Friedrich stayed hardly one day in Neissen Country; Silesia, in the jaws of destruction, requiring such speed from him. His new Series of Marches thitherward, for the next two weeks especially, with Daun and Lacy, and at last with Loudon too, for escort, are still more singular than the foregoing; a fortnight of Soldier History such as is hardly to be paralleled elsewhere. Of his inward gloom one hears nothing. But the Problem itself approaches to the desperate; needing daily new invention, new audacity, with imminent destruction overhanging it throughout. A March distinguished in Military Annals;--but of which it is not for us to pretend treating. Military readers will find it in TEMPELHOF, and the supplementary Books from time to time cited here. And, for our own share, we can only say, that Friedrich's labors strike us as abundantly Herculean; more Alcides-like than ever,--the rather as hopes of any success have sunk lower than ever. A modern Alcides, appointed to confront Tartarus itself, and be victorious over the Three-headed Dog. Daun, Lacy, Loudon coming on you simultaneously, open-mouthed, are a considerable Tartarean Dog! Soldiers judge that the King's resources of genius were extremely conspicuous on this occasion; and to all men it is in evidence that seldom in the Arena of this Universe, looked on by the idle Populaces and by the eternal Gods and Antigods (called Devils), did a Son of Adam fence better for himself, now and throughout. This, his Third march to Silesia in 1760, is judged to be the most forlorn and ominous Friedrich ever made thither; real peril, and ruin to Silesia and him, more imminent than even in the old Leuthen days. Difficulties, complicacies very many, Friedrich can foresee: a Daun's Army and a Lacy's for escort to us; and such a Silesia when we do arrive. And there is one complicacy more which he does not yet know of; that of Loudon waiting ahead to welcome him, on crossing the Frontier, and increase his escort thenceforth!--Or rather, let us say, Friedrich, thanks to the despondent Henri and others, has escaped a great Silesian Calamity;--of which he will hear, with mixed emotions, on arriving at Bunzlau on the Silesian Frontier, six days after setting out. Since the loss of Glatz (July 26th), Friedrich has no news of Loudon; supposes him to be trying something upon Neisse, to be adjusting with his slow Russians; and, in short, to be out of the dismal account-current just at present. That is not the fact in regard to Loudon; that is far from the fact. LOUDON IS TRYING A STROKE-OF-HAND ON BRESLAU, IN THE GLATZ FASHION, IN THE INTERIM (July 30th-August 3d).
