The "Linked Horse Cavalry" in Water Margin: Huyan Zhuo's Tactical Weapon and the Way to Break the Game

Brief Introduction

The "Linked Horse Cavalry" is a highly representative tactical unit in the classical masterpiece Water Margin, primarily commanded by the imperial general Huyan Zhuo. This was not ordinary cavalry charging, but rather a heavy cavalry tactic where warhorses were connected by iron chains and both men and horses were clad in heavy armor. In the plot of the novel, the appearance of the Linked Horse Cavalry marks an escalation in the military crisis facing Liangshan Marsh. It serves as a key turning point for Song Jiang and his companions as they transition from outlaw bands to a formal military organization.

Core Knowledge Points

1. Tactical Formation: The Linked Horse Cavalry was typically organized in groups of three horses connected by iron chains or shackles. This formation made it difficult for the cavalry to be separated during a charge, forming a solid moving fortress.
2. Equipment Features: The warhorses were draped in iron armor, and the cavalrymen wore heavy armor while wielding long spears. This configuration greatly enhanced defense and impact power, making ordinary swords and blades unable to penetrate their defense.
3. Tactical Advantages: On flat terrain, the charge of the Linked Horse Cavalry was unstoppable. It could effectively counter Liangshan's infantry and light cavalry, creating immense psychological deterrence.
4. Fatal Weakness: Because the horses were linked, if one horse was injured and fell, the others would topple over as well. Additionally, their mobility was poor, making them ill-suited for complex terrain.
5. The Solution: The key to defeating them revealed in the book was the specially crafted weapon known as the Hooked Sickle Spear. This spear technique targeted the horse's legs specifically. When combined with pit traps, it could cut the iron chains and dismantle their formation.

Connection to the Book's Content

In Chapters 57 to 59 of Water Margin, after Liangshan Marsh defeated Grand Marshal Gao, Emperor Huizong dispatched Huyan Zhuo to lead troops in a campaign against them. Huyan Zhuo achieved initial victory, using the Linked Horse Cavalry to crush Liangshan, plunging leaders like Song Jiang and Chao Gai into a desperate situation, resulting in significant casualties.

The key to breaking the deadlock was the appearance of Xu Ning. Xu Ning was an instructor of the Golden Spear Class in Tokyo (Kaifeng) and was proficient in the Hooked Sickle Spear technique. Wu Yong devised a plan to steal Xu Ning's Yanling Armor (Goose-Feather Armor) and trick him into coming up the mountain. After Xu Ning arrived at Liangshan, he taught the Hooked Sickle Spear technique and formulated a strategy: set up pit traps on flat ground, and when the Linked Horse Cavalry charged in, use the hooked spears to sever the horses' legs. Ultimately, the Liangshan heroes successfully defeated Huyan Zhuo and captured the Linked Horse Cavalry. After this battle, Huyan Zhuo was captured following his defeat. After being persuaded by Song Jiang, he eventually submitted to Liangshan and became one of the Five Tiger Generals of the Cavalry.

Historical and Literary Significance

The Linked Horse Cavalry did have a prototype in history, originating from heavy cavalry tactics during the Song-Liao wars. However, in the novel, it was artistically exaggerated to become a core prop driving the plot. It symbolizes the powerful combat capability of the imperial regular army, contrasting with the growth process of the Liangshan heroes who defeated strong enemies through wit rather than brute force. This embodies the military wisdom in Water Margin of "meeting soldiers with generals, and water with earth" (adapting countermeasures to specific challenges).
