When his eldest son Sima Shi urges him to write a memorial at once and report to the Son of Heaven, Sima Yi says that waiting for an imperial decree would take a month there and back and the matter would be too late; he immediately sets his men and horses on the march, making them cover two days' journey in one and ordering that any who lag behind be beheaded on the spot. At the same time he sends his Army Adviser Liang Ji with a dispatch to hurry through the night to Xincheng and tell Meng Da and the others to make ready to march out on campaign, so that Meng Da will not suspect anything; Liang Ji sets off first, and Sima Yi raises his troops and follows behind him.

At Xincheng, Meng Da has agreed with Shen Yi, Grand Administrator of Jincheng, and Shen Dan, Grand Administrator of Shangyong, on a date for rising, but the two have only pretended to consent and are waiting for the Wei army to arrive so that they can act as its inside force. Then it is reported that the Army Adviser Liang Ji has arrived, and Meng Da welcomes him into the city. Liang Ji delivers Sima Yi's order: Commander-in-Chief Sima, by the Son of Heaven's edict, is raising the troops of the various routes to drive back the Shu army, and the Grand Administrator is to assemble the troops of his own command and await instructions.

When Meng Da asks when the Commander-in-Chief is setting out, Liang Ji answers that by now he should have left Wancheng and be on his way to Chang'an.

Soon, however, Xu Huang's troops come racing up below the city walls and Sima Yi's army arrives from all sides, and Meng Da, going out of the city in the belief that a relief force has come, is speared from his horse by Shen Dan and beheaded.
