Winston Churchill became Prime Minister in May 1940. Soon after, Sir Samuel Hoare arrived in Madrid as the new British Ambassador to Spain. His primary mission was to secure Spanish neutrality in World War II.

UK Policy towards Spain - Non-Belligerence 1940-1942
In the early years of World War II, Britain used economic incentives, diplomatic connections, and bribery to influence Spanish officials and achieve their goals of keeping Spain neutral.

Securing Spanish Neutrality
Another key suggestion from Beigbeder involved using Spain's limited oil reserves as leverage. He urged Britain to utilize oil supplies as an economic weapon to influence Spain's position. This tactic, combined with Spain's limited options, led to negotiations with Britain and the US. The Anglo-Spanish Oil Agreement, signed on September 7, 1940, reflected the outcome of these discussions.
Throughout 1941, Britain continued to manage its diplomatic and economic ties with Spain. A new Supplementary Loan Agreement on April 7th provided Spain with additional import credits, further solidifying the relationship.
Britain's Economic Policy
Historians like Thomas Hamilton argue that a more hardline approach would have benefitted democracies. Hamilton suggests Britain should have demanded the removal of the Falange party as a condition for any agreement with Spain.
This view is echoed in contemporary sources. Sir Samuel Hoare, the British ambassador to Spain, faced criticism for his perceived appeasement of Franco's regime. He clarified his position, stating his primary goal was to keep Spain out of the Axis camp. This sentiment was particularly strong among those who had supported the Republican side in the Spanish Civil War. In a letter to the Foreign Office Hoare says, '...I do wish that you would keep ... people quiet when they harp upon the mistake that we made in not sending help to the Reds in the Civil War.'
Concerns existed regarding materials supplied to Spain potentially reaching Germany. Britain countered by providing only enough for basic consumption, preventing stockpiling. However, Spain's neutrality was questioned by Charles Burdick, who pointed to German submarines stationed in Spanish ports as evidence of their non-neutral stance. However, Hoare argued it was crucial for Spain to maintain a facade of hostility towards Britain.
Opposition arose to maintaining cordial relations with a fascist-leaning regime sympathetic to the enemy. Hoare emphasized that British policy did not signify approval of Franco or his methods, but rather aimed to keep Spain out of the war. MP David Eccles concurred, Spain's pro-Axis sympathies were acknowledged, but economic necessity trumped ideology. He later remarked on the importance of the protracted economic negotiations.
The effectiveness of this strategy was even recognized by Adolf Hitler. His Operation Felix, designed to capture Gibraltar with Franco's help, was reportedly delayed due to British promises of food supplies. This exemplifies Britain's use of economic warfare to achieve its goals.
Following the war, Hoare reflected on the success of Britain's economic policy in Spain. He credited it with opening previously closed political doors: "armed with our economic programme, we were first able to bring the Embassy into close friendly and personal contact with an important Spanish Department of State." This highlights the significance of economic policy in establishing commercial and later, political relations with Spain.
The Mediterranean in World War II
British officials, including Sir Samuel Hoare, explored options to foster better relations with Spain. One strategy involved significant financial incentives for high-ranking Spanish generals. While specific names have not been publicly revealed, documents show a $14 million deposit in the Swiss Bank Corporations in New York. This sum was to be distributed by businessman Juan March to influential Spanish Generals.
Juan March: A Controversial Figure
March's involvement with British intelligence was not new. He funded Franco's flight to Morocco, sparking the Spanish Civil War. He also had a history of playing "el doble juego" (the double game), potentially offering services to both Britain and Germany during World War I. Captain Alan Hillgarth, the British naval attache in Madrid, emphasized the need for caution, stating "It would be a mistake to trust him an inch."
Deaspite Hillgarth's reservations, a £2 million transfer from the Bank of England to "nuestro amigo" ("our friend") March suggests a deal was struck. Even Prime Minister Churchill recognized March's potential to influence Spanish neutrality.
A Delicate Operation
Despite the concerns, the operation's importance outweighed the risks. Foreign Office documents detail the challenges encountered, including the Swiss Bank Corporations freezing the funds due to suspicious activity. Unblocking the funds became crucial for British objectives, as highlighted by Sir Samuel Hoare.
The solution involved a personal request from the Prime Minister to President Roosevelt. Roosevelt agreed to release the funds without informing the US Treasury or the Swiss bank, citing "political services" rendered by unnamed individuals. Hoare confirmed the successful resolution of the entire transaction on December 6th, 1941.
Payne downplays the impact of the bribery, but evidence suggests otherwise. Within a week of the initial payment, Hoare reported progress with the dismissal of pro-Axis General Juan Yague. Further confirmation came in October with a secret letter from Hoare detailing the bribing of six influential Generals, advisors to Franco, using a hidden "secret fund." This message emphasized the scheme's effectiveness: "I send you personally these further details...so that you may know the money is not being used in vain."
The most dramatic outcome occurred in May 1941. General Juan Vigon, believed to be a recipient of British funds, threatened Franco with mass resignations from his military advisors if he did not limit the power of Ramon Serrano Suner. Suner, replacing the pro-British Beigbeder as Foreign Minister, was seen as a setback due to his pro-Axis leanings. Franco's subsequent cabinet reshuffle strongly suggested the bribes' success. Appointments of Suner's critics, Luis Orgaz and Alfredo Kindelan, to key positions, along with a new anti-Falange Interior Minister, signaled Suner's diminished influence. Minister of Economic Warfare Hugh Dalton observed: "the Knights of St George have charged: it is thanks to them that certain recent changes have been brought about," referencing the British codename for the bribery operation. Similarly, Hoare informed the Foreign Office: "No doubt you have realised that the political changes here are directly due to the secret plan..."

