Royal Irish Regiment of Foot Guards

The Royal Irish Regiment of Foot Guards, or "His Majesty’s Regiment of Guards in Ireland", was a regiment of foot guards first raised in 1662 for service in Ireland. Part of the Royal Irish Army of Charles II, it was initially garrisoned around Dublin.

During the 1688 Glorious Revolution the Foot Guards under their commanding officer William Dorrington stayed loyal to James II, and fought on the Jacobite side in the Williamite War in Ireland. After the 1697 Peace of Ryswick and the formal disestablishment of James’s army in exile, the Foot Guards were immediately reconstituted in French service as Dorrington’s Regiment, retaining their red coats and Saint George's Cross standard. As part of the Irish Brigade they distinguished themselves in a number of campaigns.

Renamed the Regiment Roth after a subsequent colonel, Michael Roth, and later still as the Regiment Walsh, the regiment did not formally disband until 1791.

Formation
Charles II issued the order for the regiment's creation in April 1662, soon after the Restoration. The remainder of the 7,500-strong army formed in Ireland at this point was not formally regimented until the 1670s, and contained many Cromwellian veterans. Leading Royalist James Butler, 1st Duke of Ormond was given the commission to raise the regiment and authority to appoint junior officers; the experienced Anglo-Irish soldier Sir William Flower was made lieutenant-colonel, while Ormonde’s son Richard Butler, 1st Earl of Arran was gazetted colonel, with captaincy of a company. Other commissions were given to members of Ormonde's circle such as Sir Nicholas Armorer and Sir John Stephens of Finglas.

The regiment was initially established at 1200 men in 12 companies, plus officers; it also included a chaplain, surgeon, drum-major and 24 drummers along with a piper to the "King's Company". Many of the rank and file were raised in England, apparently to minimise Cromwellian influence, with further recruits from the ranks of the Irish “Independent Companies”. Up until 1688 members of the Guards were quartered either in Dublin Castle or in the city gatehouses.

Early service
Under Arran, the Guards were employed largely on peacetime duties in Ireland: they were used to suppress a mutiny by other regiments in Carrickfergus in 1666, while in 1673 two companies were ordered to Chester and saw service on board ship during the Third Anglo-Dutch War. Nevertheless the regiment retained a high prestige: a Major Billingsley recorded that "to be a Major of the Royal Regiment of Guards is better and more honourable than to be a Lieutenant-Colonel of any other regiment", while the Lord Lieutenant of Ireland, Clarendon, wrote approvingly of their appearance on parade.

For the first twenty years of its history the regiment was almost exclusively Protestant, with most of its officers drawn from the Irish Protestant gentry. However the 1685 accession of Charles’s Catholic brother James accelerated the recruitment of Catholics, particularly as officers. James’s associate Richard Talbot, 1st Earl of Tyrconnell replaced a number of the rank and file, giving the pretext that “the King would have all his men young and of one size”; veteran lieutenant-colonel Sir Charles Feilding was replaced by William Dorrington, an English Catholic. Dorrington continued reforming the regiment, though Clarendon criticised him for recruiting at the Catholic shrine St James's Well, feeling it would harm relations with the Catholic community.

Arran died in 1686 and his nephew James, Lord Ossory, later the 2nd Duke of Ormonde was briefly made colonel of the Guards: at the time of the Glorious Revolution, Ormonde switched his allegiance to William of Orange. He was replaced as colonel by Dorrington and the majority of the regiment stayed loyal to James, although one of its two battalions, sent to England immediately prior to William's landing, was taken prisoner.

The Guards subsequently fought on the Jacobite side in the War in Ireland, including at the Siege of Derry, the Battle of the Boyne and at Aughrim, where their lieutenant-colonel William Mansfield Barker was killed. Several hundred of their number were among those permitted to leave for France after the Jacobite defeat. Following their departure, there would be no Irish Guards regiment until the formation of the Irish Guards in 1900.

French service
In France the regiment continued to recruit from among Irish Jacobite exiles, the so-called “Wild Geese”, and saw further service in the Nine Years' War. The terms of the Peace of Ryswick included the disbandment of James’s former army, but the same day as the Guards regiment was broken up, 27 February 1698, it was immediately reconstituted as Dorrington's Regiment in the French Army.

The regiment continued in French service in several campaigns. It fought at Malplaquet, Dettingen and Fontenoy. Dorrington ended his active service in c.1710 and died in 1718; Michael Roth, who had begun service with the Foot Guards as a lieutenant in 1686, became colonel, followed by his son Charles Edward, Comte de Roth, in 1733. Elements of the regiment returned to Britain during the Jacobite Rising of 1745.

Between 1766 and 1770 the regiment’s colonel was the 9th Earl of Roscommon; its last colonel was Antoine Walsh, also known as the Comte de Walsh-Serrant. In 1791, following the French Revolution, it was merged into the 92nd Regiment of the French Army. The latter, today based in Clermont-Ferrand, is considered the last French regiment to descend directly from the regiments of the Irish Brigade.

Uniform and colours
Throughout most of its existence, even in French service, the regiment was issued with red coats with blue facings. Its colours, a Saint George's Cross with a central crown surmounted with a crowned lion, reflected its original status as a Guards regiment of the King of England.
