USS Carondelet was a gunboat constructed for the War Department by James B. Eads during the American Civil War. It was named for the town where it was built, Carondelet, Missouri. Carondelet was designed for service on the western rivers, with a combination of shallow draft and variety of heavy guns, she was suited for riverside bombardment and ship-to-ship combat against Confederate gunboats.
Between January and October 1862, Carondelet operated almost constantly on river patrol and in the capture of Fort Henry and Fort Donelson in February; the passing of Island No. 10 and the attack on and spiking of the shore batteries below New Madrid, Missouri, in April; the lengthy series of operations against Plum Point Bend, Fort Pillow, and Memphis, Tennessee, from April through June, and the engagement with on 15 July, during which Carondelet was heavily damaged and suffered 35 casualties.
Union Navy service
Transferred to Navy control with the other ships of her flotilla on 1 October 1862, Carondelet continued the rapid pace of her operations, taking part in the unsuccessful Steele's Bayou Expedition in March 1863. One of those to pass the Vicksburg and Warrenton, Mississippi batteries in April 1863, Carondelet took part on 29 April in the five-and-a-half hour engagement with the batteries at Grand Gulf. She remained on duty off Vicksburg, bombarding the city in its long siege from May to July. Without her and her sisters and other naval forces, the great operations on the rivers would not have been possible and the Federal victory might not have been won. From 7 March to 15 May 1864, she sailed with the Red River Expedition, and during operations in support of Union Army movements ashore, took part in the Bell's Mill engagement of December 1864. For the remainder of the war, Carondelet patrolled in the Cumberland River.
Commanding Officers
Carondelet had several commanding officers over the duration of her service. During the Civil War four of Carondelets crew members were awarded the Medal of Honor: Signal Quartermaster Matthew Arther for actions at the Battles of Fort Henry and Fort Donelson, February 1862; Seaman John Dorman for actions in various engagements; Fireman Michael Huskey, for actions during Steele's Bayou Expedition, March 1863; and Coxswain John G. Morrison, for actions in the engagement with CSS Arkansas, 15 July 1862.
In 1873, shortly before she was to be scrapped, a flood swept Carondelet from her moorings in Gallipolis, Ohio. She then drifted approximately 130 miles down the Ohio River, where she grounded near Manchester, Ohio. Her ultimate fate remained unknown until a May 1982 search operation by Clive Cussler's National Underwater and Marine Agency pinpointed the location of the wreckage, just two days after a dredge passed directly over the wreckage, demolishing most of the wrecked vessel.
Armament
Like many of the Mississippi theatre ironclads, USS Carondelet had its armament changed multiple times over life of the vessel. To expedite the entrance of Carondelet into service, she and the other City-class gunboats were fitted with whatever weapons were available; then had their weapons upgraded as new pieces became available. Though the 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.
