Henri de Montmorency, 4th Duke of Montmorency

Henri de Montmorency, 4th Duke of Montmorency was a French military officer. Made Grand Amiral in 1612, governor of Languedoc in 1614, and by 1620 was viceroy of New France. Despite defeating a Protestant fleet and seizing islands of Ré and Oléron, Cardinal Richelieu kept him from taking advantage of these victories. Henri defeated the Duke of Rohan in Languedoc during 1628-1629. He gained notoriety as a military commander in Piedmont during the War of the Mantuan Succession in 1630. Joining the forces of Gaston, Duke of Orleans, Henri raised an army and was severely wounded at Battle of Castelnaudary. Captured, he was executed on 30 October 1632, by a guillotine-like device.
