(_b_) A point a march away in the direction of the enemy.
(_c_) The locality where the enemy is reported to be. This should be
beyond the border in enemy territory.
(_d_) Indicate whether the battalion is a right or left flank guard. For

(_j_)—(_k_)—(_l_) A road is designated in field orders by naming two or
more places located on it. Example: “The FOUR POINT—EMMITSBURG—FAIRPLAY
road.” In this case indicate in definite terms the road that the main
body of the brigade is to march on.
(_m_) Designate the hour of marching of the advance guard.
