On Saterdag 14 November 2015 I attended the seminar of the Friends of the Airborne Museum at Oosterbeek in de Concert Hall Oosterbeek-Laag.

The young and enthousiastic new manager of the Airborne Museum arah Thurlings-Heijse introduced herself and told us about her plans for the future with the Airborne Museum.

On the left Sarah Thurlings-Heijse, directrice van het Airborne Museum, in the middle PR Natalie Rosenberg (public relations) on the right the former manager of the Airborne Museum Wybo Boersma.
During the break I carefully looked at the books and the collection of Wybo Boersma, which was dominated by Secret Warfare, Enigma and Bletchley Park.

There was another choice from a large collection of beautiful books. Many of the Battle of Arnhem, and the liberation of the Netherlands by the Canadians. The books' Canadians in action and Canadians purchased in the Netherlands from 1944 to 1945.
Not a book for reading from cover to cover if you are interested in Arnhem this book is a must. It details those men who were killed or lost their lives as a result of the fighting in September 1944. This 5th revised edition is the first in hardback and contains many more photographs - a must for any serious student of the battle. Since there is only a limited number available I was very glad that I could obtain this book.
 
After the break Gert Jan Vuyk gave a presentation of "Montgomery and the 2nd SS Panzerkorps". In his memoirs Montgomery dedicates the loss of Arnhem to the presence of the 2nd SS Panzer Corps. But gradually, during the presentation it became clear that this Panzerkorps was already a problem for the allies from July 1944 on and the plan Market Garden was hastily prepared and the Allies were well informed about the presence of the German division, thanks to the resistance, photo reconnaissance from the air and especially Enigma. Ultra posts from July '44 gave all information on this matter. Hailing from Bletchley Park. Where the Enigma codes were cracked.
This picture of the Enigma was shown. De Schlüsselmaschine E, also called Cypher Machine E, mainly well known as Enigma. Enigma is een generic name of In his memoirs Montgomery dedicates the loss of Arnhem to include the presence of the 2nd SS Panzer Corps. But gradually, the presentation was clear that this Panzerkorps often the Allies thwarted and that the plan Market Garden was hastily prepared and knew the Allies from the presence of the German division, thanks to the resistance, photo reconnaissance from the air and especially Enigma. Ultra posts from July '44 gave all information on this matter. Hailing from Bletchley Park.
On display was an Ultra message. The result of the cracking of a code message of Enigma.
Finally we watched a movie about Enigma and when I returned home I knew that it were not the British who started with cracking the code but the Polish, already in the 20s
