 Turnbull's settlers eventually succeeded in producing crops of high quality indigo, hemp and sugarcane for making rum, but the plantation suffered major losses due to insect-borne diseases and Native American raids.Meanwhile, tensions grew between Turnbull and the colonists because of his neglect and mistreatment by his overseers.The remaining colonists marched north in 1777 to St. Augustine along the King's Road to complain of this mistreatment to Governor Patrick Tonyn, and permanently abandoned New Smyrna when he offered them sanctuary.
