List three reasons why the battle of yarmuk was the "fiercest and bloodiest kind" pls pls pl :)

In this battle 24,000 Muslims took part. The Greeks and their followers in this battle tied themselves to each other by chains, so that no one might set his hope on flight.

Muslim women took part and fought violently. Among them was Hind, daughter of 'Utbah and mother of Muawiya ibn-abi-Sufyan, who repeatedly exclaimed, "Cut the arms of these 'uncircumcised' , with your swords!"

abdallah ibn-al-Aiham sided with the Ansar saying, "Ye are our brethren and the sons of our fathers," and professed Islam. After the arrival of 'Umar ibn-al-Khattab in Svria, year 17, Jabalah had a dispute with one of the Muzainah and knocked out his eve. 'Umar ordered that he be punished, upon which Jabalah said, "Is his eye like mine? Never, by Allah, shall I abide in a town where I am under authority."
