Soviet Union During the Spanish Civil War, the Soviet Union provided military equipment and support to the Republicans, being the only nation to provide such aid alongside Mexico. To pay for these supplies, the Republicans spent US$500 million in gold reserves. In 1936, the
Bank of Spain had the world's fourth-largest gold reserve, worth approximately US$750 million, although some of its assets were frozen by the French and British governments. According to an official Soviet source, more than 2,000 members of the
Soviet Armed Forces served in Spain, many of them being awarded the
Soviet honours and 59 being awarded the title
Hero of the Soviet Union. The largest number of Soviets in Spain at any time is believed to have been 700, and the total during the war is thought to have been between 2,000 and 3,000; they were primarily tank crews and pilots, and fought in direct combat. Estimates for the pilots of
Spanish Republican Air Force from the Soviet Union who took part in the conflict are given at 1,000. The Republicans sent their gold reserve to the Soviet Union to pay for arms and supplies. The reserve was worth $500,000,000 in 1939 prices. In 1956, the Soviet Union announced that Spain still owed it $50,000,000. Other estimates of Soviet and
Comintern aid totaled £81,000,000 ($405,000,000) at 1939 values. The German military attaché estimated that Soviet and Comintern aid amounted to the following: • 242 aircraft, • 703 pieces of artillery, • 731 tanks, • 1,386 trucks, • 300 armored cars • 15,000 heavy machine guns, • 500,000 rifles, • 30,000 sub-machine guns, • 4,000,000 artillery shells, • 1,000,000,000 machine gun cartridges, • over 69,000 tons of war material, and • over 29,000 tons of ammunition. Much of the material was purchased in
France,
Czechoslovakia, the
United States, the
United Kingdom and
Mexico. The Republicans were continuously swindled and shortchanged in their dealings with the Soviets, and the Soviet Union's conduct was characterised by the historian Gerald Howson characterised as "treacherous and indefensible". The Republicans also made poor choices in buying ammunition. The arms trade has a standard that with every rifle, 1,000 rounds of ammunition are included; with every machine gun, 10,000 rounds are included; and with every artillery piece, 2,400 shells are included to prevent the hardware from becoming useless by a lack of ammunition. However, many of the purchases fell far short of that standard. Soviet foreign policy considered collective security against German fascism to be a priority, and the Comintern had agreed a similar approach in 1934. It walked a thin line between pleasing France and not being seen to hinder both the
world revolution and communist ideals. It was also the time of the first significant Soviet trials of the
Old Bolsheviks. The Soviet press and opposition groups were entirely against non-interventionism. Another significant Soviet involvement was the activity of the People's Commissariat for Internal Affairs (
NKVD) in the Republican rearguard. Communist figures including
Vittorio Vidali ("Comandante Contreras"),
Iosif Grigulevich,
Mikhail Koltsov and most prominently
Aleksandr Mikhailovich Orlov led operations that included the murders of the Catalan
anti-Stalinist communist politician
Andrés Nin, the socialist journalist
Mark Rein and the independent left-wing activist
José Robles. Another NKVD-led operation was the shooting down in December 1936 of the French aircraft in which the delegate of the
International Committee of the Red Cross (ICRC),
Georges Henny, carried extensive documentation on the
Paracuellos massacres to France.
Poland Polish arms sales to Republican Spain took place between September 1936 and February 1939. Politically,
Poland did not support any side of the war, but over time, the Polish government increasingly tended to prefer the Nationalists. Sales to the Republicans were motivated exclusively by economic interest. Since Poland was bound by
non-intervention obligations, Polish governmental officials and the military disguised sales as commercial transactions mediated by international brokers and targeting customers in various countries, principally in
Latin America; 54 shipments from
Danzig and
Gdynia were identified. Most hardware were obsolete and worn-out second-rate but some modern arms were also delivered; all were 20-30% overpriced. Polish sales amounted to $40 million and constituted some 5-7% of the overall Republican military spendings, but in terms of quantity certain categories of weaponry like
machine guns, they might have accounted for 50% of all arms delivered. After the Soviet Union, Poland was the second largest arms supplier for the Republic. After the Soviet Union,
Italy and
Germany, Poland was the fourth-largest arms supplier to Spain. Poland also sold 44 obsolete or non-combat aircraft to the Nationalists via Portugal (20
PWS-10 training fighters, 20
Breguet XIX light bombers, 4
RWD-13 liaison aircraft).
Greece Greece maintained formal diplomatic relations with the Republic, but
Ioannis Metaxas's dictatorship sympathised with the Nationalists. Greece joined the non-intervention policy in August 1936, but from the onset, the government connived at arms sales to both sides. The official vendor was
Pyrkal, or Greek Powder and Cartridge Company (GPCC), and the key personality behind the deal was the head of the GPCC,
Prodromos Bodosakis-Athanasiadis. The company partially took advantage of the earlier Schacht Plan, a German-Greek credit agreement that enabled Greek purchases from
Rheinmetall-Borsig; some German products were later re-exported to Republican Spain. However, GPCC was selling also its own arms, as the company operated a number of factories and partially from Spanish sales, it became the largest Greek company. Most Greek sales went to the Republic. For the Spaniards the deals were negotiated by Grigori Rosenberg, the son of
well-known Soviet diplomat, and Máximo José Kahn Mussabaun, the Spanish representative in the
Thessaloniki consulate. Shipments set off usually from
Piraeus; were camouflaged at a deserted island; and, with changed flags, they proceeded officially to ports in Mexico. It is known that sales continued from August 1936 to at least November 1938. The exact number of shipments is unknown but remained significant since by November 1937, 34 Greek ships were declared to be non-compliant with the non-intervention agreement, and the Nationalist Navy seized 21 vessels in 1938 alone. Details of sales to the Nationalists are unclear, but they were known to be by far fewer. The total worth of Greek sales is unknown. One author claims that in 1937 alone, GPCC shipments amounted to $10.9 million for the Republicans and $2.7 million for the Nationalists and that in late 1937 Bodosakis signed another contract with the Republicans for £2.1 million (around $10 million), but it is not clear whether the ammunition that was contracted was delivered. The arms sold included artillery (such as 30 pieces of 155 mm guns), machine guns (at least 400), cartridges (at least 11 m), bombs (at least 1,500) and explosives (at least 38 tons of TNT).
AEKKEA-RAAB, a Greek aviation company, also sold at least 60 aircraft to the Republican Air Force, consisting of
R-29 fighters and R-33 trainers.
Mexico The Mexican government supported fully and publicly the Spanish Republic. Mexico refused to follow the French and British non-intervention proposals. Mexican President
Lázaro Cárdenas saw the war as similar as the
Mexican Revolution, although Mexican society was divided, with support for each faction in the army. The Mexican government's attitude was an immense moral comfort to the Republic, especially since major
Latin American governments (
Colombia,
Brazil,
Nicaragua,
El Salvador,
Haiti,
Dominican Republic,
Bolivia,
Argentina,
Chile and
Peru) sympathised more or less openly with the Nationalists. However, Mexican aid could mean relatively little in practical terms since the French border was closed, and the German, Italian and Portuguese dictators remained free to supply the Nationalists with a quality and a quantity of weapons that went far beyond the power of Mexico, which could furnish only $2,000,000 in aid. Mexico provided only some material assistance, which included rifles, food and a few American-made aircraft, such as the
Bellanca CH-300 and the
Spartan Zeus, which had served in the
Mexican Air Force.
France On 21 August 1936, France signed the Non-Intervention Agreement. However,
Leon Blum's government provided some aircraft to the Republicans by covert means.
Potez 540 bomber aircraft (nicknamed the "Flying Coffin") by Spanish Republican pilots,
Dewoitine aircraft, and
Loire 46 fighter aircraft were sent from 7 August to December 1936 to Republican forces. The French also sent pilots and engineers to the Republicans. Also, until 8 September 1936, aircraft could freely pass from France into Spain if they had been bought in other countries. In total, France delivered 70 aircraft.
Other countries Other countries selling arms to the Republicans included
Czechoslovakia and
Estonia. Also, $2,000,000 came from the
United States for humanitarian purposes.
