Napoleon vs. the First Coalition
The War of the First Coalition (1792–1797), one of the conflicts of the French Revolutionary Wars, was the first attempt by the European monarchies to defeat the French First Republic. France declared war on the Habsburg Monarchy of Austria in April 1792 and the Kingdom of Prussia joined the Austrian side a few weeks later. These powers made several invasions of France by land and sea, with Prussia and Austria attacking from the Austrian Netherlands and the Rhine and the Kingdom of Great Britain supporting revolts in provincial France and laying siege to Toulon. A number of smaller states, including Spain, Portugal, the Dutch Republic, were also part of the First Coalition over the course of the war.
Napoleon did not enter the war as the leader of the French army until 1796, although he faced the British forces at the 1793 Siege of Toulon, where he played a major role in crushing the royalist rebellion by expelling an English fleet and securing the valuable French harbor. Promoted to general in 1795, Napoleon was sent to the battlefields of the French Revolutionary Wars to fight the Austro-Piedmontese armies in Northern Italy the following year. Napoleon's was one of three French armies sent with the aim to eventually reach Vienna (two other engaged in the campaign on the Rhine). He was successful in a daring invasion of Italy. In the Montenotte Campaign, he separated the armies of Sardinia and Austria, defeating each one in turn, and then forced a peace on Sardinia. Following this, his army captured Milan and started the Siege of Mantua. Bonaparte defeated successive Austrian armies sent against him while continuing the siege. In February, Napoleon finally captured Mantua, with the Austrians surrendering 18,000 men. Archduke Charles of Austria was unable to stop Napoleon from invading the Tyrol and the Austrian government sued for peace in April. At the same time there was a new French invasion of Germany under Moreau and Hoche. Austria signed the Treaty of Campo Formio in October, ceding Belgium to France and recognizing French control of the Rhineland and much of Italy. The ancient Republic of Venice was partitioned between Austria and France. This ended the War of the First Coalition, although Great Britain and France remained at war.
The Mediterranean Campaign of 1798
The Mediterranean campaign of 1798 was a series of major naval operations surrounding a French expeditionary force sent to Egypt under Napoleon Bonaparte that serves as a bridge between the War of the First Coalition and the War of the Second Coalition. The French Republic sought to capture Egypt as the first stage in an effort to threaten British India and thus force Great Britain to make peace. Departing Toulon in May 1798 with over 40,000 troops and hundreds of ships, Bonaparte's fleet sailed southeastwards across the Mediterranean Sea. They were followed by a small British squadron under Rear-Admiral Horatio Nelson, later reinforced to 13 ships of the line. Bonaparte's first target was the island of Malta, which was under the government of the Knights of St. John and theoretically granted its owner control of the Central Mediterranean. Bonaparte's forces landed on the island and rapidly overwhelmed the defenders, securing the port city of Valletta before continuing to Egypt. When Nelson learned of the French capture of the island, he guessed the French target to be Egypt and sailed for Alexandria.

Despite Napoleon's initial successes, including the temporary capture of the port city Valletta in Malta, the defeats of French Navy in the Mediterranean encouraged a number of states to join the Second Coalition and go to war with France.
Unable to find Bonaparte, Nelson turned back across the Mediterranean, eventually reaching Sicily. While Nelson was returning westwards, Bonaparte reached Alexandria and stormed the city, capturing the coast and marching his army inland. Nelson returned to the Egyptian coast and ordered an immediate attack on the French. Fighting continued for the next two days, until all of the French ships had been captured, destroyed, or fled. At the Battle of the Nile, eleven French ships of the line and two frigates were eliminated, trapping Bonaparte in Egypt and changing the balance of power in the Mediterranean.
With the French Navy in the Mediterranean defeated, other nations were encouraged to join the Second Coalition and go to war with France. Portugal, the Kingdom of Naples, the Russian Empire, and the Ottoman Empire all subsequently deployed forces to the Mediterranean. The Russians and Turks participated in the blockade of Egypt and operations in the Adriatic Sea while the Portuguese joined the Siege of Malta, which was distantly conducted by Nelson from his lodgings in Naples.
Napoleon vs. the Second Coalition
The War of the Second Coalition (1798–1802) was the second war on revolutionary France by the European monarchies, led by Britain, Austria and Russia, and including the Ottoman Empire, Portugal and Naples. Their goal was to contain the spread of chaos from France.
Alerted to the political and military crisis in France, Napoleon returned from Egypt, leaving his army behind, and used his popularity and army support to mount a coup that made him First Consul, the head of the French government. Napoleon sent general Moreau to campaign in Germany and went himself to raise a new army at Dijon and march through Switzerland to attack the Austrian armies in Italy from behind. Narrowly avoiding defeat, he defeated the Austrians at the Battle of Marengo and reoccupied northern Italy. Moreau meanwhile invaded Bavaria and won a great battle against Austria at Hohenlinden. He continued toward Vienna and the Austrians sued for peace.
Napoleon Crossing the Alps by Jacques-Louis David (1800)
In one of the famous paintings of Napoleon, the Consul and his army are depicted crossing the Swiss Alps on their way to Italy. The daring maneuver surprised the Austrians and forced a decisive engagement at Marengo in 1800. Victory there allowed Napoleon to strengthen his political position back in France.
The Austrians negotiated the Treaty of Lunéville, basically accepting the terms of the previous Treaty of Campo Formio. In Egypt, the Ottomans and British invaded and finally compelled the French to surrender after the fall of Cairo and Alexandria. Britain continued the war at sea. A coalition of non-combatants including Prussia, Russia, Denmark, and Sweden joined to protect neutral shipping from Britain's blockade, resulting in Nelson's surprise attack on the Danish fleet in harbor at the Battle of Copenhagen. In December 1801, an expedition was sent to Saint-Domingue to quell the revolution that had started there in 1791 once and for all, but the blockade of the Caribbean island by the British fleet made the sending of reinforcements impossible.
In 1802, the British and French signed the Treaty of Amiens, ending the war. The treaty is generally considered to mark the transition between the French Revolutionary Wars and the Napoleonic Wars. The peace, however, did not last long. Great Britain had broken the Treaty of Amiens by declaring war on France in May 1803. In December 1804, an Anglo-Swedish agreement became the first step towards the creation of the Third Coalition. By April 1805, Britain had also signed an alliance with Russia. Austria had been defeated by France twice in recent memory and wanted revenge, so it joined the coalition a few months later.
