USS Louisville (1861)
USS "Louisville" was a gunboat constructed for the U.S. Army by James B. Eads during the American Civil War. (While initially owned by the Army, the City-class gunboats were commanded by U.S. Navy officers, and were eventually transferred to the Navy.) "Louisville" was built at St. Louis, Missouri, by James B. Eads in 1861, under contract with the War Department for the price of $89,000. Designed by U.S. Navy "Constructor" (Naval Engineer) Samuel M. Pook, she was accepted 15 January 1862; and commissioned 16 January 1862, Commander Benjamin M. Dove, USN, in command. Despite being  designed by naval personnel, budgetary concerns led the War Department to fund construction of "Louisville" with Army funds. As such, she was turned over to Army command upon completion and joined the Army's Mississippi River Squadron. Eventually the entire western river flotilla would be transferred to Navy command. Operational history. "Louisville" assisted the Army in the capture of Fort Donelson on the Cumberland River 14 to 16 February 1862. From 1 to 5 March, she aided in the occupation of Columbus, Kentucky, the "Gibraltar of the West." Departing Cairo, Illinois, 14 March, she served in the capture of Island  No. 10 and New Madrid, Missouri, through 7 April, and helped to prevent southern ships from ascending the river. In May, "Louisville" was ordered to Fort Pillow and participated in the Battle of Memphis 6 June. Commanded by Rear Admiral Charles Henry Davis, her squadron captured and sank the Confederate Mississippi flotilla. On 15 June, she attacked the upper batteries at Vicksburg, before shifting efforts to the White River, departing Helena, Arkansas, 5 August. Escorting and to the mouth of the river, she met little resistance. In late September 1862 she was transferred to the Navy and assigned a new  commanding officer, Lieutenant Commander Richard W. Meade. After escorting transport "Meteor", disembarking troops at Bledsoe's and Hamblen's landings 21 October, "Louisville" returned to Helena to join the gunboat fleet, Mississippi Squadron. She joined , , , , , , , and later in the month on an expedition up the White River in support of Major General William T. Sherman's army. "Louisville" captured the steamer "Evansville" near Island No. 36 on 1 November. Now under the command of Lieutenant Elias K. Owen, "Louisville" aided in the capture of Fort Hindman, Arkansas Post, 4 to 11 January 1863, and formed part of the expedition through  Steele's Bayou, 14 to 28 January. She was ordered to the Yazoo River the 31st and moved to stop Confederates felling trees across the bayou on 21 March. She then turned her attention to the batteries on the river, running past those at Vicksburg on 16 April, and engaging the lower ones on the 29th. She joined , and on that date, silencing the guns of the fort on Grand Gulf and helping to establish the siege which forced Vicksburg's surrender 4 July 1863. From 12 March to 22 May 1864, "Louisville" joined in the expedition up the Red  River. On 2 June she engaged Confederate batteries seven miles below Columbia, Arkansas, silencing the guns. She landed Union troops at Sunnyside 6 June and anchored off Shipwith's Landing the 20th, to learn that Confederates were traveling upriver with a heavy force, and had crossed Cypress Creek and Bartholomew's Bayou 20 June with cavalry, infantry, and artillery. On learning that Parsson's brigade was 10 miles back of Gaines' Landing, providing reinforcements, "Louisville" departed immediately for that point, and helped break up the Confederate attack. "Louisville" continued service on the Mississippi River until decommissioning 21 July 1865. She  was sold at public auction at Mound City, Illinois 29 November 1865. Four of her sailors were awarded the Medal of Honor for their service in the war: Boatswain's Mate Charles Bradley, Boatswain's Mate James Byrnes, Coxswain Timothy Sullivan, and Captain of the Forecastle William Talbott. Armament. Like many of the Mississippi theatre ironclads, "Louisville" had its armament changed multiple times over life of the vessel. To expedite the entrance of "Louisville" into service, she and the other City-class ships were fitted with whatever weapons were available; then had their weapons upgraded as new pieces became available . Though the 8-inch Dahlgren smoothbore cannons were fairly modern most of the other original armaments were antiquated; such as the 32-pounders, or modified; such as the 42-pounder "rifles" which were in fact, old smoothbores that had been gouged out to give them rifling. These 42-pounder weapons were of particular concern to military commanders because they were structurally weaker and more prone to exploding than purpose built rifled cannons. 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.
