The Battle of el Buqqar Ridge took place on 27 October 1917, when one infantry regiment and cavalry troops of the Yildirim Army Group, attacked the 8th Mounted Brigade of the Egyptian Expeditionary Force (EEF) in the last days of the stalemate in Southern Palestine during the Sinai and Palestine campaign of World War I.

The commander of the Yildirim Army Group ordered the reconnaissance in force, which greatly outnumbered the Yeomanry in the mounted brigade, holding the outpost line. Despite a large number of casualties, one group made a slight withdrawal to subsequently hold their ground, until reinforcements arrived and the attackers withdrew. However another group of Yeomanry was overwhelmed and killed.

Four days later, two infantry and two mounted divisions launched the EEF's Southern Palestine Offensive, with the Battle of Beersheba on 31 October 1917.

During the six months stalemate following the Second Battle of Gaza, the el Buqqar ridge had been the objective of Desert Column/Desert Mounted Corps strategic marches on 5–7, 10 May and 2–3, 6–7, 14 and 24–5 June. On 19 July, the Anzac Mounted Division with the Australian Mounted Division advanced towards el Buqqar to engage an Ottoman force of two regiments of cavalry supported by infantry and four light guns, occupying the area. The 1st Light Horse Brigade attacked the force capturing 11 prisoners before the Ottoman force withdrew behind entrenchments. One of the prisoner described the attacking force as part of the Ottoman 16th Division which had been protecting a new corps commander while he made a personal reconnaissance. By the next morning the area was clear of Ottoman troops. Ottoman patrols were dispersed from el Buqqar ridge on 21 and 29 September, and on 12–14 October. The 3rd Light Horse Brigade took over from the 5th Mounted Brigade, duties of Outpost Brigade on 16 October when it was noted dawn occurred at 05:00 and dusk at 17:30.

On 18 October the day posts of 3rd Light Horse Brigade were relieved by the 5th Mounted Brigade at 09:00. The Australian Mounted Division with the 7th Mounted Brigade attached was to cover a reconnaissance by officers of the XXI Corps. By 11:50 the 7th Mounted Brigade was holding a line east of Khalasa to Ibn Saiid, the 4th Light Horse Brigade was holding Points 840, 820, 810, 790 and 770 while the 5th Mounted Brigade held points 730, 630, 550 and 300, with the Australian Mounted Divisional headquarters at Khor el Asram and the 3rd Light Horse Brigade in reserve. There was no opposition during the establishment of this line, and indeed Ottoman units "were very quiet all day more so than on any other reconnaissance." At 14:10 Ottoman infantry and cavalry were sighted at Abu Irgeig and Notts battery went into action against them, when two bell tents at Irgeig railway station and station buildings were hit. The outpost line was withdrawn at 17:30 without incident.

While the XXI Corps continued to hold the front line south of Gaza, extending eastwards from the Mediterranean Sea, the XX Corps and Desert Mounted Corps held the Wadi Ghazzeh and eastwards. On 21 October the XX Corps' 60th (London) Division defended the Shellal to Karm area with the 53rd (Welsh) Division on their left, while the front line extending into No Man's Land was defended by the Australian Mounted Division based at Tel el Fara with the Anzac Mounted Division in reserve at Abasan el Kebir. During the evening of 21 October, the 179th Brigade (60th Division) and the 2nd Light Horse Brigade (Anzac Mounted Division) moved down the Wadi Ghazzeh to Esani, to develop the water supply in preparation for the advance to Beersheba.

At 05:00 a squadron of the Royal Gloucestershire Hussars (RGH), 5th Mounted Brigade, advanced to reoccupy the el Buqqar, Point 720 to Kh Imleih and Point 630 line, when they encountered a squadron of Ottoman soldiers holding el Buqqar, with a second squadron supported by machine guns holding Point 720. Between 05:30 and 06:00 six motor cars, one with eight enemy occupants were seen at Point 720, which retired eastwards when the yeomanry appeared. The leading troop of RGH was charged from the flank, by three Ottoman troops as they approached Point 720. During the attack one man was captured when his horse fell.

The Ottoman soldiers withdrew from el Buqqar at 06:00, when threatened by a yeomanry flanking movement, and machine gun fire. By 07:00 the Ottoman squadron holding Point 720 and rifle pits, was also forced to retreat by a "well executed" converging attack made by two squadrons of Gloucester and Warwickshire Yeomanry, covered by one section of Royal Horse Artillery (RHA). The leading yeomanry troop reached Point 630, just before a squadron of Ottoman soldiers attacked. The Ottoman attackers were driven back from close quarters by yeomanry rifle and Hotchkiss machine gun fire. At the same time as these Ottoman attackers were retiring, one yeomanry troop captured Imleih ridge, but were immediately attacked by three Ottoman troops from the Wadi Hanafish. This Ottoman attack was also stopped, at "short range" by yeomanry rifle and Hotchkiss fire. Both these attacks had been covered by Ottoman high explosive and shrapnel fire, from the direction of Abu Irgeig and north of Bir Ifteis. The Ottoman units suffered at least 17 killed and wounded, while the yeomanry suffered six wounded and one missing.
