* Abu Ubaidah ibn al-Jarrah: Objective Emesa. Move on Tabuk route after Shurahbil.
Not knowing the precise position of the Byzantine army, Abu Bakr ordered that all corps should remain in touch with each other so that they could render assistance if the Byzantines were able to concentrate their army in any operational sector. In case the corps had to concentrate for one major battle, Abu Ubaidah was appointed Commander-in-Chief of the entire army.The Sword of Allah: Khalid bin al-Waleed, His Life and Campaigns: page no:576 by Lieutenant-General Agha Ibrahim Akram, Nat. Publishing. House, Rawalpindi (1970) .
In the first week of April 634, the Muslim forces began to move from their camps outside Medina. The first to leave was Yazid's corps, followed by Shurahbil, Abu Ubaidah and Amr, each a day's march from the other.
Abu Bakr walked for a short distance by the side of each corps commander. His parting words which he repeated to each of the corps commanders, were as follows:

As the main Byzantine defence line started from the coastal regions near Ghazahh, Yazid arrived at the Valley of Araba at about the same time as Amr bin Al Aas reached Elat. The two forward detachments sent by the Byzantine army to prevent the entry of Yazid's and Amr's corps, respectively, into Palestine, were easily defeated by them, though they did prevent the Rashidun forces from reaching their assigned objective. Abu Ubaidah and Shurhabil, on the other hand, continued their march, and by early May 634 they reached the region between Bosra and Jabiya. The Emperor Heraclius, having received intelligence of the movements of the Muslim armies from his Arab clients, began to plan countermeasures. Upon Heraclius' orders, Byzantine forces from different garrisons in the north started moving to gather at Ayjnadyn. From here they could engage Amr's corps and maneuver against the flank or rear of the rest of the Muslim corps that were in Jordan and Southern Syria. The strength of the Byzantine forces, according to rough estimates, was about 100,000. Abu Ubaidah informed the Caliph about the preparations made by the Byzantines in the third week of May 634. Because Abu Ubaida did not have experience as a commander of military forces in such major operations, especially against the powerful Roman Army, Abu Bakr decided to send Khalid ibn Walid to assume command. According to early Muslim chronicles, Abu Bakr said, "By Allah, I shall destroy the Romans and the friends of Satan with Khalid Ibn Al Walid."
Khalid immediately set out for Syria from Al-Hirah, in

, in early June, taking with him half his army, about 8000 strong. There were two routes towards Syria from Iraq: one was via Daumat-ul-Jandal, and the other was through Mesopotamia, passing through Raqqa. The Muslim armies in Syria were in need of urgent reinforcement, so Khalid avoided the conventional route to Syria via Daumat ul Jandal, as it was the longer route, and would take weeks to reach Syria. Khalid avoided the Mesopotamian route because of the presence of Roman garrisons there and in Northern Syria. To engage them at a time when Muslim armies were being outflanked in Syria was not a wise idea. Khalid selected a shorter route to Syria, an unconventional route passing through the Syrian Desert. It is recorded that his soldiers marched for two days without a single drop of water, before reaching a predetermined water source at an

