"After the war, in 1792, he was appointed Major-General of the State militia, which office he held for thirty years. In 1799, when a war with France was anticipated, he received from President Adams the appointment of Brigadier-General in the U. S. army. He served also in the war of 1812. In 1810, and in 1817, he was elected a member of Congress. He died in 1834. Mrs. Sigourney describes him as having 'a fine figure,with military carriage, and a countenance, which was considered a model of manly beauty.' She speaks of the 'elegant manners,' and 'decision of character,' which 'were conspicuous in him, and unimpaired by age.'" [Source]
