Campbell's ascension to the lead Regulator post was met with hostility from the Driscoll camp. William Driscoll immediately sent Campbell a letter offering to kill him. Campbell responded in kind; he assembled 200 Regulators, and marched to the Driscoll home. A small group of Banditti had gathered at the Driscoll homestead, but seeing they were outnumbered, they fled, only to return with the DeKalb County sheriff and other authorities in tow. The sheriff and his companions did not see the events as the outlaws had hoped; they sided with the vigilantes, and the Driscolls promised to leave within twenty20 days. Instead of leaving, the Driscolls and the other Banditti held a meeting in which they determined that Campbell and his fellow Regulator, Phineas Chaney, had to be murdered.
