Bayezid for some time after his capture was treated with unwonted generosity by Timur, who was impressed by his dignified bearing, in spite of his overwhelming defeat and humiliation. But after an attempt to escape he was more rigidly guarded, and was put into fetters at night. The treatment of him became more cruel and contemptuous. He was carried by day in the train of Timur, when on the march, in a litter, which was in effect a cage[12] with open bars, exposed to the derision and contempt of the Tartars. His wife, Despina, the Serbian princess, was compelled to serve Timur with drink at his meals in a state of nudity, and with other women of Bayezid’s harem was taken into that of the conqueror. Timur is also said to have made a footstool of his conquered foe. Bayezid died of a broken heart after eight months of humiliation, at the age of forty-eight. During that time Timur overran the greater part of Asia Minor, capturing Nicæa and Brusa and many other strongholds from the Ottomans, and Smyrna from the Knights of St. John of Jerusalem. The walls of Smyrna were undermined in the same way as those of Sivas. In two weeks Timur effected a capture which Bayezid had failed to do in three times that length of time. The Knights, when they found that the city was no longer tenable, fought their way down to their galleys against the crowd of despairing inhabitants. Most of them escaped to Rhodes and effected there another settlement. Those who failed to escape were put to death by Timur, who built a pyramid of their heads. Everywhere there was ruthless cruelty. When approaching the city of Ephesus, children came out to meet him singing songs to appease his wrath. “What is this noise?” he asked. When told, he ordered his horsemen to ride over the children. They were trampled to death. Timur reinstated in their former territories, as tributaries to his own Empire, most of the petty princes who had been dispossessed by the Turks, including the Emir of Karamania. He eventually returned to Samarkand, where he made preparations for the invasion of China, but before this could be realized he died, at the age of seventy-one, two years after the death of Bayezid. As a result of his raid into Asia Minor the Ottoman Empire there, for the time being, completely collapsed. But the Tartars disappeared without leaving any trace behind them.
