The War of the First Coalition (French: Guerre de la Première Coalition) was a set of wars that several European powers fought between 1792 and 1797, initially against the constitutional Kingdom of France and then the French Republic that succeeded it.^[18] They were only loosely allied and fought without much apparent coordination or agreement; each power had its eye on a different part of France it wanted to appropriate after a French defeat, which never occurred.^[19]

Relations between the French revolutionaries and neighbouring monarchies had deteriorated following the Declaration of Pillnitz in August 1791. Eight months later, following a vote of the revolutionary-led Legislative Assembly, France declared war on Austria on 20 April 1792; Prussia, having allied with Austria in February, declared war on France in June 1792. In July 1792, an army under the Duke of Brunswick and composed mostly of Prussians joined the Austrian side and invaded France. The capture of Verdun (2 September 1792) triggered the September massacres in Paris. France counterattacked with the victory at Valmy (20 September) and two days later the Legislative Assembly proclaimed the French Republic.

Subsequently, these powers made several invasions of France by land and sea, in association with Prussia and Austria attacking from the Austrian Netherlands and the Rhine, and Great Britain supporting revolts in provincial France and laying siege to Toulon in October 1793. France suffered reverses (Battle of Neerwinden, 18 March 1793) and internal strife (War in the Vendée) and responded with draconian measures. The Committee of Public Safety was formed (6 April 1793) and the levée en masse drafted all potential soldiers aged 18 to 25 (August 1793). The new French armies counterattacked, repelled the invaders, and advanced beyond France.

The French established the Batavian Republic as a sister republic (May 1795) and gained Prussian recognition of French control of the Left Bank of the Rhine by the first Peace of Basel. With the Treaty of Campo Formio, Austria ceded the Austrian Netherlands to France and Northern Italy was turned into several French sister republics. Spain made a separate peace accord with France (Second Treaty of Basel) and the French Directory annexed more of the Holy Roman Empire.

North of the Alps, Archduke Charles, Duke of Teschen defeated the invading armies during the Rhine campaign, but Napoleon Bonaparte succeeded against Sardinia and Austria in northern Italy (1796–1797) near the Po Valley, culminating in the Peace of Leoben and the Treaty of Campo Formio (October 1797). The First Coalition collapsed, leaving only Britain in the field fighting against France.

As early as 1791, other monarchies in Europe were watching the developments in France with alarm, and considered intervening, either in support of Louis XVI or to take advantage of the chaos in France. The key figure, the Holy Roman Emperor Leopold II, brother of the French Queen Marie Antoinette, had initially looked on the Revolution calmly. He became increasingly concerned as the Revolution grew more radical, although he still hoped to avoid war.

On 27 August 1791, Leopold and King Frederick William II of Prussia, in consultation with émigré French nobles, issued the Declaration of Pillnitz, which declared the concern of the monarchs of Europe for the well-being of Louis and his family, and threatened vague but severe consequences if anything should befall them. Although Leopold saw the Pillnitz Declaration as a way of taking action that would enable him to avoid actually doing anything about France, at least for the moment, Paris saw the Declaration as a serious threat and the revolutionary leaders denounced it.^[20]

In addition to the ideological differences between France and the monarchical powers of Europe, disputes continued over the status of Imperial estates in Alsace,^[20] and the French authorities became concerned about the agitation of émigré nobles abroad, especially in the Austrian Netherlands and in the minor states of Germany. In the end, France declared war on Austria first, with the Assembly voting for war on 20 April 1792, after the presentation of a long list of grievances by the newly appointed foreign minister Charles François Dumouriez, who sought a war which might restore some popularity and authority to the King.^[21]

Dumouriez prepared an invasion of the Austrian Netherlands, where he expected the local population to rise against Austrian rule. However, the revolution had thoroughly disorganized the French army, which had insufficient forces for the invasion. Its soldiers fled at the first sign of battle, deserting en masse, in one case murdering General Théobald Dillon.^[21] The French soldiers were insulted, hissed, even assaulted. The situation of the "Flanders Campaign" was alarming.^[22]

While the revolutionary government frantically raised fresh troops and reorganized its armies, an allied army under Charles William Ferdinand, Duke of Brunswick assembled at Koblenz on the Rhine. The invasion commenced in July 1792. The Duke then issued a declaration on 25 July 1792, which had been written by the brothers of Louis XVI, that declared his [Brunswick's] intent to restore the King of France to his full powers, and to treat any person or town who opposed him as rebels to be condemned to death by martial law.^[21] This motivated the revolutionary army and government to oppose the Prussian invaders by any means necessary,^[21] and led almost immediately to the overthrow of the King by a crowd which stormed the Tuileries Palace.^[23]

Brunswick's army, composed mostly of Prussian veterans, crossed into French territory on 19 August and easily took the fortresses of Longwy and Verdun.^[24] But at the Battle of Valmy on 20 September 1792 they came to a stalemate against Dumouriez and Kellermann in which the highly professional French artillery distinguished itself. Although the battle was a tactical draw, it bought time for the revolutionaries and gave a great boost to French morale. Furthermore, the Prussians, facing a campaign longer and more costly than predicted, decided against the cost and risk of continued fighting and determined to retreat from France to preserve their army.^[18]

