we have described。
Both French and German reports are full of
incidents showing the value of observations； and
also concerning the effects of bombs。 Extracts
from the diaries of prisoners gave many interesting
features of the results of aeroplane work。
CASUALTIES DUE TO AEROPLANES。In the diary
of one was found the remark： 〃I was lucky to
escape the bomb thrown by a French aviator at
Conrobet； which killed eight of my companions。〃
Another says： 〃The Seventh Company of the
Third Regiment of the Guard had eight killed and
twenty…two wounded by bomb from a French aeroplane。〃
Another： 〃An officer showed us a torn coat
taken from one of sixty soldiers wounded by a
bomb from an aeroplane。〃
A prisoner says： 〃Near Neuville an aeroplane
bomb dropped on a supply train； killed four men；
wounded six； and killed a considerable number of
horses。〃
The Belgians； after their defeat and the capture
of Antwerp； were forced to the west along
the coast。 In some way they learned that the
Kaiser was about to occupy a chateau near Dixmunde。
Several aviators flew above the position
and dropped a number of bombs on the building；
completely wrecking it； and it was fortunate that
the Emperor left the building only twenty minutes
before； as several of his aides and soldiers
on duty were killed。
On numerous occasions the headquarters of the
different commanders have been discovered and
had to be moved to safer places。
During all these wonderful exploits which will
live in history because men had the opportunity
during the war to use them for the first time in
actual conflict； the official reports have not
mentioned the aviators by name。 The deaths of the
brave men have brought forth the acknowledgments
of their services。 During the first three
months of the war it is estimated that over sixty
aviators and aides had lost their lives in the conflict
on the two great battle lines。 This does not
take into account those who met death on the
Zeppelins； of which five had been destroyed during
that time。
