TheFlight of the Wild Geese was the departure of an IrishJacobite army under the command ofPatrick Sarsfield from Ireland to France, as agreed in theTreaty of Limerick on 3 October 1691, following the end of theWilliamite War in Ireland. More broadly, the termWild Geese is used inIrish history to refer to Irish soldiers who left to serve in continental European armies in the 16th, 17th and 18th centuries.[1]
An earlier exodus in 1690, during the same war, had formed the FrenchIrish Brigade, who are sometimes misdescribed as Wild Geese.

The first Irish troops to serve as a unit for a continental power formed anIrish regiment in the SpanishArmy of Flanders in theEighty Years' War in the 1590s.[2] The regiment had been raised by an English Catholic,William Stanley, in Ireland from native Irish soldiers and mercenaries, whom the English authorities wanted out of the country. (See alsoTudor conquest of Ireland). Stanley was given a commission byElizabeth I and was intended to lead his regiment on the English side, in support of the DutchUnited Provinces. However, in 1585, motivated by religious factors and bribes offered by the Spaniards,[citation needed] Stanley defected to the Spanish side with the regiment. In 1598 Diego Brochero de Anaya wrote to the Spanish KingPhilip III:
that every year Your Highness should order to recruit in Ireland some Irish soldiers, who are people tough and strong, and nor the cold weather or bad food could kill them easily as they would with the Spanish, as in their island, which is much colder than this one, they are almost naked, they sleep on the floor and eat oats bread, meat and water, without drinking any wine.[3]
The unit fought in the Netherlands until 1600 when it was disbanded due to heavy wastage through combat and sickness.
Following the defeat of the Gaelic armies of theNine Years' War, the "Flight of the Earls" took place in 1607. The Earl of TyroneHugh O'Neill, the Earl of TyrconnellRory O'Donnell and the Lord of Beare and Bantry,Donal O'Sullivan, along with many chiefs,Gallowglass, and their followers fromUlster, fled Ireland. They hoped to get Spanish help in order to restart their rebellion in Ireland,[4] but KingPhilip III of Spain did not want a resumption of war with England and refused their request.[5]
Nevertheless, their arrival led to the formation of a new Irish regiment in Flanders, officered by Gaelic Irish nobles and recruited from their followers and dependents in Ireland. This regiment was more overtly political than its predecessor in Spanish service and was militantly hostile to English Protestant rule of Ireland. The regiment was led by Hugh O'Neill's son John. Prominent officers includedOwen Roe O'Neill andHugh Dubh O'Neill.[6]
A fresh source of recruits came in the early 17th century, whenRoman Catholics were banned from military and political office in Ireland. As a result, the Irish units in the Spanish service began attracting CatholicOld English officers such asThomas Preston andGarret Barry. These men had more pro-English views than their Gaelic counterparts and animosity was created over plans to use the Irish regiment to invade Ireland in 1627. The regiment was garrisoned inBrussels during the truce in theEighty Years' War from 1609 to 1621 and developed links with Irish Catholic clergy based in theseminary there, creating theIrish Colleges – includingFlorence Conroy.
Many of the Irish troops in Spanish service returned to Ireland after theIrish Rebellion of 1641 and fought in the armies ofConfederate Ireland – a movement of Irish Catholics. When the Confederates were defeated and Ireland occupied after theCromwellian conquest of Ireland, around 34,000 Irish Confederate troops fled the country to seek service in Spain. Some of them later deserted or defected to French service, where the conditions were deemed better.
