Thus there can be no doubt that in countries of vast dimensions, and when there is no extraordinary disproportion between the belligerent powers, a relation may be produced in this way between the military forces, which holds out to the defensive an immeasurably greater chance of a final result in his favour than he would have had if there had been a great battle on the frontier. Not only does the probability of gaining a victory become greater through this alteration in the proportions of the contending armies, but the prospects of great results from the victory are increased as well, through the change of position. What a difference between a battle lost close to the frontier of our country and one in the middle of the enemy’s country! Indeed, the situation of the assailant is often such at the end of his first start, that even a battle gained may force him to retreat, because he has neither enough impulsive power left to complete and make use of a victory, nor is he in a condition to replace the forces he has lost.
There is, therefore, an immense difference between a decisive blow at the commencement and at the end of the attack.
To the great advantage of this mode of defence are opposed two drawbacks. The first is the loss which the country suffers through the presence of the enemy in his advance, the other is the moral impression.
To protect the country from loss can certainly never be looked upon as the object of the whole defence. That object is an advantageous peace. To obtain that as surely as possible is the endeavour, and for it no momentary sacrifice must he considered too great. At the same time, the above loss, although it may not be decisive, must still be laid in the balance, for it always affects our interests.
This loss does not affect our army directly; it only acts upon it in a more or less roundabout way, whilst the retreat itself directly reinforces our army. It is, therefore, difficult to draw a comparison between the
