Thanks! That site answers the questions regarding the Huntsville and the Tuscaloosa, as they became the floating batteries of the same names.

However, it only deepens the mystery of the character, disposition, and names of the Tombigbee built ironclads. I thought surely somebody knew, but this indicates that this information still remains unknown by the ironclad experts.

The site states:

Unnamed (Oven Bluff #1): Similar to Huntsville. One of the "Bigbee boats" on the Tombigbee River.

Unnamed (Oven Bluff #2): Similar to Huntsville. Another of the "Bigbee boats."

Unnamed (Oven Bluff #3): Possibly similar to Nashville. Another of the "Bigbee boats."

I wonder what is the source for the above information? It is clear from the O.R.'s that one of these was an ironclad sloop. Also, the measurements given in the O.R.'s indicate that the two ironclad gunships being built on the Tombigbee were larger than the Huntsville, but considerably smaller than the Nashville. I strongly believe the above information from the site is in error, at least based on O.R. correspondance.

The Nashville is recorded in the O.R. correspondance as being started in Selma, but finished in Mobile. This is in error on the site, where it is stated that the Nashville was built in Montgomery and completed in Mobile.

It is interesting to note from that site that the "Baltic" was once an ironclad, but was de-claded. For the record, this vessel was constructed at Mobile and surrendered at Nana Hubbard Bluff at the end if the war.
