The Gallipoli campaign, the Dardanelles campaign, the Defense of Gallipoli or the Battle of Gallipoli was a military campaign in the First World War on the Gallipoli peninsula from 19 February 1915 to 9 January 1916. The Entente powers, Britain, France and the Russian Empire, sought to weaken the Ottoman Empire, one of the Central Powers, by taking control of the Ottoman straits. This would expose the Ottoman capital at Constantinople to bombardment by Entente battleships and cut it off from the Asian part of the empire. With Turkey defeated, the Suez Canal would be safe and a year-round Entente supply route could be opened through the Black Sea to warm-water ports in Russia.
General Erich Georg Sebastian Anton von Falkenhayn was the second Chief of the German General Staff of the First World War from September 1914 until 29 August 1916. Falkenhayn was removed on 29 August 1916 after the failure of his offensive strategy in the west at the Battle of Verdun, the opening of the Battle of the Somme, the Brusilov Offensive and the Romanian entry into the war. Having planned to win the war before 1917, the German army was reduced to hanging on.
The Second Battle of Krithia continued the Allies' attempts to advance on the Helles battlefield during the Battle of Gallipoli of the First World War. The village of Krithia and neighbouring hill of Achi Baba had to be captured in order for the British to advance up the Gallipoli peninsula to the forts that controlled passage of the Dardanelles straits. A small amount of ground was captured after two days of costly fighting, but the objectives remained out of reach.
The Third Battle of Krithia, fought on the Gallipoli peninsula during World War I, was the last in a series of Allied attacks against the Ottoman defences aimed at achieving the original objectives of 25 April 1915. The previous failures in the first and second battles resulted in a less ambitious plan being developed for the attack, but the outcome was another costly failure for the Allies. The allied aim was, as always, to facilitate the capture of Alçı Tepe which commanded most of the peninsula.
The Battle of Gully Ravine (Zığındere) was a World War I battle fought at Cape Helles on the Gallipoli peninsula. By June 1915 all thoughts the Allies had of a swift decisive victory over the Ottoman Empire had vanished. The preceding Third Battle of Krithia and the attack at Gully Ravine had limited objectives and had much in common with the trench warfare prevailing on the Western Front. Unlike previous Allied attacks at Helles, the Gully Ravine action was largely successful at achieving its objectives, though at a typically high cost in casualties.
The Middle Eastern theatre of World War I saw action between 29 October 1914 and 30 October 1918. The combatants were, on one side, the Ottoman Empire, with some assistance from the other Central Powers; and on the other side, the British as well as troops from the British Dominions of Australia, Canada, and New Zealand, the Russians, and the French from among the Allied Powers. There were five main campaigns: the Sinai and Palestine, Mesopotamian, Caucasus, Persian, and Gallipoli campaigns.
The Gorlice–Tarnów offensive during World War I was initially conceived as a minor German offensive to relieve Russian pressure on the Austro-Hungarians to their south on the Eastern Front, but resulted in the Central Powers' chief offensive effort of 1915, causing the total collapse of the Russian lines and their retreat far into Russia. The continued series of actions lasted the majority of the campaigning season for 1915, starting in early May and only ending due to bad weather in October.
The Macedonian front, also known as the Salonica front, was a military theatre of World War I formed as a result of an attempt by the Allied Powers to aid Serbia, in the autumn of 1915, against the combined attack of Germany, Austria-Hungary and Bulgaria. The expedition came too late and with insufficient force to prevent the fall of Serbia and was complicated by the internal political crisis in Greece. 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 stable, despite local actions, until the Allied offensive in September 1918 resulted in Bulgaria capitulating and the liberation of Serbia.
The Battle of Krivolak was a World War I battle, fought between 21 October and 22 November 1915. It was fought in the initial stage of the Macedonian campaign, in the Balkans Theatre. On 21 October, Bulgarian troops attacked the French-held positions near the Strumica rail station, at the time part of the Kingdom of Serbia, starting the battle. Fighting continued until 22 November, when two Serbian divisions failed to capture Skopje, thus rendering the continuation of Entente offensive operations dangerous and forcing the French to evacuate their forces from the region.
The Kamerun campaign took place in the German colony of Kamerun in the African theatre of the First World War when the British, French and Belgians invaded the German colony from August 1914 to March 1916. Most of the campaign took place in Kamerun but skirmishes also broke out in British Nigeria. By the Spring of 1916, following Allied victories, the majority of German troops and the civil administration fled to the neighbouring neutral colony of Spanish Guinea. The campaign ended in a defeat for Germany and the partition of its former colony between France and Britain.

The Battle of Kosturino was a World War I battle fought between 6 and 12 December 1915. It was fought in the initial stage of the Macedonian campaign, in the Balkans Theatre. On 6 December, Bulgarian troops attacked the French and British-held trenches in Kosturino, at the time part of the Kingdom of Serbia. Though the early offensive was held in check, on 8 December, Bulgaria managed to infiltrate the Memesli ravine. Bulgaria then seized Crete Simonet, thus threatening to outflank the Allies. The Entente defeat at Kosturino led to the complete withdrawal of Allied forces from Serbia, thus enabling the Central Powers to build the Berlin to Constantinople rail line. In the meantime, the Allies concentrated on solidifying their defenses in Greece.
The Ottoman Empire came into World War I as one of the Central Powers. The Ottoman Empire entered the war by carrying out a surprise attack on the Black Sea coast of Russia on 29 October 1914, with Russia responding by declaring war on 2 November 1914. Ottoman forces fought the Entente in the Balkans and the Middle Eastern theatre of World War I. The Ottoman Empire's defeat in the war in 1918 was crucial in the eventual dissolution of the empire in 1922.

The Battle of Kumkale was a World War I battle fought between Ottoman and French forces.

Kumkale is the name of a village which now is a part of Troy national park.
