More brief conflicts between these two countries along the coastline followed. Spanish priests established missions intending to convert Native Americans to Christianity. No mission is known to have been established on Jekyll; however, the Spanish influenced the island from their mission on St. Simons Island. After the Westo invasion on the mainland, they began destroying the missions and slaying the Spanish priests, traveling south along the coast. They spared Father Xander Davilla on Jekyll, keeping him as a slave. (He was later released to the Spanish in a prisoner exchange).
