Helvetii pl
(historical) A Gallic tribe that occupied the plain of Switzerland.
Another part of the nation moved west with the Helvetii into southern France, which was one of the events leading to the interventions of Julius Caesar's Gaulish campaign of 58 BC. Source: Internet
Caesar did not pursue them until three days after the battle, while still sending messengers to the Lingones warning them not to assist the Helvetii in any way. Source: Internet
For a start, only one out of the fifteen Celtic oppida in the Helvetii territory so far has yielded evidence for destruction by fire. Source: Internet
However, it is clear that Caesar’s warning to the Lingones not to supply his enemies was quite enough to make the Helvetii leaders once again offer peace. Source: Internet
Later on, they attacked the city of Noreia (in modern Austria) shortly before a group of Boii (32,000 according to Julius Caesar - the number is probably an exaggeration) joined the Helvetii in their attempt to settle in western Gaul. Source: Internet
Leaving the largest part of their supplies behind, the Helvetii covered around 60 km in four days, eventually reaching the lands of the Lingones (the modern Langres plateau). Source: Internet
