After the French armistice of 22 June 1940, Rajchmann went through processing and was released in July-August 1940 and later met his father in Revel. In August 1940 he was contacted by Trepper who ordered him to travel to Toulouse where he would meet Comintern agent and courierMalvina Gruber, who would escort him back to Brussels to continue to provide documentation support to the Soviet espionage group there. In September or October 1940, Rajchmann met Gruber and they crossed the demarcation line in Bordeaux. Rajchmann left Gruber to meet his wife in Paris at the Caron Hotel in The Marais. At the hotel, Rajchmann met up with Bob Isbutzki, in reality Hermann Isbutzki, who arranged for Rajchmann to meet Trepper, who ordered him to travel back to Brussels to continue his work providing identity documents for the group.
