By 1938, the Communist party was also in control of the newly created Military Investigation Service. The SIM was virtually dominated by Communist party members, allies and Soviet agents such as Aleksandr Mikhailovich Orlov and used as a tool of political repression. According to Basque nationalist Manuel de Irujo, "hundreds and thousands of citizens" were prosecuted by SIM tribunals and tortured in the SIM's secret prisons. Repression by the SIM as well as decrees which eroded Catalan autonomy by nationalizing the Catalan war industry, ports and courts caused widespread discontent in Catalonia amongst all social classes. Relations worsened between the Generalitat and the central government of Negrín, now based in Barcelona with the resignation of Jaime Aiguadé, representative of the Republican Left of Catalonia (ERC) party in the government and Manuel de Irujo, the Basque Nationalist minister. There was now widespread hostility amongst Republicans, Catalans, Basques and Socialists towards the Negrin government. As the Communists were forced to rely more and more on their dominance of the military and police, morale declined at the front as countless dissenting anarchists, republicans and socialists were arrested or shot by commissars and SIM agents.
