Relieving The Outpost
Evening and shortly before dawn are hours of special danger. The enemy
may attack late in the day in order to establish himself on captured
ground by intrenching during the night; or he may send forward troops
under cover of darkness in order to make a strong attack at early dawn.
Special precaution is therefore taken at those hours by holding the
outpost in readiness, and by sending patrols in advance of the line of
observation. If a new outpost is to be established in the morning, it
should arrive at the outpost position at daybreak, thus doubling the
outpost strength at that hour.
