Meanwhile, the party in opposition to Mazarin became divided into the new and old Fronde. No one could tell to which De Retz would adhere long. He, for the moment, headed the old, the prince of Condé the new. Rochefoucauld hated De Retz, we are told, with a hatred seldom felt, except by rival men of talent.[25] He now, therefore, sided with Condé, and endeavoured to alienate him entirely from the coadjutor, and to draw over his brother and sister to the same side. He entered zealously into the plan of breaking off a marriage proposed between the prince of Conti and mademoiselle de Chevreuse, who was known to be the mistress of De Retz, which event widened the separation between the parties. This led to more violent scenes than ever. Condé was forced to retreat, and only appeared strongly guarded; and the queen took advantage of this show of violence to accuse him of high treason to parliament. This occasioned the most tumultuous scenes. The two parties met in the Palace of Justice; both Condé and De Retz surrounded by followers eager to draw their swords on each other,--none more eager than Rochefoucauld, whom De Retz detested, and (if we believe the duke's own account) had several times sought to have assassinated. On this occasion Rochefoucauld was on the alert to revenge himself. Molé, the intrepid and courageous president, alone, by his resolution and firmness, prevented bloodshed. He implored the prince and the coadjutor to withdraw their troops from the palace: they assented. De Retz left the hall to command his followers to retire. Rochefoucauld was sent by Condé on a similar mission to his partisans. This was a more difficult task than they had apprehended: both parties were on the point of coming to blows; and the coadjutor hastened to return to the great chamber, when an extraordinary scene, related by the duke in his memoirs, ensued. He had returned before the coadjutor, and De Retz, pushing the door open, got half in, when Rochefoucauld pressed against it on the other side, and held his enemy's body in the doorway, half in and half out of the chamber. "This opportunity might have tempted the duke de la Rochefoucauld," writes the duke himself. "After all that had passed, both public and private reasons led him to desire to destroy his most mortal enemy; as, besides the facility thus offered of revenging himself, while he avenged the prince for the shame and disgrace he had endured, he saw also that the life of the coadjutor ought to answer for the disorder he occasioned. But, on the other side, he considered that no combat had been begun; that no one came against him to defend the coadjutor; that he had not the same pretext for attacking him as if blows had already been interchanged--the followers of the prince, also, who were near the duke, did not reflect on the extent of the service they might have rendered their master in this conjuncture;--in fine, the duke would not commit an
