Roman Syria

Syria had been under Roman rule for seven centuries prior to the Arab Muslim conquest and had been invaded by the Sassanid Persians on a number of occasions during the 3rd, 6th and 7th centuries; it had also been subject to raids by the Sassanids' Arab allies, the Lakhmids."Syria."

. 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 didn't 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

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

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

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

, 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.

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

, 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

, 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

Next, the Muslim armies consolidated their conquest of the Levant as Shurhabil and Amr went deeper into Palestine.

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 Mediterranean coast.

, 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. According to lexicographer David ben Abraham al-Fasi (died before 1026 CE), the Muslim conquest of Palestine brought relief to the country's Jewish citizens, who had previously been barred by the Byzantines from praying on the Temple Mount.


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 (

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.

. 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 The Sasanian monarchs were the rulers of Iran after their victory against their former suzerain, the Parthian Empire, at the Battle of Hormozdgan in 224. At its height, the Sasanian Empire spanned from Turkey and Rhodes in the west to Pakistan in ...
. In 635 Yazdgerd III had sought an alliance with Heraclius, marrying the latter's daughter (or granddaughter, according to tradition) Manyanh. While Heraclius prepared for a major offense in the Levant, Yazdegerd was supposed to mount a well-coordinated counterattack on his front in Iraq, while Heraclius attacked in the Levant. However, it was not meant to be. Umar probably had intelligence of this alliance, and started peace negotiations with Yazdegerd III, apparently inviting him to join
Islam Islam (; ar, ۘالِإسلَام, , ) is an Abrahamic religions, Abrahamic Monotheism#Islam, monotheistic religion centred primarily around the Quran, a religious text considered by Muslims to be the direct word of God in Islam, God (or ...
. 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 Jabiyah ( ar, الجابية / ALA-LC: ''al-Jābiya'') was a town of political and military significance in the 6th–8th centuries. It was located between the Hawran plain and the Golan Heights. It initially served as the capital of the Ghassanids ...
. 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

in November, three months after Yarmouk, ending Sassanid control west of Persia.


Capturing Jerusalem

With the Byzantine army routed, the Muslims quickly recaptured the territory they had conquered prior to Yarmouk. Abu Ubaida held a meeting with his high commanders, including Khalid, and decided to conquer Jerusalem. The Siege of Jerusalem lasted four months, after which the city agreed to surrender, but only to Umar personally. Amr-bin al-Aas suggested that Khalid should be sent to impersonate the caliph, due to his very strong resemblance. However, Khalid was recognized and Umar had to come himself to accept the surrender of Jerusalem in April 637. Umar appointed his close advisor Ali to hold the lieutenancy of Medina. After Jerusalem, the Muslim armies broke up once again. Yazid's corps went to Damascus and then captured Beirut. Amr and Shurhabil's corps left to conquer the rest of Palestine, while Abu Ubaidah and Khalid, at the head of a 17,000-strong army, moved north to conquer Northern Syria.


Conquest of northern Syria

With Emesa already in hand, Abu Ubaidah and Khalid moved towards
Chalcis Chalcis ( ; Ancient Greek & Katharevousa: , ) or Chalkida, also spelled Halkida (Modern Greek: , ), is the chief town of the island of Euboea or Evia in Greece, situated on the Euripus Strait at its narrowest point. The name is preserved from ...
, which was strategically the most significant Byzantine fort. Through Chalcis the Byzantines would be able to guard Anatolia, Heraclius' homeland of Armenia, 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 The Battle of Hazir or ''Ma'arakah al-Haadhir'' ( ar, معركة الحاضر) took place between the Byzantine army and the Rashidun army's elite cavalry, the Mobile guard. It took place in June 637, three miles east of Qinnasrin at Al- ...
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

, 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

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

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

. 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. On the orders of Umar, Sa'd ibn Abi Waqqas, commander of the Muslim army in Iraq, sent an army under

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

and raided northern and central Anatolia. Heraclius had already abandoned all the forts between Antioch and Tartus 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.
