Once the perimeter has been penetrated, one becomes concerned with invisibility inside the
camp. There are six basic positions which may be used to conceal your presence.
A position above the enemy is the first of these. As has been mentioned, most people look at
the horizon or scan their surroundings at eye level. The Ninja uses this propensity to his advantage.
Approaching the point of penetration across the rooftops is fairly safe so long as one
keeps low to avoid silhouetting. Further, one can flatten out on the roof and observe the enemy
There is an ancient legend of a Ninja who entered an enemy camp and penetrated the attic of
the enemy general. The Ninja drilled a tiny hole in the ceiling of the general’s bedroom, lowered
a thread through the opening, and dripped poison into the general’s mouth as he slept. Attics
are also excellent places to eavesdrop. Care must be taken to support one’s weight only on
the rafters, since many ceilings cannot support a person’s weight.
