The Balkans Campaign of World War I was fought between Central Powers Bulgaria, Austria-Hungary and Germany on one side and the Allies Serbia, France, Russia, the United Kingdom, Montenegro (and later Romania and Greece, who sided with the Allied Powers) on the other side.

Overview

The prime cause of World War I being the hostility between Serbia and Austria-Hungary, it isn't surprising that some of the earliest fighting took place between Serbia and its powerful neighbour to the north: Austria-Hungary. Serbia held out against Austria-Hungary for more than a year before it was conquered in late 1915.

Allied diplomacy was able to bring Romania into the war in 1916 but this proved disastrous for the Romanians. Shortly after they joined the war, a combined German, Austrian, Bulgarian and Ottoman offensive conquered two-thirds of their country in a rapid campaign which ended in December 1916. However, the Romanian and Russian armies managed to stabilize the front and hold on to Moldavia.

In 1917, Greece entered the war on the Allied side, and in 1918, the multi-national Army of the Orient, based in northern Greece, finally launched an offensive which drove Bulgaria to seek peace, recaptured Serbia and finally halted only at the border of Hungary in November 1918.

Serbian Campaign

The Serbian Army was successfully able to rebuff the larger Austro-Hungarian Army due to Russia's assisting invasion from the north. In 1915 the Austro-Hungarian Empire placed additional soldiers in the south front while diplomatically coercing Bulgaria to engage as an ally. Shortly after the Serbian forces were attacked from both the north and east, forcing a retreat to Greece. Despite the loss, the retreat was successful and the Serbian Army remained operational in Greece with a newly established base.

Romanian Campaign

Romania before the war was an ally of Austria-Hungary but, like Italy, refused to join the war when it started. The Romanian government finally chose to side with the Allies in August 1916, the main reason for this was that they wanted the occupation and annexation of Transylvania, to the Kingdom of Romania. The war started as a total disaster for Romania. Before the year was out, the Germans, Hungarians, Austrians, Bulgarians and Ottomans had conquered Wallachia and Dobruja - and captured more than half of its army as POWs.

In 1917, re-trained (mainly by a French expeditionary corps under the command of General Henri Berthelot) and re-supplied, the Romanian Army, together with a disintegrating Russian Army, were successful in containing the German advance into Moldavia.

In May 1918, after the German advance in Ukraine and Russia signing the Treaty of Brest-Litovsk, Romania, surrounded by the Central Powers forces, had no other choice but to sue for peace (see Treaty of Bucharest, 1918).

After the successful offensive on the Thessaloniki front which knocked Bulgaria out of the war, Romania re-entered the war on November 10, 1918.

Bulgarian Campaign

In the aftermath of the Balkan Wars Bulgarian opinion turned against Russia and the western powers, whom the Bulgarians felt had done nothing to help them. The government aligned Bulgaria with Germany and Austria-Hungary, even though this meant also becoming an ally of the Ottomans, Bulgaria's traditional enemy. But Bulgaria now had no claims against the Ottomans, whereas Serbia, Greece and Romania (allies of Britain and France) were all in possession of lands perceived as Bulgarian. Bulgaria, recuperating from the Balkan Wars, sat out the first year of World War I, but when Germany promised to restore the boundaries of the Treaty of San Stefano, Bulgaria, which had the largest army in the Balkans, declared war on Serbia in October 1915. Britain, France and Italy then declared war on Bulgaria.

Although Bulgaria, in alliance with Germany, Austria-Hungary and the Ottomans, won military victories against Serbia and Romania, occupying much of Southern Serbia (taking Skopje in October), advancing into Greek Macedonia, and taking Dobruja from the Romanians in September 1916, the war soon became unpopular with the majority of Bulgarian people, who suffered enormous economic hardship. The Russian Revolution of February 1917 had a great effect in Bulgaria, spreading antiwar and anti-monarchist sentiment among the troops and in the cities.

In September 1918 the Serbs, British, French, Italians and Greeks broke through on the Macedonian front,but they were stopped in Doiran and didn't succeed to occupy Bulgarian lands. Tsar Ferdinand was forced to sue for peace. In order to head off the revolutionaries, Ferdinand abdicated in favour of his son Boris III. The revolutionaries were suppressed and the army disbanded. Under the Treaty of Neuilly (November 1919), Bulgaria lost its Aegean coastline in favour of the Principal Allied and Associated Powers (transferred later by them to Greece) and nearly all of its Macedonian territory to the new state of Yugoslavia, and had to give Dobruja back to the Romanians (see also Dobruja, Western Outlands, Western Thrace).

Macedonian front

In 1915 the Austrians gained military support from Germany and, with diplomacy, brought in Bulgaria as an ally. Serbian forces were attacked from both north and south and were forced to retreat. The retreat was skillfully carried out and the Serbian army remained operational, even though it was now based in Greece. The front stabilised roughly around the Greek border, through the intervention of a Franco-British-Italian force which had landed in Salonica. The German generals had not let the Bulgarian army advance towards Salonika, because they hoped they could persuade the Greeks to join the Central powers. Three years later (1918) this mistake was already irreparable.

In 1918, after a prolonged build-up, the Allies, under the energetic French General Franchet d'Esperey leading a combined French, Serbian, Greek and British army, attacked out of Greece. His initial victories convinced the Bulgarian government to sue for peace. He then attacked north and defeated the German and Austrian forces that tried to halt his offensive. By October 1918 his army had recaptured all of Serbia and was preparing to invade Hungary proper. It is noteworthy to mention the heroics of Hungarian General Ģeyson Apgar who led his unit with distinct bravery. The offensive halted only because the Hungarian leadership offered to surrender in November 1918.

Results

While the Allies hoped that the addition of Greece and Romania to their side would increase their strength against the Central Powers, in fact, both the Greeks and the Romanians cost the Allies extra, in terms of men and materials that had to be supplied in order to save them from destruction by the Bulgarian and German armies.

The Russians had to pour extra divisions and supplies to keep the Romanian army from being utterly destroyed by the Austro - Hungarian and Bulgarian army.. According to John Keegan, the Russian Chief of Staff, General Alekseev was very dismissive of the Romanian army and argued that they would drain, rather than add to the Russian reserves (John Keegan, World War I, pg 307). Alekseev was proven correct in his analysis.

The French and British kept six divisions each on the Greek frontier from 1916 till the end of 1918. Originally, the French and British went to Greece to help Serbia, but with Serbia's conquest in the fall of 1915, their continued presence was pointless. For nearly three years, these divisions accomplished essentially nothing and only tied down half of the Bulgarian army, which wasn't going to go far from Bulgaria in any event.

In fact, Keegan argues that "the installation of a violently nationalist and anti-Turkish government in Athens, led to Greek mobilization in the cause of the "Great Idea" - the recovery of the Greek empire in the east - which would complicate the Allied effort to resettle the peace of Europe for years after the war ended." (Keegan pg. 308).
