Dutch–Portuguese War

The Battle of Swally was a naval engagement fought off the coast of Suvali, near Surat, in which four English East India Company galleons defeated four Portuguese galleons and 26 barks. The engagement took place within the context of the broader Dutch–Portuguese War and the intensifying competition among European powers for control of Indian Ocean trade. An English victory over a substantially larger Portuguese flotilla in these waters carried direct commercial and strategic implications for access to Surat, one of the principal ports of Mughal India and a critical node in the spice and textile trades. Portuguese dominance in the region had long shaped the terms on which other European powers could operate along the Indian coast, and a defeat of this scale by English Company forces signaled a shift in that balance. The inputs available do not record the full outcome or its precise consequences, but the engagement is consistent with the pattern of English encroachment on Portuguese maritime primacy in the early seventeenth century.

The Battle of Macau in 1622 was an engagement of the Dutch–Portuguese War fought within the Portuguese settlement of Macau in southeastern China. Despite being outnumbered and lacking adequate fortification, Portuguese forces under Lopo Sarmento de Carvalho repelled the Dutch East India Company expedition commanded by Cornelis Reijersen and Hans Ruffijn over the course of a three-day battle. The victory was much celebrated by the Portuguese and secured their continued hold on Macau, a strategically and commercially significant outpost on the Chinese mainland. The battle holds a distinctive place in the history of the Dutch–Portuguese War as the only major engagement fought primarily between two European powers on the Chinese mainland, setting it apart from the broader contest for colonial trade routes and maritime dominance that characterized the wider conflict.

The Battle of Elmina on 25 October 1625 was an engagement in the Dutch–Portuguese War in which forces of the Dutch West India Company, numbering 1,200 and commanded by Jan Dircksz Lam, confronted a Portuguese force under Fernando de Sottomayor. Elmina, on the West African coast, was a strategically significant Portuguese trading post, and Dutch efforts against it reflect the broader Dutch West India Company campaign to displace Portuguese commercial and colonial power in West Africa during this period of the wider conflict. No recorded outcome, casualties, or further operational detail survive in the available record.

The Battle of Guararapes, fought on February 19, 1649, was an engagement between West India Company (WIC) forces and those of the Kingdom of Portugal during the Dutch–Portuguese War. The WIC fielded a numerically superior force of 3,500 against a Portuguese force of 2,600, yet sustained recorded casualties of 1,045. The Portuguese side was led by multiple commanders — Francisco Barreto, Filipe Camarão, Henrique Dias, and Vidal de Negreiros — against the WIC's Van Den Brinck. The scale of WIC losses relative to the size of the engagement points to a significant Portuguese battlefield success within the broader contest over Portuguese Brazil that defined this phase of the Dutch–Portuguese War.
