It must be remembered that they grew suddenly panic-stricken in finding that of all those who went in under the city walls by the mine on which they had set such great store, none came back, and that the sounds of panic which had first broken out within the city soon gave way to cries of triumph and joy. And it must be carried in memory also that these wretched rebels were without training worthy of the name, were for the most part weaponed very vilely, and, seeing that their silly principles made each the equal of his neighbour, were practically without heads or leaders also.
