The Arab Historian, Al Waqidi, tells us in his book "The conquering of Al Sham (greater Syria)" that: "In a battle that took place in Beit Lahia near Ajnadin, Khalid watched a knight, in black attire, with a big green shawl wrapped around his waist and covering his bust. That knight broke through the Roman ranks as an arrow. Khalid and the others followed him and joined battle, while the leader was wondering about the identity of the unknown knight."
Rafe' Bin Omeirah Al Taei was one of the fighters. He described how that knight scattered the enemy ranks, disappeared in their midst, reappeared after a while with blood dripping from his spear. He swerved again and repeated the deed fearlessly, several times. All the Muslim army was worried about him and prayed for his safety. Rafe' and others thought that he was Khalid, who had won great fame for his bravery and genius military plans. But suddenly Khalid appeared with a number of knights. Rafe' asked the leader: “Who is that knight? By God, he has no regard for his safety!"
Khalid answered that he didn't know the man, though he greatly admired his courage. He called on the arm to attack as one man and to make sure that they protect their hero(ine). They were fascinated as they watched the knight appear with a number of Roman knights chasing him. Then he would turn around and kill the nearest before resuming his attacks.
The Romans eventually lost the battle and fled, leaving many dead and wounded in the battlefield. Khalid looked for the knight until he found him. By then he was covered in blood. He praised his bravery and asked him to remove his veil. But the knight did not answer, and tried to break away. The soldiers wouldn't let him do that. And everyone asked him to reveal his identity.
When the knight found that there was no way to avoid that, he replied in a feminine voice: "My prince, I did not answer because I am shy. You are a great leader, and I am only a woman whose heart is burning."
"Who are you?" Khalid insisted.
"I am Khawla Bint Al Azwar. I was with the women accompanying the army, and when I learnt that the enemy captured my brother, I did what I did."
Khalid ordered his army to chase the fleeing Roman army, with Khawla leading the attack, looking in all directions for her brother, but in vain. By noontime, the victory was decisive. Most of the Roman soldiers were killed.
Knowing that the prisoners had to be somewhere, Khalid sent Khawla with a number of knights to find them. After a hot chase, they managed to catch up with a Roman detachment that was taking the prisoners to their headquarters. Another fight took place, the Roman guards were all killed and the prisoners saved.
In another battle in Ajnadin, Khawla's spear broke, and her mare was killed, and she found herself a prisoner. But she was astonished to find that the Romans attacked the women camp and captured several of them. Their leader gave the prisoners to his commanders, and order Khawla to be moved into his tent. She was furious, and decided that to die is more honorable than living in disgrace. She stood among the other women, and called them to fight for their freedom and honor or die. The others were enthusiastic to her plan. They took the tents' poles and pegs and attacked the Roman guards, keeping a formation of a tight circle, as she told them.
Khawla led the attack, killed the first guard with her pole, with the other women following her. According to Al Waqidi, they managed to kill 30 Roman knights, while Khawla was encouraging them with her verses, which in fact caused their blood to boil.
The Roman leader was infuriated by what happened, and led a detachment of his knights against the women, though he tried first to tempt them with many promises. He told Khawla that he planned to marry her and make her the first lady of Damascus. But she answered him calmly and with great contempt: "I wouldn't even accept you to be a shepherd of my camels! How do you expect me to degrade myself and live with you? I swear that I'll be the one to cut off your head for your insolence."
In the ensuing battle, the ladies proved their mettle, kept their grounds for some time, encouraging each other and driving off the attackers with their long poles. Suddenly, Khalid and the army reached the battlefield. In the ensuing fight, over 3.000 Romans were killed. The women who took part in the fighting were proud to say that Khawla killed five knights, including the leader that insulted her.
In another battle, the Muslims were overwhelmed by a much bigger Roman army. Many soldiers fled away, but not for long. Khawla and the other women met the fleeing soldiers, questioning their claims of bravery and forced them to return to the battle. The men were stunned when they saw Khawla drawing her sword and leading a counter-attack. They turned their horses and joined the battle, which was eventually won.
One of the knights present that day said: "Our women were much harsher with us than the Romans. We felt that going back to fight and die was much easier than facing the fury of our women later on".
Following his succession as the fourth caliph, Ali (may Allah be pleased with him) married Khawla. She became a legend during her life and remains a legend to this day. Khawla set an example to men and women alike that one should fight for what he or she believes in, and never accept defeat.
