The victory of Ivry had a great effect in France and in Europe, though not immediately, and as regarded the campaign of 1690. The victorious king moved on Paris and made himself master of the little towns in the neighborhood with a view of besieging the capital. The investment became more strict; it was kept up for more than three months, from the end of May to the beginning of September, 1590; and the city was reduced to a severe state of famine, which would have been still more severe if Henry IV. had not several times over permitted the entry of some convoys of provisions and the exit of the old men, the women, the children, in fact, the poorest and weakest part of the population. “Paris must not be a cemetery,” he said: “I do not wish to reign over the dead.” In the meantime, Duke Alexander of Parma, in accordance with express orders from Philip II., went from the Low Countries, with his army, to join Mayenne at Meaux, and threaten Henry IV. with their united forces if he did not retire from the walls of the capital. Henry IV. offered the two dukes battle, if they really wished to put a stop to the investment; but “I am not come so far,” answered the duke of Parma, “to take counsel of my enemy; if my manner of warfare does not please the king of Navarre, let him force me to change it instead of giving me advice that nobody asked him for.” Henry in vain attempted to make the duke of Parma accept battle. The able Italian established himself in a strongly entrenched camp, surprised Lagny and opened to Paris the navigation of the Marne, by which provisions were speedily brought up. Henry decided upon retreating; he dispersed the different divisions of his army into Touraine, Normandy, Picardy, Champagne, Burgundy, and himself took up his quarters at Senlis, at Compiègne, in the towns on the banks of the Oise. The duke of Mayenne arrived on the 18th of September at Paris; the duke of Parma entered it himself with a few officers and left it on the 13th of November, with his army on his way back to the Low Countries, being a little harassed in his retreat by the royal cavalry, but easy, for the moment, as to the fate of Paris and the issue of the war, which continued during the first six months of the year 1591, but languidly and disconnectedly, with successes and reverses see-sawing between the two parties and without any important results.
