June 18, 2026, marks the 86th anniversary of General de Gaulle's appeal broadcast from London on the BBC. On June 18, 1940, as France suffered a military defeat and Marshal Pétain's government was preparing for an armistice, a then little-known general refused to accept defeat as final. From the British capital, where he had arrived the day before, de Gaulle called upon French citizens capable of continuing the fight to join him. This address, which went largely unheard at the time, later became the founding act of Free France and one of the major landmarks of French national history.
France is in complete collapse
On June 18, 1940, France was in a state of collapse. Since May 10, the German army had launched its offensive in the West. The German strategy relied on speed, armored vehicles, air power, and breaking through the front lines. The breakthrough at Sedan had disorganized the French defenses. The Allied armies were cut in two. Some British and French troops were evacuated via Dunkirk, but the Battle of France was lost.
On June 14, German troops entered Paris. The capital was declared an open city. The French government retreated to Bordeaux. Millions of civilians were on the roads of the exodus. Political authority faltered as the army withdrew.
On June 16, Paul Reynaud resigned as President of the Council. Marshal Philippe Pétain succeeded him. The following day, June 17, Pétain addressed the French people on the radio and announced that he had requested terms for an armistice from Germany. His message signified the imminent end of hostilities on behalf of the French government.
At that precise moment, Charles de Gaulle rejected this direction.
De Gaulle, a general still little known
Charles de Gaulle is not yet the man for which national memory will be remembered. In June 1940, he was a temporary brigadier general. A career officer and veteran of the First World War, he had advocated before the war for a modern, mobile army supported by tanks and aircraft. His ideas were long marginalized.
During the Battle of France, he commanded the 4th Armored Division and led counter-attacks, notably in the Aisne and then the Somme. On June 6, 1940, Paul Reynaud appointed him Under-Secretary of State for War and National Defense. De Gaulle then participated in the final discussions on the possible continuation of the fight, particularly from the French colonial empire and with British support.
On June 16, he returned from a mission to London. In Bordeaux, he learned of Reynaud's resignation and Pétain's rise to power. For him, the request for an armistice committed France to a political as well as a military defeat. He decided to return to England immediately.
Departure for London
On June 17, 1940, de Gaulle left France. He departed for London with his aide-de-camp, Lieutenant Geoffroy Chodron de Courcel. His departure was far from an official installation. He had neither a government, nor a formed army, nor his own administration. He arrived in a British capital still engaged in the war, at a time when the United Kingdom found itself practically alone against Nazi Germany in Western Europe.
In London, de Gaulle temporarily settled. His first priority was to find a way to communicate with the French people. Radio proved to be the decisive tool. From the BBC, a voice could cross the Channel and reach the mainland, despite the defeat, the exodus, and the looming censorship.
The possibility of speaking on the BBC depended on the British. Winston Churchill agreed to grant him airtime. London, however, wanted to maintain a delicate diplomatic situation: the Pétain government had just requested an armistice, but the German conditions were not yet known. The British did not want to sever all ties with the French authorities just yet.
De Gaulle's text is therefore concise. It is not yet a full proclamation of power. He does not call upon the entire French people for an immediate insurrection. He addresses himself primarily to the military, officers, soldiers, engineers, and skilled armament workers likely to join the British forces or contribute to the continuation of the war.
In the BBC studios
On June 18, de Gaulle went to the BBC. He spoke on the British radio station's French program, Radio London. Accounts and historical works do not all give the exact same broadcast time. Official sources generally cite an evening broadcast, often around 18 p.m. or 20 p.m., depending on the account.
The setting is simple: a studio, a microphone, a general virtually unknown to the French public. De Gaulle has not yet established himself as the leader of Free France. The Cross of Lorraine has not yet become the emblem of the movement. The photographs often used to illustrate the appeal are not from June 18, 1940, but from later periods.
That evening, de Gaulle directly responded to Pétain's speech from the previous day. He reiterated the military analysis of the defeat: France had been overwhelmed by German mechanized force, by tanks, aircraft, and tactics. He then challenged the notion that this defeat determined the outcome of the war.
His reasoning rests on three points. France still possesses its Empire. The United Kingdom continues the fight and dominates the seas. The United States possesses immense industrial power. The Battle of France is lost, but the war extends beyond French territory. It is a global war.
A military call before it became a national myth
The Appeal of June 18th was not widely heard live. A large part of the French population was on the roads, without radios, without access to the BBC, or without even knowing de Gaulle's name. The French press only partially reported his words. Some newspapers even misspelled his name.
Its significance stems from its date, its content, and its break with the official line of the French government. On June 18, de Gaulle asserted that there was another path besides the armistice: continuing the war alongside the United Kingdom. He laid the foundations for a new legitimacy, external to Vichy, based on the continuation of the fight.
