Ferdinand von Spanien
The siege of Venlo was an important siege in the Eighty Years' War that lasted from 20 to 25 August 1637. The Cardinal-Infante Ferdinand of Austria, Governor of the Spanish Netherlands, retook the city of Venlo from the United Provinces, which had taken control of it in 1632 during the offensive of Frederick Henry, Prince of Orange against Maastricht. The capture of Venlo and Roermond, which was surrendered to the Cardinal-Infante a week later, effectively cut Maastricht from the Dutch Republic, thus preventing further attacks on the Spanish Netherlands from the east. In the southern front Ferdinand lost the towns of La Capelle, Landrecies, and Damvillers to the French, but then he forced them to retreat south of Maubeuge.
