|Fortifications are as important for the
Prince who, confident of his strength, sets out on at aggressive operation, as to the
cautious who are satisfied with self-defence.
A good fortress should have a moat with
water during all seasons, and in esplanade, with hills and dense forests around.
The fortress wall, it has been laid down,
should be high, broad, strong, and built so as to be difficult of attack by enemies'
There is a long list of defence machines to
be found in Silappadikaaram, Adaikkalakkadai chapter.
The length to be defended must not be too
great, but there must be ample space inside, and the fort must in all respects be such as
to dishearten the enemy.
