Alarmed by these incidents, Coloman forbade the crusaders who arrived under the leadership of Count Emicho in the middle of July to enter Hungary. Ignoring the king's order, they broke through the defensive lines and laid siege to Moson. Their catapults destroyed the walls in two places, enabling them to storm into the fortress on 15 August. Coloman made preparations to flee to Rus', fearing that the crusaders would occupy the whole country. However, for no apparent reason, a panic broke out among the attackers that enabled the garrison to carry out a sortie and rout them. Modern scholars agree that rumours about the sudden arrival of Coloman's army frightened the crusaders off from the fortress. According to Albert of Aix, contemporaneous Christians thought that Emicho's defeat was a punishment that God inflicted on the pilgrims because they had massacred many Jews "rather from greed for their money than for divine justice".
