In the early 1200’s, Moorish allies of the Holy Roman emperor Frederick II were attacking Assisi. The city was distraught and had no chance of defending itself against its attackers. St. Clare, who was very sick at the time, asked the convent chaplain to elevate the Monstrance holding the Blessed Sacrament high in a window while she fervently prayed for protection. Miraculously, the invaders were were struck with fear and they fled leaving Assisi unharmed.
