Robert Alesch

Alesch was sentenced to death and held in Fresnes prison before being executed by firing squad on 25 January 1949 at Fort de Montrouge [fr] in Arcueil.

After the war, Alesch fled to Brussels. He was handed over to the French authorities and tried by the Court of Justice (order of June 26, 1944) [fr] of the Seine department. The surviving members of the network, Tillion (who invoked the memory of her mother Émilie Tillion, murdered at Ravensbrück), Picabia and Pierre Weydert were also there to witness at the trial. Former Abwehr colleague, Hugo Bleicher, also testified against him.

Alesch was paid for his information by the Germans and lived a double life. Priest during the day, he lived with two mistresses on rue Spontini in the 16th arrondissement. On 13 August 1942, Legrand, Tillion and the main leaders of the network were arrested. Around 80 people found themselves imprisoned over the month of August. Detained in Fresnes prison and Prison de la Santé, they were subjected to long interrogations and in some cases, torture, by the German police. After being moved to the camp at Fort de Romainville they were mostly deported to the concentration camps of Buchenwald, Mauthausen and Ravensbrück. Jacques Legrand, his second, Thomasson and a number of others did not return from deportation.

His victims also included Virginia Hall, an American-born agent of the British intelligence service SOE. After worming his way into her confidence, Alesch discovered her section's activities in unoccupied southern France. In May 1942, as organiser of the Heckler circuit in Lyon, Hall agreed to have messages from the Gloria Network to be transmitted to SOE in London. Alesch infiltrated Gloria in August leading to its leadership being captured by the Abwehr. Alesch then made contact with Hall claiming to be an agent of Gloria and offering intelligence of apparently high value. She had doubts about Alesch, especially when she learned that Gloria had been destroyed, but was persuaded of his bona fides, as was the London headquarters of SOE. Alesch was able to penetrate Hall's network of contacts, including the capture of wireless operators and the sending of false messages to London in her name. Many of those captured did not survive.

Alesch relocated to Freiburg to study theology and was ordained in 1933 and settled in France in 1935. He was named vicar at La Varenne-Saint-Hilaire, parish of Saint-Maur, in the Paris region. From the beginning of the Nazi occupation, he passed himself off as an opponent of the Germans, particularly during his Sunday sermons. He saw the Occupation, however, as an opportunity to earn money and offered his service to the Gestapo in 1941.

Robert Alesch (6 March 1906 – 25 January 1949) was a Catholic priest and collaborator with Nazi Germany during the Second World War.

Alesch was born 6 March 1906 in Aspelt, Luxembourg. He claimed that his father was a Lorraine French patriot, who was tortured by the Germans in 1917.