It still lacked any significant force. Initial support was weak. A few soldiers, sailors, airmen, civilians, and volunteers joined London. Gradually, territories of the Empire rallied to Free France. French Equatorial Africa played a major role from the summer of 1940 onward, particularly with the rallying of Chad, Cameroon, Congo, and Ubangi-Shari.
On June 27, Churchill recognized de Gaulle as leader of the Free French. This British recognition provided a political and military framework for his actions.
What the call didn't say
For a long time, memory confused several Gaullist texts from June and July 1940. The famous formula "France has lost a battle! But France has not lost the war!" It does not come from the radio broadcast of June 18th. It belongs to the poster "To all French people", written and later posted in London.
The speech of June 18th was shorter, more focused, and more military in tone. In it, de Gaulle invited French citizens present in British territory, or likely to arrive there, to contact him. He addressed soldiers, officers, engineers, and munitions workers. He concluded with the idea that the French resistance must continue.
The official text is not necessarily word for word the one spoken on the air. No original recording allows us to verify the intonation, the exact cuts, or the final wording. Historians have manuscripts, published versions, transcriptions, recollections, and later texts at their disposal. This is enough to establish the historical meaning of the appeal, but not enough to reconstruct every second of the broadcast with absolute certainty.
The soundtrack: what we hear today
No audio recording of the Appeal of June 18, 1940, has survived. The BBC did not keep the tape. The appeal sometimes heard during commemorations is therefore not the original recording of June 18.
The confusion stems primarily from the speech of June 22, 1940. On that day, de Gaulle spoke again on the BBC after the signing of the Franco-German armistice at Rethondes. This June 22 address, however, has been preserved. His actual voice can be heard in it. Because it reiterates the themes of June 18 and belongs to the same pivotal days, it is often confused with the initial appeal.
Since 2023, a sound reconstruction created using artificial intelligence technology has also been available. This reconstruction aims to give an idea of what listeners might have heard in 1940. It is not an archival document. It does not replace the original recording, which does not exist.
June 22nd: the armistice and the final break
On June 22, 1940, the Franco-German armistice was signed at Rethondes, in the clearing of Compiègne. Hitler chose this location to impose a symbolic humiliation on France, in the railway carriage where the 1918 armistice had been signed.
The conditions were harsh. Metropolitan France was divided by a demarcation line. The north and west fell under German occupation. The south remained under the authority of the French government in Vichy. The French army was reduced in size. Prisoners of war remained in captivity. The occupying power imposed its rights over the occupied zone. The armistice came into effect on June 25, following the signing of the Franco-Italian armistice.
De Gaulle rejected this logic. In London, he built an organization that took the name Free France. The Vichy regime considered him a dissident. He was sentenced in absentia. For the volunteers who joined him, he became the rallying point of a France that refused to withdraw from the war.
From London to Free France
The first few months were difficult. De Gaulle had to convince the British, attract volunteers, secure military resources, rally territories, and assert his authority over other French figures. Free France was born in a state of great material weakness, but with a simple idea: France would remain committed to the war as long as Frenchmen fought in its name.
The Free French Forces gradually joined the Allied operations. They fought in Africa, the Levant, the Atlantic, and then on several fronts. At the same time, in mainland France, networks and movements of the internal Resistance were forming. They were not all initially Gaullist. Some came from military, socialist, communist, Christian democratic, trade unionist, or patriotic backgrounds without any political affiliation.
From 1942 and 1943, de Gaulle sought to unite these forces. Jean Moulin played a decisive role in the unification of the internal Resistance. In May 1943, the creation of the National Council of the Resistance gave a political structure to the clandestine struggle. Free France and the internal Resistance gradually merged into Fighting France.
A date that has become pivotal
June 18th quickly became a date of remembrance. As early as 1941, de Gaulle commemorated the anniversary of his first appeal. After the Liberation, this date took on a central place in the national narrative of the Second World War. It represents the continuity of the French struggle despite the armistice, the occupation, and collaboration.
On June 6, 1944, the Allies landed in Normandy. The Free French Forces and the French Resistance participated in the liberation of the territory. On August 25, 1944, Paris was liberated. De Gaulle then established himself as the head of the Provisional Government of the French Republic. Vichy was dismissed as an illegitimate regime born of defeat.
June 18, 1940, remains the first public manifestation of this political stance. In the midst of the debacle, de Gaulle asserted that the war did not end with the French military defeat. He viewed the conflict on a global scale, understood the decisive role of the industrial powers, and placed France on the side of the Allies, even though his official government opted for an armistice.
