[EX Q]: 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.

[EX Q]: Question: What aircraft beside the Sopwith Camel did No. 66 Squadron RFC operate? Passage:This extended training period meant that he had accumulated 138 flying hours in his pilot's logbook before he finally joined No. 66 Squadron RFC in Italy on 10 March 1918. He was assigned to "C" Flight, flying a Sopwith Camel single seat fighter, and became the preferred wingman of fellow Canadian ace Billy Barker. Birks' first aerial victory came on 18 March, when he destroyed a Rumpler reconnaissance aircraft over Pravisdomini, killing an Austro-Hungarian pilot named Shneeberger. Six days later, he set another reconnaissance aircraft on fire, killing the crew of Poelzi and Suski. His third victory would not come until 2 May, when he wounded Leutnant K. Kosiuski and drove him into a crash landing that destroyed his Albatros D.V. Two days later, Birks shot down and killed ace Oberleutnant Karl Patzelt, as well as F. Frisch. In addition to killing both Austro-Hungarian pilots, he destroyed both their Albatros D.Vs; they were credited as "captured" because they fell within Italian lines. The new ace shot down another D.V in flames a week later, on 11 May. He destroyed two Berg fighters in five minutes on a morning patrol on 19 May. The following day, he destroyed another. On 24 May, while flying with Barker, Birks was credited with shooting down Hungarian ace József Kiss of Flik 55J; Birks thus became a double ace. On 9 June Birks set another Albatros D.V on fire in mid-air. On the 21st, he capped his list of triumphs by destroying another D.V over Motta. Most unusually for a British pilot, he had no "soft" victories, such as "driven down out of control".
