Maxime Weygand (; 21 January 1867 – 28 January 1965) was a French military commander in World War I and World War II, as well as a high-ranking member of the Vichy regime.

Born in Belgium, Weygand was raised in France and educated at the Saint-Cyr military academy in Paris. After graduating in 1887, he went on to become an instructor at the Saumur Cavalry School. During World War I, Weygand served as a staff officer to General (later Marshal) Ferdinand Foch. He then served as an advisor to Poland in the Polish–Soviet War and later High Commissioner of the Levant. In 1931, Weygand was appointed Chief of Staff of the French Army, a position he served until his retirement in 1935 at the age of 68.

In May 1940, without any experience in a field command leading troops in battle, Weygand was recalled for active duty and assumed command of the French Army during the German invasion. Following a series of military setbacks, Weygand advised armistice and France subsequently capitulated. He joined Philippe Pétain's Vichy regime as Minister for Defence and served until September 1940, when he was appointed Delegate-General in French North Africa. He was noted for exceptionally harsh implementation of German antisemitic policies while in this position. Despite this, Weygand favoured only limited collaboration with Germany and was dismissed from his post in November 1941 on Adolf Hitler's demand. Following the Allied invasion of North Africa in November 1942, Weygand was arrested by the Germans and imprisoned at Itter Castle in Austria until May 1945. After returning to France, he was held as a collaborator at the Val-de-Grâce but was released in 1946 and cleared of charges in 1948. He died in January 1965 in Paris at the age of 98.

Early years

Weygand was born on 21 January 1867, allegedly at 39 Boulevard de Waterloo in Brussels, of unknown parents. The biographer Bernard Destremau gave five possible sets of parents: Leopold II with either the wife of the Austrian diplomat Count Zichy or an anonymous Mexican woman (dismissed as doubtful); Charlotte, wife of then-Archduke Maximilian of Austria, and the Belgian officer Alfred van der Smissen (the most widely supported); a tutor named David Cohen and a French woman named Thérèse Denimal ("lacks credibility"); Charlotte and a Mexican Colonel Lopez ("difficult to hide"); and Maximilian of Austria and a Mexican dancer called Lupe. The various theories of Mexican extraction, however, require some kind of record forgery; regardless, Weygand's short stature and appearance may suggest a partially-European antecedence with a connection to the Austrian court suggested by the funds provided for his education in youth. In 2003, the French journalist Dominique Paoli claimed to have found evidence that Weygand's father was indeed van der Smissen, but the mother was Melanie Metternich-Zichy, lady-in-waiting to Charlotte and daughter of Klemens von Metternich. Paoli further claimed that Weygand had been born in mid-1865, not January 1867 as is generally claimed. This theory is rejected by historians as most accounts place Metternich-Zichy in European circles, not Mexico, at the time Weygand was conceived.

Regardless, throughout his life, Weygand maintained he did not know his true parentage. While an infant he was sent to Marseille to be raised by a widow named Virginie Saget, whom he originally took to be his mother. At the age of seven, he was transferred to the household of David Cohen, an Italo-Belgian leather merchant in Marseille, with partner Thérèse Denimal (later de Nimal). Then-called Maxime de Nimal, he attended schools in Cannes and then Asniéres, fees likely paid by the Belgian royal household or government, where his scholastic accomplishment were recognised. He was transferred to a boarding school in Paris and thence to the Lycée Louis-le-Grand where Maxime was baptised Catholic. After a disciplinary issue he was expelled and barred from Parisian schools, ending up at schools in Toulon and then Aix-en-Provence. Returning to Paris some years later, he was rejected from the French Navy and decided to seek admission to the École spéciale militaire de Saint-Cyr. Admitted in the top half of the class, he was denied a full French uniform due to his unclear heritage, but the slight ignored he graduated in the top ten of his class. Highly competent at fencing and horsemanship, he was accepted as a junior cavalry officer at Saumur – connecting him to a network of upper-class officers – but again rejected as a non-citizen. After some payments by David Cohen, Maxime was adopted by an accountant in Arras called Francis-Joseph Weygand. Taking the name Maxime Weygand, he was posted to a French cavalry regiment in October 1888.

He says little about his youth in his memoirs, devoting to it only four pages out of 651. He mentions the gouvernante and the aumônier of his college, who instilled in him a strong Catholic faith. His memoirs essentially begin with his entry into the preparatory class of Saint-Cyr Military School in Paris.Destremau, Bernard. Weygand. Paris: Perrin, 1989.

Military career

During the Dreyfus affair, Weygand was one of the most anti-Dreyfusard officers of his regiment, supporting the widow of Colonel Hubert-Joseph Henry, who had committed suicide after the discovery of the falsification of the charges against Captain Alfred Dreyfus.

