n any event, the men should be taught to
take some form of a closed back to back formation. (600)

=611. Dividing column on march into two or more separate detachments.=
The column may often be broken into two or more approximately equal
detachments separated on the march by distances of 50 to 100 yards. As
a rule the detachments should not consist of less than 25 men each.
With this arrangement of the column, it will rarely be possible for an
enemy to close simultaneously with all of the detachments, one or more
being left unengaged and under control to support those engaged or to
inflict severe punishment upon the enemy when he is repulsed. (601)

=612. Selection of site for camp or bivouac; protection.= The site for
camp or bivouac should be selected with special reference to
economical and effective protection against surprise. Double sentinels
are posted on the avenues of approach, and the troops sleep in
readiness for instant action. When practicable, troops should be
instructed in advance as to what they are to do in case of attack at
night. (602)

=613. Night operations frequently advisable.= Night operations are
frequently advisable. With the small forces employed, control is not
difficult. Irregular troops rarely provide proper camp protection, and
they may frequently be surprised and severely punished by a properly
conducted night march and attack. (603)
