There is more to be learned and understood

There is more information that has been found that indicates that our understanding of Dutch captains and warships for March to September 1652 (and probably more than that) is still incomplete. For example, there were two Amsterdam ships named Overijssel in service at the start of 1652. One was the new ship Overijssel, built in 1650 (seemingly) and the other was an older ship that may or may not have served in the Battle of the Downs in 1639. I have seen a list from 30 June 1652 that indicated that Jan van Campen served with the fleet on that date. What ship did he command? On 5 August 1652, he and Dirck Schey were fitting out two ships between Amsterdam and the Texel. Dirck Schey's ship was the Achillis (the 131ft long ship) while Jan van Campen's ship seems to have been the newer Overijssel. That must mean that the older Overijssel was not sold in March but was still in service, under the command of Abraham van der Hulst.
