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.

The Alexandria expedition of 1807 or Fraser expedition was an operation by the Royal Navy and the British Army during the Anglo-Turkish War of the Napoleonic Wars to capture Alexandria in Egypt with the purpose of securing a base of operations against the Ottoman Empire in the Mediterranean Sea. It was a part of a larger strategy against the Ottoman-French alliance of the Ottoman Sultan Selim III. It resulted in the occupation of Alexandria from 18 March to 25 September 1807. The people of Alexandria, being disaffected towards Muhammad Ali, opened the gates of the city to the British forces, allowing for one of the easiest captures of a city by the British forces during the Napoleonic Wars. Attempts to proceed inland however, were to prove disastrous with British troops being twice defeated in battles at Rosetta, at a cost of over 900 officers and men killed and more than 500 captured. Consequently, British troops were forced to retreat to Alexandria, where they remained besieged. After further inconclusive operations against the Egyptian forces and being unable to gather supplies, the British expedition was forced to embark their transports again, and leave Alexandria, not having gained any significant position of influence in Egypt or reached any specific goals towards influencing the Ottoman Empire's improving relations with France.

Attrition warfare represents an attempt to grind down an opponent's ability to make war by destroying his military resources by any means including scorched earth, people's war, guerrilla warfare and all kind of battles apart from a decisive battle. Elements of this kind of warfare had already been used in the Peninsular war. The attrition warfare against Napoleon began on 24 June 1812 when Napoleon's Grande Armée crossed the Neman River into Russia and ended on 14 December 1812 with the total defeat of the Grande Armée. A visual representation is given by the drawing of Charles Joseph Minard.

The 1814 campaign in north-east France was Napoleon's final campaign of the War of the Sixth Coalition. Following their victory at Leipzig in 1813, the Austrian, Prussian, Russian, and other German armies of the Sixth Coalition invaded France. Despite the disproportionate forces in favour of the Coalition, Napoleon managed to inflict some defeats, especially during the Six Days' Campaign. However, the campaign ended in total defeat for Napoleon as the Coalition kept advancing towards Paris as Napoleon was out of position to defend the capital, which capitulated in late March 1814. When Napoleon proposed the army march on Paris, his Marshals decided to unanimously overrule Napoleon in order to save Paris from further destruction. As a result, Napoleon was deposed and exiled to Elba and the victorious powers started to redraw the map of Europe during the First Treaty of Paris and during the early stages of the Congress of Vienna.

The French invasion of Russia, known in Russia as the Patriotic War of 1812 and in France as the Russian campaign, was begun by Napoleon to force Russia back into the Continental blockade of the United Kingdom.

The German campaign was fought in 1813. Members of the Sixth Coalition, including the German states of Austria and Prussia, plus Russia and Sweden, fought a series of battles in Germany against the French Emperor Napoleon, his marshals, and the armies of the Confederation of the Rhine - an alliance of most of the other German states - which ended the domination of the First French Empire.

The invasion of Java in 1811 was a successful British amphibious operation against the Dutch East Indian island of Java that took place between August and September 1811 during the Napoleonic Wars. Originally established as a colony of the Dutch Republic, Java remained in Dutch hands throughout the French Revolutionary and Napoleonic Wars, during which time the French invaded the Republic and established the Batavian Republic in 1795, and the Kingdom of Holland in 1806. The Kingdom of Holland was annexed to the First French Empire in 1810, and Java became a titular French colony, though it continued to be administered and defended primarily by Dutch personnel.

The second British Invasion of the Danish West Indies took place in December 1807 when a British fleet captured the Danish islands of St Thomas on 22 December and Santa Cruz on 25 December. The Danes did not resist and the invasion was bloodless. This British occupation of the Danish West Indies lasted until 20 November 1815, when Britain returned the islands to Denmark.

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.
The Jämtland Campaigns of 1808–1809 were two Dano-Norwegian military campaigns into the Swedish province of Jämtland during the Dano-Swedish War of 1808-1809.

The Java campaign of 1806–1807 was a minor campaign during the Napoleonic Wars by British Royal Navy forces against a naval squadron of the Kingdom of Holland, a client state of the French Empire, based on the island of Java in the Dutch East Indies. Seeking to eliminate any threat to valuable British merchant convoys passing through the Malacca Straits, Rear-Admiral Sir Edward Pellew determined in early 1806 that the Dutch naval forces based at Java, which included several ships of the line and three frigates, had to be defeated to ensure British dominance in the region. Lacking the forces to effect an invasion of the Dutch colony, Pellew instead sought to isolate and blockade the Dutch squadron based at Batavia in preparation for raids specifically targeting the Dutch ships with his main force.

On 1 March 1815 Napoleon Bonaparte escaped from his imprisonment on the isle of Elba, and launched a bid to recover his empire. A confederation of European powers pledged to stop him. During the period known as the Hundred Days Napoleon chose to confront the armies of Prince Blücher and the Duke of Wellington in what has become known as the Waterloo Campaign. He was decisively defeated by the two allied armies at the Battle of Waterloo, which then marched on Paris forcing Napoleon to abdicate for the second time. However Russia, Austria and some of the minor German states also fielded armies against him and all of them also invaded France. Of these other armies the ones engaged in the largest campaigns and saw the most fighting were two Austrian armies: The Army of the Upper Rhine and the Army of Italy.

