Qi Jiguang vs Su Dingfang

Qi Jiguang recruited and trained a new army from the peasantry of Zhejiang province. He implemented strict discipline, innovative tactics, and specialized weapons, creating a highly effective force against Japanese pirates.

Qi Jiguang wrote 'New Treatise on Military Efficiency' (Jixiao Xinshu), a manual on military training and tactics. The book detailed his methods for organizing, equipping, and drilling troops, influencing later Chinese military thought.

Qi Jiguang led his army to a decisive victory against Japanese pirates at Cengang in Zhejiang. The battle destroyed a major pirate base and significantly reduced pirate activity along the coast.

Qi Jiguang was appointed to strengthen the Great Wall defenses against Mongol incursions. He rebuilt sections of the wall, added watchtowers, and trained garrison troops, improving border security for decades.

Su Dingfang participated in the Tang campaign against the Tuyuhun kingdom. The Tuyuhun were defeated and became a Tang vassal, securing the Tang's western frontier.

Su Dingfang led a Tang army to defeat the Western Turkic Khaganate at the Battle of Irtysh River. The khagan was captured, and the Western Turkic state was destroyed, extending Tang control over Central Asia.

After the conquest of the Western Turks, Su Dingfang suppressed a rebellion led by Ashina Helu, a former Turkic vassal. The rebellion was crushed, and Helu was captured, solidifying Tang control.
