Jiucheng Palace raid
By summer 639, as Ashina Jiesheshuai had not been favored by the Tang Dynasty's Emperor Taizong (because he had falsely accused his brother Ashina Shibobi of treason, which Emperor Taizong found despicable), he formed a conspiracy with Ashina Shibobi's son Ashina Hexiangu (Chinese: 阿史那賀暹鶻) to assassinate Emperor Taizong at his summer palace, Jiucheng Palace (九成宮, in modern Linyou County, Shaanxi). They had planned to wait for Li Zhi the Prince of Jin to depart from the palace in the morning and use that opportunity to attack the palace. On the day they planned, May 19, however, Li Zhi did not leave the palace due to a storm and immediately afterwards heavy rainfall. Ashina Jiesheshuai attacked the palace anyway, engaging the palace guards, but the guards was supported by troops who came outside. Ashina Jiesheshuai and his comrades stole some 20 horses from the stable. They fled to the north, but were caught by pursuers near the Wei River and killed. Ashina Hexiangu was exiled to Lingbiao.
