[1] During the war, Andre also coordinated activities in Belgium for the Office of Strategic Services, and his OSS contact Robert Solberg.

In Nazi Germany, his mentor as a secret agent was Colonel Rene Mampuys, who was the head of the Belgian army's intelligence service.

[3] When the Germans officially occupied Belgium, he, together with his comrade Fernand Canoot, founded a resistance group in the Ardennes under the name 'Athos'.

Under the aliases Capitaine Freddy, Le Crocodile, Cincinnatus and André de Saint-Michel, he carried out risky infiltration missions.

The Athos group organized a false "special police" which, without the Germans knowing, carried out operations to gather intelligence or to punish collaborators.

He became one of the most important Belgian counterspies and carried out missions in Congo, Morocco, Egypt, Taiwan, Vietnam and Korea.

[3] Bureau Milpol carried out financial intelligence missions in Belgium and had a network in the Belgian Congo.

[5] After 1945 he was a regular contributor or correspondent in Brussels for Europe-Amérique, Le Phare, L'Occident, Septembre, Vrai, La Météo Économique, Industrie (Fédération des Industries Belges), and also for Der Spiegel (Hamburg), Gazet van Antwerpen (Antwerp), Dzinnik Polski (London) and Europeo de Roma (Rome).

Any topic which presents possibilities of sensationalism or scandal inspires MOYEN, and he is known to write inaccurate and derogatory reports even on his supposed friends, including the American and Belgian intelligence services, as well as on his enemies, the Communists...

The French, Belgian, Swiss and Dutch intelligence services continue to receive MOYEN's product but, except for the Swiss Air Intelligence Service, apparently give it the low evaluation that MOYEN's reputation for unreliability merits...

[9] Even in Belgian Congo, where the uranium mines in the hands of the Union Minière had a major strategic importance for the American production of nuclear weapons.

They were therefore not allowed to fall into the hands of nationalist movements in Congo (Patrice Lumumba) or a left-wing democratic regime in Belgium.

At that time, the Société Génerale and its Congolese branch Union Minière also supported the BACB and gave them premises in Brussels, in the Comediennesstraat (comic strip trail?).
