"Swarten Pieter"

A report from early March 1653 about the Three Days Battle says the commander of the Zeeland ship Faam was "Commandeur Swarten Pieter". He had commanded Cornelis Loncke's ship Faam in the battle. The report also names the dead captains, although Dirck Scheij would seem to have been in error. Also, Sipke Fockes was killed, but his ship was not captured (the Sint Maria).

Google Books

Google Books now has Gijs Rommelse's book about the Second Anglo-Dutch War as full view in the United States. You can't download it, but you can read it online. Also in the United States, they have Vol.II of William Laird Clowes' book The Royal Navy: A History.... Last night, I finally downloaded Vol.II of Granville Penn's biography of William Penn. I also downloaded quite a few volumes of a Dutch biographical dictionary: Biographisch woordenboek der Nederlanden.

It turns out that I have lists from 12 September 1653 that I need to use

I had missed the fact that I have two lists dated 12 September 1653 that I need to use in my analysis. They both include the ship Mars (38 guns), commanded by Reijnst Cornelisz Sevenhuijsen.

Thurloe's State Papers

The First Dutch War often has quotations from Thurloe's State Papers. The volumes are available online at British History Online.
