Maybe worth mentioning the Italian soldiers in Kephalonia being shot en masse by the Germans also occupying this Greek Island and elsewhere during WW2. The true story being brought to light in the fictionalised book and later film "Captain Corelli's Mandolin". When I visited around 2001/2 whilst cruising the Med, all the small towns and villages had posters advertising the film, shooting having only recently been completed. I recall a long walk into the hills above the capital Argostoli and discovering a memorial to such Italian soldiers massacred out of fear they would turn on their German allies. It very sadly brought the story to life.
I shall have cause to remember again next month when we visit for a holiday on the island.
