Spanish Civil War

Map of the Spanish Civil War (1936–1939)

The Spanish Civil War was a major conflict fought in Spain from 17 July 1936 to 1 April 1939. It began after a military rebellion by a group of conservative generals led by Francisco Franco against the elected Government of the Second Spanish Republic, then under the leadership of President Manuel Azaña. The rebel coup was supported by the conservative groups including the Spanish Confederation of the Autonomous Right (Confederación Española de Derechas Autónomas, or CEDA), monarchists known as Carlist groups, and the Fascist Falange (Falange Española de las JONS). Following the only partially successful coup — important cities like Madrid, Barcelona, Oviedo, Bilbao, Badajoz, and Málaga did not join in the rebellion as did Morocco, Pamplona, Burgos, Valladolid, Cádiz, Cordoba, Seville, and Jerez — Spain was left militarily and politically divided. From that moment onwards General Franco began a protracted war of attrition against the legally established government, as loyalist supporters of the centre-left Republican Government fought the rebel forces for control of the country. There were bloody purges in every piece of territory conquered from the republic in order to consolidate Franco’s future regime, and purges done by the communist republicans during the war. The War ended with the victory of the rebels, who called themselves ‘Nationalists’, the overthrow of the Republican Government, and the exile of thousands of Spanish Republicans, many of whom ended up in refugee camps in Southern France. With the establishment of a conservative dictatorship led by General Francisco Franco in the aftermath of the Civil War, all right-wing parties were fused into the structure of the Franco regime.

The conservative generals (nacionales) received the support of Nazi Germany and the Fascist Italy, as well as neighbouring Portugal. The Soviet Union intervened in support of the socialist Republicans, although it encouraged factional conflict to the benefit of the Soviet foreign policy, and its actions may have been detrimental to the Republican war effort as a whole. Hispanist Hugh Thomas: “Had they been able to purchase and transport good arms from US, British, and French manufacturers, the socialist and republican members of the Spanish government might have tried to cut themselves loose from Stalin.” The American Government offered no official support for either side, although over 2,000 Americans volunteered on the Republican side. Meanwhile, American corporations such as Texaco, General Motors, Ford Motors, and The Firestone Tire and Rubber Company greatly assisted the Nationalist army, furnishing a regular supply of trucks, tires, machine tools, and fuel. The new tank warfare tactics and the terror bombing of cities from the air were features of the Spanish Civil War which played a significant part in the later general European war.

The Spanish Civil War has been dubbed “the first media war,” with several writers and journalists wanting their work “to support the cause.” Foreign correspondents and writers covering it included Ernest Hemingway, Georges Bernanos, Martha Gellhorn, César Vallejo, George Orwell, Arthur Koestler, Halfdan Rasmussen, and Robert Capa. Like most international observers, they tended to support the Republicans, with some, such as Orwell, participating directly in the fighting.

Like most civil wars, it became notable for the passion and political division it inspired. The Spanish Civil War often pitted family members, neighbors, and friends against each other. Apart from the combatants, many civilians were killed for their political or religious views by both sides, and after the War ended in 1939, the losing Republicans were persecuted by the victorious Nationalists.

An estimated total of 500,000 people lost their lives as a consequence of the War.

Prelude to war
Historical context
There were several reasons for the war, many of them having roots in long-standing tensions that had escalated over the years.

The 19th Century was a turbulent time for Spain. The country had undergone several civil wars and revolts, carried out by both reformists and the conservatives, who tried to displace each other from power. A liberal tradition that first ascended to power with the Spanish Constitution of 1812 sought to abolish the monarchy of the old regime and to establish a liberal state. The most traditionalist sectors of the political sphere systematically tried to avert these reforms and to sustain the monarchy. The Carlists — supporters of Infante Carlos and his descendants — rallied to the cry of “God, Country and King” and fought for the cause of Spanish tradition (Patrilineality monarchy and Catholicism) against the liberalism – and later, the republicanism – of the Spanish governments of the day. The Carlists, at times (including the Carlist Wars), allied with nationalists (not to be confused with the nationalists of the Civil War) attempting to restore the historic liberties (and broad regional autonomy) granted by the fueros (regional charters) of the Basque Country and Catalonia. Further, from the mid-19th century onwards, liberalism was outflanked on its left by socialism of various types and especially by anarchism, which was far stronger in Spain than anywhere else in Europe.

Spain was governed under a number of different systems in the period between the Napoleonic wars of the early 19th Century and the outbreak of the Civil War. During most of the 19th Century, Spain was a constitutional monarchy, but in 1873, the King (Amadeo I) abdicated due to increasing political pressure. The First Spanish Republic that emerged was short-lived. A monarchy under Alfonso XIII lasted from 1887 to 1931, but from 1923 was held in place by the military dictatorship of Miguel Primo de Rivera. Following the overthrow of Primo de Rivera in 1930, the monarchy was unable to maintain power and the Second Spanish Republic was declared in 1931. This Republic soon came to be led by a coalition of the left and center. A number of controversial reforms were passed, such as the Agrarian Law of 1932, distributing land among poor peasants. Millions of Spaniards had been living in poverty under the firm control of the aristocratic landowners in a quasi-feudal system. These reforms drew strong opposition from landowners and aristocrats. At the same time, the anti-clericalist acts of the Government infuriated the clergymen, while military cutbacks and reforms further alienated the military.

Constitution of 1931 and anti-clericalism
On 14 April 1931, Spain declared itself a Second Republic and ended the monarchy. A meeting of the Spanish Parliament drew up a new constitution, which was adopted on 9 December 1931, after being passed by a referendum three days earlier. The Spanish Constitution of 1931 meant the legal beginning of the Second Spanish Republic, in which the election of both the positions of Head of State and Head of government was to be democratic.

