Overview:Neil Oliver visits Ile de Sein, a tiny 'Island of Heroes' off the coast of Brittany. The island was honoured with a prestigious military award by President De Gaulle after virtually every man on the island took to their boats at the start of the Second World War to join De Gaulle in England and fight with the 'Free French' forces. The last survivors re-live the moving incident that motivated an entire island to go to war.
