Innovative Mongol Warfare Tactics

Key Insight

Against fortified cities, which the Mongols initially lacked the conventional means to conquer, Genghis Khan's fundamental strategy was to secure victory before the first arrow was shot, by instilling confusion and fear. Their approach involved wreaking havoc in the surrounding countryside, then disappearing only to reappear, creating uncertainty. They masterfully exploited internal social divisions, such as portraying themselves as liberators to the Khitan, who shared ethnic ties, and undermining the Chinese subjects' faith in Jurched defense. This propaganda led to numerous Khitan defections, and by 1212, Genghis Khan formally established the Khitan monarchy as a vassal state, further fragmenting Jurched power.

The Mongols ingeniously transformed the Jurched's large population into a strategic vulnerability. Each Mongol warrior conscripted ten local men to provide food and water for the army and animals, and to gather materials like stones and dirt for filling moats during sieges. These captives also operated siege engines and movable towers. Peasants, often viewed as 'grazing animals,' were driven from their villages, creating over 1000000 refugees who clogged highways, consumed urban food supplies, and caused widespread chaos. These displaced populations were also directly employed as human shields and living battering rams against city gates; their bodies filled moats, reflecting the Mongol's disregard for enemy lives when preserving their own. This led to internal strife, including cannibalism, urban mutinies, and peasant rebellions, culminating in the Jurched army killing 30000 of their own peasants.

Mongols waged warfare across entire territories, leveraging ensuing turmoil with clever trickery. Examples include a Mongol officer disguised as a high-ranking official dismantling a besieged city's (Dading) defenses, or an apocryphal story of releasing fire-laden cats and birds into a city. For direct assaults, formations like the Crow Swarm or Falling Stars involved horsemen galloping from all directions simultaneously, creating immense confusion before a sudden disappearance. They rapidly adopted Chinese siege technology, including catapults, trebuchets, and ballistas, forming permanent engineering units staffed by captured engineers. They also used the firelance and feigned retreats, known as the Dog Fight tactic, as seen at Liaoyang, where they left equipment to lure enemy soldiers out before rushing the opened city gates. When pursued, Mongols used diversions like strewing valuable items or creating dust clouds with tree branches tied to horses' tails to obscure their numbers.
