- rupt declivities intervene between the forces. The only
remedy in such cases is to employ the snowshoe, upon which one can move rapidly without regard to roads, and up or down hill without difficulty. Patrols can be despatched to adequate distances from the marching body on skis alone. Ski-runners can perform the same duty which cavalry performs on the plain; for instance, they can occupy points in advance which are of importance to us, dispute crossings with the enemy, and hold him at bay. Ski detachments alone are able to reconnoiter the condition of roads and test the carrying power of snow in advance of a command, and they alone can furnish the connecting links in an extended outpost position, because they alone are able to move off the roads. During halts they furnish guards; in action they easily turn the enemy's flanks, reconnoiter his weak points as well as the position of his reserves; and after the fight they maintain contact with him as patrols. They can hasten forward in advance of a command and prepare cantonments and bivouacs, and attend to the cooking.
The great depth of a detachment of ski-runners is a disadvantage. Each ski-runner takes up 2.20 m., and in addition a distance of 1 m. must be left between men. Besides, as the men are not all equally skilled in using skis, the road space taken up by a detachment of runners is increased considerably. This necessitates the employment of small detachments not exceeding 100 men. The proper sphere of ski-runners is patrol duty. In winter campaigns ski-runners are a necessary substitute for cavalry. In Scandinavia reconnaissance detachments are composed of ski-runners and cavalry, the horses pulling the runners. This permits a very rapid movement over snow-covered ground and may also be employed where the use of the much slower sled is impracticable owing to the nature of the terrain. Much practice is undoubtedly necessary to acquire proficiency
