Scarcely were the Christians delivered from these alarms than a new tempest threatened Syria and Palestine.[241] Maudoud, prince or governor of Mossoul, had been killed by two Ismaëlians, as he was coming out of a mosque. As the prince of Mossoul was considered the most firm support of Islamism and the most redoubtable enemy of the Christians, the caliph and the sultan of Bagdad placed him in the rank of the martyrs, and resolved to revenge his death. They accused the Franks and the sultan of Damascus of the murder of a Mussulman prince. A numerous army set out from the banks of the Tigris, and advanced towards Syria, to punish at the same time both the Christian and Mussulman infidels. The warriors of Bagdad, united with those of Mossoul, penetrated as far as the lands of Aleppo, and carried destruction and death wherever they went. In this pressing danger the Saracens of Damascus and Mesopotamia did not hesitate to form an alliance with the Christian princes. The king of Jerusalem, the prince of Antioch, and the count of Tripoli united their troops with those of the Mussulmans. The Christians were full of zeal and ardour, and were eager for battle, but their new allies were not willing to give them the advantage of a victory, as they mistrusted the soldiers of Christ, and used every effort to avoid a decisive engagement, in which they dreaded the triumph of their auxiliaries as much as that of their foes. After having ravaged the territory of Aleppo, and the banks of the Euphrates and the Orontes, the warriors of Bagdad returned to their own country without trying their strength with their formidable adversaries. The Christians in this campaign did not illustrate their arms by any very brilliant exploits, but they kept up the division among the Saracens, and the discord of their enemies was more serviceable to them than a great victory.