The Invasion of Naples was a front during the War of the Third Coalition, in 1806, when an army of the French Empire led by Marshal André Masséna marched from northern Italy into the Kingdom of Naples, an ally of the Coalition against France ruled by King Ferdinand IV. The Neapolitan army was vanquished at Campo Tenese and rapidly disintegrated. The invasion was eventually successful despite some setbacks, including the prolonged Siege of Gaeta, the British victory at Maida, and a stubborn guerrilla war by the peasantry against the French. Total success eluded the French because Ferdinand withdrew to his domain in Sicily where he was protected by the Royal Navy and a British Army garrison. In 1806 Emperor Napoleon appointed his brother Joseph Bonaparte to rule over southern Italy as king.

The War of the Oranges was a brief conflict in 1801 in which Spanish forces, instigated by the government of France, and ultimately supported by the French military, invaded Portugal. It was a precursor to the Peninsular Wars, resulting in the Treaty of Badajoz, the loss of Portuguese territory, in particular Olivenza, as well as ultimately setting the stage for the complete invasion of the Iberian Peninsula by French forces.

The Saint-Domingue expedition was a French military expedition sent by Napoleon Bonaparte, then First Consul, under his brother-in-law Charles Victor Emmanuel Leclerc in an attempt to regain French control of the Caribbean colony of Saint-Domingue on the island of Hispaniola, and curtail the measures of independence taken by the former slave Toussaint Louverture. It departed in December 1801 and, after initial success, ended in a French defeat at the battle of Vertières and the departure of French troops in December 1803. The defeat ended forever Napoleon's dreams of a French empire in the West.

The Six Days Campaign was a final series of victories by the forces of Napoleon I of France as the Sixth Coalition closed in on Paris.

The Stecklikrieg of 1802 resulted in the collapse of the Helvetic Republic, the renewed French occupation of Switzerland and ultimately the Act of Mediation dictated by Napoleon on 19 February 1803. The conflict itself was between insurgents, mostly drawn from the rural population, and the official forces of the Helvetic Republic. The term Stäckli, or "wooden club," from which the conflict draws its name, refers to the improvised weaponry of the insurgents.

The Trachenberg Plan was a campaign strategy created by the Allies in the 1813 German Campaign during the War of the Sixth Coalition, and named for the conference held at the palace of Trachenberg. The plan advocated avoiding direct engagement with French emperor, Napoleon I, which had resulted from fear of the emperor's now legendary prowess in battle. Consequently, the Allies planned to engage and defeat Napoleon's marshals and generals separately, and thus weaken his army while they built up an overwhelming force even he could not defeat. It was decided upon after a series of defeats and near disasters at the hands of Napoleon at Lützen, Bautzen and Dresden. The plan was successful, and at the Battle of Leipzig, where the Allies had a considerable numerical advantage, Napoleon was soundly defeated and driven out of Germany, back to the Rhine. The plan was an amalgam of two prior works: the Trachenberg Protocol and the Reichenbach Plan, authored by the Austrian chief of staff of the Sixth Coalition, Joseph Radetzky von Radetz and Crown Prince of Sweden Charles John whose experience with the tactics and methods of the Grande Armée, as well as personal insight on Napoleon, proved invaluable. The combined, modified version of the two prior plans became known as the Trachenberg Plan.

The Trafalgar campaign was a long and complicated series of fleet manoeuvres carried out by the combined French and Spanish fleets; and the opposing moves of the Royal Navy during much of 1805. These were the culmination of French plans to force a passage through the English Channel, and so achieve a successful invasion of the United Kingdom. The plans were extremely complicated and proved to be impractical. Much of the detail was due to the personal intervention of Napoleon, who as a soldier rather than a sailor failed to consider the effects of weather, difficulties in communication, and the Royal Navy. Despite limited successes in achieving some elements of the plan the French commanders were unable to follow the main objective through to execution. The campaign, which took place over thousands of miles of ocean, was marked by several naval engagements, most significantly at the Battle of Trafalgar on 21 October, where the combined fleet was decisively defeated, and from which the campaign takes its name. A final mopping up action at the Battle of Cape Ortegal on 4 November completed the destruction of the combined fleet, and secured the supremacy of the Royal Navy at sea.

The Ulm campaign was a series of French and Bavarian military maneuvers and battles to outflank and capture an Austrian army in 1805 during the War of the Third Coalition. It took place in the vicinity of and inside the Swabiannl city of Ulm. The French Grande Armée, led by Napoleon Bonaparte, had 210,000 troops organized into seven corps and hoped to knock out the Austrian army in the Danube before Russian reinforcements could arrive. Rapid marching let Napoleon conduct a large wheeling maneuver, which captured an Austrian army of 23,000 under General Mack on 20 October at Ulm. That brought the total number of Austrian prisoners-of-war in the campaign to 60,000. The campaign is generally regarded as a strategic masterpiece and was influential in the development of the Schlieffen Plan in the late 19th century.

The Walcheren Campaign was an unsuccessful British expedition to the Netherlands in 1809 intended to open another front in the Austrian Empire's struggle with France during the War of the Fifth Coalition. Sir John Pitt, 2nd Earl of Chatham, was the commander of the expedition, with the missions of capturing Flushing and Antwerp in the Netherlands and enabling navigation of the Scheldt River. Some 40,000 soldiers, 15,000 horses together with field artillery and two siege trains crossed the North Sea and landed at Walcheren on 30 July. This was the largest British expedition of that year, larger than the army serving in the Peninsular War in Portugal. Nevertheless it failed to achieve any of its goals. The Walcheren Campaign involved little fighting, but heavy losses from the sickness popularly dubbed "Walcheren Fever". Although more than 4,000 British troops died during the expedition, only 106 died in combat; the survivors withdrew on 9 December.
