On 23 July 1914, the Austro-Hungarian Ambassador to Russia Frigyes Count Szapary (pictured) sent a coded private telegram to the Austro-Hunarian Minister of Foreign Affairs Leopold Count Berchtold. In his telegram, Szapary reassures Berchtold about his conversation with the French President Raymond Poincaré.
Count Szapary to Count Berchtold. Saint Petersburg, 23 July 1914.
My German colleague judges from the similarity of the language used by [Russian Minister of Foreign Affairs] Herr Sazonov before the arrival of [French President] Poincaré, with that used by the President, that the latter had had a lesson from Sazonov, who wished in this way to make a greater impression.
This explains that Sazonov is telling everybody that Poincaré found me very much excited against Servia, whilst I, for reasons that will be easily understood, observed the greatest reserve.
