The Battle of Olivento was fought on 17 March 1041 between the Byzantine Empire and the Normans of southern Italy and their Lombard allies near the Olivento river, between the actual Basilicata and Apulia, southern Italy.
The Battle of Montemaggiore was fought on 4 May 1041, on the river Ofanto near Cannae in Byzantine Italy, between Lombard-Norman rebel forces and the Byzantine Empire. The Norman William Iron Arm led the offence, which was part of a greater revolt, against Michael Dokeianos, the Byzantine Catepan of Italy. Suffering heavy losses in the battle, the Byzantines were eventually defeated, and the remaining forces retreated to Bari. Dokeianos was replaced and transferred to Sicily as a result of the battle. The victory provided the Normans with increasing amounts of resources, as well as a renewed surge of knights joining the rebellion.
The Battle of Montepeloso was fought on 3 September 1041 between Lombard-Norman rebel forces and the Byzantine Empire, near Montepeloso in southern Italy. The Byzantines, led by Exaugustus Boioannes, were forced into battle by the rebels, and after a day-long fight the rebels defeated the Byzantine army and captured Boioannes. 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.
