Shortly after the commencement of the new year, (586, Hejir which began Feb. 9th, A. D. 1190,) Saladin collected his troops together, to raise the siege of Acre. He moved from Al Kherûba to Tel Al Ajûl, where he pitched his camp. He was there joined by his son Al Malek, Al Daher Gayâtho’ddîn Gâzi, the governor of Aleppo, with a select body of cavalry, and by Mohaffero’ddîn I’Bn Zinoddin, with his light horse. The Templars and the crusaders, during the winter, had not been idle; they had dug trenches around their camp, thrown up ramparts, and fortified their position in such a way that it would have been difficult, says the Arabian writer, for even a bird to get in. They had, moreover, filled up the ditch around the town, and constructed three enormous towers, the largest of which was much higher than the walls, was sixty cubits in length, and could contain from five to six hundred warriors, with a proper quantity of arms and military engines. These towers were covered with the raw hides of oxen soaked in vinegar and mud, to render them incombustible; they were strengthened from top to bottom with bands of iron, and were each divided into five platforms or galleries filled with soldiers and military engines. They were rolled on wheels to the walls, and the Templars and the crusaders were about to descend from the platforms and galleries upon the battlements of the city, when the towers, and all the warriors upon them, were consumed by some inextinguishable inflammable composition, discharged out of brass pots by a brazier from Damascus. “We were watching,” says Bohadin, who was standing in the Moslem camp by Saladin’s side, “with intense anxiety the movements of the soldiers upon the towers, and thought that the city must inevitably be taken, when suddenly we saw one of them surrounded with a blaze of light, which shot up into the skies; the heavens were rent with one joyous burst of acclamation from the sons of Islam, and in another instant another tower was surrounded with raging flames and clouds of black smoke, and then the third; they were ignited one after the other in the most astonishing and surprising manner, with scarce an interval of a minute between them. The sultan immediately mounted his horse, and ordered the trumpets to sound to arms, exclaiming with a loud voice, in the words of the prophet, ‘When the gate of good fortune is thrown open, delay not to enter in.’” At the commencement of the summer Saladin detached a considerable portion of his forces to the north, to oppose the progress of the German crusaders and Templars, who were advancing from Constantinople, under the command of the emperor Frederic Barbarossa. These advancing Templars were the especial favourites of Barbarossa, and after his melancholy death, from the effects of a cold bath in the river Cydnus, they formed part of the body-guard of his son the duke of Suabia.
