you are aware of the nature of RH vs LH thread? French is typically RH, but some
adopt swiss also 35mm but LH thread
Kludging a fixed cup remover, a collection of industrial hardware,
was shown on Sheldon's tips,
there are other specialized tools that hold a fixed cup wrench on the fixed cup,
to get adequate leverage without slipping..
but, lacking adequate tools, jobbing it out to the bike shop for a few bucks is a bargain.

Are you referring to the non-drive-side adjustable cup? And probably a Stronglight bottom bracket with the hexagonal wrench flats on the adjustable cup?
As always, VAR made a tool for that, although only a well-stocked old-school shop is likely to have it:

Do you have a picture of this cup? If it's got hex-shaped head for wrench, use the big spanner posted. Or a large socket with 1000-lb*ft impact wrench.

Fixed Cup Removal
It should not be removed for routine maintenance.
If you want to replace it with a sealed BB or
if there is actually something wrong with it,
then get back to me.
In simpler terms, don't f*ck with it.

This side is called the "fixed cup" for a reason.

then get back to me.

Indeed. This caused me a great deal of embarrassment on the
parade ground as well. Things are so much easier in drive side -
non drive side discussions.
To the OP, if we are indeed talking about the non drive side cup,
there are a number of tools that will allow better purchase than
an adjustable. If you have little holes in the cup, a pin spanner.
If two flats, one of these in the correct size:
https://www.amazon.com/Park-Tool-HCW-...125833&sr=1-21
But that is unlikely. In my experience (total of about 4 peugeots
owned) the adjustable cup was either pin spanner or the
aforementioned hex shape.
Many people will also advise a shot of penetrating oil
(PB Blaster - as seen on TV) allowed to soak and then
another right before your next assault.

Use a longer lever.
