Abu Bakr's confidence grew, and once Khalid established his stronghold in Iraq, Abu Bakr issued a call to arms for the invasion of Syria in February 634.

The Muslim armies, however, soon proved to be too small to handle the Byzantine response, and their commanders called for reinforcements.

However, once concentrated at Jabiyah, the Muslims were subject to raids from pro-Byzantine Ghassanid forces. Encamping in the region was also precarious as a strong Byzantine force was garrisoned in Caeseara and could attack the Muslim rear while they were held in front by the Byzantine army. On Khalid's advice the Muslim forces retreated to Dara’ah (or Dara) and Dayr Ayyub, covering the gap between the Yarmuk Gorges and the Harra lava plains, and established a line of camps in the eastern part of the plain of Yarmuk. This was a strong defensive position, and the maneuverers brought the Muslims and Byzantines into a decisive battle, which the latter had tried to avoid. During the maneuvers, there were no engagements except for a minor skirmish between Khalid's elite light cavalry and the Byzantine advance guard.

hills although the hills were outside the actual field of battle. Strategically, there was only one prominence in the battlefield: a elevation known as ''Tel al Jumm'a'', and for the Muslim troops concentrated there, the hill gave a good view of the plain of Yarmuk. The ravine on the west of the battlefield was accessible at a few places in 636 AD, and had one main crossing: a Roman bridge (''Jisr-ur-Ruqqad'') near ''Ain Dhakar'' Logistically, the Yarmuk plain had enough water supplies and pastures to sustain both armies. The plain was excellent for cavalry maneuvers.
Troop deployment
Most early accounts place the size of the Muslim forces between 36,000 and 40,000 and the number of Byzantine forces between 60,000 and 70,000 (This number has been estimated by taking into account the logistical situation of the Empire and with the view that they could never have mustered such troops when the Empire was at its apex but especially not with the especially weak and exhausted realm of 628 onwards). Modern estimates for the sizes of the respective armies vary: some estimates for the Byzantine army are between 80,000 and 150,000, while other estimates are 15,000 to 20,000. Estimates for the

are between 25,000 and 40,000. Original accounts are mostly from Arab sources, generally agreeing that the Byzantine army and their allies outnumbered the Muslim Arabs by a 2 to 1. The only early Byzantine source is Theophanes, who wrote a century later. Accounts of the battle vary, some stating it lasted a day, others more than a day.
Rashidun army
During a council of war, the command of the Muslim army was transferred to Khalid by Abu Ubaidah, Commander in Chief of the Muslim army.
After taking command, Khalid reorganized the army into 36 infantry regiments and four cavalry regiments, with his cavalry elite, the mobile guard, held in reserve. The army was organised in the ''Tabi'a'' formation, a tight, defensive infantry formation.
The army was lined up on a front of , facing west, with its left flank lying south on the Yarmuk River a mile before the ravines of ''Wadi al Allan'' began. The army's right flank was on the Jabiyah road in the north across the heights of ''Tel al Jumm'a'', with substantial gaps between the divisions so that their frontage would match that of the Byzantine battle line at . The centre of the army was under the command of Abu Ubaidah ibn al-Jarrah (left centre) and Shurahbil bin Hasana (right centre). The left wing was under the command of Yazid and the right wing was under Amr ibn al-A's.
The centre, left and right wings were given cavalry regiments, to be used as a reserve for a counterattack if they were pushed back by the Byzantines. Behind the centre stood the

under the personal command of Khalid. If Khalid was too occupied in leading the general army, Dharar ibn al-Azwar would command the mobile guard. Over the course of the battle, Khalid would repeatedly make critical and decisive use of that mounted reserve.
Khalid sent out several scouts to keep the Byzantines under observation. In late July, Vahan sent Jabalah with his lightly armoured Christian-Arab forces to reconnoitre-in-force, but they were repulsed by the mobile guard. After the skirmish, no engagement occurred for a month.

