This was a desperate, all-or-nothing battle. Bingzhou had exhausted everything to strike at the Donghu Royal Court; it was a campaign where they could afford to win, but could not afford to lose.
This was also dictated by the scale of Bingzhou itself. Having been established for only a short time, Bingzhou simply lacked the national strength to engage in a protracted war of attrition with Donghu.
In other words, even if Donghu had failed in their attack this time, they could have waited for the next year, for the next opportunity. But for Bingzhou, a single failure meant the destruction of the state.
