Dutch Captain: Jacob van Berchem
Jacob van Berchem served the Admiralty of Amsterdam. Sadly, I do not have much information about him. We know that he served in De Ruyter's fleet sent to the Sound in 1659-1660. In that fleet, he commanded the Tromp (or Muiltromp). The Tromp was built in 1655 at Amsterdam, probably in the continuation of the First Anglo-Dutch War building program. In 1659, the Tromp carried 40 guns and had a crew of 190 men. Her dimensions were 130ft x 32ft x 13-1/2ft. Sources:
