After the trial of Émile Zola for publishing his 1898 open letter "J'Accuse…!", Picquart was himself accused of forging the note that had convinced him of Esterhazy's guilt. He was then arrested for forgery and was waiting for a court-martial, while the French Court of Cassation was reviewing the Dreyfus case. After the second court-martial, held as a consequence of the conclusions of the court, Picquart resigned from the army. However, the exoneration of Dreyfus in 1906 also absolved Picquart, who was, by an act of the French Chamber of Deputies, promoted to brigadier general. That was the rank that an officer of his seniority and experience could normally have expected to reach, if his career had not been interrupted by his involvement in the Dreyfus affair.