Byzantine army
A few days after the Muslims encamped at the Yarmuk plain, the Byzantine army, preceded by the lightly armed Ghassanids of Jabalah, moved forward and established strongly fortified camps just north of the Wadi-ur-Ruqqad.
The right flank of the Byzantine army was at the south end of the plains, near the Yarmuk River and about a mile before the ravines of ''Wadi al Allan'' began. The left flank of the Byzantines was at the north, a short distance before the Hills of Jabiyah began, and was relatively exposed. Vahan deployed the Imperial Army facing east, with a front about long, as he was trying to cover the whole area between the Yarmuk gorge in the south and the Roman road to

Early Muslim sources mention that the army of Gregory had used chains to link together its foot soldiers, who had all taken an oath of death. The chains were in 10-man lengths as a proof of unshakeable courage on the part of the men, who thus displayed their willingness to die where they stood and not to retreat. The chains also acted as an insurance against a breakthrough by enemy cavalry. However, modern historians suggest that the Byzantines adopted the Graeco-Roman testudo military formation in which soldiers would stand shoulder-to-shoulder with shields held high and an arrangement of 10 to 20 men would be completely shielded on all sides from missile fire, each soldier providing cover for an adjoining companion.

The Byzantine cavalry was armed with a long sword, known as the ''spathion''. They would also have had a light wooden

Umar, apparently wanting to defeat the Byzantines first, used the best Muslim troops against them. The continuing stream of Muslim reinforcements worried the Byzantines, who fearing that the Muslims with such reinforcements would grow powerful, decided that they had no choice but to attack. The reinforcements that were sent to the Muslims at Yarmuk arrived in small bands, giving the impression of a continuous stream of reinforcements to demoralize the Byzantines to compel them to attack.

Day 1
The battle began on 15 August. At dawn, both armies lined up for battle less than a mile apart. It is recorded in Muslim chronicles that before the battle started, George, a unit commander in the Byzantine right centre, rode up to the Muslim line and converted to Islam; he would die the same day fighting on the Muslim side. The battle began as the Byzantine army sent its champions to duel with the Muslim

. The mubarizun were specially trained swordsmen and lancers, with the objective to slay as many enemy commanders as possible to damage their morale. At midday, after losing a number of commanders in the duels, Vahan ordered a limited attack with a third of his infantry forces to test the strength and strategy of the Muslim army and, using their overwhelming numerical and weaponry superiority, achieve a breakthrough wherever the Muslim battle line was weak. However the Byzantine assault lacked determination; many Byzantine soldiers were unable to press the attack against the Muslim veterans. The fighting was generally moderate although in some places, it was especially intense. Vahan did not reinforce his forward

, two thirds of which was kept in reserve with one third deployed to engage the Muslims, and at sunset, both armies broke contact and returned to their respective camps.
Day 2
Phase 1: On 16 August, Vahan decided in a council of war to launch his attack just before dawn, to catch the Muslim force unprepared as they conducted their morning prayers.
He planned to engage his two central armies with the Muslim centre in an effort to stall them while the main thrusts would be against the wings of the Muslim army, which would then be driven away from the battlefield or pushed towards the centre. To observe the battlefield, Vahan had a large pavilion built behind his right wing with an Armenian bodyguard force. He ordered the army to prepare for the surprise attack.
However, Khalid had prepared for such a contingency by placing a strong outpost line in front during the night to counter surprises, which gave the Muslims time to prepare for battle. At the centre, the Byzantines did not press hard, intending to pin down the Muslim centre corps in their position and preventing them from aiding the Muslim army in other areas. Thus the centre remained stable, but on the wings the situation was different. Qanatir, commanding the Byzantine left flank, which consisted of mainly

, attacked in force, and the Muslim infantry on the right flank had to retreat. Amr, the Muslim right wing commander ordered his cavalry regiment to counterattack, which neutralized the Byzantine advance and stabilized the battle line on the right for some time, but the Byzantine numerical superiority caused them to retreat towards the Muslim base camp.Phase 2: Khalid, aware of the situation at the wings, ordered the cavalry of the right wing to attack the northern flank of the Byzantine left wing while he with his mobile guard attacked the southern flank of the Byzantine left wing, and the Muslim right wing infantry attacked from the front. The three-pronged attack forced the Byzantine left wing to abandon the Muslim positions they had gained on, and Amr regained his lost ground and started reorganizing his corps for another round.
The situation on the Muslim left wing, which Yazid commanded was considerably more serious. The Muslim right wing enjoyed assistance from the mobile guard but not the left wing, and the numerical advantage the Byzantines enjoyed caused the Muslim positions to be overrun, with soldiers retreating towards base camps. There, the Byzantines had broken through the corps. The

