“Success,” says the Archduke Charles, “is only to be obtained by
simultaneous efforts, directed upon a given point, sustained with
constancy, and executed with decision.” It rarely happens that any
number of men who desire the same object are perfectly agreed as to the
means of attaining it; and if the will of one individual is not allowed
to predominate, there can be no _ensemble_ in the execution of their
operations; neither will they attain the end proposed. It is useless to
confirm this maxim by examples. History abounds in them.
Prince Eugene and Marlborough would never have been so successful in
the campaigns which they directed in concert, if a spirit of intrigue
and difference of opinion had not constantly disorganized the armies
opposed to them.
