The first volume of these very valuable and well-written memoirs ("Prelude to Dunkirk, July 1939-May 1940") covers the period from August 1939 to May 1940, with greatest emphasis on the last weeks when the author, a Conservative M.P., was Churchill's personal representative with Reynaud. The second volume ("The Fall of France, June 1940") covers the black weeks in France from June 1 to June 17.
