Saint Denis Mob

The Saint Denis Mob is an Italian criminal organization based in Saint Denis, Bayou Nwa, with influence across Lemoyne. Angelo Bronte leads it before his death in 1899, using bribery, fraud, smuggling and racketeering to build his power. Its payments protect it from the Saint Denis Police Department, while guards and other men work from Bronte's mansion on Flavian Street. The group also has ties to the Braithwaite family.

During the gang's time at Horseshoe Overlook, a newspaper reports that mob members shoot police officer Henry Jenkins after he investigates Bronte. Later, the Braithwaites abduct Jack Marston and hand him to Bronte. In Saint Denis, Dutch van der Linde, Arthur Morgan and John Marston go to Bronte's mansion, where his armed guards admit them at gunpoint. Bronte agrees to release Jack if Arthur and John deal with grave robbers who have stolen without paying him. Jack returns to the Van der Linde gang after they do so.

Bronte later receives Dutch and Arthur at Mayor Henri Lemieux's party, where Luca Napoli welcomes them and Guido Martelli joins Bronte and his men. Bronte tells Dutch about cash supposedly left unguarded at a trolley station. The robbery is a trap, and Dutch leads Arthur, John, Bill and Lenny back to Bronte's property. They fight through the guards, find Bronte in his bath and take him away despite police arriving to rescue him. On a boat, Dutch drowns Bronte and throws his body to an alligator.

The remaining mobsters become hostile toward Arthur after Bronte's death, and their men continue to appear around Saint Denis. By 1907, Guido Martelli commands the organization. Charles Smith angers Martelli's men after winning a street fight he had agreed to lose for their bet. John joins Charles when four mobsters confront him in Saint Denis. They kill the attackers in a short gunfight and escape the city.
