During this diversion of the Mogul arms, Bajazet had two years to collect his forces for a more serious encounter. They consisted of four hundred thousand horse and foot, [39] 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 Timour, and a colony of Tartars, whom he had driven from Kipzak, 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 Suvas. In the mean while, Timour 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 CÊsarea; 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; [40] 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 Timour and the shame of Bajazet. For this signal victory the Mogul emperor was indebted to himself, to the genius of the moment, and the discipline of thirty years. He had improved the tactics, without violating the manners, of his nation, [41] whose force still consisted in the missile weapons, and rapid evolutions, of a numerous cavalry. From a single troop to a great army, the mode of attack was the same: a foremost line first advanced to the charge, and was supported in a just order by the squadrons of the great vanguard. The general's eye watched over the field, and at his command the front and rear of the right and left wings successively moved forwards in their several divisions, and in a direct or oblique line: the enemy was pressed by eighteen or twenty attacks; and each attack afforded a chance of victory. If they all proved fruitless or unsuccessful, the occasion was worthy of the emperor himself, who gave the signal of advancing to the standard and main body, which he led in person. [42] But in the battle of Angora, the main body itself was supported, on the flanks and in the rear, by the bravest squadrons of the reserve, commanded by the sons and grandsons of Timour.
