On Sunday, May 14, Mother's Day, in Anniston, Alabama, a mob of Klansmen, some still in church attire, attacked the first of the two Greyhound buses. The driver tried to leave the station, but was blocked until KKK members slashed its tires. The mob forced the crippled bus to stop several miles outside of town and then threw a firebomb into it. As the bus burned, the mob held the doors shut, intending to burn the riders to death. Sources disagree, but either an exploding fuel tank or an undercover state investigator brandishing a revolver caused the mob to retreat, and the riders escaped the bus.
