Battle of Boyacá (1819): Bolívar's Victory for New Granada

The Battle of Boyacá was fought on 7 August 1819 at a bridge over the Teatinos River near Tunja, in the highlands of New Granada, now Colombia. Simón Bolívar’s patriot army, after an epic march across flooded plains and the Andes, defeated and captured the royalist army defending Bogotá. The victory ended Spanish rule over most of New Granada and became the founding battle of the Colombian nation.

Background

The Spanish American independence movements began after Napoleon’s invasion of Spain in 1808. In New Granada and Venezuela, local juntas formed in 1810, but rival patriot factions and royalist resistance weakened the first republics. In 1815–1816 a Spanish army under General Pablo Morillo reconquered New Granada and executed many patriot leaders in a period remembered as the Reign of Terror.

Simón Bolívar, born in Caracas in 1783, had led the struggle in Venezuela with mixed fortunes. By 1818 he had established a base at Angostura on the Orinoco, allied with the llanero horsemen of José Antonio Páez and reinforced by British and Irish volunteers, many of them veterans of the Napoleonic Wars. In the plains of Casanare, east of the Andes, Francisco de Paula Santander was organising New Granadan exiles into a new army.

Morillo’s main forces remained in Venezuela. Bolívar saw that New Granada, held by a smaller royalist army under Colonel José María Barreiro, was vulnerable, and that its people were tired of royalist repression.

The march across the plains and the Andes to Boyacá

Bolívar left the Apure region in late May 1819, at the height of the rainy season. His men waded for days through flooded plains, often waist-deep, carrying weapons and powder above the water. In June they joined Santander at Tame, giving a combined force of perhaps 3,500–4,000 men.

Instead of using an easier route, Bolívar chose the Páramo de Pisba, a cold, high pass that the royalists believed impassable in that season. The crossing in early July cost the army many soldiers, who died of cold and exposure, and almost all its horses and cattle. The exhausted survivors reached Socha on about 6 July, where local people gave them food and clothing.

Barreiro concentrated his army to block the patriots. On 25 July 1819 the two sides fought at the Pantano de Vargas, near Paipa. The battle was going badly for the patriots until a cavalry charge led by Colonel Juan José Rondón turned the tide, and the royalists fell back.

Bolívar then slipped past Barreiro and seized Tunja on 5 August, placing himself between the royalist army and Bogotá. The town’s capture also gave the patriots weapons, supplies and fresh recruits, and showed the people of the highlands that the royalists could be beaten. Barreiro had to march south to protect the capital, along a route that crossed the Teatinos River at the bridge of Boyacá.

The battle

On the afternoon of 7 August, the royalist vanguard reached the bridge while the main body was still on the road behind. Santander’s division attacked the vanguard at the bridge, while José Antonio Anzoátegui led the main patriot force against the royalist centre on the higher ground. Royalist units were separated and could not support each other.

The fighting lasted around two hours. The royalist army broke, and Barreiro was captured, according to tradition by a young soldier, Pedro Pascasio Martínez, who refused a bribe to let him go. Each side had roughly 2,800–3,000 men. Royalist losses were around 100 killed and about 1,600 captured, while Bolívar reported 13 killed and 53 wounded.

Consequences

When news of the defeat reached Bogotá, Viceroy Juan Sámano fled the city in disguise. Bolívar entered Bogotá on 10 August 1819 and was received as a liberator. Royal treasury funds and weapons left behind helped pay for the next campaigns. Across the highlands, towns declared for the patriots, and royalist garrisons in other parts of New Granada withdrew or surrendered over the following months.

Bolívar left Santander in charge of New Granada. On 11 October 1819, while Bolívar was away, Santander had Barreiro and some 37 or 38 other captured officers shot in Bogotá’s main square, an act still debated by historians.

On 17 December 1819 the Congress of Angostura proclaimed the Republic of Colombia, uniting New Granada, Venezuela and, in principle, Quito. Historians call it Gran Colombia to distinguish it from modern Colombia. Bolívar went on to free Venezuela at Carabobo in 1821 and Ecuador after the Battle of Pichincha in 1822.

Key people

Simón Bolívar’s strategic gamble, crossing the Andes in the rainy season, was the key to victory. Francisco de Paula Santander, later vice-president and president, organised the Casanare army and led the attack at the bridge. José Antonio Anzoátegui commanded the main assault but died of illness in November 1819. Juan José Rondón’s charge at Pantano de Vargas is celebrated in Colombia’s large Monument to the Lancers.

Legacy

Boyacá is to Colombia what Yorktown or Valmy are to other nations, a founding victory. The bridge has been rebuilt and the battlefield is a national monument, with statues of Bolívar and the heroes of the campaign. Every 7 August is a national holiday, and Colombian presidents take office on that date. The department of Boyacá is named after the battle site.

Foreign volunteers

From 1817 several thousand volunteers from Britain and Ireland sailed to join Bolívar, recruited by agents in London and Dublin after the end of the Napoleonic Wars left many soldiers unemployed. Units known collectively as the British Legion took part in the 1819 campaign. At Pantano de Vargas their commander, Colonel James Rooke, was badly wounded; his arm was amputated and he died soon afterwards. The volunteers’ discipline was valued, though many others died of disease or deserted in the harsh conditions of the plains.

By the numbers

Figures come from contemporary reports and later histories and vary between sources.

Boyacá is sometimes described as a huge clash. In reality it was a modest battle by European standards, decided in a short afternoon of fighting. Its importance came from timing and position: Bolívar had placed his army between Barreiro and the capital, so the royalist defeat left Bogotá and the viceroy’s treasury undefended. The harder test of the campaign had been the march across the plains and the Páramo de Pisba, where the army lost more men than in all its battles.

Why it matters

The Battle of Boyacá turned the independence war in northern South America in the patriots’ favour. By freeing New Granada, Bolívar gained a secure base, money and recruits, making the final liberation of Venezuela, Ecuador and Peru possible.
