The International Brigades ( es|Brigadas Internacionales) were military units set up by the Communist International
to assist the Popular Front
government of the Second Spanish Republic
during the Spanish Civil War
. The organization existed for two years, from 1936 until 1938. It is estimated that during the entire war, between 40,000 and 59,000 members served in the International Brigades, including 15,000 who died in combat.
[Thomas (2003), pp. 941–945; Beevor (2006), p. 157.]
The headquarters of the brigade was located at the Gran Hotel, Albacete
, Castilla-La Mancha
. They participated in the battles of Madrid
and the Ebro
. Most of these ended in defeat. For the last year of its existence, the International Brigades were integrated into the Spanish Republican Army
as part of the Spanish Foreign Legion
. The organisation was dissolved on 23 September 1938 by Spanish Prime Minister, Juan Negrín
, in a vain attempt to get more support from the liberal democracies on the Non-Intervention Committee
The International Brigades was strongly supported by the Comintern
and represented the Soviet Union
's commitment to assisting the Spanish Republic (with arms, logistics, military advisers and the NKVD
), just as Fascist Italy
, Fascist Portugal
and Nazi Germany
were assisting the opposing Nationalist insurgency
[Thomas (2003), pp. 941–945.]
The largest number of volunteers came from France
(where the French Communist Party
had many members) and communist
exiles from Italy and Germany. Many Jews
were part of the brigades, being particularly numerous within the volunteers coming from the United States, Poland, France, England and Argentina.
Republican volunteers who were opposed to Stalinism
did not join the Brigades but instead enlisted in the separate Popular Front
, the POUM
(formed from Trotskyist
and other anti-Stalinist
groups, which did not separate Spaniards and foreign volunteers -such as George Orwell
[Homage to Catalonia. Author: Orwell, George.Publisher: Penguin Group. Date: Re-print, 2000. Work: Auto-biographical account of the Author's participation in the Spanish Civil War. ]
groups such as the Durruti Column
, the IWA
and the CNT
Formation and recruitment
Using foreign communist parties
to recruit volunteers for Spain was first proposed in the Soviet Union in September 1936—apparently at the suggestion of Maurice Thorez
—by Willi Münzenberg
, chief of Comintern
propaganda for Western Europe. As a security measure, non-communist volunteers would first be interviewed by an NKVD
By the end of September, the Italian and French Communist Parties had decided to set up a column. Luigi Longo
, ex-leader of the Italian Communist Youth
, was charged to make the necessary arrangements with the Spanish government. The Soviet Ministry of Defense
also helped, since they had an experience of dealing with corps of international volunteers during the Russian Civil War
. The idea was initially opposed by Largo Caballero
, but after the first setbacks of the war, he changed his mind and finally agreed to the operation on 22 October. However, the Soviet Union did not withdraw from the Non-Intervention Committee
, probably to avoid diplomatic conflict with France and the United Kingdom.
The main recruitment center was in Paris, under the supervision of Soviet colonel Karol "Walter" Świerczewski
. On 17 October 1936, an open letter by Joseph Stalin
to José Díaz
was published in ''Mundo Obrero'', arguing that victory for the Spanish second republic was a matter not only for Spaniards but also for the whole of "progressive humanity"; in short order, communist activists joined with moderate socialist and liberal groups to form anti-fascist "popular front" militias in several countries, most of them under the control of or influenced by the Comintern
Entry to Spain was arranged for volunteers, for instance, a Yugoslav, Josip Broz, who would become famous as Marshal Josip Broz Tito
, was in Paris to provide assistance, money, and passports for volunteers from Eastern Europe
. Volunteers were sent by train or ship from France to Spain, and sent to the base at Albacete
. Many of them also went by themselves to Spain. The volunteers were under no contract, nor defined engagement period, which would later prove a problem.
Also, many Italians, Germans, and people from other countries joined the movement, with the idea that combat in Spain was the first step to restore democracy
or advance a revolutionary cause in their own country. There were also many unemployed workers (especially from France), and adventurers. Finally, some 500 communists who had been exiled to Russia were sent to Spain (among them, experienced military leaders from the First World War like "Kléber" Stern
, "Gomez" Zaisser
, "Lukacs" Zalka
and "Gal" Galicz
, who would prove invaluable in combat).