that Gregory's army had adopted moved slowly but also had a good defence. Yazid used his cavalry regiment to counterattack but was repulsed. Despite stiff resistance, the warriors of Yazid on the left flank finally fell back to their camps and for a moment Vahan's plan appeared to be succeeding. The centre of the Muslim army was pinned down and its flanks had been pushed back. However, neither flank had broken though morale was severely damaged.
The retreating Muslim army was met by the ferocious Arab women in the camps. Led by Hind, the Muslim women dismantled their tents, and armed with tent poles, charged at their husbands and fellow men singing an improvised song from the

, which then had been directed against the Muslims.
That boiled the blood of the retreating Muslims so much that they returned to the battlefield.
Phase 3: After managing to stabilize the position on the right flank, Khalid ordered the mobile guard cavalry to provide relief to the battered left flank.
Khalid detached one regiment under Dharar ibn al-Azwar and ordered him to attack the front of the army of Dairjan (left centre) to create a diversion and threaten the withdrawal of the Byzantine right wing from its advanced position. With the rest of the cavalry reserve he attacked Gregory's flank. Here again, under simultaneous attacks from the front and flanks, the Byzantines fell back but more slowly because they had to maintain their formation.
At sunset, the central armies broke contact and withdrew to their original positions and both fronts were restored along the lines occupied in the morning. The death of Dairjan and the failure of Vahan's battle plan left the larger Imperial army relatively demoralized, but Khalid's successful counterattacks emboldened his troops despite their being smaller in number.
Day 3
On 17 August, Vahan pondered over his failures and mistakes of the previous day, where he launched attacks against respective Muslim flanks, but after initial success, his men were pushed back. What bothered him the most was the loss of one of his commanders.
The Byzantine army decided on a less ambitious plan, and Vahan now aimed to break the Muslim army at specific points. He decided to press upon the relatively exposed right flank, where his mounted troops could manoeuvrer more freely as compared to the rugged terrain at the Muslims' left flank. The junction was to be between the Muslim right centre, its right wing held by Qanatir's Slavs, to break them apart so that they would be fought separately.
Phase 1: The battle resumed with Byzantine attacks on the Muslim right flank and right centre.
After holding off the initial attacks by the Byzantines, the Muslim right wing fell back, followed by the right centre. They were again said to have been met by their own women, who abused and shamed them. The corps, however, managed to reorganize some distance from the camp and held their ground preparing for a counterattack.Phase 2: Knowing that the Byzantine army was focusing on the Muslim right, Khalid ibn al-Walid launched an attack with his mobile guard, along with the Muslim right flank cavalry. Khalid ibn al-Walid struck at the right flank of the Byzantines left centre, and the cavalry reserve of the Muslims right centre struck at the Byzantines left centre at its left flank. Meanwhile, he ordered the Muslims' right-wing cavalry to strike at the left flank of the Byzantines left wing. The combat soon developed into a bloodbath. Many fell on both sides. Khalid's timely flanking attacks again saved the day for Muslims and by dusk, the Byzantines had been pushed back to the positions they had at the start of the battle.
Day 4
The fourth day was to prove decisive.
Phase 1: Vahan decided to persist with the previous day's
war plan
A military operation plan (also called a war plan before World War II) is a formal plan for military armed forces, their military organizations and units to conduct operations, as drawn up by commanders within the combat operations process in ach ...
as he had been successful in inflicting damage on the Muslim right.
Qanatir led two armies of Slavs against the Muslim right wing and right centre with some assistance from the Armenians and Christian Arabs led by Jabalah. The Muslim right wing and right centre again fell back.
Khalid entered the fray yet again with the mobile guard. He feared a general attack on a broad front, which he would be unable to repulse, and so ordered Abu Ubaidah and Yazid on the left centre and the left wings, respectively, to attack the Byzantine armies at the respective fronts. The attack would result in stalling the Byzantine front and prevent a general advance of the Imperial army.
Phase 2: Khalid divided his mobile guard into two divisions and attacked the flanks of the Byzantine left centre, and the infantry of the Muslim right centre attacked from the front. Under the three-pronged

