'Janine de Greef, who died a couple of months ago aged 95, was a teenage courier for the Comet escape line that linked occupied Belgium to neutral Spain during the second world war. For three years she escorted allied servicemen from Paris to the south-west city of Bayonne by train, or from Bayonne to the foothills of the Pyrenees by tram or bicycle' (here). There are no words that can adequately express one's admiration for someone like Janine de Greef. (Apparently the book to read about the Comet escape line is Airey Neave's Little Cyclone.)
