"All I know is that we are playing against the greatest Welsh side ever", he said.
"We're going to have to be at our absolute best", Jones said.
Just as Ireland struggled against England with a makeshift full-back in Robbie Henshaw, France also - and perhaps strangely following last week's display - deployed an unfamiliar full-back in Yoann Huget to replace the injured Maxime Medard rather than use Thomas Ramos, who regularly plays in the position for Toulouse.
Jonny May claimed a hat-trick inside the first 30 minutes, while Henry Slade, Owen Farrell and a penalty try completed the demolition job.
England Women made it two bonus-point wins from two in the 2019 tournament as they beat France 41-26 at Castle Park in Doncaster. He would have been listed as a try scorer had he not been unceremoniously brought to ground without the ball by Gael Fickou with Ashton favourite to win the chase and touch down in the second-half - a penalty try being awarded and the Frenchman sin-binned.
England led 30-8 at the interval, with four tries earning a bonus-point victory, but Jones insisted the second-half performance was even better.
"Our focus and discipline to keep France scoreless was outstanding".
"At the moment we are having a great deal of success with our kicking and if you chase well it's hard to counter".
Hartley will be back in the squad as soon as he's full recovered from his injury, which I've heard might take a bit longer than it was initially expected to, and I'm not denigrating his leadership skills at all but he's the third choice hooker for me at the moment. He was making 36.8 metres for his team on every kick and he did it time and time again, his 16 kicks from hand comfortably the most from either team. More remarkably, it was the fifth consecutive match England have scored in the first two minutes.
This time a kick through from scrum-half Ben Youngs found Ashton in a huge amount of space an although the former Toulon star was hauled down short of the line, the ball came back to Slade, who cut inside for a converted try.
Jacques Brunel, the France coach, made six changes to his starting XV following that match but this humiliation meant his side had now lost 10 of their last 13 Tests.
