Two days afterwards Marseilles was invested by Bourbon. The main body of the Imperial army occupied the heights overlooking the city from east to west. The lanz-knechts, under the Counts de Hohenzollern and De Lodron, were placed near the shore, and a division of the Spanish infantry, under Del Vasto, was stationed on the plain of Saint Michel, on the road to Aubagne.

On the side of a hill on the north, about four hundred toises from the walls, stood the chapel and hospital of Saint Lazare, and it was under their shelter that Bourbon and Pescara fixed their tents. From this point operations were commenced against the beleaguered city, and trenches opened in the direction of that part of the walls which had been judged to be weakest. The pioneers laboured during the night, and were protected by gabions and mantelets, but they suffered severely from the fire of the besieged. Frequent sorties were made by Renzo da Ceri, and many a bloody conflict took place near the trenches; but these engagements uniformly resulted in the discomfiture of the besieged, and consequently the works advanced slowly but steadily.

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.

In a few minutes the boat had got under cover of the rock, and escaped the notice of the sentinels stationed on the ramparts of the fort above. No wind was stirring, and only a slight undulation was perceptible on the surface of the tideless sea.

While Hugues kept the little vessel moving, Pomperant, who was seated in the stern, peered through the gloom to see whether any danger was at hand. He could just discern the French fleet lying between the group of islands and the mouth of the harbour, and concluded from the sounds that reached him that several boats, were leaving the ships. At once determining on the course to be pursued, he ordered Hugues to move noiselessly on, and keep close to the rock until he gained the entrance of the harbour. This was done, and ere long the boats, upwards of a dozen in number, came up. They were filled with armed men, doubtless sent by Doria or La Fayette to strengthen the garrison of the city.

As soon as the boats had passed, Hugues followed in their wake, and speeded between the rocky heights guarding the narrow channel. The boats were of course challenged by the sentinels stationed on the forts on either side, but the answers being satisfactory, they were allowed to pass. Hugues also passed without exciting suspicion.

It has already been mentioned that a heavy chain was drawn across the mouth of the harbour, and a short delay occurred while this obstacle was removed. Several men were standing with torches on the rocky steps aiding those who were engaged in lowering the ponderous chain, while higher up stood a guard of arquebusiers.

At length, the chain being dropped and the passage free, the throng of boats pushed into the harbour, and close behind them came Hugues, hoping in the confusion to elude observation. But the manouvre, though skilfully managed, did not escape detection. The torchlight revealed the intruders, and an authoritative voice from the steps called out, “Hola! who goes there? What boat is that? Stay, and give an account of yourselves.”

Hugues paid no attention to the summons, which was reiterated by other voices, but hurrying on more rapidly than before, contrived to place some of the other boats between him and the arquebusiers, so that the latter could not fire, and in another minute he had disappeared in the gloom. Luckily, the soldiers in the boats, though they heard the shouts, disregarded them, and pursued their course without stopping.

As soon as it was practicable, Hugues disengaged himself from his dangerous companions, and while they made their way to a wharf on the left of the basin, he struck across to the opposite side, where a landing was effected without molestation. At this time the harbour was entirely destitute of ships, as any vessels lying there would, of course, have been exposed to the guns of the hostile batteries. Hence the wharf at which Pomperant and Hugues landed was wholly deserted. In fact, there were very few buildings near the spot, for the city had not as yet extended to this side of the harbour.

The walls, however, which surrounded the basin were not far off, but the place was gloomy, and the attention of the sentinels was elsewhere directed. After securing the boat to the wharf, Pomperant and Hugues made their way as quickly as they could round the head of the basin, which, as we have before stated, was then little better than a swamp, and, reaching the city, plunged into a narrow street communicating with the principal quay.

Just as they had entered this street, which was only lighted by an occasional lantern hung before a door, the sound of martial footsteps warned them that a patrol was approaching, and fearing they might be stopped and questioned, they withdrew into an archway till the guard had passed by. They then pursued their way along the street, whieh gradually mounted a hill, until they came to an open space, in the midst of which a troop of cavalry was drawn up. This band was surrounded by a crowd of citizens, some of whom carried torches, and in its leader, who was arrayed in a complete suit of armour, but whose beaver was raised, Pomperant instantly recognised the stern dark countenance of Renzo da Ceri. He was haranguing the assemblage, and Pomperant, closely followed by Hugues, mingled with the crowd to hear what he said.

