In 1864 the Charles Knapp Fort Pitt Foundry in Pittsburg cast some very large cannons, the XX-inch Rodman Gun. These huge cannons weighed 116,000 (also said to be 115,000) pounds and the carriage weighted another 36,000 pounds. These cannons could fire a thousand pound projectile up to 5 miles. In the world of Civil War guns, these were monsters. To the great relief of some horses, these would not normally be considered field artillery to move with an army.
