In the assault crossing of the Senio during the final offensive in Italy in 1945, dummy barrages were used to confuse the enemy, either misleading them as to the line of attack or drawing them out of shelters as the barrage passed, expecting an infantry assault, only to catch them with a renewed barrage or air attacks. On Monte Sole, U.S. artillery fired probably its heaviest barrage of the war, 75,000 shells in a half-hour to clear the advance of the South Africans.
