Catus Alessiâs “Battle of Alessia” – This was thought to take place on the 3rd of October, 52 BCE. That means on the applicable version of the Coligny Calendar, it took place on 17 Ogronios. The holiday was originally developed by one Deuognatos. BNG observes by the Coligny Calendar and not the Gregorian. As such, like any other holiday, the Gregorian date will differ year to year.
The Siege of Alessia resulted in the end of a Free Gaul, and the deaths of thousands, including noncombatants. This is, as one may imagine, a holiday of mourning for the great loss that shaped history ever after.
The focus here is placed on those who died at Alessia, and/or our Gaulish ancestors in a general sense.
