I was interested to find this about Vice-Admiral van Foreest

When the Germans attacked the Netherlands in 1940, Lt-Cdr van Foreest was executive officer of the incomplete cruiser Jacob van Heemskerck. the ship had its propulsion plant installed, so Lt-Cdr van Foreest commissioned the ship and got underway from Amsterdam. He took the ship to Great Britain, where the ship was completed and fought in the war. Presumably, this is the co-author of Dr. Weber's book about the Four Days' Battle.
