In 1666, he commanded the Delft (34 guns) and the Vlissingen (50 guns) in the Four Days Battle and the St. James Day Battle (The Two Days Battle). In 1667, he was at the raid on Chatham. In 1672, he was a Schout-bij-Nacht at the battle of Solebay. I would like to include an HTML table, but they don't seem to work very well in Blogger. For many of the Dutch captains and admirals, I have entries, by year, about ships they commanded.
