USS Shiloh (1865)
USS ''Shiloh'' was a single-turreted, twin-screw monitor that was slated to enter service with the United States Navy. The contract for her construction was awarded on 24 June 1863 to George C. Bestor of Peoria, Illinois. Her keel was laid down later that year at the yard of Charles W. McCordat of St. Louis, Missouri. However, while ''Shiloh'' was still under construction, , one of the first of the ''Casco''-class monitors to be launched, was found to be unseaworthy.
==Design revisions==
Though the original designs for the ''Casco''-class monitors were drawn by John Ericsson, the final revision was created by Chief Engineer Alban C. Stimers following Rear Admiral Samuel F. Du Pont's failed bombardment of Fort Sumter in 1863. By the time that the plans were put before the Monitor Board in New York City, Ericsson and Simers had a poor relationship, and Chief of the Bureau of Construction and Repair John Lenthall had little connection to the board. This resulted in the plans being approved and 20 vessels ordered without serious scrutiny of the new design. US$14 million was allocated for the construction of these vessels. It was discovered that Stimers had failed to compensate for the armor his revisions added to the original plan and this resulted in excessive stress on the wooden hull frames and a freeboard of only . Stimers was removed from the control of the project and Ericsson was called in to undo the damage. He was forced to raise the hulls of the monitors under construction by to make them seaworthy.
On 25 June 1864, the Navy Department ordered ''Shiloh's'' builder to raise her deck to give her sufficient freeboard, then on 17 June 1865, after the end of the Civil War had prompted an American naval retrenchment, work on ''Shiloh'' was ordered suspended.〔 Nevertheless, it was decided to proceed with her launching; and an unsuccessful attempt to get her off the ways was made on 3 July 1865. After much labor, the ship finally entered the water 11 days later.〔
