Vardar offensive

World War I military operation

The Vardar offensive was a World War I military operation, fought between 15 and 29 September 1918. The operation took place during the final stage of the Balkans Campaign. On 15 September, a combined force of Serbian, French, and Greek troops attacked the Bulgarian-held trenches in Dobro Pole, at the time part of Serbia. The assault and the preceding artillery preparation had devastating effects on Bulgarian morale, eventually leading to mass desertions.
