Daemon II had set sail a few days after he learnt that Renly Baratheon had Died and Stannis suffered a Crippling defeat against the Lannister Backed Housee Baratheon of Kingslanding, Daemon II sent the word for House Tyrell to Support Joffery until he said otherwise. He wanted an Enemy who didn't realise they had allowed an Army whose True Loyalty was to their greatest Enemy inside their Capital. But Daemon II waanted a demoralised Enemy more than anything else, and the best way to do that was to Take Casterly Rock in a Daring Night Raid.

As a child Daemon II was a heir to spare basically, and in addition to his Martial Training he had studied at the Citadel in Oldtown. He had learnt a great deal about Westeros and beyond. He had also Ttaken precautions by studying the Layout of Every major Castle in Westeros, starting with Casterly Rock. It would prove beneficial for the eventual Assault on the Lannister Fotress Later. But they were Nearing Dragonstone and this was not the time for Old memories.

So it was best if he lead his Forces in, however he would leave the Dothraki and Unsullied behind as he needed his.

As he came into the Rear side of the Targaryen Citadel with his Stone Eagles Mercenaries and as they entered through the Ancient Passage ways in absolute Silence but as they came into the Dungeons they knew at once there was someone in there.

Daemon II was locked in a Dance of Steel with Stannis, even with his Family in their Possession he refused to back down, but Daemon II wasn't willing to threaten a Young Woman like Shireen, he was only recently cured of Greyscale. And so he made a deal with Stannis, a Duel of Honor between them, winner lives and takes command of the losers forces and Equipment. Stannis and he were Once friends and Daemon II was his former squire, so he knew how Stannis thought and fought. He knew that Stannis was also a fellow follower of R'hillor, but unlike Stannis, Daemon II was a fully Inducted and Trained Red Priest, and he was higher in the Priesthood than Melisandre. So with A simple feint he cut Off Stannis Head as he went to skewer him. ''May your find peace in death Old Friend. Take the Women and Put them in the Kings Chambers, I have Plans for them.'' Says Daemon II as he tries to decide who he will fuck first.
