By 1651 the Anglo-Dutch Wars erupted in Europe, which subsequently affected Batavian relations with English trading interests in Banten. The war reflected with the fierce trading competitions and clashes between Dutch East India Company and British East India Company. Dutch Batavia once again imposed a blockade upon Banten, since the port was the center of British trading interest in the archipelago. This time however, Banten was quite powerful enough to resist Batavian coercion, albeit not on equal footing. Banten adopted rather indirect guerilla warfare, attacking Dutch ships on the high seas by sending fireships, also launching raids and harassing farmlands around Batavia.
