11-17 July: The German military attaché in Vienna keeps Moltke and Waldersee informed about Vienna’s intentions, even though they are on holiday.
An Austro-Hungarian staff officer tells the attaché Austria-Hungary will send an unacceptable note to Serbia and war is certain. He has the date of the note so Moltke and Waldersee know when to return to Berlin.
On one letter Moltke makes the marginal note “Austria must beat the Serbs and then make peace quickly, demanding an Austro-Serbian alliance as the sole condition as Prussia did with Austria in 1866”.
