USS Benton: Бронепарусный канонер реки Миссисипи

Gunboat of the United States Navy

USS Benton was an ironclad river gunboat in the United States Navy during the American Civil War. She was named for American senator Thomas Hart Benton. Benton was a former center wheel catamaran snagboat and was converted by James B. Eads, St. Louis, Missouri, in 1861 and commissioned February 24, 1862 as part of the Army's Western Gunboat Flotilla.

On April 29, 1861 Secretary of the Navy Gideon Welles received correspondence from James Eads concerning the viability of converting Submarine No. 7 into a riverine warship for the U. S. military. Submarine No. 7 was a snagboat built by the US Navy that had been purchased by Eads' Missouri Wrecking Company and modified to raise sunken steamboats on the Mississippi River. Both hulls of Submarine No. 7 were divided into 7 watertight compartments and Eads argued that the vessel could suffer up to 20 penetrating shot into 4 of these compartments and still stay afloat. (Other sources state she was built with 40 watertight compartments.) He argued that the vessel would be able to support a strong battery of 32 pounder cannons. His initial proposal called converting the vessel into a Cotton clad gunboat for a cost of $3,000 in cotton. His letter also described a plan to convert two other, smaller vessels and to create a naval base at Cairo, Illinois. Lacking the resources to undertake the project, Welles forwarded Eads's letter to the Secretary of War Simon Cameron. Cameron was impressed by the proposal and forwarded it to General George McClellan to implement the construction of the base. Instead of the cotton clad boat however, the US Army wanted a fleet of new ships; this became the City class ironclad fleet. Eads earned several additional contracts after impressing the authorities with his abilities during the construction of the City class. One of the vessels involved was Submarine No. 7. Eads widened the lower deck of Submarine No. 7 into a gun deck then added a second tier of accommodations. The large size of the finished vessel and this additional space led to the vessel being well suited to a flagship role. Commander William D. Porter complained that the finished vessel was too slow, and history has recorded that Eads replied that she was still fast enough to fight in. Now as the Benton, she would serve as a flagship for most of the war.

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 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. On 10 May, she was present for the Battle of Plum Point Bend where a Confederate ram flotilla ambushed the fleet, sinking the Cincinnati and the Mound City before being driven off. On June 6, Benton and the fleet, now supported by a flotilla of Union rams under the command of Colonel Charles Ellet, Jr. engaged the Confederate rams in the First Battle of Memphis where the Confederate flotilla was completely routed. In July the Benton led the fleet into an attempted engagement with the CSS Arkansas near Vicksburg, Mississippi. The attempt was a failure and Benton and the fleet were forced to retreat north of the city for the rest of the year. In October, the entire fleet was transferred from Army command to Navy command. Benton spent the remainder of the year patrolling the Yazoo River. In May, Benton returned to Vickburg to continue bombarding the city until its fall in June. By the end of the war, most of the action had been resolved in the western theater. Her last significant action was to steam back up the Red River in June to take possession of the surrendered CSS Missouri. Benton decommissioned July 20, 1865 at Mound City, Illinois. Her armor and armament were removed and she was sold November 29, 1865.
