The Italian Mafia

As the Allies began their advance into Sicily and, eventually Southern Italy, did the Mafia play a role? Such as reconnaissance, scouting, demolition, fighting alongside the Allies, etc. Also, how did the civilians population of Sicily react to the Allies. Were they in gleeful mood or neutral? I hope this can be answered. To the team who makes these videos, I wish the best for all. Godspeed.
