 Anthonie Sailly, an agent of the States-General of the Netherlands at Calais, informed the Dutch government regarding the attacks by the privateering expedition and, by 16 August, two fleets began to be organized to locate and take action against the privateers while all available vessels in Rotterdam were sent out in search of them.The seven remaining privateers eventually encountered one of these Dutch fleets sent out against them, near the island of Vlieland, commanded by Captain Arie Corneliszoon Cruyck.The privateers fled from Cruyck's force reportedly dumping as much cargo overboard as possible in an attempt to outrun the Dutch naval fleet.
