Solidaridad internacional

Solidaridad internacional—international solidarity—is more than an ideal voiced in wartime Madrid: it is a practice of crossing borders, sharing resources, and acting for people whose lives are imperiled. Its most vivid embodiment is Norman Bethune’s Canadian medical mission, which brings refrigerated blood transfusion to the besieged city. Across the novel, however, solidarity is neither secure nor evenly honored. The labor that saves lives stands against political division, diplomatic retreat, and the successive exiles of people left to bear the consequences of international choices.

A medical mission made material

Bethune reaches Madrid on 14 December 1936 after weeks of effort to secure his government’s support and raise funds, then an exhausting journey across the Atlantic and France and through a country divided by war. His arrival at Príncipe de Vergara 36 marks the fulfillment of a long-pursued aim: to put Canadian assistance at the service of the Madrid Defense Council and the Republican government. The former residence of a German diplomat becomes an improvised medical laboratory, its rooms rapidly cleared for equipment and supplies. A refrigerator, an autoclave, sterilizers, surgical instruments, blood containers, and serum turn a luxurious apartment into a working institution.

The practical meaning of the mission lies especially in its portable equipment. Bethune’s fifteen packs contain supplies for transfusion away from the laboratory, including saline solution, glucose solution, and sterilized instruments. The innovation is not only that blood can be stored under refrigeration; it is that donor and recipient no longer need to be physically connected at the bedside. Medical aid can travel toward the wounded rather than requiring the wounded to reach a donor. In a city under siege, solidarity takes the form of a method designed to make help more usable where it is needed.

The transfusion and its human measure

At a field hospital in Casa de Campo, Bethune tests a soldier’s blood group and begins transfusing stored blood. The first bottle does not suffice; after a second, the apparently dead man opens his eyes and smiles at his rescuer. The account presents the moment not as an abstract technical breakthrough but as a life returned in stages, with the medical work and the patient’s response inseparable. That morning, Bethune’s intervention revives twelve soldiers at the Hospital de Sangre de la Casa de Campo.

The first survivor’s name is not known. His companions mark his return to life by placing a lit cigarette in his mouth, and the hospital ward erupts in celebration. Their cheers join Canada, Bethune, the Republic, the working class, and international solidarity in one outpouring of gratitude. The revived soldier adds his own contribution, crying, “¡Viva yo!” Bethune does not understand the words, but the scene makes the exchange legible without translation: the patient’s survival is at once his own victory and a communal event. The unknown soldier is not reduced to a statistic; his first act back among the living gives the rescue a voice and a measure of joy.

The novel also stresses the scale and duration of Bethune’s contribution. His work saves thousands of soldiers in the People’s Army of the Spanish Republic during the civil war, and the technique will benefit millions afterward. That later reach gives the Madrid mission a double significance: it answers an immediate emergency while creating a practical means of preserving life well beyond the original setting. The medical gift is international in origin and in consequence, but its first meaning remains grounded in the wounded soldiers who need it.

Commitment amid division and danger

The Canadians’ visible commitment accompanies the narrator’s journey with Bethune’s group toward Majadahonda. They travel in the blue overalls worn by Republican militiamen, while the narrator is the only Spaniard in the truck who is himself a Republican. Far from making him uncomfortable, the volunteers’ clothing reassures him. Their allegiance is not hidden in private sympathy; it is declared in what they wear as they travel through a landscape devastated by bombing. Along the road, refugees carry household remnants, bedding, and children past smoking ruins. The scene places international commitment beside the human cost it cannot erase: volunteers can offer aid, but they cannot undo the destruction that has driven civilians from their homes.

Solidarity is also tested by the fractured politics of the Republican side. In a conversation about Soviet advisers, the head of government recognizes that dependence on Soviet military assistance constrains the Republic’s choices: without aircraft, tanks, and heavy weapons, breaking with the Soviet Union could amount to surrendering Spain to Franco. He invokes the brigadistas and Mexican rifles as forms of support, but the account makes clear that affection and limited supplies cannot substitute for the military aid on which the government depends. Shared commitment thus exists within unequal political conditions, and the need to survive can force painful compromises.

