The French, along with their Choctaw allies, besieged the Natchez in forts built near the site of the Grand Village of the Natchez, a mile or so east of Fort Rosalie. In late February 1730, the Natchez left the two forts and escaped across the Mississippi River. Throughout the 1730s the French organized expeditions to attack the Natchez, who had taken refuge among the Chickasaws.
