Carib people
Poincy continued to develop the colonies. He built strong and impressive fortifications on Saint Christopher along with churches, roads, a hospital, and his own grand residence, the Château de la Montagne. Outside the capital, Hospitaller rule was more precarious. The settlement on Saint Barthélemy suffered an attack by Carib people, and those who were not killed abandoned the island. Poincy sent a group of 30 men to replace them, which grew to 100 by 1664. In 1657 a rebellion overthrew the Hospitaller regime on St. Croix. Poincy sent a new governor to restore order, build fortifications and a monastery, and begin to clear much of the island's forests for plantation agriculture.
