Colonel Andrew Lewis, in command of about 1,000 men, was part of a planned two-pronged Virginian invasion of the Ohio Valley. As Lewis's force made its way down the Kanawha River, guided by pioneering hunter/trapper Matthew Arbuckle, Sr., Lewis anticipated linking up with another force commanded by Lord Dunmore, who was marching west from Fort Pitt, then known as Fort Dunmore. Dunmore's plan was to march into the Ohio Valley and force the indigenous inhabitants to accept Ohio River boundary which had been negotiated with the Iroquois in the 1768 Treaty of Fort Stanwix.
