Input: Consider Input: Question: How many soldiers fought under the combined Cossack-Tatar side under chief Asand Demko? Passage:He began his studies in Poland and continued his education at the University of Leuven. His considerable wealth enabled him to establish his own private army, which suppressed Cossack riots and Tatar raids in Ukraine. In 1635 he became the first voivode of the Czernihów Voivodship. In 1646 he was appointed Field Crown Hetman. During the Khmelnytsky Uprising, he was captured by the Tatars after the Battle of Korsun in 1648. He was a prisoner-of-war until 1650 when he was ransomed. On 12 May 1651 he commanded victorious Polish army in the Battle of Kopyczyńce between Poles and combined Cossack-Tatar forces under chief Asand Demko. In 1651, during the subsequent hostilities between the Commonwealth and Cossack-Tatar alliance, he was the nominal commander of the Polish army right wing at the great victorious Battle of Beresteczko (de facto commanded Jeremi Wiśniowiecki). Upon death of Grand Crown Hetman Mikołaj Potocki, who was his political and personal adversary, hetman Kalinowski commanded the choicest elements of the Commonwealth army and he had at the camp at Batoh about 10–12,000 soldiers and 10–15,000 servants and camp followers. This army was surprised by the combined Cossack-Tatar army, consequently defeated and then capture of Polish soldiers and servants resulted in a wholesale slaughter of the best elements of Commonwealth army and their retinues, the event known as Battle of Batoh. Hetman was killed on 2 June 1652, during the last day of the battle, when trying to escape from the Cossack-Tatars-filled burning Polish camp, in woods some 3 kilometers from the Polish camp. Hetman's severed head was carried around the Cossack-Tatar camps, allegedly by the Nuredin-Sultan himself.

Input: Consider Input: Question: How old was Ali Bey al-Kabir the year that he had a violent confrontation with Uthman Pasha al-Kurji? Passage:Also in 1764, while Uthman was leading the annual Hajj pilgrimage, he had a violent confrontation with Ali Bey al-Kabir, an influential mamluk from Egypt. When Ali Bey was exiled by the governor of Egypt to Gaza (part of Damascus Eyalet) in 1766, Uthman attempted to drive him out. Uthman managed to have his son, Darwish Pasha, appointed as the governor of Sidon in November 1770 and sometime prior to that, had his other son, Muhammad Pasha, appointed as governor of Tripoli. In 1771, Ali Bey, by now the rebellious governor of Egypt, had dispatched an army under commanders Abu al-Dahab and Ismail Bey to subdue Damascus. Together with Zahir, the combined armies of Egypt and Palestine defeated Uthman's army outside of Damascus and Uthman fled north to the city of Homs. The city fell shortly thereafter, although they did not capture the Citadel of Damascus, which was subsequently besieged. However, Abu al-Dahab suddenly withdrew from the area, citing his fears of violating Islamic principles since seizing an Ottoman province was in effect a direct challenge to the authority of the Ottoman sultan, who held the highest religious honor as the caliph of Islam.
