Count Szogyeny, the Austro-Hungarian Ambassador to Berlin, sent a strictly confidential telegram to Count Berchtold, the Minister of Foreign Affairs, on 9 July 1914. The message confirmed German resolve for swift action against Serbia. The German Secretary of State, Gottlieb von Jagow (pictured), was among the key decision-makers in Berlin arguing for decisive Austrian action.
Count Szogyeny to Count Berchtold. Berlin, 9 July 1914.
I have sent your Excellency’s warmest thanks to the Imperial chancellor, who is on leave in Hohenfinow, by the state secretary, only just returned from leave.
I have been able to ascertain that the state secretary perfectly agrees with the attitude the German government has adopted and is most decidedly of opinion that the action proposed against Servia should be taken in hand without delay.
The German minister in Bucharest is instructed to hold back the intended communication to King Carol about the negotiations with Bulgaria, which as far as he—Jagow—knows, have not yet begun in
any concrete form.
