Following the suppression of the uprising, the group began publishing the newspaper El Amigo del Pueblo, in which they denounced the CNT-FAI for "collaborationism", resulting in their expulsion from the organisation.
[7] On 15 March 1937, the Friends of Durruti Group was established by Felix Mártinez and Jaume Balius i Mir, who were associated with the CNT's newspaper La Noche [es].
[4] On 3 May, following an attack against the Telefónica building by the Communist-led Assault Guards, people throughout Barcelona began constructing barricades and a civil conflict erupted between government forces and the anarchists.
[15] The Friends of Durruti Group distributed leaflets among the barricades, demanding: the disarmament of the state's armed forces; the dissolution of all political parties that opposed them; the execution of the people responsible for the conflict; and the formation of a revolutionary junta,[16] in the form of a CNT-FAI-POUM government.
[20] The group's proposal for a Revolutionary Junta, which Spanish journalist Carlos Semprún noted to have only ever existed in "purely theoretical" terms, would have had anarchists and the POUM seize power from the Generalitat de Catalunya and shoot all of their opponents.
[18] For their abortive attempts to form a revolutionary junta, the Friends of Durruti were denounced as agent provocateurs by the CNT-FAI regional committees, who reiterated calls for a cease fire.
[35] Drawing from Mikhail Bakunin's proposal for a federated fighting force,[36] the group reiterated its calls for the establishment of a Revolutionary Junta, capable of managing the war effort and supervising the revolution.
[37] The pamphlet was taken by American Trotskyist Felix Morrow to amount to a "conscious break with the anti-statism of traditional anarchism", due to its advocacy of a revolutionary junta as an organ of power capable of overthrowing capitalism.
[38] Morrow's characterisation was disputed by the South African sociologist Lucien van der Walt, who claimed it instead to represent a "reaffirmation of the traditional perspectives of anarchism", pointing out its basis in anarcho-syndicalism.
[42] Bolshevik-Leninist leader Grandizo Munis himself later praised the group for evolving from anarchism to Marxism, comparing their idea of the revolutionary junta to those of the soviets, while also criticising them for lacking "political clarity".
