The secret sources of the Third Silesian War, since called "Seven-Years War," go back to 1745; nay, we may say, to the First Invasion of Silesia in 1740. For it was in Maria Theresa's incurable sorrow at loss of Silesia, and her inextinguishable hope to reconquer it, that this and all Friedrich's other Wars had their origin. Twice she had signed Peace with Friedrich, and solemnly ceded Silesia to him: but that too, with the Imperial Lady, was by no means a finis to the business. Not that she meant to break her Treaties; far from her such a thought,--in the conscious form. Though, alas, in the unconscious, again, it was always rather near! practically, she reckoned to herself, these Treaties would come to be broken, as Treaties do not endure forever; and then, at the good moment, she did purpose to be ready. "Silesia back to us; Pragmatic Sanction complete in every point! Was not that our dear Father's will, monition of all our Fathers and their Patriotisms and Traditionary Heroisms; and in fact, the behest of gods and men?" Ten years ago, this notion had been cut down to apparent death, in a disastrous manner, for the second time. But it did not die in the least: it never thinks of dying; starts always anew, passionate to produce itself again as action valid at last; and lives in the Imperial Heart with a tenacity that is strange to observe. Still stranger, in the envious Valet-Heart,--in that of Bruhl, who had far less cause! The Peace of Dresden, Christmas, 1745, seemed to be an act of considerable magnanimity on Friedrich's part. It was, at the first blush of it, "incredible" to Harrach, the Austrian Plenipotentiary; whose embarrassed, astonished bow we remember on that occasion, with English Villiers shedding pious tears. But what is very remarkable withal is a thing since discovered: [INFRA, next Note (p. 276).] That Harrach, magnanimous signature hardly yet dry, did then straightway, by order of his Court, very privately inquire of Bruhl, "There is Peace, you see; what they call Peace:--but our TREATY OF WARSAW, for Partition of this magnanimous man, stands all the same; does n't it?" To which, according to the Documents, Bruhl, hardly escaped from the pangs of death, and still in a very pale-yellow condition, had answered in effect, "Hah, say you so? One's hatred is eternal;--but that man's iron heel! Wait a little; get Russia to join in the scheme!"--and hung back; the willing mind, but the too terrified! And in this way, like a famishing dog in sight of a too dangerous leg of mutton, Bruhl has ever since rather held back; would not re-engage at all, for almost two years, even on the Czarina's engaging; and then only in a cautious, conditional and hypothetic manner,--though with famine increasing day by day in sight of the desired viands. His hatred is fell; but he would fain escape with back unbroken. HOW FRIEDRICH DISCOVERED THE MYSTERY. CONCERNING MENZEL AND WEINGARTEN.
