The Third Fitna Ends: The Battle of Madīnah
March 11, 744 - Near Madīnah, Modern Al-Mulaylih
After capturing Tabūk with some tranquility, the army of Sulayman and Uqba march toward the holy city of Madīnah, hearing of the new Caliph in power, both separate their armies, Uqba with 37.000 soldiers and Sulayman with 21.000, most of them the forces previously used by both, Uqba having one with great composition of berbers and Sulayman with its same original strength, which has its cons. Sulayman has been battling with the same forces without much rest since the Battle of Damascus, while Uqba has periodically rotated his troops with new volunteers in Egypt.
Yazid, however, gathers 18.000 soldiers, and after hours of prayer in Madīnah, departs with his army to meet the enemy. The battle begins as soon as the troops catch sight of each other, with archers exchanging fire, Yazid archers achieving better results by using the small mound behind the sand valley. With the battle formations ready, the battle begins.
A group of bedouins suddenly arrives in Yazid, and reports the same of a large army arriving on their right. Thinking of it as a trap, he accepts the bedouin's information, but does nothing about it, and sends his army into combat. Knowing Sulayman's track record of aggressivity, Yazid orders his cavalry to engage the enemy along with the infantry, while the archers hold the flanks and rear. Sulayman orders a similar formation, but with the cavalry also at the rear, a move that Yazid considers strangely conservative for the opponent he is facing.
Sulayman's infantry resist the attack well using square formations, but Yazid soon orders the cavalry units to engage evenly with the infantry, thus causing breaches that break the square formations, and soon the infantry almost collapses from Sulayman. He soon orders his cavalry reserves and archers to join and reinforce the infantry, which delays but not prevent what seems an imminent victory for Yazid. But Sulayman soon changes his worry face to a wide smile.
Uqba's army arrives on Yazid's right flank, crushing the troops on his arrival, suddenly, morale becomes nonexistent in the Caliph's troops, his officers no longer understand what is happening, as the lines collapsed, the right victory comes to be the worst possible defeat.
By the end of the day, Yazid would have been captured by the forces of Uqba, and the next day the troops would be entering Madīnah and gloriously heading towards Makkah.
March 21, 744 - Makkah
Sulayman's troops triumphantly enter Makkah, capturing the new umayyad court by surprise and taking everyone out of town to face together with Yazid death. Following the capture of Makkah, Uqba and Sulayman would pass along with the Abbasid troops making a process of pacifying the peninsula. And after that, the Third Fitna is finally over.
