Hi,
I haven't yet figured out completely yet but this has definately nothing to do with Napoleon.
Nostradamus never used anagrams
PAU NAY Loron are 3 towns in the south of France at the river Gave De Pau.
This river goes from Pau to Lourdes as far as I can see.
It looks to me that there will be heavy forrest fires or something like that, and the only way to escape is swim via the river.
Century 8 Quatrain 1
PAU , NAY , LORON plus feu qu'à ƒang ƒera ,
Laude nager , fuir grand aux ƒurrez ,
Les agaƒƒas entrée refuƒera ,
Pampon , Durance les tiendra enƒerrez .
Pau, Nay, Loron, more fire than blood will be
Deviation to swim, to escape………….
The…….entered will refuse
Pampon, Durance …………………….
