Jin Army Heavy Cavalry Armor System

Timeline

1. 1161Shouchun (present-day Shouxian, Anhui) · Huai WestWanyan Liang led the main force south from Shouchun; the Iron Pagoda heavy-armored cavalry, as elite bodyguard troops, accompanied the campaign, both horse and rider in heavy armor, tasked with frontal assaults on Song defensive lines, forming an infantry-cavalry coordinated offensive with Guazima on the flanks.
2. 1162–1164Zhongdu (present-day Beijing) · North ChinaJin heavy armor was mainly woven from willow-leaf plates with layered long armor strips encircling the body; helmets were double-layered with neck guards. Armor supplies largely came from spoils of war against Liao and Song; the History of Jin records that 550,000 sets of armor were captured in the Battle of Yanshan, supporting the equipment of elite cavalry.
3. 1165–1167Jin garrison areas north of the Huai River · Huai River BasinThe Iron Pagoda specialized in frontal assaults, sacrificing mobility for protection; Guazima were deployed on the flanks for outflanking maneuvers. Yang Ruyi's Record of the Victory at Shunchang states that Wuzhu's 3,000 bodyguard troops were 'all in heavy armor and full equipment, called Iron Pagoda by the enemy,' reflecting the core position of this armor system in Jin tactics.
4. 1168–1170Garrison sites of stationed cavalry in the circuits of North China · North ChinaAfter the 1164 Longxing peace treaty, the Jin army maintained heavy cavalry formations in North China; because of its high cost, the Iron Pagoda armor system remained limited to Jurchen elites—small in number but still an important symbol of Jin military deterrence against Song.
