Part 36 (1/2)
By day, cavalry reconnoiters in advance of the line of observation. At night, however, that the horses may have needed rest and because the work can be done better by infantry, the greater part of the cavalry is usually withdrawn in rear of the supports, generally joining the reserve, small detachments being a.s.signed to the supports for patrolling at a distance.
With efficient cavalry in front, the work of the infantry on the line of observation is reduced to a minimum.
General instructions for the advance cavalry are given by the outpost commander, but details are left to the subordinate.
Instead of using outguards along the entire front of observation, part of this front may be covered by patrols only. These should be used to cover such sections of the front as can be crossed by the enemy only with difficulty and over which he is not likely to attempt a crossing after dark.
In daylight much of the local patrolling may be dispensed with if the country can be seen from the posts of the sentinels. However, patrols should frequently be pushed well to the front unless the ground in that direction is exceptionally open.
Patrols or sentinels must be the first troops which the enemy meets, and each body in rear must have time to prepare for the blow. These bodies cause as much delay as possible without sacrificing themselves, and gradually retire to the line where the outpost is to make its resistance.
Patrols must be used to keep up connection between the parts of the outpost except when, during daylight, certain fractions or groups are mutually visible. After dark this connection must be maintained throughout the outpost except where the larger subdivisions are provided with wire communication.
In addition to ordinary outguards, the outpost commander may detail from the reserve one or more detached posts to cover roads or areas not in the general line a.s.signed to the supports.
In like manner the commander of the whole force may order detached posts to be sent from the main body to cover important roads or localities not included in the outpost line.
The number and strength of detached posts are reduced to the absolute needs of the situation.
ESTABLIs.h.i.+NG THE OUTPOST
The outpost is posted as quickly as possible, so that the troops can the sooner obtain rest. Until the leading outpost troops are able to a.s.sume their duties, temporary protection, known as the march outpost, is furnished by the nearest available troops.
The halt order of the commander, besides giving the necessary information and a.s.signing camp sites to the parts of the command, details the troops to const.i.tute the outpost, a.s.signs a commander therefor, designates the general line to be occupied, and, when practicable, points out the position to be held in case of attack.
The outpost commander, upon receipt of this order, should issue the outpost order with the least practicable delay. In large commands it may often be necessary to give the order from the map, but usually the outpost commander will have to make some preliminary reconnaissance, unless he has an accurate and detailed map.
The order gives such available information of the situation as is necessary to the complete and proper guidance of subordinates; designates the troops to const.i.tute the supports; a.s.signs their location and the sector each is to cover; provides for the necessary detached posts; indicates any special reconnaissance that is to be made; orders the location and disposition of the reserve; disposes of the train if same is ordered to join the outpost; and informs subordinates where information will be sent.
After issuing the initial orders, the outpost commander inspects the outpost, orders the necessary changes or additions, and sends his superior a report of his dispositions.
The reserve is marched to its post by its commander, who then sends out such detachments as have been ordered and places the rest in camp or bivouac, over which at least one sentinel should be posted. Connection must be maintained with the main body, the supports, and nearby detached posts.
The supports march to their posts, using the necessary covering detachments when in advance of the march outpost. A support commander's order should fully explain the situation to subordinates, or to the entire command, if it be small. It should detail the troops for the different outguards and, when necessary, define the sector each is to cover. It should provide the necessary sentinels at the post of support, the patrols to be sent therefrom, and should arrange for the necessary intrenching. Connection should be maintained with the adjoining supports and with the outguards furnished by the supports.
In posting his command the support commander must seek to cover his sector in such manner that the enemy cannot reach, in dangerous numbers and un.o.bserved, the position of the support or pa.s.s by it within the sector intrusted to the support. On the other hand, he must economize men on observation and patrol duty, for these duties are unusually fatiguing. He must practise the greatest economy of men consistent with the requirements of practical security.
As soon as the posting of the support is completed, its commander carefully inspects the dispositions and corrects defects, if any, and reports the disposition of his support, including the patrolling ordered, to the outpost commander. This report is preferably made by means of a sketch.
Each outguard is marched by its commander to its a.s.signed station, and especially in the case of a picket, is covered by the necessary patrolling to prevent surprise.
