The First Battle of Gaza was fought on 26 March 1917 during the first attempt by the Egyptian Expeditionary Force (EEF), which was a British Empire military formation, formed on 10 March 1916 under the command of General Archibald Murray from the Mediterranean Expeditionary Force and the Force in Egypt (1914–15), at the beginning of the Sinai and Palestine Campaign of the First World War. Fighting took place in and around the town of Gaza on the Mediterranean coast when infantry and mounted infantry from the Desert Column, a component of the Eastern Force, attacked the town. Late in the afternoon, on the verge of capturing Gaza, the Desert Column was withdrawn due to concerns about the approaching darkness and large Ottoman reinforcements. This British defeat was followed a few weeks later by the even more emphatic defeat of the Eastern Force at the Second Battle of Gaza in April 1917.
The Second Battle of Gaza was fought on 17–19 April 1917, following the defeat of the Egyptian Expeditionary Force (EEF) at the First Battle of Gaza in March, during the Sinai and Palestine Campaign of the First World War. Gaza was defended by the strongly entrenched Ottoman Army garrison, which had been reinforced after the first battle by substantial forces. They manned the town's defences and a line of strong redoubts which extended eastwards along the road from Gaza to Beersheba. The defenders were attacked by the Eastern Force's three infantry divisions, supported by two mounted divisions, but the strength of the defenders, their entrenchments & supporting artillery decimated the attackers.
The Third Battle of Gaza was fought on the night of 1–2 November 1917 between British and Ottoman forces during the Sinai and Palestine Campaign of World War I and came after the British Egyptian Expeditionary Force (EEF) victory at the Battle of Beersheba had ended the Stalemate in Southern Palestine. The fighting occurred at the beginning of the Southern Palestine Offensive, and, together with attacks on Hareira and Sheria on 6–7 November and the continuing Battle of Tel el Khuweilfe, which had been launched by General Edmund Allenby on 1 November, it eventually broke the Gaza-to-Beersheba line defended by the Yildirim Army Group. Despite having held this line since March 1917, the Ottoman Army was forced to evacuate Gaza and Tel el Khuweilfe during the night of 6–7 November. Only Sheria held out for most of 7 November before it too was captured.
The Battle of Megiddo was fought between 19 and 25 September 1918, on the Plain of Sharon, in front of Tulkarm, Tabsor and Arara in the Judean Hills as well as on the Esdralon Plain at Nazareth, Afulah, Beisan, Jenin and Samakh. Its name, which has been described as "perhaps misleading" since very limited fighting took place near Tel Megiddo, was chosen by British commander Edmund Allenby for its biblical and symbolic resonance.
The Sinai and Palestine campaign was part of the Middle Eastern theatre of World War I, taking place between January 1915 and October 1918. The British Empire, the French Third Republic, and the Kingdom of Italy fought alongside the Arab Revolt in opposition to the Ottoman Empire, the German Empire, and the Austro-Hungarian Empire. 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 Battle of Jerusalem occurred during the British Empire's "Jerusalem Operations" against the Ottoman Empire, in World War I, when fighting for the city developed from 17 November, continuing after the surrender until 30 December 1917, to secure the final objective of the Southern Palestine Offensive during the Sinai and Palestine Campaign of World War I. Before Jerusalem could be secured, two battles were recognised by the British as being fought in the Judean Hills to the north and east of the Hebron–Junction Station line. These were the Battle of Nebi Samwill from 17 to 24 November and the Defence of Jerusalem from 26 to 30 December 1917. They also recognised within these Jerusalem Operations, the successful second attempt on 21 and 22 December 1917 to advance across the Nahr el Auja, as the Battle of Jaffa, although Jaffa had been occupied as a consequence of the Battle of Mughar Ridge on 16 November.
The Raid on the Suez Canal, also known as Actions on the Suez Canal, took place between 26 January and 4 February 1915 when a German-led Ottoman Army force advanced from Southern Palestine to attack the British Empire-protected Suez Canal, marking the beginning of the Sinai and Palestine Campaign (1915–1918) of World War I (1914–1918).
