On that account it may often become a great aim of the operations of which we shall speak elsewhere.
Here we have still to examine some of its fundamental relations.
The moral effect of a victory increases, not merely in proportion to the extent of the forces engaged, but in a progressive ratio--that is to say, not only in extent, but also in its intensity.

In a beaten detachment order is easily restored.

As a single frozen limb is easily revived by the rest of the body, so the courage of a defeated detachment is easily raised again by the courage of the rest of the Army as soon as it rejoins it.

If, therefore, the effects of a small victory are not completely done away with, still they are partly lost to the enemy.

This is not the case if the Army itself sustains a great defeat; then one with the other fall together.
