The original Coehorn was light enough to be moved by as few as two men, although a four-man crew was more practical for rapid movement. It proved immediately popular: the 74 used at Kaiserswerth were increased to over 300 at Bonn six months later.
The 8-inch and 10-inch siege mortars had maximum ranges of 2,225 and 2,064 yards, respectively, (Abbot 1867, pp. 39–40) and the 13-inch seacoast mortar had a maximum range of 4,300 yards, but their effective ranges were much shorter. For the 8-inch siege mortar at a range of 800 yards, about 50% of the shells would fall within a 50-yard ...

For several centuries Coehorn mortars were fired indirectly because their fixed elevation meant range was determined by the amount of propelling powder. It is also reasonable conjecture that if these mortars were used from inside fortifications their targets may have been invisible to them and therefore met the definition of indirect fire.