through a mountain pass which is now known as Sanita-al-Uqab (Uqab Pass) after the name of Khalid's army standard. From here he moved away from Damascus, towards Bosra, the capital of the Ghassanids. He ordered other Muslim commanders to concentrate their armies, still near the Syrian-Arabian border, at Bosra. At Maraj-al-Rahab, Khalid defeated a Ghassanid army in a quick battle, called the Battle of Marj-al-Rahit. Meanwhile, Abu Ubaida ibn al-Jarrah, the supreme commander of the Muslim armies in Syria, had ordered Shurhabil ibn Hasana to attack Bosra. The latter laid siege to Bosra with his small army of 4000. The Roman and Ghassanid Arab garrison, realizing that this might be the advance guard of the larger Muslim army to come, sallied out of the fortified city and attacked Shurhabil, surrounding him from all sides; however, Khalid reached the arena with his cavalry and saved Shurhabil. The combined forces of Khalid, Shurhabil, and Abu Ubaidah then resumed the siege of Bosra, which surrendered some time in mid-July 634 CE, effectively ending the Ghassanid Dynasty.
Here Khalid took over the command of the Muslim armies in Syria from Abu Ubaidah, according to the instructions of the Caliph. Massive Byzantine armies were concentrating at Ajnadayn to push the invading armies back to the desert. Early Muslim sources claim the Byzantine strength to have been 90,000, although most modern historians doubt the figures, yet consider this battle to be the key to breaking Byzantine power in Syria. On Khalid's instructions, all Muslim corps concentrated at Ajnadayn, where they won a decisive battle against the Byzantines on 30 July.
This defeat left Syria vulnerable to the Muslim invaders. Khalid decided to capture Damascus, the Byzantine stronghold. At Damascus, Thomas, son-in-law of Emperor Heraclius, was in charge. Having received intelligence of Khalid's march towards Damascus, he prepared for its defence, writing to Emperor Heraclius in Emesa for reinforcements. Moreover, Thomas, in order to get more time for preparation of a siege, sent armies to delay or, if possible, halt Khalid's march to Damascus. One of these armies was defeated at the Battle of Yaqusa in mid-August near Lake Tiberias, 145 kilometres (90 mi) from Damascus. Another was defeated in the Battle of Maraj as Saffer on 19 August. These engagements had the desired effect, delaying Khalid long enough to prepare for a siege. However, by the time Heraclius' reinforcements had reached the city Khalid had begun his siege, having reached Damascus on 20 August. To isolate the city from the rest of the region Khalid placed detachments south on the road to Palestine and in the north at the Damascus-Emesa route, and several other smaller detachments on routes towards Damascus. Heraclius' reinforcements were intercepted and routed at the Battle of Sanita-al-Uqab, 30 kilometres (20 mi) from Damascus. Khalid's forces withstood three Roman sallies that tried to break the siege. Khalid finally attacked and conquered Damascus on 18 September after 30 days, although, according to some sources, the siege had in fact lasted for four or six months. Heraclius, having received the news of the fall of Damascus, left for Antioch from Emesa. The citizens were granted peace on the promise of annual tribute and the Byzantine army was given three days to go as far as they could. After three days, Khalid took a cavalry force, caught up to the Romans using an unknown shortcut, and attacked them at the Battle of Maraj-al-Debaj, north of Damascus.
Conquest under Caliph Umar
Dismissal of Khalid from command
On 22 August, Abu Bakr, the first caliph, died, having made Umar his successor. Umar's first move was to relieve Khalid from command and appoint Abu Ubaidah ibn al-Jarrah as the new commander-in-chief of the Islamic army. Abu Ubaidah got the letter memorializing this during the siege, but he delayed the announcement until the city had been conquered. Later on, Khalid pledged his loyalty to the new Caliph and continued to serve as an ordinary commander under Abu Ubaidah. He is reported to have said, "If Abu Bakr is dead and Umar is Caliph, then we listen and obey."
Abu Ubaidah moved more slowly and steadily, which had a concomitant effect on military operations in Syria. Abu Ubaidah, being an admirer of Khalid, made him commander of the cavalry and relied heavily on his advice during the whole campaign.
Conquest of the Central Levant
Soon after the appointment of Abu-Ubaidah as commander in chief, he sent a small detachment to the annual fair held at Abu-al-Quds, modern day Ablah, near Zahlé east of Beirut. There was a Byzantine and Christian Arab garrison nearby, but the size of the garrison was miscalculated by the Muslim informants. The garrison quickly encircled the small Muslim detachment, but before it was completely destroyed, Khalid came to the rescue of the Muslim army. Abu Ubaidah, having received new intelligence, had sent Khalid. Khalid reached the battlefield and defeated the garrison on 15 October and returned with tons of looted booty from the fair and hundreds of Roman prisoners.
By capturing central Syria, the Muslims had given a decisive blow to the Byzantines. The communication between Northern Syria and Palestine was now cut off. Abu Ubaidah decided to march to Fahl, which is about 150 metres (500 ft) below sea level, where a strong Byzantine garrison and survivors of the Battle of Ajnadayn were present. The region was crucial because from here the Byzantine army could strike eastwards and cut Muslim communications with Arabia. Moreover, with this large garrison at their rear Palestine could not be invaded.
Khalid, commanding the advance guard, reached Fahl first and found that the Byzantines had flooded the plains by blocking the River Jordan. The Byzantine army was eventually defeated at the Battle of Fahl on 23 January 635.
Conquest of Palestine (634–641)
Next, the Muslim armies consolidated their conquest of the Levant as Shurhabil and Amr went deeper into Palestine. Bet She'an surrendered after a little resistance followed by the surrender of Tiberias in February. Umar, after having learned of the position and strength of the Byzantine army in Palestine, wrote detailed instructions to his corps commanders there and ordered Yazid to capture the

