During this diversion of the Mongol arms, Bajazet had two years to collect his forces for a more serious encounter. They consisted of four hundred thousand horse and foot whose merit and fidelity were of an unequal complexion. We may discriminate the janizaries, who have been gradually raised to an establishment of forty thousand men; a national cavalry (the _spahis_ of modern times); twenty thousand cuirassiers of Europe, clad in black and impenetrable armor; the troops of Anatolia, whose princes had taken refuge in the camp of Timur: and a colony of Tartars, whom he had driven from Kiptchak, and to whom Bajazet had assigned a settlement in the plains of Adrianople. The fearless confidence of the Sultan urged him to meet his antagonist; and, as if he had chosen that spot for revenge, he displayed his banner near the ruins of the unfortunate Sebaste. In the mean while Timur moved from the Araxes through the countries of Armenia and Anatolia. His boldness was secured by the wisest precautions; his speed was guided by order and discipline; and the woods, the mountains, and the rivers were diligently explored by the flying squadrons, who marked his road and preceded his standard. Firm in his plan of fighting in the heart of the Ottoman kingdom, he avoided their camp, dexterously inclined to the left, occupied Caesarea, traversed the salt desert and the river Halys, and invested Angora; while the Sultan, immovable and ignorant in his post, compared the Tartar swiftness to the crawling of a snail. He returned on the wings of indignation to the relief of Angora; and as both generals were alike impatient for action, the plains round that city were the scene of a memorable battle, which has immortalized the glory of Timur and the shame of Bajazet.
