From 6 January to 19 January 1941, he was in Paris to set up a second network, meeting with Max André, Jan Doornik and numerous other members of the French Resistance. Back in Nantes on 20 January, he came back to the Cléments who reported to him suspicious activities by the radio operator Gaessler, seen hanging around in bars and talking with German soldiers. When interrogated, Gaessler said that this was a good way to gather information. D'Estienne d'Orves decided to lay down Marty at the next trip to London but, two days later, the Gestapo stormed the house and arrested him. After a brief resistance, a wounded and handcuffed d'Estienne d'Orves was brought to Angers, along with his companions.
