The German advance causes the Eastern Macedonian Army to stop fighting

With the Germans sweeping down through the Axios valley, they reached the point where nothing stood between them and Salonika. That news was enough to bring the commander of the Greek Eastern Macedonian Army to ask for an armistice. While the Greeks were doing well in Albania, the overall situation stopped their offensive. He decided to withdraw towards the line that General Wilson had proposed to defend. General Papagos had issued orders to Wilson, but Wilson had decided to make his own moves. General Wilson planned to assemble a force to block the Florina gap. Wilson appointed General Mackay to command the force and Wilson wanted him directly under his command. This is based on the account in Vol.II of the Australian Official History.
