Prince Robert, Duke of Chartres

Prince Robert Philippe Louis Eugène Ferdinand of Orléans, Duke of Chartres (November 9, 1840, Paris – December 5, 1910, Saint Firmin) was the son of Prince Ferdinand Philippe, Duke of Orléans and thus grandson of King Louis-Philippe of France. He fought for the Union in the American Civil War, and then for France in the 1870 Franco-Prussian War. In 1863 he married his cousin Princess Françoise of Orléans in Kingston upon Thames - she was the daughter of François, Prince of Joinville. In 1886 he was exiled from France.

Life
Born in 1840, the duke was very soon orphaned - his father died in a cabriolet accident in 1842, and his mother died in 1857. Thus, during their childhood and adolescence, he and his elder brother were mainly looked after by their grandparents, king Louis-Philippe and queen Marie-Amélie of the Bourbon-Siciles. He followed the rest of the Orléans family into exile after the 1848 revolution. Louis-Philippe refused to fire upon the revolutionaries and thus abdicated his crown in favour of Robert's brother on February 24,. As a result Robert's mother Helena presented herself before the chamber of deputies to proclaim her elder son king of the French and to have herself named regent, accompanied by her brother-in-law, the Duke of Nemours, and his children. However, the assembly of Ledru-Rollin, Crémieux and Lamartine, frustrated her plans and instituted the Second French Republic. Helena and her children thus left France for Germany, whilst Louis-Philippe and the rest of the royal family moved to the United Kingdom. There they set up home in Claremont, property of King Leopold I of Belgium, himself related to Louis-Philippe. Whilst in England, in 1857 his mother Duchess Helene of Mecklenburg-Schwerin succumbed to influenza, which she passed on to Robert.

Sent to Turin for military training shortly after his mother's death, the duke of Chartres became an officer in the Piedmontese dragoons and fought in the Wars of Italian Unification on the side of France and the House of Savoy from 1859 onwards. He notably fought at the battle of Palestro, for which he was decorated by king Victor Emmanuel II.

With the outbreak of the American Civil War in April 1861, Chartres and his brother, Prince Philippe, Count of Paris, traveled to the United States to support the Union cause. On September 24, 1861, Chartres was commissioned a captain in the United States Army. He served as an assistant adjutant general on the staff of the commander of the Army of the Potomac, Major General George B. McClellan. He served in the Battle of Gaines's Mill on June 27, 1862 and resigned from the Union Army on July 15, 1862.

During their stay in the United States, the princes were accompanied by their uncle, the Prince of Joinville, who painted many watercolours of their stay. After the war, Chartres joined the Military Order of the Loyal Legion of the United States - an organization of Union officers who had served during the American Civil War.

Returning to Europe, the Duke of Chartres decided to marry but, as an exiled member of a royal house considered illegitimate by most of the reigning dynasties of the continent, found he would be unable to marry a foreign princess. He thus asked for the hand of his first cousin Françoise d'Orléans-Joinville, whom he married on June 11, 1863, in Kingston upon Thames, England. They bought and lived in a house in Ham, (now the site of the Cassel Hospital).

Finding himself in Brussels, with his uncles Prince François and Prince Henri, Duke of Aumale, in 1870 on the declaration of the Franco-Prussian War, the Duke of Chartres immediately requested Napoleon III's government for authorisation to fight in the conflict. However, the minister of war opposed Robert's participation in the was and he was thus unable to enroll in the French army until after the fall of the Empire. He then fought in the war under the pseudonym Robert Le Fort and was made head of a squadron in the Armée de la Loire, fighting with such distinction he was made a Chevalier (knight) of the Légion d'honneur once the war was over. The provisional government kept him at that rank and in 1871 sent him to Algeria to put down a native revolt.

In 1881 the Republican regime - more and more hostile to members of the Orléans and Napoléon former French royal families - removed him from his post as colonel of the 19th Mounted Chasseur Regiment. Then, in 1886, the law of exile allowed the Republican government to remove the prince from the Army list of officers and he was exiled from France.

Chartres was eventually allowed to return to France and he died in Saint-Firmin in 1910.
