On 27 July 1914, Laszlo Count Szogyeny, the Austro-Hungarian Ambassador to Germany (pictured), sent a coded private telegram to Leopold Count Berchtold, the Austro-Hungarian Minister of Foreign Affairs. In his telegram, Szogyeny adds to his telegram of the previous day which forsaw the imminent general mobilisation of the Russian Army.
Count Szogyeny to Count Berchtold. Berlin, 27 July 1914.
In addition to my telegram of yesterday.
In the Ministry of Foreign Affairs, I have just been informed, in strict confidence, that according to the latest news, the report that four years of reserves had been called up and orders for the mobilisation of the Russian military districts had been given is not confirmed.
[The Russian Minister of Foreign Affairs] Sazonov declared to the German Ambassador that he would guarantee that in Russia no mobilisation was taking place, though certainly necessary military precautions were being taken.
Moreover, the Russian minister of Foreign Affairs told [the German Ambassador to Russia] Count Pourtalès, that Russia would not mobilise, unless Austria-Hungary adopted a hostile attitude towards Russia. Russia wished to see peace maintained and hoped Germany would support it in this endeavour.
The German Military Attaché in Petersburg reports that “the Russian War Minister had given him his word of honour, that not a man and not a horse has been mobilised; but that certainly military measures have been taken”; measures, the German Military Attaché adds, which “are probably rather comprehensive”.
I beg your Excellency not to mention the report of the German Military Attaché to [the German Ambassador to Austria-Hungary] Herr von Tschirschky.
