From the latest finds, there is no assurance for a particular date, who commanded a Dutch warship

From Carl Stapel's latest finds, I would say that there is no assurance as to which ship a particular captain commanded. You actually have to see a contemporary, handwritten document to be relatively assured about who commanded which ship. Also, the published lists omit many ships, so we find. After what I have seen over the last four years, I had figured this out, but Ron van Maanen's list just reinforced that impression, as he listed many ships that I had never seen mentioned before. For example, who knew that Pieter Gorcum's ship, in the First Anglo-Dutch War, was the Sandenburgh?
