After the British imposed the Proclamation Line of 1763 to prohibit colonial settlement west of the Appalachian Mountains, some settlers continued moving westward without recognizing British authority. Virginia Governor Lord Dunmore, concluding that peace with Native Americans was unlikely, gathered troops and moved west to the Hocking River to join a unit commanded by Andrew Lewis. Before they met, Lewis's troops were attacked on October 10, 1774, at present-day Point Pleasant, West Virginia, by Delaware and Shawnee forces led by Cornstalk. After an intense battle, the Native Americans retreated north across the Ohio River to villages on the Pickaway Plains. Dunmore then advanced to the Shawnee villages to negotiate peace and camped at this site. The resulting Treaty of Camp Charlotte ended Dunmore's War, required the Indians to give up rights to land south of the Ohio River, allowed boats to travel on the river undisturbed, established the Ohio River as Virginia's boundary line, and aided the settlement of Kentucky.
