Their commander was a man tall and strong in person, and rough in feature. He was versed in all the arts of woodcraft, sagacious, prompt, and resolute, yet so cautious withal that he sometimes incurred the unjust charge of cowardice. His mind, naturally active, was by no means uncultivated; and his books and unpublished letters bear witness that his style as a writer was not contemptible. But his vain, restless, and grasping spirit, and more than doubtful honesty, proved the ruin of an enviable reputation. Six years after the expedition of which I am about to speak, he was tried by a court-martial for a meditated act of treason, the surrender of Fort Michillimackinac into the hands of the Spaniards, who were at that time masters of Upper Louisiana.[147] Not long after, if we may trust his own account, he passed over to the Barbary States, entered the service of the Dey of Algiers, and fought two battles under his banners. At the opening of the war of independence, he returned to his native country, where he made professions of patriotism, but was strongly suspected by many, including Washington himself, of acting the part of a spy. In fact, he soon openly espoused the British cause, and received a colonel’s commission from the crown. His services, however, proved of little consequence. In 1778, he was proscribed and banished, under the act of New Hampshire, and the remainder of his life was passed in such obscurity that it is difficult to determine when and where he died.[148]
