Mustard Gas

Deadly Mustard Gas

World War 1 is the first war that saw the use of chemical weapons in modern warfare. The main chemical weapon used was mustard gas. Mustard gas killed thousands of soldiers who where stuck in trenches. Gas masks where given to all soldiers in the second half of the war in order to withstand chemical attacks. Poison gas is today a banned substance in warfare and World War 1 is a clear reminder why.

Question:

Name one other gas used in World War 1 other than mustard gas.
