The Dutch, who were in an alliance with the Kingdom of Kandy, landed an expeditionary force under Commodore Willem Jacobszoon Coster of Akersloot, at the Bay of Galle, on 8 March 1640. After bombarding the fort for four consecutive days, Dutch troops stormed the fort and secured a victory on 13 March 1640. The Portuguese garrison, led by Captain Lourenço Ferreira de Brito, mounted a stiff resistance and unexpectedly high casualty rates among Dutch troops gave rise to the proverb “Gold in Malacca, lead in Galle”. With this victory the Dutch gained access to a large port which they later used as a convenient naval base to attack Goa and other South Indian Portuguese defenses. They also gained access to the Sri Lankan cinnamon trade and gained a permanent foothold on the island.

In 1638 the war restarted when the Dutch East India Company intervened in the conflict, initially as an ally of the Sinhalese against the Portuguese, but later as an enemy of both sides. The war concluded in 1658, with the Dutch in control of about half the island, the Kingdom of Kandy the other half, and the Portuguese expelled.
