The ancient Chinese are credited with inventing biological warfare. In the 7th Century B.C., the fumigation of homes to kill pests gave the military the idea for chemical agents.

In one incident, an army was attempting to tunnel under the wall of a besieged city. The defenders heated up some bits of lime and used bellows to pump the smoke into the tunnel to defeat the attack.
