The Action of 3 July 1810 was a minor naval engagement of the Napoleonic Wars, in which a French frigate squadron under Guy-Victor Duperré attacked and defeated a convoy of Honourable East India Company East Indiamen near the Comoros Islands. During the engagement the British convoy resisted strongly and suffered heavy casualties but two ships were eventually forced to surrender. These were the British flagship Windham, which held off the French squadron to allow the surviving ship Astell to escape, and Ceylon. The engagement was the third successful French attack on an Indian Ocean convoy in just over a year, the French frigates being part of a squadron operating from the Île de France under Commodore Jacques Hamelin.

The Action of 15 November 1810 was a minor naval engagement fought during the British Royal Navy blockade of the French Channel ports in the Napoleonic Wars. British dominance at sea, enforced by a strategy of close blockade, made it difficult for the French Navy to operate even in their own territorial waters. In the autumn of 1810, a British squadron assigned to patrol the Baie de la Seine was effectively isolating two French squadrons in the ports of Le Havre and Cherbourg. On 12 November, the squadron in Le Havre, consisting of frigates Elisa and Amazone attempted to reach Cherbourg at night in order to united the squadrons. This squadron was spotted in the early hours of 13 November by the patrolling British frigates HMS Diana and HMS Niobe, which gave chase.

The Action of 18 September 1810 was a naval battle fought between British Royal Navy and French Navy frigates in the Indian Ocean during the Napoleonic Wars. The engagement was one of several between rival frigate squadrons contesting control of the French island base of Île de France, from which French frigates had raided British trade routes during the war. The action came in the immediate aftermath of the Battle of Grand Port, in which four British frigates had been lost, and just four days after a fifth British frigate had been captured and subsequently recaptured in the Action of 13 September 1810. In consequence of the heavy losses the British force had suffered, reinforcements were hastily rushed to the area and became individual targets for the larger French squadron blockading the British base at Île Bourbon.

The Adriatic campaign of 1807–1814 was a struggle for supremacy in the Adriatic Sea between the French Navy and the British Royal Navy during the Napoleonic Wars. The early stages of the campaign saw extensive activity between rival frigate squadrons, climaxing at the Battle of Lissa in 1811 at which the last major French force was destroyed and its commander killed. The subsequent campaign was characterised by sustained raids by British warships on French and Italian convoys, warships and coastal positions across the Adriatic, culminating in the capture of several key French port cities in 1813, during the War of the Sixth Coalition.

The Adriatic campaign was a minor theatre of war during the Napoleonic Wars in which a succession of small British Royal Navy and Austrian Navy squadrons and independent cruisers harried the combined naval forces of the First French Empire, the Kingdom of Italy, the Illyrian Provinces and the Kingdom of Naples between 1807 and 1814 in the Adriatic Sea. Italy, Naples and Illyria were all controlled either directly or via proxy by the French Emperor Napoleon I, who had seized them at the Treaty of Pressburg in the aftermath of the War of the Third Coalition.

In the Siege of Almeida, the French corps of Marshal Michel Ney captured the border fortress from Brigadier General William Cox's Portuguese garrison. This action was fought in the summer of 1810 during the Peninsular War portion of the Napoleonic Wars. Almeida is located in eastern Portugal, near the border with Spain.

During the Napoleonic Wars, the Anglo-Russian War was the phase of hostilities between Great Britain and Russia after the latter signed the Treaty of Tilsit that ended its war with France. Anglo-Russian hostilities were limited primarily to minor naval actions in the Baltic Sea and Barents Sea.

During the Napoleonic Wars until 1810, Sweden and Great Britain were allies in the war against Napoleon. As a result of Sweden's defeat in the Finnish War and the Pomeranian War, and the following Treaty of Fredrikshamn and Treaty of Paris, Sweden declared war on Great Britain. The bloodless war, however, existed only on paper, and Britain was still not hindered in stationing ships at the Swedish island of Hanö and trade with the Baltic states.
The siege of Astorga was an attempt by French forces to capture Astorga, Spain in a campaign of the Peninsular War. Astorga was located on the flank of the French invasion of Spain and Portugal, and was meant to be used as a headquarters during the campaign. For several weeks no attack took place, as neither side had artillery enough to fight well. Shortly after the French guns arrived, however, a hole was made in the wall and the city fell shortly thereafter. The French overpowered the Spanish garrison inside and took the city on April 20, 1810; with a loss of 160 men.

