Sentence subject clarity

Is it clear that the "trio's cause" refers to Raistlin and his companions?

After defeating Steeltoe in single combat, Caramon rallied the brigands to the trio’s cause and began the formation of the army of Fistandantilus, whose mission was to march on Thorbardin and raid the dwarven kingdom for its riches._
