Michiel De Ruyter's squadron at Scheveningen (amended)

As I am working on building Dutch OOB's for the Gabbard and Scheveningen, I have been reading through the published sources. I believe that I missed one ship that was in De Ruyter's division within his squadron. I will try to format the information better, this time.

De Ruijter apparently flew his flag on the Witte Lam, at both the Battle of the Gabbard and Scheveningen. I remember seeing, in Salt in Their Blood, that the Lam had 40 guns and a crew of 145 men. In the published list from 1652, near the beginning of the war, Jan Tijssen's ship only carried 32 guns and had a crew of 110 men. We know the composition of his squadron at Scheveningen by the orders he gave to the individual captains.  These are documented in The First Dutch War, Vol.V. Asterisks (*) denote estimates. The ships are in the order that they are mentioned, except that we include De Ruyter's ship.

Captain/Admiral	"Admiralty"	Ship
Michiel De Ruyter	Vlissingen Directors	Witte Lam, 40 guns
Dingeman Cats	Zeeland	Gekroonde Liefde, 23 guns
Hendrick Kroeger	Amsterdam	Leiden, 28 guns
Lt-Commander Anthonis Fappenlain (or Anthonis Foppenthey), Lieutenant of Tijs Tijmenszoon Peereboom	Noorderkwartier	Peereboom, 24 guns
Jan Olivierszoon	Veere Directors	Unknown ship, 38 guns
Gillis Janszoon	Zeeland	Zeeridder, 28 guns
Adriaan Corneliszoon van Ackersloot	Amsterdam Directors	Moor, 34 guns
Frans Mangelaar	Zeeland	Liefde, 30 guns
Evert Pieterszoon Swart	Amsterdam Chamber of the VOC	Gerechtigheid
Bastiaan Centen (Senten or Centsen)	Zeeland	Haes
Jan Pieterszoon Strijp	Amsterdam Chamber of the VOC	Huis van Nassau
Markus Hartman	Zeeland	Gekroonde Liefde, 34 guns
Jakob Wolfertszoon	Zeeland	Unknown ship, 28 guns*
Jakob Swart (possibly Jacob Cornelisz. Swart)	Amsterdam Directors	Faam, 28 guns
Pieter de Bitter	Amsterdam Chamber of the VOC	Mercurius, 36 guns*

That would give De Ruijter's squadron a strength of 15 ships, which is plausible., although I would have guessed his squadron to be larger.
