4) The Dreyfus Affair
Alfred Dreyfus served for the French military as an artillery officer, until he was charged with treason in October of 1894. This happened after information about new military technology was somehow acquired by the Germans. People were accusing Dreyfus of leaking the information from all sides, while others believed that Dreyfus was actually innocent and was being used as a scapegoat because of his Jewish heritage.
It turns out the suspicions were true, and Dreyfus was just an incredibly unlucky fall boy set up by the real traitor: Major Ferdinand Walsin Esterhazy. Dreyfus later re-entered the military during World War I.
