Characters who died fighting for the King

"You told me your sons died fighting for the king."

"And so they did. The rightful king, Daemon Blackfyre. The King Who Bore the Sword." -The Sworn Sword

In this post I thought it would be fun to make a list of all the named characters who died fighting for King Daemon I Blackfyre. We will obviously find out more in Fire & Blood II.

If interested: Daemon Blackfyre: The King Who Bore the Sword

Aemon Blackfyre & Aegon Blackfyre

The twin oldest sons of Daemon perished on the Redgrass Field alongside Daemon:

It's said that whenever Blackfyre and Lady Forlorn clashed, you could hear the sound for a league around. It was half a song and half a scream, they say. But when at last the Lady faltered, Blackfyre clove through Ser Gwayne's helm and left him blind and bleeding. Daemon dismounted to see that his fallen foe was not trampled, and commanded Redtusk to carry him back to the maesters in the rear. And there was his mortal error, for the Raven's Teeth had gained the top of Weeping Ridge, and Bloodraven saw his half brother's royal standard three hundred yards away, and Daemon and his sons beneath it. He slew Aegon first, the elder of the twins, for he knew that Daemon would never leave the boy whilst warmth lingered in his body, though white shafts fell like rain. Nor did he, though seven arrows pierced him, driven as much by sorcery as by Bloodraven's bow. Young Aemon took up Blackfyre when the blade slipped from his dying father's fingers, so Bloodraven slew him, too, the younger of the twins. Thus perished the black dragon and his sons.

Ser Edwyn, Ser Harold and Addam Osgrey

Ser Eustace's 3 sons (2 knights and Addam was a squire) all perished on the Redgrass Field:

He just come back from visiting the boys, down in the blackberries."

The boys were Eustace Osgrey's sons: Edwyn, Harrold, Addam. Edwyn and Harrold had been knights, Addam a young squire. They had died on the Redgrass Field fifteen years ago, at the end of the Blackfyre Rebellion. "They died good deaths, fighting bravely for the king," Ser Eustace told Dunk, "and I brought them home and buried them among the blackberries." His wife was buried there as well.

Whenever the old man breached a new cask of wine, he went down the hill to pour each of his boys a libation. "To the king!" he would call out loudly, just before he drank.

and:

Your Egg reminds me of my Addam. A brave boy, for one so young. Addam was trying to protect his wounded brother Harrold when the battle washed over them. A riverman with six acorns on his shield took his arm off with an ax."

Son of Ambrose Butterwell

Cheating here since he technically isn't named, but the Butterwells kept one foot in each camp:

"Is he a friend of your father?"

Egg made a face. "My father never liked him. In the Rebellion, Lord Butterwell's second son fought for the pretender and his eldest for the king. That way he was certain to be on the winning side. Lord Butterwell didn't fight for anyone." -The Mystery Knight

Ser Quentyn Ball aka Fireball

Also cheating here since he didn't actually die fighting, but Fireball was killed on the eve of battle:

"Did Ser Quentyn die upon the Redgrass Field?"

"Before, ser," Egg replied. "An archer put an arrow through his throat as he dismounted by a stream to have a drink. Just some common man, no one knows who."

"Those common men can be dangerous when they get it in their heads to start slaying lords and heroes."
