Context paragraphs:
French Renaissance literature: French Renaissance literature is, for the purpose of this article, literature written in French (Middle French) from the French invasion of Italy in 1494 to 1600, or roughly the period from the reign of Charles VIII of France to the ascension of Henry IV of France to the throne.  The reigns of Francis I (from 1515 to 1547) and his son Henry II (from 1547 to 1559) are generally considered the apex of the French Renaissance.  After Henry II's unfortunate death in a joust, the country was ruled by his widow Catherine de' Medici and her sons Francis II, Charles IX and Henry III, and although the Renaissance continued to flourish, the French Wars of Religion between Huguenots and Catholics ravaged the country.

Planned French invasion of Britain (1759): A French invasion of Great Britain was planned to take place in 1759 during the Seven Years' War, but due to various factors (including naval defeats at the Battle of Lagos and the Battle of Quiberon Bay) was never launched.  The French planned to land 100,000 French soldiers in Britain to end British involvement in the war.  The invasion was one of several abandoned attempts during the 18th century to invade the British Isles.

Battle of Quiberon Bay: The Battle of Quiberon Bay (known as Bataille des Cardinaux in French), was a decisive naval engagement fought on 20 November 1759 during the Seven Years' War between the Royal Navy and the French Navy.  It was fought in Quiberon Bay, off the coast of France near St. Nazaire.  The battle was the culmination of British efforts to eliminate French naval superiority, which could have given the French the ability to carry out their planned invasion of Great Britain.  A British fleet of 24 ships of the line under Sir Edward Hawke tracked down and engaged a French fleet of 21 ships of the line under Marshal de Conflans.  After hard fighting, the British fleet sank or ran aground six ships, captured one and scattered the rest, giving the Royal Navy one of its greatest victories, and ending the threat of French invasion for good.

Switzerland in the Napoleonic era: During the French Revolutionary Wars, the revolutionary armies marched eastward, enveloping Switzerland in their battles against Austria.  In 1798, Switzerland was completely overrun by the French and was renamed the Helvetic Republic.  The Helvetic Republic encountered severe economic and political problems.  In 1798 the country became a battlefield of the Revolutionary Wars, culminating in the Battles of Zürich in 1799.

Raid on Le Havre: The Raid on Le Havre was a two-day naval bombardment of the French port of Le Havre early in July 1759 by Royal Navy forces under Rear-Admiral George Rodney during the Seven Years' War, which succeeded in its aim of destroying many of the invasion barges being gathered there for the planned French invasion of Great Britain.

John Chambers White: Vice Admiral Sir John Chambers White, KCB (c. 1770–2 April 1845) was a prominent British Royal Navy officer of the early nineteenth century, who participated in a number of engagements during the Napoleonic Wars.  He achieved most of his fame in the late 1790s as the commander of HMS "Sylph", a small brig operating in Northern European waters.  White was able to capture a number of equivalent French, Spanish and Dutch vessels and on one occasion was instrumental in the destruction of a much larger French frigate by a British squadron.  In 1798 he was with the squadron that discovered the French invasion attempt on Ireland and acted as a messenger in the campaign to destroy the invasion force that ended at the Battle of Tory Island.  He was later flag captain for Sir John Borlase Warren and participated at the Action of 13 March 1806 and the destruction of the "Regulus" in 1814.  After the war, White largely retired, but retained several shore appointments and rose to the rank of vice-admiral.

Early Modern Switzerland: The early modern history of the Old Swiss Confederacy ("Eidgenossenschaft", also known as the "Swiss Republic" or "Republica Helvetiorum") and its constituent Thirteen Cantons encompasses the time of the Thirty Years' War (1618–1648) until the French invasion of 1798.

Pierre Hugues Victoire Merle: Pierre Hugues Victoire Merle (26 August 1766 – 5 December 1830) was a French general during the First French Empire of Napoleon.  He joined the French army as a private in 1781 but after the French Revolution, the pace of promotion quickened.  He was appointed a general officer in 1794 for distinguishing himself during the War of the Pyrenees.  After leading a brigade at Austerlitz in December 1805, he was promoted again.  His division was in the first wave of the 1808 invasion of Spain, which precipitated the Peninsular War.  In Spain, he led his division at Medina de Rioseco, Corunna, First and Second Porto, Bussaco, Sabugal, and Fuentes de Onoro.  After being sent home from Spain, Merle was assigned to lead a division in the French invasion of Russia.  He led his troops at First and Second Polotsk.  He embraced the Bourbon cause in 1814, retired from the army in 1816, and died at Marseilles in 1830.  Merle is one of the names inscribed under the Arc de Triomphe on Column 35.

French invasion of Switzerland: The French invasion of Switzerland (French: "Campagne d'Helvétie", German: "Franzoseneinfall") occurred from January until May 1798 as part of the French Revolutionary Wars.  The independent Old Swiss Confederacy collapsed, both by this foreign invasion and simultaneous internal revolts, termed the "Helvetic Revolution".  Its Ancien Régime institutions were abolished and replaced by the centralised pro-French Helvetic Republic.

Invasion of Dominica (1778): The Invasion of Dominica (7 September 1778) was a successful French invasion of the island of Dominica in the British West Indies, during the American Revolutionary War.  The action took place before British authorities in the Caribbean were aware that France had entered the war as an ally of the United States of America.  The French governor in the West Indies, François Claude Amour, marquis de Bouillé, was notified on 17 August that France was at war, and organized the invasion, infiltrating spies to rally sympathetic French-speaking Dominican support.
