British Coehorn Mortar of 4.6-inch From Rudyerd Circa 1780
From the beginning of time, improved defenses have encouraged development of new offenses. When fortifications became too strong to breach by direct fire, high angle plunging “vertical” fire was adopted. At Namur in 1692 the Dutch under Manno, Baron van Coehoorn, faced the French under his rival, Marshall Vanban. During the siege Coehoorn introduced lightweight, short-range bomb-throwing mortars. This is the earliest Coehorn Mortar we offer. It has been patterned after an early British design found in Course of Artillery, 1793 by C.W. Rudyerd. Pictured is one we did for Fort Necessity. Although the original bore is 4.6-inch, Fort Necessity requested only a 2.5-inch bore.
