The Intelligent Whale

Beware the vicious Intelligent Whale, a sleek marine-killer-machine of wood and metal. Construction on the Whale was completed in 1866, for use in the civil war, which unfortunately had just ended. The sub didn't work anyway; it failed all of its trials. To top it all off, the sub's jinxed owner was murdered just a few short years later by the jealous ex-lover of his mistress.
