Abu'l-Qasim was not far from
Rossano Calabro when he noticed the unexpected strength of Otto's troops and retreated. Tipped off to the retreat by ships, Otto left his wife
Theophanu and their children in Rossano, along with the baggage and the imperial treasure, and set off to pursue the enemy. When Abu'l-Qasim recognized that he would not be able to flee, he readied his army for a
pitched battle at
Capo Colonna, south of Crotone. After a violent clash, a corps of German heavy cavalry destroyed the Muslim center and then pushed towards the emir's guards. Abu'l-Qasim was ultimately killed during the battle, but his troops were not shaken, going on to surround Otto's forces with a hidden reserve of approximately 5,000 cavalry and inflicting heavy losses. According to
Ibn al-Athir's history, casualties numbered around 4,000, among them
Landulf IV of Benevento,
Henry I, Bishop of Augsburg,
Günther, Margrave of Merseburg, the
Abbot of Fulda, and 19 other German counts. Otto was forced to flee the battle, ultimately securing shelter only by swimming out to a Byzantine merchant ship. He then rested in Rossano, only returning to Rome on 12 November 982. ==Election of Otto III==
