The Newburg Gang is a small gang of hired bandits headed by Barrett Newburg, and whose members have included Landon Wylam and Leo Rukavina. They have no notable history per se; they are just a bunch of ruffians with weak morals and a strong affinity for money.
Fair Play was once terrorized by the Newburg Gang ( Foul Play in Fair Play – part 1), causing the stage line to temporarily divert to Grunting Hollow. A group of marshals (who were stranded in the town by the incident) were able to apprehend the culprits ( Foul Play in Fair Play – part 2) and traveled to Grunting Hollow to deal with their employer (Jerome Hunt) at the source ( Hollow Threats – part 1 and part 2). The Newburg Gang (as well as Sal Early’s highwaymen and several hired henchmen from Grunting Hollow) were eventually transported to River Junction for trial and incarceration ( Take Me To The River – part 1).