The 1931 Constitution was formally effective from 1931 until 1939; in the spring of 1936, however, at the onset of the Spanish Civil War, it was largely abandoned by the Republicans in favor of leftist revolution – “the revolution … initiated … in response to, and as a result of, the counter-revolutionary revolt of the military.”

With the appearance of a Republic, after the revolutionary events of the municipal elections in 1931, Spain “embraced constitutional democracy.” Yet the “definition of the Republic was always ambiguous. Never a single movement, [it encompassed] liberals, radicals, federalists, and even early anarchists. The Socialist Party was Republican, but only as part of a wider political program. And to convinced monarchists, the Republic was an anathema – the Carlist militias were training in the mountains as early as 1931. The conservative Republican Ángel Ossorio y Gallardo recalled that mothers would reproach a child’s untidiness with the words, ‘This looks like a Republic!’.” The issues of private property, of land expropriation for reasons of social utility, of religion, -all were areas for competing claims. The constitution provided for universal suffrage and generally accorded thorough civil liberties and representation, while also removing any special Catholic rights. The Constitution proclaimed religious freedom and a complete separation of Church and State. Catholic schools continued but outside the state system, and in 1933 further legislation banned all monks and nuns from teaching. “The new Republican nation was , in a sense, to be legislated into existence. But it was also to be created through a system of state education, which would be secular, obligatory, free of charge, and available to all. The Republic regulated Church use of property and investments, provided for recovery and controls on the use of property the Church had obtained during past dictatorships, and banned the Vatican-controlled Society of Jesus. It was the controversial articles 26 and 27 of the constitution which strictly controlled Church property and prohibited religious orders from engaging in education. “Religion was to be confined to the private sphere, forcibly if need be; the public world of the Republic was resolutely secular.” Supporters of an established Church, and even a liberal advocate of separation of church and state like Jose Ortega y Gasset, considered the articles overreaching, – “the article in which the Constitution legislates the actions of the Church seems highly improper to me.”

Some conservatives also blamed the government for failing to suppress widespread anti-Catholic sentiment among ordinary citizens and sometimes-violent protests at monasteries. Catholics mustered their forces in opposition, exacerbating the conditions that led to the war. As early as October 1931 Gil Robles the leading spokesman of the parliamentary right maintained that the constitution was ‘born dead’ – a ‘dictatorial Constitution in the name of democracy.’

On 3 June 1933, in the encyclical Dilectissima Nobis (On Oppression Of The Church Of Spain), Pope Pius XI condemned the Spanish Government’s deprivation of the civil liberties on which the Republic was supposedly based, noting in particular the expropriation of Church property and schools and the persecution of religious communities and orders.

Commentators have posited that the “hostile” approach to the issues of church and state was a substantial cause of the breakdown of democracy and the onset of civil war. Since the far left considered moderation of the anticlerical aspects of the constitution as totally unacceptable, the commentator Stanley Payne has argued that “the Republic as a democratic constitutional regime was doomed from the outset”.

1933 election and aftermath
In the 1933 elections to the Cortes Generales, the Spanish Confederation of the Autonomous Right (Confederación Española de Derechas Autónomas or CEDA) won a plurality of seats; however, these were not enough to form a majority. Despite the results, then President Niceto Alcalá-Zamora declined to invite the leader of the CEDA to form a government and instead invited the Radical Republican Party and its anticlerical leader Alejandro Lerroux to do so. CEDA supported the Lerroux government; it later demanded and, on 1 October 1934, received three ministerial positions.

Lerroux’s alliance with the right, his suppression of the revolt in 1934, and the Stra-Perlo scandal combined to leave him and his party with little support going into the 1936 election; Lerroux lost his seat in parliament.

Rising tensions and political violence
Hostility between the left and the right increased after the 1933 formation of the Government. Spain experienced general strikes and street conflicts. Noted among the strikes was the miners’ revolt in northern Spain and riots in Madrid. Nearly all rebellions were crushed by the Government and political arrests followed.

Tensions rose in the period before the start of the war. Radicals became more aggressive, and conservatives turned to paramilitary and vigilante actions. According to official sources, 330 people were assassinated and 1,511 were wounded in political violence; records show 213 failed assassination attempts, 113 general strikes, and the destruction (typically by arson) of 160 religious buildings.

1936 Popular Front victory and aftermath
In the 1936 Elections a new coalition of Socialists (Spanish Socialist Workers’ Party, PSOE), left-liberals (Republican Left and the Republican Union Party), Communists, and various regional nationalist groups won the extremely tight election. The results gave 34 percent of the popular vote to the Popular Front and 33 percent to the incumbent government of the CEDA. This result, when coupled with the Socialists’ refusal to participate in the new government, led to a general fear of revolution.

Azaña becomes president
Without the Socialists, Prime Minister Manuel Azaña, a liberal who favored gradual reform while respecting the democratic process, led a minority government. In April, parliament replaced President Niceto Alcalá-Zamora with Azaña. The removal of Zamora was made on specious grounds using a constitutional technicality. Although the right also voted for Zamora’s removal, this was a watershed event which inspired many conservatives to give up on parliamentary politics. Azaña had found that by spring of 1936 the left was using its influence to circumvent the Republic and the constitution and was adamant about increasingly radical changes. Leon Trotsky wrote that Zamora had been Spain’s “stable pole”, and his removal made the climate revolutionary.

