From the record
“USS Tecumseh was a Canonicus-class monitor built for the United States Navy during the American Civil War. Although intended for forthcoming operations against Confederate fortifications guarding Mobile Bay with Rear Admiral David Farragut's West Gulf Blockading Squadron, Tecumseh was temporarily assigned to the James River Flotilla in April 1864.”
