I have had a number of open questions that I had not been able to resolve, in my research about the First Anglo-Dutch War:
The first seems clearer, at this point. There is overwhelming evidence that Claes Janszoon Sanger became an English prisoner, after the Battle of Scheveningen and that his ship was burnt. The fact that the West Cappelle was listed in the "Staet van Oorlogh te Water voor den Jaere 1654" is simply a records keeping issue. That there was a West Cappel in service later is likely explained by a new ship having been built. We don't know that for sure, from what we have seen to date, but it seems likely.
The question of Sipke Fockes, the Sint Maria, the Groot Sint Lucas are still hard to finally resolve. There is the following pieces of evidence:
I have been resistent to concluding that there really was another ship named Groote St. Lucas that has not otherwise been noted in any published sources, or in any records found, to date. I am starting to think that it might be the case, however.
As an afterthought, I need to examine the section on the Battle of Portland, in the Onstelde-Zee, as there are at least three Dutch ships mentioned there that need further research:
