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.

4.62-Inch Gorgas Rifle at Stony Creek, Virginia
A 4.62-Inch Siege Rifle cast by Bellona Foundry (near Richmond) in 1862 may be found in Stony Creek, Virginia. Weight of 5,360 pounds is stamped on the breech. The right trunnion reads "BF / JLA" (Bellona Foundry / Junius L. Archer).
Olmstead et al. identifies this cannon as a "Gorgas Rifle", a type manufactured by both Tredegar and Bellona. This example is the only known survivor of the type. As noted in "The Big Guns", this rifle is nearly identical to the 4.62-Inch "Gibbon and Andrews" rifle found at Fort Branch except for the latter rifle being banded and therefore eight hundred pounds heavier.
