Châlons (Revolt of the Legions of Aquitaine).
Fought 271, between the troops of the Emperor Aurelian, and the revolted legions under Tetricus. Tetricus, who was only a puppet in the hands of his soldiers, concerted measures with Aurelian for their destruction, and so posted his forces as to give the Emperor the advantage, after which he deserted, with a few followers. The revolted legionaries fought desperately, but were cut to pieces.
