When World War II broke out in September 1939, the French and British governments immediately sought to persuade Belgium to join them. Leopold and his government refused, maintaining Belgium's neutrality. Belgium considered itself well-prepared against a possible invasion by
Axis forces, for during the 1930s the Belgian government had made extensive preparations to deter and repel an invasion of the country by Germany such as the one that had occurred in 1914. On 10 May 1940, the
Wehrmacht invaded Belgium. On the first day of the offensive, the principal Belgian strong point of
Fort Eben-Emael was overwhelmed by a daring paratroop operation and the defensive perimeter thus penetrated before any French or British troops could arrive. After a short running battle that eventually involved the armies of all four belligerents, Belgium was overwhelmed by the numerically superior and better-prepared Germans. Nevertheless, the Belgian perseverance prevented the
British Expeditionary Force from being outflanked and cut off from the coast, enabling the
evacuation from Dunkirk.
Alan Brooke who commanded II Corps of the BEF thought that the 10th Belgian Division was in the wrong place and wanted to deploy north of Brussels to avoid "double-banking". He was advised by
Roger Keyes to see the king, as the king was commanding the Belgian forces, and on 12 May was "making progress in getting matters put right" in discussion with the king in English, but was interrupted (twice) by the king's advisor who spoke to the king in French (in which Brooke was fluent). The advisor was insistent that the Belgian division could not be moved and the BEF should be stopped further south and clear of Brussels; Brooke said he was not putting the whole case to the king; he found that arguing with the advisor was a sheer waste of time as he cared little about the BEF and most of his suggestions were "fantastic". The king's advisor
Raoul Van Overstraeten was not the Chief of Staff, as Brooke had assumed - Van Overstraeten had refused that rank - but the king's
aide-de-camp, with the rank of Major-General, and would not give up the Louvain front. The French liaison officer, General Champon, told Brooke that Van Overstraeten had ascendancy over the king and had taken control, so it was useless to see the Chief of Staff. Later (15 May) Brooke found that the BEF was likely to "have both flanks turned" with French defeats, and started withdrawal on 16 May. After his military surrender, Leopold (unlike
Queen Wilhelmina of the Netherlands in a similar predicament) remained in Brussels to surrender to the victorious invaders, while his entire civil government fled to Paris and later to London.
Surrender and constitutional crisis On 24 May 1940, Leopold, having assumed command of the
Belgian Army, met with his ministers for the final time. The ministers urged the king to leave the country with the government. Prime Minister
Hubert Pierlot reminded him that capitulation was a decision for the Belgian government, not for the king, to make. The king indicated that he had decided to remain in Belgium with his troops, whatever the outcome. The ministers took this to mean that he would establish a new government under the direction of Hitler, potentially a treasonous act. Leopold thought that he might be seen as a deserter if he were to leave the country: "He was resolved to remain with his army and amidst his people so as to share their fate." Leopold had long had a difficult and contentious relationship with his ministers, acting independently of government influence whenever possible, and seeking to circumvent and even limit the ministers' powers, while expanding his own. French, British, and Belgian troops were encircled by German forces at the
Battle of Dunkirk. Leopold notified King
George VI by telegram on 25 May 1940 that Belgian forces were being crushed, saying "assistance which we give to the Allies will come to an end if our army is surrounded". Two days later (27 May 1940), Leopold surrendered the Belgian forces to the Germans. Prime Minister Pierlot spoke on French radio, saying that the king's decision to surrender went against the
Belgian Constitution. The decision, he said, was not only a military decision but also a political decision, and the king had acted without his ministers' advice, and therefore contrary to the Constitution. Pierlot and his government believed this created an
impossibilité de régner: It was impossible, however, to summon the Belgian
Chamber of Representatives or Belgian
Senate at this time, or to appoint a
regent. After the liberation of Belgium in September 1944, the government asked Leopold's brother,
Prince Charles, to serve as regent. After Leopold's surrender, the British press denounced him as "Traitor King" and "King Rat"; the
Daily Mirror published a picture of Leopold with the headline "The Face That Every Woman Now Despises". A group of Belgian refugees in Paris placed a message at
King Albert's statue denouncing his son as "your unworthy successor". French Prime Minister
Paul Reynaud accused Leopold of treason. Flemish historians Valaers and Van Goethem wrote that Leopold III had become "The scapegoat of Reynaud", because Reynaud was probably already aware that the
Battle of France was lost. Leopold's surrender was also decried by Winston Churchill. In the
House of Commons on 4 June 1940 he said: At the last moment when Belgium was already invaded, King Leopold called upon us to come to his aid, and even at the last moment we came. He and his brave, efficient army, nearly half a million strong, guarded our left flank and thus kept open our only line of retreat to the sea. Suddenly, without prior consultation, with the least possible notice, without the advice of his ministers and upon his own personal act, he sent a plenipotentiary to the German Command, surrendered his army and exposed our whole flank and means of retreat. In 1949, Churchill's comments about the events of May 1940 were published in
Le Soir (12 February 1949). Leopold's former secretary sent a letter to Churchill saying that Churchill was wrong. Churchill sent a copy of this letter to the King's brother,
Prince Charles, via his secretary André de Staercke. In his own letter Churchill wrote, With regards to King Leopold, the words which I used at the time in the House of Commons are upon record and after careful consideration I do not see any reason to change them (...) it seemed to me and many others that the king should have been guided by the advice of his ministers and should not have favoured a course which identified the capitulation of the Belgian Army with the submission of the Belgian State to Herr Hitler and consequently taking them out of the war. Happily this evil was averted, and in the end, all came right. I need scarcely say that nothing I said at the time could be interpreted as a reflection upon the personal courage or honour of King Leopold. De Staercke replied that Churchill was right: "The Prince, Monsieur Spaak [Belgian Foreign Minister
Paul-Henri Spaak] and I read your text, which states the precise truth and seems perfect to us." Belgian historian Francis Balace wrote that capitulation was inevitable because the Belgian Army was not able to fight any longer against the German army. Even Churchill admitted that their position was perilous. In a telegram to
Field Marshal Lord Gort on 27 May, only one day before the Belgian capitulation, he wrote, "We are asking them to sacrifice themselves for us."
