Siege of Mantua (1632–1633)

Timeline

1. 1632Duchy of Milan and the Mantua area · Duchy of MilanThe 1631 Treaty of Cherasco nominally ended the War of the Mantuan Succession, with the French-backed Charles Gonzaga gaining the ducal titles of Mantua and Montferrat. However, the Spanish governor of Milan, dissatisfied with the treaty's outcome, began regathering forces in the Duchy of Milan from 1632, applying military pressure around Mantua and cutting some grain and supply routes.
2. 1632–1633Mantua · Duchy of MantuaSpanish forces imposed a partial blockade on the Mantua fortress, restricting traffic in and out, and sought to exhaust the resources of the new duke of Mantua through fortress warfare. Duke Charles Gonzaga of Mantua appealed to France, but the French government under Richelieu was pressed on multiple fronts and relief was slow. The Mantua garrison, relying on lake and waterway fortifications, contended with the Spanish.
3. 1633Mantua and northern Italy · LombardyAs the situation shifted on the main German front of the Thirty Years' War, Spain concentrated more resources on the northern European theater, and military pressure in Italy eased. The siege of Mantua gradually relaxed, but geopolitical tensions in northern Italy were not resolved, laying the groundwork for continued Franco-Spanish conflict on the Italian front.
