Wyoming in July--Cherry Valley in November, were only on a larger scale the repetition of recurring events along the entire frontier. The blood-curdling yell, accompanied by the tomahawk and scalping knife, were a constant menace to the settler. The demand for decided measures was imperative. The Wyoming massacre sent a thrill of horror through the country, and renewed the demand for retaliatory measures. General Washington was directed to take such measures as he deemed advisable, for the protection of the frontiers. Realizing the country's condition and the great need of economy in public expenditures, Washington's policy for 1779 was to remain on the defensive, except as might be found necessary to hold the Indians in check. England's affairs in Europe at this time were such that she would not be apt to push her operations in America. Washington himself was an experienced Indian fighter--knew how they could be punished--early favored an expedition into the heart of the Indian country--having but little faith in the plan of establishing forts. He wished to carry the war to their own homes, destroy villages and crops and compel them to accept peace or depend on the British for sustenance. The country to be traversed on such an expedition was but little known, so Washington during the winter and spring devoted a great deal of time to obtaining information needed and planning for the campaign, which was subsequently shown to be the most important event of that year, and furnished a lasting lesson to the hostile tribes of the North. After the declination of the command by General Gates, Washington tendered the command, which was promptly accepted by General Sullivan, whose patriotism and bravery were well known. Preparations were immediately commenced for the great undertaking. Hamilton under Washington's direction, drew up a letter of instructions, which was signed by Washington. The first paragraph is interesting: "May 31, 1779. Sir:--The expedition you are appointed to command is to be directed against the hostile tribes of the Six Nations of Indians with their associates and adherents. The immediate object is their total destruction and devastation and the capture of as many persons of every age and sex as possible. It will be essential to ruin their crops, now on the ground, and prevent their planting more." Then followed instructions more in detail, showing that Washington had acquired an almost accurate knowledge of the country not only, but the people as well. His instructions were carried out almost to the letter as far as the army proceeded. Sullivan concluded when he had driven them from the valley of the Genesee that his mission was fulfilled.
