Heedless of these sounds, Bourbon and Pescara, and those with them, remained on the heights until a sortie was made from the Porte d'Aix by a large force of cavalry, numbering about fifteen hundred men, and headed by Renzo da Ceri. They then descended to their escort, whom they had left on the farther side of the hill on the road from Aix. When Renzo da Ceri came in sight of Bourbon and his troop, and found that the force was greater than his own, he hesitated to make the attack, and eventually galloped back to the city. He was hotly pursued by Bourbon and Pescara, who, despite the cannonade directed against them from the towers, bastions, and battlements, followed him to the gate whence he had issued, and only withdrew because the drawbridge was raised. V. IN WHAT MANNER POMPERANT ENTERED MARSEILLES. |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.
