In 1861, Jewett joined the New York National Guard as a private in Company C of the Seventy-fourth Regiment, under the leadership of William Findlay Rogers.

The last position he achieved as a member of the New York National Guard was that of brigadier general of the 8th Brigade, on March 29, 1884.

On March 1, 1894, Mayor Charles F. Bishop appointed Jewett to the Board of Police Commissioners for a term of five years.
