They had been the staunchest Indian supporters of the new British colony, and had sent 28 men of auxiliary troops to Colonel Barnwell, to defeat the Tuscarora insurrection on the coast of North Carolina (1712-13), when they suddenly revolted on April 15th, 1715, committed the most atrocious deeds against helpless colonists, and showed themselves to be quite the reverse of what their name indicates (yámasi, yámassi, the Creek term for _mild, gentle, peaceable_[44]). Among their confederates in the unprovoked insurrection were Kataba, Cheroki and Congari Indians. Wholesale massacres of colonists occurred around Pocotaligo, on Port Royal Island and at Stono, and the number of victims was estimated at four hundred. A force of volunteers, commanded by Governor Craven, defeated them at Saltketchers, on Upper Combahee river, southern branch, and drove them over Savannah river, but for a while they continued their depredations from their places of refuge (Hewat, Histor. Acc., I, 213-222).
