British Legions
The British Legion or British Legions were foreign volunteer units that fought under Simón Bolívar against Spain for the independence of Colombia, Venezuela, Ecuador and José de San Martín for the independence of Peru in the Spanish American wars of independence. Venezuelans generally called them the Albion Legion. They were composed of over seven thousand volunteers, mainly Napoleonic War veterans from Great Britain and Ireland, as well as some German veterans and some locals recruited after arriving in South America. Volunteers in the British Legion were motivated by a combination of both genuine political motives and mercenary motives.
Their greatest achievements were at the Boyacá, Carabobo, Pichincha and Battle of Ayacucho which secured independence for Colombia, Venezuela, Ecuador and Peru from Spanish rule respectively.
Background
At the end of the Napoleonic Wars the British Empire no longer required a large standing army. In April 1817, The Times calculated that there were 500,000 ex-soldiers in a British population of 25 million. After a quarter-century of Continental wars—both the wars against Revolutionary France and the Napoleonic Wars—these men had no other employment history or trade and, therefore, often found themselves in poverty.South America's wars of independence from Spain provided many of them with an opportunity to continue their military careers and escape from the prospect of inactivity and poverty at home. Many Britons were still concerned by the threat that Spain, as a restored world power, potentially posed to Britain. Despite Spain and Britain having been allies in the Peninsular War just a few years before, many Britons' image of the Spanish in America was influenced by the now-disputed Black Legend.
The motivations of volunteers for the British Legions varied. Volunteers were also motivated by the liberal propaganda of Simon Bolívar's supporters that portrayed the war as bringing freedom and rights to people under Spanish tyranny. For these reasons, particularly the former, the recruiting of British volunteers received tacit government support, even if in principle the British Crown discontinued its support to the insurgents after the Congress of Vienna in 1814. Mercenary interests also played a large part in motivating potential recruits, who were often unemployed, and perceived South America as a place where they would be able to continue to earn a living.
Formation
From May 1817, the British volunteers were mainly recruited in London by Bolivar's agent, Luis Lopez Mendez with the probable approval of the Duke of Wellington. The recruits were encouraged by promises of pay equivalent to the British army and by promotion to one rank above that which they had held in the army. Pay was to commence upon arrival in Venezuela and when the call was heard on the streets of London thousands began to volunteer for the expedition and soon the first five detachments were formed as follows:| Early Formation | Number |
| 1st Venezuelan Hussars: Colonel Gustavus Hippisley | 30 officers and 160 NCOs |
| 2nd Venezuelan Hussars : Colonel Henry Wilson | 20 officers and 100 NCOs |
| 1st Venezuelan Lancers: Colonel Robert Skeene | 20 officers and 200 NCOs |
| 1st Venezuelan Rifles: Colonel Donald Campbell | 37 officers and 200 NCOs |
| Brigade of Artillery: Colonel Joseph Gilmour | 10 officers and 80 NCOs 5 6-pounders, 1 5½ howitzer |
Campaigns
The soldiers used Margarita Island as their base. Conditions there were poor and some died of disease. To replace losses they recruited 100 locals into their ranks.| Expedition embarked Under command: | Number of Soldiers |
| Colonel Hippisley | 720 |
| Colonel James Towers English | 1,200 |
| Colonel Elson | 572 |
| General John D’Evereux | 1,729 |
| General Gregor MacGregor | 600 |
| Colonel Meceroni | 300 |
| Colonel James Rooke | 200 |
| Others | 387 |
| Total | 5,508 |
Colombia and Venezuela
They took part in the campaign of the Venezuelan Llanos in 1818 and fought at the battles of El Sombrero, El Semén, Ortiz, Rincón de los Toros and Calabozo. These first recruits from Britain made a good impression on Bolivar who was anxious to secure the services of more British volunteers. In March 1819, Bolivar combined most of his foreign volunteers into a brigade of 250 men named the British Legions, with James Rooke as commander. George Elsom, who had formerly been an ensign with a militia regiment near London and who had sailed with Hippisley’s expedition, returned to London to recruit. Amongst his recruits were some 110 Hanoverians, who were commanded by John Uslar who saw action at Waterloo with the King’s German Legion.In June 1819 Elsom arrived at the mouth of the Orinoco with the first wave of British troops. They numbered some 2,200 men equipped and uniformed, under the command of Captain George Gibson and twenty officers. This Second British Legion’ as it became known consisted of the 1st British Legion led by Colonel James Towers English, the 2nd British Legion led by Colonel John Blossett, and the Irish Legion, led by Colonel William Aylmer.
