While heading towards the location, Sima Yi's subordinates suggested that they observe Meng Da's actions first before advancing, but Sima Yi replied: "(Meng) Da is not a trustworthy person. Now that he is hesitating due to suspicions, we should seize this opportunity to get rid of him." The marching speed was subsequently hastened and, covering 2,200 "li", Sima Yi reached there within eight days and ordered his subordinates to lead separate detachments to intercept and block Meng Da's reinforcements in the form of Shu and Wu forces that had just arrived at Anqiao () and Mulan Fort () in Xicheng () respectively.
