Airplanes are interesting toys, but of no military value. - Ferdinand Foch

Airplanes are interesting toys but of no military value.

If France has a firm hold of the Rhine, she may be at rest, for she can be sure of reparations and security; without the Rhine she has neither. All that may be offered or given in exchange is valueless, illusory, empty. That is the position I took up immediately. We must have the Rhine line; we want nothing more and will take nothing less.

Against what should fire be opened? Against the obstacles which may delay the march of infantry. The first obstacle is the enemy gun. It will be the first objective assigned to artillery masses.