International volunteers Volunteers from many countries fought in Spain, most of them for the Republicans. About 32,000 fought in the
International Brigades, including the American
Lincoln Battalion and the Canadian
Mackenzie–Papineau Battalion, which were organised in close conjunction with the Comintern to aid the Spanish Republicans. Perhaps another 3,000 fought as members of the
Confederación Nacional del Trabajo (CNT) and the Workers' Party of Marxist Unification (
POUM) militias. Those fighting with POUM most famously included
George Orwell and the small
ILP Contingent. Around 2,000 Portuguese leftists fought for the Republicans and were spread throughout different units. "Spain" became the
cause célèbre for the left-leaning intelligentsia across the
Western world, and many prominent artists and writers entered the Republic's service. As well, it attracted a large number of foreign left-wing working-class men for whom the war offered not only an idealistic adventure but also an escape from
Great Depression unemployment. Among the more famous foreigners participating for the Republic was
George Orwell, who went on to write about his experiences in
Homage to Catalonia. Orwell's novel
Animal Farm was loosely inspired by his experiences and those of other members of POUM at the hands of
Stalinists when
infighting arose within the Popular Front. His experiences also inspired the torture scenes in his
Nineteen Eighty-Four.
Ernest Hemingway's novel
For Whom the Bell Tolls was inspired by his experiences in Spain.
George Seldes reported on the war for the
New York Post. The third part of
Laurie Lee's autobiographical trilogy,
A Moment of War, is also based on his Civil War experiences.
Norman Bethune used the opportunity to develop the special skills of
battlefield medicine. As a casual visitor,
Errol Flynn used a fake report of his death at the battlefront to promote his movies. In the Philippines, a pro-Republican magazine,
Democracia, had writers, including antifascist Spaniards, Filipino-Spaniards and Filipino progressives such as
Pedro Abad Santos, the chairman of the
Socialist Party of the Philippines, and Bishop
Gregorio Aglipay, of the
Philippine Independent Church.
International Brigades Probably 32,000 foreigners fought in the communist
International Brigades. An estimated 3,000 volunteers fought in other Republican forces during the conflict. Additionally, about 10,000 foreigners participated in medical, nursing and engineering capacities. The International Brigades included 9,000 Frenchmen, of whom 1,000 died; 5,000 Germans and Austrians, of whom 2,000 died; The third-highest number was from Italy with 3,350 men. Then came Poland, with about 3,000 men. Then the United States (2,800 men with 900 killed and 1,500 wounded) and the United Kingdom (2,000 with 500 killed and 1,200 wounded). There were also 1,500 Czechoslovaks, 1,500
Yugoslavs, 1,500 Canadians, 1,000 Hungarians, and 1,000 Scandinavians (about half of whom were Swedes), 100 Chinese also volunteered, as well as another 800 Swiss, 300 of whom would later be killed. The rest came from a claimed 53 countries About 90 Mexicans participated, and
at least 80 Irishmen (fighting mostly within the International Brigades). Future Albanian Prime Minister
Mehmet Shehu would also serve as a volunteer for the Republicans in the Spanish Civil War. It has been estimated that
between 3,000 and 10,000 of the volunteers were Jews from various countries. About 200 volunteers were from Palestine (of both Jewish and Arab origin). Historians debate the presence of 1000 Arab volunteers. However, the Catalan historian Andreu Castells, who has conducted extensive research into the topic, found 716 recorded cases. Many of the Arabs who volunteered were registered as French citizens, as many North African countries were still under colonial rule when the Spanish Civil War broke out. Additionally, Arabic names were commonly misspelled and therefore registered multiple times. Roughly half of the Arabs who volunteered in Spain were Algerian, with 493 joining the Republican forces, of which 332 survived. Alongside those there were 211 Moroccans, 11 Syrians, four Palestinians including Palestinian journalist Najati Sidqi, three Egyptians, two Iraqis and one Lebanese man also took up arms for the International Brigades. The motivations behind Arab participation in the Spanish Civil War are varied. However, most likely they saw that a Republican victory in Spain would lead to the decolonisation of the Arab world in the longer term. Approximately a third of Irishmen who fought for Republicans died, primarily socialists, trade unionists, and former IRA members. The "
Connolly Column" of the International Brigades was named after
James Connolly, an Irish socialist leader who had been executed by the British for participating in the 1916
Easter Rising. Both Nationalist and Republican Irish Volunteers were led by former
Irish Republican Army members. A 47-year-old man from
Turkey named Mustafa İbrahim would serve in the 14th International Brigade ==Patriotism invoked to oppose invaders==
