Yildirim Army Group withdraw from Rayak After an RAF attack on Rayak, Liman von Sanders withdrew the Rayak force on 2 October sending most of his troops including Colonel von Oppen's Asia Corps under the command of Mustapha Kemal to Aleppo, to prepare a defence. This force retreated to Homs via Ba'albek on their way to Aleppo; the first place offering the possibility of a strong defence, while the remnant Fourth Army prepared a rearguard defence of Homs.
4th and 5th Cavalry Divisions' pursuit The country north from Damascus, with its grand mountains and fertile valley and slopes, was described as being more beautiful than that to the south of the city. The
Nahr el Litani or Leontes river flowing south between the parallel ranges of the Lebanon and the Anti-Lebanon enters the sea between Tyre and Sidon. Along the valley cattle, sheep and goats grazed and barley and wheat were grown with oats in the north. The only breaks in the north-south Lebanon and Anti-Lebanon mountain ranges occur from Damascus to Beirut and from Homs to Tripoli. On 5 October the advance north was resumed although supply would be difficult. Allenby anticipated capturing the ports of Beirut and Tripoli, which would improve supplying rations to Desert Mounted Corps. "Nevertheless his decision [to continue the pursuit] was born of rare ambition and resolution." It would be a "bold move" as the British Empire troops would be well beyond range of support from the rest of the EEF. Allenby briefed Chauvel on his Aleppo campaign plans at Chauvel's new headquarters in a former Yilderim Army Group building in the south–western suburbs during his day-trip to Damascus on 3 October. The Australian Mounted Division commanded by H. W. Hodgson was to garrison Damascus, while the 5th Cavalry Division commanded by Major General
Henry Macandrew and the 4th Cavalry Division commanded by Major General
G. de S. Barrow advanced to Rayak northwest of Damascus, to establish a new forward line to stretch east to Beirut. Heavy Artillery Group crossing the Leontes River during their march to Aleppo from Tripoli in February 1919 The 4th and 5th Cavalry Divisions left Damascus together on 5 October without wheeled transport and guns which rejoined at
Khan Maysalun from Damascus and above sea-level after passing through the city. The Sherwood Rangers regiment which had been on the lines of communication at Kuneitra rejoined the 14th Cavalry Brigade, 5th Cavalry Division. The 12th Light Armoured Motor Battery and the 7th Light Car Patrol also joined the divisions. From Khan Meizelun the 4th Cavalry Division moved to Zebdani on the railway between Damascus and Rayak while the 5th Cavalry Division moved towards Rayak by the main road through Shtora. During the night of 5/6 October, a report was received that the Ottomans had withdrawn from Rayak. Here the remains of 32 German aircraft were found, "including some of the latest type, [which] had been either abandoned or burnt by the enemy." Military equipment, engineers' stores, several locomotives and rail trucks were captured at Rayak. The 14th Cavalry brigade also captured 177 prisoners and some guns when they occupied Zahle a few miles north of Rayak, also without opposition. Desert Mounted Corps numbers, however dropped dramatically each day as increasing numbers of men became ill, weakening the corps' effectiveness. On 14 October, the 4th Cavalry Division moved to Shtora , in the Rayak Valley. Allenby and Chauvel spent some days visiting the troopers while the division was at Ba'albek with a brigade at Lebwe. According to Maunsell, "the Middlesex Yeomanry were down to twenty-six officers and men, while Jacob's Horse had an average of twenty-five men per squadron only. The difficulty of looking after the horses can be imagined and we had to have numbers of Turk prisoners to help." But Falls notes that it was unable to do so "still less to support the 5th in case of need at Aleppo." Thus, Maunsell writes, "the Great War, so far as the 4th Cavalry Division was concerned, was ended."
Reorganisation of 5th Cavalry Division At Baalbek, General MacAndrew reorganised his 5th Cavalry Division into two columns; the lead unit Column "A" consisted of the divisional headquarters, 24 cars in three batteries of armoured cars, and three light car patrols armed with machine guns, supported by the
15th Imperial Service Cavalry Brigade (less the
Hyderabad Lancers on the line of communications). The country was "fairly flat" with a good surface for the cars to negotiate and with their heavy machine–gun fire they were a strong raiding force.
