But Lord Dunmore's army was not destined to strike the decisive blow in the contest. The great Shawnee chief, Cornstalk, was as wary and able as he was brave. He had from the first opposed the war with the whites;[6] but as he had been unable to prevent it, he was now bent on bringing it to a successful issue. He was greatly outnumbered; but he had at his command over a thousand painted and plumed warriors, the pick of the young men of the western tribes, the most daring braves to be found between the Ohio and the Great Lakes. His foes were divided, and he determined to strike first at the one who would least suspect a blow, but whose ruin, nevertheless, would involve that of the other. If Lewis' army could be surprised and overwhelmed, the fate of Lord Dunmore's would be merely a question of days. So without delay, Cornstalk, crafty in council, mighty in battle, and swift to carry out what he had planned, led his long files of warriors, with noiseless speed, through leagues of trackless woodland to the banks of the Ohio. The backwoodsmen who were to form the army of Lewis had begun to gather at the Levels of Greenbriar before the 1st of September, and by the 7th most of them were assembled. Altogether the force under Lewis consisted of four commands, as follows: a body of Augusta troops, under Col. Charles Lewis, a brother of the general's;[7] a body of Botetourt troops, under Col. William Fleming;[8] a small independent company, under Col. John Field; and finally the Fincastle men, from the Holston, Clinch, Watauga, and New River[9] settlements, under Col. William Christian.[10] One of Christian's captains was a stout old Marylander, of Welsh blood, named Evan Shelby; and Shelby's son Isaac,[11] a stalwart, stern-visaged young man, who afterwards played a very prominent part on the border, was a subaltern in his company, in which Robertson likewise served as a sergeant. Although without experience of drill, it may be doubted if a braver or physically finer set of men were ever got together on this continent.[12] Among such undisciplined troops it was inevitable that there should be both delay and insubordination. Nevertheless they behaved a good deal better than their commander had expected; and he was much pleased with their cheerfulness and their eagerness for action. The Fincastle men, being from the remote settlements, were unable to get together in time to start with the others; and Col. Field grew jealous of his commander and decided to march his little company alone. The Indians were hovering around the camp, and occasionally shot at and wounded stragglers, or attempted to drive off the pack-horses. The army started in three divisions. The bulk, consisting of Augusta men, under Col. Charles Lewis, marched on September 8th, closely followed by the Botetourt troops under Andrew Lewis himself.[13]
