And a short time after there broke out a fierce war with the above-mentioned Tartar Lasilbas, from a certain ambition and rivalry which existed between them; when Lasilbas came with a great army against the Suffaveans, and, joining in a fierce and sanguinary contest,[322] bore himself as a valiant man for many hours; nevertheless, the forces of the enemy prevailing, he was repulsed and routed, and saved[323] himself by flight to Samarcant. This victory was the most illustrious that Ismail ever obtained, as he fought against enemies who were great warriors and famous in all the East. For this reason the Turk and the Soldan became greatly apprehensive of the power of Ismail, both considering, that if after all the Tartar happened to be conquered, the road would be opened for Ismail to acquire Asia and Egypt, as in all the East there were no princes more powerful than they, but the Tartar Lasilbas. On this account Selim, the Grand Turk, having heard that Ismail was engaged with the war waged against the city of Samarcant,[324] which was the largest in the possession of the Tartar prince, brought together an immense army of Turks, and advanced in person against Persia, in the year 1514; he marched towards the river of Sivas,[325] which is six hundred miles distant from Constantinople and six hundred and forty from Tauris: so that one may say that it is about half way between the two cities, and having passed the river Lai,[326] he marched forward quickly through the country of Arsenga.[327] Ismail, who was in Tauris without his regular troops, who were engaged in besieging Samarcant, hearing of this, began to levy other forces in haste, and having collected a tolerably good army placed it under two of his most valiant captains, one named Stàcàlu Amarbei and the other Aurbec Samper, and sent them against Selim, in order, by skirmishing, to retard his advance until he had assembled sufficient men to oppose his enemy openly in the field. This army consisted of fifteen thousand horsemen, all good soldiers, and, so to speak, the flower of the Persian people, as the kings of Persia are not accustomed to give pay on the occasion of war, but to a standing force, which is called the “porta” of the king. Thus it is that the Persian gentlemen, to be well brought up, pay great attention to horsemanship, and when necessity calls, go willingly to war, and bring with them, according to their means, a certain number of servants as well armed and mounted as themselves; nevertheless, they do not come out except for the defence of the country; so that, if the Persian soldiery were paid, as is the Turkish, there is no doubt but that it would be far superior to that of the Ottoman princes. This thing has been observed by all those who have had anything to do with both these nations.
