compared with the other. Owing to the insignificance of the distances in tactics, the movements of one army in a battle, take place almost in sight of the other; the army, therefore, on the exterior line, will generally very soon be made aware of what his adversary is doing. From the long distances, with which strategy has to deal, it very seldom happens, that the movement of one army, is not concealed from the other for at least a day, and there are numerous instances, in which especially if the movement is only partial, such as a considerable detachment, that it remains secret for weeks.—It is easy to see, what a great advantage this power of concealing movements must be to that party, who through the nature of his position has reason to desire it most.
We here close our considerations on the convergent and divergent use of forces, and the relation of those forms to attack and defence, proposing to return to the subject at another time.
