Arthur Dillon (1750–1794)

Arthur Dillon (1750–1794) was an Irish Catholic aristocrat born in England who inherited the ownership of a regiment that served France under the Ancien Régime during the American Revolutionary War and then the French First Republic during the War of the First Coalition. After serving in political positions during the early years of the revolution, he was executed in Paris as a royalist during the Reign of Terror in 1794.

Birth and origins
Arthur was born on 3 September 1750 at Bray Wick in Berkshire, England. He was the second son of Henry Dillon and his wife Charlotte Lee. His father was the 11th Viscount Dillon.

Arthur's mother was a daughter of George Lee, 2nd Earl of Lichfield. He had six siblings, who are listed in his father's article.

Colonel
On 25 August 1767, at the age of 16, he became colonel of Dillon's Regiment taking over from his father who had been absentee colonel for twenty years from 1747 to 1767 after the death of his uncle Edward at Lauffeld in 1747.

First marriage and children
At eighteen, Colonel Dillon married a first cousin once removed, Therese-Lucy de Rothe (1751–1782).

Arthur and Thérèse-Lucie had two children:
 * 1) George (who died at the age of two)
 * 2) Henriette-Lucy, or Lucie (by marriage, Henriette-Lucy, Marquise de La Tour du Pin Gouvernet), a memoiriste of the Revolutionary period and the Napoleonic era.

He was to become the grandfather of Arthur Dillon, also a military officer.

American Revolutionary War
In 1778 France entered the American Revolutionary War (1775–1783) on the American side. Colonel Dillon sailed with his regiment to the Caribbean to campaign against Britain under the command of D'Estaing. In 1779 he and his regiment fought at the Capture of Grenada against British forces under George Macartney. They landed on 2 July, and stormed the Hospital Hill which the British had chosen as the centre of their resistance. Arthur personally led one of the storm parties, his brother Henry led another. Macartney surrendered on 5 July. On 6 July 1779 a British fleet under Admiral John Byron appeared off the coast of the island and the naval engagement of the Battle of Grenada was fought. In September and October 1779 Dillon fought at the Siege of Savannah where he was promoted brigadier. Dillon and his regiment participated in the Invasion of Tobago, the Capture of Sint Eustatius, and the Siege of Brimstone Hill. With the victory at Brimstone Hill, Arthur Dillon was made Military Governor of Saint Kitts. After the Treaty of Paris, he became governor of Tobago.

Second marriage
His first wife having died, he married a wealthy French Creole widow from Martinique, Laure de Girardin de Montgérald, the Comtesse de la Touche, by whom he had six children, including Élisabeth Françoise 'Fanny' Dillon, later wife of Henri Gatien Bertrand. The Dillon Estate in Martinique produced sugar and later produced Dillon Rum.

Later life, death, and timeline
He returned to Paris to represent Martinique in the Estates General of 1789 as a democratic, reformist royalist.

Dillon assumed military duties at a very difficult time for noble officers of the old army. On 29 April 1792 his cousin Théobald Dillon was lynched by his own troops after a minor skirmish. After the Battle of Valmy, when Charles Dumouriez returned to the Belgian frontier with the greater part of the army, he detached Dillon with 16,000 troops to form the rump of the Army of the Ardennes around 1 October 1792. Two weeks later Dillon was called to Paris for questioning and was ultimately arrested on 1 July 1793 despite being stoutly defended by his aide-de-camp François Séverin Marceau-Desgraviers. He was condemned for alleged participation in a prison conspiracy and executed by guillotine on 13 April 1794. In his final moments he mounted the scaffold shouting, "Vive le roi!" (Long live the king).
