Friedrich, by degrees, has considerably changed his opinion, and bent towards the late Keith's, about Russian Soldiery: a Soldiery of most various kinds; from predatory Cossacks and Calmucks to those noble Grenadiers, whom we saw sit down on the Walls of Schweidnitz when their work was done. A perfectly steady obedience is in these men; at any and all times obedient, to the death if needful, and with a silence, with a steadfastness as of rocks and gravitation. Which is a superlative quality in soldiers. Good in Nations too, within limits; and much a distinction in the Russian Nation: rare, or almost unique, in these unruly Times. The Russians have privately had their admirations of Friedrich, all this while; and called him by I forget what unpronounceable vernacular epithet, signifying "Son of Lightning," or some such thing. [Buchholz, Neueste Preussisch-Brandenburgische Geschichte (1775), vol ii. (page irrecoverable).] No doubt they are proud to have a stroke of service under such a one, since Father Peter Feodorowitsh graciously orders it: the very Cossacks show an alertness, a vivacity; and see cheery possibilities ahead, in Countries not yet plundered out. They stayed with Friedrich only Three Weeks,—Russia being an uncertain Country. As we have seen above; though Friedrich, who is vitally concerned, has not yet seen! But their junction with him, and review by him in the Field of Lissa, had its uses by and by; and may be counted an epoch in Russian History, if nothing more. The poor Russian Nation, most pitiable of loyal Nations,—struggling patiently ahead, on those bad terms, under such CATINS and foul Nightmares,—has it, shall we say, quite gone without conquest in this mad War? Perhaps, not quite. It has at least shown Europe that it possesses fighting qualities: a changed Nation, since Karl XII. beat them easily, at Narva, 8,000 to 80,000, in the snowy morning, long since!—

Czernichef once come, and in his place in the Camp of Tintz, business instantly begins,—business, and a press of it, in right earnest;—upon the hitherto idle Daun. July 1st, there is general complex Advance everywhere on Friedrich's part; general attempt towards the Mountains. Upon which Daun, well awake, at once rolls universally thitherward again; takes post in front of the Mountains,—on the Heights of Kunzendorf, to wit (Loudon's old post in Bunzelwitz time);-and elaborately spreads himself out in defence there. "Take him multifariously by the left flank, get between him and his Magazine at Braunau!" thinks Friedrich. Discovering which, Daun straightway hitches back into the Mountains altogether, leaving Kunzendorf to Friedrich's use as main camp. His outmost Austrians, on the edge of the Mountain Country, and back as far as suitable, Daun elaborately posts; and intrenches himself behind them in all the commanding points,—Schweidnitz still well in sight; and Braunau and the roads to it well capable of being guarded. Daun's Head-quarter is Tannhausen; Burkersdorf, Ludwigsdorf, if readers can remember them, are frontward posts:—in his old imperturbable way Daun sits there waiting events.

And for near three weeks there ensues a very multiplex series of rapid movements, and alarming demonstrations, on Daun's front, on Daun's right flank; with serious extensive effort (masked in that way) to turn Daun's left flank, and push round by Landshut Country upon Bohemia and Braunau. Effort very serious indeed on that Landshut side: conducted at first by Friedrich in person, with General Wied (called also NEUwied, a man of mark since Liegnitz time) as second under him; latterly by Wied himself, as Friedrich found it growing dubious or hopeless. That was Friedrich's first notion of the Daun problem. There are rapid marches here, there, round that western or left flank of Daun; sudden spurts of fierce fighting, oftenest with a stiff climb as preliminary: but not the least real success on Daun. Daun perfectly comprehends what is on foot; refuses to take shine for substance; stands massed, or grouped, at his own skilful judgment, in the proper points for Braunau, still more for Schweidnitz; and is very vigilant and imperturbable.

Kunzendorf Heights, which are not of the Hills, but in front of them, with a strip of flat still intervening;—these, we said, Daun had at once quitted: and these are now Friedrich's;—but yield him a very complex prospect at present. A line of opposing Heights, Burkersdorf, Ludwigsdorf, Leuthmannsdorf, bristling with abundant cannon; behind is the multiplex sea of Hills, rising higher and higher, to the ridge of the Eulenberg in Glatz Country 10 or 12 miles southward: Daun, with forces much superior, calmly lord of all that; infinitely needing to be ousted, could one but say how! Friedrich begins to perceive that Braunau will not do; that he must contrive some other plan. General Wied he still leaves to prosecute the Braunau scheme: perhaps there is still some chance in it; at lowest it will keep Daun's attention thitherward. And Wied perseveres upon Braunau; and Braunau proving impossible, pushes past it deeper into Bohemia, Daun loftily regardless of him. Wied's marches and attempts were of approved quality; though unsuccessful in the way of stirring Daun. Wied's Light troops went scouring almost as far as Prag,—especially a 500 Cossacks that were with him, following their old fashion, in a new Country. To the horror of Austria; who shrieked loudly, feeling them in her own bowels; though so quiet while they were in other people's on her score. This of the 500 Cossacks under Wied, if this were anything, was all of actual work that Friedrich had from his Czernichef Allies;—nothing more of real or actual while they stayed, though something of imaginary or ostensible which had its importance, as we shall see.

Friedrich, in the third week, recalls Wied: "Braunau clearly impossible; only let us still keep up appearances!" July 18th, Wied is in Kunzendorf Country again; on an important new enterprise, or method with the Daun Problem, in which Wied is to bear a principal hand. That is to say, The discomfiture and overturn of Daun's right wing, if we can,—since his left has proved impossible. This was the STORMING OF BURKERSDORF HEIGHTS; Friedrich's new plan. Which did prove successful, and is still famous in the Annals of War: reckoned by all judges a beautiful plan, beautifully executed, and once more a wonderful achieving of what seemed the impossible, when it had become the indispensable. One of Friedrich's prettiest feats; and the last of his notable performances in this War. Readers ought not to be left without some shadowy authentic notion of it; though the real portraiture or image (which is achievable too, after long study) is for the professional soldier only,—for whom TEMPELHOF, good maps and plenty of patience are the recipe.

