[Footnote 1: This was written five years ago, at a time when, though
considerable progress had been made with airship work, the aeroplane
was still in the pioneer stage of development, though Blériot had just
made his record flight across the Channel. Since then flying corps
provided with aeroplanes of improved construction have been introduced
into every great army, and the flying men have proved in actual warfare
(Tripoli, Morocco, the Balkans, France) the utility of the new means
of reconnaissance. But though aerial reconnaissance can do much more
than General von Bernhardi anticipated, it is still true that the
aviators cannot entirely supersede the cavalry. The two arms have to
work together. There are cases where the aviator can accomplish very
little. Thus, for instance, we are told that during the French advance
into the Vosges and Alsace in the present war, the wooded character
of the country led to aerial reconnaissance giving very disappointing
results.--Editor.]

studied and our cavalry have learned the lessons they suggest.--Editor.]
