On 24 February, Stalin forbade the sending of Soviet volunteers to fight in Spain,[4] but he did not recall Alexander Orlov, an Order of Lenin awardee from the NKVD (secret police).[citation needed] Orlov and the NKVD orchestrated the May Days, the conflict that erupted between 3 and 8 May in Barcelona between the Popular Front and the Trotskyist Workers' Party of Marxist Unification (POUM).[5] The battle resulted in approximately 1,000 fighters being killed and 1,500 injured, though estimates vary.[6][7] Following the suppression of the POUM, any possibility of Spain serving as a refuge for Leon Trotsky was eliminated.[citation needed] Orlov employed the same methods of terror, duplicity, and deception used during the Great Purge (1936–1938).[citation needed]
