Oversteegen, her sister, and friend Hannie Schaft worked to sabotage the Nazi military presence in the Netherlands.[5] They used dynamite to disable bridges and railroad tracks.[6] They also smuggled Jewish children out of the country or helped them escape concentration camps.[2]
The Oversteegens and Schaft also killed German soldiers, with Freddie being the first of the girls to kill a soldier by shooting him while riding her bicycle.[1][5] They also lured soldiers to the woods under the pretense of a romantic overture and then killed them.[1][5] Oversteegen would approach the soldiers in taverns and bars and ask them to “go for a stroll” in the forest.[2][5]
This might be why. Specifically that last part about luring Nazis with pretence of “romantic encounters” to the woods, to be shot.
