Arrests of the POUM Leadership and Disappearance of Andreu Nin

The arrests of the POUM leadership and the disappearance of Andreu Nin become a measure of the Republic’s wartime fracture: a government fighting Franco also faces clandestine repression within its own camp, while the absence of reliable information turns political suspicion into a crisis of authority. Nin’s disappearance is not an isolated mystery in the novel but part of a broader landscape of unauthorized detention, factional conflict, and state violence whose methods recur in later regimes.

Background and Political Crisis

Manuel Arroyo returns from London to a Madrid where the consequences of the Barcelona May Days are already reshaping Republican politics. The clashes in Barcelona had left more than two hundred dead, all antifascists, and contributed to Largo Caballero’s fall and Juan Negrín’s rise to the premiership. What Manuel had not been told before his journey was that the POUM leadership had been arrested a few days earlier in what the narrative identifies as retaliation, or that Nin had been missing since the eighteenth. His disappearance was not merely unknown to the public: even the Republican government’s civilian intelligence services could not locate him.

The crisis unfolds amid competing authorities and distrust. Negrín describes the Military Intelligence Service as a nest of vipers, with Soviet influence, Communist acquiescence, and rivalries among the Socialists obstructing effective control. The Madrid Defense Junta had closed the city’s checas at the end of the previous year, yet illegal detention centers continued to operate beyond its supervision; when one was shut, another opened. In this account, the formal closure of detention sites does not end the practice. It makes the gap between public policy and clandestine coercion part of the political problem.

Arrests and Disappearance

The narrative presents the arrests of the POUM leadership as a retaliatory measure that could not safely be named as such in public. Nin’s disappearance compounds that silence: he has vanished from view, and the institutions that might establish what happened cannot find him. The lack of an acknowledged account leaves the fact of his absence politically potent, especially among Madrid’s small POUM community and its anarchist supporters.

The struggle over Soviet influence sharpens the stakes. Negrín says he would prefer to be rid of the Soviet advisers, but argues that expelling them would mean relinquishing the Soviet Union’s military aid—the Republic’s only source of aircraft, tanks, and heavy weapons. Without that support, continued resistance would amount to giving Spain to Franco. The government’s dependence on an indispensable ally therefore coexists with its inability, or unwillingness, to resolve the internal coercion and disappearance associated with the same political environment.

Madrid’s Divided Rear

By the time Manuel reaches Madrid, the political landscape is more severe than the one Negrín had described weeks earlier. Nin’s disappearance has enraged the city’s POUM supporters, few in number but backed by many anarchists. The Socialists are more numerous but deeply divided; Socialists and Communists together support the government in Valencia and the Madrid Defense Junta, yet that shared support is nearly their only point of agreement. The city’s wartime defense thus rests on alliances that are practical and fragile rather than settled.

This division gives Nin’s disappearance consequences beyond the fate of one political leader. It intensifies the anger of one faction, strains cooperation among groups defending the besieged city, and makes the Republic’s internal security apparatus appear compromised by forces it cannot clearly command. The question of who is responsible remains bound to the same fractured system that makes dependable information so difficult to obtain.

Secret Detention and the Afterlife of the Method

The novel later shows the practical logic of secret detention in an episode involving a wounded man found by soldiers near El Pardo. Mistaken for a corpse, he is taken to the infirmary. A credential identifies him as Rafael Cuesta Sánchez, a delegate to the Madrid Defense Junta, and a police commissioner telephones the commander with instructions: if Rafael is dead, bury him as an unknown person and enter him in no register; if he is alive, save him at any cost, but do not admit him to a hospital under his own name, because someone may try to kill him again. The commissioner offers no explanation beyond saying that Rafael is vital to the Republic. The scene makes the machinery of concealment concrete: survival itself depends on evading official records and preventing another attack.

The later comparison with Argentina distinguishes the events rather than collapsing them into one history. In 1975, Isabel Perón’s government begins Operation Independence, ostensibly against guerrillas in Tucumán but used to divide the country into military zones and authorize repression against civilians. After the 1976 coup, the military dictatorship develops clandestine detention, forced disappearance, torture, execution, corpse disposal, and the theft and reassignment of children into a systematic apparatus. The novel also recalls that in Madrid, unregistered dead could be buried as unknowns; by the end of the 1940s, an unidentified body with a gunshot wound to the neck is nevertheless recorded as a routine cardiorespiratory arrest and sent to a mass grave at La Almudena Cemetery. These recurring acts of erasure give Nin’s disappearance a wider narrative resonance: the suppression of a person’s fate and the suppression of the evidence of violence become linked instruments of political power.
