Question: The Armée d'Orient fought on the front that was created as an aid to what country?

full_context: Document 1: Army of the West (1793): The Army of the West ("armée de l'Ouest") was one of the French Revolutionary Armies. It was created on 1 August 1793 by merging the armée des côtes de Brest, the armée des côtes de La Rochelle, and the armée de Mayence, and was sent to fight the revolt in the Vendee.
Document 2: Order of battle of the Armée d'Orient (1798): The Armée d'Orient (English: "Army of the Orient") was the French military force gathered by the French Directory to send on the expedition to Egypt in 1798. The expedition had the intention of barring Great Britain's route to its colonies in India and was put under the command of Napoleon Bonaparte. Also known as Battle of Orient.
Document 3: Polish Armed Forces in the East (1914–20): Polish Armed Forces in the East around World War I is a term used for several Polish military formations formed in Russia and operating in the period of 1914–1920 (First World War, Russian Revolution of 1917, and the early stages of the Polish-Ukrainian War and Polish-Soviet War. Early formations were part of the Imperial Russian Army. Later, during the Russian Revolution, the Polish formations were mainly allied to the White Russian forces and the Western powers (both the German Empire and the Entente). All the formations (or their remains) were eventually incorporated into the Polish Army by 1920.
Document 4: Army of the Midi: The Army of the Midi ("Armée du Midi") was a unit of the French army, stationed in the Midi region and created by royal decree of Louis XVI on 13 April 1792. It existed under this name for less than five months, and was split by a decree of the National Convention dated 1 October 1792 into the "Armée des Alpes" and the "Armée des Pyrénées". Another "Armée du Midi" was later gathered by Napoleon for the Peninsular War.
Document 5: Albanian nationalism (Kosovo): Kosovo is the birthplace of the Albanian nationalist movement which emerged as a response to the Eastern Crisis of 1878. In the immediate aftermath of the Russo-Ottoman war, the Congress of Berlin proposed partitioning Ottoman Albanian inhabited lands in the Balkans among neighbouring countries. The "League of Prizren" was formed by Albanians to resist those impositions. For Albanians those events have made Kosovo an important place regarding the emergence of Albanian nationalism. During the remainder of the late Ottoman period various disagreements between Albanian nationalists and the Ottoman Empire over socio-cultural rights culminated in two revolts within Kosovo and adjacent areas. The Balkan Wars (1912-13) ending with Ottoman defeat, Serbian and later Yugoslav sovereignty over the area generated an Albanian nationalism that has become distinct to Kosovo stressing Albanian language, culture and identity within the context of secession from Serbia. Pan-Albanian sentiments are also present and historically have been achieved only once when part of Kosovo was united by Italian Axis forces to their protectorate of Albania during the Second World War.
Document 6: Albanian nationalism (Republic of Macedonia): Albanian nationalism in the Republic of Macedonia came about during the Albanian nationalist movement which emerged as a response to the Eastern Crisis (1878) and proposed partitioning of Ottoman Albanian inhabited lands in the Balkans among neighbouring countries. During the remainder of the late Ottoman period various disagreements culminated between Albanian nationalists and the Ottoman Empire over socio-cultural rights. The Balkan Wars (1912-13) ending with Ottoman defeat, Serbian and later Yugoslav sovereignty over the area generated an Albanian nationalism that has become distinct to Macedonia stressing Albanian language, culture and identity within the context of state and sociopolitical rights. Pan-Albanian sentiments are also present and historically have been achieved only once when western Macedonia was united by Italian Axis forces to their protectorate of Albania during the Second World War.
Document 7: Greek Summer Offensive (1920): The Greek Summer Offensive of 1920 was an offensive by the Greek army, assisted by British forces, to capture the southern region of the Sea of Marmara and the Aegean Region from the Kuva-yi Milliye (National Forces) of the provisional Turkish national movement government in Ankara. Additionally, the Greek and British forces were supported by the Kuva-yi Inzibatiye (Forces of Order) of the Ottoman government in Constantinople, which sought to crush the Turkish nationalist forces. The offensive was part of the Greco-Turkish War and was one of several engagements where British troops assisted the advancing Greek army. British troops actively took part in invading coastal towns of the Sea of Marmara. With the approval of the Allies, the Greeks started their offensive on 22 June 1920 and crossed the 'Milne Line'. The 'Milne Line' was the demarcation line between Greece and Turkey, laid down in Paris. Resistance by the Turks was limited, as they had few and ill-equipped troops in western Anatolia. They were also busy on the eastern and southern fronts. After offering some opposition, they retreated to Eskişehir on Mustafa Kemal Pasha's order.
Document 8: Battle of the Frontiers: The Battle of the Frontiers was a series of battles fought along the eastern frontier of France and in southern Belgium shortly after the outbreak of World War I. The battles resolved the military strategies of the French Chief of Staff General Joseph Joffre with Plan XVII and an offensive interpretation of the German "Aufmarsch II" deployment plan by Helmuth von Moltke the Younger. The German concentration on the right (northern) flank, to wheel through Belgium and attack the French in the rear, was delayed by the movement of General Charles Lanrezac's Fifth Army towards the north-west to intercept them and the presence of the British Expeditionary Force (BEF) on his left flank. The Franco-British were driven back by the Germans, who were able to invade northern France. French and British rearguard actions delayed the German advance, allowing the French time to transfer their forces to the west to defend Paris, resulting in the First Battle of the Marne.
Document 9: Austro–Serbian Alliance of 1881: The Austro–Serbian Alliance of 1881 was a secret political alliance signed on 28 June 1881 between the Austro-Hungarian Empire and the Principality of Serbia. It resulted in the effective association of Serbia with Austria-Hungary and the coming Triple Alliance. The Balkans had been divided into spheres of influence, where Austria took the western part (including Serbia) and Russia took the eastern part (including Bulgaria). The treaty came after the railway convention of 6 April 1881 for the construction of the Belgrade–Niš section of the Vienna–Constantinople railway, and the trade treaty of 6 May 1881 which made Austria-Hungary virtually the sole market for agricultural products from Serbia and thereby dominant.
Document 10: Armée d'Orient (1915–19): The Armée d'Orient (AO) was a Field army of the French Army during World War I who fought on the Macedonian Front.
Document 11: American Expeditionary Forces: The American Expeditionary Forces (AEF) was the expeditionary force of the United States Army during World War I. It was established on July 5, 1917, in France under the command of General John J. Pershing. During the United States campaigns in World War I it fought alongside the French Army, British Army, and Canadian Army on the Western Front, against the German Empire. A minority of the AEF troops also fought alongside the Italian Army in that same year, against the Austro-Hungarian Army. The AEF helped the French Army on the Western Front during the Aisne Offensive (at the Battle of Château-Thierry (1918) and Battle of Belleau Wood) in the summer of 1918, and the AEF fought its major actions in the Battle of Saint-Mihiel and the Meuse-Argonne Offensive in the latter part of 1918.
Document 12: Central Powers: The Central Powers (German: "Mittelmächte" ; Hungarian: "Központi hatalmak" ; Turkish: "İttifak Devletleri" or "Bağlaşma Devletleri" ; Bulgarian: Централни сили "Tsentralni sili" ), consisting of Germany, Austria-Hungary , the Ottoman Empire and Bulgaria – hence also known as the Quadruple Alliance (German: "Vierbund" ) – was one of the two main factions during World War I (1914–18). It faced and was defeated by the Allied Powers that had formed around the Triple Entente. The Powers' origin was the alliance of Germany and Austria-Hungary in 1879. The Ottoman Empire and Bulgaria did not join until after World War I had begun, although the Ottoman Empire retained close relations with both Germany and Austria-Hungary since the beginning of the 20th century.
Document 13: Macedonian Front: The Macedonian Front of World War I, also known as the Salonica Front (after Thessaloniki), was formed as a result of an attempt by the Allied Powers to aid Serbia, in the fall of 1915, against the combined attack of Germany, Austria-Hungary and Bulgaria. The expedition came too late and in insufficient force to prevent the fall of Serbia, and was complicated by the internal political crisis in Greece (the "National Schism"). Eventually, a stable front was established, running from the Albanian Adriatic coast to the Struma River, pitting a multinational Allied force against the Bulgarian Army, which was at various times bolstered with smaller units from the other Central Powers. The Macedonian Front remained quite stable, despite local actions, until the great Allied offensive in September 1918, which resulted in the capitulation of Bulgaria and the liberation of Serbia.
Document 14: Balkan League: The Balkan League was an alliance formed by a series of bilateral treaties concluded in 1912 between the Balkan states of Greece, Bulgaria, Serbia and Montenegro, and directed against the Ottoman Empire, which at the time still controlled much of the Balkan peninsula. The Balkans had been in a state of turmoil since the early 1900s, with years of guerrilla warfare in Macedonia followed by the Young Turk Revolution and the protracted Bosnian Crisis. The outbreak of the Italo-Turkish War in 1911 had further weakened the Ottomans and emboldened the Balkan states. Under Russian influence, Serbia and Bulgaria settled their differences and signed an alliance, originally directed against Austria-Hungary on 13 March 1912, but by adding a secret chapter to it essentially redirected the alliance against the Ottoman Empire. Serbia then signed a mutual alliance with Montenegro, while Bulgaria did the same with Greece. The League was victorious in the First Balkan War which broke out in October 1912, where it successfully wrestled control of almost all European Ottoman territories. Following this victory however, unresolved prior differences between the allies re-emerged over the division of the spoils, particularly Macedonia, leading to the effective break-up of the League, and soon after, on 16 June 1913, Bulgaria attacked her erstwhile allies, beginning the Second Balkan War.
Document 15: Albania during World War I: Albania during World War I was an independent state, having gained independence from the Ottoman Empire on November 28, 1912, recognized by the Great Powers in 1913. A new country with various ethnic groups, it quickly unraveled and just a few months after taking power, its leader William of Wied, was forced to flee. After World War I broke out, anarchy took hold of the country as tribes and regions rebelled against central rule. To protect the Greek minority, Greek control was established in the southern districts replacing the Northern Epirote units. In response to this, Italy also landed troops, while Serbia and Montenegro took control of northern regions. In 1915 Serbia was overrun by the Austro-Hungarian Army and the Serbian army retreated through Albania, quickly followed by the Austro-Hungarian Army. As a result, the Austrians occupied most of the country, until a multinational Allied force broke through Austrian and German lines in 1918.
