Armée d'Orient (1915–1919)

The Armée d'Orient was a field army of the French Army during World War I who fought on the Macedonian front.
The Armée d'Orient was formed in September 1915 during the Conquest of Serbia by German-Austrian-Bulgarian forces. It was shipped to the Greek port of Salonika, where its first units arrived on 5 October.
Despite several offensives, the front stabilized on the Greek-Serbian border until September 1918, when the Bulgarian army disintegrated after defeat in the Battle of Dobro Pole.
On 11 August 1916, all allied troops on the Salonika front came under a united command, and named Allied Army of the Orient. The AAO supreme commander became the French commander of the Armée d'Orient Maurice Sarrail. He was succeeded as commander of the Armée d'Orient by Victor Cordonnier, and the army itself was renamed the Armée française d'Orient.
