War of the First Coalition

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, Leopold II, Holy Roman Emperor, 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. In addition to the ideological differences between the French revolutionaries and the European monarchies, disputes continued over the status of Imperial estates in Alsace, 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. ==1792==

Invasion of the Austrian Netherlands 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. The French soldiers were insulted, hissed, even assaulted. The situation of the "Flanders Campaign" was alarming. 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. This motivated the revolutionary army and government to oppose the Prussian invaders by any means necessary, and led almost immediately to the overthrow of the King by a crowd which stormed the Tuileries Palace. Prussian progress '' by Léon Cogniet Brunswick's army, composed mostly of Prussian veterans, crossed into French territory on 19 August and easily took the fortresses of Longwy and Verdun. 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. Fronts in Italy and Germany 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. ==1793==

in December 1793 On 21 January the revolutionary government executed Louis XVI after a trial. 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. Introduction of conscription 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, 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. British land forces were defeated at the Battle of Hondschoote in September. ==1794==

A major victory against combined coalition forces at the Battle of Fleurus gained all of the Austrian Netherlands and the Rhineland for France. 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. The Prussians were slowly driven out of the eastern provinces and by the end of the year they had retired from any active part in the war. Against Spain, the French made successful incursions into both Catalonia and Navarre in the War of the Pyrenees. Actions in the West Indies 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. Prussian withdrawal Prussia had entered the war hoping for a quick territorial expansion, and was not prepared for an extended conflict as its position was weak from the start. While it had not actually entered battle, the Prussian army had been mobilized and then demobilized twice in the preceding two years - in face-offs against Austria in 1790 (in which 160,000 soldiers were assembled) and Russia in 1791 - which left the kingdom's treasury nearly empty after the third mobilization against France in 1792. The Prussians in 1792 suffered no major battlefield reversals but their poorly-planned march was devastated by disease and desertion; of the 42,000 Prussian soldiers who entered France as part of the coalition in that year (one of their two major thrusts along with the comparable force in the Low Countries), less than 20,000 recrossed the frontier and more than half of those were sick. A Prussian soldier who was later to live through the French invasion of Russia wrote that the Prussian retreat from Champagne in 1792 was perhaps a more terrible sight than even the wreck of the Grande Armée in 1812. Losses in the Low Countries in 1793 and 1794 added to the state's strain. Compounding all these issues was that the Prussian army was essentially split between two fronts: waging war against France in the west, and securing their gains in the Partitions of Poland (1792-1795) in the east (the Kościuszko Uprising would break out between the Second and Third Partitions). Recognizing that his kingdom could not afford to fight a long two-front war, Frederick William II sought to extricate his domains from the potentially disastrous conflict with the republic. He ceased any notable operations in 1794 and fully withdrew from the conflict by 1795. The Treaty of Basel, signed May 17 1795, costed Prussia its territories on the left bank of the Rhine but otherwise minimized losses; France agreed to withdraw from territories east of the Rhine and recognize Prussian gains in Poland and hegemony over the small north German states. While dominant in its sphere, Prussia left the war bankrupt and diplomatically isolated from its former allies; it would not attempt to war against France again until the War of the Fourth Coalition in 1806, after a long recuperation. . ==1795==

French capture of the Low Countries 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. Battle of Quiberon Britain attempted to reinforce the rebels in the Vendée by landing French Royalist troops at Quiberon, but failed, 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. Battle of Mainz 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. ==1796==

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. Rhine campaign 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. Invasion of Italy 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. End of the War of the Vendée The rebellion in the Vendée was also crushed in 1796 by Louis Lazare Hoche. Hoche's subsequent attempt to land a large invasion force in Munster to aid the United Irishmen was unsuccessful. ==1797==

On 2 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. Invasion of Great Britain On 22 February, a French invasion force consisting of 1,400 troops from 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. Austrian peace 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. ==See also==
