 Emperor Manuel unexpectedly invaded Cilicia , forcing Thoros II to seek refuge in the mountains in December 1158 . Raynald hurried to Mamistra to voluntarily make his submission to the emperor . On Manuel 's demand , he and his retainers walked barefoot and bareheaded through the streets of the town to the imperial tent where he prostrated himself , begging for mercy . William of Tyre stated that " the glory of the Latin world was put to shame " on this occasion , because envoys from the nearby Muslim and Christian rulers were also present at Raynald 's humiliation . Manuel only forgave him after Raynald agreed to accept a Greek Patriarch in Antioch . Raynald also had to promise that he would allow a Byzantine garrison to stay in the citadel whenever it was required and would send a troop to fight in the Byzantine army . Before long , Baldwin III of Jerusalem persuaded Manuel to consent to the return of the Latin patriarch , Aimery , to Antioch , instead of installing a Greek patriarch . When the emperor entered Antioch with much pomp and ceremony on 12 April 1159 , Reginald held the bridle of Manuel 's horse . Manuel left the town eight days later .
