The Channel Islands - during the German occupation were effectively a prison camp. Islanders could be - and were - executed for matters we would consider trivial (for instance keeping pigeons). The occupying Germans ensured their own comfort first - they commandeered houses, food, equipment. Following the Normandy landings, the British policy was to starve the Germans into submission. It was the islanders (mostly women, children and the elderly) who bore the brunt.
Your comments, Sassy, are crass and uncharitable. You have no conception of what life was like for five years for islanders - the final irony being that they were eventually liberated the day after WW2 ended, following which the German soldiers continued - under British command - to be used for law enforcement.
