There was apparently a lot of shuffling captains and ships in August 1652

Yet again, there are apparently surprises about which Dutch captain commanded which ship in early 1652. I do not have a good list of ships and captains for May to August 1652. I have better information dating from September, but there are still holes in my knowledge, even after having seen hundreds of pages from the Nationaal Archief in The Hague. I know just enough to know that I need to see better information about Amsterdam and Noorderkwartier ships, particularly. One thing that we know is that the Amsterdam ship Groningen was in service prior to September 1652, as you would expect.
