A knight and lord of Berny-en-Santerre and Les Pins[1] in the Vendômois, he became a colonel in the Gardes-Françaises, then succeeded La Fayette as commander of the National Guard in 1792.
[2] Galiot Mandat, lord of Aigrefoin, was received as king's secretary for provisions on 31 October 1572 on the resignation of Louis Guybert and his father.
The king confirmed his father in the land and seigneurie of Les Pins, in the north east of Touraine on 13 June 1727.
Antoine Galiot Mandat married Angélique Simone Boucher, daughter of a conseiller to the Parlement of Paris on 21 January 1758.
[8] In the pre-revolutionary period Marquis Antoine-Jean-Galiot de Mandat was well respected by his acquaintances in Les Pins, in the north east of Touraine, even by those who would soon lead Revolutionary efforts in the area.
Marie-Antoinette wanted to withdraw, but the National Guards begged her to do nothing and left them "to make these wits learn that we are not afraid of them".
[13] Antoine Galiot Mandat "always offered his head as a guarantee of the king's good intentions", but after the flight to Varennes and due to revolutionary propaganda he could no longer succeed in convincing all the national guards.
Because of the vote, the deputies who had provoked him were assaulted, beaten and threatened with death after the session had ended, until the National Guard came to their rescue.
According to Hippolyte Taine: "As to de Vaublanc, the main defender of La Fayette, having been attacked three times, he had taken the precaution not to go home but angry mobs showed up at his house, shouting that "eighty people will perish at their hands, and he would be first."
Twelve men who had climbed into his apartment and rummaged around also ransacked nearby houses, and, unable to catch him, looked for his family; they warned that if he returned to his home, he would be killed.
The assault on the Tuileries by Sans-culottes, Fédérés from the countryside and volunteers from Marseille under Charles Barbaroux was set for 10 August.
He even amassed the National Guard in the garden and placed cannons on Pont Neuf and near Tour Saint-Jacques, to stop the rioters' descent from faubourgs in the south and east.
[16] Mandat wrote to Villeneuve: Mr. Mayor, Your presence is necessary, appearances are threatening, and as magistrate of the people, you are better than anyone at making those who have lost their way listen to reason.
[21] Soon, at the circle on the Place de Grève, the bloody head of Mandat was detached from his body and raised into the air.
After Mandat's assassination, Antoine Joseph Santerre, a rich brewer from Faubourg Saint-Antoine, was appointed as the provisional commander of the insurgents.
The sumptuous Hôtel du Président Duret, 67 rue de Lille, belonged to him in 1792 and remained in his son's ownership until 1797, despite Mandat's assassination.
