6. Danger of startling a friend sentinel by unwarned approach.

Eleventh Problem--Detached Post:

A. Definition and Function.--Posted where connection cannot be
easily maintained with other elements of outpost. Sent usually by
outpost reserve or by main body, and retires to them, rather than to
the line of supports. Function same as element of outpost
proper,--_observation, resistance, reconnaissance_; but less
resistance than _warning_. May be as small as 2 men, or as large as a
support, depending on location and importance of detached position.

B. Principles.

1. Established under precautions, because of danger of enemy
breaking between the main body and the detached post.
2. Entrenchment: what time of day? What other circumstances?
Treatment of bridges? Night?
3. Requisitioning order: Need of payment; for justice, for
military advantage later (reassure farmers through whose
territory you will need to pass and keep supplied).

Twelfth Problem--Requisitioning Detachment or Patrol:

A. Definition and Function.--A patrol may have any mission: here
it is sent to take (on payment) the provender designated. A.r.d. sent
by commander with specific instructions, is legal; a raid for booty
illegal. (See f.s.r., sec, 290.)

B. Principles.
