The Coffeyville raid occurred on October 5, 1892, when the Dalton Gang, a group of outlaws, attempted to rob two banks in Coffeyville, Kansas. The gang, consisting of eight members, aimed to steal money and valuables but was met with resistance from local citizens and law enforcement. The robbery quickly turned into a violent confrontation. During the shootout, four members of the Dalton Gang were killed, along with several townspeople. The failed raid marked a significant moment in the history of the American West, highlighting the dangers of outlaw gangs and the determination of communities to defend themselves.
