In 200 CE, the Battle of Guandu was fought between Cao Cao and Yuan Shao during the Three Kingdoms Period.
Why did it happen?
Following the suppression of the Yellow Turban Rebellion in 184 CE, the authority of the Han emperors was significantly weakened. When Emperor Ling died in 189 CE, General Dong Zhuo seized power. Being a ruthless commander, Dong Zhuo’s authority was contested by other generals who had helped suppress the Yellow Turban Rebellion, and in 192 CE, he was assassinated, and Cao Cao took control of the imperial government. Like his predecessor, Cao Cao could not win the allegiance of the provincial warlords and constantly fought his rivals in northern China. By 200 CE, Yuan Shao controlled significant territory north of the Yellow River. When he sought to expand his power base south over the entire North China Plain, Cao Cao fortified his position at Guandu on the Yellow River to intercept his advance.
Who was involved?
Cao Cao’s forces at Guandu numbered 15,000 infantry and 5,000 cavalry. Despite being heavily outnumbered, Cao Cao’s forces were positioned in and around Gunadu and supplied ample food and resources to maintain their position. Cao Cao planned to raid Yuan Shao’s supply lines and destroy their grain stores at Wuchao, thereby demoralising and malnourishing Yuan Shao’s soldiers. Yuan Shao’s forces at Guandu numbered 60,000 infantry and 10,000 cavalry. Of this number, 60,000 were under the direct command of Yuan Shao, while Chunyu Qiong led the remaining 10,000. Chunyu Qiong planned to guard Yuan Shao’s logistical base at Wuchao while Yuan Shao led a direct assault on Guandu.
What happened?
Cao Cao led his cavalry under the cover of night to raid Yuan Shao’s supplies at Wuchao, which Chunyu Qiong guarded. When Yuan Shao learnt of Cao Cao’s attack on his supplies, he sent light cavalry to aid Chunyu Qiong. Yuan Shao then launched a full-scale assault on Guandu. Meanwhile, Cao Cao’s cavalry captured Wuchao and burnt its supplies, demoralising Yuan Shao’s troops. At the same time, Yuan Shao’s assault on Guandu was repulsed by Cao Hong, and Cao Cao ordered an assault on Yuan Shao’s camp, killing 69,200 of his soldiers. Yuan Shao escaped the battle with 800 cavalry.
What changed as a result?
The Battle of Guandu was a victory for Cao Cao. As stated by Nono Umasy, “The victory at Guandu was a monumental achievement for Cao Cao. It not only solidified his control over Northern China but also significantly weakened Yuan Shao, who was once considered the most powerful warlord in China” (Umasy, 2024). Yuan Shao’s influence declined rapidly, and in 201 CE, he was defeated again by Cao Cao at the Battle of Cangting before dying the following year. Cao Cao’s victory at Guandu paved the way for his future conquests, which, by 208 CE, united all of northern China under his rule. However, his defeat at the Battle of Red Cliffs meant that China would remain divided into three states, with Cao Cao ruling over the northern state until he died in 220 CE. China subsequently entered the Three Kingdoms Period, which would last until it was unified again under the Jin Dynasty in 280 CE.
