War of the Reunions

The War of the Reunions (1683–84) was a short conflict between France and Spain and its allies. It was fueled by the long-running desire of Louis XIV to conquer new lands, many of them comprising part of the Spanish Netherlands, along France's northern and eastern borders. The war was, in some sense, a continuation of the territorial and dynastic aims of Louis XIV as manifested in the War of Devolution and the Franco–Dutch War.

Background
The treaties ending the War of Devolution (the Treaty of Aix-la-Chapelle [1668]) and the Franco–Dutch War (the Treaty of Nijmegen [1678]), as well as the Treaty of Westphalia of 1648 (which ended the Thirty Years War), ceded a number of towns to France. By tradition, when a town changed hands so did the surrounding rural areas, which provided it with food and other such supplies. Often, the borders of these dependent regions were ill-defined. Thus Louis and his court, beginning in 1670, introduced several Chambers of Reunion that would investigate whether France had been granted all the territory it had been owed. The Chambers of Reunion, loyal to the king, ruled after a review of conflicting medieval documents that a number of outlying areas should be awarded to France. These territories generally consisted of small towns and villages, and for the most part Louis's annexations went unopposed.

The territory seized mainly came from the Spanish Netherlands and the western parts of the Holy Roman Empire, especially Alsace. Two of these territories seized by Louis as part of the Reunions were Strasbourg and Luxembourg. Officially, Strasbourg was intended to remain a neutral and independent city. However, this left large rural lands under Louis's control that were unprotected by major garrison towns, because Louis' advisors believed that as long as Strasbourg remained "independent" Alsace would never be secure from attack. Indeed, the bridge over the Rhine at Strasbourg had been used repeatedly by the Imperial (Holy Roman Empire) forces. Three times during the recent Franco-Dutch War Strasbourg had served as a gateway for Imperial invasions into Alsace. Thus, Strasbourg endangered Louis's newly annexed territories in Alsace, just as the great fortress of Luxembourg dominated the other regions Louis had annexed from the Spanish Netherlands. In 1681 Strasbourg, then a "so-called "independent" city in Holy Roman Empire, was annexed after Louis surrounded the city with overwhelming force. Louis marched into the city on 30 September 1681.  Louis also ordered Marshal Louis-François Boufflers to surround and begin an artillery and mortar barrage of Luxembourg.

The summer of 1683 was the peak of War of the Holy League, in which the eastern flank of the Holy Roman Empire went under the greatest ever offensive by Ottoman Empire. This war on the eastern front of the Holy Roman Empire, broke the momentum of Louis' confrontation with the Empire over Luxembourg. Louis decided that it would be impolitic for him to attack another Christian kingdom while that kingdom were under attack from the infidel Turk. Accordingly in March 1682, Louis ordered a halt to the bombardment of Luxembourg and withdrew his troops. On 12 September 1683, combined Imperial and German troops defeated the Turks right under the walls of Vienna. This was the high-water mark of Turkish expansion. The defeat before the walls of Vienna was a crucial turning point for Europe. The mistique and prestige of the Ottoman Turks was broken in the eyes of Europe. Turkey would never again be on the offensive in Europe and would be on the defensive until the downfall of the Ottomans in 1908.

War
As the Ottoman threat stalled before Vienna, the Hapsburgs were able to turn their attentions to the west. Luxembourg's resistance to the demands of the French Reunion claims and their refusal to fall to the French army caused war to break out. The Spain declared war on France on 26 October 1683. A French army under the Duke of Humières surrounded the town of Courtrai on the night of 3–4 November 1683. The fortress at Courtrai fell on 6 November 1683. Humières, then, advanced on Dixmude which surrendered without a fight on 10 November 1683.

A French army under Marshal François-Joseph, Créqui bombarded Luxembourg with 3,000 to 4,000 mortar shells between 22–26 December 1683 and the withdrew from the city. However, the real siege of Luxembourg began the next spring when assisted by his technical expert on siege warfare, Sébastien le Prestre de Vauban, Louis once again surrounded the large fortress at Luxembourg on 29 April 1684. The fortress was defended by 2,500 men and they fought on against the French army until 3 June 1684 when they surrendered. Spanish forces in the Netherlands, backed by the Holy Roman Empire, continued to fight the French until a final treaty in the war was reached at Treaty of Ratisbon on 15 August 1684. The Treaty of Ratisbon was really just a truce and, thus, France continued to hold all the territory she had taken during the war, including Strasbourg and Luxembourg. France's subsequent actions taken after the war were intended merely to make the truce into a real permanent treaty.

Despite its relative brevity, the War of the Reunions developed a reputation for being an especially bloody conflict. Louis XIV and his military advisors designed a campaign of violent reprisals in an effort to influence public opinion, with the aim of pressuring enemy officials to surrender. During one battle Louvois ordered the comte de Montal to burn twenty villages near Charleroi because the Spanish previously destroyed two barns on the outskirts of two French villages, and he insisted that not a single house should remain standing in the twenty villages.

The Republic of Genoa had a long standing relationship with Spain. Indeed, Genoese bankers and financial houses—the Centurioni, the Palavicini and the Vivaldi families —had since the sixteenth century been loaning money to the Spanish government. However, Genoese involvement in the recent war between Spain and France had been rather limited—allowing the Spanish to recruit mercenary soldiers on Genoese territory and building some galleys for the Spanish navy. However, even this limited involvement was too much for the French to bear. As a punishment for these indescretions and for allowing the Spanish troops to use the port at Genoa, a French fleet under the command of Abraham Duquesne sailed from France's great Mediterranean naval base of Toulon to Genoa on 5 May 1684 and began a bombardment of Genoa on 17 May 1684. The bombardment of Genoa lasted for the next 12 days in May 1684 with the exception of a reprieve lasting from 22 May until 25 May 1684 to allow for negotiations on a peace to be conducted. When these negotiqtions broke fown the bombardment resumed and continued until 28 May 1684. In all, the French showered 13,300 bombs on Genoa, destroying about two-thirds of the city.

Peace and treaty
While Louis refused to send aid to the Empire and even dispatched envoys to secretly encourage the Ottomans, contemporary accounts indicate that it would be unseemly for him to continue fighting the Empire on its western border. Thus, Louis agreed to the Truce of Ratisbon, guaranteeing twenty years of peace between France and the Empire and asking his first cousin, Charles II of England, to arbitrate the disputed border claims.

Aftermath of war
The War of the Reunions, like its immediate continental predecessors, failed to resolve the festering conflict between the French Bourbon Dynasty and the Spanish and Austrian branches of the Habsburg Dynasty. This brief though brutal conflict was one of the precursors to the lengthier Nine Years' War.
