I have made some more progress on developing the orders of battle for the Gabbard. The English side is quite straight-forward, as the widely published list seems to be accurate.
The Dutch order of battle is quite difficult, as there are probably more than a dozen ships that we don't know their names. There are a few ships that we know the name and captain, but don't know anything else. I have previously mentioned Jan Glete's notes that show a list, from early 1652, that indicates that there were some Directors' ships with names like "Colburg" and "Harderwijk". I have not been able to find that document (in the Nationaal Archief, in the Hague), and really need to find it. I also desperately need a copy of Hendrick de Raedt's pamphlet that lists Tromp's fleet during his disastrous voyage to the Shetlands, in July-August 1652.
