[1] In 1635, this company became the Régiment d'Anguien-Cavalerie, after its proprietor Louis, Duke of Enghien (the future Grand Condé), one of twelve regiments formed by a royal order of 16 May to fight in the war against the Holy Roman Empire.

[2] Sent to fight in the Pyrenees in the war against Spain, the Anguien-Cavalerie participated in the unsuccessful Siege of Fuenterrabía, during which their commander de Tavannes was killed.

[2] During 1642 to 1643, the regiment fought in the Reapers' War under Marshal Philippe de La Mothe-Houdancourt, helping gain large sections of the Principality of Catalonia for the French–Catalan alliance.

The regiment was sent to the siege of Dunkirk, where on 26 December 1646 it was renamed the Régiment de Condé-Cavalerie, after Enghien became Prince of Condé on the death of his father.

The Condé-Cavalerie was sent to Catalonia for two years, while Prince Louis was assigned to command the French and Catalan forces, where it took part in the unsuccessful second siege of Lleida.

[2] In early 1649, the regiment was called to join the blockade of Paris as part of the First Fronde, a rebellion of the French parliament and a section of the nobles, including the Prince of Condé.

[2] The regiment returned to royal service on 7 November 1659, following the Treaty of the Pyrenees, reduced to a single "colonel's company", belonging to the Prince of Condé.

In 1675 the regiment took Dinant, Huy, and Limbourg, and spent 1676 campaigning in the Saar valley and concluded the war fighting in the Battle of Kokersberg in 1677.

[2] On the outbreak of the War of the Polish Succession in 1733, the Condé-Cavalerie was sent to the Rhine valley, where it fought at the sieges of Kehl and Philippsburg, and the battles of Ettlingen and Clausen.

[2] In the early years of the War of the Austrian Succession, the regiment served in Westphalia, Bavaria, and Bohemia until its return to France in July 1743.

At the Battle of Krefeld on 23 June 1758, the men of the regiment fought fiercely, and helped put up a strong fighting retreat after the French defeat.

The brilliant colonel of that regiment, the Count of Toulouse-Lautrec, had previously been chosen to serve as the mestre de camp lieutenant of the Condé-Cavalerie.

[7] Around this time, Jaucourt went into exile and command of the regiment briefly passed to Colonel Emmanuel de Grouchy, a future Marshal of France.

[4] In 1800, the regiment was part of the Army of the Rhine, in Marshal Laurent de Gouvion Saint-Cyr's Centre Corps, fighting at the battles of Biberach and Hohenlinden.

A small detachment served in the French invasion of Russia in 1812 as part of Marshal Pierre Augereau's reserve XI Corps.

That year, the regiment incorporated 25 survivors from the Compagnie des Guides-interprètes (the predecessors of the later French corps of Interprètes Militaires or military interpreters), which was first formed at Boulogne in 1803 in preparation for Napoleon's planned invasion of the United Kingdom.

[18] During the July Monarchy, the 2nd Dragoon Regiment dropped the name Doubs, and was among several that were favoured by Louis Philippe I, and called to the maneuvers and festivities at his camp at Compiègne every two years.

[23] In January 1854, while the Crimean War was ongoing, a detachment of half a squadron of the 2nd Dragoons was sent to the Kingdom of Greece, where it attempted to control the local "bandits" for about a year.

By his speeches and pamphlets, and his encouragement of skiing (at a dedicated chalet near Campan) and a wide range of sports and other recreation, he kept morale high.

[33] The 2nd Dragoon Regiment was officially disbanded on 29 November 1942 by its superior officer General Louis Gustave Bérard, commander of the 17th Military Region.

At the ceremony of farewell to the regimental standard, Colonel Schlesser gave a dramatic speech in which he proclaimed that "despite [his] determination to resist" he was forced "with tears in [his] eyes and heart full of bitterness, to obey".

[33][34] Although many of the men who headed for North Africa were delayed by imprisonment in neutral Spain, most of them eventually were released and transported to Casablanca by Free French merchant vessels.

[34] On 7 November 1943, plans to revive the 2nd Dragoons in the Free French Army were finalised and the regiment was designated as a tank destroyer unit; it was re-formed on 21 December 1943, at Sfax, Tunisia.

[4] At a ceremony attended by a number of senior French and Allied officers, General Henri Giraud formally returned the regiment's standard, to its new commander, Lieutenant Colonel de Sauzey.

The regiment embarked in Mers-el-Kebir and Oran on 25 August, and spent five days in the crossing to Provence, during which Colonel Schlesser radioed in an encouraging message.

Covering the left flank of the Corps, it reached Paray-le-Monial, where it met the 8th Dragoon Regiment of the French Forces of the Interior, which from then served as its infantry support.

[32] On 10–11 September, the regiment linked up at Saulieu with U.S. troops who had landed in Normandy, the 86th Cavalry Reconnaissance Squadron (Mechanized) (part of the 6th Armored Division).

[38] In January 2015, soldiers of the regiment were deployed to Guinea to provide decontamination for medical personnel fighting the West African Ebola epidemic.

[38][41] From its base, the 2nd Dragoon Regiment runs Detecbio, a network of environmental monitoring sensors that can detect a variety of potential biological threats.

[4][45] The badge of the regiment consists of a black, winged dragon holding a guidon of the Condé-Cavalerie (showing the fawn side with the sun and pyre), on a blue background.
