But meantime partial defeat had discouraged the leaders of the armies in Syria, and the caliph summoned Khaled to the command of the northern armies. Leaving the army in Persia under the command of a tried and trusty general, Khaled with an escort of fifteen hundred men spurred across the Syrian borders to join the Moslem host about to besiege the Christian city of Bosra.

It was on the Syrian frontier, a walled city of great strength and wealth, that could at anytime put twelve thousand men into the field.

After two days of furious battle the city was taken by treachery, many were massacred, and the survivors were compelled to pass under the yoke.

Khaled now aspired to the capture of Damascus. This renowned and beautiful city, one of the largest and most magnificent in the East and possibly the oldest in the world, stood in a plain of wondrous fertility, covered with groves and gardens. Through this plain flowed a river called by the ancients “The Stream of Gold,” feeding the canals and water courses of its gardens and the fountains of the city.

This most beautiful city lay at the mercy of the coming foe. As the Moslems accustomed to the barrenness of the desert came in sight of the rich plain of Damascus and wound along the banks of the shining river, it seemed as if they were already realizing the paradise promised by the Prophet to true believers: but when the walls and towers and fanes of the city rose upon their vision they could not restrain their shouts of rapture. For the many deeds of valor and personal prowess in single combat, and the fierce and repeated charges of either army, the reader may be referred to the brilliant pages of Irving’s Mahomet or Ockley’s Saracens.

The inhabitants tried to bribe Khaled to raise the siege. The stern reply was: Embrace Islam, pay tribute; or fight unto the death. While the Arabs lay close encamped about the city as if watching its expiring throes, unusual shouts were one day heard within its walls. The cause of it proved to be that an army of one hundred thousand men sent by Heraclius from Antioch were drawing near to their relief.

With fierceness yet the coolness of a practiced warrior Khaled marched to the support of a small body of horsemen who had been sent to harass the enemy. He met and defeated division after division of this Roman army, defeating it in detail by an army less than a third of their number. Thousands of fugitives were slain in the pursuit that followed. An immense booty in treasure, arms, baggage, and horses fell into his hands; and Khaled flushed with conquest, fatigued and burdened with the spoils, led back his army to resume the siege of Damascus.

Word was soon received however that another army of seventy thousand men had been gathered by Heraclius to raise the siege of Damascus. Sending swift couriers to all the Moslem generals within his call to meet him at the camp of the Greeks, he began a hasty march to Aiznadin. When the Moslems beheld the multitude and formidable array of the imperial host they at first quailed at the sight: but Khaled harangued them with fervid speech: “You behold,” he said, “the last stake of the infidels. This army met and vanquished they can never muster another force, and all Syria is ours.” Khaled armed the fierce women who were among them—some of them of the highest rank with orders to slay any Moslem whom they saw turning his back to the foe. Reinforced by fresh thousands, when, after some preliminary skirmishes, on the second day the trumpets sounded a general charge, the imperial armies were struck with confusion and what followed was rather a massacre than a battle. They broke and fled in all directions to Cæsarea, to Damascus and to Antioch. The booty of the camp was of immense value, which Khaled declared should not be divided until after the capture of Damascus.

Great indeed was the consternation in the city when they learned from the fugitives that escaped, of the slaughter of this second army and that all hope of succor was gone. But they set themselves bravely to work to meet the coming storm. New fortifications were erected. The walls were lined with engines for hurling stones and darts upon the besiegers.

Soon the Moslems appeared greatly reinforced. The city was invested. The troops were carefully stationed and orders given as to the support to be given. The battles that followed were fierce as the passions of desperate men could make them. One day a simultaneous sortie was made from every gate of the city at the first peep of day. The besiegers were taken by surprise and were struck down before they could arm themselves or mount. Khaled is said to have wept as he beheld the carnage and the slaughter of his finest troops. “O thou, who never sleepest, aid thy faithful servants; let them not fall beneath the weapons of the infidels.” Finally the tide of battle turned and the Christians were repulsed and driven within the walls leaving several thousand dead on the field. It was no disgrace for even such Christians to be beaten by such Moslems.
