You will be of great service to England, 1943-1945. The odyssey of Jacques de Duve.
After two unsuccessful escape attempts at the beginning of the Second World War, Jacques de Duve, Belgian patriot stemming from an old German family from Hannover is more than ever keen to be of service for his country and to join his English wife, a close collaborator of Paul-Henri Spaak in London.
To do so, he will follow the advice of two German officers opposed to the Nazi regime: his paternal uncle who works for Organisation Todt and one of his long-time friends, in charge of the “Abwehr” in Antwerp. De Duve gets himself enrolled in the Abwehr for the sole purpose of sending military intelligence of the highest order to the Allies as soon as possible. His reception in England turned out not to be what he had expected. After his incredible escape, he was imprisoned in a secret MI5 prison under harsh conditions. For one year, the English services would insist on depicting him as a German secret service agent... When he returned to Belgium, he was entirely cleared of all accusations and awarded the Croix des évadés.
In order to retrace the captivating and touching odyssey of his father-in-law and to write the book ‘Tu rendras un grand service à l’Angleterre, 1943-1945. L’odyssée de Jacques de Duve’ (You will be of great service to England, 1943-1945. The odyssey of Jacques de Duve), Charles-Albert de Behault collected and studied many documents held by his family as well as publicly available sources.
The conference-debate took place at CegeSoma on May 24, 2023. Charles-Albert de Behault was interviewed by Fabrice Maerten.

Charles-Albert de Behault holds a diploma in law, finance and management. Since his retirement, he has published a dozen of historical papers. His work is mainly based on primary sources.
“Tu rendras un grand service à l’Angleterre”, his first book, is the product of three years of research in many files for the most part recently declassified or still with restricted access. Claus Taaks, German historian specialised in Enigma (cipher device) and the German resistance to Nazism has helped him in this task.
