Almost, except that the Crusaders did not rout the army per ce. Over half the army deserted because the army was a sort of conglameration of various Seljuq petty rulers under the overall command of a guy named Kür Bagha, these subordinate commanders feared that Kür Bagha would become too powerful if he won, thus endangering the realms they had carved out for themselves. When they deserted most of the troops who did not know what was going on thought it was a rout and fled themselves. Many of the Crusaders claim to have seen armoured angels driving away the Turkish forces and thus they were filled with what you fiery fanaticism, the Turkish troops who were not fast enough to get away were mostly slaughtered.