Azaña was the object of intense hatred by Spanish rightists because he had pushed a reform agenda through a recalcitrant parliament in 1931–1933. Joaquín Arrarás, a friend of Francisco Franco, called him “a repulsive caterpillar of red Spain.” The Spanish generals particularly disliked Azaña because he had cut the army’s budget and closed the military academy while war minister (1931). CEDA turned its campaign chest over to army plotter Emilio Mola. Monarchist José Calvo Sotelo replaced CEDA’s Gil Robles as the right’s leading spokesman in parliament.

Murder of Calvo Sotelo
José Calvo Sotelo was the leading Spanish monarchist and a prominent parliamentary conservative. He protested against agricultural reforms, expropriations, and restrictions on the authority of the Catholic church, which he considered Bolshevist and anarchist. He instead advocated the creation of a corporative state.

On 12 July 1936, in Madrid, a right-wing group murdered Lieutenant José Castillo of the Guardia de Asalto police force, which was given the task of addressing urban violence. Castillo was a member of the Socialist party. The next day, the Assault Guards officers arrested Calvo Sotelo. Calvo Sotelo is said to have been killed sometime thereafter by Guardia de Asalto officer Luis Cuenca.

The killing of Sotelo, a prominent member of parliament, with involvement of the police, aroused suspicions and strong reactions among the government’s opponents on the right. Although the conservative Nationalist generals, with a plane en route to take Francisco Franco to the Army of Africa, were already in advanced stages of a planned uprising, the event provided a catalyst and convenient public justification for their coup.

Outbreak of the war

The monarchist General José Sanjurjo was the figurehead of the rebellion, while General Emilio Mola was chief planner and second in command. Mola began serious planning in the spring, but General Francisco Franco hesitated until early July, inspiring other plotters to refer to him as “Miss Canary Islands 1936″. Franco was a key player because of his prestige as a former director of the military academy and as the man who suppressed the Socialist uprising of 1934.

Fearing a military coup, Prime Minister Casares Quiroga sent General Manuel Goded Llopis to the Balearic Islands and Franco to the Canary Islands. On 17 July 1936, the plotters signaled the beginning of the coup by broadcasting the code phrase, “Over all of Spain, the sky is clear.” Goded and Franco immediately took control of the islands to which they were assigned. Warned that a coup was imminent, leftists barricaded the roads on 17 July, but Franco avoided capture by taking a tugboat to the airport.

Two British MI6 intelligence agents, Cecil Bebb and Major Hugh Pollard, then flew Franco to Spanish Morocco to see Juan March Ordinas, where the Spanish Army of Africa, led by Nationalist officers, was unopposed.

Government reaction
The rising was intended to be a swift coup d’état, but the government retained control of most of the country. The rebels failed to take any major cities—in Madrid they were hemmed into the Montaña barracks. The barracks fell the next day, with much bloodshed. Republican leader Santiago Casares Quiroga was replaced by José Giral who ordered the distribution of weapons among the civilian population. This facilitated the defeat of the army insurrection in the main industrial centers, including Madrid, Barcelona, Valencia and other main cities in the Mediterranean area, but it allowed the anarchists to arm themselves and take control of Barcelona and large swathes of Aragon and Catalonia, so that the control of the Republican Government in those areas became tenuous at best throughout the ensuing conflict.

Meanwhile the Army of Africa crossed the Gibraltar Strait and met General Queipo de Llano’s forces in Sevilla. Their quick movement allowed them to meet General Mola’s Northern Army and secure most of northern and northwestern Spain, as well as central and western Andalusia.

The Republican Government ended up with controlling almost all of the Eastern Spanish coast and central area around Madrid, as well as Asturias, Cantabria and part of the Basque Country in the north.

Combatants
The war was cast by Republican sympathizers as a struggle between “tyranny and democracy”, and by Nationalist supporters as between Communist and anarchist “red hordes” and “Christian civilization”. Nationalists also claimed to be protecting the establishment and bringing security and direction to an ungoverned and lawless society.

The active participants in the war covered the entire gamut of the political positions of the time. The Nationalist (nacionales) side included the Carlists and Legitimist monarchists, Spanish nationalists, the Falange, and most conservatives and monarchist liberals. Virtually all Nationalist groups had very strong Catholic convictions and supported the native Spanish clergy. On the Republican side were Marxists, socialists, liberals, and anarchists.

Spanish politics, especially on the left, were quite fragmented. At the beginning, socialists and radicals supported democracy, while the communists and anarchists opposed the institution of the republic as much as the monarchists. There were internal divisions even among the socialists: a group that adhered to classical Marxism, and a more progressive Marxist group. The former was the Spanish Socialist Workers’ Party (PSOE), one of whose delegates to the Soviet Union challenged Stalin regarding his use of the CHEKA to rein in dissidents, and upon his return to Spain convinced the PSOE to reject affiliation with the 5th to 7th Comintern. From the Comintern’s point of view the increasingly powerful, if fragmented, left and the weak right were an optimum situation. Their goal was to use a veil of legitimate democratic institutions to outlaw the right, converting the state into the Soviet vision of a “people’s republic” with total leftist domination, a goal repeatedly voiced in Comintern instructions and in the public statements of the Communist Party of Spain. The left and Basque or Catalan nationalist conservatives had many conflicting ideas. The Cortes (Spanish Parliament) consisted of 16 parties in 1931. An attempt by the communists to seize control resisted by anarchists resulted in the massacre of hundreds of rebels and civil war between communists and anarchists in Catalonia.

The actions of the Republican government slowly coagulated the different people on the right.

The Nationals included the majority of the Catholic clergy and of practicing Catholics (outside of the Basque region), important elements of the army, most of the large landowners, and many businessmen. The Republicans included most urban workers, most peasants, and much of the educated middle class, especially those who were not entrepreneurs.

