Liu Heita
Finally, when he judged the situation ripe, Li Shimin feigned detaching part of his forces north to entice an attack. When Dou took the bait and advanced to the Tang positions in battle order, Li Shimin held back his own troops for several hours, until the troops of Dou Jiande were exhausted from being made to wait in formation under the sun for the entire morning. Once signs of disorder began appearing among them, Li Shimin attacked, breaking the opposing army and capturing Dou Jiande. Subsequently, Wang Shichong, left with no other choice, surrendered Luoyang. Both his and Dou Jiande's states were absorbed by the Tang. Dou Jiande was later executed, resulting in some of his followers, led by Liu Heita, raising an unsuccessful rebellion against the Tang. Hulao marked the decisive turning point in the civil wars that followed the collapse of the Sui Dynasty, after which the eventual victory of the Tang was never in doubt.
