The Voses began their resistance work when the Germans forced their Jewish friends to move into the Jewish quarter of
Amsterdam. One friend asked the Voses to hide a Jewish child and a piano from the Germans. The Voses agreed. Another friend asked them to hide a suitcase full of valuables. Once again, the Voses agreed. The Voses agreed to use their home as a hiding space for Jews. The Voses lived on a dead-end street, backing up to the woods, making transporting individuals discreetly an easier task. Jews seeking refuge at the Vos house were required to bring special identification paper work. In one instance, Johtje turned away a man begging for asylum because he failed to produce these identification. The Voses later discovered that he was a German informant. On one occasion, the
Gestapo arrested a member of the Laren group. In response, the Voses retrieved contraband from his home and buried it in their back yard. Soon afterwards, the Gestapo arrived at the Vos house with the resistance member, bloodied from torture . The Gestapo officers told the Voses to return the contraband or they would execute the prisoner. Johtje devised a plan to save him. He sent the man's wife to dig up the contraband and bring it to the Gestapo, telling them she found it at her brother-in-law's house (who was safe in hiding). The Gestapo released the prisoner. == Legacy ==