, Caesarea and Ashkelon, were in Muslim hands. On the orders of Umar, Yazid next besieged Caesarea, which, barring a suspension around the time of the Battle of Yarmouk, lasted until the port fell in 640.
Battles for Emesa and Second Battle of Damascus
After the battle, which proved to be the key to Palestine and Jordan, the Muslim armies split up. Shurhabil and Amr's corps moved south to capture Palestine, while Abu Ubaidah and Khalid, with a relatively larger corps, moved north to conquer Northern Syria.
While the Muslims were occupied at Fahl, Heraclius, sensing an opportunity, quickly sent an army under General Theodras to recapture Damascus, where a small Muslim garrison was left. Shortly thereafter, the Muslims, having just won the Battle of Fahl, were on their way to Emesa. In the meantime, the Byzantine army split in two, one deployed at Maraj al Rome ( Beqaa Valley) led by Schinos; the other, commanded by Theodras, stationed to the west of Damascus ( Al-Sabboura region).
During the night, Theodras advanced to Damascus to launch a surprise attack. Khalid's spy informed him about the move and Khalid, having received permission from Abu Ubaidah, galloped towards Damascus with his mobile guard. While Abu Ubaidah fought and defeated the Roman army in the Battle of Marj ar-Rum, Khalid moved to

with his cavalry and attacked and defeated Theodras there. A week later, Abu Ubaida himself moved towards Heliopolis, where the great Temple of Jupiter stood.
In May 636, Heliopolis surrendered to the Muslims after little resistance and agreed to pay tribute. Abu Ubaidah sent Khalid straight towards Emesa.
Emesa and

offered a peace treaty for a year. Abu Ubaidah accepted the offer and, rather than invading districts of Emesa and Chalcis, he consolidated his rule in conquered land and captured Hamah, and Maarrat al-Nu'man. Having mustered sizeable armies at Antioch, Heraclius sent them to reinforce strategically important areas of Northern Syria, like Emesa and Chalcis. The Byzantine reinforcement of Emesa violated the treaty, and Abu Ubaidah and Khalid accordingly marched there. A Byzantine army that halted Khalid's advance guard was defeated. The Muslims besieged Emesa which was finally conquered in March 636 CE after two months.
Battle of Yarmouk
After capturing Emesa, Khalid moved north to capture Northern Syria, using his cavalry as an advance guard and raiding force. At Shaizar, Khalid intercepted a convoy taking provisions for Chalcis. The prisoners were interrogated and informed him about Emperor Heraclius' ambitious plan to take back Syria with an army possibly two hundred thousand (200,000) strong. Khalid immediately ended the raid.
After his past experiences, Heraclius now avoided pitched battle with the Muslim army. His plans were to send massive reinforcements to all the major cities, isolate the Muslim corps from each other, and then separately encircle and destroy the Muslim armies.
Part of his plan was to coordinate his attacks with those of Yazdgerd III, the Sassanid emperor. While Heraclius prepared for a major offense in the Levant, Yazdegerd was supposed to mount a well-coordinated counterattack on his front in

. When Heraclius launched his offensive in May 636, Yazdegerd, probably owing to the exhaustion of his government, could not coordinate with the Heraclian offensive, frustrating the plan.
Five massive armies were launched in June to recapture Syria. Khalid, having grasped Heraclius' plan, feared that the Muslim armies would become isolated and then destroyed piecemeal. He thus suggested to Abu Ubaidah in a council of war that he consolidate all the Muslim armies at one place to force a decisive battle with the Byzantines. Abu Ubaidah agreed, and concentrated them at Jabiya. This maneuver delivered a decisive blow to Heraclius' plan, since the latter did not wish to engage his troops in open battle with the Muslim light cavalry. From Jabiya, again on Khalid's suggestion, Abu Ubaidah ordered the Muslim troops to withdraw to the Plain of the Yarmouk River, where the cavalry could be used effectively. While the Muslim armies were gathering at Yarmouk, Khalid intercepted and routed the Byzantine advance guard, ensuring a safe path of retreat.
The Muslim armies reached the plain in July. A week or two later, around mid-July, the Byzantine army arrived. The Byzantine commander-in-chief, Vahan, sent Ghassanid forces, under their king, Jabala, to gauge the Muslim strength. Khalid's mobile guard defeated and routed them, the last action before the battle started. For one month negotiations continued between the two armies and Khalid went to meet Vahan in person at the Byzantine camp. Meanwhile, Muslim reinforcements arrived from Umar.
Abu Ubaidah, in another council of war, transferred field command of the Muslim army to Khalid. Finally, on 15 August, the Battle of Yarmouk was fought, lasting six days and ending in a major defeat for the Byzantines. This battle and subsequent clean-up engagements forever ended Byzantine domination of the Levant.
Meanwhile, Umar occupied Yazdegerd III in a grand deception. Yazdegerd III lost his army at the Battle of Qadisiyyah in November, three months after Yarmouk, ending Sassanid control west of

, and the regional capital, Antioch. Abu Ubaidah sent Khalid with his mobile guard towards Chalcis. The virtually impregnable fort was guarded by Greek troops under Menas, reportedly second in prestige only to the Emperor himself. Menas, diverting from conventional Byzantine tactics, decided to face Khalid and destroy the leading elements of Muslim army before the main body could join them at Hazir 5 kilometres (3 mi) east of Chalcis. The resulting Battle of Hazir even reportedly forced Umar to praise Khalid's military genius, saying, "Khalid is truly the commander. May Allah have mercy upon Abu Bakr. He was a better judge of men than I have been."
Abu Ubaidah soon joined Khalid at Chalcis, which surrendered some time in June. With this strategic victory, the territory north of Chalcis lay open to the Muslims. Khalid and Abu Ubaidah continued their march northward and laid siege to Aleppo, which was captured after fierce resistance from desperate Byzantine troops in October. Before marching towards Antioch, Khalid and Abu Ubaidah decided to isolate the city from Anatolia. They accordingly sent detachments north to eliminate all possible Byzantine forces and captured the garrison town of Azaz, 50 kilometres (30 mi) from Aleppo; from there Muslims attacked Antioch from the eastern side, resulting in the Battle of Iron bridge. The Byzantine army, composed of the survivors of Yarmouk and other Syrian campaigns, was defeated, retreating to Antioch, whereupon the Muslims besieged the city. Having little hope of help from the Emperor, Antioch surrendered on 30 October, on the condition that all Byzantine troops would be given safe passage to Constantinople. Abu Ubaidah sent Khalid towards the north and he himself marched to the south and captured

. On the way, he had a narrow escape when Khalid, who had just captured Marash, was heading south towards Manbij. Heraclius hastily took the mountainous path and, on passing through the Cilician gates, is reported to have said, "Farewell, a long farewell to Syria, my fair province. Thou art an infidel's (enemy's) now. Peace be with you, O, Syria – what a beautiful land you will be for the enemy hands."
Byzantine counterattack
After the devastating defeat at Yarmouk, the remainder of the Byzantine empire was left vulnerable. With few military resources left, it was no longer in a position to attempt a military comeback in Syria. To gain time to prepare a defense of the rest of his empire, Heraclius needed the Muslims occupied in Syria. He thus sought help from the Christians (some of whom were Arabs) of Jazirah, mainly from Circesium and Hīt, who mustered a large army and marched against Emesa, Abu Ubaidah's headquarters. Abu Ubaidah withdrew all his forces from northern Syria to Emesa, and the Christians laid in a siege. Khalid was in favor of an open battle outside the fort, but Abu Ubaidah referred the matter to Umar, who sent a detachment from Iraq to invade Jazirah from three different routes. Another detachment was sent to Emesa from Iraq under Qa’qa ibn Amr, a veteran of Yarmouk, who had originally been sent to Iraq for the Battle of al-Qādisiyyah. Umar himself marched from Medina with 1,000 men.
In 638, Muslims attacked Hīt, which they found to be well fortified; thus, they left a fraction of the army to impose a siege on the city, while the rest went after Circesium. When the Christians received the news of the Muslim invasion of their homeland, they abandoned the siege and hastily withdrew there. At this point Khalid and his mobile guard came out of the fort and devastated their army by attacking them from the rear. In late 638, Ibn Walid also captured Germanicia.
On the orders of Umar, Sa'd ibn Abi Waqqas, commander of the Muslim army in Iraq, sent an army under Iyad ibn Ghanm to conquer the region between the Tigris and the Euphrates up to Urfa. In 639–640, Raqqa fell into Muslim hands, followed by most of Jazirah, the last base of the Eastern Roman Empire in the region, which surrendered peacefully and agreed to pay Jizya.
Campaigns in Armenia and Anatolia
The conquest of Jazirah was completed by 640 CE, after which Abu Ubaidah sent Khalid and Iyad ibn Ghanm (conqueror of Jazirah) to invade Byzantine territory north of there. They marched independently and captured Edessa, Amida, Melitene (Malatya) and the whole of Armenia up to Ararat and raided northern and central Anatolia. Heraclius had already abandoned all the forts between Antioch and

to create a buffer zone between the Muslim controlled areas and Anatolia.
Umar then called a halt to the expedition and ordered Abu Ubaidah, now governor of Syria, to consolidate his rule there. This decision can be explained by the dismissal of Khalid from the army, which ended his military career, and a drought followed by a plague the year after.
