Shan Chongguo vs Zhou Yu

Zhao Chongguo led a Han army against the Qiang tribes in the Hexi region. Using the tuntian system to supply his troops, he defeated the Qiang and secured the Han frontier, demonstrating the effectiveness of his agricultural colony strategy.

Zhao Chongguo proposed establishing military agricultural colonies (tuntian) in the Hexi Corridor to supply Han forces fighting the Qiang tribes. This system allowed soldiers to farm during peacetime, reducing the cost of long-distance supply lines.

Zhao Chongguo submitted a detailed memorial to Emperor Xuan advocating for the permanent establishment of tuntian colonies. The emperor approved the plan, leading to the long-term settlement of Han soldiers in the frontier regions.

Zhou Yu, as commander of Sun Quan's forces, allied with Liu Bei to confront Cao Cao's northern fleet on the Yangtze River. Using fire ships, Zhou Yu's smaller navy destroyed Cao Cao's larger fleet, preventing a southern conquest and securing the Three Kingdoms division.

After Red Cliffs, Zhou Yu led Sun Quan's forces in a year-long siege against Cao Cao's garrison at Jiangling. Zhou Yu was wounded by an arrow during the campaign. The eventual capture of Jiangling expanded Sun Quan's territory into Jing Province.

Zhou Yu died at age 36 in Yueyang while preparing a campaign against Liu Bei's ally Liu Zhang. His death removed a key strategist from Sun Quan's court and allowed Liu Bei to consolidate control over Jing Province.
