One of the most important weapons used during the Second World War was not a weapon used against people, but rather a drug used against disease. The wartime use of penicillin saved thousands of lives. In the First World War, for example, pneumonia killed eighteen percent of all the deaths in the United States army. In the Second World War, the rate went down to less than one percent. In addition, penicillin was instrumental in keeping wounds from getting infected and in helping to speed the healing process of those wounds that did become infected.
