About the same time he published anonymously two pamphlets in reply to publications emanating from the ministerial party, and in vindication of the measures of the American Congress. The powerful and eloquent manner in which the topics in controversy were discussed, excited great attention. The authorship of the pamphlets was attributed by some to Governor Livingston and by others to John Jay, and these contributed to give to those gentlemen, already distinguished, an increased celebrity; and when it was ascertained that the youthful Hamilton was the author of them, the public could scarcely credit the fact. Upon the actual breaking out of hostilities, Hamilton immediately applied himself to the study of military science, and obtained from the State of New-York a commission as captain of a company of artillery. His conduct at once attracted the observing eye of Washington, who soon invited him to become one of his staff with the commission of Lieutenant Colonel. Hamilton accepted the offer, and for the space of four years remained in the family of Washington, enjoying his unlimited confidence, carrying on a large portion of his correspondence, and aiding him in the conduct of the most important affairs. A hasty word from the latter led to a rupture of this connection, and Hamilton left the staff and resumed his place as an officer in the line; but Washington's confidence in him was not in the least impaired, and their friendship continued warm and sincere until the death of the latter. In thus separating himself from the family of the Commander-in-Chief, Hamilton was influenced by other motives than displeasure at the conduct of Washington. He knew that great man too well, and loved him too well, to allow a hasty word of rebuke to break up an attachment which had begun at the breaking out of the war, and which a familiar intercourse of four years, an ardent love of the cause, and a devotion to it common to them both had deepened and confirmed. But the duties of a secretary and adviser, important as they then were, were not adequate to call forth all his various powers, and the performance of them, however skilful, was not sufficient to satisfy that love of glory which he so fondly cherished. He was born to act in whatever situation he might be placed a first rate part. He longed to distinguish himself in the battles as well as in the councils of the war. He felt that his country had need of his arm as well as of his pen; and thus the dictates of patriotism, which he never in the course of his life allowed to stand separate from the promptings of his high ambition, pointed out to him the course he took. He would not, of his own motion, leave the immediate services of Washington; but when the opportunity was presented by the latter, he at once embraced it, and would not be persuaded by any considerations to return to his former place.
