The Siege of Salvador da Bahia was a siege that took place between April and May 1638, during the Dutch–Portuguese War and Eighty Years' War. The governor of the Dutch colony in Brazil, John Maurice, Prince of Nassau-Siegen, commanding the army of the Dutch West India Company, with vastly superior forces and a supporting fleet under Johan van der Mast, put the city of Salvador da Bahia under siege. The Portuguese and Spanish defenders, commanded by Giovanni di San Felice, Count of Bagnolo, and Luís Barbalho, managed to resist the Dutch attacks until they gave up taking the city and withdrew with several casualties.[7]