5th Cavalry Division and Sherifial Force pursuit The 5th Cavalry Division had not been so badly affected by sickness and was able to continue the pursuit as it had garrisoned Afulah and Nazareth well away from the mosquito infested areas along the Jordan River. Nor were they involved in the fighting at Jisr Benat Yakub, when they were in reserve to the Australian Mounted Division. Allenby now ordered the 5th Cavalry Division to advance to Homs while the 4th Cavalry Division, which barely had enough men to carry out normal camp duties, remained to garrison the Zahle-Rayak-Baalbek area. "B" Battery HAC and armoured cars, with the remainder of the division in the rear column, a day's march behind. The leading column of the cavalry reached Lebwe on 13 October, El Qa'a on 14 October and El Quseir on 15 October a total of passing through the fertile plain of the Nahr el Litani valley where bread, meat and grain was easily requisitioned at each place. overlooking Homs The 5th Cavalry Division's fighting strength of 2,500 included the strongest column of armoured cars so far employed in the theatre. These included the 2nd, 11th and 12th Light Armoured Motor Batteries and the 1st (Australian), 2nd and 7th Light Car Patrols. The 4th Cavalry Division was to advance to Homs in support.
Occupation of Hama The remaining soldiers in the 48th Infantry Regiment which had been part of the 16th Division, Asia Corps (formerly Eighth Army) at the beginning of the Battle of Megiddo on 19 September, set up a rearguard at
Hama. However, the rearguard was eventually forced to withdraw on 19 October as Desert Mounted Corps approached. The pursuit was to be reinforced by Feisal, who "promised to despatch 1,500 troops from Homs under Sherif Nasir, and hoped to raise some thousands more of local Arabs on his march." The retreating Yildirim Army Group had blown up the bridge over the Orontes River at Er Rastan north of Homs. The 15th Imperial Service Cavalry Brigade (5th Cavalry Division) with the 5th Field Squadron R. E. arrived to repair the span of the bridge on 19 October. Repairs were complete by 06:00 on 21 October and by that afternoon the 5th Cavalry Division's headquarters, the 15th Imperial Service Cavalry Brigade (less the Hyderabad Lancers on the lines of communication south of Damascus) and the armoured cars arrived at Hama.
Pursuit continues towards Aleppo Column "A" of Macandrew's 5th Cavalry Division continued the pursuit on 21 October to reach north of Hama. The armoured cars conducted an extended reconnaissance on 22 October to reach Ma'arit el Na'aman, away at noon without sighting the enemy. They continued their journey another towards Aleppo to arrive near
Khan Sebil, north of Hama and halfway to Aleppo, at 14:30. A running battle was fought between the mobile forces of one German armoured car and six lorries and the 5th Cavalry Division's armoured cars. The 5th Cavalry Division's armoured cars eventually reached Zor Defai from Hama and only south of Aleppo, in the late afternoon of 22 October before they turned back to just north of Khan Seraikin, where they bivouacked at
Seraqab from Khan Sebil and from Aleppo.

Bristol Fighters of
No. 1 Squadron moved their base forward from
Ramleh to Haifa and by mid October were required to patrol and reconnoitre an exceptionally wide area of country, sometimes between , flying over Rayak, Homs, Beirut, Tripoli, Hama, Aleppo, Killis and Alexandretta in support of the pursuit by the 15th Imperial Service Cavalry Brigade and the armoured cars of Desert Mounted Corps. They conducted aerial reconnaissances and bombing raids, bombing the German aerodromes at Rayak on 2 October where 32 German machines, were seen three hours later by two Bristol Fighters to have been abandoned or burnt. On 9 October five Bristol Fighters attacked with bombs and machine–guns, troops getting on trains at Homs railway station. A similar attack took place on 16 October when trains at Hama station were the target. On 19 October the first German aircraft seen in the air since the aerial fighting over Deraa, a
D.F.W. two–seater was forced to land. The aircraft was destroyed on the ground by firing a
Very light into the aircraft after the German pilot and observer had moved to safety. The Mouslimie railway junction of the Baghdad and Palestine railways north of Aleppo, was bombed on 23 October and at noon five Australian aircraft bombed the city and Aleppo railway station. == Sherifial Force captures Aleppo ==