Britain's Secret Plans for a "Free Spain Movement"
Britain pledged support to figures like Pedro Sainz Rodriguez and General Aranda. The plan involved transporting them to the Canary Islands to establish a rival Spanish government in exile if Germany invaded. Spanish diplomat Francois Beigbeder encouraged the possibility of Spanish resistance, highlighting the importance of covert operations alongside official diplomacy.
While Britain publicly maintained a hands-off approach to Spanish internal affairs, internal documents acknowledge the potential benefits of connections with opposition elements, particularly monarchists. Social unrest and failed government reforms had led to King Alfonso XIII's abdication in 1931. Growing resentment towards the Falange party and Franco's alignment with the Axis powers fuelled a desire among many Spaniards to overthrow Franco and restore the monarchy.
British Foreign Secretary Samuel Hoare expressed his views to Prime Minister Winston Churchill, believing a "monarchist restoration would be just the kind of explosion that is needed." Dispatches from Hoare and Foreign Secretary Anthony Eden shed light on Britain's position regarding a potential monarchist revival. The documents state that "in the event of an invasion of Spain by the Germans or of the Spanish Government throwing in their lot with the enemy, it would be in our interests that a Free Spanish Movement should be formed, capable and willing to continue the fight from overseas."
Britain saw an opportunity to capitalize on the growing monarchist sentiment, especially after King Alfonso's death. Additionally, the heir to the throne, Infante Don Juan, was seen as potentially favourable due to the political leanings of his British-born mother, Queen Victoria Eugenie, a known supporter of the Allied cause.
While a monarchist restoration under a pro-British regime was desirable, the documents acknowledge that "an immediate movement is ... unlikely as responsible leaders are all waiting to see how the war is going on." Britain's planning for this contingency demonstrates their willingness to explore all options to achieve their objectives, even if it meant potentially undermining a supposedly friendly regime.
Achieving Neutrality
Operation Torch, the Allied invasion of North Africa in November 1942, marked a turning point in relations. Hoare emphasized the invasion's significance in his memoirs: "The Allies... were undertaking grave risks unless Spanish neutrality could be guaranteed." A failed landing could have triggered a German attack on North Africa, Spain, and Spanish Morocco, with or without Spanish consent. While Spain might have reacted negatively to the invasion, it demonstrably did not, despite German demands for action. Lieutenant Commander Harry Butcher, Naval Aide to General Dwight D. Eisenhower, in a diary entry from a few days after the landing confirms this: "Hitler had demanded... free passage for his forces through Spain." The US Ambassador to Spain, Carlton Hayes, corroborates this, stating that Germany made this request twice but was rejected. This highlights Spain's desire to avoid antagonizing Britain and validates the success of the preceding years' economic and diplomatic efforts. As Hoare summarized: "we might well have faced a sudden crisis in Spain. However, we had built up a valuable reserve of goodwill in the country through our economic program." Furthermore, Torch's political ramifications were substantial, as Spain's renewed vulnerability to attack from both sides effectively ended Franco's imperialist aspirations.
Franco's Neutrality: A Balancing Act or Necessity?
However, Peter Day argues that Spain's reliance on British markets was a major factor in its neutrality, especially during the Axis' peak years. He suggests the war's devastation combined with this economic dependence made joining the Axis unrealistic.
While Spain's post-war economic hardship likely played a role, Day emphasizes Britain's skilful exploitation of this situation. Britain's resourcefulness, he argues, was key. They used economic incentives, diplomatic connections (including the Foreign Minister), and even bribery to influence Spanish officials and achieve their goals of keeping Spain neutral.
