The ships in the Fishery Protection Squadron in 1652 are still something of a mystery

The Hollandsche Mercurius and The First Dutch War, Vol.I, both have the list of ships in the Fishery Protection Squadron that was attacked and eliminated on 22 July 1652. I still am not totally convinced that the list published is accurate. There is reason to believe that the squadron consisted of 15 or 16 ships. There are still many ships in the squadron which have not been found in archival documents. Enough have been found to indicate that the list may, in fact, be accurate, as it is given. We already know that the Marcus Curtius was also taken on 22 July, but is not in those other lists. There are several ships that we have complete information about, including the Marcus Curtius, the Juffrouw Catharina, and the Kalmar Sleutel. The last is from Ron van Maanen's lists, while the others are in the list of Amsterdam ships hired, from the Wrangell Collection. Sources:
