OF THE ROMAN EMPIRE 387 caliph encountered and defeated the superior numbers of the rebels under the walls of Bassora. Their leaders, Telha and Zobeir, were slain in the first battle that stained with civil blood the arms of the Moslems. After passing through the ranks to animate the troops, Ayeslia had chosen her post amidst the dangers of the field. In the heat of the action, seventy men who held the bridle of her camel were successively killed or wounded ; and the cage or litter in which she sat was stuck with javelins and darts like the quills of a porcupine.

In this sanguinary contest, the lawful caliph dis- played a superior character of valour and humanity. His troops were strictly enjoined to await the first onset of the enemy, to spare their flying brethren, and to respect the bodies of the dead and tlie chastity of the female captives. He generously proposed to save the blood of the Moslems by a single combat ; but his trembling rival declined the challenge as a sentence of inevitable death. The i-anks of the Syrians were broken by the *^' charge of a hero who was mounted on a piebald horse, and wielded with irresistible force his ponderous and two-edged sword.
