The Decline of Chariot Warfare in Ancient China

For over a year, Che Ying had been entrusted with the monumental task of training Qin’s new army. The reformed forces now consisted of only 30,000 armored cavalry and 20,000 heavy infantry—a fraction of Qin’s former military strength.

This shift marked a dramatic departure from the Zhou Dynasty’s traditional chariot-based warfare. During the Spring and Autumn period, Qin, under Duke Mu, had fielded over 5,000 chariots and nearly 200,000 troops, dominating the Central Plains. Chariot warfare, however, was costly and cumbersome. Each chariot required elite noble warriors, skilled drivers, and supporting infantry, making it an unsustainable system amid prolonged conflicts.

By the late Spring and Autumn period, chariots had become obsolete. States like Wei pioneered mixed infantry-cavalry formations, exemplified by Wei’s famed “Martial Infantry” (武卒), who could march 100 li (approx. 50 km) in full armor. Meanwhile, Qin, clinging to outdated chariot forces, suffered humiliating defeats against Wei’s modernized armies under Wu Qi.

The Military Reforms of Duke Xiao and Shang Yang

Recognizing Qin’s vulnerability, Duke Xiao and his chancellor Shang Yang initiated sweeping reforms. Their vision was clear: a lean, professional army capable of defeating Wei’s elite troops.

### Recruitment and Training

Che Ying implemented rigorous selection criteria:
– Strict Physical Standards: Recruits had to match Wei’s “Martial Infantry” endurance—wearing triple armor, carrying heavy weaponry, and marching 100 li.
– Social Mobility: Noble birth no longer guaranteed command. Promotions were merit-based, exemplified by Shan Jia, a former herb-gatherer’s son who rose to lead a thousand infantry.

### Equipment and Tactics

– Iron Weapons: Despite Qin’s iron scarcity, the state confiscated civilian iron to forge superior swords, spears, and crossbows.
– Cavalry Innovations: Chariots were replaced with nimble cavalry using narrow longswords for slashing attacks.
– Anti-Cavalry Tactics: Infantry units employed wooden mallets to crush horses’ armored heads—an innovation credited to Shan Jia.

The Grand Military Demonstration

In a secluded valley, Qin’s new army showcased its prowess:
– Cavalry Charges: 16,000 horsemen simulated flanking maneuvers.
– Infantry Resilience: 18,000 foot soldiers formed defensive circles, repelling cavalry with coordinated mallet strikes.
– Leadership: Che Ying, refusing special treatment, commanded from the front lines, embodying the army’s ethos.

Duke Xiao and Shang Yang watched in awe. The troops’ discipline—standing motionless for hours—proved their readiness.

Legacy and Impact

### Cultural Shift

– Merit Over Birth: Commoners like Shan Jia became officers, eroding aristocratic privilege.
– National Pride: Soldiers fought not for nobles, but for land grants earned through battlefield valor.

### Strategic Implications

Qin’s reforms laid the groundwork for future conquests:
– Defeating Wei: The new army’s victory at the Battle of Maling (342 BCE) shattered Wei’s dominance.
– Unification: This military machine, refined over generations, enabled Qin to conquer the Warring States by 221 BCE.

As Duke Xiao declared after the演练: “With this army, Qin’s rise is unstoppable.”
