USS Benton (1861) - Armament

Armament

Like many of the Mississippi theater ironclads, the Benton had her armament changed multiple times. Like the City-class, the Benton was fitted with a mixture of modern and antiquated weapons, then had her weapons upgraded as new pieces became available. Though the 9-inch (230 mm) smoothbore guns were modern, most of the other original armaments were antiquated, such as the 32-pounders, or modified, such as the 42-pounder "rifles" that were in fact old smoothbores that had been gouged out to give them rifling. These modified weapons were of particular concern to military commanders because they were structurally weaker and more prone to exploding than purpose-built rifled guns. Additionally, the close confines of riverine combat greatly increased the threat of boarding parties. The 12-pounder howitzer was equipped to address that concern and was not used in regular combat. By the end of the war, the Benton was one of the heaviest armed vessels in the Mississippi theater.
