In Chinese military history, there was a classic battle named 虎牢之战—the Battle of Hulao.
It was in the third year of the Emperor Tang Wude武德’s reign (618—626). The emperor was still new and the Central Government was not very strong. There were frequent uprisings. Li Shimin李世民, King of the Qin State (who later became the second emperor of the Tang Dynasty) directed his army to attack the rebels in the City of Luoyang洛阳. But Luoyang’s fortifications were very strong. Li’s soldiers were not able to get into the city. So he put the city under siege so that the enemy’s food and supplies would be cut off.
In the meantime, another uprising had taken place in the city of Hulao. The rebels there intended to storm in and rescue Luoyang. King Li decided to leave a small portion of his army in Luoyang to continue the siege and take the rest of his soldiers to fight the rescue troops in Hulao. After a few months of stalemate, Li Shimin devised a trick to lure the relief troops from the city of Hulao. His trick worked, and he destroyed them. Soon, the starving enemy in Luoyang also surrendered.
The Battle of Hulao is heroic story of the 24-year-old. Li Shimin defeating two sets of rebels with one battle. He is remembered for his strategy of besiege the left and attacking the right.
