In September the Allies began their final offensive to knock out Bulgaria out of the war. The Bulgarian Army which was stretched on a 350 km front with all its forced arrayed in a single line had little reserves to prevent a breakthrough at the Battle of Dobro Pole. General Nerezov's First Army was attacked by the British and Greeks at the Battle of Doiran. The fighting was hard but unlike other sectors of the front the Bulgarian troops kept their high morale and battle readiness due to the personal visits of the commander of the army on the battlefield. Unlike other commanders he had also positioned his forces in such a way that made available two infantry regiments as an immediate reserve. As a result, the Bulgarians achieved an important victory which encouraged general Nerezov to begin preparations for a counter-attack with his army. However the Senior German and Bulgarian commanders were overwhelmed by the Dobro Pole debacle and feared giving a last general battle with all available forces. Instead the First Army was ordered to retreat and for the remaining days of the war it was pursued by the British and fought only small rearguard battles. The war ended in Bulgarian defeat and the First Army was demobilized in October 1918.
