As they passed along the lanes and alleys which opened into the great street, or looked down the canals, whose polished surface gleamed with a sort of ebon lustre through the obscurity of night, they easily fancied that they discerned the shadowy forms of their foe lurking in ambush and ready to spring on them. But it was only fancy; and the city slept undisturbed even by the prolonged echoes of the tramp of the horses and the hoarse rumbling of the artillery and baggage-trains.
