Pucture of Arthur Gonse Ilustr on 12/02/1898

Major General Charles-Arthur Gonse (19 September 1838, Paris – 18 December 1917, Cormeilles-en-Parisis), was Deputy Chief of Staff under the authority of General Raoul Le Mouton de Boisdeffre during the Dreyfus affair.

When confronted with overwhelming evidence that Ferdinand Walsin Esterhazy was guilty of the espionage for which Alfred Dreyfus had wrongfully been convicted, Gonse simply overlooked it and refused to recognize Dreyfus' innocence.
