Wales under-20s were condemned to their first ever Six Nations Wooden Spoon after being thumped 67-17 by France in Oyonnax.
Leo Drouet bagged four of France's eleven tries on the night, while Louis Bielle-Biarrey and Nicolas Depoortere both earned a brace apiece in what was a truly dominant performance,
Wales briefly showed some signs of life with two converted scores of their own after the break, but were firmly second best in almost every department here.
The result condemns Wales to the bottom of the table without a single win to their name.
Meanwhile, the bonus-point win secured second place for France behind Grand Slam winners Ireland, who defeated England 36-24 earlier in the day.
Wales boss Byron Hayward made five changes from the defeat to Italy last time out, but his hopes of ending a disappointing tournament with a victory were ruthlessly dismantled at a rainy Stade Charles-Mathon.
Perhaps the only blot on an otherwise near flawless first half for the hosts was a yellow card to Thomas Lacombre inside the very first minute - the 18-year-old colliding with Wales full-back Cameron Winnett while attempting to charge down an early kick upfield.
Winnett was unable to continue, and had to be replaced by debutant Kian Abrahams, while Edwards took advantage to kick over the resulting penalty to hand Wales an early lead.
A mixed start for Wales then, but it was about as good as it would get in the first 40 minutes.
Indeed, despite their numerical disadvantage, France hit back almost straight away, rolling through the phases before Baptiste Jauneau eventually went over in the corner.
Five minutes later, the effervescent hosts had another. A superb kick chase forced Wales to surrender possession deep inside their own half, before some slick passing eventually gave Posolo Tuilagi space to crash over underneath the posts.
France continued to turn the screw, a brilliant 5m scrum again worked through the hands for their third try of the match, with Depoortere the man to go over the line.
Marko Gazzotti arguably embodied France's superiority, producing some seriously impressive carries that bulldozed holes inside the wall of red shirts on several occasions.
The 18-year-old was at the heart of his side's fourth try just before the half hour mark, opening up a gap on the outside for Drouet to take full advantage and go over.
Wales tried to muster up a response, but were punished for a fumble just shy of the French goal line. Gazzotti mopped up, before offloading to Jauneu, who hit the gas to race away up the other end of the pitch.
Llien Morgan managed to halt him just inside the 22, only for Drouet to swoop in and gobble up the offload before bursting through for his second try of the night.
There was still time for a sixth before half-time. A typically well worked line-out on the halfway line was, in the blink of an eye, worked out to Depoortere, who looked inside to set up Louis Bielle-Biarrey to go over.
Wales, to their credit, did respond just after the break, a cute bit of creativity from Morgan Morse left the French defence flat-footed, opening up a gap for Edwards to squeak through the gap and snatch a converted score.
The visitors bagged a second try just a few minutes later, edging their way through the phases close to the line before Lewis Morgan eventually wriggled his way through the bodies to touch down.
But France soon regained their composure, and Drouet secured his hat-trick just after 53 minutes after getting on the end of Leo Carbonneau's cheeky chip on the edge of the maul to touch down in the corner.
That score appeared to give France their mojo back and, after wave after wave of attacks, Emilien Gailleton eventually added another five points just after the hour.
Drouet would have had another had he managed to keep his boots in play just five minutes later, but Bielle Biarrey did keep the scoreboard ticking over after getting on the end of Gailleton's chip over the Welsh defence courtesy of some blistering pace.
Gailleton then teed up Depoortere, who sliced through a tired and increasingly desperate Wales defence to add another converted try.
France saw out the game as they began it when Mathis Castro-Ferreira was sent to the sin bin late on for a high tackle, but again it failed to really take the gloss off what was a thoroughly impressive win for Les Bleuets, with Drouet rounding off yet another sublime move to finish the night with his fourth try.