The Yıldırım Army Group or Thunderbolt Army Group of the Ottoman Empire or Army Group F was an Army Group of the Ottoman Army during World War I. While being an Ottoman unit, it also contained the German Asia Corps.
The Battle of Sharon fought between 19 and 25 September 1918, began the set piece Battle of Megiddo half a day before the Battle of Nablus, in which large formations engaged and responded to movements by the opposition, according to pre-existing plans, in the last months of the Sinai and Palestine Campaign of World War I. The fighting took place over a wide area from the Mediterranean Sea east to the Rafat salient in the Judean Hills. Here the Egyptian Expeditionary Force (EEF) XXI Corps with the French brigade sized Détachement Français de Palestine et de Syrie attacked the Yildirim Army Group Eighth Army's XXII Corps and German Asia Corps. The Battle of Sharon extended well behind the Ottoman front lines when the Desert Mounted Corps rode through a gap in the front line across the Plain of Sharon to occupy the Esdraelon Plain. Meanwhile, during the Battle of Nablus the XX Corps attacked Nablus while Chaytor's Force held the right flank in the Jordan Valley before advancing to secure bridges and fords across the Jordan River, to continue the encirclement the defenders in the Judean Hills. Subsequently, Chaytor's Force advanced against the Fourth Army to capture Es Salt and Amman after the Second Battle of Amman.
This is the order of battle for the Battle of Megiddo (1918), the concluding engagement of the Sinai and Palestine Campaign of the First World War. The Entente's Egyptian Expeditionary Force, commanded by General Edmund Allenby and composed mainly of British, Indian, Australian and New Zealand troops, with a small French and Armenian contingent, cooperated with the Arab Northern Army, which was part of the Arab Revolt and was under the overall command of the Emir Feisal, in an all-out offensive against the Yıldırım Army Group, part of the army of the Ottoman Empire.
The Battle of Samakh was fought on 25 September 1918, during the Battle of Sharon which together with the Battle of Nablus formed the set piece Battle of Megiddo fought from 19 to 25 September 1918, in the last months of the Sinai and Palestine Campaign of the First World War. During the cavalry phase of the Battle of Sharon the Desert Mounted Corps commanded by the Australian Lieutenant General Harry Chauvel, captured the Esdraelon Plain 40–50 miles (64–80 km) behind the front line in the Judean Hills on 20 September, when the 3rd Light Horse Brigade captured Jenin. The 4th Light Horse Brigade, Australian Mounted Division was deployed guarding supply columns, and prisoners, before being ordered to attack and capture Samakh on the shore of the Sea of Gallilee. Here the Ottoman and German garrison had been ordered by the commander of the Yildirim Army Group to fight to the last man.
The Battle of Tulkarm took place on 19 September 1918, beginning of the Battle of Sharon, which along with the Battle of Nablus formed the set piece Battle of Megiddo fought between 19 and 25 September in the last months of the Sinai and Palestine Campaign of the First World War. During the infantry phase of the Battle of Sharon the British Empire 60th Division, XXI Corps attacked and captured the section of the front line nearest the Mediterranean coast under cover of an intense artillery barrage including a creeping barrage and naval gunfire. This Egyptian Expeditionary Force (EEF) victory over the entrenched Ottoman Eighth Army, composed of German and Ottoman soldiers, began the Final Offensive, ultimately resulting in the destruction of the equivalent of one Ottoman army, the retreat of what remained of two others, and the capture of many thousands of prisoners and many miles of territory from the Judean Hills to the border of modern-day Turkey. After the end of the battle of Megiddo, the Desert Mounted Corps pursued the retreating soldiers to Damascus, six days later. By the time an Armistice of Mudros was signed between the Allies and the Ottoman Empire five weeks later, Aleppo had been captured.
