"DEAR SIR,--In a conversation at Green Spring you gave me some room to hope for a commission above that of a Major, and to be ranked among the chief officers of this expedition. The command of the whole forces is what I neither look for, expect, or desire; for I must be impartial enough to confess, it is a charge too great for my youth and inexperience to be intrusted with. Knowing this, I have too sincere a love for my country, to undertake that which may tend to the prejudice of it. But if I could entertain hopes that you thought me worthy of the post of Lieutenant-colonel, and would favour me so far as to mention it at the appointment of officers, I could not but entertain a true sense of the kindness. "I flatter myself that under a skilful commander, or man of sense, (which I most sincerely wish to serve under,) with my own application and diligent study of my duty, I shall be able to conduct my steps without censure, and in time, render myself worthy of the promotion that I shall be favoured with now." The commission he solicited was transmitted to him by Mr. Corbin, in the following laconic letter: "DEAR GEORGE,--I inclose you your commission. God prosper you with it. "Your friend, RICHARD CORBIN."] While the regiment was on its march to join the detachment advanced in front, the command devolved on Lieutenant Colonel Washington by the death of Colonel Fry. Soon after its arrival, it was reinforced by two independent companies of regulars. After erecting a small stockade at the Great Meadows, Colonel Washington commenced his march towards fort Du Quesne, with the intention of dislodging the French from that place. He had proceeded about thirteen miles, when he was met by some friendly Indians, who informed him that the French and their savage allies, "as numerous as the pigeons in the woods," were advancing rapidly to meet him. Among those who brought this information was a trusty chief, only two days from the fort on the Ohio, who had observed the arrival of a considerable reinforcement at that place, and had heard their intention of marching immediately to attack the English, with a corps composed of eight hundred French and four hundred Indians. This intelligence was corroborated by information previously received from deserters, who had reported that a reinforcement was expected. The troops commanded by Colonel Washington were almost destitute of provisions; and the ground he occupied was not adapted to military purposes. A road at some distance, leading through other defiles in the mountains, would enable the French to pass into his rear, intercept his supplies, and starve him into a surrender, or fight him with a superiority of three to one. {June 23.}
