Few Generals in this situation would have believed these simple strategic means to be practicable.
Again, another difficulty in execution lay in this, that the King's Army in this campaign was constantly in motion.

Twice it marched by wretched cross-roads, from the Elbe into Silesia, in rear of Daun and pursued by Lascy (beginning of July, beginning of August).

It required to be always ready for battle, and its marches had to be organised with a degree of skill which necessarily called forth a proportionate amount of exertion.
Although attended and delayed by thousands of waggons, still its subsistence was extremely difficult.

In Silesia, for eight days before the battle of Leignitz, it had constantly to march, defiling alternately right and left in front of the enemy:--this costs great fatigue, and entails great privations.
Is it to be supposed that all this could have been done without producing great friction in the machine?
Can the mind of a Commander elaborate such movements with the same ease as the hand of a land surveyor uses the astrolabe?
Does not the sight of the sufferings of their hungry, thirsty comrades pierce the hearts of the Commander and his Generals a thousand times?
Must not the murmurs and doubts which these cause reach his ear?
Has an ordinary man the courage to demand such sacrifices, and would not such efforts most certainly demoralise the Army, break up the bands of discipline, and, in short, undermine its military virtue, if firm reliance on the greatness and infallibility of the Commander did not compensate for all?
Here, therefore, it is that we should pay respect; it is these miracles of execution which we should admire.

But it is impossible to realise all this in its full force without a foretaste of it by experience.
