 The Greek entry into the war, along with the 24 division reinforcements that the army had received in the spring of the same year, created a strategic advantage for the Entente.In late July 1918, Bulgarian commander-in-chief Nikola Zhekov sent German field marshal general Paul von Hindenburg a message regarding a rumored Entente offensive, and detailed Bulgaria's inability to adequately defend the Vardar portion of the front.Zhekov requested that Germany immediately reinforce the Balkan Front, hinting that Austria-Hungary would also be required to strengthen its positions in Albania.