, the Byzantines fell back. Meanwhile, the Muslim right wing renewed its offense with its infantry attacking from the front and the cavalry reserve attacking the northern flank of the Byzantine left wing. As the Byzantine left centre retreated under three-pronged attacks of Khalid, the Byzantine left wing, having been exposed at its southern flank, also fell back.
While Khalid and his mobile guard were dealing with the Armenian front throughout the afternoon, the situation on the other end was worsening. Byzantine horse-archers had taken to the field and subjected Abu Ubaidah and Yazid's troops to intense archery preventing them from penetrating their Byzantine lines. Many Muslim soldiers lost their sight to Byzantine arrows on that day, which thereafter became known as the "Day of Lost Eyes". The veteran

is also believed to have lost an eye that day. The Muslim armies fell back except for one regiment, led by Ikrimah bin Abi Jahal, which was on the left of Abu Ubaidah's corps. Ikrimah covered the retreat of the Muslims with his 400 members of the cavalry by attacking the Byzantine front, and the other armies reorganized themselves to counterattack and regain their lost positions. All of Ikrimah's men were either seriously injured or dead that day. Ikrimah, a childhood friend of Khalid, was mortally wounded and died later in the evening.
Day 5
During the four-day offence of Vahan, his troops had failed to achieve any breakthrough and had suffered heavy casualties, especially during the mobile guard's flanking counterattacks. Early on 19 August, the fifth day of the battle, Vahan sent an emissary to the Muslim camp for a truce for the next few days so that fresh negotiations could be held. He supposedly wanted time to reorganize his demoralized troops, but Khalid deemed victory to be in reach and he declined the offer.
Until now, the Muslim army had adopted a largely defensive strategy, but knowing that the Byzantines were apparently no longer eager for battle, Khalid now decided to take the offensive and reorganized his troops accordingly. All cavalry regiments were grouped together into one powerful mounted force with the mobile guard acting as its core. The total strength of the cavalry group was now about 8,000 mounted warriors, an effective mounted corps for an offensive attack the next day. The rest of the day passed uneventfully. Khalid planned to trap Byzantine troops, cutting off their every route of escape. There were three natural barriers, the three gorges in the battlefield with their steep ravines, ''Wadi-ur-Ruqqad'' at west, ''Wadi al Yarmouk'' in south and ''Wadi al Allah'' in east. The northern route was to be blocked by Muslim cavalry.
There were however, some passages across the deep ravines of Wadi-ur-Raqqad in west, strategically the most important one was at Ayn al Dhakar, a bridge. Khalid sent Dharar with 500 cavalry at night to secure that bridge. Dharar moved around the northern flank of Byzantines and captured the bridge, a manoeuvrer that was to prove decisive the next day.
Day 6
On 20 August, Khalid put into action a simple but bold plan of attack. With his massed cavalry force, he intended to drive the Byzantine cavalry entirely off the battlefield so that the infantry, which formed the bulk of the imperial army, would be left without cavalry support and thus would be exposed when attacked from the flanks and rear.
At the same time, he planned to push a determined attack to turn the left flank of the Byzantine army and drive them towards the ravine to the west.Phase 1: Khalid ordered a general attack on the Byzantine front and galloped his cavalry around the left wing of the Byzantines. Part of his cavalry engaged the Byzantine left wing cavalry while the rest of it attacked the rear of the Byzantine left wing infantry. Meanwhile, the Muslim right wing pressed against it from the front. Under the two-pronged attack, the Byzantine left wing fell back and collapsed and fell back to the Byzantine left centre, greatly disordering it. The remaining Muslim cavalry then attacked the Byzantine left wing cavalry at the rear while they were held frontally by the other half of the Muslim cavalry, routing them off the battlefield to the north.
The Muslim right-wing infantry now attacked the Byzantine left centre at its left flank while the Muslim right centre attacked from front.
Phase 2: Vahan, noticing the huge cavalry manoeuvrer of the Muslims, ordered his cavalry to group together, but was not quick enough. Before Vahan could organize his disparate heavy cavalry squadrons, Khalid had wheeled his cavalry back to attack the concentrating Byzantine cavalry squadrons, falling upon them from the front and the flank while they were still moving into formation. The disorganized and disoriented Byzantine

