Philippe Pétain in the context of "Académie Française"

The Battle of Verdun (French: Bataille de Verdun [bataj də vɛʁdœ̃]; German: Schlacht um Verdun [ʃlaxt ʔʊm ˈvɛɐ̯dœ̃]) was fought from 21 February to 18 December 1916 on the Western Front in France. The battle was the longest of the First World War and took place on the hills north of Verdun. The German 5th Army attacked the defences of the Fortified Region of Verdun (RFV, Région Fortifiée de Verdun) and those of the French Second Army on the right (east) bank of the Meuse. Using the experience of the Second Battle of Champagne in 1915, the Germans planned to capture the Meuse Heights, an excellent defensive position, with good observation for artillery-fire on Verdun. The Germans hoped that the French would commit their strategic reserve to recapture the position and suffer catastrophic losses at little cost to the German infantry.

Poor weather delayed the beginning of the attack until 21 February but the Germans captured Fort Douaumont in the first three days. The advance then slowed for several days, despite inflicting many French casualties. By 6 March, 20+1⁄2 French divisions were in the RFV and a more extensive defence in depth had been organised. Philippe Pétain ordered there to be no retreat and that German attacks were to be counter-attacked, despite this exposing French infantry to the German artillery. By 29 March, French guns on the west bank had begun a constant bombardment of Germans on the east bank, causing many infantry casualties. The German offensive was extended to the west bank of the Meuse to gain observation and eliminate the French artillery firing over the river but the attacks failed to reach their objectives.

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 Government of Vichy France was the collaborationist ruling regime or government in Nazi-occupied France during the Second World War. Of contested legitimacy, it was finally headquartered in the town of Vichy in occupied France, but it initially took shape in Bordeaux under Marshal Philippe Pétain as the successor to the French Third Republic in June 1940. The government remained in Vichy for four years, but was escorted to Germany in September 1944 after the Allied invasion of France. It then operated as a government-in-exile until April 1945, when the Sigmaringen enclave was taken by so-called Free French forces. Pétain was permitted to travel back to France (through Switzerland), by then under control of the technically illegal Provisional French Republic, and subsequently put on trial for treason.

The Sigmaringen enclave was a temporary government-in-exile formed by remnants of France's Nazi-collaborating Vichy regime during the final stages of World War II. Established in the requisitioned Sigmaringen Castle in southwestern Germany, it was created after the German military evacuated key Vichy officials, including Marshal Philippe Pétain and other collaborators, to avoid capture by advancing Allied forces. Though coerced into relocation, Pétain and ex-Prime Minister Pierre Laval refused to cooperate, leaving leadership to figures like Fernand de Brinon and Marcel Déat, who sought to maintain a semblance of legitimacy.

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.

The 1917 French Army mutinies took place amongst French Army troops on the Western Front in northern France during World War I. They started just after the unsuccessful and costly Second Battle of the Aisne, the main action in the Nivelle Offensive in April 1917. The new French commander of the armies in France, General Robert Nivelle, had promised a decisive victory over the Germans in 48 hours; morale in French armies rose to a great height and the shock of failure soured their mood overnight.

The mutinies and associated disruptions involved, to various degrees, nearly half of the French infantry divisions stationed on the Western Front. The term "mutiny" does not precisely describe events; soldiers remained in trenches and were willing to defend but refused orders to attack. Nivelle was sacked and replaced by General Philippe Pétain, who restored morale by talking to the men, promising no more suicidal attacks, providing rest and leave for exhausted units and moderating discipline. He held 3,400 courts martial in which 554 mutineers were sentenced to death and 26 were executed.
