Belgium imprisoned Belgian nationals who had collaborated with the Nazis and executed some. One Belgian to be sentenced to execution was Pierre Daye, however he was one of the first Nazi collaborators to escape Europe, and unusually by plane. He fled to Argentina with the help of Charles Lescat, also collaborator of "Je suis partout". Once in Argentina he attended a meeting organised by Juan Perón in the "Casa Rosada" during which a network (colloquially called ratlines) was created, to organise the escape of collaborators and former Nazis. On 17 June 1947, Belgium requested his extradition from Argentina, however the Argentine Government ignored this request. Now secure in his freedom, Pierre Daye resumed his writing activities, becoming the editor of an official Perónist review.
