Building a Viking Empire with Modern Industry-Chapter 247: Fall of Caesarea

The Anatolian Plains, Abbasid-Byzantine Frontier

Bjorn walked slowly through the drifting ash.

The sprawling agricultural settlement on the outskirts of the Anatolian plains had been reduced to a smoldering graveyard.

The irrigation trenches were choked with debris, and the local Arab peasantry lay scattered among the ruins, casualties of a brutal raid.

Since the Iron Empire’s mechanized forces had annihilated the Roman Cataphracts in the valley pass, the surviving Byzantine commanders had drastically altered their strategic approach. The slaughter had cured them of their arrogance.

They now understood, with terrifying clarity, that forming up in dense cavalry wedges to charge entrenched rifled artillery was tantamount to mass suicide.

But the Byzantine officers were seasoned veterans of frontier warfare, and they quickly identified the Iron Empire’s one glaring vulnerability: logistics.

Bjorn commanded an elite, technologically unparalleled force, but it was numerically small.

His detachment could hold the major regional strongholds and dictate the terms of any pitched battle, but they lacked the manpower to garrison the vast, sprawling farmlands of the Anatolian expanse.

The Romans, realizing they could not break the Viking guns, had decided to starve them.

They had splintered their remaining forces into highly mobile, lightly armored raiding parties, initiating a ruthless campaign of scorched-earth guerrilla warfare.

Captain Ulf stepped through the smoking ruins of a collapsed barn, his face masked in a fine layer of gray soot. He held a repeating musket loosely in one hand, his jaw set in a hard, grim line.

He stopped beside his commander and looked out over the devastated valley.

"This is the fourth village this week," Ulf said,

"They aren’t even taking the grain anymore. They are just burning it in the silos. Slitting the throats of the draft animals and poisoning the wells."

Bjorn knelt in the dirt, picking up a handful of scorched wheat.

"It is a sound strategy," he murmured. "They cannot pierce our armor or survive our guns. So, they attack our ledgers. An army of this size, heavily reliant on draft horses to move artillery carriages, consumes tons of forage a day. If the breadbasket burns, the Vanguard starves."

"It is a coward’s war," Ulf replied, "They strike at undefended peasants and flee before our outriders can even mount up. We formally placed these settlements under the protection of the Lion Banner. Allowing the Byzantine remnants to operate like this is a slight to the Iron Father. We must retaliate, Commander. If we do not project strength, the local populace will turn against us, believing we cannot defend the lands we conquer."

Bjorn stood, dusting his hands off on his heavy coat. He looked westward, toward the jagged horizon. He spent several long moments running the tactical variables through his mind.

The Byzantine raiders were too fast and too dispersed to hunt down individually.

Chasing them across the Anatolian plains would exhaust his horses and wear down his men. He needed a central, undeniable target to force a political capitulation.

"If the Byzantine Emperor wishes to reduce our supply lines to ash," Bjorn finally said, "then we will introduce him to the true cost of asymmetric warfare. Send word to the quartermasters. Recall the outriders. We are breaking camp."

Ulf looked at him, recognizing the shift in his commander’s demeanor. "Where are we marching?"

"To Caesarea," Bjorn replied. "The provincial capital. If they attempt to starve the Iron Empire, we will systematically dismantle the foundational architecture of their civilization."

***

Bjorn’s decision was not born of spontaneous anger, but of cold, calculated protocol.

Total, disproportionate psychological terror was a strategic deterrent formulated by King Ragnar long before the Vanguard had ever crossed into the Middle East.

It was known among the high command as the Doctrine of Decimation.

The Doctrine was a formalized, industrialized military policy designed to compensate for the Iron Empire’s limited early manpower. It operated on a strictly mathematical premise: if an enemy engaged in sabotage, asymmetrical warfare, or the deliberate destruction of Iron Empire logistics, the Viking forces would not respond by hunting the perpetrators.

Instead, they would systematically target the enemy’s most valuable civilian, economic, or cultural centers, inflicting a tenfold return of destruction.

In the eyes of traditional military minds the Doctrine was a horrific violation of the rules of war. But King Ragnar was a sovereign of extreme pragmatism.

