According to the Book of Jin, he was not told about the plan, hatched by his father and his older brother, until the last minute—a view disagreed with by other historians, who assert that he was intimately involved in the planning. Regardless, in the aftermath of the successful coup his father became the paramount political authority in Wei, and he himself received an addition of 1,000 households to his fief and became important in status. In 251, when his father suppressed the failed rebellion of Wang Ling, Sima Zhao served as deputy commander, and was rewarded with the addition of 300 households to his fief and a Marquis post for his young son, Sima You. During the next few years, he was involved in commanding forces in repelling invasions by Shu's commander of the armed forces, Jiang Wei. Battle of Dongxing
