The 8-Inch Rifles at the University of Maine
Two US Navy 8-Inch (180-Pounder) Muzzle Loading Rifles have been displayed at the University of Maine in Orono since Llewellyn N. Edwards, Class of 1898, facilitated their donation by the Navy in 1932. The cannons, originally cast as 11-Inch Dahlgrens, would serve aboard US Navy ships including USS Pensacola, USS Juniata, and USS Galena in the 1870s and 1880s.

The Whitworth Rifles of the Naval Battery on Morris Island
Four 5-Inch Whitworth Muzzle Loading Rifles were captured by the US Navy when the Blockade Runner S.S. Princess Royal was captured by USS Unadilla off of Charleston. Two of the four survive. One at West Point bearing a plaque stating that it was used on Morris Island. The other is at the Washington Navy Yard where it may have been tested in the experimental battery there.

A Medium 24-Pounder of 32 Hundredweight cast in 1826 at Bellona Foundry may be seen on the parapet of Fort Pulaski. This type of cannon was designed for the Boston-class sloops of the US Navy in the 1820s. This cannon is recorded as serving aboard USS Fairfield.

24-Pounder Dahlgren Boat Howitzer at Petersburg, Virginia
24-Pounder Dahlgren Boat Howitzer Number 388 is displayed at the Petersburg National Battlefield. According to the research reflected in Olmstead et al., this particular boat howitzer was aboard USS Granite City when that ship was captured by Confederate infantry and artillery at Calcasieu Pass, Louisiana. I do not know what subsequent Confederate service the howitzer saw nor what brought it to Petersburg.

The 32-Pounder of 32 Hundredweight at Petersburg
A 32-Pounder of 32 Hundredweight of the type manufactured for the US Navy beginning in 1846 for use as the main battery aboard smaller sloops is displayed at Petersburg National Battlefield. The 32-Pounder of 32 Hundredweight is a chambered cannon - meaning the chamber in the barrel where the propellant charge is placed is of smaller diameter than the 6.4-Inch diameter of the main portion of the barrel.

The 8-Inch Siege Howitzer of USS Pawnee
Two 8-Inch Siege Howitzers, Model 1841 (Olmstead et. al say "Pattern 1840") at the Washington Navy Yard.
Both were used in an attempted ambush of USS Marblehead on the Stono River on Christmas Day, 1863. One was subsequently carried as a pet aboard USS Pawnee.

The Cannons of the North Carolina State Capitol

Sunday Aboard USS Richmond in 1890
A set of six photos taken aboard USS Richmond on a Sunday - likely in 1890 - show a wealth of details about the Old Steam US Navy. The high resolution photos show facial expressions, equipment, arms, and more aboard a ship little changed since its service in the American Civil War.

Two 9-Inch Dahlgren cannons are displayed at Webster Rural Cemetery in Webster, New York.

Originally part of twenty such cannons sent to Sackets Harbor, the reason that these cannons were sent in 1864 remains a bit of a mystery. Sackets Harbor is a beautiful and historic site on Lake Ontario.

The carronade represents the six carronades shipped from the Gosport Navy Yard in 1861 to be mounted for flank defense in the counterfire galleries of the fort.

A 4-Inch Rifle manufactured by Fawcett, Preston, and Company of Liverpool which was used by the Confederates near Fort Fisher until captured by the US Navy on August 23rd, 1863 is displayed in Raleigh, North Carolina. This cannon may (or many not) be a “Blakely Rifle”.

The Cannons of Fort Macon
Fort Macon on Bogue Banks in North Carolina is a beautifully preserved and restored Third System fort which has been operated as a state park since 1924. Over the last decades the Friends of Fort Macon have raised money to rearm the fort and in so doing has made a very significant contribution to the historical interpretation of the fort. For those who are interested in American Seacoast Artillery, Fort Macon is a fascinating site to visit.
