The Battle of Mount Qi (祁山の戦い, rōmaji: Kizan no Tatakai) refers to the series of conflicts surrounding the mountain, a strategic point during Zhuge Liang's Northern Campaigns against Wei. When Zhuge Liang first tried to take the mountain, he ordered Ma Su to lead the expedition that resulted in the defeat at Jieting. Two years later, Zhuge Liang then led the Shu army personally to claim the mountain. Although the accounts and details of the battle vary, the conflict ultimately resulted in Zhang He's death.
