In its warfare against the States of Han and Zhao, the State of Qin employed calculated strategies suitable for the specific circumstances. For instance, it abandoned its original policy of crumpling the State of Han initially for pressing others to admit its supremacy. Its tactics were fully flexible ever since: attacking the State of Zhao when it turned weak, and besieging the State of Han at just the right moment.
Furthermore, after reviewing its strategies in the aftermath for its failure to conquer the State of Chu, it amasses its best army and arsenals in its subsequent assaults and finally sacked Chu. While in its campaign against the State of Qi, it avoided the head-on crashes with the main forces of Qi, but picked its weak link for surprise attacks.
On the other hand, the six other states grew weaker, fought individually and failed to form an alliance again the aggressions of Qin. During the attacks from Qin, the states could only fought off defensively, and this led to their demise one after the other by Qin's army.
