There was no denying it: the Cavour of Germany was Stein. But was the work done? Had the Congress of Vienna settled anything, for was that still left to do without which the independence and well-being of forty millions of Germans was unguaranteed, and the peace of all Europe uninsured? If so, what remained to be achieved? to complete what the German Cavour, the Precursor Stein, had begun, to embody and make real the glorious dreams of which Queen Louise had been the symbol, the Joan of Arc?[8] [8] I would recommend every student of history to read attentively the extraordinary article of M. Paleologue in the _Revue des Deux Mondes_ entitled "_La Reine Louise de Prusse Comment se Fait une Legende_." It is a poetic but true suite to Professor Levy Bruehl's magnificent study. That, indeed, brought the Hohenzollerns on the scene, and lent to prosaic history its legend, giving to Frederick's "big battalions" the white-robed heroine who should lead them on. Whether, through the long years of indecision, during which disorder and revolution seemed the danger to be averted, the future "Chancellor of Iron" matured his plans after the manner of Newton, by "forever thinking of them" is still a question to be adequately answered by himself alone. This much is certain that when, in 1863-64, the subject of the Duchies cast its shadow on the path, it revealed its importance to Bismarck, as it had done fourteen years previously to Dahlmann, and stood forth distinctly as the initial syllable of the one mystical word, _Unity_. _Schleswig-Holstein_ was, as a matter of fact, and by all its several complications, the German question; it was its sign and portent, and if action of some sort were not taken thereupon, the door set ajar was closed upon the future, for a generation at least. Palmerston's declaration, than which no unwiser one was ever made, touching the insanity of the man who should seek to understand the enigma of the Danish Duchies, was adopted in England solely from the dense and inconceivable ignorance of the British mind on all German topics, and the equally inexplicable but inborn dislike of all British politicians to grapple with any serious study of them. It was the problem to which no German of the North could show indifference; and it was the one subject which brought Prussia to the fore, and put her reigning house in the van, forcing the Hohenzollerns into predominance. This was a crucial point, and wondrous to record! the will of Bismarck on that exceedingly curious detail brought the Hapsburgs together with the Hohenzollerns; Frederick with Marie-Therese, Wallenstein's camp with Rebels, in an unescapable atmosphere of rank Germanism!
