If Parma could have remained with his army in France, the cause of Henry of Navarre would have been lost. But sickness was making ravages among his troops. Dissensions broke out between the Spaniards, Italians, and Netherlanders of his army and their French allies, who hated the foreigners, though they had come to their assistance. Lastly, his presence was urgently required in the Netherlands, where his work was as far from being done as ever. Therefore to the dismay of the Leaguers he started early in November on his march back. No sooner did he retire than the king took the field again, recaptured Lagny and Corbeil, and recommenced the siege of Paris, while his cavalry hung upon the rear and flanks of Parma's army and harassed them continually, until they crossed the frontier, where the duke found that affairs had not improved during his absence. Lionel had obtained permission to accompany the force which captured Lagny, and as soon as they entered the town hurried to the mercer's house. He found Jacques in possession, and learned that the family had weeks before left the crypt and reoccupied the house, but had again taken refuge there when the Huguenots attacked the town. Lionel at once went below, and was received with delight. He was now able to repay to some extent the obligations he had received from them, by protecting them from all interference by the new captors of the town, from whom the majority of the citizens received harsh treatment for the part they had taken in attacking the garrison when the Spaniards first entered. Prince Maurice's visit to the camp of Henry had been but a short one; and as soon as Parma had effected the relief of Paris, and there was no longer a chance of a great battle being fought, he returned to Holland, followed after the recapture of Lagny by Sir Ralph Pimpernel and the few survivors of his party, who were all heartily weary of the long period of inaction that had followed the victory at Ivry. They found that during their absence there had been little doing in the Netherlands, save that Sir Francis Vere, with a small body of English infantry and cavalry, had stormed some formidable works the Spaniards had thrown up to prevent relief being given to Recklinghausen, which they were besieging. He effected the relief of the town and drove off the besiegers. He then attacked and captured a fort on the bank of the Rhine, opposite the town of Wesel. At the end of the year 1590 there were, including the garrisons, some eight thousand English infantry and cavalry in Holland, and the year that followed was to see a great change in the nature of the war. The efforts of Prince Maurice to improve his army were to bear effect, and with the assistance of his English allies he was to commence an active offensive war, to astonish his foes by the rapidity with which he manoeuvred the new fighting machine he had created, and to commence a new departure in the tactics of war.
