Dutch Captain: J. Kuijper

Captain J. Kuijper served the Admiralty of Amsterdam. He commanded the Agatha (50 guns) in the fleet that took Willem III to England. At the Battle of Beachy Head, he commanded the Castricum (50 guns) in the Van Squadron commanded by Cornelis Evertsen. Oddly enough, he is not listed in the index for De Jonge's book, despite being present in at least one list. Sources:
