Emigre units made up a sizable portion of the British Army during the Napoleonic Wars. Emigres were foreign troops in British service who chose to form regiments of a similar group.
One of the most notable units of emigres was the Kin’s German Legion, or the KGL. Made up of predominately Hanoverians, the KGL was created in 1803 from the remnants of the French controlled areas in Germany. The House of Hanover, who were in control of the British crown, helped to influence many Germans to choose the path of Britain rather than fighting for their new French leaders. The KGL consisted of 8 battalions of line infantry, 5 regiments of cavalry, and 6 batteries of artillery. There were about 14,000 troops in the KGL- the most of any emigre unit by far. They served throughout many campaigns of the Napoleonic Wars, notably in the Peninsula and in the Hundred Days. They fought at Bussaco, Salamanca, Vittoria, and Waterloo. They were most notably involved in the fighting at La Haye Sainte, described in The Longest Afternoon.
The Royal Corsican Rangers, a unit of riflemen formed on the island of Corsica, began in 1794 with the aid of Corsican revolutionary Pasquale Paoli. By 1798, British General Ralph Abercromby made them an independent unit as they began to fight in Italy against Napoleon’s forces. Most notably, the Corsicans clashed with French troops at Maida in Sicily. The unit was stationed in Corfu later on until they were disbanded in 1817. Another of the Emigres was the Royal Sicilian Regiment founded in 1806 with 1,300 troops. Maj.-Gen. John Stuart created the unit who served on Malta and on their home island of Sicily.
One of the more famous and peculiar units was the Chasseurs Britanniques, made up of deserters from France. Many of them were people who were targeted in the revolution or people who were not allowed back in France. Over 1,700 troops fought in the Chasseurs Britanniques and they served widely around the world. They fought in the Egypt Campaign, in the Peninsula, and in the War of 1812 in the United States. The unit was disbanded in 1814 after Napoleon’s first exile.
The King’s Dutch Legion (KDL) was formed in 1799 after King William V left Holland after the French invaded and created the puppet state of the Batavian Republic. William V’s legion consisted of 5000 infantrymen and artillery and the unit served in the 1798 Irish Rebellion before they were disbanded in 1802. Another Dutch-inspired unit was the Regiment de Meuron because they were in Dutch East India Company (VOC) service. The Swiss mercenaries numbered about 900 and were transferred to the British after the formation of the Batavian Republic. They fought both in the Peninsula and in the United States.
