A Secret Pact: Germany Enters the Spanish Civil War
In July 1936, a military coup in Spain plunged the nation into a brutal civil war. General Francisco Franco's Nationalist faction, facing fierce resistance from the Republican government, desperately sought international aid. Their plea reached Adolf Hitler, who saw a unique opportunity to advance Nazi Germany's strategic interests.
Operation Magic Fire: The Covert Airlift Begins
Hitler quickly decided to support Franco, but with a crucial caveat: Germany's involvement had to remain a secret to avoid igniting a wider European conflict. The initial mission, codenamed Operation Magic Fire, was to airlift Franco's elite Army of Africa from Spanish Morocco to the mainland. This required a massive, clandestine operation.
Using civilian-marked Junkers Ju 52 transport planes flown by Luft Hansa pilots—all while hiding the mission from German foreign and economic ministries—Germany began moving troops. The operation was funded with three million Reichsmarks, funnelled through dummy corporations to obscure its true nature. Even the German volunteers themselves were initially unaware of their destination, believing they were merely trainers.
The covert airlift was a resounding success. In just two weeks, nearly 2,500 troops crossed the Strait of Gibraltar. By its official end in October, over 13,500 soldiers, 127 machine guns, and 36 field guns had been transported, fundamentally shifting the balance of power in the war.
The Birth of the Condor Legion
As German involvement deepened, encompassing not just the air force but elements of the army and navy, the scope expanded from mere transport and training to active combat. Recognizing Franco's government in September 1936, Berlin reorganized its efforts. What began as 'Operation Magic Fire' and later 'Operation Guido' was formally christened the 'Condor Legion' by Hermann Göring.
Hitler's Many Motives
Why did Hitler commit Germany to such a risky intervention? His motivations were multi-faceted. He sought to divert attention from Germany's rearmament, test his nascent military, prevent the spread of communism, and establish a friendly state in Spain that could disrupt British and French interests. There was also a keen economic interest: Spain's rich ore deposits could fuel German industry.
Hitler also skillfully used the conflict to tie Fascist Italy to Germany. By supporting Franco alongside Mussolini, he solidified the Rome-Berlin Axis, distracting Italy from Germany's own ambitions, particularly the annexation of Austria. This proxy war served as a complex diplomatic chess game on the world stage.
Forging a Modern Fighting Force
The Condor Legion was a formidable unit, initially comprising three squadrons of Ju 52 bombers and three squadrons of Heinkel He 51 fighters, alongside reconnaissance, anti-aircraft (Flakabteilung 88), and signals groups. Overall command fell to Hugo Sperrle, with ground elements led by Wilhelm Ritter von Thoma, operating early Panzer I tanks.
The early days of combat proved challenging. While German and Italian air units supported the Nationalist advance on Madrid, the increasing presence of Soviet-supplied Polikarpov I-15 and I-16 fighters for the Republicans exposed the limitations of early German aircraft like the He 51 biplanes and Ju 52s, especially in air-to-air engagements.
Germany swiftly responded by deploying newer, more advanced aircraft prototypes. The iconic Messerschmitt Bf 109 fighter, the potent Heinkel He 111 medium bomber, and the terrifying Henschel Hs 123 dive bomber all saw their first active service and refinement in Spain. These trials were crucial, as these aircraft would later form the backbone of the Luftwaffe in World War II.
The Horror of Guernica: A Precedent for Total War
The most infamous operation of the Condor Legion came during the Biscay campaign, part of the 'War in the North.' On April 26, 1937, under the command of Wolfram von Richthofen, waves of Ju 52 and He 111 planes unleashed a devastating bombing and strafing attack on the Basque town of Guernica.
Guernica was not a significant military target; it was a civilian center, filled with refugees. The attack, known as Operation Rügen, was a deliberate act of terror—a test of 'area bombing' designed to break civilian morale and disrupt retreating forces. The exact number of casualties remains disputed, but hundreds perished in the inferno.
