_The Director_: “The commander of a patrol will see the commander of the
outguard at the place where he crosses the line of observation and give
him information as to where he is going and what he is going for. In
addition to this he secures any information that the outguard commander
may have of the country to the front and the enemy.
“This procedure is especially necessary in the present case. Sergeant
B’s mission will probably keep him out late, so that it will be after
dark when he comes back through the lines. In order to avoid chances of
being mistaken for the enemy a recognition signal should be arranged for
at this time.”
