The Battle of Lingones was fought in 298 between the Western Roman Empire and the Alamanni.

From what little is known, it seems that Constantius Chlorus, Caesar of Gaul, was travelling in the open champagne country near Lingones, (modern-day Langres in the Haute-Marne department of France), with a small escort, when he was attacked by a barbarian army which had unexpectedly crossed the Rhine.

The heavily outnumbered Caesar was worsted in a sharp skirmish from which he barely escaped, apparently receiving a wound.

So hard on his heels was the barbarian pursuit, that the wounded Caesar was reportedly hauled up the walls by rope, the garrison refusing to open the gates in the presence of so dangerous an enemy.

However, the garrisons of the surrounding cities quickly united to relieve the distressed city and emperor; the besieging camp was surprised and overrun, with sources claiming that as many as 60,000 Alemans fell in the massacre.