Reports from journalists like George Steer of The Times quickly exposed Germany's direct involvement, revealing bomb fragments stamped with the German imperial eagle. The global outrage was immediate and profound. Guernica became a stark symbol of the new, brutal face of warfare, where air power could decimate towns and their populations.
From Brunete to the Ebro: Continued Campaigns
The Condor Legion continued to be instrumental in major battles across Spain. At Brunete, superior German aircraft like the Bf 109 proved decisive against Republican forces. In the northern campaigns, heavy aerial bombardment paved the way for Nationalist victories in Santander and Asturias, with the Legion expending vast quantities of bombs and ammunition.
During the Battle of the Ebro, the last major Republican offensive, Condor Legion reconnaissance detected troop buildups, though the warning was initially unheeded. Their subsequent air power, however, proved critical in repelling the Republican gains, showcasing the combined-arms tactics being perfected by the Germans.
Submarine Warfare and Maritime Patrols
Beyond the air, Germany's naval forces also played a clandestine role. The Maritime Reconnaissance Staffel 88, equipped with Heinkel He 60 floatplanes, patrolled Spanish waters, targeting enemy shipping and coastal communications. Under commanders like Martin Harlinghausen, known as 'Iron Gustav,' these units refined anti-shipping tactics.
Even more secretly, German U-boats operated under 'Operation Ursula,' disguised to hide their true origin. These submarines, like U-33 and U-34, conducted covert patrols and are controversially linked to the sinking of the Republican submarine C-3. This demonstrated Germany's willingness to flout international non-intervention agreements.
A Proving Ground for World War II
The Spanish Civil War was, for the Luftwaffe, an invaluable testing ground. As Hermann Göring himself later admitted at the Nuremberg trials, it provided the opportunity to 'test my young Luftwaffe at this opportunity in this or that technical respect.' Pilots gained vital combat experience, and aircraft like the Bf 109, He 111, and the Junkers Ju 87 'Stuka' dive bomber were rigorously evaluated and refined under battle conditions.
Tactical innovations were equally significant. The Legion's commanders, particularly Wolfram von Richthofen, experimented with close air support for ground troops, massed bombing raids, and strafing attacks—tactics that would become hallmarks of the Blitzkrieg. The effectiveness of the 88mm Flak 18 anti-aircraft gun, used against tanks and fortifications, also became strikingly clear.
The Condor Legion Comes Home
After nearly three years of combat, with Nationalist victory assured, the Condor Legion was dissolved in May 1939. Its surviving members returned to Germany aboard a fleet of KdF (Strength Through Joy) cruise ships, where they were greeted as heroes. Parades and ceremonies celebrated their success, though the darkest implications of their actions were yet to fully unfold across Europe.
Shame and Re-evaluation
Decades later, particularly after German reunification in the 1990s, public and official sentiment regarding the Condor Legion began to shift. The atrocities committed, especially the bombing of Guernica, became a source of national shame. In 1997, German President Roman Herzog issued an apology to the survivors of Guernica, extending 'a hand of friendship and reconciliation.'
This re-evaluation led to significant actions, including legislation in 1998 to remove all former Condor Legion members' names from German military bases. Even highly decorated pilots like Werner Mölders, who had volunteered for service, had their names removed from associations with military units, reflecting Germany's profound reckoning with its past.
In a poignant act of historical closure, on the 80th anniversary of the Guernica bombing in 2017, the Madrid City Council dismantled the Condor Legion mausoleum in Cementerio de la Almudena. The facade was replaced with simple name plaques for the seven soldiers entombed there—a final acknowledgment that heroism cannot erase the stain of infamy.
Commemorative Awards
Despite the secrecy, the German government established the Spanish Cross campaign medal in seven classes in April 1939, awarded to those who served. Legionnaires also received the Condor Legion Tank Badge and a special campaign medal from the Spanish authorities, recognizing their critical role in the Nationalist victory.

The Condor Legion marching in León during the Spanish Civil War
The Condor Legion (German: Legion Condor) was a unit of military personnel from the air force and army of Nazi Germany’s Wehrmacht which served with the Nationalist faction during the Spanish Civil War. The legion developed methods of strategic bombing that were used widely during the Second World War. The bombing of Guernica was the Condor Legion's most infamous operation. Hugo Sperrle commanded the unit's aircraft formations, and Wilhelm Ritter von Thoma commanded the ground element.
