Archival footage of the Channel Islands under Nazi rule, here
The footage shows some of the thousands of forced laborers transported to the Channel Islands to build fortifications for the Nazis. An historian points out that these forced laborers, who came from all over Europe, were slaves, kept in miserable conditions, fed very little, beaten and tortured.
I've pointed out repeatedly on this blog how Hollywood-style products romanticize Nazis, thus reinforcing the Bieganski stereotype. You can find such criticism here. I mention "Island at War," a miniseries that depicts the wartime Nazi ruler of the Channel Islands as a desirable, romantic lead.