Meanwhile, the French had been successful on several other fronts, occupying the Duchy of Savoy and the County of Nice until the Massif de l'Authion, while General Custine invaded Germany, capturing Speyer, Worms and Mainz along the Rhine, and reaching as far as Frankfurt. Dumouriez went on the offensive in the Austrian Netherlands once again, winning a great victory over the Austrians at Jemappes on 6 November 1792, and occupying the entire country by the beginning of winter.^[18]

On 21 January the revolutionary government executed Louis XVI after a trial.^[25] This united all European governments, including Spain, Naples & Sicily, and the Netherlands against the Revolution. France declared war against Britain and the Netherlands on 1 February 1793 and soon afterwards against Spain. In the course of the year 1793 the Holy Roman Empire (on 23 March), the kings of Portugal and Naples, and the Grand Duke of Tuscany declared war against France. Thus the First Coalition was formed.^[18]

France introduced a new levy of hundreds of thousands of men, beginning a French policy of using levée en masse (mass conscription) to deploy more of its manpower than the other states could,^[18] and remaining on the offensive so that these mass armies could commandeer war material from the territory of their enemies. The Girondin faction of the French government sent Citizen Genet to the United States to encourage them to enter the war on France's side. The newly formed nation refused, and the Washington administration's 1793 Proclamation of Neutrality threatened legal action against any citizen providing assistance to any side in the conflict.

After a victory in the Battle of Neerwinden in March, the Austrians suffered twin defeats at the battles of Wattignies and Wissembourg.^[26] British land forces were defeated at the Battle of Hondschoote in September.^[26]

1794 brought increased success to the revolutionary armies. A major victory against combined coalition forces at the Battle of Fleurus gained all of the Austrian Netherlands and the Rhineland for France.^[26] Although the British navy maintained its supremacy at sea, it was unable to support effectively any land operations after the fall of the Belgian provinces.^[27] The Prussians were slowly driven out of the eastern provinces^[26] and by the end of the year they had retired from any active part in the war.^[27] Against Spain, the French made successful incursions into both Catalonia and Navarre^[27] in the War of the Pyrenees.

Action extended into the French colonies in the West Indies. A British fleet occupied Martinique, St. Lucia, and Guadeloupe, although a French fleet arrived later in the year and recovered the latter by ousting the invaders.^[28]

After seizing the Low Countries in a surprise winter attack, France established the Batavian Republic as a puppet state. Even before the close of 1794 Prussia retired from any active part in the war, and on 5 April 1795 King Frederick William II concluded with France the Peace of Basel, which recognized France's occupation of the left bank of the Rhine. The new French-dominated Dutch government bought peace by surrendering Dutch territory to the south of that river. A treaty of peace between France and Spain followed in July. The grand duke of Tuscany had been admitted to terms in February. The coalition thus fell into ruin and France proper would be free from invasion for many years.^[29]

Britain attempted to reinforce the rebels in the Vendée by landing French Royalist troops at Quiberon, but failed,^[30] and attempts to overthrow the government in Paris by force were foiled by the military garrison led by Napoleon Bonaparte, leading to the establishment of the Directory.^[31][32]

On the Rhine frontier, General Pichegru, negotiating with the exiled Royalists, betrayed his army and forced the evacuation of Mannheim and the failure of the siege of Mainz by Jourdan.^[33]

The French prepared a great advance on three fronts, with Jourdan and Jean Victor Marie Moreau on the Rhine and the newly promoted Napoleon Bonaparte in Italy. The three armies were to link up in Tyrol and march on Vienna.

In the Rhine campaign of 1796, Jourdan and Moreau crossed the Rhine river and advanced into Germany. Jourdan advanced as far as Amberg in late August while Moreau reached Bavaria and the edge of Tyrol by September. However Jourdan was defeated by Archduke Charles, Duke of Teschen and both armies were forced to retreat back across the Rhine.^[33][34]

Napoleon, on the other hand, 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 under Johann Peter Beaulieu, Dagobert Sigmund von Wurmser and József Alvinczi while continuing the siege.^[34][33]

The rebellion in the Vendée was also crushed in 1796 by Louis Lazare Hoche.^[34] Hoche's subsequent attempt to land a large invasion force in Munster to aid the United Irishmen was unsuccessful.^[28]

On 2 February Napoleon finally captured Mantua,^[35] 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.^[35]

On 22 February, a French invasion force consisting of 1,400 troops from the La Legion Noire (The Black Legion) under the command of Irish American Colonel William Tate landed near Fishguard in Wales. They were met by a quickly assembled group of around 500 British reservists, militia and sailors under the command of John Campbell, 1st Baron Cawdor. After brief clashes with the local civilian population and Lord Cawdor's forces on 23 February, Tate was forced into an unconditional surrender by 24 February. This would be the only battle fought on British soil during the Revolutionary Wars.

Austria signed the Treaty of Campo Formio in October,^[35] ceding Belgium to France and recognizing French control of the Rhineland and much of Italy.^[34] 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.