Republicans
Republicans (also known as Spanish loyalists) received weapons and volunteers from the Soviet Union, Mexico, the international Marxists movement and the International Brigades. The Republicans ranged from centrists who supported a moderately capitalist liberal democracy to revolutionary anarchists; their power base was primarily secular and urban, but also included landless peasants, and it was particularly strong in industrial regions like Asturias and Catalonia. This faction was called variously the “loyalists” by its supporters; the “Republicans”, “the Popular Front” or “the Government” by all parties; and “the reds” by its enemies. Regarding the term “loyalist”, Historian Stanley Payne notes: “the adjective “loyalist” is somewhat misleading, for there was no attempt to remain loyal to the constitutional Republican regime. If that had been the scrupulous policy of the left, there would have been no revolt and civil war in the first place.”

The conservative, strongly Catholic Basque country, along with Galicia and the more left-leaning Catalonia, sought autonomy or even independence from the central government of Madrid. This option was left open by the Republican government. All these forces were gathered under the People’s Republican Army (Ejército Popular Republicano, or EPR).

Nationalists
The Nationalists (also called “insurgents”, “rebels” or by opponents “Francoists” or overinclusively as “Fascists”) fearing national fragmentation, opposed the separatist movements, and were chiefly defined by their anti-communism, which galvanized diverse or opposed movements like falangists or monarchists. Their leaders had a generally wealthier, more conservative, monarchist, landowning background, and (with the exception of the Carlists) favoured the centralization of state power.

One of the Nationalists’ principal stated motives was to confront the anti-clericalism of the Republican regime and to defend the Church, which had been the target of attacks, and which many on the Republican side blamed for the ills of the country. Even before the war, in the Asturias uprising of 1934 religious buildings were burnt and at least 100 clergy, religious, and police were killed, but the president and the radicals prevented the implementation of any serious sanctions against the revolutionaries. According to Payne:

More than 1,000 were killed, the majority revolutionaries, and there were atrocities on both sides. The revolutionaries shot nearly 100 people in cold blood, most of them policemen and priests, and an almost equal number of rebels–possibly even more–were executed out of hand by the troops that suppressed the revolt.

Articles 24 and 26 of the Constitution of the Republic had banned the Jesuits, which deeply offended many within the conservatives. The revolution in the republican zone at the outset of the war, killing 7,000 clergy and thousands of lay people, drove many Catholics, left then with little alternative, to the Nationalists. Franco’s first proclamation from Tenerife however, as historian Hilari Raguer has observed, “failed to invoke a religious motive behind the Uprising. It denounces the disorder, the revolutionary atmosphere, the violation of the constitution and the new emergency regulations. Leaving aside the volunteers from Navarra, the first rebel on record as having publicly declared a religious motivation was His Imperial Highness Muley Hassan ben El Mehdi, the Jalifa of the Spanish zone of the Moroccan protectorate. When blessing the first Moors to leave for the peninsula, he declared a Holy War against those evil Spaniards who did not display the sign of God on their banners.”

Other factions
Catalan and Basque nationalists were not univocal. Left-wing Catalan nationalists were on the Republican side. Conservative Catalan nationalists were far less vocal supporting the Republican government due to the anti-clericalism and confiscations occurring in some areas controlled by the latter (some conservative Catalan nationalists like Francesc Cambó actually funded the Nationalist side). Basque nationalists, heralded by the conservative Basque nationalist party, were mildly supportive of the Republican government, even though Basque nationalists in Álava and Navarre sided with the uprising for the same reasons influencing Catalan conservative nationalists. Notwithstanding the religious matters, the Basque nationalists, who nearly all sided with the Republic, were, for the most part, practicing Catholics.

Foreign involvement
The Spanish Civil War had large numbers of non-Spanish citizens participating in combat and advisory positions. Foreign governments contributed large amounts of financial assistance and military aid to forces led by Franco. Forces fighting on behalf of the Republicans also received limited aid, but support was seriously hampered by the arms embargo declared by France and the UK. These embargoes were never very effective however, and France especially was accused of allowing large shipments through to the Republicans (but the accusations often came from Italy, itself heavily involved for the Nationalists). The clandestine actions of the various European powers were at the time considered to be risking another ‘Great War’.

The League of Nations’ reaction to the war was mostly neutral and insufficient to contain the massive importation of arms and other war resources by the fighting factions. Although a Non-Intervention Committee was created, its policies were largely ineffective. Its directives were dismantled due to the policies of appeasement of both European democratic and non-democratic powers of the late 1930s: the official Spanish government of Juan Negrín was gradually abandoned within the organization during this period.

Support for Nationalists
Despite the Irish government’s prohibition against participating in the war, around 700 Irishmen, followers of Eoin O’Duffy known as the “Irish Brigade”, went to Spain to fight on Franco’s side. The Nationalists received weapons and logistical support from Portugal. In addition approximately 8,000 Portuguese volunteers, known as Viriatos after an aborted national legion that failed to get off the ground in the early months of the war, fought in Franco’s forces. Romanian volunteers were led by Ion I Moţa, deputy-leader of the Legion of the Archangel Michael (or Iron Guard), whose group of seven Legionaries visited Spain in December 1936 to ally their movement to the Nationalists. Moţa was killed in action at Majadahonda on January 13, 1937.

