About the 4.5 inch Siege Rifle
Sometimes mistakenly called a 4.5 inch Ordnance Rifle or 4.5 inch Rodman Rifle, this large siege and garrison gun actively served in Union Artillery batteries, and had a reputation for being easy to transport.
Regarding the usefulness of the 4.5 inch Siege Rifle, while detailing siege operations in the Richmond area, Henry L. Abbot wrote, "The two siege batteries of 4.5 inch Ordnance guns, which accompanied the army of the Potomac in all its movements from Fredericksburg until the final crossing of the Rapidan, were of great use, from their superior range and accuracy, in silencing troublesome field batteries and in other field service; and could be moved with the reserve artillery without impeding the march of the army."
