Lambert Bartelszoon's ship in 1652 and 1653

Lambert Bartelszoon commanded a ship named Eendracht that had been hired by the Admiralty of Zeeland in 1652. He spent much of the First Anglo-Dutch War with the main Dutch battlefleet, except for period during mid-1653, when he was engaged in warfare against English commerce. For a long time, when I saw the listing for his ship, with 18 guns and a crew of 100 men, I assumed that the 18 was a typographical error for 28. But no, that was not the case. He did command a lightly-armed frigate that would have been suitable as a scout. His ship was one of the 100 ships to be hired by the admiralties in 1652.
