Page "Boii" Paragraph 3

Around 60 BC, a group of Boians joined the Helvetians ' ill-fated attempt to conquer land in western Gaul and were defeated by Julius Caesar, along with their allies, in the battle of Bibracte.

Caesar settled the remnants of that group in Gorgobina, from where they sent two thousand to Vercingetorix's aid at the battle of Alesia six years later.

The eastern Boians on the Danube were incorporated into the Roman Empire in 8 AD.