Military aid to Spain
Condor Legion
Condor Legion He 111E, 1939
After the 17 July 1936 military coup in Spain began the Spanish Civil War, the Nationalists requested support from Germany and Italy. The first request for German aircraft was made on 22 July, for 10 transport aircraft. Adolf Hitler decided to support the Nationalists on 25 or 26 July, but was wary of provoking a wider European war. The Reich Air Travel Ministry concluded that Nationalist forces would need at least 20 Junkers Ju 52s, flown by Luft Hansa pilots, to carry the Spanish Army of Africa from Spanish Morocco to Spain. This mission became known as Operation Magic Fire (German: Feuerzauber). To carry it out, a joint venture was created between the Spanish-German "Spanish-Moroccan Transport Company" (Spanish: Companía Hispano-Marroquí de Transporte, HISMA) dummy corporation and the German Raw Materials and Goods Purchasing Company (German: Rohstoffe-und-Waren-Einkaufsgesellschaft). German involvement was hidden from the foreign and the economic ministries, and was funded with three million Reichsmarks.
The organisation and the recruitment of German volunteers was also kept secret. The first contingent (86 men) left Germany on 1 August 1936. Unaware of their destination, they were accompanied by six biplane fighters, anti-aircraft guns and about 100 tons of other supplies. Many believed that the German troops would train the Nationalists and not engage in active combat.
The volunteers were stationed at Tablada Airfield near Seville and, with the support of German air transport, began the airlift of Francisco Franco's troops to Spain. Germany's involvement grew in September to encompass the Wehrmacht's other branches. Operation Magic Fire was renamed Operation Guido in November. The Kriegsmarine provided submarines in 24 October, also providing surface ships and co-ordinated movement of German supplies to Spain. German U-boats were dispatched to Spanish waters under the codename Ursula.

In the two weeks after 27 July, German transport moved nearly 2,500 Army of Africa troops to Spain. By 11 October (the mission's official end), 13,500 troops, 127 machine guns and 36 field guns had been transported to mainland Spain from Morocco. Over that period, there was a transition from training and supply missions to overt combat. The operation commander, Alexander von Scheele, was replaced by Walter Warlimont. In September, 86 tons of bombs, 40 Panzer I tanks and 122 personnel were deployed in Spain. They were accompanied by 108 aircraft from July to October, divided between aircraft for the Nationalist faction and planes for German volunteers in Spain.
German air crews supported the August-to-October 1936 Nationalist advance on Madrid, and the successful relief of the Siege of the Alcázar on 27 September 1936. Ultimately, the initial phase of the Siege of Madrid was unsuccessful. Soviet air support for the Republicans was growing, particularly through the supply of Polikarpov aircraft. Warlimont appealed to Germany to increase its support. After Berlin's recognition of Franco's government on 30 September, German efforts in Spain were reorganised and expanded. The existing command structure was replaced with the Winterübung Rügen; military units already in Spain were formed into a new legion, which was briefly called the Iron Rations (German: Eiserne Rationen) and the Iron Legion (German: Eiserne Legion) before Hermann Göring renamed it the Condor Legion (German: Legion Condor). The first German chargé d'affaires to Franco's government, General Wilhelm Faupel, arrived in November and was told not to interfere in military matters.
Motivation
In the years after the Spanish Civil War, Hitler gave several possible motives for German involvement. They included providing distraction from German rearmament, preventing the spread of communism to Western Europe, creating a state friendly to Germany to disrupt Britain and France, and creating possibilities for economic expansion. Although the Nationalist offensive on Madrid was abandoned in March 1937, a series of attacks on weaker Republican-controlled areas was supported by the Condor Legion. Despite prolonging the Civil War, it helped distract the other Western powers from Hitler's ambitions in Central Europe. The offensive on Biscay, a mining and industrial centre, helped to fuel German industry. In a speech at Würzburg on 27 June 1937, Hitler said that he supported Franco to gain control of Spanish ore.
