Though Bourbon's tent was concealed from view, its position was marked by the proud banner floating above the walls of the little chapel of Saint Lazare. Pescara's tent was likewise hidden by the sacred edifice, but his banner was as conspicuous as that of Bourbon. The course of the trenches, which advanced in zig-zags towards the walls, could be readily traced. The men were at the battery, waiting orders to open fire. From the battery Pomperant naturally turned to the ramparts which it faced, and he saw that the breach had been completely repaired, and was defended by a parapet, behind which cannon were planted. The work was a marvel of industry, and showed the spirit that animated the besieged. If all were thus early astir in the camp of the Imperial army; if the men were mustering and preparing for action; if the artillerymen were at their posts at the various batteries, and both horse and foot in readiness--so also were the besieged. Bastions, ramparts, and towers were thronged with soldiers. A troop of cavalry, commanded by Chabot de Brion, was drawn up near the bishop's palace. Close beside them was a company of pikemen. Detachments of horse and foot were likewise stationed near the Porte d'Aix, and all the other gates not blocked up. In short, every possible preparation for energetic defence was made. As yet not a gun had been fired by the besiegers, and Pomperant waited with breathless impatience for the commencement of hostilities. There was something ominous in the silence that now prevailed. All the martial sounds recently saluting the ear had ceased. Drums and trumpets were mute. The stillness was undisturbed, for the morning was calm, and the numerous banners on walls and towers hung motionless. After running his eye along the ramparts, crowded with arquebusiers and pikemen, Pomperant once more turned his gaze towards the little chapel on the hillside. At that moment came forth a troop of knights, sheathed in polished armour. At their head rode Bourbon and Pescara, both distinguishable, even at that distance, from the splendour of their accoutrements and the rich housings of their steeds. Each had a short battle-axe at his saddle-bow--each carried a bâton, in token of command. As the knightly troop rode slowly down the hill towards the battery, its movements were watched with keenest interest by thousands of soldiers from the ramparts and towers of the city. Still, not a gun was fired. At this moment, Pomperant, whose attention had been for some time diverted by other objects from the battery near which he stood, was reminded of its proximity by a bustle among the artillerymen who had charge of the monster cannon, and, looking in that direction, he saw they were about to fire; and the match being applied, he was almost stunned by the tremendous detonation that ensued.
