The regiment's ancestry is drawn from two separate units, one originating in a squadron of the Hussards de la Liberté and the other in the Régiment des Guides.
The Revolutionary Wars
Its origins lay in the Hussards de la Liberté, set up on 2 September 1792 and by a royal decree dated 23 November 1792. This unit was divided into two squadrons of 200 men each and came ninth in the army order of precedence by a decree of the French National Convention of 4 June 1793. On 25 March 1793, that unit's second squadron became the 10th Hussar Regiment. On 4 June 1794, after the defection of the 4th Hussar Regiment, the 10th Hussar Regiment was re-numbered as the 9th Hussar Regiment. In 1795, the regiment was involved in the Vendée Revolt. It was part of the Army of the Rhine in 1796 and the Army of the Danube in 1798. It was known as the Hussards Rouges or Red Hussars after its scarlet dolmans.
Meanwhile, in 1852, the Régiment des Guides was formed. On 1 May 1854 this became the régiment des guides de la Garde Impériale, then in 1871 a new 9th Hussar Regiment.
World War I
The 9th Hussars were mobilized on 2 August 1914, commanded by Colonel Burette. The regiment was positioned between 14th and 21st Corps, fighting in the Battle of the Frontiers. On 19 September, the regiment was transported by rail to the Somme where it faced the 21st Prussian Corps. The 9th Hussars became part of the 1st Cavalry Corps on 21 October and participated in the Race to the Sea. Brought back to Amiens in December, the 9th Hussars were in operations on the Somme until August 1916. On 6 August 1916, the regiment was relocated to take part in the Second Battle of Champagne, as part of 14th Corps. The 9th Hussars attacked on 26 September, suffering heavy losses. After the offensive, the regiment was moved to Montbéliard. In response to the German attacks at Verdun, the regiment was transferred to the Meuse on 29 February 1916. In December 1917, the regiment was moved to the Somme again and left on 28 May for the Chemin des Dames. The regiment took part in the Battle of Malmaison from 16 August to 23 October. In November, the 9th Hussars were withdrawn and stationed in Villiers-Cotterets. In January 1918, the regiment moved to Alsace. As part of 14th Corps, the 9th Hussars retreated to the Somme after the Spring Offensive in early April. The regiment participated in the Fifth Battle of Ypres in the last months of the war. The regiment was disbanded in 1922 at Chambéry, where it was then on garrison duties.
It was briefly re-formed in 1944, before being permanently re-created on 20 May 1956 at Sissonne to fight in Oranie. In 1962 it served as the garrison at Reims, before being disbanded on 1 June 1964, becoming the 18th Dragoon Regiment as the Reims garrison. On 1 July 1964 it was recreated for the Algerian War before being finally disbanded in 1979.
