At length Bourbon had drawn sufficiently near to use his artillery with effect, and having erected his batteries, he opened a tremendous fire upon the portion of the walls extending from the Porte d'Aix to an old Franciscan convent. The besieged immediately replied, and every cannon garnishing the ramparts, bastions, and towers that could be rendered available against the assailants was brought into play. Even a monstrous piece of ordnance, appropriately enough called “The Basilisk,” thundered from the hill surmounted by the clock-tower. This huge cannon, supposed to be the largest then fabricated, projected shot of a hundred-weight, and required sixty men to replace it after each discharge. But its unwieldy size prevented good aim from being taken, and the ponderous shot, discharged at long intervals, could be easily avoided. The smaller guns, however, were better served and directed, and caused considerable destruction among the assailants. Ere many hours, however, a breach had been made in the walls, but Bourbon hesitated to order an immediate assault, deeming the aperture not wide enough. “I would it were possible to obtain exact information of the state of the city,” he remarked to Pomperant, as he entered his tent with the latter. “Leave that to me, my lord,” said Pomperant. “I will bring you the information you require.” “You!” exclaimed Bourbon, in surprise. “How will you get into the city?” “The task is not easy, I admit,” replied Pomperant. “I do not mean to swim across the moat, and attempt to scale the walls in the face of the arquebusiers, but I think I can manage to enter the city from the sea-side, where it is less guarded.” “But to do this you must escape the fleet--elude the vigilance of the sentinels on the walls of the Chateau de Saint Jean--and lastly, you must raise the chain that protects the entrance to the harbour. It cannot be done. It were easier to penetrate the city by the breach made by my guns.” “Difficult as the task may be, I am ready to undertake it,” rejoined Pomperant. “Will you go alone?” “No; I will take Hugues with me. I can trust him.” Bourbon did not attempt to dissuade him, and at nightfall Pomperant, attended by Hugues, started on the expedition, and rode to that part of the coast where the German lanz-knechts were encamped. The night was dark and favourable for the enterprise. As he was accompanied by the Comte de Hohenzollern and a guard, no interruption was offered him by the sentinels stationed at various points, and he soon reached the shore, and proceeded to a little creek in which a fishing-boat was moored. Instantly dismounting, and consigning his horse to one of De Hohenzollern's soldiers, Pomperant embarked in the boat with Hugues, who took the oars and rowed cautiously along the coast, making for a rocky headland, which screened the entrance of the harbour.
