Allies (World War I) in the context of "Newfoundland"

The partition of the Ottoman Empire (30 October 1918 – 1 November 1922) was a geopolitical event that occurred after World War I and the occupation of Constantinople by British, French, and Italian troops in November 1918. The partitioning was planned in several agreements made by the Allied Powers early in the course of World War I, notably the Sykes–Picot Agreement, after the Ottoman Empire had joined Germany to form the Ottoman–German alliance. The huge conglomeration of territories and peoples that formerly comprised the Ottoman Empire was divided into several new states. The Ottoman Empire had been the leading Islamic state in geopolitical, cultural, and ideological terms. The partitioning of the Ottoman Empire after the war led to the domination of the Middle East by Western powers such as Britain and France, and saw the creation of the modern Arab world and the Republic of Turkey. Resistance to the influence of these powers came from the Turkish National Movement but did not become widespread in the other post-Ottoman states until the period of rapid decolonization after World War II.

The League of Nations mandate granted the French Mandate for Syria and the Lebanon, the British Mandate for Mesopotamia (later Iraq) and the British Mandate for Palestine, later divided into Mandatory Palestine and the Emirate of Transjordan (1921–1946). The Ottoman Empire's possessions in the Arabian Peninsula became the Kingdom of Hejaz, which the Sultanate of Nejd (today Saudi Arabia) was allowed to annex, and the Mutawakkilite Kingdom of Yemen. The Empire's possessions on the western shores of the Persian Gulf were variously annexed by Saudi Arabia (al-Ahsa and Qatif), or remained British protectorates (Kuwait, Bahrain, and Qatar) and became the Arab States of the Persian Gulf.

The Armistice of Mudros (Turkish: Mondros Mütarekesi) ended hostilities in the Middle Eastern theatre between Ottoman Turkey and the Allies of World War I. It was signed on 30 October 1918 by the Ottoman Minister of Marine Affairs Rauf Bey and British Admiral Somerset Arthur Gough-Calthorpe, Commander-in-Chief of the British Mediterranean Fleet, on board HMS Agamemnon (1906) in Moudros harbor on the Greek island of Lemnos. It took effect at noon the next day. The table it was signed on is now on board HMS Belfast in London Bridge, though it is not accessible to the public.

Among its conditions, the Ottomans surrendered their remaining garrisons outside Anatolia, and granted the Allies the right to occupy forts controlling the Straits of the Dardanelles and the Bosporus and any Ottoman territory "in case of disorder" threatening their security. The Ottoman Army (including the Ottoman Air Force) was demobilized; and all ports, railways and other strategic points were made available for use by the Allies. In the Caucasus, the Ottomans had to retreat to within the pre-war borders between the Ottoman and the Russian Empires.

The Battle of Sari Bair (Turkish: Sarı Bayır Harekâtı), also known as the August Offensive (Ağustos Taarruzları), represented the final attempt made by the British in August 1915 to seize control of the Gallipoli peninsula from the Ottoman Empire during the First World War.

At the time of the battle, the Gallipoli Campaign had raged on two fronts – Anzac and Helles – for three months since the Allied land invasion of 25 April 1915. With the Anzac front locked in a tense stalemate, the Allies had attempted to carry the offensive on the Helles battlefield – at enormous cost and for little gain. In August, the British command proposed a new operation to reinvigorate the campaign by capturing the Sari Bair ridge, the high ground that dominated the middle of the Gallipoli peninsula above the Anzac landing.

The Battle of Arras, also known as the Second Battle of Arras, was a British offensive on the Western Front during the First World War. From 9 April to 16 May 1917, British troops attacked German defences near the French city of Arras on the Western Front. The British achieved the longest advance since trench warfare had begun, surpassing the record set by the French Sixth Army on 1 July 1916 in the First day on the Somme. The British advance slowed in the next few days and the German defence recovered. The battle became a costly stalemate for both sides and by the end of the battle, the British Third Army and the First Army had suffered about 160,000 casualties and the German 6th Army about 125,000.

For much of the war, the opposing armies on the Western Front were at a stalemate, with a continuous line of trenches from the Belgian coast to the Swiss border. The Allied objective from early 1915 was to break through the German defences into the open ground beyond and engage the numerically inferior German Army (Westheer) in a war of movement. The British attack at Arras was part of the Anglo-French Nivelle Offensive, the main part of which was the Second Battle of the Aisne 50 mi (80 km) to the south. The aim of the French offensive was to break through the German defences in forty-eight hours. At Arras the Canadians were to capture Vimy Ridge, dominating the Douai Plain to the east, advance towards Cambrai and divert German reserves from the French front.