He despised the grueling inefficiency of prolonged guerrilla conflicts. He understood that a technologically inferior enemy could bleed a superior force dry over decades of hit-and-run attacks.

The only way to stop a decentralized insurgency was to make the cost of that insurgency unbearable for the enemy’s leadership.

Bjorn was acutely aware of this imperial mandate. To permit the systematic massacre of the local agrarian population without executing a cataclysmic retaliation would be viewed as a failure of command. He had to demonstrate that the Iron Empire’s capacity for violence extended far beyond the battlefield.

...

Over the course of the next two weeks, Bjorn’s expeditionary force crawled westward.

The Vanguard utilized massive, iron-reinforced oak carriages to transport their Bessemer steel cannons.

Each twelve-pounder and twenty-four-pounder gun required teams of twelve to sixteen heavy draft oxen to pull.

The summer heat was oppressive, baking the clay roads into hard, rutted tracks that continuously broke wooden spokes and snapped iron axles.

The march required absolute discipline. The captive Tang laborers and elite Viking engineers worked in grueling tandem, felling trees to reinforce crumbling stone bridges, laying corduroy roads over marshy river crossings, and winching the massive guns up steep inclines.

Bjorn kept the men moving from dawn until dusk, their progress marked by the dust clouds rising high into the suffocating summer air.

As they marched, the expeditionary force deliberately overran any minor Byzantine outposts or watchtowers in their path.

There were no negotiations and no prisoners taken.

The outposts were reduced to rubble by light field guns, ensuring that the Roman military infrastructure suffered the exact same fiery fate as the Abbasid villages they had torched.

Finally, on the seventeenth day of the march, the terrain leveled out, and the towering, ancient walls of Caesarea came into view.

Caesarea was the most prosperous Byzantine fortress city in the region. It was a masterpiece of medieval engineering.

Its massive, layered stone walls were immensely thick, designed to easily withstand the pounding of traditional catapults, trebuchets, and bronze battering rams.

Bastions jutted out at regular intervals, providing overlapping fields of fire for thousands of archers. In any previous century, a city like Caesarea could only be taken through a grueling, years-long starvation siege.

Bjorn intended to reduce it to gravel by nightfall.

The Vanguard did not dig the traditional zigzagging trench lines required for a conventional medieval siege.

They simply halted on a wide, elevated ridge a full mile and a half from the city’s outer gates, well beyond the maximum range of any Byzantine archer or ballista.

The setup was methodical and unnervingly quiet. Tang alchemists and Viking artillery officers unrolled heavy canvas maps and brass surveying instruments.

They measured the elevation of the ridge, the distance to the city walls, the barometric pressure, and the ambient wind speed.

The siege guns were unlimbered and rolled into a long, staggered firing line. The engineers worked with the practiced rhythm of a factory floor.

They dug deep recoil trenches behind each carriage, bracing the heavy wooden trails against the solid earth to prevent the guns from tearing themselves apart under the stress of firing...

Once the guns were secured, the loading sequence began. The alchemists weighed out exact measurements of highly purified corned black powder, sliding the silk bags down the rifled barrels.

The massive, conical iron shells were winched up and rammed tightly into the breeches, their soft lead driving bands perfectly engaging the spiraled rifling grooves inside the steel tubes.

Bjorn stood atop a rocky outcropping, a brass-rimmed spyglass pressed to his eye.

He could see the tiny, armored figures of the Byzantine defenders scrambling frantically along the tops of the walls.

They were preparing vats of boiling oil and hauling up heavy stones, completely failing to realize that the Viking infantry had no intention of ever bringing a scaling ladder to their walls.

Bjorn lowered the glass. He checked his pocket watch, noting the time. He turned to Captain Ulf, who stood waiting by the command tent.

"Commence the bombardment," Bjorn ordered.

Ulf raised a red signaling flag and dropped it sharply.

The ridgeline erupted. The simultaneous detonation of twenty heavy siege cannons physically shook the bedrock.

