The shot that opened the Civil War was fired from a mortar. The Coehorn Mortar was a very useful piece, for it was developed in the 16th century, and there were still a few in use in British colonial garrisons in the 1920’s.

A coehorn /ˈkoʊhɔrn/ (also spelled cohorn) was a portable mortar developed in the Netherlands by Menno van Coehoorn in 1674 and in use from the seventeenth to the mid nineteenth centuries. Unlike larger, heavier mortars, the coehorn was designed to be movable by as few as four men. By the time of the American Civil War, it was in service with both armies in twelve (4.62″) and twenty-four pound varieties.
