"In 1812 President James Madison offered him the post of Secretary of War, which he declined, and accepted the appointment of quartermaster-general of the armies of the United States. In 1813 General Lewis was promoted to the rank of major-general. He served on the Niagara frontier, captured Fort George, and commanded at Sackett's Harbor and French Creek. At the close of the war he advanced the funds that were necessary for the discharge of American prisoners in Canada."
He married into the Livingston family of New York.