He was promoted to captain in 1896. Weygand chose not to attempt the difficult preparation to the École Supérieure de Guerre (the French staff college) because of his desire, he said, to keep contact with the troops. This did not prevent him from later becoming an instructor at the cavalry school at Saumur. Along with Joseph Joffre and Ferdinand Foch, Weygand attended the Imperial Russian Army manoeuvres in 1910; his account mentions a great deal of pomp and many gala dinners, but also records Russian reluctance to discuss military details. Promoted with unusual rapidity to lieutenant colonel in 1912, he attended in 1913 the Centre des Hautes Etudes Militaires, set up in January 1911 to teach combined arms operations and staff work, despite not having been "breveté" (passed staff college). During his studies, he was noticed for his brilliance in staff work by Joffre and Foch. Weygand attended the last pre-war French grand manoeuvres in 1913 and commented that it had revealed "intolerable insufficiencies" such as two divisions becoming mixed up.

First World War

Early war At the outbreak of the war, he was posted as a staff officer with the 5ème Hussars. His regiment was deployed to the Franco-German border on 28 July 1914 and later fought at the Battle of Morhange. On 17 August, he became chief of staff to Ferdinand Foch, the commander of the new Ninth Army. Weygand served under Foch for much of the rest of the war.

The professional partnership between Foch and Weygand was close and fruitful, with Weygand operating as a highly competent subordinate able to translate Foch's instructions into clearer orders, analyse ideas, and collate information. Foch referred to Weygand with praise, believing that their views were practically identical. Weygand finalised the plans for the 9th Army's attack at the First Battle of the Marne and, in doing so, became one of the first staff officers to reconnoitre the battlefield from the air. Weygand supported Foch, who was appointed to coordinate the Belgian, British, and French forces in the northern sector, during the Race to the Sea and First Ypres. Weygand was promoted to full colonel in early 1915.

The mounting French casualties over the course of 1915 were reflected in Weygand's campaign notes; the need for further cooperation between French and British armies utilised Weygand's communicative skills and he developed a working relationship with some British counterparts. Weygand was promoted to général de brigade in 1916. He later wrote of the Anglo-French Somme Offensive in 1916, at which Foch commanded French Army Group North, that it had seen "constant mix-ups with an ally [the British] learning how to run a large operation and whose doctrines and methods were not yet in accordance with ours". At a meeting on 3 July 1916 where Joffre and Haig came to non-speaking terms, Weygand, Foch, and Henry Wilson were able to restore a working relationship between the armies. He also took effective command of the army group as alternate when Foch was in ill health; during tensions between Foch and subordinates, Weygand helped to mediate disputes.

After Joffre was replaced by Robert Nivelle in late 1916, criticism of Foch also intensified, leading to Foch being relieved of his northern command; Weygand saw the politician's treatment of Foch as intolerable. At Foch's suggestion, Weygand's name was submitted for command of an infantry brigade, but after Foch was assigned out of inactivity to instead create a contingency plan for a German invasion of France via Switzerland, Weygand decided to stay with Foch. As part of this planning, Weygand served as head of a mission to Switzerland to discuss Anglo-French support if Switzerland were breached by German troops. Weygand later accompanied the British Chief of the Imperial General Staff, General Sir William Robertson, on an inspection of the Italian front in early 1917 to discuss Anglo-French support for Italy's Isonzo campaign. When Weygand and Foch were briefed on the Nivelle offensive, the two men expressed misgivings. After its failure, Nivelle was removed as French commander-in-chief and replaced with Philippe Pétain. Foch was appointed chief of the army general staff on 19 May 1917; writing to his wife, Weygand expressed his loyalty to Foch and gave up his applications for a field command.

Supreme War Council British prime minister David Lloyd George pushed for the creation of a Supreme War Council, which was formally established on 7 November 1917. Keen to sideline the British Chief of the Imperial General Staff, General William Robertson, he insisted that, as French Army chief of the General Staff, Foch could not also be French permanent military representative (PMR) on the SWC. Paul Painlevé, French prime minister until 13 November, believed that Lloyd George was already pushing for Foch to be Supreme Allied Commander so wanted him as PMR not French Chief of Staff.

The new prime minister, Georges Clemenceau, wanted Foch as PMR to increase French control over the Western Front, but was persuaded to appoint Weygand, seen very much as Foch's sidekick, instead. Clemenceau told US President Woodrow Wilson's envoy, Colonel Edward M. House that he would put in a "second- or third-rate man" as PMR and "let the thing drift where it will".

Weygand was the most junior of the PMRs (the others being the Italian Luigi Cadorna, the American Tasker H. Bliss, and the British Henry Wilson, later replaced by Henry Rawlinson). He was promoted général de division (equivalent to the Anglophone rank of major general) in 1918. This promotion was specifically because of his appointment as a PMR.

However, Clemenceau only agreed to set up an Allied General Reserve if Foch rather than Weygand were earmarked to command it. The Reserve was shelved for the time being at a SWC Meeting in London (14–15 March 1918) as the national commanders in chief, Philippe Pétain and Sir Douglas Haig, were reluctant to release divisions.

Supreme Allied Command Staff

Weygand was in charge of Foch's staff when his patron was appointed Supreme Allied Commander in the spring of 1918, and was Foch's right-hand man throughout his victories in the late summer and until the end of the war.
