3 inch Ordnance Rifle

Description

The second most common rifled field artillery in both Armies generally, and the most common on the Maryland Campaign, the 3 inch Ordnance gun was made of hammer-welded, formed, machined iron. It was popular because of its accuracy and reliability, at least those examples built in Federal shops. Less precise machining and lower-grade iron gave their Confederate counterparts more trouble. Those built by the firm of Burton and Archer were know to be problematic.

Employment at Sharpsburg

There were probably 93 3" Ordnance Rifles in Federal Service on the Maryland Campaign, and at least 48 in Confederate batteries.
