Historical Event in AD383

In AD383, according to Bishop Eucherius of Lyon, flooding caused part of the bank of the River Rhone to collapse, revealing a massed grave of thousands of bodies.

Eucherius identified these as a legion recruited for the Roman army from the Christians of the Theban district in Egypt, whom he claimed had been massacred nearly a century previously (near the modern village of St Maurice-en-Valais in southwestern Switzerland) for refusing to obey orders they considered immoral.

This incident, asserted by Eucherius as a matter of fact, is unrecorded elsewhere. Even the existence of this Theban legion is unclear.
