晋献公
In 658 BC, the 19th year of his reign, Duke Xian of Jin sent his general Li Ke (里克) and his officer Xun Xi to attack the State of Guo during the reign of Duke Chou of Guo (虢公醜). Ever more favorable to Jin, the Duke of Yu assisted in the invasion. He sent his own army to capture Xiayang Pass (下陽關) for Jin, under the ruse that his army was there to subdue the rebellious Quanrong tribe.