The Legion adopted the motto Morir o vencer, as well as an anthem, composed to the tune of Ye Gentlemen of England which was continually played by the Legion’s band. The uniforms were similar to those worn by the British army which had been supplied by the firm of Herring and Richardson who had also fitted out the ships. In Ireland a similar recruiting process took place. Led by John D’Evereux who enlisted 1700 men which became known as the Irish Legion.
The Rifle Battalion joined the same month which saw Bolivar reorganise his forces. The Rifles, reinforced by another 350 British troops who had recently arrived in South America, were then formed into two battalions. The first was to be commanded by Colonel Arthur Sandes and the second by Major John Mackintosh who would later become a military aide-de-camp to Simon Bolivar and Antonio Jose de Sucre.
The British Legions after months of inactivity joined Bolivar's army on the Plains of Apure towards the end of 1818 but saw no serious action until March 19, 1819, in a skirmish in the woods of Gamarra. They would soon become an important part of Bolívar's army. They had to endure the secretive and brutal crossing of the Andes from May to June during which the Patriot army suffered greatly including the British.
They played a pivotal role however in the Vargas Swamp Battle on July 25. During this action Bolivar found himself in a difficult position; the left flank of the Patriot army was outflanked and withdrew in disorder. Rooke then led the 2nd Rifles against the Spanish positions on the hills. A ferocious bayonet charge regained the positions for the Patriots. Rooke fell mortally wounded while Sandes was also wounded twice. Despite heavy casualties the British troops distinguished themselves.
At the Battle of Boyacá on August 7, 1819, Sandes' Rifles Battalion led a bayonet charge on the royalist artillery which turned the tide of the battle. Bolivar credited them with the victory saying "those soldier-liberators are the men who deserve these laurels" They were awarded with the ‘Order of the Liberator’ one of the rare occasions during the war when this decoration was bestowed onto an entire unit.
At the victory of Carabobo the legion troops were led by Colonel Thomas Ilderton Ferrier. They fought in the battle as part of the 1st Division, led by General Jose Antonio Paez. They defended strategically important hills while being greatly outnumbered and low on supplies; their heroic stand was the decisive moment of the day. They suffered 119 casualties, of those were two officers with Ferrier among the dead. Bolívar described the Legions and all who served in them as "the saviours of my country". As a reward for their service, they were given the Carabobo battle honour by the general staff of the Patriot forces, and all its personnel rewarded with the Liberators' Star by Bolívar himself, 20 days after the battle.
Ecuador and Perú
With the independence of Colombia and Venezuela secured, Bolivar and his patriot army along with the British Legions moved South to drive the Spanish out of Peru and Ecuador. They marched over the mountains again this time to a land of high volcanoes where they managed to force the Spanish to withdraw at the Battle of Bomboná on April 7, 1822. The following month the Legions assisted Sucre's army and marched higher still to Quito standing at 9,300 feet in the mountains. There on 24 May 1822, they fought on the flanks of a volcano at the Battle of Pichincha. The battle could have turned into a rout if the British and Irish troops had not thwarted a dangerous flank attack by the veteran Spanish Aragón battalion. The victory at Pichincha for the Patriot army secured independence for Ecuador.They took part in the last major campaign of the Independence wars in Peru during 1824; British volunteers, including the 1st Rifles under Sandes, were present at the Battle of Junin in August and the Battle of Ayacucho in December which marked the end of Spanish rule in South America.