Discussions about German objectives for intervention took place in January 1937. Germany was keen to avoid prompting a wider European war, which was a risk if it committed further resources to Spain. There was no consensus among German officials; Ernst von Weizsäcker of the German Foreign Office suggested that it was a matter of graceful withdrawal, and Göring said that Germany would never recognise a "red Spain". A joint Italian–German agreement said that the last shipments would be made no later than early February.
It has been speculated that Hitler used the Spanish Civil War to distract Benito Mussolini from Hitler's plans to annex Austria; the authoritarian, Catholic and anti-Nazi Vaterländische Front ran the government of Austria from 1933 to 1938, and had been allied with Mussolini. In 1934, the assassination of Austrian Chancellor Engelbert Dollfuss had given rise to Italian military assistance to prevent a German invasion.
A December 1936 communiqué from German ambassador to Rome Ulrich von Hassell said that Italy’s involvement in the Spanish Civil War kept it out of the Western powers' camp:
The role played by the Spanish conflict as regards Italy's relations with France and England could be similar to that of the Abyssinian conflict, bringing out clearly the actual, opposing interests of the powers and thus preventing Italy from being drawn into the net of the Western powers and used for their machinations ... All the more clearly will Italy recognize the advisability of confronting the Western powers shoulder to shoulder with Germany.
Military operations
Condor Legion
The Condor Legion originally consisted of the Kampfgruppe 88 with three squadrons of Ju 52 bombers and the Jagdgruppe 88, with three squadrons of Heinkel He 51 fighters; the reconnaissance Aufklärungsgruppe 88 supplemented by the Aufklärungsgruppe See 88, an anti-aircraft group (the Flakabteilung 88); and the Nachrichtenabteilung 88 signals group. The anti-aircraft guns used by Flakabteilung 88 were the standard German anti-aircraft guns of the time: the 8.8cm Flak 18, 3.7cm Flak 18 and 2cm Flak 30. Overall command was given to Hugo Sperrle, with Alexander Holle chief of staff. Scheele became a military attaché in Salamanca. Also operational were two armoured units under the command of Wilhelm Ritter von Thoma, with four Panzer I tanks each.
The Nationalists were supported by German and Italian units and material in the Battle of Madrid, but its military situation remained poor for them. Under orders from Francisco Franco, German and Italian aircraft began bombing raids on the city. The Germans were keen to observe the effects of bombing and the deliberate burning of civilian sites on a city. Offensives involving German aircraft, and the bombings, were unsuccessful. Growing Republican air superiority became increasingly apparent, particularly the strength of the Soviet Polikarpov I-15 and I-16 aircraft, but historian Hugh Thomas described their armaments as "primitive".
Faupel advocated the creation of a single German unit of 15,000 to 30,000 men in November and December 1936, which he believed would be enough to turn the tide of the war toward the Nationalists. Hans-Heinrich Dieckhoff said that this would be insufficient, and larger measures could provoke Spanish wrath. New aircraft were sent to the Condor Legion between late 1936 and early 1937, including Henschel Hs 123 dive bombers and prototypes of the Heinkel He 112 and Messerschmitt Bf 109; the latter was the most successful. The Heinkel He 111 was added to the bomber fleet, along with the Dornier Do 17 E and F types. Older aircraft were passed on to the Nationalists. By the end of 1936, about 7,000 Condor Legion personnel were in Spain.
German forces also operated in the Battle of Jarama, which began with a Nationalist offensive on 6 February 1937. It included German-supplied ground forces, including two batteries of machine guns, a tank division, and the Condor Legion's anti-aircraft guns. Bombing by Republican and Nationalist aircraft, including Ju 52s from the Legion, created a stalemate and demonstrated the inadequacy of Legion aircraft when faced with superior Soviet-made fighters. Von Thoma requested Irish nationalist support for a tank advance at one point. The use of He 51 and Ju 52s and the Legion's anti-aircraft guns in ground roles only partly mitigated the Nationalist defeat in the March Battle of Guadalajara. A joint Italian-German general staff had been set up in January 1937 to advise Franco on war planning. The defeat of a significant Italian force and growing Soviet superiority in tanks and aircraft led the Germans to support a plan to abandon the offensive on Madrid and concentrate a series of attacks on weaker Republican-controlled areas. Some concluded that motorised troops were less effective than they had been thought, and the inadequacy of the Italians as a fighting force had become apparent to the Germans.
