Buenos Aires Campaign 1806-1807

The campaign of the River Plate in Buenos Aires during 1806 against the Spanish, ended with a British defeat in 1807.

The British Royal Navy had defeated a Franco-Spanish fleet at the Battle of Trafalgar, during October 1805. This left the Spanish with a minimal fleet in their Latin-American colonies. The British saw an opportunity to expand the British economy by having a British colony on the estuary of the River Plate. This became the beginning the Buenos Aires Campaign.

23rd June 1806, Rear-Admiral Sir Home Riggs Popham landed on the left bank of the River Plate with a force consisting of the 71st regiment of Infantry, artillery, and 1,000 men. The British force commanded by General Sir William Carr Beresford, 1st Viscount Beresford.

Subsequently the Marquis Rafael de Sobremonte heard that the British had landed. He sent Spanish troops to Montevideo thinking it would be attacked.

25th June 1806, Quilmes, near Buenos Aires had become captured by the invading British force.

27th June 1806, by the time the British had arrived at Buenos Aires, they found it almost defenceless. The Viceroy of Buenos Aires Santiago de Liniers had fled to Cordoba and became known as a coward by the population.

4th August 1806, Santiago de Liniers landed north of Buenos Aires at Las Conchas with a force of 550 veterans and 400 soldiers.

Brigadier-General Sir Samuel Auchmuty led his force of 6,000 British troops toward the city of Montevideo.

3rd February 1807, at 2am the weakest part of Montevideo city wall came under heavy bombardment by Royal Navy ships commanded by Admiral Sir Charles Stirling.

The defenders had two bastions adjacent to each other, that gave heavy fire upon the invading force. Captain Renny, 40th Regiment of Foot was killed in the attempt of gaining access to the city via the breach in the wall. However, the British suffered heavy casualties in the constant cross-fire.

Lieutenant Harry Smith of the 95th Regiment of Foot led his men through the breached wall, and also met with heavy resistance. Both Lieutenant-Colonel Brownrigg, 11th Regiment of Foot and Lieutenant-Colonel Vassal, 38th Regiment of Foot had been mortally wounded. The Spainish eventually forced became back after heavy fighting.

However, a number of troops from the 54th Regiment of Foot led a larger British force in a attack that forced the Spainish defenders back. Spainish reinforcements were en route from Buenos Aires which would have given a total of 5,000 men.

The 87th Regiment of Foot along with a company from the 95th Regiment of Foot scaled the walls and attacked the defending Spainish from behind. The 95th Regiment of Foot gained entry to the tower of the city’s cathedral armed with the latest Baker rifle. They fired upon the city’s main fortress, the Ciudadela.

Surrender of Montevideo

By 5am the Governor of Montevideo Ruiz Huidobro surrendered to Brigadier-General Sir Samuel Auchmuty. Afterwards it was reported that by 8am the civilians were going about their normal daily business and mixing with the occupying British soldiers.

Consequently, 500 Spanish troops had been killed, 600 wounded, and 2,000 taken as prisoners of war. The British had 150 dead, including 600 casualties.

Brigadier-General Robert Craufurd, Colonel Denis Pack and their 2,000 troops had become forced to retreat to the Convent of Saint Domingo. They became surrounded by 5,000 Spainish soldiers, and surrendered at 4pm.

Aftermath
