From George R.R. Martin’s book Fire & Blood, the history of the Targaryen dynasty that ruled Westeros for three hundred years.

I slew a thousand of them, but it will not bring him back”
Prince Baelon Targaryen’s pain for his lost brother

As soon as Baelon Targaryen returned to King’s Landing, after having killed countless Myrish enemies with Dark Sister (the Valyrian steel longsword), while his dragon Vhagar burned their fleet; mounted off his dragon Vhagar and fell into his mother Queen Alysanne’s embrace.
After the fury of killing thousand of enemies in vengeance, the pain was still unbearable!

He fought, in what was to become known as Prince Baelon’s Wroth, to avenge his brother Aemon previously killed dishonorably by Myrish invaders.

The quote comes from the Fire & Blood chapter:
The Long Reign Jaehaerys and Alysanne: Policy, Progeny, and Pain

Reference excerpt from the books: The Long Reign Jaehaerys and Alysanne: Policy, Progeny, and Pain; Fire & Blood

Baelon the Brave played his part in the slaughter, with Dark Sister in his hand.
When he returned to King’s Landing with his brother’s corpse, the smallfolk lined the streets screaming his name and hailing him as a hero.
But it is said that when he saw his mother again, he fell into her arms and wept
I slew a thousand of them,
he said
but it will not bring him back
And the queen stroked his hair and said
I know, I know.

And the queen stroked his hair and said I know, I know.
