On 24 July 1914, Laszlo Count Szogyeny, the Austro-Hungarian Ambassador to Germany (pictured), sent a coded telegram to Leopold Count Berchtold, the Austro-Hungarian Minister of Foreign Affairs. In his telegram, Szogyeny informs Berchtold of German public opinion towards Austria-Hungary.
Count Szogyeny to Count Berchtold. Berlin, 24 July 1914.
The press of this city—as far as I can judge it—is full of praise on the subject of our Note to Servia [i.e. the Austro-Hungarian ultimatum to Serbia]. A paragraph of the Berliner Lokalanzeiger, which is believed to be officially inspired, gives the assurance that the German people are breathing more freely, since steps have been taken for clearing up matters in the Balkans. Germany congratulates her ally on the Danube [i.e. Austria-Hungary] for taking this resolution, and will not fail to give proof of true friendship and ready help in the trying times that may be approaching.
