Batalla de Yique

(...) For a example, in a battle with Han and Wei in 293 BC, Bo Qi's troops were outnumbered by 240,000 allied troops. But as Han's and Wei's armies fought separately without unified command, Bo Qi could defeat them one by one. Even in the direct confrontation with Zhao in 262-257 BC, Qin mobilized only its standing army plus male populations aged fifteen and older from the nearby Henei commandery. Classical texts report that Zhao lost more than 400,000 troops in this war. While this figure is likely to be inflated, Zhao apparently engaged in masive -if not total- mobilization to fend off Qin's agression. For Qin, mobilization on a comparable scale occurred only in the final wars of unification. In the war against Chu in 226-223 BC, Qin is recorded to have mobilized 600,000 troops after the initial campaign with 200,000 troops went badly.