Biscay campaign
The isolated area of Biscay, a predominantly-Basque region of northern Spain, was the most immediate target in what was called the War in the North. It was largely a Nationalist and Italian offensive, supported by a consistently re-equipping Condor Legion. The terrain was favourable, with planes coming over a range of mountains to the south which masked their entrance. Sperrle remained in Salamanca; Wolfram von Richthofen replaced Holle in January as deputy, and was in actual command. Since the Basque air force was limited, fighter aircraft were used in ground-attack roles rather than air-to-air combat. The Legion's air force initially attacked the towns of Otxandio and Durango. Durango had no anti-aircraft defence, and only a few other defences. According to the Basques, 250 civilians died there on 31 March (including a priest, nuns and the congregation at a church ceremony). The Germans, because of their air raids, were hated. The Basque ground forces were in full retreat towards Bilbao through the town of Guernica, which was bombed on 26 April in one of the war's most controversial attacks.
Guernica
Ruins of Guernica (1937)
In Operation Rügen, waves of Ju 52 and He 111 planes bombed and strafed targets in Guernica. The number of casualties is controversial, with perhaps 200 or 300 people killed; the Basques reported 1,654 dead and 889 wounded. Several explanations were given by the Nationalists, who blamed the attack on the Republicans, said that the attack was part of a prolonged offensive, or the Rentería bridge outside Guernica was the true target. The nature of the operation, however (including its formation and armaments), undermines the credibility of these explanations. Guernica was a clear target of the Condor Legion, rather than the Nationalists. The 11 July offensive against Bilbao was supported by Condor Legion ground units and extensive air operations, proving the Legion's worth to the Nationalist cause.
The first English-language media reports of the destruction of Guernica appeared two days after the attack. George Steer, a reporter for The Times who was covering the Spanish Civil War from inside the country, wrote the first full account. Steer's reporting set the tone for much of the subsequent reportage, noting clear German complicity in the action. Three small bomb cases stamped with the German imperial eagle made it clear that the German position of neutrality in the war and the signing of a non-intervention pact were meaningless, and German forces were actively participating in combat. Steer's report was syndicated worldwide, generating widespread shock, outrage and fear.
Other campaigns
The Condor Legion also took part in the Battle of Brunete, a Republican offensive designed to take the pressure off northern Spain where fighting was ongoing. The Legion was sent from the north to reinforce a broken line. There were repeated raids by bombers and by fighters based in Salamanca on Republican armoured vehicles and, later, defensive positions. Despite Nationalist fears, Republican aircraft were ineffective compared with German aircraft; the Messerschmitt Bf 109 was superior to the I-15 and I-16 models used by Republican forces. The Legion lost eight aircraft, but claimed 18 victories. German tactics improved after Brunete, particularly the en masse use of tanks by the Nationalists.
The Nationalists again focused on capturing northern Spain. The latest models of German test aircraft faced an outdated Basque air force which had some Soviet planes. Heavy aerial bombardment by 200 Nationalist, German, and Italian planes occurred far behind Basque lines in August 1937 and led to the fall of Santander after 1 September. The battle in Asturias ended with the fall of Gijón on 21 October. The Legion used a large amount of ammunition, including a million machine gun rounds and 2,500 tonnes of bombs.
Germany immediately began to ship its industrial production back to Spain. Sperrle argued repeatedly with Faupel against HISMA's monopoly, and Franco demanded Faupel's replacement. Sperrle also returned to Germany, and was replaced by Hellmuth Volkmann. After disagreements with Volkmann, Von Richthofen was replaced with Hermann Plocher in early 1938.

