Unable to flee back to his stronghold in Sicily due an Ottonian naval blockade, al-Qasim faced Otto's army in a pitched battle south of Crotone at Cape Colonna on July 14, 982. After a violent clash, a corps of Otto II's heavy cavalry destroyed the Muslim center and pushed towards al-Qasim's guards, with the Emir killed during the charge. Despite the Emir's death, the Muslim troops did not flee the battlefield but regrouped and managed to surround the Imperial soldiers, slaughtering many of them and inflicting a severe defeat upon the Emperor. According to the Muslim historian Ibn al-Athir, Imperial casualties numbered around 4,000. Landulf IV of Benevento and Pandulf II of Salerno, Bishop Henry I of Augsburg, Margrave Gunther of Merseburg, the Abbot of Fulda, and numerous other Imperial officials were among the battle's casualties.
