We find, therefore, in the whole of his conduct of War, a controlled power, always well balanced, and never wanting in energy, which in the most critical moments rises to astonishing deeds, and the next moment oscillates quietly on again in subordination to the play of the most subtle political influences.

Neither vanity, thirst for glory, nor vengeance could make him deviate from his course, and this course alone it is which brought him to a fortunate termination of the contest.
These few words do but scant justice to this phase of the genius of the great General; the eyes must be fixed carefully on the extraordinary issue of the struggle, and the causes which brought about that issue must be traced out, in order thoroughly to understand that nothing but the King's penetrating eye brought him safely out of all his dangers.
This is one feature in this great Commander which we admire in the campaign of 1760--and in all others, but in this especially--because in none did he keep the balance even against such a superior hostile force, with such a small sacrifice.
Another feature relates to the difficulty of execution.

Marches to turn a flank, right or left, are easily combined; the idea of keeping a small force always well concentrated to be able to meet the enemy on equal terms at any point, to multiply a force by rapid movement, is as easily conceived as expressed; the mere contrivance in these points, therefore, cannot excite our admiration, and with respect to such simple things, there is nothing further than to admit that they are simple.
But let a General try to do these things like Frederick the Great.

Long afterwards authors, who were eyewitnesses, have spoken of the danger, indeed of the imprudence, of the King's camps, and doubtless, at the time he pitched them, the danger appeared three times as great as afterwards.
It was the same with his marches, under the eyes, nay, often under the cannon of the enemy's Army; these camps were taken up, these marches made, not from want of prudence, but because in Daun's system, in his mode of drawing up his Army, in the responsibility which pressed upon him, and in his character, Frederick found that security which justified his camps and marches.

But it required the King's boldness, determination, and strength of will to see things in this light, and not to be led astray and intimidated by the danger of which thirty years after people still wrote and spoke.
