It was incumbent on the Saracens to exert the full powers of their valor and enthusiasm against the forces of the emperor, who was taught, by repeated losses, that the rovers of the desert had undertaken, and would speedily achieve, a regular and permanent conquest. From the provinces of Europe and Asia, fourscore thousand soldiers were transported by sea and land to Antioch and CÊsarea: the light troops of the army consisted of sixty thousand Christian Arabs of the tribe of Gassan. Under the banner of Jabalah, the last of their princes, they marched in the van; and it was a maxim of the Greeks, that for the purpose of cutting diamond, a diamond was the most effectual. Heraclius withheld his person from the dangers of the field; but his presumption, or perhaps his despondency, suggested a peremptory order, that the fate of the province and the war should be decided by a single battle. The Syrians were attached to the standard of Rome and of the cross: but the noble, the citizen, the peasant, were exasperated by the injustice and cruelty of a licentious host, who oppressed them as subjects, and despised them as strangers and aliens. A report of these mighty preparations was conveyed to the Saracens in their camp of Emesa, and the chiefs, though resolved to fight, assembled a council: the faith of Abu Obeidah would have expected on the same spot the glory of martyrdom; the wisdom of Caled advised an honorable retreat to the skirts of Palestine and Arabia, where they might await the succors of their friends, and the attack of the unbelievers. A speedy messenger soon returned from the throne of Medina, with the blessings of Omar and Ali, the prayers of the widows of the prophet, and a reÎnforcement of eight thousand Moslems. In their way they overturned a detachment of Greeks, and when they joined at Yermuk the camp of their brethren, they found the pleasing intelligence, that Caled had already defeated and scattered the Christian Arabs of the tribe of Gassan. In the neighborhood of Bosra, the springs of Mount Hermon descend in a torrent to the plain of Decapolis, or ten cities; and the Hieromax, a name which has been corrupted to Yermuk, is lost, after a short course, in the Lake of Tiberias. The banks of this obscure stream were illustrated by a long and bloody encounter. On this momentous occasion, the public voice, and the modesty of Abu Obeidah, restored the command to the most deserving of the Moslems. Caled assumed his station in the front, his colleague was posted in the rear, that the disorder of the fugitive might be checked by his venerable aspect, and the sight of the yellow banner which Mahomet had displayed before the walls of Chaibar. The last line was occupied by the sister of Derar, with the Arabian women who had enlisted in this holy war, who were accustomed to wield the bow and the lance, and who in a moment of captivity had defended, against the uncircumcised ravishers, their chastity and religion.
