Carey states on p. 128 that Batu had 40,000 in the main body and ordered Subotai to take 30,000 troops in an encircling maneuver. Batu commanded the central prong of the Mongols' three-pronged assault on eastern Europe. This number seems correct when compared with the numbers reported at the Battles of Legnica to the North and Hermannstadt（英语：Battle of Hermannstadt） (錫比烏) to the South. All three victories occurred in the same week.
