In the late sixth century Gundovald, a Frank of royal blood, returned from a lengthy exile in Italy and Constantinople to establish a regnum in the southwestern part of Gaul. His half brother, Guntram, who ruled the neighboring Burgundian region, vigorously opposed this intrusion. In this fascinating narrative, Bernard Bachrach provides a comprehensive reinterpretation of the dramatic attempt by Gundovald to succeed to the Merovingian throne with the help of the Byzantine Empire. Gundovald, a Merovingian prince, was rejected by his father, King Chlotar I, and declared not to be of royal blood. His association with the Byzantine Empire led Guntram to regard him as an "imperial puppet." . In addition to examining the highly controversial diplomatic machinations behind Gundovald's bid for power, Bachrach breaks new ground with a thorough assessment of the strategy, tactics, and military technology of the "little war" fought between Gundovald's supporters and the armies of King Guntram. This conflict ended with the siege of the old Roman fortress city of Convenae in the foothills of the Pyrenees.
