Analysis of the Sources collected

Most of the sources are newspaper from different political orientation, and one current event film, all from September 2nd or 3rd. Whatever the political orientation of the newspaper except « l’Humanité » - the official organ of the Communist Party which was banned in 1939-, we can notice the exposure, the denunciation of the German policy with reference to August 1914, or even 1870 (Bismarck), using some phrases such as “trickery – the mask has fallen”.
