back into the ranks, his stomach tight with a dread he couldn’t entirely articulate.

The Byzantine army marched forward, thirty thousand horsemen riding blindly into the new age of warfare.

They were entirely unaware of the industrialized reality waiting for them. The wide-open path, which looked to Bardas like a glorious highway for his cavalry, was a meticulously engineered trap. Vanguard Commander Bjorn and the Iron Father’s strategists understood the fundamental mechanics of heavy cavalry. Horsemen require flat, unobstructed terrain to maintain their formations and leverage their speed.

However, flat terrain devoid of natural cover is also the optimal environment for artillery.

By abandoning the hills and drawing the Byzantines onto the valley floor, the northerners had created a mathematically perfect kill box. The Byzantine commanders believed they were dictating the terms of the engagement; in reality, they were marching their densely packed formations straight into a mechanized firing range.

High above the valley floor, concealed along the rocky ridges beneath perfectly woven camouflage netting, the Iron Empire’s forces worked in disciplined silence.

Elite Viking engineers and captive Tang laborers had spent the last three days securing the high ground flanking the pass.

They had bolted heavy, Bessemer steel rifled cannons directly into the solid bedrock, bracing the carriages against the immense recoil they were about to produce. The Tang alchemists had already calculated the elevation angles, wind resistance, and powder charges necessary to cover the valley in a crossfire of overlapping artillery fields.

Vanguard Captain Ulf, a towering, battle-scarred Viking entrusted with the ambush, lay on his stomach at the edge of the ridge. He peered through a brass-rimmed spyglass, watching the metallic tide of Byzantine cavalry pour into the mouth of the valley.

"They march in a packed wedge," Ulf murmured to his lieutenant, lowering the glass. "Shoulder to shoulder. No skirmishers on the flanks. No scouts scaling the ridges."

"They rely on their armor," the lieutenant replied quietly.

"Armor," Ulf said, resting his hand on the cold steel breech of a twelve-pounder cannon. "Against this. It is almost a pity."

A few feet away, Master Wei, the senior captive alchemist, was making final adjustments to the firing mechanism. His hands were stained with soot, but they did not tremble as he worked. The weapon before him was a masterpiece of metallurgy. Forged from a single billet of hyper-purified steel, the barrel featured precisely carved internal spiraling grooves.

When fired, the expanding gases of the corned powder would force the aerodynamic iron shell to grip the grooves, imparting a violent spin to the projectile as it exited the muzzle. This gyroscopic stabilization turned the weapon from an inaccurate siege bombard into a lethal, long-range rifle. The technological gap of centuries had been bridged, and it was currently pointed directly at the Byzantine vanguard.

Wei carefully packed the purified corned powder into the chamber, inserted the conical shell, and locked the heavy steel breech closed with a solid, metallic clack. He stepped back and nodded to Ulf.

Down on the valley floor, the Byzantine army reached the exact center of the pass. Strategos Bardas drew his sword, preparing to signal the final push through the valley toward the Abbasid interior.

"Sound the advance!" Bardas called out to his horn blowers.

Before the heralds could draw breath, the ridges on both sides of the valley erupted.

"Fire," Ulf commanded quietly.

Fifty rifled cannons fired in near-simultaneous succession. The concussive shockwave of the synchronized blast tore through the air, completely shattering the quiet of the Anatolian plains. Billowing clouds of acrid white smoke masked the ridges, instantly filling the high air with the smell of sulfur.

Because the artillery was positioned miles away, the Byzantine cavalry saw the flashes of fire on the ridges seconds before the sound reached them.

Then, the shells arrived. The armor-piercing projectiles struck the tightly packed ranks of the Cataphracts with a kinetic force that defied medieval comprehension. These were not solid iron balls meant to bounce through infantry lines.

They were high-explosive, timed-fuse fragmentation shells packed with hyper-purified black powder and deeply scored iron casings.

They detonated mid-air, directly above and among the heavy cavalry.

The casings violently shattered, projecting tens of thousands of jagged shrapnel fragments outward at supersonic speeds. The vaunted lamellar armor of the Cataphracts, designed to deflect arrows and spear thrusts, offered absolutely no resistance to industrial fragmentation.

The dense, disciplined formation was instantly transformed into a slaughterhouse.

The destruction was methodical and absolute. Heavy warhorses were cut down in their strides, collapsing in bloody heaps that tripped the riders behind them. Elite cavalrymen were shredded by shrapnel before they could even identify where the attack was coming from. The continuous, rolling thunder of the bombardment drowned out the screams of the dying.

A shell detonated thirty yards from Strategos Bardas. The concussive wave threw him violently from his saddle. He crashed into the dirt, his heavy armor pinning him for a moment as the wind was knocked from his lungs.

Gasping for air, his ears bleeding from the overpressure of the blasts, Bardas pushed himself up onto his hands and knees. He looked around in a state of profound, paralyzing shock. His invincible vanguard was evaporating. Men and horses were being torn apart by an invisible, deafening force raining down from the empty hills.

Nearby, Tribune Leon knelt in the dirt behind the corpse of his horse, his hands pressed tightly over his ears. He had warned his commander about the valley, but his tactical anxieties had been rooted in the fear of hidden archers or a conventional infantry ambush.

Nothing in his education or experience could have prepared him for the industrialized devastation tearing his army apart.
