Editing Henriette Roosenburg (section)

===Trial and death sentence===

Jet was transferred to The Hague and interrogated severely and exhaustingly, but she managed to protect the new intelligence line and her coworkers. In July 1944, she and 19 other members of the former resistance group Fiat Libertas were moved to [[Utrecht]], the Netherlands, for their trial. Here, Jet again met up with Nel Lind, whom she had known previously as the organizer of the escape line for Allied pilots. She also met [[Joke Folmer]] for the first time. Joke (pronounced "Yo-kuh") had proven to be a competent and successful guide, who until her arrest in April 1944 had helped 320 people escape to Belgium. Half of them were Allied air men and many of them managed to return to England. Both women would become her companions until the end of the war and during their subsequent journey home. They figure prominently in "The Walls came tumbling down".

The group were court-martialled by the German army on the charge of 'Feindbegünstigung', aiding and abetting the enemy, because their espionage activities and assistance to Allied pilots had undermined the interests of the German army, and had favoured enemy forces. Joke, Nel and Jet were sentenced to death; Jet even thrice, with the advice to absolutely carry out the sentence, since she was considered very dangerous.
