A "Cannon Barrage" is a military tactic that involves the simultaneous firing of multiple artillery pieces to create a concentrated area of explosive fire. This method is often used to suppress enemy forces, destroy fortifications, or provide cover for advancing troops. The barrage can be planned to target specific locations or to create a general area of destruction. The technique became prominent during World War I, where it was used extensively by both the Allied Powers and Central Powers. The effectiveness of a cannon barrage relies on precise coordination and timing, ensuring that the artillery fire overwhelms the enemy while minimizing risks to friendly forces.
