Location and Strategic Importance
- Northern gateway: Capturing the pass allowed the Golden Horde Khanate’s main army to enter and plunder the empire’s northern provinces 10.
- Mountain frontier: The imperial–khanate border stretched for more than ten thousand li, but mountains made most of it unsuitable for large armies. Smaller paths remained usable by smugglers and raiding parties 24.
- Obstacle to invasion: Small Tuwu forces could bypass the pass, but the khanate’s main army could not safely advance south while leaving the fortress threatening its rear 10.
- Regional administration: The pass nominally belonged to Dragon Spine Province but operated independently in military matters. Governor Steele could neither appoint its generals nor direct its border defenses 15.
- Distance from Victor’s army: The Third Supplementary Army’s position near the Dragonbone Mountains was a little over one thousand li away 24.
Defenses and Garrison
The pass’s reputation rested on strong walls, artillery, magical protection, and extensive reserves; corruption had severely compromised several of these defenses before the siege 21 24.
| Component | Intended Strength | Condition During the Siege |
|---|---|---|
| Fortress walls | Old, sturdy construction forming the core of the pass’s physical defenses 21. | Remained structurally dependable until the summoned Abyssal Demonic Dragon smashed a breach through them 21 22. |
| Magic crystal cannons | More than thirty cannons, publicly regarded as advanced defensive weapons 21 24. | None met the required standard. Four barrel bursts and five breakdowns occurred on the first day; the cannons were out of action by the third day 21. |
| Anti-magic domain | An expensive defensive field officially claimed to withstand roughly ten forbidden spells 24. | Failed after stopping a single enemy attack, leaving the fortress without its intended magical protection 21. |
| Mage force | Provincial mages were conscripted after the Northern Frontier Corps lost its eight-hundred-mage unit 21. | Mostly low-tier mages powered magic arrays, then had to pause to recover their magic power 21. |
| Stored equipment | Weapons and equipment stockpiled for the defenders 21 24. | More than ninety percent of the stored weapons and equipment were substandard 21. |
| Provisions | Victor understood the reserves to be sufficient for a siege lasting one or two years 24. | The fortress fell after just over a month, before such endurance could be tested 22. |
Troop Strength
| Period | Reported Strength |
|---|---|
| Before provincial reinforcements | Approximately ten thousand defenders and a few thousand survivors of the Northern Frontier Corps 10. |
| After local mobilization | Victor understood that the assembled force had reached two hundred thousand to three hundred thousand, including nearby troops and nobles’ private armies 25. |
- Emergency defenses: Once the artillery failed, soldiers relied on dropped stones, rolling logs, and boiling excrement 21.
- Reserve deployment: Griffin ordered reserves to stand ready to seal any breach in the walls 21.
- Reinforcement quality: Steele mobilized provincial nobles’ private armies, though many contributed numbers rather than substantial fighting strength 10.
History
Earlier Tuwu Attacks
Before the current invasion, the Tuwu People had last broken through Dragon Spine Pass fifty years earlier. During the intervening decades, their southern raids generally used small forces that bypassed the fortress 12.
The pass consequently acquired a reputation for near-impenetrability. Even during the crisis, Victor expected the foremost northern stronghold to withstand at least half a year of siege 23 24.
Encirclement and Failed Negotiations
Duke Alvin’s catastrophic defeat on the grasslands destroyed the empire’s forward defensive position and left Dragon Spine Pass in immediate danger. Alvin withdrew into the fortress, but the enemy quickly surrounded it, cutting short efforts to gather routed soldiers. The empire removed him from command and placed the defenses under Lieutenant General Griffin 4 7.
The khanate initially debated whether to storm the pass or demand reparations. Marshal Slate favored an assault, while Chancellor Oliver warned that attacking its fortifications under magic crystal cannon fire could cost tens of thousands—or more than one hundred thousand—soldiers. High Priest Blackwood supported waiting for the empire’s final response 10.
Inside the pass, Steele prepared provincial reinforcements while Griffin and Alvin argued over the enemy’s demands. In the capital, repeated disputes over deployment, logistics, and finance delayed the wider response. After a month of meetings, the court was still debating a major reinforcement plan and an additional war tax on freemen 10 20.
Siege and Fall
The opening fighting inflicted thousands of casualties on the khanate in a single day. However, defective cannons repeatedly exploded among the defenders, frightening crews into stopping their work. The artillery’s eventual loss and the failure of the anti-magic domain stripped away two of the fortress’s principal advantages 12 15 21.
The attackers then used a forbidden summoning ritual. Hundreds of priests sacrificed tens of thousands of prisoners to summon the Great Abyssal Demonic Dragon, whose claw struck the wall and killed countless defenders. The creature opened a breach, allowing Tuwu troops to pour into the fortress 21 22.
Dragon Spine Pass fell after holding out for just over a month. Blackwood died from the ritual’s backlash, and Great Khan Silas ordered his death concealed during the capture 22.
Demolition and Aftermath
Silas ordered the captured pass stripped completely and every building demolished. Destroying it was both a military measure and a political declaration that the barrier to southern expansion had been removed. By the later debate over withdrawal, the khanate’s leaders confirmed that demolition was complete and estimated that imperial repairs would take at least two years 24 34.
The fall exposed Dragon Spine Province to extensive plundering and forced the imperial court to organize local defenses and rewards for killing Tuwu warriors. It also ruined Victor’s plan to return home through paths near the pass, prompting him to seek a western route toward the Andorra Peninsula 22 24 25.
The victory freed khanate troops for operations elsewhere, including the Seventh Tumen’s return to the grasslands against Victor’s army 24 26.
Responsibility for the Defeat
When questioned by Marshal Sebastian, Alvin distinguished his own battlefield defeat from the loss of the pass, citing corruption, poor coordination, logistics, and defective defenses. Griffin emphasized the enemy’s summoned dragon instead 30 31.
Griffin had himself benefited from corrupt dealings involving the fortress. The defensive failures had gone undetected because he followed earlier commanders’ practices rather than properly inspecting the equipment and installations 31.
