C. R. Boxer's book about Tromp's journal in 1639 has a reference to "Aitzema"

I noticed by chance that there is reference to Captain Waterdrincker's journal in "Aitzema" Vol.II, pp.613ff. I happen to own a copy, so I will follow up on this reference later in the day. It is referenced in a footnote on p.38 of Boxer's book. The gist of the note is that Tromp beat to windward towards the Spanish armada prior to heading towards Witte de With. Witte de With's journal paints Tromp as immediately fleeing the Spanish until De With halted his flight. There is an account of this action on September 16, 1639 that from the Spanish side by De Mello. The biography of De With, Leven en Bedrijf, was written by his son-in-law, Walter Bremen van der Hagen. It paints a dismal picture of Tromp that differs from what we believe to be true. This is all from Charles Boxer's book The Journal of Maarten Harpertszoon Tromp Anno 1639 (1930).
