In this year [1240] Batu Khan approached and surrounded the city of Kiev with a great multitude of soldiers. The Tartar forced besieged it and it was impossible for any one either to leave the city or to enter it. Squeaking of wagons, bellowing of camels, sounds of trumpets and organs, neighing of horses, and cry and sobs of an innumerable multitude of people made it impossible to hear one another in the city. The entire country was overflowing with Tartars. The Kievans then captured a Tartar by the name of Tavrul, and he named al the great princes who were with Batu, and spoke of his innumerable strength. And he had with him the following of his brothers and of his strong military leaders: Urdiuy, Baydar, Biriuy, Kaydar, Bechar, Mengay, Kailug, [and] Kuiuk; but he [Kuiuk] returned [to Mongolia] when he learned of the death of the [Great] Khan.
