During World War II, one of the "spoils of war" is the world supply of quinine.
Date: 1942
The majority of the world's supply of quinine is grown in Southeast Asia. As a result of the war, 95% of the world's supply of quinine falls into the hands of Japan and Germany. As a result, soldiers in the Allied Forces stationed in Asia don't have access to quinine, and are therefore vulnerable to malaria. A significant percentage of Allied soldiers are weakened by malaria. This lack of access to quinine is blamed as leading to the surrender of U.S. and Filipino forces to the Japanese at Batan.
