Jean Thierry du Mont, comte de Gages

Jean Bonaventure Thierry du Mont, comte de Gages (Mons, now in Belgium, 27 December 1682 – Pamplona, Spain, 31 January 1753), Viceroy of Navarre, 1746–1753, a Knight of the Order of the Golden Fleece in 1745, was a Walloon born Spanish General who was awarded by King Philip V of Spain in 1745 the title of "Conde", "Count", of Gages, a village near Brugelette in Hainaut.

A lieutenant in the Walloon Guards, du Mont fought for the Spanish in many battles during the War of Spanish Succession, distinguishing himself in the Battle of Villaviciosa, and he also took part in the Spanish expedition to Oran (1732).

du Mont is best known for his role in the War of the Austrian Succession (1740–1748), a.k.a. King George's War in North America, and incorporating the War of Jenkins' Ear between Great-Britain and Spain.

The war in Italy was fought between a French-Spanish coalition, commanded by Infante Felipe, son of king Philip V of Spain, assisted between others by the French Marshal Maillebois, and du Mont as Captain General of the Spanish and Neapolitan armies on the one hand, and an Austrian-Sardinian coalition, backed by Great-Britain on the other hand.
