 The surrender of the English when attacked by several Dutch fireships after it had run aground because of the panic this attack caused only demonstrated that fireships were useful against warships that were stationary or in confined harbours, but not those able to move in the open sea.However, this overall lack of success in this battle did not prevent both sides adding more fireships to their fleets.Second Anglo-Dutch War arose from an escalation of existing commercial tensions between England and the Netherlands in 1664, involving English provocations in North America and West Africa.
