Author Robert Edsel discusses his new book, "Rescuing da Vinci". Edsel says that the campaign to protect Europe's artistic and cultural heritage during the conflict is a new way of understanding the magnitude and impact of the Second World War. Edsel's work chronicles the story of the "Monument's Men", a group of 350 men and women from 12 Allied nations, who volunteered to protect great works of art during the war.
