Rittmeister Kurt Mirow from Ast Brussels went to Holland to recruit spies. After having found three spies in Amsterdam, he traveled to The Hague and Noordwijk aan Zee around 25 July. In Noordwijk he had a good relation: Dieter Tappenbeck (1912), who was a cousin of Rudolf Tappenbeck, the director of the famous Grand Hotel Huis ter Duin. Dieter was a brilliant young man, he had studied geology, had worked for the Dutch Press Office, was a real Nazi and worked at that time for one of the German Ministries in Berlin. But in July/August he was back in the Netherlands for propaganda work in the Reichskommissariat of Seyss Inquart in The Hague.
