His son and successor, Lewis XIV., was a mere child. His widow, Anne of Austria, claimed the regency, and forgot that she was the sister of the King of Spain and the sister-in-law of the Emperor, in the thought that she was the widow of one king of France and the mother of another. Her minister was Cardinal Mazarin, an Italian, who had commended himself to Richelieu by his capacity for business and his complete independence of French party feeling. If he was noted rather for cleverness than for strength of character, he was at least anxious to carry out the policy of his predecessor, and to maintain the predominance of the crown over aristocratic factions; and for some time Richelieu's policy seemed to carry success with it through the impetus which he had given it. On May 19 a victory came to establish the new authority of the queen-regent, the first of a long series of French victories, which was unbroken till the days of Marlborough and Blenheim. [Sidenote: § 2. The Spaniards attack Rocroy.] The Spaniards had crossed the frontier of the Netherlands, and were besieging Rocroy. The command of the French forces was held by the duke of Enghien, better known to the world by the title which he afterwards inherited from his father, as the Prince of Condé. Next to Gaston, Duke of Orleans, the late king's brother, he and his father stood first in succession to the throne, and had, for this reason, attached themselves to Richelieu when he was opposed by the great bulk of the aristocracy. Those who placed him at the head of the army probably expected that a prince so young and so inexperienced would content himself with giving his name to the campaign, and would leave the direction of the troops to older heads. [Sidenote: § 3. Gassion and Enghien.] The older heads, after reconnoitring the Spanish position at Rocroy, advised Enghien not to fight. But there was a certain Gassion among the officers, who had served under Gustavus, and who had seen the solid legions of Tilly break down before the swift blows of the Swedish king at Breitenfeld. Gassion had learned to look upon that close Spanish formation with contempt, and he strove hard to persuade Enghien to give orders for the attack, and, truth to say, he had no very hard task. Enghien was young and sanguine, and whether he had a genius for war or not, he had at least a genius for battles. Already conscious of the skill with which he was to direct the fortunes of many a well-fought field, he heartily adopted the views laid before him by Gassion. [Sidenote: § 4. Battle of Rocroy.]
