The artillery barrage was a calculated wall of fire designed to shield advancing soldiers.

In short: In the trenches of World War I, soldiers learned to lean on a moving curtain of steel. By firing artillery in precise, timed lines ahead of their own troops, armies created a protective barrier that suppressed enemy defenders, allowing infantry to advance under the cover of a controlled, shifting bombardment.

A barrage is a specific military tactic involving massed, sustained artillery fire directed at a series of points along a line. Unlike concentrated fire, which targets a single structure or position, a barrage aims to create a barrier that denies enemy movement or suppresses their ability to fight. These lines of fire are typically spaced 20 to 30 yards apart, with the entire zone stretching hundreds or thousands of yards. By the First World War, this technique evolved into the creeping barrage, where artillery fire moved forward in small, timed increments—often 50 to 100 yards every few minutes—to keep pace with advancing infantry.

The tactic was developed by the British Army during the Second Boer War, but it reached its peak during the First World War. Commanders realized that the primary value of the barrage was not necessarily the physical destruction of enemy fortifications, but the psychological and tactical suppression of defenders. By keeping the barrage moving just ahead of the infantry, attackers could reach enemy trenches before defenders had time to recover from the shock of the bombardment and emerge from their dugouts. This required precise, scientific planning, as a barrage that moved too slowly risked friendly fire, while one that moved too quickly left troops exposed to enemy resistance.

As warfare evolved, so did the patterns of the barrage. Defensive variants like the standing barrage were used to break up enemy attacks, while the box barrage isolated specific positions by surrounding them on three sides. By the Second World War, the barrage remained in use but became less dominant as improvements in communication and target location allowed for more flexible artillery support. While the term is now often used loosely in popular media to describe any intense artillery fire, its technical definition remains a highly coordinated, time-governed operation that fundamentally shaped the nature of 20th-century infantry assaults.
