Papus arrived shortly after the battle and this persuaded the Gauls to withdraw along the coast.
His scouts met the Celts' advance guard head-on near Telamon (modern Talamone), in an area called Campo Regio, to the surprise of both.
The fighting was fierce, with Regulus being killed early in the battle and his head brought to the Celtic leaders.
