Immediately after the events, the public prosecutor in Nîmes got to work to trace witnesses. He investigated 70, including 17 Italians, and opened 41 files leading to indictments against 17 accused, only eight of whom had previous criminal records. Charges were laid on 10 September and, at the request of the prosecutor, the
Cour de Cassation agreed to hold the trials in
Angoulême. Among the defendants was an Italian worker, Giordano, defended by M. Guillibert, a lawyer from Aix. The trial was due to open on 11 December 1893 but due to the complexity of the case, it was not actually started until 27 December. As the trial progressed, it became clear that convictions were unlikely. The
New York Times reported that "Evidence in the trial is extremely perplexing and suggests wholesale perjury on both sides. What the result ought to be nobody has the slightest idea, but it is taken for granted that a French jury will not punish French citizens, and that Italy will be supplied with a large and valuable grievance." One defendant, Barbier, who had previously admitted playing an active part in the events of 17 August, totally retracted his evidence and claimed he had never been there. Despite the efforts of the court, it was impossible to get from him anything other than abject denials. A French worker, Vernet, supposedly stabbed in the stomach and the side by an Italian, had not answered a witness summons. The prosecutor sent for him by telegraph. The following day, a 30-year-old Vernet was called to the stand and asked if he had been stabbed. He replied, "I wasn't stabbed. I didn't even go to the saltpans at Aigues-Mortes." Asked if he was, indeed, Vernet from
Saint-Laurent-du-Pont, he replied "Certainly, but I'm a telegram postman in Grenoble and I have never set foot in the saltpans. I know another Vernet in Saint-Laurent-du-Pont and it's my uncle, a man of fifty years, a cultivator who has never left the land." The court decided that someone had given a false name. On 30 December, the jury retired to consider its verdict, returning to acquit all the prisoners. When the latter rose to thank the jury, the audience in the courtroom cheered and applauded them. == Reactions to the trial ==