The Battle of Buçaco or Bussaco, fought on 27 September 1810 during the Peninsular War in the Portuguese mountain range of Serra do Buçaco, resulted in the defeat of French forces by Lord Wellington's Anglo-Portuguese Army.

The Battle of Fuengirola was an engagement between a small Army of the Duchy of Warsaw garrison of a medieval Moorish fortress in Fuengirola against a much larger Anglo-Spanish expeditionary corps under Andrew Blayney. Blayney led an amphibious assault on Sohail Castle under heavy bombardment. The defenders, fighting with the First French Empire, were men from the 4th Regiment of the Duchy of Warsaw. Under ferocious attack from sea and on land from the British and Spanish forces from the inland, about 300 Polish troops ultimately routed the assaulting forces, inflicting heavy losses on the highly reputed British 89th Regiment of Foot among others and even captured Blayney himself, who was a very distinguished general. Several of the Polish officers were awarded the Legion of Honour by Napoleon himself.

The Battle of Loznica or Battle of Tičar was fought on 17–18 October 1810 between the Serbian Revolutionaries and the Ottoman Army in Loznica, western Serbia.

The Battle of Monte de las Cruces was one of the pivotal battles of the early Mexican War of Independence, in October 1810.

The Combat of the Côa was a skirmish that occurred during the Peninsular War period of the Napoleonic Wars. It took place in the valley of the Côa River and it was the first significant battle for the new army of 65,000 men controlled by Marshal André Masséna, as the French prepared for their third invasion of Portugal.

The Battle of the Tiger's Mouth was a series of engagements between a Portuguese flotilla stationed in Macau, and the Red Flag Fleet of the Chinese pirate Ching Shih, led by her second-in-command, the notorious Cheung Po Tsai - known among the Portuguese as Cam Pau Sai or Quan Apon Chay. Between September 1809 and January 1810, the Red Flag Fleet suffered defeat at the hands of the Portuguese fleet led by José Pinto Alcoforado e Sousa, within the Humen Strait - known to the Portuguese as the Boca do Tigre - until finally surrendering formally in February 1810. As her fleet surrendered, Ching Shih herself abandoned piracy on the occasion.

In the Battle of Baza on 4 November 1810 an Imperial French force commanded by General Milhaud fought a Spanish corps led by General Blake. When the Spanish commander allowed his forces to get spread out, Milhaud attacked with his cavalry and crushed Blake's vanguard with heavy losses. The Spanish force retreated into the province of Murcia. Baza is located on Route 342 about 80 kilometres (50 mi) north of Almería. The battle occurred during the Peninsular War, part of the Napoleonic Wars.

The Bolivian war of independence began in 1809 with the establishment of government juntas in Sucre and La Paz, after the Chuquisaca Revolution and La Paz revolution. These Juntas were defeated shortly after, and the cities fell again under Spanish control. The May Revolution of 1810 ousted the viceroy in Buenos Aires, which established its own junta. Buenos Aires sent three military campaigns to the Charcas, headed by Juan José Castelli, Manuel Belgrano and José Rondeau, but the royalists ultimately prevailed over each one. However, the conflict grew into a guerrilla war, the War of the Republiquetas, preventing the royalists from strengthening their presence. After Simón Bolívar and Antonio José de Sucre defeated the royalists in northern South America, Sucre led a campaign that was to defeat the royalists in Charcas for good when the last royalist general, Pedro Antonio Olañeta, suffered death and defeat at the hands of his own defected forces at the battle of Tumusla. Bolivian independence was proclaimed on August 6 of 1825.

