Battle of Montepeloso

Irsina, Province of Matera, It

On 3 September 1041 at the Battle of Montepeloso, the Normans (nominally under Arduin and Atenulf) defeated Byzantine catepan Exaugustus Boioannes and brought him to Benevento. Around that time, Guaimar IV of Salerno began to attract the Normans. The decisive rebel victory forced the Byzantines to retreat to the coastal cities, leaving the Normans and Lombards in control of the whole interior of southern Italy.