After the next major campaigns (Madrid and Barcelona), the Condor Legion was moved to Soria and began a week of strikes against Republican airfields. This move was halted by the Republican advance on Teruel. The Legion's land and air forces were deployed in Bronchales. Poor weather resulted in few flights, and the town fell to Republican forces on 6 January.
Up to 100 sorties a day were launched during the Nationalist's counter-offensive through the Alfambra Valley. The Junkers Ju 87A was used for the first time in the advance on Teruel, which was retaken on 22 February. The continued Nationalist offensive in Aragon from April to June 1937, including the Battle of Belchite, involved bombing raids and the Legion's ground forces.
The Legion was switched to focus in the north, towards the Segre River, before moving south again after Nationalist successes. It moved its headquarters to Benicarló; single-engine planes operated from nearby airfields, and twin-engine planes from Zaragoza.
Hitler's words to his colleagues belied a change in attitude about the war in Germany; a quick victory was undesirable, and a continuation of the war would be preferable. German policy was to prevent a Republican defeat. Casualties were beginning to mount for the Legion and – combined with a resurgence in Republican air activity – the Nationalist advance stalled, perhaps because of the reluctance of German commanders to supply reinforcements in light of the emerging Czechoslovak crisis. Debates about the operation's rising cost to the Germans — then about 10 million Reichsmarks a month — continued unresolved. The Legion's materiel was exhausted.
Republican forces launched their last major offensive of the war, the Battle of the Ebro (24–25 July). Condor Legion reconnaissance units had noticed a troop build-up and warned Nationalist forces, but their warning went unheeded. Although the Republicans gained ground, they failed to gain control of Gandesa; 422 sorties by the Legion (with around 70 aircraft operational) had a considerable effect. The rest of the battle saw a series of artillery attacks or air strikes, followed by a Nationalist ground advance.
Tensions in Czechoslovakia and a pilot shortage in Germany led to the return of 250 aircrew from the Legion, about half of whom were bomber crew. Although trained Spaniards made up some of the shortfall, Volkmann complained to central command in Berlin and was recalled in September. During the 113-day battle, 10 Legion aircraft were lost (some by accident) and 14 were badly damaged. The Legion claimed about 100 Republican aircraft, one-third of those lost; five aircrew were killed, and six captured. Aid from Germany temporarily halted in mid-September. Germany and Nationalist Spain settled the issue of German interests in Spanish mines.
The Legion took a short break from active duty to receive new aircraft (including Bf 109Es, He 111Es and Js, and Hs 126As), which brought its strength to 96 aircraft — about one-fifth of the Nationalist force. Richthofen returned to Spain in overall command, with Hans Seidemann as chief of staff. That reinforcement may have been the most important intervention by a foreign side in the war, enabling a counterattack after the Battle of the Ebro. The Legion primarily took part in operations against the remaining Republican air force in January and February 1939, with considerable success.
The war ended in 1 April 1939. The Legion participated in victory parades in Barcelona and elsewhere, performed minor duties over Madrid, and then was disbanded. On 26 May, the men departed for Germany. The best aircraft were also returned to Germany, and the rest of the equipment was bought by the new Spanish regime.
The Condor Legion claimed to have destroyed 320 Republican planes with aircraft (shot down or bombed on the ground) and to have shot down another 52 with anti-aircraft guns. It claimed to have destroyed 60 ships, including Spanish Republican Navy vessels. The Legion lost 72 aircraft from hostile action, and another 160 from accidents.
Maritime operations
The Maritime Reconnaissance Staffel 88 (German: Aufklärungsstaffel See 88) was the Condor Legion's maritime unit under the command of Karl Heinz Wolff. Operating independently of the land-based division, it acted against enemy shipping, ports, coastal communications and occasionally inland targets such as bridges. It used floatplanes, starting with the Heinkel He 60, which began operating at Cádiz in October 1936. Missions started as reconnaissance, but after the move from Cádiz to Melilla in Spanish Morocco in December 1936, the focus shifted to attacks on shipping. It was again moved in February 1937 to Málaga, which was newly captured, and then to Mallorca when Málaga proved unsuitable. In June, operations began to be expanded to allow attacks on all Republican ports as long as British ships were not present. There were 10 ships attacked in the second half of 1937, but the Norwegian torpedoes that were used proved ineffective, and strafing or bombing targets was used instead.
