Battle of Lingones

Few of the battles of that age, in the 130-year gap between the period recorded by Dio Cassius and Ammianus Marcellinus, are in any degree adequately recorded. 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 Hautes-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. He took shelter in Langres, where the enemy surrounded the remnants of his broken force. 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, and 6,000 Alemans fell in the massacre.[1]