Jan Schmitt’s friendship with Adrián Gallardo offers a further, troubling contrast between personal loyalty and ideological solidarity. Jan is described as generous, brave, loyal to his comrades, and willing to risk his life for the weak, yet he also holds a fierce hatred rooted in an inherited grievance. He appeals to supposed scientific truth to defend the idea that Slavs are inferior, while Adrián struggles to reconcile that belief with Jan’s tenderness and courage. The episode shows how solidarity among individuals can coexist with exclusionary political ideas: battlefield generosity does not, by itself, dissolve the prejudices that define who is considered fully human.

Exile and the limits of international protection

After the Republic’s defeat, solidarity appears in the networks and modest acts that help exiles endure, but it is repeatedly constrained by displacement. In the summer of 1939, Manuel Arroyo lives in Geneva in markedly reduced circumstances. Pablo de Azcárate has found him unofficial work through contacts at the League of Nations: Arroyo meets representatives of neutral and allied countries under an assumed name, then sends reports to Taplow when he can find space on a British military aircraft. The job is lonely and poorly paid, yet it gives him safety in Switzerland and a room in a pension. He knows that this relative security would be a privilege to many Spanish exiles, while admitting that he would exchange it for the exposed, harsher conditions of a French camp.

When Arroyo enters Spain through Gibraltar on 10 September 1946, his American passport supplies a cover identity for a return driven by attachment to his parents’ homeland. He sees the Campo de Gibraltar from a British military aircraft and recognizes the rooftops of La Línea, but cannot openly reveal what the country means to him. The border crossing captures the split between the person he is and the identity he must present to move safely. International networks enable his passage, yet he remains dependent on concealment and on a foreign official who must see him as an American visiting the country of his parents.

The account of postwar diplomacy sets that personal concealment within a wider abandonment. Arroyo predicts that the United Nations will condemn Franco without imposing an economic blockade, threatening military action, or invading Spain. He argues that the democratic powers are already rewriting the recent war to emphasize the Normandy landings and diminish the Soviet campaign, while former Nazis are rumored to be escaping custody and being recruited for anti-Soviet work. In this shifting climate, Franco’s anticommunism may matter more to foreign governments than their stated opposition to his rule. The resulting contrast is stark: international solidarity helped sustain resistance to fascism, but the emerging Cold War makes support for Spanish democrats less compelling to the powers whose backing might have changed their fate.

The novel extends that pattern into later exile. By December 1948, Clara Stauffer arrives in Buenos Aires with a welcoming committee of six men and three women, greeting them by name and asking after their families. Arroyo accompanies her while already trying to distance himself from the network around her. This carefully organized reception contrasts with the vulnerable movements of Republican exiles: international connections can provide hospitality and coordination, but they do not serve every cause or every displaced person alike. The scene makes solidarity a matter of who is welcomed, by whom, and for what purpose—not an automatic consequence of crossing a border.

The Argentine dictatorship brings the cost of that unevenness into a later historical frame. Its clandestine machinery of detention, torture, killing, disappearance, and stolen children drives thousands of people to seek refuge after the coup of 24 March 1976. Mexico receives the largest number of exiles; Spain, paradoxically, is the second-largest destination, soon after Franco’s death. For Republican Spaniards who had built new lives in South America after their own exile in 1939, the new flight reverses the earlier route: nearly forty years later, they return to Spain as foreigners, with nothing. The sequence links generations through displacement without pretending that their circumstances are identical. It also tests the promise of international solidarity against recurring political violence and the repeated demand to begin again elsewhere.

A promise measured by action

The novel’s strongest image of international solidarity remains Bethune’s medical work: a refrigerated bottle of blood, carried by a Canadian doctor into a besieged city, restores a soldier whom those around him had given up for dead. The episode gives the ideal a concrete form—equipment, travel, trained labor, and a second bottle when the first is not enough. Its public celebration joins the rescued man’s own claim to life with the political community and foreign volunteers who helped make that life possible.

Yet the later passages keep that moment from becoming a guarantee of historical rescue. Refugees move past the volunteers’ truck; political factions weaken a government dependent on foreign arms; exiles rely on improvised contacts and assumed identities; and postwar powers retreat from the commitments their earlier struggles seemed to promise. The recurring pattern is therefore both generous and severe: people act across borders to preserve life, while states and institutions can narrow, redirect, or abandon that effort. International solidarity matters in the book not because it always prevails, but because the soldier’s smile, the volunteers’ journey, and the refugees’ onward movement show exactly what is at stake when it does not.
