The alliance between the Cherokee and the British began to unravel with the British expedition under General Forbes against Fort Dusquesne in 1758. The Cherokee felt their efforts were unappreciated. Conocotocko, then the leading chief of the Cherokee, ordered his warriors home. Later, a contingent of Cherokee warriors under Moytoy accompanied Virginian troops on a campaign against the Shawnee of the Ohio Country. During the expedition, the enemy proved elusive. After several weeks, the Tuscarora contingent left, while that of the Cherokee stayed, but dwindled. Then, a group of Cherokee warriors scalped and killed one or more white settlers and deceptively attempted to proclaim to the British the scalps belonged to their enemies in order to receive a reward. Suspicious of the truth, the British soldiers disarmed and briefly detained them, and then chose to send them home. Some Cherokees, who had not been involved in the treachery, were bitter over this treatment, and raided Virginia's frontier settlements while returning to the Tennessee Valley. Virginia settlers got angry and banded together to pursue the Cherokee, attacking them and killing, scalping and mutilating 20 of the Indians, later collecting the bounty offered for enemy scalps. Although Dinwiddie, the lieutenant governor of Virginia, apologized other Virginians called them horse thieves. Some Cherokees retaliated and the situation spun out of control.
