USS Choctaw (1856)

USS Choctaw (1856) was a large (1,004-ton) steamer built for the merchant service, but acquired by the Union Navy during the second year of the American Civil War.

Choctaw, with her crew of 106, was outfitted by the Navy as a ram with heavy rifled guns and was used both as a gunboat and as a ram on the rivers of the Confederate States of America.

Built in Indiana in 1853, launched in 1856
Choctaw, a sidewheel steamer, was the first ship of the United States Navy to be named for the Choctaw Indian tribe, formerly of Alabama and Mississippi, now resident in Oklahoma.

She was built for the merchant service; her keel was laid down at New Albany, Indiana, in 1853. She was launched in 1856. She was purchased by the United States Army in 27 September 1862 and converted into an ironclad ram, then transferred to commissioned into the United States Navy at St. Louis, Missouri on 23 March 1863 with Lieutenant Commander Francis M. Ramsay in command.

Civil War operations
From 23 April 1863, until the end of the war,  Choctaw  operated in the Mississippi River and its tributaries. Between 29 April and 1 May 1863, she stood up the Yazoo River for a feigned attack on Haynes' Bluff, Mississippi, designed to prevent the Confederates from reinforcing Grand Gulf. During this action, she was struck 53 times.

Remaining in the Yazoo, she took part in attacks with the Union Army which led to the destruction of Confederate works at Haynes' Bluff and the burning of the navy yard and ships lying there, at Yazoo City, between 18 and 23 May.

On 6 and 7 June, she joined in repelling a Confederate attack at Milliken's Bend, Louisiana, after which she rescued a large number of Confederates from the river and sent them in as prisoners.

Between 7 March and 15 May 1864, she took part in the operations leading to the capture of Fort DeRussy.

Post-war decommissioning
Choctaw  arrived at Algiers, Louisiana, on 20 July 1865, and was placed out of commission on 22 July 1865. She was sold at New Orleans, Louisiana on 28 March 1866.
