Origin and History

This regiment is older than what its rank indicated. He had initially been raised in 1661 by Charles II under the title of “Royal-Irlandais” from the remnants of the Irish units in the French service which had been disbanded after the Treaty of the Pyrenees. This regiment returned to Great Britain when Charles II was recalled.

The regiment was soon renamed “Gardes Irlandaises” defended the crown of James II up to the last moment. After the capitulation of Limerick, the regiment entered into the French service and, on October 9, 1689, embarked for Brest.

For many years, Louis XIV, for the sake of James II, maintained the regiment out of the French Army, as an auxiliary unit which initially served on the coasts of Normandie.

In 1692, during the Nine Years' War (1688–97), the regiment received James' authorisation to join a French army campaigning in the Low Countries and took part in the siege of Huy. In 1693, it fought in the Battle of Landen. It later took part in the capture of Charleroi.

On February 27, 1698, after the signature of the Treaty of Ryswick, the “Gardes Irlandaises” were disbanded and their officers and soldiers joined the same day a new regiment of fifteen companies which took the name of its colonel, Lord Dorrington.

In 1701 and 1702, at the outbreak of the War of the Spanish Succession (1701-13), the regiment served in Alsace. In 1703, it took part in the siege and capture of Kehl, in the attack of the Lines of Stollhofen, in the combats of Hornberg and Munderkingen, in the Battle of Höchstädt and in the capture of Kempten, Augsburg and Ulm; in 1704, in the disastrous Battle of Blenheim; in 1706, in the relief of Fort-Louis and in the capture of Drusenheim, Lauterbourg and the Marquisat Island; and in 1707, in the attack on the Lines of Stollhofen, in the capture of Ettlingen, Pforzheim, Wynhing (probably Winnenden) and Schorndorf, and in the combat of Seckingen. In 1708, the regiment was transferred to Flanders. In 1709, it took part in the Battle of Malplaquet and in the unsuccessful defence of Béthune; in 1711, in the attack on Arleux; in 1712, in the victorious Battle of Denain and in the sieges and recapture of Douai, Le Quesnoy and Bouchain; and in 1713, in the siege and recapture of Landau and in the siege of Freiburg.

In 1741 and 1742, during of the War of the Austrian Succession (1740-48), the regiment was employed at the guard of the frontiers of Flanders. In 1743, it was sent to the Palatinate and took part in the Battle of Dettingen. In 1744, it participated in the sieges of Menin, Ypres and Furnes; in 1745, in the Battle of Fontenoy and in the sieges of Tournai, Oudenarde, Termonde and Ath. In 1746, the regiment took part in the expedition of Charles Edward Stuart (aka Bonnie Prince Charlie) in Scotland. On April 16 of the same year, the Comte de Rooth was taken prisoner at the Battle of Culloden. The regiment then returned to France. On July 2, 1747, the regiment fought in the Battle of Lauffeld and then formed part of the army covering the siege of Berg-Op-Zoom. In 1748, it took part in the siege of Maastricht.
