The governor of Louisiana and founder of New Orleans, Jean-Baptiste Le Moyne de Bienville determined to stop Chickasaw trade with the British. In 1721 he was able to incite the Choctaw who began to raid Chickasaw villages, and to ambush pack trains along the Trader's Path leading to Charleston, South Carolina. In response, the Chickasaw regrouped their villages more tightly for defense, and cemented relations with their British source of guns by establishing a settlement at Savannah Town, South Carolina, in 1723. They blocked French traffic on the Mississippi River by occupying Chickasaw Bluff near present day Memphis, and bargained for peace with the Choctaw. Bienville himself was recalled to France in 1724 . On and off over the following years, the French successfully reignited the Indian conflict. The Choctaw pursued their familiar hit and run tactics: ambushing hunting parties, killing trader's horses, devastating croplands after using superior numbers to drive the Chickasaw into their forts, and killing peace emissaries. Illini and Iroquois occasionally pitched in from the north as well. This war of attrition effectively wore the Chickasaw down, reaching a crisis level in the late 1730s and especially the early 1740s. After a lapse due to strife within the Choctaw, the bloody harassment resumed in the 1750s. The Chickasaw remained obstinate, their situation forcing them to adhere even more closely to the British. In 1734, Bienville returned to Louisiana, and waged grand campaigns against the Chickasaw in the European style.
