The XX Corps was an army corps of the British Army during World War I.
The Corps was formed in Palestine in June 1917 under Lieutenant General Philip Chetwode. [1] Following the British failure in the Second Battle of Gaza, the Egyptian Expeditionary Force underwent a major rearrangement with the appointment of General Edmund Allenby as the new Commander-in-Chief. The infantry component of the force was divided into two corps; XX Corps and XXI Corps.
The corps initially comprised four infantry divisions: [2]
The XX Corps first saw action in the Beersheba phase of the Third Battle of Gaza on 31 October 1917. [2] The 60th and 74th Divisions captured Turkish outposts west of the town but were not involved in the final assault. Following Beersheba on 6 November, the corps made a frontal assault against the Turkish fortifications in the vicinity of Sheria where the 10th, 60th and 74th Divisions succeeded in breaking through. The 10th Division captured the Hareira Redoubt on 7 November [3] and the 60th Division advanced on Huj in support of the Australian Mounted Division's effort to cut off the retreating Turkish army. [4]
During the Battle of Megiddo the formation was: [5]
Commanders included:
The Desert Mounted Corps was an army corps of the British Army during the First World War, of three mounted divisions renamed in August 1917 by General Edmund Allenby, from Desert Column. These divisions which served in the Sinai and Palestine Campaign had been formed by Australian light horse, British yeomanry, and New Zealand mounted rifles brigades, supported by horse artillery, infantry and support troops. They were later joined by Indian cavalry and a small French cavalry detachment.
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 Late in the afternoon, on the verge of capturing Gaza, the Desert Column was withdrawn due to concerns about the approaching darkness and large Ottoman reinforcements.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 Battle of Beersheba was fought on 31 October 1917, when the British Empire's Egyptian Expeditionary Force (EEF) attacked and captured the Ottoman Empire's Yildirim Army Group garrison at Beersheba, beginning the Southern Palestine Offensive of the Sinai and Palestine campaign of World War I.
The 74th (Yeomanry) Division was a Territorial Force infantry division formed in Palestine in early 1917 from three dismounted yeomanry brigades. It served in the Sinai and Palestine Campaign of the First World War, mostly as part of XX Corps. In May 1918 it was sent to the Western Front where it remained until the end of the war.
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.
Field Marshal Philip Walhouse Chetwode, 1st Baron Chetwode, 7th Baronet of Oakley,, was a senior British Army officer. He saw action during the Second Boer War, during which he was present at the Siege of Ladysmith in December 1899. He saw action again during World War I on the Western Front, taking part in the First Battle of Ypres, and then in the Sinai and Palestine campaign during which he led his corps at the First Battle of Gaza in March 1917, at the Battle of Beersheba in October 1917 and the Battle of Jerusalem in November 1917.
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 XXI Corps was an Army Corps of the British Army during World War I. The Corps was formed in Palestine in August 1917 under the command of Lieutenant General Edward Bulfin. It formed part of the Egyptian Expeditionary Force (EEF) and served in the Sinai and Palestine Campaign. At the Battle of Sharon it fought what has been described as 'one of the most overwhelmingly successful operations of the war' and 'a precursor to the modern Blitzkrieg.' It then carried out remarkable march up the coast of modern-day Lebanon as the war came to an end.
The Capture of Jericho occurred between 19 and 21 February 1918 to the east of Jerusalem beginning the Occupation of the Jordan Valley during the Sinai and Palestine Campaign of the First World War. Fighting took place in an area bordered by the Bethlehem–Nablus road in the west, the Jordan River in the east, and north of a line from Jerusalem to the Dead Sea. Here a British Empire force attacked Ottoman positions, forcing them back to Jericho and eventually across the Jordan River.
The Desert Column was a First World War British Empire army corps which operated in the Sinai and Palestine Campaign from 22 December 1916. The Column was commanded by Lieutenant General Philip W. Chetwode and formed part of Eastern Force. When Chetwode took command of Eastern Force after the Second Battle of Gaza, Harry Chauvel took command and oversaw the expansion of the column to three divisions.
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 Hareira and Sheria was fought on 6–7 November 1917 when the Egyptian Expeditionary Force attacked and captured the Yildirim Army Group's defensive systems protecting Hareira and Sheria in the centre of the Gaza to Beersheba line, during the Southern Palestine Offensive of the Sinai and Palestine Campaign in World War I.
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 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 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.
The 155th Pioneers was a pioneer regiment of the British Indian Army. It was formed in Mesopotamia and Palestine in May and June 1918, saw service in the Sinai and Palestine Campaign in the First World War, and was disbanded in 1920.
