There is great jubilation among the troops here, for, following hard on the telegram announcing the Emperor’s departure from Berlin to the Rhine amid an unparalleled scene of excitement and enthusiasm, came a despatch reporting that Prince George of Saxony, by dint of forced marches of immense difficulty through the devious moors and marsh-grounds east of Rosenberg and Tarnowitz on the Kreuzburg-Tarnowitz line, had also succeeded in surprising the Russians at Czenstochau, on the Warsaw-Vienna Railway, and, capturing that important place, after a desperate but unavailing resistance on the part of its defenders, who, incredible to relate, consisted of not much more than its usual garrison—a brigade of infantry and two brigades of cavalry. But the German losses here were much more serious than with us yesterday, one infantry regiment in particular—the 22d Silesian—being more than decimated in its desperate, yet successful, endeavours to drive the enemy from a clump of wood, surmounted by a battery—a proof that it still continues to be animated by the heroic spirit of its name-chief, Field-Marshal James Keith, whilom of Inverugie and Dunnottar, in the Kingdom of Scotland, who, at its head, met his own death, under the eye of Frederick the Great, when saving the surprised right flank of the Prussian Army from utter annihilation by the Austrians at Hochkirch in the Lausitz. These two engagements, then, though on a smaller scale, have been the Wörth and Spichern of the present war; and it now only remains to be seen whether we shall be able to improve upon these initial successes—which were due to a great extent, I repeat, to the exceeding swiftness and daring of our own movements, as compared with the incredible slowness of our foes, and the faultiness of their mobilisation process, no less than to the fact that the Russians, imagining the Germans would never dare invade Poland, but remain upon their guard and form a flanking reserve support in Silesia to their Austrian allies, directed the main stream of their mobilisation further to the east, towards Dragomiroff’s line of hostile advance upon Lemberg and the Carpathian Passes to the south thereof at Stryj. How Gourko, who is known to be still at Warsaw, though the bulk of his forces must now be well in front of him, will endeavour to cope with the situation thus so suddenly created for him, is naturally the question which occupies all minds here, and it cannot be very long before his intentions are made manifest. Meanwhile the telegrams from Galicia, where our Austrian allies have concentrated the bulk of their forces, are not quite so encouraging, indicating, as they do, less initiative and promptitude of action on their part, as well as considerable difference of opinion in the minds of the Corps and Army Commanders as to whether they ought to remain on the defensive, or espouse an audacious policy of invasion like ourselves, and essay to beard the lion, or rather the bear, in his den.
