On the 27th General Von Flies, advancing through Warza upon Langensalza, with about 9,000 men, struck the army of King George, which was well posted on the left bank of the Unstrut river. A battle followed, in which the Hanoverians defeated Von Flies, and drove his army several miles towards Warza. But the Hanoverian victory was a barren one. Von Flies was reinforced at Warza by a strong detachment from Von Goeben’s division at Eisenach. Von Goeben and Von Beyer advanced from Eisenach upon Langensalza, and Von Manteuffel, moving _via_ Heiligenstadt, Worbis, Dingelstadt, Mühlhausen and Gross Gottern, closed upon the Hanoverians from the north. The army of King George was now surrounded by 40,000 Prussians, united under the command of Von Falckenstein. Further resistance was hopeless, and on the 29th of June the Hanoverians surrendered. The men were dismissed to their homes, the officers were paroled, and King George was banished from his kingdom. THE INVASION OF SAXONY, AND ITS RESULTS. In the meantime the main armies had not been idle. The invasion of Saxony was begun on the 16th of June by the Army of the Elbe and the First Army. On the night of the 15th of June the Saxon army began its retreat to Bohemia, detachments of pioneers tearing up the railroad track between Rieza and Dresden, and between the latter city and Bautzen. The work of destruction, except the burning of the bridge at Rieza, was hurriedly and imperfectly done, and did not appreciably delay the Prussian advance. The Army of the Elbe advanced from Torgau, _via_ Wurzen, Dahlen and Strehla; a division to each road, and a detachment from the right division moving _via_ Ostrau and Dobeln to cover the right flank. The First Army advanced from the neighborhood of Görlitz, through Löbau and Bautzen, a strong detachment being sent out on the Zittau road, beyond Ostritz, to observe the passes of Reichenberg and Gabel, for the army was making a flank march, and the Austrians might attack through these passes. A cavalry detachment was pushed out through Bischofswerda to feel the left of the Army of the Elbe. On the 18th of June the Army of the Elbe occupied Dresden, and pushed its outposts beyond the city as far as Lockwitz and Pillnitz. On the following day the junction of the two armies was perfected. The 1st Reserve Division was sent from Berlin to reinforce Herwarth Von Bittenfeld, and the combined forces of the Army of the Elbe and the First Army were placed under the command of Prince Frederick Charles. To guard against a possible invasion of Saxony by the Bavarians, measures were at once taken to fortify Dresden, which was occupied by the 2nd Reserve Division from Berlin; Leipsic and Chemnitz were occupied by Landwehr; and the Leipsic-Plauen railway beyond Werdau was destroyed.