The operation was met with enthusiasm by communists, but by anarchist
s with skepticism, at best. At first, the anarchists, who controlled the borders with France, were told to refuse communist volunteers, but reluctantly allowed their passage after protests. A group of 500 volunteers (mainly French, with a few exiled Poles and Germans) arrived in Albacete on 14 October 1936. They were met by international volunteers who had already been fighting in Spain: Germans from the Thälmann Battalion
, Italians from the Centuria Gastone Sozzi
and French from the Commune de Paris Battalion
. Among them was British poet John Cornford
. Men were sorted according to their experience and origin and dispatched to units.:)
On 30 May 1937, the Spanish liner ''Ciudad de Barcelona
'', carrying 200–250 volunteers from Marseille
to Spain, was torpedoed by a Nationalist submarine off the coast of Malgrat de Mar
. The ship sunk and up to 65 volunteers are estimated to have drowned.
Albacete soon became the International Brigades headquarters and its main depot. It was run by a ''troika'' of Comintern
heavyweights: André Marty
was commander; Luigi Longo
(''Gallo'') was Inspector-General; and Giuseppe Di Vittorio
(''Nicoletti'') was chief political commissar.
The French Communist Party
provided uniforms for the Brigades. They were organized into mixed brigade
s, the basic military unit of the Republican People's Army
. Discipline was severe. For several weeks, the Brigades were locked in their base while their strict military training was underway.
First engagements: Siege of Madrid
The battle of Madrid
was a major success for the Republic, and staved off the prospect of a rapid defeat at the hands of Francisco Franco
's forces. The role of the International Brigades in this victory was generally recognized but was exaggerated by Comintern
propaganda so that the outside world heard only of their victories and not those of Spanish units. So successful was such propaganda that the British Ambassador, Sir Henry Chilton, declared that there were no Spaniards in the army which had defended Madrid. The International Brigade forces that fought in Madrid arrived after another successful Republican fighting. Of the 40,000 Republican troops in the city, the foreign troops numbered less than 3,000.
Even though the International Brigades did not win the battle by themselves, nor significantly change the situation, they certainly did provide an example by their determined fighting and improved the morale of the population by demonstrating the concern of other nations in the fight. Many of the older members of the International Brigades provided valuable combat experience, having fought during the First World War
(Spain remained neutral in 1914–1918) and the Irish War of Independence
(some had fought in the British Army
while others had fought in the Irish Republican Army
One of the strategic positions in Madrid was the Casa de Campo
. There the Nationalist troops were Moroccans
, commanded by General José Enrique Varela
. They were stopped by III and IV Brigades of the Spanish Republican Army
On 9 November 1936, the XI International Brigade
– comprising 1,900 men from the Edgar André Battalion
, the Commune de Paris Battalion
and the Dabrowski Battalion
, together with a British machine-gun company — took up position at the Casa de Campo. In the evening, its commander, General Kléber
, launched an assault on the Nationalist positions. This lasted for the whole night and part of the next morning. At the end of the fight, the Nationalist troops had been forced to retreat, abandoning all hopes of a direct assault on Madrid by Casa de Campo, while the XIth Brigade had lost a third of its personnel.
On 13 November, the 1,550-man strong XII International Brigade
, made up of the Thälmann Battalion
, the Garibaldi Battalion
and the André Marty Battalion
, deployed. Commanded by General "Lukacs"
, they assaulted Nationalist positions on the high ground of Cerro de Los Angeles
. As a result of language and communication problems, command issues, lack of rest, poor coordination with armored units, and insufficient artillery support, the attack failed.
On 19 November, the anarchist militia
s were forced to retreat, and Nationalist troops — Moroccans and Spanish Foreign Legion
naires, covered by the Nazi Condor Legion
— captured a foothold in the University City
. The 11th Brigade was sent to drive the Nationalists out of the University City. The battle was extremely bloody, a mix of artillery
and aerial bombardment
, with bayonet
fights, room by room. Anarchist leader Buenaventura Durruti
was shot there on 19 November 1936 and died the next day. The battle in the University went on until three-quarters of the University City was under Nationalist control. Both sides then started setting up trenches and fortifications. It was then clear that any assault from either side would be far too costly; the Nationalist leaders had to renounce the idea of a direct assault on Madrid, and prepare for a siege
of the capital.
On 13 December 1936, 18,000 nationalist troops attempted an attack to close the encirclement of Madrid at Guadarrama
— an engagement known as the Battle of the Corunna Road
. The Republicans sent in a Soviet armored unit, under General Dmitry Pavlov
, and both XI and XII International Brigades. Violent combat followed, and they stopped the Nationalist advance.
An attack was then launched by the Republic on the Córdoba
front. The battle ended in a form of stalemate; a communique was issued, saying: "During the day the advance continued without the loss of any territory." Poets Ralph Winston Fox
and John Cornford
were killed. Eventually, the Nationalists advanced, taking the hydroelectric
station at El Campo
. André Marty
accused the commander of the Marseillaise Battalion
, Gaston Delasalle
, of espionage
and had him executed. (It is doubtful that Delasalle would have been a spy for Francisco Franco; he was denounced by his second-in-command, André Heussler
, who was subsequently executed for treason during World War II by the French Resistance
Further Nationalist attempts after Christmas to encircle Madrid met with failure, but not without extremely violent combat. On 6 January 1937, the Thälmann Battalion arrived at Las Rozas
, and held its positions until it was destroyed as a fighting force. On 9 January, only 10 km had been lost to the Nationalists, when the XIII International Brigade
and XIV International Brigade
and the 1st British Company, arrived in Madrid. Violent Republican assaults were launched in an attempt to retake the land, with little success. On 15 January, trenches and fortifications were built by both sides, resulting in a stalemate.
The Nationalists did not take Madrid until the very end of the war, in March 1939, when they marched in unopposed. There were some pockets of resistance during the subsequent months.
Battle of Jarama
On 6 February 1937, following the fall of Málaga
, the nationalists launched an attack on the Madrid
road, south of Madrid. The Nationalists quickly advanced on the little town of Ciempozuelos
, held by the XV International Brigade
. was composed of the British Battalion
), the Dimitrov Battalion
nationalities), the Sixth February Battalion
and French), the Canadian Mackenzie-Papineau Battalion
and the Abraham Lincoln Brigade
. An independent 80-men-strong (mainly) Irish unit, known afterward as the Connolly Column
, also fought. Battalions were rarely composed entirely of one nationality, rather they were, for the most part, a mix of many.
On 11 February 1937, a Nationalist brigade launched a surprise attack
on the André Marty Battalion
(XIV International Brigade
), killing its sentries silently and crossing the Jarama
. The Garibaldi Battalion stopped the advance with heavy fire. At another point, the same tactic allowed the Nationalists to move their troops across the river. On 12 February, the British Battalion, XV International Brigade
took the brunt of the attack, remaining under heavy fire for seven hours. The position became known as "Suicide Hill". At the end of the day, only 225 of the 600 members of the British battalion remained. One company
was captured by ruse, when Nationalists advanced among their ranks singing ''The Internationale
On 17 February, the Republican Army counter-attacked. On 23 and 27 February, the International Brigades were engaged, but with little success. The Lincoln Battalion was put under great pressure, with no artillery support. It suffered 120 killed and 175 wounded. Amongst the dead was the Irish poet Charles Donnelly
and Leo Greene.
There were heavy casualties on both sides, and although "both claimed victory ... both suffered defeats". The battle resulted in a stalemate, with both sides digging in and creating elaborate trench systems. On 22 February 1937, the League of Nations Non-Intervention Committee
ban on foreign volunteers went into effect.
Battle of Guadalajara
After the failed assault on the Jarama, the Nationalists attempted another assault on Madrid, this time from the northeast. The objective was the town of Guadalajara
, 50 km from Madrid. The whole Italian expeditionary corps — 35,000 men, with 80 battle tanks and 200 field artillery — was deployed, as Benito Mussolini
wanted the victory to be credited to Italy. On 9 March 1937, the Italians made a breach in the Republican lines but did not properly exploit the advance. However, the rest of the Nationalist army was advancing, and the situation appeared critical for the Republicans. A formation drawn from the best available units of the Republican army, including the XI
and XII International Brigade
s, was quickly assembled.
At dawn on 10 March, the Nationalists closed in, and by noon, the Garibaldi Battalion counterattacked. Some confusion arose from the fact that the sides were not aware of each other's movements, and that both sides spoke Italian; this resulted in scouts from both sides exchanging information without realizing they were enemies. The Republican lines advanced and made contact with XI International Brigade. Nationalist tanks were shot at and infantry patrols came into action.
On 11 March, the Nationalist army broke the front of the Republican army. The Thälmann Battalion
suffered heavy losses, but succeeded in holding the Trijueque
road. The Garibaldi also held its positions. On 12 March, Republican planes and tanks attacked. The Thälmann Battalion attacked Trijuete in a bayonet charge and re-took the town, capturing numerous prisoners.
The International Brigades also saw combat in the Battle of Teruel
in January 1938. The 35th International Division
suffered heavily in this battle from aerial bombardment as well as shortages of food, winter clothing, and ammunition. The XIV International Brigade
fought in the Battle of Ebro
in July 1938, the last Republican offensive of the war.
Although exact figures are not available, an estimated 5,857 to 25,229 members of the International Brigades died in Spain, of an estimated 23,670 to 59,380 who served, with estimated death rates of 16.7% to 29.2%. These high casualty rates are blamed on lack of training, poor leadership and use as shock troops
In October 1938, at the height of the Battle of the Ebro
, the Non-Intervention Committee
demanded the withdrawal of the International Brigades. The Republican government of Juan Negrín
announced the decision in the League of Nations
on 21 September 1938. The disbandment was part of an ill-advised effort to get the Nationalists' foreign backers to withdraw their troops and to persuade the Western democracies such as France and Britain to end their arms embargo
on the Republic.
By this time there were about an estimated 10,000 foreign volunteers still serving in Spain for the Republican side, and about 50,000 foreign conscripts for the Nationalists (excluding another 30,000 Moroccans). Perhaps half of the International Brigadistas were exiles or refugees from Nazi Germany, Fascist Italy or other countries, such as Hungary, which had authoritarian right-wing governments at the time. These men could not safely return home and some were instead given honorary Spanish citizenship and integrated into Spanish units of the Popular Army. The remainder were repatriated to their own countries. The Belgian and Dutch volunteers lost their citizenship because they had served in a foreign army.
The first brigades were composed mostly of French, Belgian, Italian, and German volunteers, backed by a sizeable contingent of Polish miners from Northern France and Belgium. The XIth
were the first brigades formed. Later, the XIVth
Brigades were raised, mixing experienced soldiers with new volunteers. Smaller Brigades — the 86th
- were formed in late 1937 and 1938, mostly for temporary tactical reasons.
foreigners volunteered to defend the Spanish Republic, the vast majority of them with the International Brigades. Many were veterans of World War I. Their early engagements in 1936 during the Siege of Madrid
amply demonstrated their military and propaganda value.
The international volunteers were mainly socialists, communists, or others willing to accept communist authority, and a high proportion were Jewish
. Some were involved in the Barcelona May Days
fighting against leftist opponents of the Communists: the Workers' Party of Marxist Unification (POUM
) (''Partido Obrero de Unificación Marxista'', an anti-Stalinist
Marxist party) and the anarchist CNT
(CNT, Confederación Nacional del Trabajo) and FAI
(FAI, Iberian Anarchist Federation), who had strong support in Catalonia. These libertarian groups attracted fewer foreign volunteers.
To simplify communication, the battalions usually concentrated on people of the same nationality or language group. The battalions were often (formally, at least) named after inspirational people or events. From spring 1937 onwards, many battalions contained one Spanish volunteer company of about 150 men.
Later in the war, military discipline tightened and learning Spanish became mandatory. By decree of 23 September 1937, the International Brigades formally became units of the Spanish Foreign Legion
This made them subject to the Spanish Code of Military Justice. However, the Spanish Foreign Legion itself sided with the Nationalists throughout the coup and the civil war.
The same decree also specified that non-Spanish officers in the Brigades should not exceed Spanish ones by more than 50 percent.

Brigadistas by country of origin
Status after the war
After the Civil War was eventually won by the Nationalists, the brigaders were initially on the "wrong side" of history, especially as most of their home countries had right-wing governments (in France, for instance, the Popular Front
was not in power anymore).
