The war sort of began with the attempted assassination of Vic Orena in June 1991. But then there was a ceasefire and some sit downs with the other families. Finally the shooting really began in November 1991 with the attempted murder of Greg Scarpa. The fighting continued for two years and ended with the murder of underboss Joseph Scopo in October 1993. There were some sporadic ceasefires during that time, especially in 1993, but the murder of Scopo is what really led to the peace between the two.
