Hostilities resumed in 1763 with Pontiac's War, when Shawnee attacks forced colonists to abandon frontier settlements along the Jackson River, as well as the Greenbrier River now in West Virginia, the associated valleys on either side of the Allegheny ridge, and the latter just beyond the Treaty of Easton limit. Meanwhile, the Crown's Proclamation of 1763 confirmed all land beyond the Alleghenies as Indian Territory. It attempted to set up a reserve recognizing native control of this area and excluding European colonists. Shawnee attacks as far east as Shenandoah County continued for the duration of Pontiac's War, until 1766.
