About Augustin-Joseph de Mailly
Lived 1708 – 1794 (aged 85). Augustin-Joseph de Mailly was a French military officer, abbeville, bailiff and lieutenant général.
Augustin-Joseph de Mailly (5 April 1707 – 25 March 1794) was a French general, governor, and nobleman. He was one of the oldest persons to be guillotined during the French Revolution. De Mailly was marquis d'Haucourt and baron of Saint-Amand. In January 1744, he inherited the title of count of Mailly following the death of his cousin Louis de Mailly (1723–1743). At first a musketeer, he served in the gendarmerie (1733–1764) before rising rapidly through the ranks – brigadier on 20 February 1743, maréchal de camp on 1 May 1745, lieutenant-général on 10 May 1748, inspector general of cavalry and dragoons on 21 May 1749, and finally director-general of camps and armies. In disgrace, he was distanced from the court and therefore remained a lieutenant-Général for a very long time, before becoming commander in chief in Roussillon, where he was the originator of great building works and the renewal of the university and played a large rôle in French Freemasonry.
Made a chevalier du Saint-Esprit on 26 May 1776, he was made marshal of France on 13 June 1783 and due to his age was able to be governor of Abbeville, sénéchal and Grand bailli of Ponthieu not far from his lands and château. This Mailly, who fought in many battles of the wars of Louis XV, received from Louis XVI in 1790 command of one of the four armies decreed by the National Assembly (14th and 15th military divisions). This was a difficult task and he resigned on 22 June, when he learned of the king's flight to Varennes. On 10 August 1792, despite his old age, he fought on the side of the threatened French monarchy. Escaping the carnage that followed the capture of the palais des Tuileries and the September massacres, he was arrested in his château, then guillotined in 1794 at Arras, aged 86 – on the scaffold he cried "I remain faithful to my king, as my ancestors have always been".

Life
Port-Vendres Louis XVI, true restorer of the French war and commercial navy, entrusted General de Mailly with the installation of a powerful and fortified port which would finally be able to ensure regular traffic with the whole of Europe, from Spain to Sweden, Scotland to Italy, the Catalan coast to the East, to the Barbary ports, and even as far away as India and the Americas. Mailly restructured Port-Vendres, which he wanted like Perpignan, to be the ideal representation of a Masonic city. He built a deep port there, sheltered from the winds. In addition to the modern port, in fifteen years (1770 - 1785), he completed the city, outlines and pierces a few small streets, builds new dwellings on a uniform plan, corrects alignments, builds quays and convenient landing stages. To mark the rebirth of Port-Vendres with a symbol, Louis XVI allowed the province to erect to his glory the first monument erected in France in his honor, the obelisk of Port-Vendres. In 1775 he reinforced the fortifications at the entrance to the port of Port-Vendresby building the Mailly Redoubt opposite the Fanal Redoubt: built by Vauban between 1673 and 1700 to defend the port.
On 2 October 1753, Marshal de Noailles, in quarrel with Mailly, succeeded in having him dismissed from his command. In November 1753, Jean-Baptiste de Machault d'Arnouville obtains the exile of Mailly from the king. On 1 March 1754, the king rebuked the count of Mailly d'Haucourt for having spread too much his memory that René Louis de Voyer de Paulmy d'Argenson considers apologetic. Mailly must return to his land. His mistress, the Marquise de Blanes and her husband, spoke out against the government. They were also outlawed. Mailly's disgrace did not last long, because he was responsible for going to Spain to compliment the Infanta Marie-Thérèse-Raphaëlle de Bourbon on behalf of the king.
10 August 1792 Marshal de Mailly refused to emigrate; the idea of the king being abandoned in Paris without the clergy and nobility to him was a revolting absurdity. In 1790, Louis XVI gave him the command of one of four armies decreed by the National Assembly and that of the 14th and 15th military divisions. The assembly demanded a civic oath, and Marshal de Mailly resigned.
On 9 August, when he learned of the dangers surrounding the royal family, he went to the Tuileries Palace. He was entrusted by the King with the command of the troops who would defend the Tuileries the next day, 10 August 1792. During the attack, the defense is swept away. Mailly escaped the massacre and received help to escape.
Arrest and execution On 25 March 1794, de Mailly was executed by guillotine, at the time of his execution he was the oldest person to be executed.
