Russian red mobilisation notices appear throughout St Petersburg and other parts of the country.

German ambassador protests to the Russian Foreign Minister. Vienna has agreed to talks. The Foreign Minister says Russia’s military measures are entirely precautionary. The ambassador asks to see the Tsar.

The ambassador tells the Tsar that Russian mobilisation will have a terrible impact. The Tsar says he is sending a message to the Kaiser saying Russian troops will not make any hostile moves.

At midnight the German ambassador delivers the ultimatum that Russia must start to demobilise by noon the next day otherwise Germany will mobilise.
