Liu Guangshi vs Tan Lun

Liu Guangshi commanded Song forces that defeated a Jin army at Yancheng, using combined infantry and cavalry tactics. The victory boosted Song morale but was not followed up due to peace negotiations.

Liu Guangshi was a key negotiator in the Shaoxing Treaty between the Southern Song and Jin dynasties. The treaty established the Huai River as the border and required Song to pay annual tribute, ending active warfare.

After the Shaoxing Treaty was ratified, Liu Guangshi retired from military service, possibly due to court politics. His retirement marked the end of active Song resistance against the Jin for decades.

Tan Lun was appointed to command coastal defenses in Zhejiang and Fujian provinces against Japanese pirates (Wokou). He organized local militias and coordinated with General Qi Jiguang, implementing new tactics to counter pirate raids.

Tan Lun worked closely with General Qi Jiguang in a series of campaigns against the Wokou pirates. Their combined forces achieved several decisive victories, significantly reducing pirate activity along China's southeastern coast.

Tan Lun was appointed Minister of War in the Ming central government. In this capacity, he oversaw military reforms and border defense policies, including the strengthening of the Great Wall defenses against Mongol incursions.

As Minister of War, Tan Lun oversaw the construction and reinforcement of Great Wall fortifications in the northern border regions. These defensive works included watchtowers, garrison stations, and improved walls, aimed at deterring Mongol raids.
