Lian Po vs Meng Tian

Lian Po led Zhao armies to victory against the state of Qi, capturing several cities. This campaign expanded Zhao's territory and demonstrated his military prowess as a general.

Lian Po, a veteran general of Zhao, initially resented Lin Xiangru's promotion above him. After learning of Lin's selfless behavior for the state, Lian Po apologized by carrying a thorny stick to Lin's residence, and the two became close allies.

King Xiaocheng of Zhao replaced Lian Po with Zhao Kuo as commander at the Battle of Changping, against the advice of Zhao She. Lian Po's defensive strategy was abandoned, leading to a disastrous defeat for Zhao.

Meng Tian led a Qin army to defeat the Xiongnu, driving them out of the Ordos region. This victory secured the northern frontier and allowed for the expansion of Qin territory.

Meng Tian oversaw the construction and reinforcement of the Great Wall of China, connecting and extending existing walls to defend against northern nomadic tribes. This project involved hundreds of thousands of laborers.

Meng Tian supervised the construction of the Straight Road, a 700-kilometer highway connecting the Qin capital Xianyang with the northern frontier. This road facilitated military movement and communication.

After the death of Qin Shi Huang, the eunuch Zhao Gao conspired to have Meng Tian forced to commit suicide. Meng Tian complied, despite his loyalty to the Qin dynasty. His death weakened the dynasty's northern defenses.