Germany
Francisco Franco asked Adolf Hitler from Nazi Germany and Benito Mussolini from Fascist Italy to aid the Nationalists. Hitler agreed and ordered three major military operations in Spain during the Spanish Civil War. He authorized Operation Feuerzauber (“Fire Magic”) in late July 1936. He mobilized 20 three-motor Junkers Ju 52 planes with six escort fighters, 85 Germans on the SS Usaramo ship to work on the planes, and transferred German troops stationed in Morocco to Spain. A few months later in late September, Hitler again mobilized men and materials to aid Franco for Operation Otto. He sent 24 more Panzer I light tanks, a flak, and some radio equipment. German commander Major Alexander von Scheele also converted the Junkers 52s to bombers. By October, there were an estimated 600–800 German soldiers in Spain. Hitler’s largest and last move was the Condor Legion (Legion Condor). Initiated in November 1936, he sent an additional 3,500 troops into combat and supplied the Spanish Nationalists with 92 new planes. Hitler kept the Condor Legion in Spain until the end of the war in May 1939. At its zenith, the German force numbered about 12,000 men, and as many as 19,000 Germans fought in Spain. In total Nazi Germany provided Nationalists with 600 planes, 200 tanks, and 1,000 artillery pieces. Scholars such as Robert Whealey have published books on interactions between Nazis and Spain during this time.

Italy
After Franco’s request and in response to Adolf Hitler’s encouragement, Benito Mussolini joined the war, partly because he did not want to be outdone by Hitler. While Mussolini sent more ground troops than Hitler, he initially supplied fewer materials. At the beginning of war in September 1936, Mussolini had only supplied 68 aircraft and several hundred small arms to the Nationalists. However, the Royal Italian Navy (Regia Marina Italiana) played a major role in the Mediterranean blockade and ultimately Italy supplied machine guns, artillery, aircraft, tankettes, the “Legionary Air Force” (Aviazione Legionaria), and the “Corps of Volunteer Troops” (Corpo Truppe Volontarie, or CTV). The Italian CTV reached a high of about 50,000 men and, by rotation, more than 75,000 Italians were to fight for the Nationalists in Spain. In total fascist Italy provided Nationalists with 660 planes, 150 tanks and 1,000 artillery pieces.

Portugal
Salazar’s Estado Novo played a most important role in supplying Franco’s forces with ammunition and many other logistical resources. Despite its discreet direct military involvement — restrained to a somewhat “semi-official” endorsement, by its authoritarian regime, of an 8,000–12,000-strong volunteer force, the so-called “Viriatos” — for the whole duration of the conflict, Portugal was instrumental in providing the Nationalists with a vital logistical organization and by reassuring Franco and his allies that no interference whatsoever would hinder the supply traffic directed to the Nationalists, crossing the borders of the two Iberian countries — the Nationalists used to refer to Lisbon as “the port of Castile”.

Support for Republicans
International Brigades
Many non-Spanish people, often affiliated with radical, communist or socialist parties or groups, joined the International Brigades, believing that the Spanish Republic was the front line of the war against fascism. The troops of the International Brigades represented the largest foreign contingent of those fighting for the Republicans. Roughly 30,000 foreign nationals from up to 53 nations fought in the brigades. Most of them were communists or trade unionists, and while organised by communists guided or controlled by Moscow, they were almost all individual volunteers.

Likely more than 1,000 volunteers came from each of France, Italy, Germany, Poland, USSR, USA, UK, Belgium, Czechoslovakia, Ireland, Yugoslavia, Hungary and Canada. The Thälmann Battalion was a group of German, Swiss, Austrian and Scandinavian volunteers who distinguished themselves during the Siege of Madrid. The American volunteers fought in units such as the Abraham Lincoln Brigade and Canadians in the Mackenzie-Papineau Battalion.

Over five hundred Romanians fought on the Republican side, including Romanian Communist Party members Petre Borilă and Valter Roman.

Some Chinese joined the international brigades. At the end of the war, the majority returned to China, while some went to prison, others went to refugee camps in southern France, and a handful remained in Spain, including about ten who married Spanish women.

Soviet Union
The Soviet Union primarily provided material assistance to the Republican forces. In total the USSR provided Spain with 806 planes, 362 tanks, and 1,555 artillery pieces. The Soviet Union ignored the League of Nations embargo and sold arms to the Republic when few other nations would do so; thus it was the Republic’s only important source of major weapons. Stalin had signed the Non-Intervention Agreement but decided to break the pact. However, unlike Hitler and Mussolini who openly violated the pact, Stalin tried to do so secretly. He created a section X of the Soviet Union military to head the operation, coined Operation X. However, while a new branch of the military was created especially for Spain, most of the weapons and artillery sent to Spain were antiques. Stalin did not want the arms to be traceable to the Soviet Union, so most were taken from museums from around the country. He also used weapons captured from past conflicts. However, modern weapons such as BT-5 tanks and I-16 fighter aircraft were also supplied to Spain.

Many of the Soviet’s deliveries were lost or smaller than Stalin had ordered. He only gave short notice, which meant many weapons were lost in the delivery process. Lastly, when the ships did leave with supplies for the Republicans, the journey was extremely slow. Stalin ordered the builders to include false decks in the original design of the boat. Then, once the ship left shore it was required to change its flag and change the color of parts of the ship to minimize capture by the Nationalists. However in 1938, Stalin withdrew his troops and tanks as government ranks floundered.

The Republic had to pay for Soviet arms with the official gold reserves of the Bank of Spain, in an affair that would become a frequent subject of Francoist propaganda afterward (see Moscow Gold). The cost to the Republic of Soviet arms was more than US $500 million, two-thirds of the gold reserves that Spain had at the beginning of the war.

The Soviet Union also sent a number of military advisers to Spain (2,000-3,000). While Soviet troops amounted to no more than 700 men, Soviet “volunteers” often operated Soviet-made Republican tanks and aircraft. In addition, the Soviet Union directed Communist parties around the world to organize and recruit the International Brigades.

Another significant Soviet involvement was the pervasive activities of the NKVD all along the Republican rearguard. Communist figures like Vittorio Vidali (“Comandante Contreras”), Iosif Grigulevich and, above all, Alexander Orlov led those not-so-secret operations, that included murders like those of Andreu Nin and José Robles.

