The Blockade of La Rochelle (French: Blocus de La Rochelle) took place in 1621-1622 during the repression of the Huguenot rebellion by the French king Louis XIII. In June 1621, Louis XIII besieged and captured Saint-Jean d'Angély, a strategic city controlling the approaches to the Huguenot stronghold of La Rochelle. Louis XIII chose however to move south with his main force for the Siege of Montauban.
