Jacques Gernet claims that the Zhou dynasty, which conquered the Shang ca. 1046 BC, made more use of the chariot than did the Shang and "invented a new kind of harness with four horses abreast". The crew consisted of an archer, a driver, and sometimes a third warrior who was armed with a spear or dagger-axe. From the 8th to 5th centuries BC the Chinese use of chariots reached its peak. Although chariots appeared in greater numbers, infantry often defeated charioteers in battle.
