Dreyfus came from a wealthy Jewish family. His intellectual arrogance and aloofness earned him the mistrust of many of his colleagues. Many of the officers of the General Staff were anti-semitic and the only reason Dreyfus made it into his position was because of his intelligence and high grades in the Ecole de Guerre.
"His rather introverted character, the tactless display which he made of both his intelligence and his personal wealth, even his professional curiosity all contributed to make him suspect of a guilt to which, in the eyes of many, his race predestined him."
The case against Dreyfus during the affair was completely mishandled through tampering of evidence and corruption in the military. General Mercier was only able to open official proceedings because of pressure from the media and the gravity of the affair.
"It was the press which created the Affair and made truce impossible."
The People were looking for someone to blame for writing the bordereau and Dreyfus was the perfect candidate. Right from the beginning the case was mishandled. Handwriting experts were handpicked by Mercier to make a correlation between the writing of the bordereau and that of Dreyfus even though none should have been found.
"So he was determined to obtain Dreyfus's conviction at any price."
