Chess Nightmare

I have recently found this very interesting problem in the first issue of « L’Echiquier Français » published in Paris in 1906.

Unfortunately, the name of the composer of this problem  is not given in the magazine, but it is indicated that it dates back to the 18th century.

That’s the position and white to move !

White mates !

Very easy indeed ! but White has to mate with the c pawn, without letting move any black pawn, and without taking one single black pawn !!!
