SMS Prinz Adalbert

Built in 1864 in France for the Confederate States Navy, but the sale was prohibited by emperor Napoleon III. It was sold instead to the Prussian Navy. It was a ram ship, but it saw little action. It was discovered that the wood had rotted, so the ship was removed from service in 1871 and scrapped in 1878.
