The Asian and Pacific theatre of World War I consisted of various military engagements that took place on the Asian continent and on Pacific islands. They include naval battles, the Allied conquest of German colonial possessions in the Pacific Ocean and China, and an anti-Russian rebellion in Russian Turkestan. The most significant military action was the careful and well-executed Siege of Tsingtao in China, but smaller actions were also fought at Bita Paka and Toma in German New Guinea.

The Charge at Khan Ayash occurred on 2 October 1918 about 17 miles (27 km) north of Damascus after the pursuit to, and capture of Damascus, which followed the decisive Egyptian Expeditionary Force victory at the Battle of Megiddo on 25 September during the Sinai and Palestine Campaign of World War I. After Damascus had been encircled by Desert Mounted Corps on 30 September, the 3rd Light Horse Brigade advanced through the city on 1 October to charge and capture remnants of the Ottoman Yildirim Army Group withdrawing along the road north to Rayak and Homs.

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, the Russians and the French from among the Allied Powers. There were five main campaigns: the Sinai and Palestine Campaign, the Mesopotamian Campaign, the Caucasus Campaign, the Persian Campaign, and the Gallipoli Campaign. There were also several minor campaigns: Arab Campaign, and South Arabia Campaign.

The Battle of Mughar Ridge, officially known by the British as the Action of El Mughar, took place on 13 November 1917 during the Pursuit phase of the Southern Palestine Offensive of the Sinai and Palestine Campaign in the First World War. Fighting between the advancing Egyptian Expeditionary Force (EEF) and the retreating Yildirim Army Group, occurred after the Battle of Beersheba and the Third Battle of Gaza. Operations occurred over an extensive area north of the Gaza to Beersheba line and west of the road from Beersheba to Jerusalem via Hebron.

The Raid on Nekhl was the second of three battles by British forces to recapture the Sinai Peninsula during the Sinai and Palestine Campaign of World War I. Egyptian Expeditionary Force (EEF) mounted forces travelled into the centre of the Sinai Peninsula to attack and push the last Ottoman Army garrisons back into Palestine.

Conflicts took place in North Africa during World War I (1914–1918), between the Entente and the Central powers. The Senussi of Libya sided with the Ottoman Empire against the British Empire and the Kingdom of Italy. On 14 November 1914, the Ottoman Sultan proclaimed Jihad and sought to create a diversion to draw British troops from the Sinai and Palestine Campaign. The Italian state wished to preserve the gains made in the Italo-Turkish War. The Senussi Campaign took place in north Africa, from 23 November 1915 – February 1917.

The Stalemate in Southern Palestine was a six month standoff between the British Egyptian Expeditionary Force (EEF) and the Ottoman Army in World War I. The two hostile forces faced each other along the Gaza to Beersheba line during the Sinai and Palestine Campaign, with neither side able to force its opponent to withdraw. The stalemate began in April 1917 with the defeat of the EEF by the Ottoman Army at the Second Battle of Gaza and lasted until the EEF offensive began with the Battle of Beersheba on 31 October 1917.

The Charge at Sheria took place on 7 November 1917 during the Battle of Hareira and Sheria when the 11th and 12th Light Horse Regiments charged a Yildirim Army Group rearguard in support of an attack by the 60th (London) Division during the Southern Palestine Offensive of the Sinai and Palestine Campaign in World War I.

The Sinai and Palestine campaign of the Middle Eastern theatre of World War I was fought by the Arab Revolt and the British Empire, against the Ottoman Empire and its Imperial German allies. It started with an Ottoman attempt at raiding the Suez Canal in 1915, and ended with the Armistice of Mudros in 1918, leading to the cession of Ottoman Syria.

The Western Front was the main theatre of war during the First World War. Following the outbreak of war in August 1914, the German Army opened the Western Front by invading Luxembourg and Belgium, then gaining military control of important industrial regions in France. The German advance was halted with the Battle of the Marne. Following the Race to the Sea, both sides dug in along a meandering line of fortified trenches, stretching from the North Sea to the Swiss frontier with France, which changed little except during early 1917 and in 1918.
