Returning after Richelieu's death in 1643, he entered into the intrigues of the period just preceding the Fronde. He was exiled for his involvement in the "" in 1643. He later returned from the safety of his exile in Holland to aid the duchesse de Chevreuse. He allied with the cardinal de Retz during the Fronde, and was eventually imprisoned in the Bastille, and then in Vincennes. Mazarin attempted to win him over in vain, but in 1653 he made his submission to the victorious minister, and from that time on played no part in public life.
