Thanks for that Doyle.
I checked the ORN but there is no exact indication of the date in those volumes.
The DICTIONARY OF AMERICAN NAVAL FIGHTING SHIPS also supports the October 9, 1863 date, "at or near Little Rock." According to this source, she was sent up the White River in April, 1862 for operations around that time. Then, according to DANFS, she remained inactive, I assume on the same river, until she was burned.
What are your sources for the September, 1863 date?
