The twelve-hour moratorium that Germany gave to Russia to be able to make a declaration of loyalty, passed without results. The Kaiser just passed the order to immediately mobilize the entire German military forces.

Following the speech from the throne (August 4, 1914)
Emperor Wilhelm II made this speech in 1914:

“You have read, gentlemen, what I told my people from the balcony of the castle. I’m repeating it here, I know of no more parties, I only know Germans. In support, you will be determined, irrespective of party differences, differences of status or religion to abide by me through thick and thin, through deprivation and death. I call upon the party leaders to step forward and to give me their word for it.”
