The duties of outpost cavalry are limited to watching a strip of country to the front, and possibly on the flank, of the line of infantry outposts, and to carry messages between the different sections of the latter. Standing patrols are the most useful for observation work. In the case of an enemy close at hand, they should be in touch with him, and should, if there be no close reconnaissance patrols, watch his flanks as well; however, with proper dispositions this should be unnecessary. The standing patrols would, in any case, have to be in a position to detect and report any advance on the part of the enemy's outposts and any movement of the enemy denoting an advance or retirement. If the enemy, however, is so far away as to be out of touch with the cavalry cordon, reconnaissance work beyond this line should be carried out by those portions of the divisional cavalry that are _not_ assigned to outpost duty. If, on the other hand, the outposts on either side are in close touch, reconnaissance to the front should be carried out by infantry patrols. It may, however, be advisable under certain conditions to let weak mounted patrols follow such infantry patrols to covered positions for carrying messages, or to employ them dismounted in the place of the infantry. If these arrangements are not strictly adhered to, it very easily happens, during manoeuvres, that reconnaissance work is carried out by the reconnaissance patrols in the daytime, but at night by the outpost cavalry. In the morning the latter is then scattered in all directions and cannot be collected again. Such dispositions are also entirely opposed to the teachings of the "Field Service Manual," and are unsuited to conditions of real warfare. In time of war the reconnaissance patrols naturally continue their work of observation during the night, and consequently they need not be relieved by patrols of the outpost cavalry. In peace time, on the other hand, it is still considered remarkable if the patrols remain in touch with the enemy at night, and those that do so have been dubbed "sticky patrols." Those, also, which should really be in touch with the enemy throughout the night usually get under cover, and have been known to spend a comfortable night in excellent quarters.
