we have to reckon with the measures taken by the enemy to screen his force.[1]
Weak infantry patrols can neither break down this resistance nor create the necessary opening through which the leaders can reconnoiter in person. Stronger forces are requisite, and "reconnaissance companies" may have to be sent out toward the enemy to serve as a support for the patrols, to reinforce them when necessary, and to constitute natural collecting stations for messages. "Reconnaissances in force" are the result of these endeavors to obtain information,[2] for the defender will not reveal his dispositions unless the attacker threatens an attack. Reconnaissances in force are especially appropriate in this case, since the information obtained in regard to the position and strength of the enemy can be utilized at once. (Par. 134 German F. S. R.).
In France great importance is attached to forcibly gaining information by means of detachments of all arms which also prevent hostile reconnaissance. In minor operations the French send out infantry detachments, which, from secure hiding places, pick off observers, screen the position of their own force, and prevent the enemy from using covered avenues of approach. However, these very patrol combats may cause the commander to come to a false conclusion in regard to the hostile position. If the cavalry reconnaissance has determined that the enemy intends to accept battle within a particular area, the details of his intentions must be obtained by local reconnaissance. Then the commander will wish to know whether or not an immediate attack is feasible, or whether it is advisable to wait until nightfall for bringing up the infantry. The local reconnaissance determines where the flanks of the enemy are located; whether the position in front is the hostile main position or only an advanced post; whether the enemy
