486 AD: Frankish forces under Clovis I lose the Battle of Soissons to Gallo-Romans under Syagrius when Syagrius purposely arrives to the battle site he was challenged to fight at by Clovis several days late, knowing that the Frankish King would have enjoyed all the advantages had he not done so. The Franks are caught fairly defenseless, enjoying a time of "merriment" following the victory they perceive as having come when Syagrius failed to show up at the proper day. Many of the soldiers are slaughtered, and several of the minor kings fall in the retreat, such as Ragnachar, one of the strongest of the lords. Around a third of the Army under Clovis, however, manages to flee eastwards.
Thus, the independence of the last part of Roman Authority in the West outside of Italy is preserved.