The Battle of Buçaco or Bussaco, fought on 27 September 1810 during the Peninsular War in the Portuguese mountain range of Serra do Buçaco, resulted in the defeat of French forces by Lord Wellington's Anglo-Portuguese Army.

The Siege of Cádiz was a siege of the large Spanish naval base of Cádiz by a French army from 5 February 1810 to 24 August 1812 during the Peninsular War. Following the occupation of Seville, Cádiz became the Spanish seat of power, and was targeted by 70,000 French troops under the command of the Marshals Claude Victor and Nicolas Jean-de-Dieu Soult for one of the most important sieges of the war. Defending the city were 2,000 Spanish troops who, as the siege progressed, received aid from 10,000 Spanish reinforcements as well as British and Portuguese troops.

The Battle of Campichuelo was a battle fought on 19 December 1810 between revolutionary forces led by Manuel Belgrano and Royalist troops on the right bank of the Paraná River, part of the Paraguay campaign of the Argentine War of Independence. It ended with a victory for the forces of Belgrano.

In the Siege of Ciudad Rodrigo, the French Marshal Michel Ney took the fortified city from Field Marshal Don Andrés Perez de Herrasti on 10 July 1810 after a siege that began on 26 April. Ney's VI Corps made up part of a 65,000-strong army commanded by André Masséna, who was bent on a third French invasion of Portugal.

The Battle of Cotagaita was fought on October 27, 1810 during the Campaign of Upper Peru in the Argentine War of Independence when the troops of the Army of the North were sent by the Primera Junta government in Buenos Aires to the Alto Perú to fight the Royalists. It was the first skirmish of the Army of the North in this theatre. The battle was fought near the town of Santiago de Cotagaita, nowadays in Potosí Department in Bolivia.

Hans Axel von Fersen, known as Axel de Fersen in France, was a Swedish count, Marshal of the Realm of Sweden, a General of Horse in the Royal Swedish Army, one of the Lords of the Realm, aide-de-camp to Rochambeau in the American Revolutionary War, diplomat and statesman, and a friend of Queen Marie-Antoinette of France. He died at the hands of a Stockholm lynch mob.

The first Upper Peru campaign was a military campaign of the Argentine War of Independence, which took place in 1810. It was headed by Juan José Castelli, and attempted to expand the influence of the Buenos Aires May Revolution in Upper Peru. There were initial victories, such as in the Battle of Suipacha and the revolt of Cochabamba, but it was finally defeated during the Battle of Huaqui that returned Upper Peru to Royalist influence. Manuel Belgrano and José Rondeau would attempt other similarly ill-fated campaigns; the Royalists in the Upper Peru would be finally defeated by Sucre, whose military campaign came from the North supporting Simón Bolívar.

The Battle of Grand Port was a naval battle between squadrons of frigates from the French Navy and the British Royal Navy. The battle was fought during 20–27 August 1810 over possession of the harbour of Grand Port on Isle de France during the Napoleonic Wars. The British squadron of four frigates sought to blockade the port to prevent its use by the French through the capture of the fortified Île de la Passe at its entrance. This position was seized by a British landing party on 13 August and, when a French squadron under Captain Guy-Victor Duperré approached the bay nine days later, the British commander, Captain Samuel Pym, decided to lure them into coastal waters where his superior numbers could be brought to bear against them.

The Gunboat War was the naval conflict between Denmark–Norway and the British Navy during the Napoleonic Wars. The war's name is derived from the Danish tactic of employing small gunboats against the conventional Royal Navy. In Scandinavia it is seen as the later stage of the English Wars, whose commencement is accounted as the First Battle of Copenhagen in 1801.

The Invasion of Île Bonaparte was an amphibious operation in 1810 that formed an important part of the British campaign to blockade and capture the French Indian Ocean territories of Île Bonaparte and Isle de France during the Napoleonic Wars. These islands formed a fortified base for a French frigate squadron under Commodore Jacques Hamelin to raid British convoys of East Indiamen travelling between Britain and British India. Hamelin's ships had destroyed two convoys the previous year despite the attention of a squadron of Royal Navy ships under Commodore Josias Rowley. Rowley had responded by raiding the fortified anchorage of Saint Paul on Île Bonaparte and capturing one of Hamelin's frigates and two captured East Indiamen.