During the 18th century, Spain's Irish regiments saw service not only in Europe but also in the Americas. As examples, the Irlanda Regiment (raised 1698) was stationed in Havana from 1770 to 1771, theUltonia Regiment (raised 1709) in Mexico from 1768 to 1771, and theRegiment of Hibernia (raised 1709) in Honduras from 1782 to 1783.[7]
At the time of theNapoleonic Wars all three of these Irish infantry regiments still formed part of the Spanish army. Heavy losses and recruiting difficulties diluted the Irish element in these units, although the officers remained of Irish ancestry. The Hibernia Regiment had to be reconstituted with Galician recruits in 1811 and ended the war as an entirely Spanish corps.[8] All three regiments were finally disbanded in 1818 on the grounds that insufficient recruits, whether Irish or other foreigners, were forthcoming.[9]

From the mid-17th century or so, France overtook Spain as the destination for Catholic Irishmen seeking a military career. The reasons for this included the increased overlap between French and Irish interests, and the ease of migration to France and Flanders from Ireland.[10]
France recruited many foreign soldiers during various periods; Germans, Italians, Irish, Scottish and Swiss. André Corvisier, the authority on French military archives, estimates that foreigners accounted for around 12% of all French troops in peacetime and 20% of troops during warfare.[11] In common with the other foreign troops the Irish regiments were paid more than their French counterparts. Both Irish and Swiss regiments in French service wore red uniforms, though this had no connection with theredcoats of the British army.[12]
The crucial turning point came during theWilliamite War in Ireland (1688–91), whenLouis XIV gave military and financial aid to the IrishJacobites. In 1690, in return for 6,000 French troops that were shipped to Ireland, Louis demanded 6,000 Irish recruits for use in theNine Years' War against the Dutch. Five regiments, led by Justin McCarthy, Viscount Mountcashel formed the nucleus of Mountcashel's FrenchIrish Brigade. A year later, after the Irish Jacobites underPatrick Sarsfield agreed to favourable peace terms and capitulated at theTreaty of Limerick in 1691, the fully armed and equipped Irish Army withdrew to France.[13]
Sarsfield sailed to France on 22 December 1691, leading 19,000 of his countrymen and countrywomen to enter the French service in the first phase of the military denuding of Ireland. Sarsfield's exodus included 14,000 soldiers and around 6,000 women and children. This event began what is remembered in Ireland as theFlight of the Wild Geese. In a poem two centuries later,W. B. Yeats would mourn:
Was it for this the Wild Geese spread
A grey wing on every tide…
Sarsfield's Irish army was regrouped and equipped in their red coats, symbolizing their allegiance to the Stuart king. In 1692, a large Franco-Irish army had assembled on the French coast for an invasion of England, but the proposed invasion was scuppered due to the French naval defeat atBattles of Barfleur and La Hogue. Sarsfield's Wild Geese were then re-grouped on the same footing as Mountcashel's Irish Brigade.[14]
Up until 1745, the Catholic Irish gentry were allowed to discreetly recruit soldiers for French service. The authorities in Ireland saw this as preferable to the potentially disruptive effects of having large numbers of unemployed young men of military age in the country. However, after a composite Irish detachment from the French Army (drawn from each of the regiments comprising the Irish Brigade and designated as "Irish Picquets") was used to support theJacobite rising of 1745, the British authorities realised the dangers of this policy and banned recruitment for foreign armies in Ireland. After this point, the rank and file of the Irish units in French service were increasingly non-Irish, although the officers continued to be recruited from Ireland.
During theSeven Years' War efforts were made to find recruits from among Irish prisoners of war or deserters from the British Army. Otherwise, recruitment was limited to a trickle of Irish volunteers who were able to make their own way to France, or from the sons of former members of the Irish Brigade who had remained in France. During the Seven Years' War, the Irish Regiments in French service were: Bulkeley, Clare, Dillon, Rooth, Berwich and Lally. Additionally, there was a regiment of cavalry:Fitzjames. By the end of the 18th century, even the officers of the Irish Regiments were drawn from Franco-Irish families who had settled in France for several generations. While often French in all but name, such families retained their Irish heritages.[15]
Following the outbreak of theFrench Revolution, the Irish Brigade ceased to exist as a separate entity on 21 July 1791 when the 12 non-Swiss foreign regiments then in existence were integrated into the line infantry of the French Army. Although the remaining Irish regiments: Dillon's, Berwick's and Walsh's, lost their distinctive red uniforms and separate status, they were still known informally by their traditional titles. Many individual Franco-Irish officers left the service in 1792 whenLouis XVI was deposed, as their oath of loyalty was to him and not to the French nation.
