A Storm of Swords
The Stormcrows were hired to help defend Yunkai against the threat of Daenerys Targaryen. They were placed on the right of the defensive line facing the army of Daenerys. The captains of the Stormcrows, Prendahl na Ghezn, Sallor the Bald and Daario Naharis attended the parley with Daenerys. She offered the captains gold and plunder if the Stormcrows came over to her side, but was rebuffed by Prendahl. The Stormcrows were a company of freed men and therefore the question of breaking the contract with Yunkai would have to be put to each man and while that debate was going on in the camp, Daario, won over by Daenerys, killed Prendahl and his fellow captain Sallor the Bald and brought the Stormcrows over to Daenerys.
