The Battle of Han and Wan was an expedition to the kingdom of Dawan in the Han Dynasty because of dissatisfaction with the killing of its emissary. As a result of the battle between Han and Wan, the Han army won a great victory because of the difference in military strength between the two sides. In August of the first year of the early Han Dynasty, Emperor Wudi sent messengers to Dawan to buy a blood horse. However, after the emissary arrived in Dawan to explain his purpose, Dawan Wang not only refused, but also killed the emissary and took away his property.

Emperor Wu of the Han Dynasty flew into a rage after hearing this, and sent Li Guangli, the general of the Second Division, to the Western Region Dawan State. However, due to ignoring the distance of the road, the invasion did not work and gave up halfway. Emperor Wu of Han Dynasty decided to send troops again in the third year of Han Dynasty. This time, the Han army was fully prepared. In addition to the last army, it also sent 60,000 troops, 65,438+10,000 cows, 20,000 batches of war horses and tens of thousands of camels, and only enough hay and arrows. As can be seen from the troops sent this time, there is no suspense about the outcome of the war between Korea and Wan, and Dawan is unstoppable.

After Li Guangli arrived at Dayuan, he surrounded Dayuan, cut off its water source, and captured Dayuan's war generals when he attacked Dayuan's outer city, which made Dayuan people panic. The nobles of Dawanguo were afraid of breaking the city, secretly murdering the king, and donating blood to make peace with the Han Dynasty. Finally, Li Guangli was named King of Dawan, and the war between Korea and Wan ended. The result of the war between Korea and Wan was entirely the fault of King Wan. It turns out that Liang Wudi sincerely sent messengers to buy blood horses. King Dawan didn't want to lose the BMW, so he refused. He also brutally killed the messengers and plundered their property, which led to his destruction by the powerful Han Dynasty.
