Before the start of the 1991 season, Adolph DeGrauwe stepped down as Corps director, and was replaced by Jeff Fiedler. 1991 was a very good year for The Cavaliers, even though the corps still could not win DCI. In eight meeting with Star of Indiana prior to DCI in Dallas, Star had won seven times. There had also been loses to Phantom and BD, but mostly, The Cavaliers were winners. At DCI East in Allentown, Pennsylvania, the rains came as the Cavaliers were performing, this seemed to bring out the corps' best and they won the DCI East title. They also won DCI South on an oppressively hot day in Birmingham. At Dallas, the percussion ensemble won the Individual and Ensemble contest with a perfect 100.00 score, and The Cavaliers were far ahead of all others, except Star and the "Christmas Show" earned the corps' second consecutive second-place finish. 1992 started with a fire in the equipment truck, but the corps was also on fire and won their first fifteen shows before falling to Phantom. Star won the DCM Championships in Toledo after Cavaliers had been consistently beating them. The Cavaliers won DCI North in Buffalo, but at the Preview of Champions in Nashville, the corps found themselves trailing not only Star, but also BD. The Green Machine then returned to winning until losing back-to-back Regionals; to Star at DCI Mid-America in Bloomington, Indiana and to Blue Devils at DCI North in Ypsilanti, Michigan. At the DCI World Championship Quarterfinals in Madison, the Cavaliers were second to the defending champion, Star of Indiana, but at Semifinals, The Cavaliers moved into the lead. At Finals, The Cavaliers' show title of "Revolution and Triumph" proved to be prophetic, as the corps was finally crowned DCI World Champions.
