What do we call the daily ritual of firing at the enemy at sunrise in world war 1?

The daily ritual of firing at the enemy at sunrise during World War I is often referred to as the "dawn attack" or "dawn patrol." This practice was part of trench warfare, where soldiers would engage in artillery bombardments or small-scale assaults at first light, taking advantage of the early morning hours for surprise and visibility. It was a tactic used to test enemy defenses and maintain pressure on opposing forces.
