The Vienna people are in the depths of amazement and discouragement; almost of terror, had it not been for a few, or especially for one high heart among them. Feldmarschall Daun, on the news of May 6th, hastily fell back, joined by the wrecks of the right wing, which fled Sazawa way. Brunswick-Bevern, with a 20,000, is detached to look after Daun; finds Daun still on the retreat; greedily collecting reinforcements from the homeward quarter; and hanging back, though now double or so of Bevern's strength. Amazement and discouragement are the general feeling among Friedrich's enemies. Notable to see how the whole hostile world marching in upon him,--French, Russians, much more the Reich, poor faltering entity,--pauses, as with its breath taken away, at news of Prag; and, arrested on the sudden, with lifted foot, ceases to stride forward; and merely tramp-tramps on the same place (nay in part, in the Reich part, visibly tramps backward), for above a month ensuing! Who knows whether, practically, any of them will come on; [See CORRESPONDANCE DU COMTE DE SAINT-GERMAIN, an Eye-witness, i. 108 (cited in Preuss, ii. 50); &c. &c.] and not leave Austria by itself to do the duel with Friedrich? If Prag were but got, and the 46,000 well locked away, it would be very salutary for Friedrich's affairs!--Week after week, the City holds out; and there seems no hope of it, except by hunger, and burning their Magazines by red-hot balls.
