The American Revolutionary War even had some form of submersible, though not really all that recognizeable as a submarine, and even less successful then the Civil War subs (the Hunley did manage to sink an enemy ship... along with itself).Not true: submersible vehicles saw active duty (even if not spectacularly successful duty) during the American Civil War. Though you are correct about the idea not being original to Verne: I've seen both Greek and Danish (Viking, actually) historical documents putting forward the idea, and da Vinci's Codices have some fairly detailed and forward-thinking plans - some of which were used as the basis for those Civil War subs.
