Dutch Captain: Gerrit Klaeszoon Posthoorn

At the beginning of the Second Anglo-Dutch War, Gerrit Klaeszoon Posthoorn served the Middelburg Chamber of the VOC. He commanded the VOC warship Agatha (32 guns and a crew of 105 men) and fought in the Battle of Lowestoft, where he was assigned to Volckert Schramm's Seventh Squadron. He still commanded the Agatha with De Ruyter's fleet in August 1665. Volckert Schramm's squadron was composed mostly of ships belonging to the Admiralty of the Noorderkwartier. After 1665, the VOC ships were removed from the fleet. Gerrit Klaeszoon Posthoorn fought in the St. James's Day Battle, where he commanded a Noorderkwartier frigate, the Wapen van Hoorn (30 guns and a crew of 150 men) in Cornelis Tromp's squadron. By 1670, he was back in the VOC service, this time for the Hoorn Chamber of the VOC. He made a voyage to the East Indies in 1670 on the ship Gekroonde Vrede". Sources:
