A few battalions dispersed about a town, inspire no terror; but shut
up in the more narrow outline of a citadel, they assume an imposing
attitude. For this reason it appears to me that such a precaution
is always necessary, not only in fortresses, but wherever there are
hospitals or depôts of any kind. Where there is no citadel, some
quarter of the town should be fixed upon most favorable for defence,
and entrenched in such a manner as to oppose the greatest resistance
possible.
