During the same year, he was elected to the chamber as member for Angoulême. He was expelled from the chamber in 1890 for interrupting debates. He did not campaign for the election of 1893, but was re-elected in 1898, and distinguished himself by his vehemence as a nationalist and anti-Dreyfusard. After the funeral of President Félix Faure, on 23 February 1899, he endeavoured to persuade General Gaudérique Roget to lead his troops to the presidential palace. After the general and his troops first ignored and then dismissed Déroulède, he demanded to be arrested for treason. During his trial, Déroulède declared that if released he would continue his insurrectionary activity. He was triumphantly acquitted on 31 May, and on 12 August was again arrested and accused, together with André Buffet, Jules Guérin and others, of conspiracy against the republic. After a long trial before the French Senate serving as the high court, he was sentenced, on 25 January 1900, to ten years' banishment from France, and retired to San Sebastián in Spain.