The arrival of Martin Harlinghausen (known as "Iron Gustav") saw operations expand, and operations targeted Alicante, Almería, Barcelona and Cartagena. As naval activity declined, inland targets became more numerous, and night missions began. Activities in support of ground forces became the main focus of the unit until the end of hostilities. Both Wolff and Harlinghausen received the Spanish Cross in Gold with Swords and Diamonds. In total, eleven men were killed in action, and five others died due to accident or illness.
Other operations
Overtly, the Kriegsmarine was partly used to enforce the Non-Intervention Agreement from interfering in the war. However, the agreement was clearly broken by Germany. As a result, the German pocket battleship Deutschland stood guard over Ceuta to prevent interference from Republican ships while Franco transported troops to the Spanish mainland. By mid-October, the German North Sea Group around Spain consisted of the pocket battleships Deutschland and Admiral Scheer, the light cruiser Köln, and four torpedo boats. After the Germans claimed that Leipzig had been attacked by an unidentified submarine, it was formally withdrawn from international patrols.
Operation Ursula, named after the daughter of Karl Dönitz, involved a group of German U-boats active around Spain. It began on 20 November 1936, with the movement of the U-33 and the U-34 from Wilhelmshaven. Identification marks were obscured, and the whole mission was kept secret. Difficulties in identifying legitimate targets and concerns about discovery limited their operations. During their return to Wilhelmshaven in December, the Republican submarine C-3 was sunk; the Germans claimed that the sinking resulted a torpedo fired by U-34, although the Republican enquiry claimed its loss to have been caused by an internal explosion. Their submarines' return marked the official end of Operation Ursula. However, further submarines seem to have been sent in mid-1937, but details of the operation are not known (although six are believed to have been involved).
Abwehr
The German Abwehr intelligence service, independent of the Condor Legion, was secretly involved in Operation Bodden and later played a part in the detection of the Operation Torch invasion fleet.
Return to Germany
The KdF fleet, including the MV Wilhelm Gustloff and seven other ships, were given secret orders on 20 May 1939 and diverted from their regular pleasure-cruise schedule to arrive in Vigo, Spain. They arrived on 24 May to pick up the legion, and departed on 26 May for a five-day voyage to Hamburg, Germany. They arrived to crowds, parades and ceremonies celebrating their success, with Hermann Göring and other high-ranking officials in attendance.
Military gains
Training

Many army leaders were hesitant to become involved in the conflict, and resisted a call from the Italian government for a transfer of ground troops to Spain. Luftwaffe involvement was not restricted, and it is commonly thought that its involvement in the Spanish Civil War was a proving ground for troops in World War II. That view is supported by the testimony of Hermann Göring when he was on trial in Nuremberg. Asked about the decision to use the Luftwaffe, Göring said:
When the Civil War broke out in Spain, Franco sent a call for help to Germany and asked for support, particularly in the air. One should not forget that Franco with his troops was stationed in Africa and that he could not get the troops across, as the fleet was in the hands of the Communists, or, as they called themselves at the time, the competent Revolutionary Government in Spain. The decisive factor was, first of all, to get his troops over to Spain. The Führer thought the matter over. I urged him to give support [to Franco] under all circumstances, firstly, in order to prevent the further spread of communism in that theater and, secondly, to test my young Luftwaffe at this opportunity in this or that technical respect.
It was cited in Western media after German forces left Spain.
Dozens of Messerschmitt Bf 109 fighters, Heinkel He 111 medium bombers and, after December 1937, at least three Junkers Ju 87 Stuka dive bombers first saw active service in the Condor Legion against Soviet aircraft. The Stuka's first mission in Spain was in February 1938, and each aircraft played a major role early in World War II. The Germans realised that biplane fighters were quickly becoming less effective than newer monoplane designs. The Heinkel He 51 fighter, after many losses during the first twelve months of the war, was switched to a ground-attack role and later saw service as a trainer.
