La Vérendrye became first commandant of the Posts of the West. He was posted to Fort Kaministiquia in this year and began the western expansion in 1731.
Natchez attacked French Fort Rosalie and French settlements nearby after the French commander of the fort, Sieur Chepart, ordered them to abandon their village of White Apple. The Natchez wiped out the entire settlement and captured Fort Rosalie. In 1730 and 1731 the French, aided by the Choctaw, launched two counterattacks out of New Orleans, capturing and selling into plantation slavery most of the tribe and its smaller allies. A few bands found refuge among the Chickasaw, Creek, and Cherokee.