"The scene is the Wall of Heights, running east and west, parallel to Friedrich's Position at Kunzendorf; which form the Face, or decisive beginning, of that Mountain Glacis spreading up ten miles farther, towards Glatz Country. They, these Heights called of Burkersdorf, are in effect Daun's right wing; vitally precious to Daun, who has taken every pains about them. Burkersdorf Height (or Heights, for there are two, divided by the Brook Weistritz; but we shall neglect the eastern or lower, which is ruled by the other, and stands or falls along with it), Burkersdorf Height is the principal: a Hill of some magnitude (short way south of the Village of Burkersdorf, which also is Daun's); Hill falling rather steep down, on two of its sides, namely on the north side, which is towards Friedrich and Kunzendorf, and on the east side, where Weistritz Water, as yet only a Brook, gushes out from the Mountains,—hastening towards Schweidnitz or Schweidnitz Water; towards Lissa and Leuthen Country, where we have seen it on an important night. Weistritz, at this part, has scarped the eastern flank of Burkersdorf Height; and made for itself a pleasant little Valley there: this is the one Pass into the Mountains. A Valley of level bottom; where Daun has a terrific trench and sunk battery level with the ground, capable of sweeping to destruction whoever enters there without leave.

"East from Burkersdorf Lesser Height (which we neglect for the present), and a little farther inwards or south, are Two other Heights: Ludwigsdorf and Leuthmannsdorf; which also need capture, as adjuncts of Burkersdorf, or second line to Burkersdorf; and are abundantly difficult, though not so steep as Burkersdorf.

"The Enterprise, therefore, divides itself into two. Wied is to do the Ludwigsdorf-Leuthmannsdorf part; Mollendorf, the Burkersdorf. The strength of guns in these places, especially on Burkersdorf,—we know Daun's habit in that particular; and need say nothing. Man-devouring batteries, abatis; battalions palisaded to the teeth, 'the pales strong as masts, and room only for a musket-barrel between;' nay, they are 'furnished with a lath or cross-strap all along, for resting your gun-barrel on and taking aim:'—so careful is Daun. The ground itself is intricate, in parts impracticably steep; everywhere full of bushes, gnarls and impediments. Seldom was there such a problem altogether! Friedrich's position, as we say, is Kunzendorf Heights, with Schweidnitz and his old ground of Bunzelwitz to rear, Czernichef and others lying there, and Wurben and the old Villages and Heights again occupied as posts:—what a tale of Egyptian bricks has one to bake, your Majesty, on certain fields of this world; and with such insufficiency of raw-material sometimes!"

By the 16th of July, Friedrich's plans are complete. Contrived, I must say, with a veracity and opulent potency of intellect, flashing clear into the matter, and yet careful of the smallest practical detail. FRIDAY, 17th, Mollendorf, with men and furnitures complete, circles off northwestward by Wurben (for the benefit of certain on-lookers), but will have circled round to Burkersdorf neighborhood two days hence; by which time also Wied will be quietly in his place thereabouts, with a view to business on the 20th and 21st. Mollendorf, Wied and everything, are prosperously under way in this manner,—when, on the afternoon of that same Friday, 17th, [Compare Tempelhof, vi. 99, and Rodenbeck, ii. 164.] Czernichef steps over, most privately, to head-quarters: with what a bit of news! "A Revolution in Petersburg [JULY 9th, as we saw above, or as Herr Busching saw]; Czar Peter,—your Majesty's adorer, is dethroned, perhaps murdered; your Majesty's enemies, in the name of Czarina Catharine, order me instantly homeward with my 20,000!" This is true news, this of Czernichef. A most unexpected, overwhelming Revolution in those Northern Parts;—not needing to be farther touched upon in this place.

What here concerns us is, Friedrich's feelings on hearing of it; which no reader can now imagine. Horror, amazement, pity, very poignant; grief for one's hapless friend Peter, for one's still more hapless self! "The Sisyphus stone, which we had got dragged to the top, the chains all beautifully slack these three months past,—has it leapt away again? And on the eve of Burkersdorf, and our grand Daun problem!" Truly, the Destinies have been quite dramatic with this King, and have contrived the moment of hitting him to the heart. He passionately entreats Czernichef to be helpful to him,—which Czernichef would fain be, only how can he? To be helpful; at least to keep the matter absolutely secret yet for some hours: this the obliging Czernichef will do. And Friedrich remains, Czernichef having promised this, in the throes of desperate consideration and uncertainty, hour after hour,—how many hours I do not know. It is confidently said, [Retzow, ii. 415.] Friedrich had the thought of forcibly disarming Czernichef and his 20,000:—in which case he must have given up the Daun Enterprise; for without Czernichef as a positive quantity, much more with Czernichef as a negative, it is impossible. But, at any rate, most luckily for himself, he came upon a milder thought: "Stay with us yet three days, merely in the semblance of Allies, no service required of you, but keeping the matter a dead secret;—on the fourth day go, with my eternal thanks!" This is his milder proposal; urged with his best efforts upon the obliging Czernichef: who is in huge difficulty, and sees it to be at peril of his head, but generously consents. It is the same Czernichef who got lodged in Custrin cellars, on one occasion: know, O King,—the King, before this, does begin to know,—that Russians too can have something of heroic, and can recognize a hero when they see him! In this fine way does Friedrich get the frightful chasm, or sudden gap of the ground under him, bridged over for the moment; and proceeds upon Burkersdorf all the same.