Other units
The Condor Legion included ground-combat units. Panzer crews operating Panzer I light tanks were commanded by Wilhelm Ritter von Thoma. The Germans also tested small numbers of 88 mm Flak 18 anti-aircraft artillery guns to destroy Republican tanks, fortifications and aircraft with direct fire. German involvement in Spain spurred development of the first air ambulance service for evacuation of wounded combatants.
Technical advances
A Condor Legion Bf 109 C-1, Jagdgruppe 88
One military innovation thought to have resulted from the conflict is the technical development of the Messerschmitt Bf 109. The V3 to V6 types entered service in Spain from operational trials around January 1937. They were joined by type C aircraft in spring 1938, with type Es first deployed in December of that year.
Tactics
In addition to combat experience, it is thought that strategic initiatives were first tested during Luftwaffe involvement in the Spanish Civil War. Legion commander in Spain Wolfram von Richthofen became a Field Marshal during World War II and served in high Luftwaffe positions, specialising in ground attacks. His units spearheaded offensives in Poland, France and the Low Countries and the Balkans, and in Operation Barbarossa.
Joint operations were emphasised. Close air support for Nationalist troops, attack bombing of Republican troop concentrations, and strafing were features of the war. The legion worked to maximise the fighting ability of the Nationalist air force and troops, the Italian CTV, and pilots from the Aviazione Legionaria (Legionary Air Force). German air ace Adolf Galland said that in focusing after World War II on lessons learned by the Germans from the conflict in Spain, the value of the lessons was exaggerated. Galland believed that the wrong conclusions were drawn by the German High Command, particularly regarding the Luftwaffe:
Whatever may have been the importance of the tests of German arms in the Spanish Civil War from tactical, technical and operational points of view, they did not provide the experience that was needed nor lead to the formulation of sound strategic concepts.
Commemoration and re-evaluation
Condor Legion

Shame about the activities of the Condor Legion and its involvement in the bombing of Guernica have re-surfaced in Germany since its 1990s reunification. In 1997, the 60th anniversary of Operation Rügen, German President Roman Herzog wrote an apology on behalf of the German people and state to survivors of the raid. Herzog said that he wanted to extend "a hand of friendship and reconciliation" on behalf of all German citizens. The sentiment was echoed by members of the German Parliament who, in 1998, legislated the removal of all former Legion members' names from German military bases. The issue surfaced again in 2005 after media reports about the role of pilot Werner Mölders, who had volunteered to serve in Spain. Although he was not involved in the bombing of Guernica, it was decided by German Defence Minister Peter Struck that Mölders' name would be removed from the barracks at Visselhoevede and from association with Luftwaffe Fighter Wing 74 (Jagdgeschwader 74) based in Neuburg an der Donau. Until then, it had not been established that Mölders had flown as a Condor Legion volunteer before his death in 1941.
On 26 April 2017, the 80th anniversary of the Guernica bombing, the Madrid City Council announced that it had dismantled the Condor Legion mausoleum at the Cementerio de la Almudena, which had been built in early 1942. The mausoleum's facade, removed at the request of the German embassy in Madrid, would be replaced with name plaques for the seven soldiers entombed there.
Awards
Condor Legion
The Spanish Cross (German: Spanienkreuz) campaign medal began to be awarded by the German authorities in seven classes on 14 April 1939. The clandestine nature of German activities in Spain meant that no awards were made until April 1939, at the end of German involvement in the conflict. The Spanish Cross complemented the Condor Legion Tank Badge, which was approved on 10 July 1939, and cuff titles were issued. Legionnaires also received a campaign medal struck by the Spanish authorities to thank German volunteers for their service. An al Merito En Campaña medal was awarded to the legion as a whole, and added to its battle flag.
The legion assembled for an address by Hitler on 6 June 1939 and for a parade as part of the 20 April 1939 celebrations of Hitler's 50th birthday. Its activities were commemorated in a special issue of Der Adler, the Luftwaffe's propaganda magazine, which was circulated in Spain and the United States.