After the fall of France Upon Leopold's surrender, the government ministers left for exile, mostly in France. When France fell at the end of June 1940, several ministers sought to return to Belgium. They made an overture to Leopold but were rebuffed. Because of the great popularity of the king, and the unpopularity of the civil government from the middle of 1940, the government crisis persisted. On 2 August 1940, several ministers conferred in
Le Perthus in France near the Spanish border. Prime Minister Pierlot and Foreign Minister Spaak were persuaded to go to London, but they were able to start out for London only at the end of August and could travel only via neutral Spain and Portugal. When they reached Spain, they were arrested and detained by the regime of
Francisco Franco; they finally arrived in London on 22 October.
Meeting with Hitler Leopold rejected cooperation with the
government of Nazi Germany and refused to administer Belgium in accordance with its dictates; thus, the Germans implemented a military government. Leopold attempted to assert his authority as monarch and head of the Belgian government, although he was a prisoner of the Germans. Despite his defiance of the Germans, the Belgian government-in-exile in London maintained that the king did not represent the Belgian government and was unable to reign. The Germans held him at first under
house arrest at the
Royal Castle of Laeken. Having since June 1940 desired a meeting with Adolf Hitler in respect of the situation of Belgian prisoners of war, Leopold III finally met with him on 19 November 1940. Leopold wanted to persuade Hitler to release Belgian POWs, and issue a public statement about Belgium's future independence. Hitler refused to speak about the independence of Belgium or issue a statement about it. In refusing to publish a statement, Hitler preserved the king from being seen as cooperating with Germany, and thus engaged in treasonous acts, which would likely have obliged him to abdicate upon the liberation of Belgium. "The [German] Chancellor saved the king two times."
Second marriage On 11 September 1941, while a prisoner of the Germans, Leopold secretly married
Lilian Baels in a religious ceremony that had no validity under Belgian law, which required a religious marriage to be preceded by a legal or
civil marriage. On 6 December, they were married under
civil law. The reason for the out-of-order marriages was never officially made public.
Jozef-Ernest Cardinal van Roey,
Archbishop of Mechelen, wrote an open letter to parish priests throughout the country announcing Leopold's second marriage on 7 December. The letter from the Cardinal revealed that the king's new wife would be known as Princesse de Réthy, not Queen Lilian, and that any children
they had would have no claim to the throne. Leopold's new marriage damaged his reputation further in the eyes of many of his subjects.
The Political Testament . The ministers made several efforts during the war to work out a suitable agreement with Leopold III. They sent Pierlot's son-in-law as an emissary to Leopold in January 1944, carrying a letter offering reconciliation from the Belgian government-in-exile. The letter never reached its destination, however, as the son-in-law was killed by the Germans en route. The ministers did not know what happened either to the message or the messenger and assumed that Leopold was ignoring them. Leopold wrote his
Political Testament in January 1944, shortly after this failed attempt at reconciliation. The testament was to be published in case he was not in Belgium when Allied forces arrived. The testament, which had an imperious and negative tone, considered the potential Allied movement into Belgium an "occupation", not a "liberation". It gave no credit to the active
Belgian resistance. The Belgian government-in-exile in London did not like Leopold's demand that the government ministers involved in the 1940 crisis be dismissed. The Allies did not like Leopold's repudiation of the treaties concluded by the Belgian government-in-exile in London. The United States was particularly concerned about the economic treaty it had reached with the government-in-exile that enabled it to obtain
Congolese uranium for America's secret
atom bomb program, which had been developed for use against Germany (although, as it turned out, Germany surrendered before the first bomb was ready). The Belgian government did not publish the
Political Testament and tried to ignore it, partly for fear of increased support for the
Belgian Communist Party. When Pierlot and Spaak learned of its contents in September 1944, they were astonished and felt deceived by the king. According to André de Staercke, they were dismayed "in the face of so much blindness and unawareness". Churchill's reaction to the Testament was simply, "It stinks." In a sentence inspired by a quote of
Talleyrand about the
Bourbons after the restoration of the French monarchy in 1815, Churchill declared, "He is like the Bourbons, he has learned nothing and forgotten nothing." ==Exile and abdication==
