Barrage (artillery)

A barrage is a particular method of delivering massed artillery fire from a few or many batteries. Individual guns or howitzers are aimed at points, typically 20–30 yards (18–27 m) apart, along one or more lines that can be from a few hundred to several thousand yards long. The lines are usually 100 yards (91 m) apart and fire is lifted from one line to the next and one or several lines may be simultaneously engaged by different firing units. The artillery usually fired at a continuous steady rate, using high explosive or shrapnel shells.
