Why am I writing about the First Anglo-Dutch War? The reason is that is where I have done my research, and where a great deal remains to be done. Frank Fox has the definitive work on the Second Anglo-Dutch War, his book A Distant Storm: the four days battle of 1666. As for the Third Anglo-Dutch War, there is no definitive work. There are a number of useful works, but there is still room for more research and and writing. From the Dutch perspective, the First Anglo-Dutch War either continued or ended the careers of officers who had figured prominently in period from 1628, or earlier, to 1648. The greatest event of the era was the Battle of the Downs, when the Dutch fleet, under the command of Marten Tromp, decimated the Spanish armada, in English coastal waters. One example of such an officer was Cornelis Engelen Silvergieter, who at the beginning of the first war, commanded the 22-gun Rotterdam Admiralty ship, the Overijssel. By late in 1652, Dirck Vijch took over command from him. In 1628 and 1628, Captain Silvergieter had commanded the 170-last warship, the Zeekalf. There are some obvious examples of careers beginning in the First Anglo-Dutch War, or shortly before. The most prominent was Cornelis Tromp (1629-1691), son of Marten. Another example was Jan van Nes, the Jonge Boer Jaep (1631-1680). In February, 1652, he commanded the frigate Gelderland.