The Invasion of Guadeloupe was a British amphibious operation fought between 28 January and 6 February 1810 over control of the Caribbean island of Guadeloupe during the Napoleonic Wars. The island was the final remaining French colony in the Americas, following the systematic invasion and capture of the others during 1809 by British forces. During the Napoleonic Wars, the French colonies had provided protected harbours for French privateers and warships, which could prey on the numerous British trade routes in the Caribbean and then return to the colonies before British warships could react. In response, the British instituted a blockade of the islands, stationing ships off every port and seizing any vessel that tried to enter or leave. With trade and communication made dangerous by the British blockade squadrons, the economies and morale of the French colonies began to collapse, and in the summer of 1808 desperate messages were sent to France requesting help.

The Invasion of Isle de France was a complicated but successful amphibious operation in the Indian Ocean, launched in November 1810 during the Napoleonic Wars. During the operation, a substantial British military force was landed by the Royal Navy at Grand Baie on Isle de France. Marching inland against weak French opposition, the British force was able to overwhelm the defenders in a series of minor engagements, culminating in the capture of the island's capital Port Napoleon and the surrender of Charles Decaen, the French governor. The surrender eliminated the last French territory in the Indian Ocean and among the military equipment captured were five French Navy frigates and 209 heavy cannon. Isle de France was retained by Britain at the end of the war under the name of Mauritius and remained part of the British Empire until 1968.

The Invasion of the Spice Islands was a military invasion by British forces that took place between February to August 1810 on and around the Dutch owned Maluku Islands also known as the Spice Islands in the Dutch East Indies during the Napoleonic wars.

In the Siege of Lérida from 29 April to 13 May 1810, an Imperial French army under Louis Gabriel Suchet besieged a Spanish garrison led by Jaime García Conde. On 13 May, García Conde surrendered with his 7,000 surviving soldiers. Lleida (Lérida) is a city in the western part of Catalonia. Margalef is located on Route N-240 about 10 kilometres (6 mi) southeast of Lérida. The siege occurred during the Peninsular War, part of the Napoleonic Wars.

The Battle of Manresa and Battle of Vilafranca from 21 March to 5 April 1810 saw a Spanish division led by Juan Caro and Luis González Torres de Navarra, Marquess of Campoverde attack an Imperial French brigade commanded by François Xavier de Schwarz. Caro's division first surprised the town of Vilafranca del Penedès in March and captured its 800-man garrison made up of troops from the Confederation of the Rhine. Vilafranca is located 35 kilometres (22 mi) west of Barcelona.

The Mauritius campaign of 1809–1811 was a series of amphibious operations and naval actions fought to determine possession of the French Indian Ocean territories of Isle de France and Île Bonaparte during the Napoleonic Wars. The campaign lasted from the spring of 1809 until the spring of 1811, and saw both the Royal Navy and the French Navy deploy substantial frigate squadrons with the intention of disrupting or protecting trade from British India. In a war in which the Royal Navy was almost universally dominant at sea, the campaign is especially notable for the local superiority enjoyed by the French Navy in the autumn of 1810 following the British disaster at the Battle of Grand Port, the most significant defeat for the Royal Navy in the entire conflict. After their victory, the British used the original Dutch name of Mauritius for Isle de France. In 1814, Île Bonaparte was returned to France, who eventually renamed it La Réunion.

The May Revolution was a week-long series of events that took place from May 18 to 25, 1810, in Buenos Aires, capital of the Viceroyalty of the Río de la Plata. This Spanish colony included roughly the territories of present-day Argentina, Bolivia, Paraguay, Uruguay, and parts of Brazil. The result was the removal of Viceroy Baltasar Hidalgo de Cisneros and the establishment of a local government, the Primera Junta, on May 25. The junta would eventually become the country of Argentina. It was the first successful revolution in the South American Independence process.

