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 . Life . 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 . During the War of Polish Succession ( 1733 - 1738 ) , Spain had retrieved Naples andSicily , but failed to retake Milan and Parma . Now King Philip V , but mostly his second wife , energetic and ambitious former Italian Princess Elizabeth of Parma , wanted to retake all former Spanish territories in Italy for her son King Charles VII of Naples and Sicily . On February 8 , 1743 , du Mont defeated the Austrians and Sardinians at the Battle of Campo Santo , followed later from September to December 1745 by the 2nd Battle of Milan , 1745 which was widely considered a victory in Madrid . When Marshal Saxe defeated the British Army at Battle of Fontenoy in 1745 and overran the Low Countries , the Spanish Crown granted du Mont the county of Gages , near his birthplace until then occupied by the Austrians since 1713 . Meanwhile , " Juan de Gages " as he was usually called by his Spanish - Neapolitan soldiers , fought against the Austrians in the Milanese and Piedmont , Parma and Piacenza supported by the Genoese . Towards the end of 1745 Alexandria and Milan were also conquered , but then the chances of war turned . The Austrians took back Milan on 18 March 1746 and the Spanish - Neapolitan army under the count of Gages was beaten by the Austrians at the Battle of Piacenza ( 16 June 1746 ) , and the Battle of Tidone ( 10 August 1746 ) . Enough was enough , moneywise and blood wise . The new King of Spain , Ferdinand VI of Spain , the half brother of King Charles of Naples and Sicily ( later also King of Spain under the name Charles III of Spain ) , was probably well advised to stop all these adventurous and costly wars . Juan Buenaventura Thierry du Mont was after the war awarded the title of Viceroy of Navarre in 1749 . Some 4 years later he died there , in Pamplona , 1753 . He was much interested in paving adequately many roads used during many centuries taking particular care on any Roman remains in or around such roads . His tomb was moved several times , specially during the Napoleonic Wars to avoid desecration by the French Imperial soldiers . After two or more moves , his mausoleum was placed in the cloister of the Pamplona Cathedral , where it can be seen today .
