I had never heard of this ship before. In the last post I wrote that this ship was sunk while engaged with Fort Jackson guarding New Orleans.
The Maria J. Carlton was a schooner acquired by the U.S. Navy and used as a mortar boat, fitted with a 13-inch mortar and two 12-pdr. rifled howitzers. It was 178 tons, 98 feet long and 27-foot beam.
Mortars could fire up and above a target instead of directly at it..
It was purchased at Middletown, Ct. on 15 October 1861 and converted at New York Navy Yard. Commissioned 29 January 1862 with Acting master Charles E. jack commanding.
