Here's the question..
Andrée De Jongh used to warn prospective helpers for the Comet Line that their operational life expectancy was no more than 6 months (maximum) before being arrested by the German security services.
And once arrested, the gloves were off. Unlike the aircrew, the provisions of the Geneva Convention didn't apply to civilian helpers of organisations such as Comet - so those arrested were subject to the grisly medieval methods of 'interrogation' employed by the Gestapo and the SD.. followed by execution or deportation to concentration camps.
So - what would you have done?
About 288 aircrew evaded successfully via the Pays Basque from 1941 to mid-June 1944 when the Normandy landings made transits through the fighting area too hazardous. After June 1944, Comet developed other methods of evasion for the aircrew and by the war's end a total of some 800 aircrew had been repatriated. Stopping the outflow of aircrew evaders via Comet became the priority for the Germans as the evaders were, for the most part, operational aircrew (some intelligence agents and saboteurs used Comet also).
Bear in mind that the Comet helpers were untrained amateurs and they had only their wits to rely on. In contrast, the security services of the Occupier had had several years to practice their dark arts. How much training had the aircrew in evading? Perhaps Danny can answer that one.
