As a young subaltern in the Coldstream Guards, the author lost his arm at Dunkirk and was captured but eventually escaped via Lille, Paris, Marseilles, Spain and Gibraltar. He describes the fierce fighting outside Dunkirk, his captivity, escape and extraordinary life in Vichy France, before the Germans controlled it. His fellow escapees and the French who sheltered them make a rich cast of characters. On return to London, Langley is recruited into the Secret Service and told to organise the safe return of allied soldiers, sailors and airmen who had succeeded in either escaping from or evading the Germans. He describes the astonishing courage and sacrifice of the heroic underground operators who ran these escape lines across Belgium and France. Despite betrayal and infiltration from Germans, collaborators and traitors, over 3000 men were safely brought back to fight another day. Langley and Airey Neave, who joined him after his historic home run from Colditz, had to wrestle with rival secret organisations for resources to carry out their vital work. All this and more is brilliantly described in this gripping, beautifully written book.
