Ma Dai

Biography & Historical Record of Ma Dai

Ma Dai (active 211–234 AD) was a military general of the state of Shu Han during the Three Kingdoms period. He was a nephew of the northwestern warlord Ma Teng and a younger cousin of Ma Chao. Following the execution of Ma Teng and his family by Cao Cao, Ma Dai accompanied Ma Chao during his vengeful campaign at Tong Gate and subsequent resistance against Cao Wei. After Ma Chao’s defeat and temporary refuge under Zhang Lu in Hanzhong, Ma Dai fled alongside his cousin and defected to Liu Bei when Ma Chao swore allegiance to Shu Han.

In Shu Han, Ma Dai served faithfully as a reliable cavalry commander under Liu Bei and later became one of Zhuge Liang’s most trusted generals during the Northern Expeditions. Possessing steady loyalty and tactical competence, Ma Dai participated in multiple campaigns against Cao Wei. His most famous historical and literary moment occurred in 234 AD at Wuzhang Plains following Zhuge Liang’s death. Anticipating potential treason, Zhuge Liang left a secret instruction to Ma Dai and Yang Yi. When the rebellious general Wei Yan shouted defiantly, “Who dares to kill me?!” (“Shei gan sha wo?!”), Ma Dai executed his famous surprise ambush from behind, shouting, “I dare!” (“Wo gan!”), decapitating Wei Yan on the spot and saving Shu Han from civil war. For this decisive deed, Ma Dai was promoted to Senior General of Chariots and Cavalry and created Marquis of Cengxi.

Role in Romance of the Three Kingdoms

In Luo Guanzhong’s epic historical novel Romance of the Three Kingdoms, Ma Dai is portrayed as a loyal, dependable, and sharp-witted commander who stands as Ma Chao’s faithful shadow and protector. From escaping the purges of Chang’an to participating in Zhuge Liang’s brilliant stratagems during the Northern Expeditions, Ma Dai’s narrative peaks in Chapter 105, where his heroic ambush and execution of the traitor Wei Yan fulfills Zhuge Liang’s ingenious posthumous plan.
