A barrage is a term used to describe extensive artillery fire against enemy positions. Barrages were classified as light, moderate or heavy. A light barrage amounted to six or seven shells every ten minutes. A moderate barrage was thirty shells a minute and a heavy one, fifty to sixty shells a minute.
Barrage fire is not aimed at specific targets, it is aimed at areas in which there are known or expected targets. It contrasts with a concentration, in which the guns aim at a specific target in an area typically 150â250 metres (160â270 yd) diameter.
