Tuhia he tohutoro mō tēnei wāhanga - I pakaru te pakanga i te marama o Hepetema 1939, ā, mō te nuinga o ngā Parisians, he torutoru noa iho ngā huringa o te wā. Heoi, ehara i te mea ko te wheako o etahi mano o nga rerenga torangapu o Tiamana i rapu rerenga mai i te whakatoi ma te neke ki Paris. Ko Leo Bauer tētahi o te hunga i hopukina i Paris i te Mahuru 1939. I puritia ia i roto i ngā puni whakarau maha i waenganui i taua wā me te rangimarie o Wīwī-Tiamana
o Hune 1940. I te Hōngongoi 1940 i taea e ia te mawhiti ki Switzerland me tana hoa o te roopu. I noho kore ture ia i Switzerland i raro i te tuakiri o te kaimahi pēke i Geneva me te ingoa "Paul-Eric Perret". I noho ia hei kaiwhakarato korero / whakapiri ("Vertrauensmann") i te Hauauru o Switzerland ka uru atu ki nga "mahi rohe" e pa ana ki te rohe French-Swiss.
