Dutch Captain: Cornelis Janszoon Poort

De Sleutels van de Sont also lists Cornelis Janszoon Poort as commanding a ship belonging to the New Directors of Amsterdam. In 1645, he commanded the Patientia (26 guns and a crew of 71 men). Cornelis Janszoon Poort commanded an Amsterdam Directors ship Kroon Imperiaal (34 guns) in 1652 and up until the Battle of Portland in 1653, when he was apparently killed and his ship was sunk. We have to wonder if the Patientia was the same ship hired by the Admiralty of Amsterdam in 1652 and commanded by Adriaan van Loenen. In 1652, the Patientia was armed with 24 guns and had a crew of 80 men. Sources:
