The Battle of the Kentish Knock

Dr. Elias's book Schetsen uit de Geschiedenis van ons Zeewezen, in Vol.V, has some very good references about ships and the fleet. In Vol.III, for the Battle of the Kentish Knock, that is strangely absent. He mostly refers to The First Dutch War, Vol.II, Brandt's biography of De Ruyter, and the Hollandsche Mercurius. He does refer to Witte de With's journal and to some references in the Staten Generaal, but he seemed to lack knowledge of where the good information was located. For that matter, that is true for me, as well. I happen to know that at least some "good information" exists and that it is a matter of finding where it is. The reason being that it is so good, that there is some advantage for the researcher and author who knows where it is, when there is good reason to want to be the first to publish it.