was soon routed and dispersed to the north, leaving the infantry to its fate.Phase 3: With the Byzantine cavalry completely routed, Khalid turned to the Byzantine left centre, which already held the two-pronged attack of the Muslim infantry. The Byzantine left centre was attacked at its rear by Khalid's cavalry and was finally broken.Phase 4: With the retreat of the Byzantine left centre, a general Byzantine retreat started. Khalid took his cavalry north to block the northern route of escape. The Byzantines retreated west towards ''Wadi-ur-Ruqqad'', where there was a bridge at ''Ayn al Dhakar'' for safe crossing across the deep gorges of the ravines of Wadi-ur-Ruqqad. Dharar had already captured the bridge as part of Khalid's plan the night before. A unit of 500 mounted troops had been sent to block the passageway. In fact, that was the route by which Khalid wanted the Byzantines to retreat all along.
The Byzantines were surrounded from all sides now.
Some fell into the deep ravines off the steep slopes, others tried to escape in the waters but were smashed on the rocks below and still others were killed in their flight. Nevertheless, many of the soldiers managed to escape the slaughter. Jonah, the Greek informant of the

Aftermath
Immediately after the operation was over, Khalid and his mobile guard moved north to pursue the retreating Byzantine soldiers and found them near

Evaluation
The Imperial Byzantine commanders allowed their enemy to have the battlefield of his choosing. Even then, they were at no substantial tactical disadvantage. Khalid knew all along that he was up against a force superior in numbers and, until the last day of the battle, conducted an essentially defensive campaign, suited to his relatively limited resources. When he decided to take the offensive and attack on the final day of battle, he did so with a degree of imagination, foresight and courage that none of the Byzantine commanders managed to display. Although he commanded a smaller force and needed all the men he could muster, he had the confidence and foresight to dispatch a cavalry regiment the night before his assault to seal off a critical path of the retreat that he had anticipated for the enemy army.
Because of his leadership at Yarmuk, Khalid ibn al-Walid is considered one of the finest generals in history, and his use of mounted warriors throughout the battle showed just how well he understood the potential strengths and weaknesses of his mounted troops. His

moved quickly from one point to another, always changed the course of events wherever they appeared, and, then just as quickly, galloped away to change the course of events elsewhere on the field.
Vahan and his Byzantine commanders did not manage to deal with the mounted force and use the sizable advantage of their army effectively. Their own Byzantine cavalry never played a significant role in the battle and were held in static reserve for most of the six days. They never pushed their attacks, and even when they obtained what could have been a decisive breakthrough on the fourth day, they were unable to exploit it. There appeared to be a decided lack of resolve among the Imperial commanders, but that may have been caused by difficulties commanding the army because of internal conflict. Moreover, many of the Arab auxiliaries were mere levies, but the Muslim Arab army consisted for a much larger part of veteran troops.
The original strategy of Heraclius, to destroy the Muslim troops in Syria, needed a rapid and quick deployment, but the commanders on the ground never displayed those qualities. Ironically, on the field at Yarmuk, Khalid carried out, on a small tactical scale, what Heraclius had planned on a grand strategic scale. By rapidly deploying and manoeuvring his forces, Khalid was able to concentrate sufficient forces at specific locations on the field temporarily to defeat the larger Byzantine army in detail. Vahan was never able to make his numerical superiority count, perhaps because of the terrain, which prevented large-scale deployment.
However, Vahan never attempted to concentrate a superior force to achieve a critical breakthrough. Although he was on the offensive five out of the six days, his battle line remained remarkably static. That stands in stark contrast to the very successful offensive plan, which Khalid carried out on the final day by reorganising virtually all his cavalry and committing it to a grand manoeuvre, which won the battle.
