Vingtième Siècle. Revue d'histoire - Année 1990 - Volume 25 - Numéro 1 - Pages 37-48The Franco-British split of 1940. The Supreme War Council from the invasion to the defeat of France, François Bédarida. Could the Supreme War Council, created during the summer of 1939 to unify French and British strategies, survive the storm of May-June 1940 ? Confronted with the traumatic rout of their army, most French leaders took the path of defeatism, while with Churchill, the British opted resolutely for a light at ail costs. From then on, as can be seen by following the various summit meetings, only a few weeks were needed to lead yesterday's alies to the breaking point. 12 pages Source : Persée ; Ministère de la jeunesse, de l’éducation nationale et de la recherche, Direction de l’enseignement supérieur, Sous-direction des bibliothèques et de la documentation.
