4. Mountain Howitzer in the Museum
This specimen was cast by Cyrus Alger of Boston, Massachusetts in 1863. It has registry number 254, and foundry number 1302. It weighed 221 pounds when inspected by T. J. Rodman for acceptance. While it is very unlikely this particular howitzer was at Fort Sumter during the war, photographic evidence indicates the Confederates used weapons of this type.
