 Louis de Marillac was Gentleman in ordinary of the Bedchamber to Henri IV, and greatly distinguished himself by his valour alike under that sovereign and his successor Louis XIII. He was created Marshal of France in 1629; and was arrested in the camp of Felizzo, in Piedmont, in 1632, for having, as was asserted, volunteered to assassinate Richelieu with his own hand, when he voted against him in the assembly known as the “Day of Dupes.” On the 8th of May in the same year he was condemned to lose his head; a sentence which was carried into execution in the Place de Greve; but his character was subsequently vindicated by a decree of the Parliament after the death of the Cardinal.
