A single point to consider, friends. What if the Franks under Clovis I lost the Battle of Soissons to Syagrius and his Gallo-Romans in 486 A.D., the reverse of historical reality? What if they did not simply lose the battle, but lost it so thoroughly that Clovis and most of his senior commanders were killed in the fray? How long would the Roman rump state of Soissons persist following this victory?