The Siege of Mequinenza saw a 16,000-man Imperial French corps commanded by Louis Gabriel Suchet invest a 1,000-strong Spanish garrison under Colonel Carbon. Mequinenza and its castle were captured by the French after an operation lasting about three weeks. The action occurred during the Peninsular War, which formed part of the Napoleonic Wars. Mequinenza is located at the confluence of the Ebro and Segre Rivers about 211 kilometres (131 mi) west of Barcelona.

The Peninsular War (1807–1814) was the military conflict fought by Spain and Portugal, assisted by the United Kingdom, against the invading and occupying forces of France for control of the Iberian Peninsula during the Napoleonic Wars. In Spain, it is considered to overlap with the Spanish War of Independence. The war began when the French and Spanish armies invaded and occupied Portugal in 1807 by transiting through Spain, and it escalated in 1808 after Napoleonic France had occupied Spain, which had been its ally. Napoleon Bonaparte forced the abdications of Ferdinand VII and his father Charles IV and then installed his brother Joseph Bonaparte on the Spanish throne and promulgated the Bayonne Constitution. Most Iberians rejected French rule and fought a bloody war to oust them. The war on the peninsula lasted until the Sixth Coalition defeated Napoleon in 1814, and it is regarded as one of the first wars of national liberation and is significant for the emergence of large-scale guerrilla warfare.

The 1804–1813 Russo-Persian War was one of the many wars between the Persian Empire and Imperial Russia, and began like many of their wars as a territorial dispute. The new Persian king, Fath Ali Shah Qajar, wanted to consolidate the northernmost reaches of his kingdom—modern-day Georgia—which had been annexed by Tsar Paul I several years after the Russo-Persian War of 1796. Like his Persian counterpart, the Tsar Alexander I was also new to the throne and equally determined to control the disputed territories.

The Russo-Turkish War (1806–1812) between the Russian Empire and the Ottoman Empire was one of the Russo-Turkish Wars. Russia prevailed, but both sides wanted peace as they feared Napoleon's moves to the east.

Battle of Silda was a naval battle fought on 23 July 1810 between the United Kingdom of Great Britain and Ireland and Denmark–Norway near the Norwegian island of Silda in Sogn og Fjordane county. The battle occurred during the Gunboat War, itself part of the Napoleonic Wars. In the battle, two British frigates captured or destroyed three or four Dano-Norwegian gunboats. The Danish and British accounts of the battle differ.

The Battle of Suipacha was fought on 7 November 1810 in Bolivia during the Bolivian War of Independence between the Spanish colonial army and the Republican forces sent by the Primera Junta from Buenos Aires. At the time Bolivia was known as Upper Peru. It was the first decisive defeat of the Royalists by Republican forces. The battle took place 25 km (16 mi) southeast of Tupiza, near the small town of Suipacha, on the margin of the Suipacha river in the Sud Chichas province.

The Siege of Tortosa pitted an Imperial French army under General Louis Gabriel Suchet against the Spanish defenders of Tortosa led by General Lilli, Conde de Alacha. The siege progressed swiftly and Alacha surrendered on 2 January 1811. Tortosa is a city that lies on the Ebro River about 80 kilometres (50 mi) southwest of Tarragona. The action took place during the Peninsular War, part of the Napoleonic Wars.

The Battle of Vich or Battle of Vic on 20 February 1810 saw a Spanish force under Henry O'Donnell suddenly attack a 5,500-man Imperial French division led by Joseph Souham. After bitter fighting the French prevailed, forcing O'Donnell's men to retreat. The engagement occurred during the Peninsular War, part of the Napoleonic Wars. Vic is located 60 kilometres (37 mi) north of Barcelona in the province of Catalonia.

The West Florida Controversy included two border disputes that involved Spain and the United States in relation to the region known as West Florida over a period of 37 years. The first dispute commenced immediately after Spain received the colonies of West and East Florida from the Kingdom of Great Britain following the American Revolutionary War. Initial disagreements were settled with Pinckney's Treaty of 1795.
