Wingard of New Orleans announced he had invented a powerful new weapon that would utterly destroy any naval vessel, iron or otherwise, "so as to leave no trace of them in their former shape." Wingard was coy about the exact means by which his weapon operated. He would only say that it projected a "nameless force," which somehow involved the use of electricity, applied without any direct connection between the machine and the object to be destroyed -- and it supposedly worked at a distance of up to five miles, far beyond the range of any other gun or cannon. In other words, this was a nineteenth-century version of a death ray. Wingard claimed that a few ships outfitted with his weapon would be able to dominate all the other navies in the world combined. In fact, he anticipated that his weapon would mean the end of naval warfare altogether, since the first navy to acquire it would become invincible and reign supreme.
