Biochemical Attack: Past Incidents

There have been very few uses of biological or chemical attacks recorded. Here are a few of those attacks:

1900-1945
The German armies in both the First and Second World Wars used mustard gas to inflict painful burns on Allied troops, severely limiting closer combat.
1972-1977
The United States sprayed napalm on Vietnam as a chemical fuel solution to destroy unexposed jungle areas during the Vietnam War. Thousands were affected through destruction of homes and death.