In 1803Napoleon Bonaparte raised a light infantry Irish unit composed mainly of veterans of theIrish Rebellion of 1798. Napoleon'sIrish Legion originally comprised one under-strength battalion but it was later raised to a regiment comprising four battalions and a regimental depot or headquarters. The Legion was designated as a distinctly Irish unit from its establishment. The intention was that the Legion would spearhead an invasion of Ireland, supported by French troops.[16] The unit was dressed in emerald-green uniforms faced with gold and received their regimental colour of a gold harp in each corner on a green background inscribed with "Le Premier Consul aux Irlandos Uni" ("The First Consul to United Ireland") and on the obverse; "Liberte des Conscience/Independence d'Irlande" ("Freedom of Conscience/Independence to Ireland"). In December 1804 they received a new Colour and Napoleon's cherished bronze-cast Imperial Eagle.[17] Many officers from the ancien régime Irish Brigade also joined the unit, where it gained distinction in theWalcheren Expedition in the Low Countries and during thePeninsular War, in particular during theSiege of Astorga (1812) where an Irish detachment of elite voltigeurs formed the "forlorn hope" and led the assault battalion, comprising the 47th Regiment of the Line, which stormed through the breach, taking cover all night under heavy fire inside the city's walls. By morning the defenders surrendered as they were out of ammunition. The last significant action involving the unit was during thesiege of Antwerp in 1814, when the Irish Legion defended the city for three months against an Anglo-Prussian force which had landed in the Low Countries to defeat Napoleon. The siege was lifted after Napoleon's abdication and the unit was shortly afterwards disbanded, ending a 125-year-old Irish military tradition in France.[18]
Despite being less studied, the ancient and traditional "mestiere delle armi" in Italy was also a well-known profession by the Irish. The "tercio" of Lucas Taf (around 500 men) served in Milan towards 1655. The Army of Savoy included also Irishmen, but in Italy, the Irish were organized basically by the Spanish administration. In 1694, another regiment in Milan was exclusively composed of Irishmen. Around 3–4% of a total of 20,000 men were Irish in the Spanish Army of Milan. It is not a high figure, but it was important as regards quality. In this context,James Francis Fitz-James Stuart (1696–1739), Duke of Berwick and of Liria is just one example of this success. He began to serve the monarchy in 1711 and succeeded in becoming General Lieutenant (1732), ambassador in Russia, in Austria and in Naples, where he died.[19] In 1702, an Irish grenadier company led by Francis Terry entered Venetian service. This company ofJacobite exiles served at Zara until 1706. Colonel Terry became the Colonel of a Venetian Dragoon Regiment, which the Terry family mostly commanded until 1797. Colonel Terry's Dragoons uniforms were red-faced blue in the Irish tradition. The Limerick Regiment, of Irish Jacobites, transferred from Spanish service to that of theBourbon king ofSicily in 1718.
Throughout this period, there were also substantial numbers of Irish officers and men in the armies or service of European powers, including the AustrianHabsburg Empire.[20][21] It was not uncommon for Irish commanders of the Habsburg Empire to encounter enemy armies led by other Irishmen. One such example wasPeter Lacy, afield marshal in the Imperial Russian Army, whose sonFranz excelled in the Austrian service.[22] GeneralMaximilian Ulysses Browne, the Austrian commanding officer in theBattle of Lobositz, was also of Irish descent.[23] Recruitment for Austrian service included areas of the midlands of Ireland, and members of theTaaffe, O'Neill and Wallis families served with Austria.[24] Count Alexander O'Nelly (O'Neill), who came from Ulster, commanded the 42nd Bohemian Infantry Regiment from 1734 to 1743. Much earlier, in 1634, during theThirty Years' War, Irish officers led by Walter Deveraux assassinated generalAlbrecht von Wallenstein on the orders of the Emperor. In the late 18th and throughout the 19th century, further Irish officers served in the Habsburg Empire, soAndreas O'Reilly von Ballinlough (1742–1832),[25] whose military service extended through theSeven Years' War, theWar of the Bavarian Succession, theAustro-Turkish War, theFrench Revolutionary Wars, and theNapoleonic Wars, furthermoreLaval Graf Nugent von Westmeath andMaximilian Graf O’Donnell von Tyrconnell, who saved the life ofEmperorFranz Joseph I during an assassination attempt.Gottfried von Banfield finally became the most successfulAustro-Hungarian naval aeroplanepilot in the First World War.
