There is also Wilhelm Bauer's
Brandtaucher (incendiary diver) from first Danish-German war (1850). The ship was built for military use in mind, but she was never on a war patrol (which would not be her task anyway) and could only sink herself. But she has a score for the first sunken sub(mersible), from which the crew could escape alive (after sitting on the bottom of Kiel Bay for 6 hours).
