Book excerpt: In 1940, at the French port of Dunkirk, more than 300,000 trapped Allied troops were dramatically rescued from destruction at the hands of Nazi Germany by an extraordinary seaborne evacuation. The true history of the soldiers, sailors, airmen and civilians involved in the nine-day skirmish has passed into legend. Now, in this gift edition, the story Winston Churchill described as a 'miracle' is narrated by bestselling author Joshua Levine in its full, sweeping context, including new interviews with veterans and survivors.
