French intelligence discovered someone had been passing military secrets to the German Embassy. Senior officers began to suspect Dreyfus, though there was no direct evidence of any wrongdoing. Dreyfus was court-martialed, convicted of treason, and sent to Devil's Island in French Guiana. Lt. Col. Georges Picquart came across evidence that implicated another officer, Ferdinand Walsin Esterhazy, and informed his superiors. Rather than move to clear Dreyfus, the decision was made to protect Esterhazy and ensure the original verdict was not overturned. Major Hubert-Joseph Henry forged documents that made it seem as if Dreyfus were guilty, while Picquart was reassigned to duty in Africa. However, Picquart's findings were communicated by his lawyer to the Senator Auguste Scheurer-Kestner, who took up the case, at first discreetly and then increasingly publicly. Meanwhile, further evidence was brought forward by Dreyfus's family and Esterhazy's estranged family and creditors. Under pressure, the general staff arranged for a closed court-martial to be held on 10–11 January 1898, at which Esterhazy was tried in camera and acquitted. Picquart was detained on charges of violation of professional secrecy. In response Zola risked his career and more, and on 13 January 1898 published J'Accuse…! on the front page of the Paris daily L'Aurore. The newspaper was run by Ernest Vaughan and Georges Clemenceau, who decided that the controversial story would be in the form of an open letter to the President, Félix Faure. Zola's J'Accuse...! accused the highest levels of the French Army of obstruction of justice and antisemitism by having wrongfully convicted Alfred Dreyfus to life imprisonment on Devil's Island. Zola's intention was that he be prosecuted for libel so that the new evidence in support of Dreyfus would be made public. The case, known as the Dreyfus affair, deeply divided France between the reactionary army and Catholic church on one hand, and the more liberal commercial society on the other. The ramifications continued for many years; on the 100th anniversary of Zola's article, France's Roman Catholic daily paper, La Croix, apologised for its antisemitic editorials during the Dreyfus affair. As Zola was a leading French thinker and public figure, his letter formed a major turning point in the affair. Zola was brought to trial for criminal libel on 7 February 1898, and was convicted on 23 February and removed from the Legion of Honour. The first judgment was overturned in April on a technicality, but a new suit
