Emperor Wudi responded by giving Li Guangli a much larger army along with a huge number of oxen, donkeys and camels to carry supplies. With this force he had no difficulty reaching Ershi, the Dayuan capital. After a 40-day siege the Chinese had broken through the outer wall and cut off the water supply. The nobles of Ershi killed their king and sent his head to Li Guangli, offering the Chinese all the horses they wanted. Li accepted the offer, appointed one of the nobles to be the new king and withdrew with the horses. On his return journey all the petty states accepted Chinese sovereignty. He reached the Jade Gate about 100 BC with 10,000 men and 1,000 horses.
