On 25 July 1914, the Austro-Hungarian Minister of Foreign Affairs, Leopold Count Berchtold (pictured), sent a coded private telegram to the Austro-Hungarian Ambassador to Russia, Frigyes Count Szapary. In his telegram, Berchtold clarifies Point 5 of the Austro-Hungarian ultimatum to Serbia.
Count Berchtold to Count Szapary. Vienna, 25 July 1914.
Referring to your Excellency’s telegram of 24 July.
Since the plan of making Imperial and Royal functionaries assist in the suppression of the subversive movement in Servia (Point 5 of our demands [i.e. the Austro-Hungarian ultimatum to Serbia]) called forth so much opposition on [Russian Minister of Foreign Affairs] Herr Sazonov’s part, I shall ask your Excellency to explain to him, in strict confidence, that in putting forth this demand, we only had practical aims in view, and certainly did not mean, in any way, to offend Servia’s sovereignty. In writing “collaboration”, in Point 5, we were thinking of establishing a secret bureau de sûreté, similar to the Russian establishments in Paris and Berlin, in Belgrade, which would cooperate with the Servian police and administrative authority.
