Having settled Soubise and recovered repute, Frederick must make haste to Silesia, where Prince Karl, along with Fabius Daun, is already proclaiming Imperial Majesty again, not much hindered by Bevern. Schweidnitz falls; Bevern, beaten at Breslau, gets taken prisoner; Prussian army marches away; Breslau follows Schweidnitz. This is what Frederick finds, three weeks after Rossbach. Well, we are one to three we will have at Prince Karl--soldiers as ready and confident as the king, their hero. Challenge accepted by Prince Karl; consummate manoeuvring, borrowed from Epaminondas, and perfect discipline wreck the Austrian army at Leuthen; conquest of Silesia brought to a sudden end. The most complete of all Frederick's victories. Next year (1758) the first effective subsidy treaty with England takes shape, renewed annually; England to provide Frederick with two-thirds of a million sterling. Ferdinand has got the French clear over Rhine already. Frederick's next adventure, a swoop on Olmütz, is not successful; the siege not very well managed; Loudon, best of partisan commanders, is dispatched by Daun to intercept a very necessary convoy; which means end of siege. Cautious Daun does not strike on the Prussian retreat, not liking pitched battles. However, it is now time to face an enemy with whom we have not yet fought; of whose fighting capacity we incline to think little, in spite of warnings of Marshal Keith, who knows them. The Russians have occupied East Prussia and are advancing. On August 25, Frederick comes to hand-grips with Russia--Theseus and the Minotaur at Zorndorf; with much ultimate slaughter of Russians, Seidlitz, with his calvary, twice saving the day; the bloodiest battle of the Seven Years' War, giving Frederick new views of Russian obstinacy in the field. The Russians finally retire; time for Frederick to be back in Saxony. For Daun has used his opportunity to invade Saxony; very cleverly checked by Prince Henri, while Frederick is on his way back. To Daun's surprise, the king moves off on Silesia. Daun moved on Dresden. Frederick, having cleared Silesia, sped back, and Daun retired. The end of the campaign leaves the two sides much as it found them; Frederick at least not at all annihilated. Ferdinand also has done excellently well. _V.--Frederick at Bay_ Not annihilated, but reduced to the defensive; best of his veterans killed off by now, exchequer very deficient in spite of English subsidy. The allies form a huge cordon all round; broken into at points during the spring, but Daun finds at last that Frederick does not mean any invasion; that he, Daun, must be the invader. But now and hereafter Fabius Cunctator waits for Russia.
