Immediately following the battle, Entente forces were defeated in the Battle of Doiran at Lake Doiran on 18 September.
However, the breach of the defensive line at Dobro Pole enabled the Allies to penetrate into Vardar Macedonia and send reinforcements to Doiran.
The Bulgarians rushed to the defense of their homeland, abandoning Vardar Macedonia, in order to prevent a future occupation by the Entente.
Having suffered heavy losses at Doiran, the Allied forces allowed the Bulgarians to peacefully withdraw over the border.
A combination of multiple factors, including combat fatigue and poor supplies, led to the Radomir Rebellion.
On 25 September, a band of Bulgarian deserters who had previously fled from Dobro Pole arrived at Kyustendil, looting the city and putting the Bulgarian High Command to flight.
The mass of retreating Bulgarian mutineers then converged on the railway center of Radomir in Bulgaria, just 30 miles (48 km) from the capital city of Sofia.
On 27 September, the leaders of the Bulgarian Agrarian National Union took control of these troops and proclaimed the establishment of the Bulgarian Republic.
About 4,000–5,000 rebellious troops threatened Sofia the following day.

Under those chaotic circumstances a Bulgarian delegation arrived in Thessaloniki to ask for an armistice.
On 29 September, the Bulgarians were granted the Armistice of Salonica by General d'Esperey.
The Bulgarian downfall turned the strategic and operational balance of the war against the Central Powers.
The Macedonian Front was brought to an end at noon on 30 September, when the ceasefire came into effect, and the Radomir Rebellion was put down, by Bulgarian forces, as of the 2 October.
Tsar Ferdinand I of Bulgaria abdicated and went into exile the following day.

Importance of Armistice of Salonica was best described by German Emperor Wilhelm II in his telegram to Bulgarian Tsar Ferdinand I: “Disgraceful!
62,000 Serbs decided the war!".
On 29 September 1918, the German Supreme Army Command informed Kaiser Wilhelm II and the Imperial Chancellor Count Georg von Hertling, that the military situation facing Germany was hopeless .

The British Army headed east towards the European side of the Ottoman Empire, while the French and Serbian forces continued north.
The British Army neared Constantinople and, without a force capable to stopping the advance, the Ottoman government asked for an armistice (the Armistice of Mudros) on 26 October.
In Serbia, "Desperate Frankie" (as the British nicknamed d'Esperey) continued to advance and the Serbo-French Army re-captured the country, overrunning several weak German divisions that tried to block its push near Niš.
On 3 November, Austria-Hungary was forced to sign an armistice on the Italian Front ending the war there.
On 10 November, d'Esperey's army crossed the Danube river and was poised to enter the Hungarian heartland.
At the request of the French general, Count Mihály Károlyi, leading the Hungarian government, came to Belgrade and signed another armistice.