“Be of good cheer, my friends,” he cried. “The danger is past. In a few hours the breach will be repaired, and the measures I have taken for the defence of the city are so complete that we may laugh at the threats of the foe. The traitor Bourbon boasted that he would be master of the city this night, and it is well for you that he did not dare to make good his threat.”

The mention of Bourbon's name was received with a perfect storm of yells and execrations, and when this had subsided Renzo went on.

“We have an enemy who will show us no mercy,” he said. “Were he to take the city, it would be sacked by his soldiery.”

“That is false!” shouted Pomperant.

“Who spoke?” demanded Renzo, fiercely. “Let him show himself, that I may see who dares gainsay my assertion.”

There was a moment's pause, during which glances were turned in the direction of the imprudent speaker, but he could not be discovered.

“Whoever uttered those words must be a friend of Bourbon,” pursued Renzo. “I repeat, that it is the traitor's intention to deliver this city to his savage host, and I therefore exhort you to fight to the last in defence of those dear to you. Save your wives and daughters from dishonour. None will be spared.”

“Again I say it is false!” vociferated Pomperant.

“Seize the traitor, and bring him before me,” roared Renzo.

An attempt was made to obey the injunction. Several persons were seized, and, amid the confusion that prevailed, Pomperant and Hugues extricated themselves from the throng, and passed into a side-street, just as dark and narrow as that they had recently traversed. From the noise and shouts which reached them, it was clear the assemblage had just broken up, and presently Renzo, with his mounted guard, rode down the street, followed by a number of men, evidently part of the assemblage who had been listening to his harangue.

Pomperant and Hugues allowed themselves to be borne on by the stream, and at length issued forth into a wide esplanade ornamented with plane-trees, which here intervened between the city and the walls. On the left of this open space, and within a short distance of the ramparts, stood the bishop's palace, a large and monastic-looking structure. Close beside it was the venerable church of Saint Cannat. The palace and the church were the only two buildings near this angle of the walls, and it was quite evident to Pomperant that if Bourbon could once obtain possession of them, the city must fall. The marvel was, that experienced engineers like Renzo da Ceri and Chabot de Brion should allow them to remain. Close to the walls where the breach had been made a large body of lansquenets were collected, and with them was a band of armed citizens. The ramparts also were thronged with arquebusiers, and the canonniers remained standing near their guns.

Within a few yards of the breach a battery had been reared, on which three large cannon were planted, ready for service in case the assault should be made. But already the repairs were more than half accomplished. The gap was filled up with huge stones, pieces of timber, fascines, and other matters, and banked up with earth. A hundred men at a time were engaged on the operations, and a hundred others stood by ready to relieve them, so there was no pause. Officers were stationed on the walls on either side of the breach, giving orders and superintending the work.

After watching the proceedings for some time with an interest such as a soldier only can feel, and satisfying himself that the breach would infallibly be repaired before daybreak, Pomperant moved away. Following the course of the walls, he examined them as well as he could in the gloom.

Proceeding in this manner, he made the circuit of the city; and the result of his scrutiny was, that it was in a perfect state of defence. He remarked that the gates exposed to attack were blocked up, and protected on the inside by parapets and batteries. He also noticed that all the ramparts were garnished with cannon, and that the sentinels everywhere were doubled. The bastions, indeed, were thronged with armed men, and it was evident that the whole garrison was on the alert. Officers, accompanied by a mounted guard, were continually riding from gate to gate, while others made their round on the battlements to see that good watch was kept. Patrols, both horse and foot, were likewise moving about in every direction. Enough was seen by Pomperant to convince him that a most energetic defence would be made, and that it would be long before the place could be taken.

Having completed his examination of the walls, he re-entered the city, and shaped his course, as well as he could, in the direction of the mound, on the summit of which stood the clock-tower. As both he and Hugues were unacquainted with Marseilles, they more than once lost their way; and though there were plenty of people abroad they did not dare to question them, lest it should be found out that they were strangers. Pomperant had begun to despair of reaching the mound, when he unexpectedly came upon it.
