Looking for reindeer in Norway 1944

[F19Gladiator]

I've read in a book last year that when the Germans were to withdraw from northern Norway they told (ordered) the Same reindeer owners to drive their herds towards the west but they fooled the Germans and draw them towards the south and south-east instead, away from the Germans who retreated in a western direction along the northern coast road. It would have been near impossible for the Germans to track the reindeer herds in a terrain without roads while it would have been possible to find them from the air in good weather. They would still hardly be able to do much about where the reindeer were driven. This might be the reason for the flight note in the Flugbuch. I suppose the reason was to deny the Russians a potential food supply when retreating. Sadly the 'scorched earth' tactics were used by the Germans during the retreat in northern Norway, burning down the houses, farms and killing the farm animals. I don't remember the title of the book but I will remember it was in Norwegian language. It is probably still crated in my moving boxes.
