Surrounded And Besieged By Devils

Once at the Place of the Portiuncula, when St. Francis was praying devoutly, as was his custom, by divine revelation he saw the whole Place surrounded and besieged by devils, as by a great army. But not one of them was able to enter into the Place because the friars were so holy that the devils could find no one to whom they could gain admittance.
