A page dated 28 July 1653 with notes at the bottom

A letter signed by "M.Harperts Tromp", dated 28 July 1653, has some interesting notes at the bottom. The notes titled "Of Zeeland" caught my eye:

Vice-Adm. Jan Evertsz.
the English prize captured (perhaps the Bonaventura)
van der Veer (perhaps the Wapen van der Veere)
the ship Nieuw Vlissingen
the Salamander

These were all ships that fought in the Battle of Scheveningen (or Ter Heide) on 10 August 1653.