In 1609,Arthur Chichester, thenLord Deputy of Ireland, deported 1,300 former rebel Irish soldiers fromUlster to serve in the ProtestantSwedish Army. However, under the influence of Catholic clergy, many of them deserted to Polish service.
The Catholic Irish troops in Protestant Swedish service changed sides during theBattle of Klushino, against largely Catholic Poland, the only European country withstatutoryfreedom of religion at the time.[citation needed] The Irish then served in Polish service for several years during thePolish–Muscovite War (1605–1618), until their wages went unpaid.[26]
Irish recruitment for continental armies declined sharply after it was made illegal in 1745. In practical terms, this meant that recruiting within Ireland itself effectively ceased and Irishmen seeking employment in foreign armies had to make their own way to the Continent. Replacements accordingly were drawn increasingly from the descendants of Irish soldiers who had settled in France or Spain; from non-Irish foreign recruits such as more readily available Germans or Swiss; or from natives of the recruiting countries.
In 1732, Sir Charles Wogan indicated in a letter toDean Swift that 120,000 Irishmen had been killed and wounded in foreign service "within these forty years",[27] with Swift later replying:
I cannot but highly esteem those gentlemen of Ireland who, with all the disadvantages of being exiles and strangers, have been able to distinguish themselves by their valour and conduct in so many parts of Europe, I think, above all other nations.[28]
As noted above, as late as the late 1780s, there were still three Irish regiments in France.[29] During the Napoleonic Wars at least nominally Irish units continued to serve in the Spanish and French armies. At the time of theFranco-Prussian War a volunteer Irish medical unit, theFranco-Irish Ambulance Brigade, was serving with the French Army.[30]
It was some time before the British armed forces began to tap into Irish Catholic manpower. In the late 18th century, thePenal Laws were gradually relaxed and in the 1790s the laws prohibiting Catholics from bearing arms were abolished. Thereafter, the British began recruiting Irish regiments for the Crown Force – including for such units as theConnaught Rangers. Several more Irish-labelled units were created in the 19th century. By 1914 infantry regiments in the British Army that were associated with Ireland included thePrince of Wales's Leinster Regiment, theRoyal Dublin Fusiliers, theIrish Guards, theRoyal Irish Regiment, theRoyal Inniskilling Fusiliers, theRoyal Irish Rifles, theRoyal Irish Fusiliers, the Connaught Rangers and theRoyal Munster Fusiliers. With the creation of theIrish Free State in 1922, five of the above regiments were disbanded, with most of the remainder undergoing a series of amalgamations between 1968 and 2006. The United Kingdom still retains four Irish-named regiments: theIrish Guards, theRoyal Irish Regiment, theScottish and North Irish Yeomanry, and theLondon Irish Rifles. TheQueen's Royal Hussars, the successor regiment of theQueen's Royal Irish Hussars, and theRoyal Dragoon Guards, the successor regiment of the4th Royal Irish Dragoon Guards and the5th Royal Inniskilling Dragoon Guards, maintain the Irish heritage of their antecedent regiments through their uniforms, regimental bands and traditions, such as the celebration ofSt. Patrick's Day.
The term "Wild Geese" is sometimes used metaphorically to refer toIrish emigrants. This usage can be seen, for example in theIrish Times, which has a recurrent section called Wild Geese in which "Irish people working abroad tell their stories".[31]
