Dutch Captain: Hendrik Vroom

Hendrik Vroom served the Admiralty of Amsterdam. He commanded the Huis Tijdverdrijf (60 guns) in De Ruyter's fleet in August 1665. He fought in the Four Days' Battle, where he commanded the Wakende Boei (46 guns). He was assigned to Cornelis Evertsen's squadron in that battle. He also fought in the St. James's Day Battle (the Two Days Battle) in August 1666. He again commanded the Wakende Boei and was assigned to Jan Evertsen's squadron. As best as I can tell from Brandt, Hendrik Vroom was killed in the St. James's Day Battle. Sources:
