The Destruction of Guernica

On 19 July 1936, shortly after his declaration of martial law in Pamplona, Emilio Mola called a meeting of the mayors of the province of Navarre. What he told them would characterise his subsequent treatment of the Basque Country. He said: ‘It is necessary to spread terror. We have to create the impression of mastery, eliminating without scruples or hesitation all those who do not think as we do. There can be no cowardice. If we vacillate one moment and fail to proceed with the greatest determination, we will not win. Anyone who helps or hides a communist or a supporter of the Popular Front will be shot.’1 What this meant for the Basques was soon revealed by an early precursor of what was to happen to Durango and Guernica in the spring of 1937. On 22 July, two aircraft from Vitoria bombed the village square of Otxandio in the south of Vizcaya, killing more than sixty people of whom at least twenty-four were children and mutilating a further eighty. In justification, the rebel command in Vitoria announced that ‘our aircraft have struck a heavy blow against a group of rebels gathered in the rearguard at Otxandio’.2 Otxandio is the Basque name of the village called Ochandiano in Spanish.

Because of his early reverses in the sierra north of Madrid, Mola’s first major campaign against the Basque Country did not begin until after the arrival of German and Italian aid in early August which enabled him to launch an attack on the province of Guipúzcoa and Franco to begin the march on Madrid. Already on 23 July, Carlist troops from Navarra had entered the southern part of Guipúzcoa through Cegama and Segura. Although they encountered no resistance, in Cegama and Segura, they sacked the headquarters of Republican parties and the Batzoki (offices) of the Partido Nacionalista Vasco (Basque Nationalist Party). Now, in early August, Mola began a campaign to capture Irún and the provincial capital San Sebastian and cut off Guipúzcoa from the French border. Irún and Fuenterrabía were being shelled from the sea and attacked daily by German and Italian bombers. The British (born in South Africa) correspondent George Steer noted that the rebels had dropped pamphlets threatening to deal with the population as they had dealt with those in Badajoz. The use of pamphlets describing earlier atrocities as a threat of what would happen if surrender were not immediate would happen again eight months later when the experience of Guernica would be used as a threat against Bilbao. San Sebastián was also heavily shelled from the sea. Irún’s poorly armed and untrained militia defenders fought bravely but were overwhelmed on 3 September. Thousands of panic-stricken refugees fled across the international bridge to France. The last defenders, largely anarchists enraged by their lack of ammunition, shot some rightist prisoners in Fuenterrabía and set parts of Irún on fire.3

Rebel troops and Carlists occupied San Sebastián on Sunday 13 September and by the end of the month, virtually all of Guipúzcoa was in Mola’s hands.4 A substantial number of the city’s 80,000 inhabitants had fled either westward towards Vizcaya or else by boat to France. Nevertheless, the number of executions in San Sebastián would be the highest carried out by the rebels in any Basque city. Mass detentions began immediately, beginning with the wounded Republicans who, given the seriousness of their condition, could not be evacuated from the Hospital Militar. Soon the prisons of Ondarreta and Zapatari, the offices of the Falange in the centre of the city, the San José hospice and the Kursaal cinema were all bursting to the seams with detainees.5 Among the hundreds of executions that took place in Guipúzcoa, the most notorious were those of thirteen Basque priests, which were carried out at the behest of the Carlists. In total, the rebels murdered at least sixteen priests in the entire Basque region and imprisoned and tortured many more. Father Alberto Onaindía, whose brother was one of the victims, said prophetically, ‘If this was how the army behaved with the Basque clergy, what would it be like for civilians!’ The testimony of Father Onaindía (a friend of the Lehendakari or President José María Aguirre) would be crucial in dismantling the lies later propagated by the rebels about the bombing of Guernica.6

Even before the fall of San Sebastián, Mola had initiated secret negotiations with the Partido Nacionalista Vasco (PNV). Mola hoped for a peaceful surrender of Vizcaya in return for a promise not to destroy the provincial capital Bilbao and a guarantee of no subsequent repression. In the light of what had happened after the captures of Irún and San Sebastián, the PNV leadership had no reason to believe Mola’s promises. In the course of the negotiations, appeals were made to Mola not to bomb Bilbao on the grounds that to do so would provoke reprisals against the two and a half thousand imprisoned rightists in the city.7 On 25 and 26 September, major bombing raids on Bilbao caused dozens of deaths and mutilations of women and children which, as predicted, provoked an outburst of rage from the starving population. Two prison ships were assaulted and sixty rightist detainees murdered.

Rebel hostility to the Basque Country intensified after the concession of regional autonomy by Madrid on 1 October and the formation of a Basque government six days later. The newly elected President of the Basque government, José Antonio de Aguirre y Lecube, and his cabinet were sworn in at a ceremony before the Tree of Guernica, the symbol of Basque nationhood. In his speech Aguirre declared that ‘The tradition of our elders was once again reborn in us, and the sacred Tree that in Guernica grows, was no longer a relic, but became once again the living symbol of our history.’8

Sporadic bombing raids continued on Bilbao but nothing had prepared the city for the scale of another attack on 4 January. In an even more ferocious incursion into the city’s four prisons, 224 rightists were killed including several priests, most Carlists but some Basque Nationalists.9 As long as the siege of the capital was the principal rebel preoccupation, the Basque front remained static until late March 1937. However, the Republican victory at Guadalajara on 20 March 1937 finally undermined Franco’s belief that he could win the war at Madrid and imposed upon him a momentous strategic volte-face. The lesson to be drawn from contrasting the easy victory at Málaga in early February with the immense cost of the battles around Madrid at Jarama and Guadalajara was clear. The Republic was concentrating its best-trained and equipped troops in the centre of Spain and leaving other fronts relatively neglected. Against the Republican army of the Centre, the military rebels were achieving only small gains at the cost of massive bloodshed while against the militias of the periphery, substantial triumphs could come relatively cheaply. Thus, there was a case for desisting from the obsessive concentration on Madrid and destroying the Republic by instalments elsewhere. This was the view of Colonel Juan Vigón Suerodiaz, chief of Mola’s general staff, who argued for priority to be given to operations in the north so that the rebel cause might be strengthened by the seizure of the coal, iron and steel reserves and the armaments factories of the Basque provinces.10

Franco initially remained obsessed with Madrid. The commander of the Condor Legion, General Hugo Sperrle, put forward similar arguments with greater insistence. It took the news of the defeat at Guadalajara to change Franco’s thinking, and for him to succumb to the pressure from Sperrle and Vigón and accept that the defeat of the Republic must be sought somewhere other than the outskirts of Madrid. Sperrle persuaded him that resistance in the north would be slight, with promises about the likely impact of concerted airborne ground attacks by the Condor Legion. On 22 March, the Generalísimo presented Kindelán with a sketchy outline of his immediate plans for a huge new force to be massed to attack and take Bilbao. On 23 March, he summoned Mola to Salamanca and gave him specific orders for the assault on Bilbao which derived from Vigón’s suggestions and Sperrle’s proposals.11

The operational details were hammered out at meetings held on 24 and 26 March involving General Alfredo Kindelán, as head of Franco’s air force, General José Solchaga and General José López Pinto as field commanders, Vigón as Mola’s chief of staff and Colonel Wolfram von Richthofen, the Condor Legion’s chief of staff. Richthofen explained to his Spanish counterparts the novel strategy of ‘close air support’, using aircraft for sustained ground attack to smash the morale of opposing troops. Accordingly, arrangements were made at these meetings for continuous and rapid liaison between the headquarters of the Spanish ground forces and the Condor Legion. Two hours before any attack, the air force commanders would inform the ground headquarters in order for the necessary coordination to take place. It was also agreed at these meetings that attacks would proceed ‘without taking into account the civilian population’.12

Mola gathered a large army consisting of African Army units, of the Carlist militias or requetés now fully militarised as the Navarrese Brigades and of mixed Spanish-Italian brigades. It was backed by the air support of the small but well-equipped Condor Legion and of units of the Italian Aviazione Legionaria under Richthofen’s command.13 After Guadalajara, the Germans were keen to show their superiority over the Italians and to practise and develop their techniques of ground attack from the air. In this context, the relationships between Mola and Sperrle and between their chiefs of staff, Vigón and von Richthofen, were constant and close if not exactly cordial. The German government had made it clear in late October 1936 that the commander of the Condor Legion would be solely responsible to Franco. Sperrle was meticulous about observing that hierarchy and, in consequence, enjoyed generally good relations with Franco.14

In practice, however, the need to integrate joint air/ground operations on an hour-by-hour basis rendered liaison with Salamanca impracticable. So, content with Sperrle’s deferential manner, Franco allowed him a free hand to liaise directly with Mola and Vigón, except on major issues. Franco was delighted to be able to consider the crack Condor Legion as part of his forces and to sit back and take the credit for its achievements. In the field, Mola and Vigón were also happy to accept the help and advice of Sperrle and Richthofen and the consequence was that, with Franco’s conscious acquiescence, the Germans had the decisive voice in the campaign. Sperrle wrote in 1939, ‘All suggestions made by the Condor Legion for the conduct of the war were accepted gratefully and followed.’ While the advance was being planned, von Richthofen wrote in his diary on 24 March, ‘we are practically in charge of the entire business without any of the responsibility’ and, on 28 March, ‘I am an omnipotent and effective commander (Feldherr) … and I have established effective ground/air command.’15

On 31 March, Mola arrived in Vitoria to put the final touches to the offensive that was to be launched on the following day. He began by deploying the weapon of mass fear which had been so effective for Franco in the advance on Madrid of the African columns. He issued a proclamation that was both broadcast and printed in a leaflet dropped on the main towns. It contained the following threat: ‘If your submission is not immediate, I will raze Vizcaya to the ground, beginning with the industries of war. I have ample means to do so.’16 In a similar spirit of crushing enemy morale, he ordered the execution of sixteen prisoners in Vitoria. The fact that among them were several popular local figures including the Alcalde, Teodoro González de Zárate, provoked protests from the local right.17 This act of gratuitous violence was followed by a massive four-day artillery and aircraft bombardment of eastern Vizcaya in which the small picturesque country town of Durango was destroyed by two bombing attacks carried out by four bombers and nine fighters of the Italian Aviazione Legionaria. Unlike Guernica, after the bombing, Durango remained under the jurisdiction of the Basque Government until 28 April. This permitted an investigation to identify the victims. As a result, the government published the figure of 258 civilians, 127 died during the bombing and at least a further 131 who died shortly after as a consequence of their wounds. Among the dead were fourteen nuns and two priests. Subsequent exhaustive research by Jon Irazabal Agirre reached the figure of 336 dead, of whom 276 could be identified and a further 60 who could not. As was later to be the case with the more notorious bombing of Guernica, Salamanca denied that the raid on Durango had taken place and attributed the damage to the Basques themselves.18

Rebel progress in the first three days of Mola’s campaign was so slow that Sperrle sent a report to Kindelán in which he complained that ‘if the troops do not advance faster, we will not enter Bilbao’. Sperrle believed that Franco had retained too much artillery and infantry on the Madrid front.19 On 2 April, Sperrle and Richthofen complained about this to Mola. Equally anxious to speed things up, Mola suggested to Sperrle that the industries of Bilbao be destroyed. When the German commander asked why it made any sense to destroy industries which it was hoped to capture shortly after, Mola replied: ‘Spain is totally dominated by the industrial centres of Bilbao and Barcelona. Under such a domination, Spain can never be cleaned up. Spain has got too many industries which only produce discontent’, adding that ‘if half of Spain’s factories were destroyed by German bombers, the subsequent reconstruction of Spain would be greatly facilitated’. In response to the notion that Spain’s health required the elimination of the industrial proletariat, Sperrle pointed out that the German air forces in Spain would attack factories only when Franco gave them specific orders to do so. According to Richthofen, Mola told Vigón to issue the order. Richthofen said that it had to come from a higher authority. Mola then signed orders himself for attacks on Basque industrial targets. Richthofen agreed to bomb the explosives factory at Galdácano on the ‘next free day’. Sperrle and Richthofen, however, informed Franco and awaited his permission to carry out Mola’s orders. Sperrle even offered to put an aircraft at Franco’s disposal for him to come to Vitoria to discuss the situation.20

In expecting the entire north of Spain to fall in under three weeks, Franco and Mola had underestimated the determination of the Basques. They were both disconcerted by the slowness of the first stage of their advance towards Bilbao’s unfinished ‘iron ring’ of fortifications. By 8 April, the rebel forces had completed only the first part of their planned offensive. After intense bombing on 4 April, they occupied the village of Otxandio (where the Basques had temporarily established their field headquarters) and the heights to the north, which they had intended to do on the first day. Steep, wooded hills, poor roads and heavy rain and fog had held up the advance of General Solchaga’s troops. Franco visited the front, ostensibly to witness the triumph, but in fact to resolve the differences between Mola and Sperrle.21 While he was in the north, Mola announced that it would be necessary ‘to destroy systematically the war industries of the province of Vizcaya. To this effect, on 9 April we will begin the complete destruction of the power station at Burceña, the steelworks of Euskalduna and the explosives factory of Galdácano.’ It seems that Franco had given permission for the partial implementation of the order signed by Mola on 2 April.22 The dogged Basque retreat continued to exact a high price from the attacking forces but the terror provoked by artillery and aerial bombardment and political divisions within the Republican ranks ensured the gradual collapse of Basque resistance.23

In the early days of the Basque offensive, on the evening of 4 April, Franco received the Italian Ambassador Cantalupo and explained with surprising candour the philosophy of his war effort: ‘Ambassador, Franco does not make war on Spain but is merely carrying out the liberation of Spain … I must not exterminate an enemy nor destroy cities, nor fields, nor industries nor production. That is why I cannot hurry.’24 Franco had no doubts that the ‘liberation’ of his ‘Spain’ signified, as his actions showed, the thorough-going repression of all liberal and leftist elements. However, his remarks suggest that he doubted the wisdom of Mola’s manic determination to annihilate Basque industry on which Sperrle had consulted him. The differences between Franco and Mola over the appropriate targets in the northern campaign do not indicate humanitarian preoccupations on the part of the Generalísimo. For Franco, ‘Spain’ had an entirely partisan meaning. He was reluctant to damage the material interests of his ‘Spain’ and that included the Basque industrial base, arms factories and mineral wealth.25 Franco explained to Cantalupo the destruction of Durango four days previously by aircraft of the Condor Legion flying at his orders. ‘Others might think that when my aircraft bomb red cities I am making a war like any other, but that is not so. My generals and I are Spaniards and we suffer in fulfilling the duty which the Patria has assigned to us but we must go on fulfilling it.’26

Nevertheless, Franco was perplexed by the sluggish progress of the campaign in the north. Sperrle and Richthofen were also frustrated with the slowness of the advance. Since the beginning of the campaign, Richthofen had experimented with terror bombing to break the morale of the civilian population and to destroy road communications where they passed through population centres. This tactic had begun with the destruction of Durango on 31 March and been followed up by the attack on Otxandio. When he told Cantalupo that, in bombing Republican towns, he and his generals were merely fulfilling their patriotic duty, Franco was admitting that he approved of such terror bombing. How fully Franco understood the military theory behind German strategy is another matter. On 12 April, Franco disconcerted Sperrle by requesting that he send him all the aircraft that he was not using in the north to be used around Madrid. Under orders from Berlin not to split his forces, Sperrle offered to leave the Basque campaign and transfer the entire Condor Legion to central Spain. Only after Colonel von Funck, the German military attaché in Salamanca, had laboriously explained to him the strategic thinking behind the German operation did Franco refuse the offer and order Sperrle to remain in the north.27 The episode reveals not only the limitations of the Generalísimo’s strategic vision, but also that Sperrle was still directly responsible to him.

