|strength1=140,000
|strength2=85,000 mostly cavalry, and also 32 war elephants. Bayezid's army numbered 85,000. The Ottoman force included contingents under his sons, Ghazis, Janissaries, Anatolian Muslim vassals, and various European (Balkan Christian) vassals. Among Serbian vassals participating were Stefan Lazarević, Vuk Lazarević, Đurađ Branković and his brother Grgur Branković, and among Albanian were Koja Zakarija, Demetrius Jonima, Gjon Kastrioti, and probably Tanush Dukagjini. Christian vassals that did not participate include Zetan Konstantin Balšić. A quarter of the Ottoman troops were recently conquered Tatars.

Bayezid reluctantly withdrew his forces from the blockade of Constantinople and marched them through the midsummer heat. When they arrived, they were tired and thirsty, but were allowed no time to rest or recuperate. Bayezid was advised by his generals to take up defensive positions and, when Timur's forces pushed back the Ottomans, to withdraw into the mountains and force Timur to break ranks and attempt to hunt the Ottomans in their own terrain during the midsummer heat. Bayezid instead chose to take an offensive stance and marched eastward. Advancing Ottoman scouts found no traces of the Timurids, who secretly marched southwest, rested, and were situated to the rear of the Ottomans. The Timurids encamped in the same locations that the Ottomans had previously occupied, making use of abandoned tents and water sources. In the Timurid army, Timur commanded the centre, his sons Miran and Rukh the right and left, respectively, and his grandsons the vanguard. In the Ottoman army, Bayezid commanded the centre with Janissaries, his son Suleyman the left flank with the best troops, Stefan Lazarević the right with the Balkan troops, and his son Mehmed the rear guard.

The battle began with a large scale attack from the Ottomans, countered by swarms of arrows from the Timurid horse archers. Several thousand were killed and many surrendered to Timur. Stefan Lazarević and his knights successfully fought off the Timurid assaults and cut through the Mongol ranks three times. Each time Stefan advised Bayezid to break out with him, Bayezid declined to do so. But the Serbians managed to save one of Bayezid's sons and the treasury from the Mongols and made their way to Constantinople. The Serbian troops wore heavy black plate armour which was very effective against the Timurid arrows. Timur admired the Serbian troops who according to him "fight like lions". During the battle the main water supply of both armies, Çubuk creek, was diverted to an off stream reservoir near the town of Çubuk by Timur, which left the Ottoman army with no water. The final battle took place at Catal hill, dominating the Çubuk valley. The Ottoman army, both thirsty and tired, was defeated, though Bayezid managed to escape to the nearby mountains with a few hundred horsemen. However, Timur had the mountains surrounded and, heavily outnumbering Bayezid, soon captured him. He died in captivity three months later. Already heavily outnumbered, the Ottoman army was further weakened by the desertion of the Black Tatars and the Sipahis from the Anatolian beyliks, who left Bayezid's side and joined Timur's forces.

After the battle, Timur moved through western Anatolia to the Aegean coast, where he besieged and took the city of Smyrna, a stronghold of the Christian Knights Hospitalers. The battle was catastrophic for the Ottoman state, fracturing what remained and bringing almost total collapse of the empire. This resulted in a civil war among Bayezid's sons. The Ottoman civil war continued for another 11 years (1413) following the Battle of Ankara. The battle is also significant in Ottoman history as being the only time a Sultan was captured in person.
