For this reason Alamur, being more alarmed than he ever was in the time of his father, summoned all the great Persian lords to court, and, having collected fighting men, marched with his army against Ismail. The latter, finding his forces too weak to take the field, and, if an opportunity offered, to give battle to the king, sought the aid of some Georgian Christian chiefs whose land bordered on that country, whose names were Alexander Beg, Gurgurabet, and Mirabet. These, as they had an ancient enmity against Alamur, and wished to overthrow his power, availing themselves of the opportunity given by Ismail, decided to assist him against Alamur, and therefore each of them sent three thousand horse, so that they were altogether nine thousand excellent soldiers; these are the people who were anciently called Iberians, and as they then were, and still are, Christians, have continually waged war with the Turks on the frontiers of Trebizond. They were joyfully welcomed, and received many presents from Ismail, who, with these Georgian auxiliaries, found himself with an excellent army of sixteen thousand men in the field. Thence he advanced with the intention of giving battle to Alamur, if he had an opportunity, and thus both approached each other between Tauris and Sumachi, near a great river,[294] where Alamur, who had an army of thirty thousand men, infantry and cavalry, having placed himself on his guard, occupied the only two bridges by which Ismail could cross into the territory in which he was posted. He did it with the intention that the enemy, finding the passage barred to them, might not, with the daring which they say is often favoured by fortune, stake all on one throw, and force him to fight against his will.
