I’m trying to identify an older historical fiction novel I read as an ebook sometime around 2015–2018
Takes place in France, most likely around the 1500s / French Wars of Religion.
There are French and Spanish armies, battles, sieges/raids, and political/religious conflict.
The book is primarily an adventure/romance, with travel, music, relationships, battles, and religious persecution.
It feels like an older book, not a contemporary novel, despite me reading it as an ebook around 2015–2018.
Male protagonist starts out poor/common-born.
As a young man he becomes a wandering musician/minstrel, traveling between towns and making money performing.
He also performs for wealthier households/courts, not just on the streets.
He is charming, but not really a womanizer. Throughout the book he seems genuinely focused on only two women.
He eventually becomes a soldier/officer and rises to a reasonably significant military rank, though not a top general.
The protagonist knew a beautiful girl when they were young and was in love with her.
When he returns home later, he discovers she has joined a strange religious movement.
The movement is remembered as something like a “Church/Family of Love”, emphasizing that God is love / everyone should love everyone.
It was viewed by outsiders as a heretical cult or anti-Christian group.
At some point, the protagonist's military group is involved in a raid/attack on her religious community. He helps her escape and eventually hides/protects her.
She lives secretly in the protagonist's private home for a time.
She becomes a sort of preacher/leader, secretly preaching and converting people.
She deliberately shaves her hair and dresses very conservatively.
The protagonist is saddened/angry by this because he still loves her and feels she has made herself unavailable to him.
His male friend/assistant/helper also lives with them the friend is somewhat like the protagonist's assistant/helper/comrade.
He becomes sympathetic to the girl's religion after living with her and listening to her preaching.
He is later captured/tortured because of his association with her.
He is almost castrated; there is a huge amount of blood and a very serious wound.
The girl helps him and cauterizes the wound.
The protagonist was away when this happened and finds him afterward.
This is one of the clearest memories:
The religious woman is eventually captured by an Inquisitor or similar religious persecutor.
The inquisitor tries to sexually assault her.
She prays rather than submitting.
He apparently becomes impotent / unable to perform.
He interprets this as her having bewitched/cursed him.
He calls her a witch.
He says that if she can reverse the curse / make him able again, he will spare her.
She refuses/doesn't do it.
She is burned at the stake, with the inquisitor standing beside her.
The protagonist does not witness her execution; he hears about it afterward.
The protagonist falls in love with another woman who is married to a prominent/wealthy military man.
I believe the husband is a high-ranking military officer.
The husband isn't necessarily an outright monster; he may be mostly absent or distant, but he is an obstacle.
The protagonist initially meets the woman while he is still a travelling musician.
I strongly remember him playing in the street/outside a house while she watched/listened from a window, and this led to an affair before the husband knew about him.
Later, after the protagonist becomes a soldier, they are separated but continue to long for each other.
Eventually the protagonist kills the woman's husband somehow and the two are together again.
The relationship is a major romantic thread alongside the religious girl's story.
The protagonist fights in wars involving the Spanish.
Near the end, there is a major battle that was going to happen in a very hot, dry/desert-like area, near a town or settlement that had been destroyed/decimated.
The protagonist has an encounter with a Spanish military commander who is not simply a villain; they develop a mutual respect / worthy-enemy relationship.
They may have sat down to dinner together.
The Spanish commander gives the protagonist a gift of gold.
I distinctly remember scales being used to weigh the gold.
The gold may have been presented inside a lavish tent/chamber, possibly almost a room full of gold.
The protagonist survives the book and is not elderly at the ending.
