Claes Jansz Sanger in early August 1653

One curiosity that I noticed today, in a page that I received, is that the list shows Claes Jansz Sanger, on 1 August 1653, as captain of the ship Milde Maerten. That is curious because there is every reason to believe that on 10 August, he was captain of the Zeeland ship Westcappel, when it was lost in the Battle of Scheveningen. Presumably, this is just because a feature of documents from the First Anglo-Dutch War is that they are often mistaken, or at least have errors introduced by copyists.
