La Rochefoucauld's early education was neglected; his father, occupied in the affairs of state, either had not, or did not devote any time to his education. His natural talents and his habits of observation soon, however, supplied all deficiencies. By birth and station placed in the best society of the French Court, he soon became a most finished courtier. Knowing how precarious Court favour then was, his father, when young Rochefoucauld was only nine years old, sent him into the army. He was subsequently attached to the regiment of Auvergne. Though but sixteen he was present, and took part in the military operations at the siege of Cassel. The Court of Louis XIII. was then ruled imperiously by Richelieu. The Duke de la Rochefoucauld was strongly opposed to the Cardinal's party. By joining in the plots of Gaston of Orleans, he gave Richelieu an opportunity of ridding Paris of his opposition. When those plots were discovered, the Duke was sent into a sort of banishment to Blois. His son, who was then at Court with him, was, upon the pretext of a liaison with Mdlle. d'Hautefort, one of the ladies in waiting on the Queen (Anne of Austria), but in reality to prevent the Duke learning what was passing at Paris, sent with his father. The result of the exile was Rochefoucauld's marriage. With the exception that his wife's name was Mdlle. Vivonne, and that she was the mother of five sons and three daughters, nothing is known of her. While Rochefoucauld and his father were at Blois, the Duchesse de Chevreuse, one of the beauties of the Court, and the mistress of Louis, was banished to Tours. She and Rochefoucauld met, and soon became intimate, and for a time she was destined to be the one motive of his actions. The Duchesse was engaged in a correspondence with the Court of Spain and the Queen. Into this plot Rochefoucauld threw himself with all his energy; his connexion with the Queen brought him back to his old love Mdlle. d'Hautefort, and led him to her party, which he afterwards followed. The course he took shut him off from all chance of Court favour. The King regarded him with coldness, the Cardinal with irritation. Although the Bastile and the scaffold, the fate of Chalais and Montmorency, were before his eyes, they failed to deter him from plotting. He was about twenty-three; returning to Paris, he warmly sided with the Queen. He says in his Memoirs that the only persons she could then trust were himself and Mdlle. d'Hautefort, and it was proposed he should take both of them from Paris to Brussels. Into this plan he entered with all his youthful indiscretion, it being for several reasons the very one he would wish to adopt, as it would strengthen his influence with Anne of Austria, place Richelieu and his master in an uncomfortable position, and save Mdlle. d'Hautefort from the attentions the King was showing her.
