Wèi sent Zhūgě Dàn, Hú Zūn and others to attack Dōngxīng, Zhūgě Kè led the army to resist them. The various officers all said: “The enemy hears the Grand Tutor has personally come, and when we ascend shore they will certainly evade and flee.”
Fèng alone said: “Not so. They have moved within their borders, with all of Xǔ and Luò’s troops greatly raised and come, they certainly have established course, how can they with nothing return? Do not depend on the enemy not coming, depend on us being able to surpass them.”
When [Zhūgě] Kè ascended shore, Fèng with Generals Táng Zī, Lǚ Jù, Liú Zàn and others, together from the mountains went west upstream. Fèng said: “Now the various armies travel slowly, if the enemy occupies convenient territory, then it will be difficult to with them contend it.” Therefore he led the various armies to take the downstream road, leading his banner men of 3000 men to directly advance.

The weather was cold and snowing, the enemy’s various officers set liquor and had high meetings, Fèng observed their front division’s troops were few, and said: “Obtaining fief and reward, is on this day!” Therefore he sent troops to take off armor and [only] wear helmet, and wield short weapons. The enemy from this only laughed, and did not make preparations. Fèng released troops to hew them, greatly defeating the enemy’s front camp. It happened that [Lǚ] Jù and the rest arrived, and the Wèi army therefore dispersed. He was promoted to Exterminating Bandits General, advanced in fief to a capital village Marquis.

Sūn Xiū  ascended the throne, and with Zhāng Bù plotted, wishing to execute Sūn Chēn, [Zhāng] Bù said: “Although Dīng Fèng cannot be an official for documents, yet his planning and strategy surpasses others, and he can settle great affairs.”
[Sūn] Xiū summoned Fèng and informed him: “[Sūn] Chēn seizes the state’s authority, and will be without course, and I wish to with you General punish him.”
Fèng said: “The Chancellor [Sūn Chēn] and his brothers and friends and associates extremely flourish, and one fears people’s hearts are not the same, and cannot in the end be controlled. We can therefore at the [twelfth moon] meeting, have Your Majesty’s troops punish him.” [Sūn] Xiū accepted this plan, and therefore had meeting inviting [Sūn] Chēn, and Fèng with Zhāng Bù looked to have attendants behead him. He was promoted to General-in-chief, and also Left and Right Capital Protector.

He was promoted to Right Marshal-in-Chief and Left Master of the Army. Bǎodǐng Third Year , [Sūn] Hào ordered Fèng with Zhūgě Jìng to attack Héféi. Fèng with Jìn Chief General Shí Bāo had letter, explaining things to him, and [Shí] Bāo from this was summoned back. Jiànhéng Inaugural Year , Fèng again led armies to repair Xútáng, and therefore attacked Jìn’s Gǔyáng. Gǔyáng’s people knew him, and all left, and Fèng captured none. [Sūn] Hào was angry, and beheaded Fèng’s Military Guide. Third Year , he died.
