Dutch Captain: Johan Belgicus, graaf van Hoorne

Johan Belgicus, graaf van Hoorne, served the Admiralty of the Noorderkwartier. He had been a midshipman in 1663 and a captain in 1666. In 1664, he had served under De Ruyter in the Mediterranean Sea and on the Guinea coast. In 1666, he commanded the Gelderland in the Four Days' Battle and the St. James's Day Battle. In 1672, he fought in the Battle of Solebay, where he commanded the Westfriesland (78 guns). Later in 1672 until 1673, he served as a lieutenant-colonel of Marines on "the waterline". In 1674, he served under De Ruyter on the expedition to Martinique. He must have been serving as a marine or soldier, as he did not command a ship. Sources:
