Members of the company followed Newport native Commodore
Oliver Hazard Perry to
Put-in-Bay, Ohio and fought at the
Battle of Lake Erie in September 1813. In 1814, during the
War of 1812, the company was activated and garrisoned
Fort Greene in the
Point section of Newport. The company was inactivated when the
Treaty of Ghent, which ended the war, was signed in early 1815. In 1834, a plot of land was donated to the company by
Audley Clarke to build an armory. During the
Dorr War of 1842 to 1843, the company was one of several militia units to mobilize to suppress the rebellion against the government of Rhode Island. The Artillery Company of Newport volunteered to lead the charge against the Dorr defenses, because of this the unit has the right of line in any parade in Rhode Island to this day. During the American Civil War, the company was mustered into Federal service as Company F of the
1st Rhode Island Infantry (a.k.a. 1st Rhode Island Detached Militia) in April 1861 under the command of Captain (later Brevet Brigadier General) George W. Tew. It fought at the
Battle of Bull Run in July and was mustered out of Federal service in August. Individual members of Company F volunteered for service with other regiments after they were mustered out of service in August 1861. Members of the Company who were unable to serve in Company F were designated as the "Old Guard" and garrisoned
Fort Adams guarding the entrance to Newport Harbor from April to May 1861 when the fort became the site of the
United States Naval Academy which moved to Newport for fear the Confederates would invade Maryland. In 1862 the company was activated to provide the guard force at the newly established Lovell General Hospital at Portsmouth Grove, a few miles north of Newport. During the
Spanish–American War in 1898 the company was activated for one week and received training on coast defense guns at
Fort Adams so the company could supplement the fort's garrison in the event Newport was attacked. A number of members of the Company enlisted in the
1st Rhode Island Volunteer Infantry Regiment which served stateside from 1898 to 1899. ==Early 20th Century==
