In the four naval battles of the Third Anglo-Dutch War Banckert played an important role, especially by fighting the French squadron within the combined Anglo-French fleet. At the Battle of Solebay Banckert managed to lure away the French fleet allowing the main Dutch force under Lieutenant-Admiral Michiel de Ruyter to attack the English fleet with some parity. In the first action of the double Battle of Schooneveld the French fleet broke formation to attack Banckert's squadron, which allowed Lieutenant-Admiral-General De Ruyter to split the French squadron and outmanoeuvre the allies. In the second action Banckert's attack drove the French away. In the Battle of Texel Banckert managed to prevent a joining of the French and English fleet, again allowing De Ruyter to fight the English with more equal forces. Because of the crucial part he played in these battles Banckert's fame among the French and English was assured; ironically in The Netherlands his importance wasn't understood by the larger part of the population, also because most writers were Hollandic and felt little inclination to honour a Zealandic hero.
