It was two o'clock before the fresh arrangements were completed and the boats put out. They had gone but a short distance when the anxious watchers in St. Nicholas learnt by the dull, confused sound that came across the water, that the attack was, in spite of the failure of the plan to take the bridge silently across, to be persevered in. A cannon was at once fired to give notice to the other batteries to be in readiness, and as soon as the dark mass of boats was made out the guns of the fort opened a destructive fire upon them, and a moment later were seconded by those from the fortress; these, however, were at present being fired almost at random, as the Turkish boats could not be made out at that distance. Now that all need for concealment was at an end, the Turkish war cry rose shrilly in the air, and the boatmen bent to their oars. The great cannon at St. Anthony's Church hurled their tremendous missiles at the tower, seconded by the fire of a number of other pieces that had in the darkness been brought down almost to the water's edge.
