Jean VI d'Aumont (1522-1595) was a soldier and Marshal of France. He served as Marshal under Henri III, campaigning against the Protestants in 1585. He would not however conduct the campaign with much enthusiasm, and after clamour at court he would be replaced by Anne de Joyeuse He playing a key role in the Day of the Barricades and Assassination of the Duke of Guise (1588). Upon the assassination of Henri III in 1589, he would transfer his loyalties to the Protestant Navarre and would campaign for him in Burgundy, Maine and Brittany against the Duke of Mercœur. He was also granted the office of governor of Dauphiné, upon it being vacated in 1592. It would be whilst fighting in Brittany in 1595, that he would be killed.
Aumont was from an old noble family, which is recorded as far back as the thirteenth century.
In 1585 Aumont was granted command of an army by Henri and sent to campaign in Auvergne and Languedoc against the forces of Navarre. He was among those accused of lethargy in the conduct of the campaign against the Protestants by those at court, as such Anne de Joyeuse was sent to take over leadership in Auvergne.
See main article: Day of the Barricades. Aumont was among those nobles who in 1588, was less concerned with matters of the Ligue than the duels of Les Mignons and affairs of the court. During the Day of the Barricades the angry population demanded the removal of the French and Swiss troops in the capital. The king relented, and instructed O, Alphonse, Biron and Aumont to remove the soldiers from the city. Unable to tolerate the domination of the Guise over him that the day of the Barricades had brought about, the king decided to have them assassinated.
While staying at Blois in December the king met with Aumont, Rambouillet and d'Ornano in a secret council, at which they agreed that Guise would have to be killed. Having worked out the specifics of the plan, the king informed Guise of his intention to retreat to his château at La Noue for Christmas and his desire that the whole council meet prior to departing. Guise duly attended, but was puzzled by the presence of many nobles who did not usually attend council, among them Aumont. He sought an explanation but none was provided for the Marshals presence. After the meeting was concluded Guise was invited into a side chamber with the king, where many nobles stabbed him to death. The Cardinal of Guise, and the Archbishop of Lyons who had remained in the chamber heard the commotion, and attempted to rush in to support their kinsmen and ally. Aumont put his hand on his sword, and as an officer of the crown forbade them, and any others in the room from moving on pain of death.
The king was now unable to avoid open war with the ligue. To this end Aumont was tasked to lead in March 1589 with leading the main body of the loyalist army. His forces headed out from Tours to make an attempt to besiege Le Mans. In April his forces found themselves in Angers and were able to hold off a ligue attempt on the town. Shortly thereafter in light of the dire situation in the country Henri made a rapprochement with Navarre and the two allied against the ligue.
With the king's death a short while later, Aumont was among the nobility that recognised Navarre as king, even prior to his conversion to Catholicism. Aumont was among the nobles who attended the heavily guarded funeral for the king in Compiègne as the civil war continued to rage.
Aumont campaigned in Burgundy for Navarre in 1591, sweeping all before him in the countryside. He was however unable to make inroads into the ligue bastions of Auxerre and Mâcon. In 1592 Navarre appointed him as governor of Dauphiné, replacing Montpensier, he would hold this office until his death. The same year he campaigned in Maine seeking to reverse the royal loss at the Battle of Craon, he captured Mayenne and would take Laval in 1594.[1] In 1593 his campaigning moved to Brittany, where, with the support of Conti he advanced on the Duke of Mercœur. To this end he was in command of 7000 soldiers, which were entirely mercenary in composition. It was during fighting in Brittany that he died in 1595.
