Unlike his older brothers he could not countenance service to a Protestant king upon the death of Henri and defected to the ligue.

By 1595 he had returned to the royalist cause, and was rewarded by the, now Catholic Henri IV with appointment as a chevalier of the Ordre du Saint-Esprit.

[4] They had served the kings of France going back to Jean de Balsac, who fought under Charles VII.

[7] Entraguet hired the architect Baptise Androuet du Cerceau to renovate his Château de Tournanfy.

[8] Alongside fellow classmate the duke of Anjou, brother to the king, Entraguet studied at the Collège de Navarre.

[10] Notably this involved his participation in the Anjou led 1573 siege of La Rochelle, the city having risen up in response to the Massacre of Saint Bartholomew.

On route he passed through the city of Frankfurt where the party encountered a group of Walloon soldiers who angrily blamed the duke and his entourage of involvement in the Massacre of Saint Bartholomew.

[15] Entraguet would find himself elevated to the honour of gentilhomme de la chambre du roi in December 1574.

Entraguet turned to the house of Lorraine as an alternative network of support after his alienation from the king, however this was less a desire to enter an opposing political alliance, and more a return to the default arrangement his family had enjoyed in the previous generation.

[18] At the Estates General called as a result of the Peace of Monsieur, Entraguet held a duel with Georges Babou de La Bourdaisière, a favourite of the king's brother Alençon In April 1578, the favourites of Henri, deprived of their regular enemy the duke of Alençon by his flight from court, turned their attentions to those men close to the duke of Guise.

[19] Alternative explanations for the duel include a dispute over a game of Jeu de Paume and over the right to court a woman.

[23] Henri resisted however engaging in a prosecution against Entraguet for the death of his favourites, as this would reveal the responsibility of Caylus for arranging the duel and further would be an attack on the Lorraine family who he could not afford to move against.

[29] Shortly after the duel, the Lorraine family staged a grand departure from the court, as an expression of their displeasure at what had transpired.

[18] The king was keen to resecure the loyalty of Entraguet's elder brother, and as such tasked Épernon to bring him back into the royal fold.

After a month of efforts Entraguet convinced Entragues to come to meet with the king and accept a deal for his return to favour.

[30] After having resolved to assassinate the duke of Guise in 1588, Entraguet played the role of agent of the king in the plans for its realisation.

[32] In 1594, shortly after his triumphant acquisition of Paris from the ligue, Henri wrote to Entraguet, urging him to hurry to court so that he might witness the majesty of the king's triumph over the kingdom.
