If you can't be a pencil to write anyone's happiness, then try to be a nice eraser to remove their sadness.
I had won notable victories on paper and the map with the aid of greaseproof pencils and a typewriter. In the course of this very campaign, if one may dignify the disaster thus, I had seen French generals create imaginary "masses of manoeuvre" with strokes of the crayon and dispose of hostile concentrations, that unahappily were on the ground as well as on the map, with sweeps of the eraser. Who was I to criticise them, hero as I was of a hundred "Chinagraph wars" of make-believe?frederick e. morgan
