The moral effects which attend a surprise often convert the worst case into a good one for the side they favour, and do not allow the other to make any regular determination.

We have here in view more than anywhere else not only the chief Commander, but each single one, because a surprise has the effect in particular of greatly loosening unity, so that the individuality of each separate leader easily comes to light.
Much depends here on the general relation in which the two parties stand to each other.

If the one side through a general moral superiority can intimidate and outdo the other, then he can make use of the surprise with more success, and even reap good fruit where properly he should come to ruin..
