Henri, Duc de, peer of France, and prince of Leon, was born at the Chateau de Blein, in Brittany, in 1579. Henri IV., under whose eye he gave distinguished proofs of his bravery at the siege of Amiens, when only sixteen years of age, loved him with as much affection as if he had been his own son. After the death of Henry, he became chief of the Calvinists in France; and was equally formidable for his genius as for his sword. In defense of the civil and religious rights of his party, he maintained three wars against Louis XIII. The first, which terminated to the advantage of the Protestants, broke out when that prince wished to establish the Romish religion in Bearn; the second, because of the siege which Cardinal de Richelieu ordered to be laid to Rochelle; and the third, when that place was besieged a second time. The consequences of this war are sufficiently known: Rochelle surrendered, and the Duc de Rohan, perceiving that, after the taking of this place, the majority of his party were endeavouring to make up matters with the court, succeeded in procuring for them a general peace in 1629, upon very honourable and advantageous terms. There is an anecdote told of him, in the *Memoirs of the Duchess of Rohan*, Mar- garet of Bethune, daughter of the famous Sully. While the Duke de Rohan was at Venice, a proposal was made to him from the Porte, that for 200,000 crowns, and an annual tribute of 60,000 livres, the grand seignior would give him the island of Cyprus, and fully invest him with the dignity and prerogative of king. The duke was warmly inclined to comply with this proposal, and to settle in the island the Protestant families of France and Germany. He negotiated this business at the Porte by means of the intervention of the patriarch Cyril, with whom he had much correspondence; but different circumstances, and in particular the death of the patriarch, contributed to break off the treaty. The republic of Venice chose Rohan for their commander-in-chief against the imperialists; but Louis XIII. took him from the Venetians, and sent him ambassador into Switzerland and into the Grisons. He wished to assist these people in reducing La Valteline to obedience, the revolt of which the Spaniards and imperialists encouraged. Rohan being declared general of the Grisons, after many victories, drove the German and Spanish troops entirely from La Valteline in 1633. He again defeated the Spaniards in 1636, at the banks of the Lake of Como. France, not thinking it proper to withdraw her troops, the Grisons rose up in arms; and the Duke de Rohan, not satisfied with the conduct of the court, entered into a special treaty with them on the 28th of March 1637. This hero, fearing the resentment of Cardinal de Richelieu, retired to Geneva, with a view of joining his friend the Duke of Saxe-Weimar, who wished him to undertake the command of his army, then ready to engage the imperialists near Rhinefeldt. Although he declined this honour, yet he took the command of the regiment of Nassau, with which he threw the enemy into confusion; but was himself wounded, 28th February 1638, and died the 13th of April following, at the age of fifty-nine. He wrote several interesting performances:

Les Intérêts des Princes, printed at Cologne in 1666, in 12mo. Le parfait Capitaine, or an abridgment of the wars from Caesar's Commentaries, in 12mo. Traité de la Corruption de la Milice Ancienne; Traité de Gouvernement des 13 Cantons; also Mémoires. They contain the history of France from 1610 to 1629. Recueil de quelques Discours Politiques sur les Affaires d'Etat, from 1612 to 1629, 8vo, Paris, 1644, 1653, 1755; with Mémoires et Lettres de Henri, Duke de Rohan, sur la Guerre de la Valletine, 3 vols. 12mo, Geneva, 1757. This was the first edition which appeared of these curious memoirs: we owe it to the great attention and diligence of Baron de Zurlauben, who published them from different authentic manuscripts, with a highly interesting Life of the noble author.
