The Turks, seeing the road closed to them, and knowing that they must either open it sword in hand or, to their great disgrace, be routed and cut to pieces, as happens when inspired by desperation, made a virtue of necessity, and also arrayed themselves with great ardour for the battle.[237] The Turk then having left Ustrefo with a considerable garrison in charge of his camp, set out to scale the mountain on another side, which was not occupied by the Persian troops. Ussun Cassano, seeing them leave the camp, sent Unghermaumet, his son, with a squadron of ten thousand cavalry to oppose Ustrefo, and to cut off all hope of safety from the Turk. And having made three other large divisions, he gave the right wing to Pirameto,[238] the Caramanian Prince, and the left to Ezeinel, his son, commanding in person the centre with all the infantry, which was in magnificent condition. And the battle having begun at the fourteenth hour, the action lasted eight hours continuously, the Persians resisting that great army with such valour, that their personal prowess was wonderful to see; and if Mustafà, the son of the Turk, had not attacked with a fresh squadron the right flank of the Caramanian, the victory would have remained uncertain still longer; as, when the Caramanian gave way before the fresh assault of Mustafà, everything was thrown into confusion in that quarter.[239] Thus it was, that in his retreat he disordered the flank of the line of battle of Ussun Cassano, who, on account of the confusion of his troops and the attack of the enemy in front, saw himself so pressed that he was afraid of being surrounded. Therefore, seized with no small fear on account of the uncertainty of affairs, he jumped off his horse and mounted a swift mare, which he always kept ready for such emergencies; and seeing himself pressed more and more every hour and driven in on the right wing, he turned round and fled. His son Ezeinel seeing this, threw himself with great courage into the midst of the infantry and endeavoured to make head, so that the whole army might not be routed by one charge of the enemy; but, however much this gallant young man might sustain the fury of the Turks, being at length killed by them, the Persians were routed and put to flight. Unghermaumet, who had gone to attack the camp of the Turks guarded by Ustrefo, met with great resistance, but nevertheless hoped to have taken it in time; but, seeing the rout of his father, withdrew little by little, and was in great danger of being made prisoner; since, before his retreat, the Turks had occupied all the plain. However, by making great exertions, he escaped and rejoined his father. The latter not considering himself safe in his camp, which was ten miles distant from the field of battle, crossed the Euphrates, and retired with the rest of his men to the interior of his country. This fight took place in the year 1473, in which ten thousand Persians and fourteen thousand Turks fell.
