The Army of Condé (French: Armée de Condé) was a French field army during the French Revolutionary Wars. One of several émigré field armies, it was the only one to survive the War of the First Coalition; others had been formed by the Comte d'Artois (brother of King Louis XVI) and Mirabeau-Tonneau. The émigré armies were formed by aristocrats and nobles who had fled from the violence in France after the August Decrees. The army was commanded by Louis Joseph de Bourbon, Prince de Condé, the cousin of Louis XVI of France. Among its members were Condé's grandson, the Duc d'Enghien and the two sons of Louis XVI's younger brother, the Comte d'Artois, and so the army was sometimes also called the Princes' Army.

The Chasseurs Britanniques was a battalion-sized corps of foreign volunteers, who fought for the United Kingdom of Great Britain and Ireland during the Napoleonic Wars. The regiment was formed from the remnants of the Prince of Condé's Army after it was disbanded in 1800. The regiment entered British service in 1800 and continued to fight for the United Kingdom until 1814, when it was disbanded after Napoleon's first abdication and exile to Elba.

The Chasseurs Britanniques Regiment was formed as the Revolutionary Wars that had racked Europe for many years slowly drew to a close. The reasons the men, and especially the officers, came to form a new regiment in the British Army were rooted in those wars and the upheaval in France that had ignited them. After extensive service in the Mediterranean, the Regiment joined Wellington's army in the Iberian Peninsula in 1811. It formed the nucleus of a
new division, the 7th, nicknamed the 'Mongrels'. The soldiers of the Chasseurs Britanniques, from practically every European nation, served in Wellington's major battles such as Fuentes de Onoro, Salamanca and Vittoria as well as less famous operations, for instance the attempted storm of Fort San Cristobal (1811), at Llerena (1812) and in fighting above the Bidassoa (1813). This book sets out to tell the story of their formation and role in some detail. This is explained in the wider strategic context with the contribution of the other units the Chasseurs served alongside, especially those in the same brigade of the 7th Division, being described fully. Officers and men of the Regiment appear throughout and illustrate the diversity of the unit
