On Pitt, amid confused clouds, there is bright dawn rising; and Friedrich too, for the last month, in Breslau, has a cheerful prospect on that Western side of his horizon. Here is one of his Postscripts, thrown off in Autograph, which Duke Ferdinand will read with pleasure: "I congratulate you, MON CHER, with my whole heart! May you FLEUR-DE-LYS every French skin of them; cutting out on their"--what shall we say (LEUR IMPRIMANT SUR LE CUE)!--"the Initials of the Peace of Westphalia, and packing them across the Rhine," tattooed in that latest extremity of fashion! [Friedrich to Duke Ferdinand, "Grussau, 19th March, 1758:" in Knesebeck, _ Herzog Ferdinand,_ i. 64. _Herzog Ferdinand wahrend des 7-jahrigen Krieges_ ("from the English and Prussian Archives") is the full Title of Knesebeck's Book: LETTERS altogether; not very intelligently edited, but well worth reading by every student, military and civil: 2 vols. 8vo. Hannover, 1857.] Friedrich, grounding partly on those Rhine aspects, has his own scheme laid for Campaign 1758. It is the old scheme tried twice already: to go home upon your Enemy swiftly, with your utmost collective strength, and try to strike into the heart of him before he is aware. Friedrich has twice tried this; the second time with success, respectable though far short of complete. Weakened as now, but with Ferdinand likely to find the French in employment, he means to try it again; and is busy preparing at Neisse and elsewhere, though keeping it a dead secret for the time. There is, in fact, no other hopeful plan for him, if this prove feasible at all. Double your velocity, you double your momentum. One's weight is given,--weight growing less and less;--but not, or not in the same way and degree, one's velocity, one's rightness of aim. Weight given: it is only by doubling or trebling his velocity that a man can make his momentum double or treble, as needed! Friedrich means to try it, readers will see how,--were the Fort of Schweidnitz once had; for which object Friedrich watches the weather like a very D'Argens, eager that the frost would go. Recapture of Schweidnitz, the last speck of Austrianism wiped away there; that is evidently the preface to whatsoever day's-work may be ahead. March 15th, frost being now off, Friedrich quits Breslau and D'Argens,--his Head-quarter thenceforth Kloster-Grussau, near Landshut, troops all getting cantoned thereabout, to keep Bohemia quiet,--and goes at once upon Schweidnitz. With the top of the morning, so to speak; means to have Schweidnitz before campaigning usually can begin, or common laborers take their tools in this trade. The Austrian Commandant has been greatly strengthening the works; he had, at first, some 8,000 of garrison; but the three months' blockade has been tight upon him and them; and it is hoped the thing can be done.
