First World War and the American Civil War are three of the many historical topics I've explored (especially from a purely military perspective) by reading specific books on the subject. The information found online (including Wikipedia) is essentially accurate and comprehensive.
It would be interesting to delve deeper into the torpedo topic.
In the English translation, I see that you define the term torpedo as both the underwater weapon attached to the pole and integral with the submersible unit, and the self-propelled underwater weapon.
We Italians have two distinct terms, so we wouldn't have any doubts.
I believe that, if the question is formulated with the term "torpedo" (which includes both types of weapon, although different), the Hunley submarine should be included, and therefore the correct answer is Pat's.
In my opinion, interpreting your term.
