British veterans of the Great War turn to organized crime in this history of rival street gangs and their reign of terror in the 1920's.

When the returning heroes of the First World War were forgotten by their country, they had no choice but to fight again, this time for their own survival. Reduced to motley neighborhood regiments, they traded their rifles for razors and butcher's knives. The enemy was society at large—and the police force paid to protect it.

Money would be made, blood would be shed, and lives would be lost. Sheffield was a city at war with itself, as opposing gangs battled daily for control of the streets. Out of these deadly gangs, two rival factions took control of the city. For a dark and dangerous time, The Mooney Gang and the Park Brigade even acted as governing bodies in many of the poorer neighborhoods. In Sheffield's Most Notorious Gangs, true crime historian Ben W. Johnson explores their rise to power, and the rising tide of violence that authorities seemed powerless to stop.
