[6] Chnodomarius is known to have commanded the army which defeated the Roman Magister Peditum (Master of Foot) Barbatio in 357, driving him south to Augst, and disabling him from further action during the campaign.
[9] The full force of the Alemannic confederation, iterated by Ammianus as seven kings, ten petty princes, and thirty-five thousand common soldiers, assembled at Strasbourg.
[13] Apparently, their fears were justified; as soon as the tide of battle turned in Julian's favour, Chnodomarius and a small body of retainers made discreetly for a boat which was waiting on the riverbank.
[14][15] Ammianus Marcellinus, in his account of the Battle of Strasbourg, describes Chnodomarius as "brave as a warrior and general, eminent for skill above his fellows", and very large and strong, even by barbarian standards.
Chnodomarius was allegedly brought before Julian in an abject and frightened condition, throwing himself on the ground and pleading for mercy until the bemused Caesar stopped him with a reassuring speech.