On 20 April, the rebels began the second phase of their offensive and German air support was to play an even more crucial role. Sperrle, Richthofen, Mola and Vigón were sufficiently frustrated by the slowness of the advance to talk again of reducing Bilbao to ‘debris and ash’.28 In the event, the great morale-destroying blow would fall not on the Basque capital but on another smaller, more manageable but equally significant target. By 24 April, after merciless air bombardment and artillery pounding, the Basque forces were falling back in some disarray.29 In the course of 25 April, as indeed throughout the entire campaign, Richthofen and Vigón were in constant contact by telephone coordinating aircraft, artillery and infantry. They agreed on the need to try to bottle up the retreating Basques around Guernica and Marquina. In the evening of 25 April, Richthofen again telephoned Vigón and arranged to see him at 7 a.m. the following morning. He wrote in his diary ‘units ready for tomorrow’.30 On the night of 25 April, presumably on Mola’s instructions, the rebel radio at Salamanca broadcast the following warning to the Basque people: ‘Franco is about to deliver a mighty blow against which all resistance is useless. Basques! Surrender now and your lives will be spared’.31

Richthofen and Vigón talked again at 6 a.m. on Monday 26 April and then met, as arranged, at 7 a.m. After close consulation with Vigón, Richthofen organised a series of bombing attacks aimed at impeding the retreat of the Basque forces. He seems to have decided to combine the tactical objective of blocking the retreat south of Guernica near Marquina with the broader strategic coup of the devastating blow to which Mola’s broadcast had referred. Richthofen wrote in his diary of an implacable attack on the roads, bridge and suburbs of Guernica. ‘There things must be closed up, it is necessary to secure finally a triumph over enemy personnel and material.’32 Franco had made sufficient comments since 18 July 1936 about his belief that the Civil War would be won on morale for him to have few objections. If he had disapproved of what happened at Durango, Otxandio and other villages, he had had ample time to put a stop to Richthofen’s programme. His remarks to Cantalupo, in fact, make it clear that he approved and indeed took pride in what was happening.

From 4.40 to 7.45 in the late afternoon and early evening of 26 April, which was market day in the small town of Guernica, a blow consistent with Mola’s threat was struck. With the normal population joined by refugees and peasants coming in for the market, there were at least ten thousand people in Guernica on that day. The military authorities had tried to suspend the market because of the war but many peasants from surrounding hamlets had arrived as usual. Moreover, large numbers of people had come from Bilbao in the hope of being able to buy food at the market. The town had no anti-aircraft defences. It was annihilated in three hours of sustained bomb attacks by aircraft of the Condor Legion and the Italian Aviazzione Legionaria under the overall command of Richthofen. The raid was carried out by the following aircraft: twenty-three Junkers Ju 52 trimotor bombers, four new He 111 twin-engine bombers, ten Heinkel He 51 biplane fighters, three Savoia-Marchetti S.81 Pipistrello trimotor bombers and one Dornier Do 17 twin-engine bomber, escorted by twelve Fiat C.R.32 biplane fighters and possibly six of the first ever Messerschmitt Bf109 fighters.33 It was an operation on a scale that could hardly have been organised by the Germans behind the backs of the Spanish staff with whom there was, in any case, constant liaison. Terrified civilians who fled into the surrounding fields were strafed by the machine-guns of Heinkel He 51s in order to force them back into the centre of the town. The number of victims will never be known for certain because of the chaos and the fact that the rebels had captured the town before the debris was cleared.
