A list dating from 6 December 1652 shows that Crijn Cornelisz Mangelaer commanded the Wapen van Zierickzee

I have a list of captains, groups by admiralty or directors, that shows that Crijn Cornelisz Mangelaer commanded the Zierickzee Directors' ship Wapen van Zierickzee on 6 December 1652. That assures that he commanded the ship in the Battle of Dungeness on 10 December. The Wapen van Zierickzee carried 34 guns and had been commanded by Cornelis Rocusz Fincen up until later in the year. Sources:
