The gang's primary activities included bootlegging and hijacking of trucks and alcohol shipments.
The gang was founded by Ralph Sheldon in the months following the passage of the Volstead Act and it quickly became one of major liquor suppliers in Chicago's Southwest Side as well as a main supplier to Al Capone.
In October, a general amnesty had been ordered between Al Capone's Chicago Outfit and Bugs Moran's North Side Gang.
Joe Saltis soon went to Capone who, in exchange for a large percentage of his profits, would negotiate peace between the two.
Sometime in the 1930s, the Sheldons dropped a bomb from an airplane into an ice cream store, in Creve Coeur, Illinois.