A massive, concussive wave of overpressure rolled across the plains, flattening the tall grass and kicking up a blinding cloud of white, sulfurous smoke. 𝓯𝓻𝒆𝙚𝒘𝓮𝙗𝓷𝒐𝓿𝙚𝒍.𝙘𝓸𝙢

The massive guns violently kicked back into their recoil trenches, the iron wheels churning the dirt.

Seconds later, the aerodynamic shells struck the walls of Caesarea.

The impact was not a singular dramatic explosion, but a series of deep, structural concussions.

The high-explosive shells, fitted with delayed-action fuses, did not shatter against the exterior of the stone. Instead, the hardened steel caps punched deep into the ancient masonry before detonating from within.

Through the clearing smoke, Bjorn watched as a sixty-foot section of the outer wall visibly bulged outward.

A moment later, the entire structure gave way. Thousands of tons of ancient, meticulously carved limestone cascaded down into the moat, taking hundreds of Byzantine defenders with it in a blinding cloud of pulverized dust.

The artillery crews did not pause to admire their work. They immediately swabbed the smoking barrels with wet sponges, loaded the next precise charge of corned powder, and slammed the breeches shut.

The officers adjusted the elevation screws slightly, recalibrating their coordinates, and pulled the lanyards again.

...

The bombardment continued without pause for six agonizing hours.

Bjorn stepped back from the firing line, seeking brief refuge from the deafening thunder of the guns.

He felt a strange, hollow sense of mechanical detachment settling over him.

War, for all its horrors, had always possessed a grim, terrible humanity.

He looked down the line of his artillery crews. Men with soot-stained faces pulling lanyards, loading shells, swabbing steel.

With the pull of a string, they were vaporizing ancient architecture and erasing thousands of lives from over a mile away.

There was no courage required, no clash of steel, no honorable exchange of ransoms.

The Iron Empire had stripped the battlefield of its ancient romance, replacing it with a cold, emotionless algorithm of explosive yields and trajectory physics.

Bjorn knew it was necessary. If the Romans had simply surrendered in the valley, this could have been avoided. But their refusal to accept the reality of industrial progress had forced his hand.

Some of the younger, more bloodthirsty mercenaries in the detachment cheered every time a tower collapsed in the distance.

By the time the sun dipped low against the western horizon, casting long shadows across the Anatolian plains, Caesarea was effectively erased.

The ceaseless, rhythmic pounding of the siege guns had reduced the legendary provincial capital to a smoldering, unrecognizable crater of ash, shattered masonry, and splintered timber.

Fires raged unchecked through the interior of the city, sending a massive, twisting pillar of black smoke high into the evening sky.

The political and economic heart of the Byzantine frontier was gone.

The message had been delivered. The Doctrine of Decimation had been fulfilled.

The leaders in Constantinople would soon receive word that the cost of burning a few Abbasid wheat fields was the total annihilation of their greatest fortress city.

It was a permanent, terrifying stain on their martial pride, a geopolitical wound that would take decades to heal.

Bjorn ordered the guns to cease fire. The sudden silence that fell over the ridge was absolute, ringing loudly in the ears of the exhausted artillerymen.

"Limber the guns," Bjorn called out, his voice hoarse from the dust.

"Check the axles and water the oxen. We march at first light."

Captain Ulf approached, wiping his brow with a filthy rag.

"Where to next, Commander? Back to the Abbasid strongholds?"

"Our retaliation is complete, but the campaign is not. We made a promise to the King. The Vanguard marches west. We are going to the Levant." Bjorn replied, turning his gaze toward the setting sun.

Bjorn knew that far away from these burning deserts, King Ragnar was entrenched within the smog-choked, heavily fortified walls of City Titan.

The Iron Father was tirelessly expanding his industrial base, laying hundreds of miles of iron rail, and constructing the massive, steam-powered ironclads that would soon project his power across the oceans. But those ships needed a deep-water harbor.

They needed a logistical anchor in the Middle East.

Bjorn mounted his heavy warhorse, feeling the familiar, reassuring weight of his saddle. He had executed the cruel mathematics of modern warfare flawlessly.

He would likely be awarded the highest honors of the Empire for the destruction of Caesarea.
