Armistice of 22 June 1940 in the context of "Antoine de Saint-Exupéry"

Army Group A (German: Heeresgruppe A) was the name of three distinct army groups of the Heer, the ground forces of the Wehrmacht, during World War II.

The first Army Group A, previously known as "Army Group South", was active from October 1939 to June 1941 and notably served in the Battle of France as the decisive army group in the implementation of the "Sickle Cut" military plan that inflicted crushing subsequent defeats on the French armed forces at occasions such as the Battle of Sedan, Battle of Boulogne and Battle of Dunkirk and that ultimately led to the Armistice of 22 June 1940. Army Group A was subsequently used in the German occupation of France and temporarily became the first Oberbefehlshaber West in German-occupied France. It was eventually replaced in this function by Army Group D and redeployed to German-occupied Poland in preparation for Operation Barbarossa. At the commencement of that attack, Army Group A was renamed "Army Group South" on 22 June 1941, ending the first deployment.

Vichy France (French: Régime de Vichy, lit. 'Vichy regime'; 10 July 1940 – 9 August 1944), officially the French State (État français), was a French rump state headed by Marshal Philippe Pétain during World War II, established as a result of Germany victory in the Battle of France. It was named after its seat of government, the city of Vichy.

Officially independent, but with half of its territory occupied under the harsh terms of the 1940 armistice with Nazi Germany, it adopted a policy of collaboration. Though Paris was nominally its capital, the government established itself in Vichy in the unoccupied "free zone" (zone libre). The occupation of France by Germany at first affected only the northern and western portions of the country. In November 1942, the Allies occupied French North Africa, and in response the Germans and Italians occupied the entirety of Metropolitan France, ending any pretence of independence by the Vichy government.

The French demarcation line was the boundary line marking the division of Metropolitan France into the territory occupied and administered by the German Army (Zone occupée) in the northern and western part of France and the Zone libre (Free zone) in the south during World War II. It was created by the Armistice of 22 June 1940 after the fall of France in May 1940.

The path of the demarcation line was specified in the Articles of the Armistice. It was also called the green line because it was marked green on the joint map produced at the Armistice Convention. In German, the line is known as the Demarkationslinie, often shortened to Dema-Linie or even Dema.

Italy entered World War II on 10 June 1940 by invading France, joining the German offensive already in progress. Italian dictator Benito Mussolini did so opportunistically as the Allied powers (chiefly France and the United Kingdom) seemed on the verge of collapse. The Italian war aim was to expand its colonial empire at the expense of the French and the British. While France surrendered on 22 June 1940, the United Kingdom and its allies continued to fight far beyond the point which Mussolini had thought possible, ultimately leading to the defeat and dissolution of Fascist Italy in 1943 when Mussolini was deposed in a bloodless coup d'état.

Italy's Axis partner, Nazi Germany, was ready for its defection and occupied central and northern Italy after the armistice of Cassibile in September 1943. After freeing Mussolini from captivity, the Germans set him up as the leader of a new puppet state in the north, the Italian Social Republic. This provoked Italian resistance against the German occupation and also a civil war between pro- and anti-fascist Italians. In the Allied-held south, the Kingdom of Italy officially became a co-belligerent of the Allies and declared war on Germany on 13 October 1943.

The Military Administration in France was an interim occupation authority established by Nazi Germany during World War II to administer the occupied zone in areas of northern and western France. This so-called zone occupée was established in June 1940, and renamed zone nord ("north zone") in November 1942, when the previously unoccupied zone in the south known as zone libre ("free zone") was also occupied and renamed zone sud ("south zone").

Its role in France was partly governed by the conditions set by the Armistice of 22 June 1940 after the blitzkrieg success of the Wehrmacht leading to the Fall of France; at the time both French and Germans thought the occupation would be temporary and last only until Britain came to terms, which was believed to be imminent. For instance, France agreed that its soldiers would remain prisoners of war until the cessation of all hostilities.

Free France (French: France libre) was a resistance governmentclaiming to be the legitimate government of France following the dissolution of the Third Republic during World War II. Led by General Charles de Gaulle, Free France was established as a government-in-exile in London in June 1940 after the Fall of France to Nazi Germany. It joined the Allied nations in fighting Axis forces with the Free French Forces (Forces françaises libres), supported the resistance in Nazi-occupied France, known as the French Forces of the Interior, and gained strategic footholds in several French colonies in Africa.

Following the defeat of the Third Republic by Nazi Germany, Marshal Philippe Pétain led efforts to negotiate an armistice and established a German puppet state known as Vichy France. Opposed to the idea of an armistice, de Gaulle fled to Britain and from there broadcast the Appeal of 18 June (Appel du 18 juin) exhorting the French people to resist the Nazis and join the Free French Forces. On 27 October 1940, the Empire Defense Council (Conseil de défense de l'Empire)—later the French National Committee (Comité national français or CNF)—formed to govern French territories in central Africa, Asia, and Oceania that had heeded the 18 June call.
