The French maintained the post throughout this time mostly due to its strategic significance along the Mississippi River. The post was moved back further from the Mississippi River in 1749 after the English with their Chickasaw allies attacked, it was moved downriver in 1756 to be closer to a Qua-paw defensive line that had been established, and to serve, as an repent, or trading post, during the Seven Years' War and prevent attacks from the Spanish along the Mississippi. After the war ended, the post was again moved upriver out of the floodplain in 1779.
