Ma Teng’s Assassination Plot Against Cao Cao

Ma Teng’s Assassination Plot Against Cao Cao is a failed conspiracy against Cao Cao, set in motion by a summons that Ma Teng recognizes may be a trap. The plot briefly links Ma Teng’s opposition to Cao Cao with Huang Kui’s resentment, but a private betrayal exposes it before the conspirators can act. Cao Cao converts their plan to lure him outside the city into an opportunity to ambush and execute them.

Summons and Suspicion

Cao Cao’s invitation to Ma Teng is presented as a request for help in attacking the south, but Cao Cao’s underlying purpose is to draw the western tribal leader to the capital and kill him, thereby removing the danger of an attack on his own territory. Ma Teng does not accept the offer at face value. He recognizes that it may be a trap and discusses the dilemma with his eldest son, Ma Chao.

Ma Teng explains that he had once been involved in an effort to bring about Cao Cao’s death: the Secret Imperial Edict conspiracy. That earlier plot failed, and the new summons places him in a difficult position. Because Cao Cao controls the emperor, refusing the summons could be treated as treason. Ma Chao advises his father to go, both to avoid that charge and to use the occasion as a chance to renew his effort against Cao Cao. The decision is therefore not simply a response to an invitation: it brings Ma Teng into the capital under the authority of a court Cao Cao controls, while leaving open the possibility of resistance.

A Conspiracy Takes Shape

Ma Teng travels to the capital accompanied by five thousand tribal warriors for protection. Cao Cao assigns Huang Kui to oversee his reception and comfort, but also instructs him to reduce the size of his own force, on the grounds that Cao Cao will provide troops and that provisions are limited. The arrangement places Ma Teng’s security partly in the hands of an official serving Cao Cao.

After drinking with Ma Teng, Huang Kui inadvertently reveals his hatred of Cao Cao for usurping imperial prerogatives. Ma Teng is initially cautious and does not immediately disclose his own hostility. Huang Kui then refers to the earlier plot involving the Secret Imperial Edict, convincing Ma Teng that his resentment is genuine. The two agree to assassinate Cao Cao: they will lure him out of the city to inspect the troops, where Ma Teng will kill him. The plan depends on using an inspection to bring Cao Cao within reach of Ma Teng.

Betrayal and Exposure

The conspiracy is compromised not through a direct confrontation between Cao Cao and the plotters, but through Huang Kui’s household. Disturbed after returning home that night, Huang Kui does not tell his wife about the plan. Instead, he confides in his concubine, Li Chunxiang. She is having an affair with her brother-in-law, Miao Ze, who wants her for himself. Li Chunxiang tells Miao Ze what she has heard; Miao Ze sees a way to remove Huang Kui and gain Li Chunxiang, and reports the plot to Cao Cao.

Cao Cao responds by summoning his commanders and preparing a counter-plot. The episode’s turn rests on an intimate disclosure becoming political intelligence: Huang Kui tells one person, that person passes the information to Miao Ze, and Miao Ze converts it into a means of serving his personal interest. The plot might have succeeded, the narrative observes, but the betrayal gives Cao Cao advance knowledge and lets him dictate the terms of the encounter.

Ambush and Aftermath

The next morning, Ma Teng, his sons, and their troops parade before the city walls. A group of banners comes out through the gate, and Ma Teng and his sons mistake it for Cao Cao’s position and charge. The banners part to reveal archers and crossbowmen, while Cao Cao’s men attack from multiple directions. One of Ma Teng’s sons dies defending him; Ma Teng and his other son are captured, both seriously wounded, and brought before Cao Cao along with Huang Kui.

Ma Teng and his son are condemned and executed. Miao Ze then approaches Cao Cao to ask for Li Chunxiang as his reward, exposing the self-interested motive behind his disclosure. The outcome closes the conspiracy through two forms of power: Cao Cao’s ability to arrange the armed ambush, and Miao Ze’s ability to turn private knowledge into advancement. Ma Teng’s earlier involvement in the Secret Imperial Edict conspiracy thus leads into a second attempt that is defeated before its central action—the planned inspection and assassination—can take place.
