There are still many questions to be resolved about Dutch ships and captains in the First Anglo-Dutch War

We still have many unresolved questions about Dutch ships and captains during the First Anglo-Dutch War. We have filled in some gaps in the last 3 years, including in the last 6 months, but many remain. One question, still, is if Bastiaan Centen took command of the Haas in 't Veld from Leendert den Haen, or if the Haes that he commanded was a different ship. The ship that he commanded had been hired by the Vlissingen Directors. He apparently commanded her in the Battle of Dungeness, and probably, beyond that date. He fought in the Battle of Portland, as he was with the 17 ships that went to Vlissingen after the battle. We also know that he fought in the Battle of Scheveningen, where he was assigned to Frans Mangelaer's small unit (certainly not a "squadron"). He was assigned to De Ruyter's squadron. Sources:
