Role in the succession of Abu Bakr

by al-Baladhuri, the latter states "there is no truth" to the claim that Abu Ubayda was sent by Abu Bakr. Rather, the caliph "intended to send Abu ʿUbayda at the head of one of the armies, but the latter asked the caliph to relieve him of this mission". Athamina assesses that "certain allusions" in the Islamic sources offer context to the notion that Abu Ubayda, despite his participation in several expeditions under Muhammad and his high-standing among the Muslims, did not have the desire nor the necessary military experience and merit to accept the post Abu Bakr offered him. Modern research indicates that Abu Ubayda was dispatched to the Syrian front by Abu Bakr's successor, Umar, and early Muslim authors al-Baladhuri, al-Fasawi (d. 890) and

with Abu Ubayda playing a supportive role to Khalid. Umar may have sent Abu Ubayda to assume the supreme command. Several accounts in the Islamic tradition claim Abu Ubayda concealed the caliph's order from the rest of the army to avoid potentially insulting Khalid or provoking a mutiny while the Muslims were on the cusp of a major confrontation with the Byzantines. Athamina dismisses the reliability of these claims, considering them militarily illogical and meant to dramatise the change in command and emphasise Abu Ubayda's "moral superiority and unselfishness". Instead, Athamina maintains Abu Ubayda's appointment to the supreme command was made by Umar, who had kept in constant contact with Abu Ubayda through letters and emissaries, after the decisive Muslim victory at the Yarmuk. Abu Ubayda may have been chosen to lead at that time, when the Byzantine defence of Syria had taken an enormous blow, as the circumstances called for an able administrator to take the helm from a military commander like Khalid. The Islamic tradition provides a host of moral and personal reasons why Khalid was demoted in favour of Abu Ubayda, but most modern historians view these as either partially valid or literary innovations. Athamina holds Abu Ubayda was likely installed because Khalid and his large force of tribesmen from Arabia and Iraq, along with their families, presented a threat to the old-established, formerly Byzantine-allied, and militarily experienced Arab tribes of Syria, whose defection was considered vital by Umar to form a network of defences against the Byzantines. This motivated him to demote Khalid and disband his army, the remnants of which were transferred to the

and Chalcis. With the arrival of Byzantine army in the city, the peace treaty was violated. So Abu Ubadiah and Khalid marched to Emesa, and the Byzantine army that had halted Khalid's advance guard was defeated. The Muslims besieged Emesa, which was finally conquered in March 636 after a six months' siege.


Battle of Yarmouk

After capturing Emesa, the Muslims moved north to capture the whole of the northern Syria. Khalid, acting as an advance guard raided northern Syria. At Shaizer, Khalid intercepted a convoy taking provisions for Chalcis. The prisoners were interrogated and informed him about Emperor Heraclius' ambitious plan to take back Syria. They told him that an army, possibly 200,000 strong, would soon emerge to recapture their territory. After his past experience fighting the Muslim armies, Heraclius, was avoiding pitch battles with the Muslims. He planned to send massive reinforcements to all the major cities and isolate the Muslim corps from each other, and thus separately encircle and destroy the Muslim armies. In June 636, five massive armies were sent by Heraclius to recapture Syria. Khalid, sensing Heraclius's plan, feared that the Muslim armies would be isolated and destroyed. In a

. This manoeuvre turned out to be a decisive blow to the Heraclius's plan, as he did not wish engage his troops in an open battle with the Muslims, where their light cavalry could be effectively used. On Khalid's suggestion, Abu Ubayda ordered the Muslim army to withdraw from Jabiya to the plain on the

, where cavalry could be used. While the Muslim armies were gathering at Yarmouk, Khalid intercepted and routed the Byzantine advance guard. This was to ensure the safe retreat of the Muslims to Yarmouk. The Muslim armies reached Yarmouk in July 636. Around mid July, the Byzantine army arrived. The Byzantine commander in chief, Vahan, sent Christian Arab troops of the Ghassanid king,

, to check the strength of the Muslims. Khalid's mobile guard defeated and routed the Christian Arabs; this was the last action before the battle started. For the next month negotiations continued between the two armies, and Khalid went to meet Vahan in person at Byzantine camp. Meanwhile, the Muslims received reinforcements sent by Caliph Umar. Finally on 15 August, the Battle of Yarmouk was fought. It lasted for 6 days and ended in a devastating defeat for the Byzantines. The Battle of Yarmouk is considered to be a historic defeat that sealed the fate of Byzantines in the Middle East. The magnitude of defeat was so intense that Byzantine would never recover from it. It potentially left the whole of the Byzantine Empire vulnerable to Muslim attack.


Siege of Jerusalem

With the Byzantine army shattered and routed, the Muslims quickly recaptured the territory that they conquered prior to Yarmouk. Abu Ubayda held a meeting with his high command, including Khalid, to decide on future conquests. They decided to conquer Jerusalem. The Siege of Jerusalem lasted four months after which the city agreed to surrender, but only to caliph Umar in person. 'Amr ibn al-'As suggested that Khalid should be sent as if he was the caliph, because of his very strong resemblance to Umar. However, Khalid was recognized. So the surrender of Jerusalem was delayed until Umar arrived with Jerusalem formally surrendering on April 637. After capture of Jerusalem, the Muslim armies separated once again. Yazid's corps went to Damascus and captured Beirut. Amr and Shurahbil's corps went on to conquer the rest of Palestine, while Abu Ubayda and Khalid, at the head of a 17,000 strong army moved north to conquer whole of the northern Syria. Abu Ubayda sent the commanders 'Amr ibn al-'As,

, and Shurahbil ibn Hassana back to their areas to reconquer them. Most of the areas submitted without a fight. Abu Ubayda, along with Khalid, moved to northern Syria to reconquer that area with a 17,000 strong army. Khalid along with his cavalry was sent to Hazir and Abu Ubayda moved to Chalcis.


Conquest of northern Syria


Defence of Emesa

After the devastating defeat in the Battle of 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 defence of the rest of his empire, Heraclius needed to keep the Muslims occupied in Syria. Heraclius thus sought help from the Christian Arab tribes based in Jazirah and were mainly from Circesium and Hīt. The tribes mustered a large army and marched to besiege Emesa. Abu Ubayda withdrew all his forces from northern Syria to Emesa as a part of complex strategy which he devised to repel the invasion of the Christian Arab forces against Emesa. Caliph

, homeland of enemy Arab Christian tribes, in order to divert the focus of enemy concentration in Emesa. So in 638 the Muslim forces under Iyadh ibn Ghanm attacked Hīt, which they found to be well fortified. So they left some of the army to lay siege to the city, while the rest of the army went on to Circesium. Khalid was in favour of an open battle outside the fort, but Abu Ubayda sought Umar's advice, who handled the situation brilliantly. Umar sent detachments of the Muslim army from Iraq to invade Al-Jazira, homeland of the invading Christian Arabs, from three different routes. Moreover, another detachment was sent to Emesa from Iraq under Qa'qa ibn Amr, a veteran of Yarmouk who had been sent to Iraq for the

. Umar himself marched from Medina at the head of 1,000 men. The Christian Arabs, when they received the news of the Muslim invasion of their homeland, abandoned the siege and hastily withdrew to Al-Jazira. At this point Khalid and his mobile guard came out of the fort and devastated the army, attacking them from the rear.


After Emesa

Abu Ubayda sent Khalid, with his elite cavalry, the mobile guard, towards Chalcis. The fort was guarded by the Greek troops under their commander, Menas, who was reported to be of high prestige, second only to the emperor himself. Menas, diverting from conventional Byzantine tactics, decided to face Khalid and destroy the leading elements of the Muslim army before the main body could join them at Hazir, east of Chalcis. This resulted in the Battle of Hazir, which led to Umar praising Khalid's military genius. Umar is reported to have said: Abu Ubayda soon joined Khalid at the virtually impregnable fort of Chalcis, which surrendered in June 637. With this strategic victory, the territory north of Chalcis lay open to the Muslims. Khalid and Abu Ubayda continued their march northward and laid siege to Aleppo, which was captured after fierce resistance from desperate Byzantine troops in October 637. The next objective was the splendid city of Antioch, the capital of the Asian zone of the Byzantine Empire. Before marching towards Antioch, Khalid and Abu Ubayda decided to isolate the city. Accordingly, they sent detachments north to eliminate all possible Byzantine forces and captured the garrison town of

Rather, he ordered Abu Ubayda, now the governor of Syria, to consolidate his rule in Syria. At this point, Umar is reported to have said: The expedition to Anatolia and Armenia marked the end of the military career of Khalid. Due to the dismissal of Khalid from the army and a famine and plague the next year, the Muslim armies were kept from invading Anatolia.


Relief efforts during the 638 famine

During 638 Arabia fell into a severe drought, with many people perishing from hunger and epidemic diseases. A large number of people from throughout Arabia gathered in Medina as food was being rationed. Soon, Medina's food reserves declined to alarming levels. Caliph Umar wrote to the governors of his provinces requesting aid. One such letter was rushed to Abu Ubayda, who responded promptly: True to his assurance, Abu Ubayda's caravans of food supplies were the first to reach Medina, with 4,000 camels arriving loaded with food. To handle the distribution of all the food, Umar appointed Abu Ubayda to distribute the food among the thousands of people living in the outskirts of Medina. Following Abu Ubayda's generous aid and coordination of the relief efforts, Umar provided 4,000
