To the east, General Bülow launches the attack agreed to yesterday by Falkenhayn. Though the right of the BEF is able to hold, the Germans are able to push the French 5th Army southwards, capturing the high ground at Brimont, just 9000 yards north of Rheims.

- Though most of the German 6th Army is to be redeployed to northern France, some units are to remain to hold the line in Lorraine. Today, those units are formed into Army Detachment Falkenhausen, named for its commander, General Freiherr von Falkenhausen, formerly commander of the Ersatz Corps. In this context, an 'army detachment' is precisely that - a detached portion of an army under a separate commander and assigned different tasks. It reflects Falkenhayn's intention that the front south of Nancy is to be largely quiet, as units are transferring to the open northern flank.
- The governor of German New Guinea has been facing an increasingly impossible situation in his defense of the colony since the landing of the Australians six days earlier. In addition to being overwhelming outnumbered and without any prospect of reinforcement, he feels he can no longer rely on the loyalty of his indigenous soldiers, and his German soldiers are increasingly waylaid by dysentry and malaria. As such, the German governor surrenders New Guinea to the commander of the Australian expedition, delivering the entirety of the colony, both its islands and the mainland, to Australian occupation.
- In Australia, Labour party leader Andrew Fisher becomes Prime Minister after his party emerged victorious from the recent election which had been called just before the outbreak of war in Europe. Fisher is fully committed to supporting the British war effort - in a campaign speech on July 31st, he had famously declared that Australia will defend Britain 'to our last man and our last shilling'.
