On November 22, 1863, the A.J. Oliver stage was robbed on its way to Bannack from Virginia City by road agents George Ives, "Whiskey Bill" Graves and Bob Zachary. The robbery netted less than $1000 in gold and treasury notes. One of the victims, Leroy Southmayd made the mistake of reporting the robbery and identifying the road agents to Bannack Sheriff, Henry Plummer. Members of Plummer's gang confronted Southmayd on his return trip to Virginia City, but Southmayd was cunning enough to avoid injury or death. - Wikipedia.
