Yancey, like most members of the planter class, was a strong believer in a personal code of honor. In September 1838, Yancey returned for a brief return visit to Greenville. A political slur by Yancey in a private conversation was overheard by a teenage relative of the aggrieved party. Yancey was confronted by another relative (and his wife's uncle), Dr. Robinson Earle. Conversation turned to violence, and the always-armed Yancey ended up killing the doctor in a street brawl. Yancey was tried and sentenced to a year in jail for manslaughter. An unrepentant Yancey was pardoned after only a few months, but while incarcerated he wrote for his newspaper, "Reared with the spirit of a man in my bosom—and taught to preserve inviolate my honor—my character, and my person, I have acted as such a spirit dictated."
