French Revolutionary Wars: The Battle of the Nile concludes in a British victory.

The Battle of the Nile (also known as the Battle of Aboukir Bay; French: Bataille d'Aboukir) was a major naval battle fought between the British Royal Navy and the Navy of the French Republic at Aboukir Bay on the Mediterranean coast off the Nile Delta of Egypt from the 1st to the 3rd of August 1798. The battle was the climax of a naval campaign that had raged across the Mediterranean during the previous three months, as a large French convoy sailed from Toulon to Alexandria carrying an expeditionary force under General Napoleon Bonaparte. The British fleet was led in the battle by Rear-Admiral Sir Horatio Nelson; they decisively defeated the French under Vice-Admiral Franois-Paul Brueys d'Aigalliers.

Bonaparte sought to invade Egypt as the first step in a campaign against British India, as part of a greater effort to drive Britain out of the French Revolutionary Wars. As Bonaparte's fleet crossed the Mediterranean, it was pursued by a British force under Nelson who had been sent from the British fleet in the Tagus to learn the purpose of the French expedition and to defeat it. He chased the French for more than two months, on several occasions missing them only by a matter of hours. Bonaparte was aware of Nelson's pursuit and enforced absolute secrecy about his destination. He was able to capture Malta and then land in Egypt without interception by the British naval forces.

With the French army ashore, the French fleet anchored in Aboukir Bay, 20 miles (32 km) northeast of Alexandria. Commander Vice-Admiral Franois-Paul Brueys d'Aigalliers believed that he had established a formidable defensive position. The British fleet arrived off Egypt on 1 August and discovered Brueys's dispositions, and Nelson ordered an immediate attack. His ships advanced on the French line and split into two divisions as they approached. One cut across the head of the line and passed between the anchored French and the shore, while the other engaged the seaward side of the French fleet.

Trapped in a crossfire, the leading French warships were battered into surrender during a fierce three-hour battle, although the centre of the line held out for a while until more British ships were able to join the attack. At 22:00, the French flagship Orient exploded which prompted the rear division of the French fleet to attempt to break out of the bay. With Brueys dead and his vanguard and centre defeated, only two ships of the line and two frigates escaped from a total of 17 ships engaged.

The battle reversed the strategic situation between the two nations' forces in the Mediterranean and entrenched the Royal Navy in the dominant position that it retained for the rest of the war. It also encouraged other European countries to turn against France, and was a factor in the outbreak of the War of the Second Coalition. Bonaparte's army was trapped in Egypt, and Royal Navy dominance off the Syrian coast contributed significantly to the French defeat at the siege of Acre in 1799 which preceded Bonaparte's abandonment of Egypt and return to Europe. Nelson had been wounded in the battle, and he was proclaimed a hero across Europe and was subsequently made Baron Nelsonalthough he was privately dissatisfied with his rewards. His captains were also highly praised and went on to form the nucleus of the legendary Nelson's Band of Brothers. The legend of the battle has remained prominent in the popular consciousness, with perhaps the best-known representation being Felicia Hemans' 1826 poem Casabianca.

The French Revolutionary Wars (French: Guerres de la Révolution française) were a series of sweeping military conflicts lasting from 1792 until 1802 and resulting from the French Revolution. They pitted France against Britain, Austria, Prussia, Russia, and several other monarchies. They are divided in two periods: the War of the First Coalition (1792–97) and the War of the Second Coalition (1798–1802). Initially confined to Europe, the fighting gradually assumed a global dimension. After a decade of constant warfare and aggressive diplomacy, France had conquered territories in the Italian Peninsula, the Low Countries and the Rhineland in Europe and abandoned Louisiana in North America. French success in these conflicts ensured the spread of revolutionary principles over much of Europe.

As early as 1791, the other monarchies of Europe looked with outrage at the revolution and its upheavals; and they considered whether they should intervene, either in support of King Louis XVI, to prevent the spread of revolution, or to take advantage of the chaos in France. Austria stationed significant troops on its French border and together with Prussia, issued the Declaration of Pillnitz, which threatened severe consequences should anything happen to King Louis XVI and Queen Marie-Antoinette. After Austria refused to recall its troops from the French border and to back down on the perceived threat of using force, France declared war on Austria and Prussia in the spring of 1792; both countries responded with a coordinated invasion that was eventually turned back at the Battle of Valmy in September. This victory emboldened the National Convention to abolish the monarchy. A series of victories by the new French armies abruptly ended with defeat at Neerwinden in the spring of 1793. The French suffered additional defeats in the remainder of the year and these difficult times allowed the Jacobins to rise to power and impose the Reign of Terror to unify the nation.

In 1794, the situation improved dramatically for the French as huge victories at Fleurus against the Austrians and at the Black Mountain against the Spanish signaled the start of a new stage in the wars. By 1795, the French had captured the Austrian Netherlands and the Dutch Republic. The French also put Spain and Prussia out of the war with the Peace of Basel. A hitherto unknown general named Napoleon Bonaparte began his first campaign in Italy in April 1796. In less than a year, French armies under Napoleon decimated the Habsburg forces and evicted them from the Italian peninsula, winning almost every battle and capturing 150,000 prisoners. With French forces marching towards Vienna, the Austrians sued for peace and agreed to the Treaty of Campo Formio, ending the First Coalition against the Republic.

The War of the Second Coalition began in 1798 with the French invasion of Egypt, headed by Napoleon. The Allies took the opportunity presented by the French effort in the Middle East to regain territories lost from the First Coalition. The war began well for the Allies in Europe, where they gradually pushed the French out of Italy and invaded Switzerland – racking up victories at Magnano, Cassano and Novi along the way. However, their efforts largely unraveled with the French victory at Zurich in September 1799, which caused Russia to drop out of the war. Meanwhile, Napoleon's forces annihilated a series of Egyptian and Ottoman armies at the battles of the Pyramids, Mount Tabor and Abukir. These victories in Egypt further enhanced Napoleon's popularity back in France, and he returned in triumph in the fall of 1799, though the Egyptian Campaign ultimately ended in failure. Furthermore, the Royal Navy had won the Battle of the Nile in 1798, further strengthening British control of the Mediterranean and weakening the French Navy.

Napoleon's arrival from Egypt led to the fall of the Directory in the Coup of 18 Brumaire, with Napoleon installing himself as Consul. Napoleon then reorganized the French army and launched a new assault against the Austrians in Italy during the spring of 1800. This brought a decisive French victory at the Battle of Marengo in June 1800, after which the Austrians withdrew from the peninsula once again. Another crushing French triumph at Hohenlinden in Bavaria forced the Austrians to seek peace for a second time, leading to the Treaty of Lunéville in 1801. With Austria and Russia out of the war, Britain found itself increasingly isolated and agreed to the Treaty of Amiens with Napoleon's government in 1802, concluding the Revolutionary Wars. However, the lingering tensions proved too difficult to contain, and the Napoleonic Wars began over a year later with the formation of the Third Coalition, continuing the series of Coalition Wars.
