What religious actions did crusaders perform before attacking Jerusalem in 1099?

Before launching their final assault on Jerusalem in July 1099, the crusaders engaged in specific religious acts to prepare for the battle. On July 8, the army observed a strict fast. Following this, the entire force, led by the clergy, marched in a solemn procession around the city walls. The procession concluded at the Mount of Olives, where Peter the Hermit preached to the soldiers.12

These actions were consistent with the nature of the Crusades, which were viewed by participants as a form of armed pilgrimage and a means of penance for sin. By performing these rituals, the crusaders sought to align their military efforts with their religious objectives, reflecting the era's belief that their success was a result of divine intervention.34512
