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.
