CSS Arkansas had construction started in the arsenal in Memphis on August 24, 1861.
However, since Union Army approached Memphis before completion of CSS Arkansas,it was divided into the east from the lower stream of the town in Memphis in April, 1862, moved to the Yazoo River which winds south and joins Mississippi River by superior [ of the town of a Vicksburg ], and completed in a town Greenwood(Mississippi) in the path of a river covered with the forest.
After completion became a defence hand from the river of a Vicksburg by a Virginia type Casemate Ironclad as seen.Her sister ship is CSS Tennessee.
By the time CSS Arkansas went into the town of a Vicksburg from Greenwood, it challenged to the naval battle (15.07.1862), but the fleet of Union Army was not able to sink Arkansas.
Then, an attack (22.07.1862) by USS Essex of Union Army and the USS Queen of the West to CSS Arkansas with which a Vicksburg was filled is delivered.
Finally CSS Arkansas sorties for the Baton Rouge recapture.
However, it exploded and sank by bombardment of USS Essex which caused the engine failure and sortied in the riverside for stranding and interception on the way to Baton Rouge.
