Battles change the course of history, they win wars, they topple thrones and redraw borders. Battles have been a part of human history since the beginning of time. They are an intricate part of wars and the events that set the path of events to follow, as instruments molding the future.

By deciding which group, nation or alliance that ends up victorious, they influence the spread of ideology, culture, civilization and religious dogma. Some battles are not directly influential on the path of history on their own, but rather, influential as instruments of propaganda with an impact on public opinion.

The Warring States period was a period in ancient China when the Kingdom of Qin would unify China under the Qin dynasty. The political landscape in China previous to the unification was split between seven major states, Qin, The Three Jins, Qi, Chu, and Yan.

Most armies in the Warring States period consisted of a combination of infantry and cavalry, and the earlier use of chariots gradually fell into disfavor.

The weapons and armor for soldiers gradually changed during the war, from using weapons out of bronze, to iron. So-called ‘Dagger-axes’ were common, and the Qin who produced 18-foot-long pikes.

This was also around the time when the legendary military strategist Sun Tzu wrote The Art of War ( 孫子兵法). It presents a philosophy of war for managing conflicts and winning battles. It is accepted as a masterpiece on strategy and has been frequently cited and referred to by generals and theorists.

All warfare is based on deception. Hence, when we are able to attack, we must seem unable; when using our forces, we must appear inactive; when we are near, we must make the enemy believe we are far away; when far away, we must make him believe we are near.

– Sun Tzu

Towards the end of the Warring States Period, the state of Qin had become more powerful compared to the other six states. This resulted in policies of the other six states to become more oriented towards dealing with the Qin threat together. It was largely unsuccessful, however, as the Qin was victorious in battle after battle; as Qin conquered the Shu area in 316 BCE, in 293 BCE. the Battle of Yique between Wei allied with Han resulted in a victory for the Qin, Qin attacked the Chu in In 278 BCE and captured their capital city, Ying and in 260 BCE, the Battle of Changping was fought between the Qin and the Zhao.

Zhao Kuo commanded an army of approximately 400,000 men. Zhao Kuo was to meet the Qin army in the field but attacked the Qin camp in what was to be a surprise attack. The Qin general Bai Qi responded with a Cannae-like maneuver with his estimated 550,000 soldiers. Just as Hannibal did against the Romans at the Battle of Cannae, the Qin army withdrew at the center, toward the Qin fortress, drawing Zhao Kuo after them, then a body of 25,000 cavalries and 5,000 light cavalries with bows and crossbows remained behind to spring the trap.

With the enemy trapped, Bai Qi launched a counterattack. The Zhao army was split in two and its supply lines cut. The forces dug down for siege warfare but the Zhao army finally surrendered after 46 days of siege.

Bai Qi ordered the captured soldiers to be executed. The Chinese ancient historian Sima Qian claimed that over 450,000 Zhao soldiers were killed during and after the battle. The battle would mark the definite defeat of all other kingdoms and Qin to gain military dominance over the other states. And in 221 BCE, the Qin would use this dominance to unify China.
