To his brother, as head of the house, he paid a species of obedience, as to a suzerain,—a line of conduct he pursued towards his nephew, though still a youth, on succeeding to the title. All these things considered, it is not to be wondered at that Turenne was delighted when he received the news that patents had been granted to himself and his brother (with other concessions to the elder), entitling them and their descendants to the dignities and privileges of Princes of the blood-royal. He hastened back to Paris, and was received by the Cardinal with outward signs of welcome. But breakers were ahead. The peace was a hollow one, leaving both parties in much the same condition: the Cardinal and the Parliament each preserving authority as before,—the one over the Court, the other over the people. The Prince de Condé was always at issue with the Minister, whom he treated with ill-concealed contempt; and his Eminence, wearied and perplexed by the exigencies and requirements of the great man, and maddened by his sarcasms, plotted his ruin. The Duchesse de Longueville, who watched all passing events with vigilance, chose this opportunity to renew her overtures of reconciliation to her brother; and she not only succeeded in so doing, but persuaded Monsieur le Prince to give in a half-and-half adhesion to the cause of the Fronde, in which party he had many friends, and perhaps more enemies. Among the most inveterate of the latter was the Cardinal de Retz, at this moment on friendly terms with the Court; and it was by the joint arrangement of the two Churchmen that a step was taken which rekindled the torch of public discord. The Queen-Regent had also lately been much incensed against the Prince de Condé, who had shown himself wanting in respect and deference to her Majesty; and petty intrigues of all kinds were at work against him. On the 18th of January 1650, as the Princes of Condé, Conti, and the Duc de Longueville entered the Royal Council-chamber, they were arrested, and sent off without a moment’s delay to the Château de Vincennes. This step caused a panic among their friends, who dispersed in all directions. The Duchesse de Longueville left Paris by night with a large escort, headed by her adorer, the Duc de la Rochefoucauld, and repaired to Normandy, to raise the inhabitants of the province against the King, in which undertaking, however, she was unsuccessful. Turenne took his way to Stenai, a stronghold belonging to the Prince de Condé, and openly avowed his indignation at the imprisonment of the Princes.
