Battle of Yunkai

In the books
In the A Song of Ice and Fire books, the Battle of Yunkai takes place in a quite different manner. Yunkai has hired both the Second Sons - led by Mero - and the Stormcrows - led by Prendahl na Ghezn, Sallor the Bald, and Daario Naharis. Daario turns over the Stormcrows to Daenerys after murdering both Prendahl and Sallor. With the Stormcrows on her side, Daenerys orders an attack against the unsuspecting Second Sons, who are getting drunk on a wagon of wine given to them by Daenerys. While her Unsullied and Dothraki attack the Yunkish slave defenders from the front, Daario's Stormcrows take them in the rear. Almost 200 Yunkish infantry is killed while the rest surrender, likewise, the Second Sons suffer minimal casualties but yield nonetheless. Mero, however, escapes.