The Battle of Tabsor was fought on 19–20 September 1918 beginning the Battle of Sharon, which along with the Battle of Nablus formed the set piece Battle of Megiddo fought between 19 and 25 September in the last months of the Sinai and Palestine Campaign of the First World War. During the infantry phase of the Battle of Sharon the British Empire 60th Division, XXI Corps attacked and captured the section of the front line nearest the Mediterranean coast under cover of an intense artillery barrage including a creeping barrage and naval gunfire. This Egyptian Expeditionary Force (EEF) victory over the entrenched Ottoman Eighth Army, composed of German and Ottoman soldiers, began the Final Offensive, ultimately resulting in the destruction of the equivalent of one Ottoman army, the retreat of what remained of two others, and the capture of many thousands of prisoners and many miles of territory from the Judean Hills to the border of modern-day Turkey. After the end of the battle of Megiddo, the Desert Mounted Corps pursued the retreating soldiers to Damascus, six days later. By the time the Armistice of Mudros was signed between the Allies and the Ottoman Empire five weeks later, Aleppo had been captured.

The Battle of Nablus took place, together with the Battle of Sharon during the set piece Battle of Megiddo between 19 and 25 September 1918 in the last months of the Sinai and Palestine campaign of the First World War. Fighting took place in the Judean Hills where the British Empire's XX Corps attacked the Ottoman Empire's Yildirim Army Group's Seventh Army defending their line in front of Nablus. This battle was also fought on the right flank in the Jordan Valley, where Chaytor's Force attacked and captured the Jordan River crossings, before attacking the Fourth Army at Es Salt and Amman capturing many thousands of prisoners and extensive territory. The Battle of Nablus began half a day after the main Battle of Sharon, which was fought on the Mediterranean section of the front line where the XXI Corps attacked the Eighth Army defending the line in front of Tulkarm and Tabsor and the Desert Mounted Corps which rode north to capture the Esdrealon Plain. Together these two battles, known as the Battle of Megiddo, began the Final Offensive of the war in the Sinai and Palestine campaign.
The Southern Palestine offensive, began on 31 October 1917, with the Battle of Beersheba, when the British Empire's Egyptian Expeditionary Force (EEF) under the Command of Field Marshall Edmund Allenby attacked Ottoman Empire forces at the Palestinian town of Beersheba during the Sinai and Palestine Campaign, of World War I. After the capture of Beersheba, by the EEF, the Gaza to Beersheba line became increasingly weakened and, seven days later, the EEF successfully forced the Ottoman Turkish Empire's Seventh and Eighth Armies to withdraw. During the following seven days of pursuit, the Turkish forces were pushed back to Jaffa. There followed three weeks of hard fighting in the Judean Hills before Jerusalem was captured on 9 December 1917. During five and a half weeks of almost continuous offensive operations, the EEF captured 47.5 miles (76.4 km) of territory.
The Battle of Tel el Khuweilfe, part of the Southern Palestine Offensive, began on 1 November 1917, the day after the Egyptian Expeditionary Force (EEF) victory at the Battle of Beersheba during the Sinai and Palestine Campaign of World War I. After the Stalemate in Southern Palestine a series of coordinated attacks were launched by British Empire units on the Ottoman Empire's German commanded Yildirim Army Group's front line, which stretched from Gaza inland to Beersheba. During the fight for the town, the road from Beersheba to Jerusalem via Hebron, was cut just north of the town in the southern spur of the Judean Hills. Here Ottoman units strongly defended the road and the Seventh Army headquarters at Hebron.
The Capture of Wadi el Hesi and the associated Sausage Ridge, began during the evening of 7 November 1917, was fiercely fought for during 8 November and not cleared until the early hours of 9 November, at the beginning of the pursuit phase of the Southern Palestine Offensive in the Sinai and Palestine Campaign during World War I. The advancing British Empire units of the Egyptian Expeditionary Force (EEF) were held by rearguard units of the withdrawing Ottoman Empire units of the Yildirim Army Group, holding a strategically strong position to the north of Gaza.
