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.
Châlons (Invasion of the Alemanni).
Fought July 366 between the Romans under Jovinus, and the Alemanni under Vadomair. After an obstinate engagement, lasting throughout the day, the Alemanni were routed with a loss of 6,000 killed and 4,000 prisoners. The Romans lost 1,200.
Châlons (Invasion of the Huns).
Fought 451 between the Romans and the Visigoths under Actius and Theodoric respectively, and the Huns under Attila. The battle was fought on an open plain, and while the right and centre of the allies withstood Attila's onslaught, the Visigoths on the left made a furious charge, in which Theodoric fell, and totally routed the right of the Huns. Attila then withdrew to his camp, having suffered heavy loss, and prepared to resist the attack of the allies on the following day. Actius, however, did not renew the conflict, and allowed Attila to retreat unmolested.
Châlons.
Arising out of a tournament in 1274, in which the life of Edward I was endangered by foul play, a fight in earnest took place between the English and French knights present. The French were worsted, and a considerable number slain. This fight is called the "Little" Battle of Châlons.
Champ-Aubert (Allied Invasion of France).
Fought February 10, 1814, when Napoleon with his main army, by an extraordinary forced march through a difficult country, fell upon Blucher's army marching upon Paris, viâ Châlons. Blucher was advancing in three divisions, and Napoleon attacked the second of these, under Alsusieff, and completely dispersed it, taking 2,000 prisoners and all the guns. On the following day he encountered Sachen, who with 20,000 men formed the advance guard, and defeated him at Montmirail, with a loss of 6,000, forcing him to abandon the main road and retire on Château Thierry. On the 13th he encountered General d'York, with 30,000 Russians and Prussians at Château Thierry, driving him out with heavy loss, including 3,000 prisoners, while finally on the 14th he turned on the main body under Blucher himself, who, not being sufficiently strong to face the main French army, was compelled to retire, which he did in good order, after losing 3,000 in killed, wounded, and prisoners. This flank march is considered one of Napoleon's most brilliant achievements.
