Bayezid, thus challenged, advanced, in 1401, with an army of one hundred and twenty thousand men to avenge the disaster at Sivas. Timur, however, after the capture of that city, refrained from advancing farther into Asia Minor. He passed into Syria and captured Damascus, and thence into Mesopotamia for the capture of Bagdad. It was not till the next year, 1402, that he determined to return to Asia Minor and to humble Bayezid. He retraced his steps to Sivas, and thence, after a further exchange of insolent messages with the Ottoman Sultan, he went in search of him towards Angora, taking the route of Cæsarea and Kir Sheir. Bayezid had also collected a great army in the east of Asia Minor, and had finally concentrated it in the neighbourhood of Angora. He showed none of his previous skill as a general, though all of his insolence and bravado. His army was discontented by his avarice, and by his neglect to pay them out of the well-filled treasury. He refused to follow the advice of his best generals, who warned him against meeting Timur’s vast hosts on a field where they could deploy their whole strength. The two armies met at last on the plain of Angora, the site of many previous famous battles. It is almost inconceivable that Bayezid, in arrogant contempt of his foe, employed his army, in the face of the enemy, in a great hunt for game, which led them into a district devoid of water, where his soldiers suffered terribly, and five thousand are said to have died of thirst. On return to their camp they found that Timur had diverted the stream which supplied it with water. Bayezid was forced to fight at a disadvantage. The Tartars, who formed a fourth part of the Ottoman army, were not to be relied on in this battle. Their sympathies were with their fellow-Tartars under Timur. Bayezid had committed the fatal error of placing them in the front line, after his usual tactics of meeting the first encounter of the enemy with inferior troops. But in this case the Tartars deserted on the field of battle. The Serbian contingent, under Prince Stephen, and other Christian vassal troops fought with the utmost gallantry and loyalty. But it was in vain. The whole Ottoman army was outnumbered, overwhelmed, and routed with great slaughter. Bayezid with his bodyguard made a last stand. “The Thunderbolt,” says the Turkish historian, “continued to wield a heavy battle-axe. As a starving wolf scattering a flock of sheep he scattered the enemy. Each blow of his redoubtable axe struck in such a way that there was no need of a second blow.” But in the end he was overpowered and taken prisoner.