Mexico
Unlike the United States and major Latin American governments such as the ABC Powers and Peru, the Mexican government supported the Republicans. Mexico refused to follow the French-British non-intervention proposals. Mexico furnished $2,000,000 in aid and provided some material assistance, which included 20,000 rifles, 28 million cartridges, 8 artillery pieces and small number of American-made aircraft such as the Bellanca CH-300 and Spartan Zeus that served in the Mexican Air Force.

However, Mexico’s most important contributions to the Spanish Republic were diplomatic and to provide sanctuary for Republican refugees including many Spanish intellectuals and orphaned children from Republican families.

Course of the war
1936
Coup leader Sanjurjo was killed in a plane crash on 20 July, leaving an effective command split between Mola in the North and Franco in the South. On 21 July, the fifth day of the rebellion, the Nationalists captured the main Spanish naval base at Ferrol in northwestern Spain. A rebel force under Colonel Beorlegui Canet, sent by General Emilio Mola, undertook the Campaign of Guipúzcoa from July to September. The capture of Guipúzcoa isolated the Republican provinces in the north. On 5 September, after heavy fighting the force took Irún, closing the French border to the Republicans. On 13 September, the Basques surrendered San Sebastián to the Nationalists, who then advanced toward their capital, Bilbao. The Republican militias on the border of Vizcaya halted these forces at the end of September.

Franco was chosen overall Nationalist commander at a meeting of ranking generals at Salamanca on 21 September. Franco won another victory on 27 September when they relieved the Alcázar at Toledo. A Nationalist garrison under Colonel Moscardo had held the Alcázar in the center of the city since the beginning of the rebellion, resisting thousands of Republican troops who completely surrounded the isolated building. The Republic’s inability to take the Alcázar was a serious blow to its prestige in view of its overwhelming numerical superiority in the area. Two days after relieving the siege, Franco proclaimed himself Generalísimo and Caudillo (“chieftain”), while forcibly unifying the various and diverse Falangist, Royalist and other elements within the Nationalist cause.

In October, the Francoist troops launched a major offensive toward Madrid, reaching it in early November and launching a major assault on the city on 8 November. The Republican government was forced to shift from Madrid to Valencia, out of the combat zone, on 6 November. However, the Nationalists’ attack on the capital was repulsed in fierce fighting between 8 November and 23 November. A contributory factor in the successful Republican defense was the arrival of the International Brigades, though only around 3,000 of them participated in the battle. Having failed to take the capital, Franco bombarded it from the air and, in the following two years, mounted several offensives to try to encircle Madrid.

1937
With his ranks swelled by Italian troops and Spanish colonial soldiers from Morocco, Franco made another attempt to capture Madrid in January and February 1937, but again failed.

On 21 February the League of Nations Non-Intervention Committee ban on foreign national “volunteers” went into effect. The large city of Málaga was taken on 8 February. On 7 March, the German Condor Legion equipped with Heinkel He 51 biplanes arrived in Spain; on 26 April the Legion bombed the town of Guernica, killing hundreds. Two days later, Franco’s army overran the town.

After the fall of Guernica, the Republican government began to fight back with increasing effectiveness. In July, they made a move to recapture Segovia, forcing Franco to pull troops away from the Madrid front to halt their advance. Mola, Franco’s second-in-command, was killed on 3 June, and in early July, despite the fall of Bilbao in June, the government launched a strong counter-offensive in the Madrid area, which the Nationalists repulsed with difficulty. The clash was called “Battle of Brunete” after a town in the province of Madrid.

Franco invaded Aragón in August and then took the city of Santander. With the surrender of the Republican army in the Basque territory and after two months of bitter fighting in Asturias (Gijón finally fell in late October) Franco had effectively won in the north. At the end of November, with Franco’s troops closing in on Valencia, the government had to move again, this time to Barcelona.

1938
The Battle of Teruel was an important confrontation. The city belonged to the Nationalists at the beginning of the battle, but the Republicans conquered it in January. The Francoist troops launched an offensive and recovered the city by 22 February, but in order to do so Franco relied heavily on German and Italian air support and repaid them with extensive mining rights.

On 7 March, the Nationalists launched the Aragon Offensive. By 14 April, they had pushed through to the Mediterranean, cutting the Republican-held portion of Spain in two. The Republican government tried to sue for peace in May, but Franco demanded unconditional surrender; the war raged on. In July, the Nationalist army pressed southward from Teruel and south along the coast toward the capital of the Republic at Valencia but was halted in heavy fighting along the XYZ Line, a system of fortifications defending Valencia.

The Republican government then launched an all-out campaign to reconnect their territory in the Battle of the Ebro, from 24 July until 26 November. The campaign was unsuccessful, and was undermined by the Franco-British appeasement of Hitler in Munich with the concession of Czechoslovakia. This effectively destroyed Republican morale by ending hope of an anti-fascist alliance with the Western powers. The retreat from the Ebro all but determined the final outcome of the war. Eight days before the new year, Franco threw massive forces into an invasion of Catalonia.

1939
Franco’s troops conquered Catalonia in a whirlwind campaign during the first two months of 1939. Tarragona fell on 14 January, followed by Barcelona on 26 January and Girona on 5 February. Five days after the fall of Girona, the last resistance in Catalonia was broken.

On 27 February, the United Kingdom and France recognized the Franco regime.

Only Madrid and a few other strongholds remained for the Republican forces. Then, on 28 March, with the help of pro-Franco forces inside the city, Madrid fell to the Nationalists. The next day, Valencia, which had held out under their guns for close to two years, also surrendered. Franco proclaimed victory in a radio speech aired on 1 April, when the last of the Republican forces surrendered.

After the end of the War, there were harsh reprisals against Franco’s former enemies; thousands of Republicans were imprisoned and at least 30,000 executed. Other calculations of these deaths range from 50,000 to 200,000. Many others were put to forced labour, building railways, drying out swamps, digging canals, etc.

Hundreds of thousands of Republicans fled abroad, some 500,000 to France. Refugees were confined in internment camps of the French Third Republic, such as Camp Gurs or Camp Vernet, where 12,000 Republicans were housed in squalid conditions. Of the 17,000 refugees housed in Gurs, the farmers and ordinary people who could not find relations in France were encouraged by the Third Republic, in agreement with the Francoist government, to return to Spain. The great majority did so and were turned over to the Francoist authorities in Irún. From there they were transferred to the Miranda de Ebro camp for “purification” according to the Law of Political Responsibilities. After the proclamation by Marshal Philippe Pétain of the Vichy regime, the refugees became political prisoners, and the French police attempted to round up those who had been liberated from the camp. Along with other “undesirables”, they were sent to the Drancy internment camp before being deported to Nazi Germany. About 5,000 Spaniards thus died in Mauthausen concentration camp.

After the official end of the war, guerrilla war was waged on an irregular basis well into the 1950s, being gradually reduced by military defeats and scant support from the exhausted population. In 1944, a group of republican veterans, who also fought in the French resistance against the Nazis, invaded the Val d’Aran in northwest Catalonia, but were defeated after ten days.

Evacuation of children
As war proceeded on the Northern front, the Republican authorities arranged the evacuation of children. These Spanish War children were shipped to Britain, Belgium, the Soviet Union, other European countries and Mexico. These children were referred to as ‘Basque refugees,’ even though they were a diverse group. Those in Western European countries were able to return to their families after the war, but those in the Soviet Union, from Communist families, were forbidden to return – by Stalin and by Franco. The first opportunity for most of them to do so came in 1956, three years after Stalin’s death. They lived in Soviet orphanages and were regularly transferred from one orphanage to another according to the progress of the Second World War. Thus they experienced the War and its effects on the Soviet Union at first hand.

The Nationalist side also arranged evacuations of children, women and elderly from war zones. Refugee camps for those civilians evacuated by the Nationalists were set up in Portugal, Italy, Germany, the Netherlands and Belgium.

Stoneham Camp in England
One example of a large refugee camp was located in Great Britain. Over 4,000 children arrived at the Southhampton Docks on 23rd of May 1937. They traveled to Britain on the steamship Habana. The ship had been equipped to accommodate 800 passengers, but this voyage consisted of 3840 children, 80 teachers, 120 assistants, 15 Catholic priests, and 2 doctors. These refugees were moved to a camp at North Stoneham that been constructed only two days prior to their arrival. Building had begun two weeks before, but the estimated numbers had been only 2,000. The camps were overcrowded with dozens of children staying in the same tent. Sanitation was also a problem in the beginning as the children had been living through war and their hygienic habits had been disrupted by their turbulent lives. Even with the cramped conditions illness was not a large problem within the camp.

The plan was to move the refugees out of the camps and disperse them into villages throughout Britain. By September all of the children were actually moved into these villages, mostly into residential homes. A few were taken in my The Salvation Army, the Catholic church, and other volunteers. After the war was over the displaced children were allowed to return to Spain. Those age 16 and above were allowed to decide whether or not they wanted to leave the country. Some were forced to stay because their parents had been killed or imprisoned, others stayed by choice.

Atrocities
At least 50,000 people were executed during the war. In his updated history of the Spanish Civil War, Antony Beevor writes, “Franco’s ensuing ‘white terror’ claimed 200,000 lives. The ‘red terror’ had already killed 38,000.” Julius Ruiz concludes that “although the figures remain disputed, a minimum of 37,843 executions were carried out in the Republican zone with a maximum of 150,000 executions (including 50,000 after the war) in Nationalist Spain.” César Vidal puts the number of Republican victims at 110,965. In 2008 a Spanish judge, Baltasar Garzón, opened an investigation into the executions and disappearances of 114,266 people between 17 July 1936 and December 1951 (he has since been indicted for violating a 1977 amnesty by these actions). Among the executions investigated was that of the poet and dramatist Federico García Lorca.

In the early days of the war, executions of people who were caught on the “wrong” side of the lines became widespread in conquered areas. The outbreak of the war provided an excuse for settling accounts and resolving longstanding feuds. In these paseos (“strolls”), as the executions were called, the victims were taken from their refuges or jails to be shot outside of town. The corpses were abandoned or interred in graves dug by the victims themselves. Local police just noted the appearance of the corpses.

Nationalists
The atrocities of the Nationalists, frequently ordered by authorities in order to eradicate any trace of leftism in Spain, were common. According to historian Paul Preston, the minimum number of those executed by the rebels is 130,000, and is likely to be far higher. The violence carried out in the rebel zone was carried out by the military, the “Civil Guard”, the Falange in the name of the regime and legitimized by the Catholic Church.

Many such acts were committed by reactionary groups during the first weeks of the war. This included the execution of school teachers (because the efforts of the Second Spanish Republic to promote laicism and to displace the Church from the education system by closing religious schools were considered by the Nationalists as an attack on the Roman Catholic Church); the massive killings of civilians in the cities they captured; the execution of unwanted individuals (including non-combatants such as trade-unionists and known Republican sympathisers etc.).

Nationalist forces committed massacres in Seville, where some 10,000 people were shot. In Granada, about 8000 people were murdered. After the capture of Almendralejo, about 1000 prisoners were shot, including 100 women. Some 2000 were shot when Badajoz was conquered by Yague. In February 1937, over 4000 were killed after the capture of Malaga. When Bilbao was conquered, some 1000 people were executed. The numbers of people killed as the African columns raped, looted, and murdered their way through Seville and Madrid are particularly difficult to calculate.

Nationalists murdered Catholic clerics. In one particular incident, following the capture of Bilbao, hundreds of people, including 16 priests who had served as chaplains for the Republican forces, were taken to the countryside or to graveyards to be murdered.

Franco’s forces persecuted Protestants. They murdered Protestant ministers. Franco’s forces were determined to remove from Spain the “Protestant heresy”. Pastor Miguel Blanco of Seville was shot as was Pastor Jose Garcia Fernandez of Granada. In Zaragoza, on August 18, the church was attacked by Franco’s forces. They destroyed furniture, burned Bibles and books and stole valuables. Many Protestants were imprisoned and tortured.

The Nationalists also persecuted the Basque people. They were determined to eradicate Basque culture. According to Basque sources, some 22,000 Basques were murdered by Nationalists immediately after the Civil War.

The Nationalist side also conducted aerial bombing of cities in Republican territory, carried out mainly by the Luftwaffe volunteers of the Condor Legion and the Italian air force volunteers of the Corpo Truppe Volontarie (Madrid, Barcelona, Valencia, Guernica, and other cities). The most notorious example of this tactic of terror bombings was the Bombing of Guernica.

Republicans
An estimated 55,000 civilians died in Republican-held territories. The Republican government was anticlerical and supporters attacked and murdered Roman Catholic clergy in reaction to news of the military revolt. In Republican held territories, Roman Catholic churches, convents, monasteries, and cemeteries were desecrated. Through the war, nearly all segments of the Republicans, Basques being a notable exception, took part in semi-organized anti-Roman Catholic, anticlerical killing of 6,832 members of the Catholic clergy and religious orders (including 13 bishops, 4,172 priests, 2,364 monks and friars, and 283 nuns). By the end of the war 20 percent of the nation’s clergy had been killed.

As well as clergy, civilians were executed in Republican areas. Some civilians were executed as suspected fifth columnists. Others died in revenge due to news of the massacres carried out in the Nationalist zone. Air raids committed against Republican cities were another factor. Historian Paul Preston emphasizes that Republican authorities did not order such measures to be taken. As pressure mounted with increasing success of the Nationalists, many civilians were executed by councils and tribunals controlled by competing Communist and Anarchist groups. Some anarchists were executed by Soviet-advised communist functionaries in Catalonia as described by George Orwell’s description of the purges in Barcelona in 1937 in Homage to Catalonia, which followed a period of increasing tension between Competing elements of the Catalan political scene.

Republicans initially reacted to the attempted coup by arresting and executing actual and perceived Nationalists. In the Andalusian town of Ronda, 512 alleged Nationalists were executed in the first month of the war.

Communist Santiago Carrillo Solares has been accused of the killing of Nationalists in the Paracuellos massacre near Paracuellos del Jarama and Torrejón de Ardoz. However, the extent to which (in particular) Carrillo was responsible remains a source of debate. The Pro-Soviet Communists committed numerous atrocities against fellow Republicans, including other Marxists: André Marty, known as the Butcher of Albacete, was responsible for the deaths of some 500 members of the International Brigades. Andreu Nin, leader of the POUM (Workers’ Party of Marxist Unification), and many prominent POUM members were murdered by the Communists.

Social revolution
In the anarchist-controlled areas, Aragón and Catalonia, in addition to the temporary military success, there was a vast social revolution in which the workers and peasants collectivised land and industry, and set up councils parallel to the paralyzed Republican government. This revolution was opposed by both the Soviet-supported communists, who ultimately took their orders from Stalin’s politburo (which feared a loss of control), and the Social Democratic Republicans (who worried about the loss of civil property rights). The agrarian collectives had considerable success despite opposition and lack of resources.

As the war progressed, the government and the communists were able to leverage their access to Soviet arms to restore government control over the war effort, through both diplomacy and force. Anarchists and the Workers’ Party of Marxist Unification (Partido Obrero de Unificación Marxista, or POUM) were integrated into the regular army, albeit with resistance; the POUM was outlawed and falsely denounced as an instrument of the fascists. In the May Days of 1937, many thousands of anarchist and communist republican soldiers fought for control of strategic points in Barcelona.

The pre-war Falange was a small party of some 30–40,000 members. It also called for a social revolution that would have seen Spanish society transformed by National Syndicalism. Following the execution of its leader, José Antonio Primo de Rivera, by the Republicans, the party swelled in size to over 400,000. The leadership of the Falange suffered 60% casualties in the early days of the civil war and the party was transformed by new members and rising new leaders, called camisas nuevas (“new shirts”), who were less interested in the revolutionary aspects of National Syndicalism. Subsequently, Franco united all rightist parties into the ironically named Falange Española Tradicionalista de las Juntas de Ofensiva Nacional-Sindicalista (FET y de las JONS), or the Traditionalist Spanish Falange of the Unions of the National-Syndicalist Offensive.

The 1930s also saw Spain become a focus for pacifist organizations including the Fellowship of Reconciliation, the War Resisters League and the War Resisters’ International. Many people including, as they are now called, the ‘insumisos’ (‘defiant ones’, conscientious objectors) argued and worked for non-violent strategies. Prominent Spanish pacifists such as Amparo Poch y Gascón and José Brocca supported the Republicans. Brocca argued that Spanish pacifists had no alternative but to make a stand against fascism. He put this stand into practice by various means including organizing agricultural workers to maintain food supplies and through humanitarian work with war refugees.