However, since most of these countries soon found themselves at war with the very powers which had been supporting the Nationalists, the brigadistas gained some prestige as the first guard of the democracies, as having foreseen the danger of fascism and gone to fight it. Retrospectively, it was clear that the war in Spain was as much a precursor of the Second World War as a Spanish civil war.
Some glory therefore accrued to the volunteers (a great many of the survivors also fought during World War II), but this soon faded in the fear that it would promote communism
An exception is among some left-wingers, for example many anarchists
. Among these, the Brigades, or at least their leadership, are criticized for their role in suppressing the Spanish Revolution
. An example of a modern work that promotes this view is Ken Loach
's film ''Land and Freedom
''. A well-known contemporary account of the Spanish Civil War which also takes this view is George Orwell
's book ''Homage to Catalonia
was undivided until after the Second World War. At that time, the new communist state
, the German Democratic Republic
, began to create a national identity
which was separate from and antithetical to the former Nazi Germany
. The Spanish Civil War, and especially the role of the International Brigades, became a substantial part of East Germany's memorial rituals because of the substantial numbers of German communists who had served in the brigades. These showcased a commitment by many Germans to antifascism
at a time when Germany and Nazism were often conflated.
Survivors of the Mackenzie-Papineau Battalion
were often investigated by the Royal Canadian Mounted Police
and denied employment when they returned to Canada. Some were prevented from serving in the military during the Second World War due to "political unreliability".
In 1995 a monument to veterans of the war was built near Ontario
's provincial parliament. On 12 February 2000, a bronze statue "The Spirit of the Republic" by sculptor Jack Harman
, based on an original poster from the Spanish Republic, was placed on the grounds of the British Columbia
Legislature. In 2001, the few remaining Canadian veterans of the Spanish Civil War dedicated a monument to Canadian members of the International Brigades in Ottawa's Green Island Park
In Switzerland, public sympathy was high for the Republican cause, but the federal government banned all fundraising and recruiting activities a month after the start of the war as part of the country's long-standing policy of neutrality
Around 800 Swiss volunteers joined the International Brigades, among them a small number of women.
[ Sixty percent of Swiss volunteers identified as communists, while the others included socialists, anarchists and antifascists.] [
Some 170 Swiss volunteers were killed in the war.] [ The survivors were tried by military courts upon their return to Switzerland for violating the criminal prohibition on foreign military service.] [ The courts pronounced 420 sentences which ranged from around two weeks to four years in prison, and often also stripped the convicts of their political rights. In the judgment of Swiss historian Mauro Cerutti, volunteers were punished more harshly in Switzerland than in any other democratic country.] [
Motions to pardon the Swiss brigaders on the account that they fought for a just cause have been repeatedly introduced in the Swiss federal parliament. A first such proposal was defeated in 1939 on neutrality grounds.] [ In 2002, Parliament again rejected a pardon of the Swiss war volunteers, with a majority arguing that they broke a law that remains in effect to this day. In March 2009, Parliament adopted the third bill of pardon, retroactively rehabilitating Swiss brigades, only a handful of whom were still alive.
On disbandment, 305 British volunteers left Spain.
They arrived at Victoria Station on 7 December, to be met by a crowd of supporters including Clement Attlee, Stafford Cripps, Willie Gallacher, and Will Lawther.
The last surviving British member of the International Brigades, Geoffrey Servante, died in April 2019 aged 99.
In the United States, the returned volunteers were labeled "premature anti-fascists" by the FBI, denied promotion during service in the U.S. military during World War II, and pursued by Congressional committees during the Red Scare of 1947–1957.
[Bernard Knox] However, threats of loss of citizenship were not carried out.

On 26 January 1996, the Spanish government gave Spanish citizenship to the 600 or so remaining Brigadistas, fulfilling a promise made by Prime Minister Juan Negrín in 1938.
In 1996, Jacques Chirac, then French President, granted the former French members of the International Brigades the legal status of former service personnel ("ancient combatants") following the request of two French communist Members of Parliament, Lefort and Asensi, both children of volunteers. Before 1996, the same request was turned down several times including by François Mitterrand, the former Socialist President.
Symbolism and heraldry
The International Brigades were inheritors of a socialist aesthetic. The flags featured the colors of the Spanish Republic: red, yellow and purple, often along with socialist symbols (red flags, hammer and sickle, fist). The emblem of the brigades themselves was the three-pointed red star, which is often featured.
