William Penn said that they had taken a "Wapen van Medemblick" at the Kentish Knock

William Penn wrote of taking a ship that he called the Arms of Medemblick (Wapen van Medemblick) at the Kentish Knock. He said that he recommended Captain Norman to command her in the English service. That seems pretty solid, although it is impossible to correlate that to what we know from the Dutch side. For example, the only losses mentioned were the Maria, Claes Sael's ship, captured, and the Burg van Alkmaar, Gerrit Nobel's ship, sunk. John Mildmay wrote of having three Dutch captains on board his ship, including Jan Jacobszoon van Nes, apparently, who commanded the Rotterdam ship Gorcum. Apparently, the Gorcum had been badly shot up, and John Mildmay had takeon off captain and crew, expecting the Gorcum to sink. Sources:
